Description

  The present invention relates to a network system, a control node, a fixed node, an information processing method, and a program, and in particular, a network system, a control node, a fixed node, an information processing method for detecting unauthorized intrusion into an object to be alerted, And the program.

  Conventionally, various security systems have been proposed and used.

  In Japanese Patent Laid-Open No. 10-27292, when a facility such as a store is closed, a final exit person can return home by opening the final exit door only after locking the guard target door and setting the security mode. Making it possible is disclosed. In this system, the door for final exit can be freely opened from the inside during normal business hours until 5:00 in the evening, and after 5 pm, the door is opened on the condition that the security mode is set. It is. As a result, forgetting to set the security mode for reporting the doorbreak to the security company is prevented.

  In Japanese Patent Laid-Open No. 8-249550, the monitoring mode is sequentially changed in a loop by pressing one set button of the home security device for a time less than the first predetermined time within the second predetermined time. Is disclosed. After the second predetermined time has elapsed, the monitoring mode is determined, and a plurality of security sensors are set to the monitoring state. When the set button is pressed for a time exceeding the first predetermined time, the monitoring state of the plurality of security sensors is released by operating one set button. In this home security device, even when a plurality of security sensors are connected, the door lock monitoring state can be set / released by operating one set button.

  In Japanese Patent Application Laid-Open No. 2001-56887, a first sensor having a detection area on the front side of the alert target and the upper part thereof, and a first sensor having a detection area on the front side of the alert target and a lower part thereof. And at least one of the first sensor and the second sensor is provided with a logic circuit with a timer, and at least the other is an output that outputs a detection signal from a detection unit in the sensor to the outside. It is disclosed that a route is provided. The logic circuit with a timer outputs an alarm signal when a detection signal from a detection unit in the sensor provided with the logic circuit with a timer and a detection signal taken out through the output path of the other sensor are received within a predetermined time. appear. This avoids false alarms due to small animals and ambient light, and can correctly detect, for example, intrusions from openings such as windows and doorways of buildings that are subject to vigilance.

  In Japanese Patent Application Laid-Open No. 5-114091, the intrusion for dwelling outside that monitors a predetermined position outside the window within the past few seconds when the window is opened and the detection signal of the intrusion sensor for dwelling inside is input to the data processing unit. The sensor determines whether or not a sensing signal for detecting an intruder is input to the data processing unit. If the condition is satisfied as a result of the determination, the internal notification unit and a speaker are used for internal notification by sounding. At the same time, a higher level notification is made using a terminal that connects the higher level notification unit to the telephone line, an actual alarm is issued, and if the condition is not met, it is treated as a false alarm and no internal notification or higher level notification is performed. It is disclosed. As a result, it is possible to determine an actual alarm only when the window is opened from the outside and issue an intrusion alarm.

  According to the present invention, unauthorized intrusion can be detected. According to the present invention, it is possible to detect unauthorized intrusion and execute predetermined processing for unauthorized intrusion.

  FIG. 1 is a diagram showing an embodiment of a security system according to the present invention. In FIG. 1, a security system according to the present invention is installed in a house 1 that is an example of an object to be warned. In FIG. 1, a user 2-1 and a user 2-2 are legitimate members who use the house 1. The security system detects the position of unauthorized intrusion by the unauthorized intruder 3 and executes predetermined processing for the unauthorized intrusion.

  The security system according to the present invention includes a control localizer 11, a fixed localizer 12-1 to a fixed localizer 12-8, a mobile localizer 13-1, and a mobile localizer 13-2.

  Hereinafter, the fixed localizer 12-1 to the fixed localizer 12-8 are simply referred to as the fixed localizer 12 when it is not necessary to distinguish them individually. Hereinafter, when there is no need to distinguish between the mobile localizer 13-1 and the mobile localizer 13-2, they are simply referred to as the mobile localizer 13.

  In the security system of the present invention, the number of fixed localizers 12 may be three or more, and the number of mobile localizers 13 may be an arbitrary number.

  Furthermore, when the control localizer 11, the fixed localizer 12, and the moving localizer 13 do not need to be individually distinguished, they are simply referred to as localizers.

  Here, the localizer is an example of a terminal device and constitutes a node of the network system. In other words, a predetermined ID code can be transmitted wirelessly, the distance to another node can be measured wirelessly, or the position of the node itself can be measured. If there is an intruder 3), a node having a function capable of detecting the intrusion and wirelessly transmitting information detected by itself is referred to as a localizer.

  In other words, the localizer detects unauthorized intrusion by detecting a position change of the localizer itself or by detecting a human body between the localizers (sensing area).

  The fixed localizer 12 is an object to be warned, and is basically fixed to an object whose position does not change (does not move), and the position of the fixed localizer 12 does not basically change. The control localizer 11 is an object to be warned, and is fixed to an object whose position does not change (does not move), and the position of the control localizer 11 does not change. Further, the control localizer 11 further has a control function of integrating and storing external communication functions and status information of all localizers in the system.

  The control localizer 11 and the fixed localizer 12 fix the window glass of the house 1, the vicinity of the indoor window frame, the surface of the indoor door, the surface of the indoor wall or ceiling, the wall of the outdoor housing, the outdoor pillar, the gate pillar, etc. It is fixed to the object. The localizer is also fixed to an outdoor vehicle 7, an indoor electrical product, a safe 6, or the like that is likely to be stolen.

  However, the mobile localizer 13 is attached to the vehicle 7 on the premise of movement. Even if the mobile localizer 13 is stationary for a predetermined time or longer, the mobile localizer 13 is automatically incorporated into the wireless network system including the fixed localizer 12 as the fixed localizer 12.

  For example, as shown in FIG. 1, the control localizer 11 is fixed inside the wall of the house 1. The fixed localizer 12-1, the fixed localizer 12-2, and the fixed localizer 12-3 are fixed inside the wall of the house 1.

  The fixed localizer 12-4 is fixed inside the door 5 of the house 1. The fixed localizer 12-5 is fixed inside the window 4 of the house 1. The fixed localizer 12-6 is fixed to the safe 6.

  Further, the fixed localizer 12-7 is fixed to a building outside the house 1. Further, the fixed localizer 12-8 (or the moving localizer 13) is fixed to the vehicle 7.

  The position of the control localizer 11 is the origin of a position measurement coordinate system (three-dimensional coordinate system).

  Then, three fixed localizers 12 are arranged in the positive direction of the X axis, the Y axis, and the Z axis, for example, around the control localizer 11, and the fixed localizer 12 is based on the positions of the control localizer 11 and the three fixed localizers 12. Alternatively, a reference coordinate system (three-dimensional coordinate system) for measuring the position on the three-dimensional coordinate of the moving localizer 13 is set.

  Thereafter, still another fixed localizer 12 is arranged in the monitoring target area inside and outside the house 1, and the position of the arranged fixed localizer 12 on the three-dimensional coordinates is registered (stored).

  The user 2-1 and the user 2-2 who are legitimate members of the house 1 such as a family and a living person hold the mobile localizer 13 that can transmit the ID code wirelessly.

  The control localizer 11 virtually sets an external security surface 22 so as to surround the home 1 outside the home 1, and includes one or more internal security surfaces so as to surround a designated area in the home 1 inside the home 1. 21 is virtually set.

  That is, the internal security surface 21 can be present only inside the external security surface 22.

  When all of the mobile localizers 13 have come out of the external security surface 22, an answering machine warning process is automatically executed. When all of the mobile localizers 13 enter the inside of the internal security surface 21 from the inside of the external security surface 22, the home security processing is automatically executed.

  When one or more mobile localizers 13 are present in the area between the internal security surface 21 and the external security surface 22, a non-warning process is automatically executed.

  As will be described later with reference to FIG. 15, when the internal security surface 21 is not set, for example, when applied to the vehicle 7, when all of the mobile localizers 13 are out of the external security surface 22, the answering machine warning process is executed. Otherwise, a non-warning process is executed. In this case, the external security surface 22 is set for the vehicle 7.

  The internal security surface 21 and the external security surface 22 are set as follows. That is, after installing the fixed localizer 12 inside and outside the house 1, the control localizer 11 is set to the external warning plane setting mode.

  Then, when the user 2-1 and the user 2-2 holding (wearing) the mobile localizer 13 move outside the house 1 and come to a position to be registered as a point on the external security surface 22, the mobile localizer 13 Press the location registration button. By executing this operation at a sufficient number of positions for specifying the external security surface 22, the position on the external security surface 22 in the three-dimensional coordinates is registered. From the position on the external security surface 22 in the three-dimensional coordinates registered in this way, a parameter for determining a rectangular parallelepiped for determining the external security surface 22 is obtained.

  Next, one or more internal security surfaces 21 are set. First, by operating the control localizer 11, the control localizer 11 is set to the internal warning plane setting mode. Then, the user 2-1 and the user 2-2 holding (attaching) the moving localizer 13 move for setting the internal security surface 21, while pressing the position registration button at an appropriate position and pressing the position registration button. A plurality of positions of the moving localizer 13 on the three-dimensional coordinates are recorded for each internal warning surface 21 (the surface of the closed internal warning area). A rectangular parallelepiped parameter for determining the internal security surface 21 is obtained from a plurality of points on the three-dimensional coordinates thus registered. When all the internal warning surfaces 21 to be set are set, the control localizer 11 is set to the execution mode.

  As a result, the security system automatically switches between the answering machine alert process, the home alert process, and the non-alert process in accordance with the position of the mobile localizer 13 and the positional relationship between the internal alert surface 21 and the external alert surface 22. Run while. If an actuator (for example, a speaker or a white smoke generating unit) is built in the localizer, the localizer close to the position of the unauthorized intruder 3 generates a warning sound when an unauthorized intrusion is detected in the answering machine alert processing. Or generate white smoke. When the unauthorized intruder 3 moves in the house, the localizer closer to the location of the intruder generates a warning sound or white smoke, so that the multiple localizers follow the unauthorized intruder 3 in order, A warning sound or white smoke is generated.

  In the home security process, the operation of the actuator is controlled so that the unauthorized intruder 3 does not easily approach the internal security surface 21, and the user 2-1 and the user 2-2 in the internal security surface 21 are protected from the unauthorized intruder 3. Control the actuator so that you can evacuate away.

  Applicant has developed a wireless network system that detects anomalies by comparing each distance between nodes during normal operation (distance matrix) and each distance between nodes during monitoring (distance matrix). It is called a system and its concept is shown on the following website. Hereinafter, a matrix having the distance between nodes as an element is referred to as a distance matrix.

Internet <URL: http: //www.hagoromoweb.com/>
The Hagoromo system is also described in the specification of US Patent No. 10 / 200,552 (filing date: July 23, 2002), in which one of the inventors of the present application became an inventor and applied for a patent.

  In the present invention, in a security system that is a wireless network system including a control localizer 11 and a fixed localizer 12, a matrix of distances between localizers (a matrix in which the distance between the localizer s and the localizer t is Distance (s, t)) is used. Monitor.

  Next, the localizer will be described in more detail.

  More preferably, the localizer contains a battery. Even if the unauthorized intruder 3 cuts off the power supplied to the house 1 (so-called AC (Alternating Current) power) and enters the local area, if the localizer is operated by a built-in battery, the local intruder 3 is predetermined for unauthorized intrusion. This is because it becomes possible to execute the process. The localizer can be provided with various types of batteries such as fuel cells or lithium ion batteries.

  Further, the localizer may be provided with a rechargeable battery and used with an AC power source. You may make it provide a solar cell further in the localizer installed outdoors. Furthermore, the indoor localizer may use an AC power source. As a result, the frequency of battery replacement can be reduced, and accordingly, maintenance labor and costs can be reduced.

  In order to easily attach the localizer to an object (more specifically, a wall, a door, a safe, glass, or the like of the house 1), for example, a hook and loop fastener of Velcro or Kuraray can be used.

  As the localizer, the technique disclosed in US Pat. No. 5,748,891 may be used. According to this technique, the localizer can measure the distance between the localizers, and can detect a change in the waveform of the radio signal transmitted between the localizers that is generated when an object exists in the space between the localizers. The control localizer 11 collects information indicating whether there is an object in the distance between the localizers or in the space between the localizers using a communication function between the localizers.

  Further, the localizer may be realized by using the technology disclosed in JP 2002-228744 A or JP 2000-111638 A together with the GPS (Global Positioning System) technology and the wireless communication technology. That is, in this case, the distance to the object between the nodes is measured by the radar function, the position of the node is measured by the function of the GPS receiver held in the node, and the distance information to the detected object is detected between the nodes. The node position information is transmitted to other nodes by the wireless communication function.

Based on the received pulse train supplied from the wireless transmission / reception unit 104, the distance measuring unit 103 determines the mobile localizer based on the time difference between the time when the other localizer, which is the counterpart, transmits the pulse train, and the time when the mobile localizer 13 receives the pulse train. The distance between 13 and the opponent is calculated. The distance measurement unit 103 supplies information indicating the distance between the mobile localizer 13 and the opponent to the control unit 101.

  The wireless transmission / reception unit 104 modulates the signal supplied from the distance measurement unit 103 or the data communication unit 106 using the network ID supplied from the ID code processing unit 107 and supplies the modulated signal to the antenna unit 105. By transmitting a signal. The wireless transmission / reception unit 104 demodulates the received signal using the network ID supplied from the ID code processing unit 107 via the antenna unit 105. The wireless transmission / reception unit 104 supplies the demodulated signal to the distance measurement unit 103 or the data communication unit 106.

  By doing so, communication with localizers belonging to other network systems, that is, interference is prevented.

  When receiving a signal from the other party, the antenna unit 105 receives a radio wave from the other party and supplies a signal corresponding to the received radio wave to the wireless transmission / reception unit 104. Further, when receiving a signal to the other party, the antenna unit 105 radiates a radio wave based on the signal supplied from the wireless transmission / reception unit 104 and transmits the signal to the other party wirelessly.

  The data communication unit 106 communicates various data with other localizers via the wireless transmission / reception unit 104 and the antenna unit 105 under the control of the control unit 101.

  The ID code processing unit 107 stores a unique localizer ID of the mobile localizer 13 and a network ID assigned to each network system to which the mobile localizer 13 belongs and that identifies the network system. The ID code processing unit 107 supplies the localizer ID and the network ID to the wireless transmission / reception unit 104.

  The control unit 101 is connected to a speaker 108 for generating alarm sound.

  The operation button 109 supplies a signal for selecting a mode to the control unit 101 in accordance with the operations of the user 2-1 and the user 2-2.

  The power supply unit 110 includes a battery or the like and supplies power to each part of the mobile localizer 13.

  Next, setting of the three-dimensional coordinate system in the security system as the network system according to the present invention will be described.

  When the user 2-1 or the user 2-2 who is an operator operates the input unit 51, the mode of the control localizer 11 shifts to the coordinate system setting mode. Then, the operator selects the fixed localizer 12-1 among the fixed localizers 12 already attached, and presses the operation button 80 of the fixed localizer 12-1.

  Then, the control localizer 11 and the fixed localizer 12-1 measure the distance between them, and the control localizer 11 is a one-dimensional one having the control localizer 11 as the origin and the fixed localizer 12-1 in the positive direction of the X axis. Set the coordinate system.

  Next, the operator selects the fixed localizer 12-2 that is on the same plane as the control localizer 11 and the fixed localizer 12-1, and presses the operation button 80 attached to the fixed localizer 12-2. Then, the control localizer 11 and the fixed localizer 12-1 each measure the distance to the fixed localizer 12-2. The fixed localizer 12-1 transmits information indicating the distance from the fixed localizer 12-1 to the fixed localizer 12-2 to the control localizer 11.

  Here, the distance between the control localizer 11 and the fixed localizer 12 is represented by a distance a, and the distance between the control localizer 11 and the fixed localizer 12-2 is represented by a distance b. Further, the distance between the fixed localizer 12-1 and the fixed localizer 12-2 is represented by a distance c.

  As shown in FIG. 5, equations (1) and (2) are established for the position (x2, y2) on the two-dimensional coordinate of the fixed localizer 12-2.

・・・（１）

・・・（２）

... (1)

... (2)

  In this coordinate system, the control localizer 11 exists at the origin, and the position of the control localizer 11 on the three-dimensional coordinate is (0, 0, 0). The position on the three-dimensional coordinate of the fixed localizer 12-1 is (a, 0, 0). The position of the fixed localizer 12-2 on the three-dimensional coordinate is (x2, y2, 0).

  Next, as shown in FIG. 1, the operator is not on a plane formed by the three localizers of the control localizer 11, the fixed localizer 12-1, and the fixed localizer 12-2 (a position off the plane). The fixed localizer 12-3 is selected, and the operation button 80 attached to the fixed localizer 12-3 is pressed.

  After the three-dimensional coordinates determined by the positions of the control localizer 11, the fixed localizer 12-1, and the fixed localizer 12-2 are determined, the operation determines the distance between the control localizer 11 and the fixed localizer 12-3, and the fixed localizer 12-1. And the distance between the fixed localizer 12-3 and the distance between the fixed localizer 12-2 and the fixed localizer 12-3. The fixed localizer 12-1 to the fixed localizer 12-3 are the distance between the control localizer 11 and the fixed localizer 12-3, the distance between the fixed localizer 12-1 and the fixed localizer 12-3, and the fixed localizer 12-2 and the fixed localizer. Information indicating the distance to 12-3 is transmitted to the control localizer 11.

  The control localizer 11 receives the received distance between the control localizer 11 and the fixed localizer 12-3, the distance between the fixed localizer 12-1 and the fixed localizer 12-3, and the distance between the fixed localizer 12-2 and the fixed localizer 12-3. Based on the information indicating the distance, the position (x3, y3, z3) of the fixed localizer 12-3 on the three-dimensional coordinates is solved by solving simultaneous equations with the position on the three-dimensional coordinates of the fixed localizer 12-3 as an unknown. Ask for.

  The control localizer 11 stores information indicating the position of each fixed localizer 12 on the three-dimensional coordinates in association with the localizer ID of the fixed localizer 12.

  In this way, if the distance between the fixed localizer 12 or the moving localizer 13 and the fixed localizer 12 or the moving localizer 13 in which three or more control localizers 11 and fixed localizers 12 whose positions on the three-dimensional coordinates are known is obtained, the simultaneous equations are used to pay attention. The position of the three-dimensional coordinates of the fixed localizer 12 or the moving localizer 13 can be obtained.

  As described above, it can be said that the setting of the three-dimensional coordinate system is completed when the desired fixed localizer 12 or the movable localizer 13 can be obtained on the three-dimensional coordinates.

  When the setting of the three-dimensional coordinate system of the network system is completed, each fixed localizer 12 in the network system measures the distance from the fixed localizer 12 in which the three-dimensional coordinates are already registered, and includes the measured distance. The measurement distance transmission information in the format shown is transmitted to the control localizer 11.

Measurement distance transmission information:
(Own node number, partner node number, distance between own node and partner node)
Here, the local node number and the counterpart node number can be a localizer ID. In addition, the local node number and the counterpart node number may be node numbers given at the time of registration in the network system, for example, indicating the order of registration.

  The control localizer 11 stores a matrix of distances between localizers or a list of position coordinates of the localizer as a Fingerprint that is unique information regarding the network system including the control localizer 11 and the fixed localizer 12. When the element of the inter-localizer distance matrix indicating the distance between the localizer s and the localizer t is M (s, t), M (s, t) is expressed by the following equation (3).

・・・（３）
ここで、Distance(s,t)は、ローカライザｓとローカライザtの間の距離を示す値である。

... (3)
Here, Distance (s, t) is a value indicating the distance between the localizer s and the localizer t.

  Next, the setting of the external security surface 22 and the internal security surface 21 will be described.

  First, the external security surface 22 is set.

  When the setting of the three-dimensional coordinate system is completed, the user 2-1 or the user 2-2 who is an operator operates the input unit 51 of the control localizer 11 to change the mode of the control localizer 11 to the setting mode of the external warning surface 22. To migrate.

  Then, the operator sets the external security surface 22 as follows while carrying one mobile localizer 13.

  As a first step, the operator moves the movement localizer 13 to the vicinity considered to be on the external security surface 22. As a second step, the operation button 109 as the position registration button of the moving localizer 13 is pressed. Then, as a third step, each of the fixed localizers 12 measures the distance from itself to the moving localizer 13 at that time, and transmits the measured distance to the control localizer 11 as measurement distance transmission information in the format described above. . The control localizer 11 is based on the distance between each fixed localizer 12 and the moving localizer 13 included in the measured distance transmission information transmitted from each fixed localizer 12, and the position of the moving localizer 13 on the three-dimensional coordinates. And the position of the calculated movement localizer 13 on the three-dimensional coordinates is stored as a registration point.

  The first to third steps are repeated until the number of registration points reaches a predetermined number, for example, 10 points. However, the operator registers the position on the three-dimensional coordinate so that the line connecting the registration points exists on all the surfaces of the assumed external security surface 22.

  As a fourth step, the control localizer 11 obtains a minimum rectangular parallelepiped surrounding the registered registration point. However, the floor surface of the smallest rectangular parallelepiped is a surface that is one meter below the average value of the z coordinate positions (positions in the vertical direction on the three-dimensional coordinates) of the respective registration points. The surface is 1 meter above the average value of the z-coordinate positions of the registration points (the vertical position on the three-dimensional coordinates). This is because it is often difficult to position the mobile localizer 13 near the floor surface or near the ceiling surface, or an operator is required to take an unreasonable posture.

  As a fifth step, the control localizer 11 enlarges the minimum cuboid obtained in the process of the fourth step by a predetermined ratio (for example, 150%) around the center point of the minimum cuboid, and expands the surface of the expanded cuboid. Register (store) the external security surface 22. This is because it is assumed that it is difficult to move outside the house 1 with the mobile localizer 13 in order to provide a registration point outside the house 1. The external security surface 22 can be set on the outside.

  Next, the internal warning surface 21 is set.

  The internal security surface 21 is set when a valid member such as the user 2-1 and the user 2-2 is at home, as in the home security system, when it is wary of intrusion from the outside. If there is no legitimate member movement localizer 13) between the internal security surface 21 and the external security surface 22, there will be no person to monitor for unauthorized intrusion beyond the external security surface 22. By setting 21, the security system can automatically execute a monitoring process between the internal security surface 21 and the external security surface 22.

  The user 2-1 or the user 2-2 who is an operator operates the input unit 51 of the control localizer 11 to shift the mode of the control localizer 11 to the setting mode of the internal warning surface 21. Then, the operator sets the internal security surface 21 as follows while carrying one mobile localizer 13.

  As a first step, the operator moves the movement localizer 13 to the vicinity considered to be on the internal security surface 21. As a second step, the operation button 109 as the position registration button of the moving localizer 13 is pressed. Then, as a third step, each of the fixed localizers 12 measures the distance from itself to the moving localizer 13 at that time, and transmits the measured distance to the control localizer 11 as measurement distance transmission information in the format described above. . The control localizer 11 is based on the distance between each fixed localizer 12 and the moving localizer 13 included in the measured distance transmission information transmitted from each fixed localizer 12, and the position of the moving localizer 13 on the three-dimensional coordinates. And the position of the calculated movement localizer 13 on the three-dimensional coordinates is stored as a registration point.

  The first to third steps are repeated until the number of registration points reaches a predetermined number, for example, 10 points. However, the operator registers the position on the three-dimensional coordinate so that the line connecting the registration points exists on all the assumed internal guard surfaces 21.

  As a fourth step, the control localizer 11 obtains a minimum rectangular parallelepiped surrounding the registered registration point. However, the floor surface of the smallest cuboid is a surface that is 1 meter below the average value of the z coordinate positions (positions in the vertical direction of the three-dimensional coordinates) of the respective registration points. The surface is one meter above the average value of the z-coordinate positions of the points (the vertical position of the three-dimensional coordinates). This is because it is often difficult to position the mobile localizer 13 near the floor surface or near the ceiling surface, or an operator is required to take an unreasonable posture.

  As a fifth step, the control localizer 11 registers (stores) the minimum rectangular parallelepiped obtained in the process of the fourth step as the internal warning surface 21.

  When a non-warning process is performed when a legitimate person is present inside the vehicle 7, the process of setting the internal warning surface 21 is omitted.

  A specific example when applied to a home security system will be described with reference to FIG.

  In the example illustrated in FIG. 1, the control localizer 11 is installed on a wall in a room of a house 1 that is an example of an object to be warned. And the fixed localizer 12-1 and the fixed localizer 12-2 are installed in the wall in which the control localizer 11 is installed. Furthermore, the fixed localizer 12-3 is installed on a wall different from the wall on which the control localizer 11 is installed.

  Each localizer is fixed to an object with a hook-and-loop fastener.

  In the above-described processing, a three-dimensional coordinate system with the control localizer 11 as the origin is set, and the positions on the three-dimensional coordinates of all the fixed localizers 12 are measured. The control localizer 11 corresponds to the localizer ID of each localizer. The position on the three-dimensional coordinate of each localizer is stored.

  In addition, an external security surface 22 and an internal security surface 21 are set. At this time, the user 2-1 and the user 2-2 who are legitimate members (residents) of the house 1 wear the mobile localizer 13 on their bodies like a pendant or a wristwatch.

  As shown in FIG. 1, even if one internal security surface 21 is set inside one external security surface 22, as shown in FIG. The internal security surface 21, that is, the internal security surface 21-1 and the internal security surface 21-2 may be set. In this case, the process of setting the internal security surface 21 is executed twice. In addition, the number of the internal warning surfaces 21 can be made into arbitrary numbers.

  When the external security surface 22 is registered and the internal security surface 21 is registered as necessary, execution mode processing is executed based on the registered external security surface 22 or the internal security surface 21.

  Even during the execution of this execution mode, when the switch of the input unit 51 of the control localizer 11 is operated, the mode is shifted to another mode (for example, the setting mode of the external warning surface 22). That is, the process in the execution mode is ended by the process in step S7 in FIG. 7 described later, and the execution of the process in another mode to be started is started.

  In this execution mode, the activated process is automatically switched according to the positional relationship between the mobile localizer 13, the external security surface 22, and the internal security surface 21. That is, one of the three processes of the answering machine alarm process, the home alarm process, and the non-alarm process is automatically activated when appropriate.

  Next, processing in the execution mode will be described with reference to the flowchart of FIG.

  In step S1, the control localizer 11 and the fixed localizer 12 measure the positions of all mobile localizers 13 that transmit the ID codes (network IDs) of the legitimate members.

  That is, the control localizer 11 transmits an instruction to measure and report the distance from the mobile localizer 13 to each fixed localizer 12 in the network system. The distance measuring unit 73 of each fixed localizer 12 that has received the instruction measures the distance to each moving localizer 13.

  Each of the fixed localizers 12 notifies the control localizer 11 of the distance to the mobile localizer 13 by transmitting to the control localizer 11 measurement distance transmission information in the above-described format indicating the distance between the fixed localizer 12 and each of the mobile localizers 13. To do.

  Further, the distance measuring unit 43 of the control localizer 11 measures the distance from the moving localizer 13. The control localizer 11 calculates and stores the position of each mobile localizer 13 on the three-dimensional coordinates based on the measurement result of the distance from the mobile localizer 13 and the notification from each fixed localizer 12.

  In step S <b> 2, the control unit 41 of the control localizer 11 determines whether there is a mobile localizer 13 that has succeeded in position measurement. That is, the control localizer 11 does not have the mobile localizer 13 at a place where the distance from the fixed localizer 12 can be measured, or even if it exists, the battery power supply is lost and the distance is measured. If there is only the mobile localizer 13 that cannot be used, it is determined that there is no mobile localizer 13 that has successfully measured the position. Further, since the control localizer 11 and the fixed localizer 12 cannot communicate with the mobile localizer 13 belonging to another network system and cannot measure the distance between them, only the mobile localizer 13 belonging to another network can communicate and measure distance. If not, it is determined that there is no mobile localizer 13 that has successfully measured the position.

  The mobile localizer 13 communicates or measures a mutual distance by a signal modulated using a network ID that is an ID code unique to the network system to which the mobile localizer 13 belongs. If there is one or more mobile localizers 13 that belong to the network system to which the mobile localizer 13 belongs and have succeeded in position measurement, it is determined that there is a mobile localizer 13 that has succeeded in position measurement.

  If it is determined in step S2 that there is a mobile localizer 13 that has successfully measured the position, the process proceeds to step S3, and the control localizer 11 of the control localizer 11 has the mobile localizer 13 located inside the external security surface 22. It is determined whether or not. The control localizer 11 compares the position on the coordinate indicating the range of the external security surface 22 with the position on the coordinate of the mobile localizer 13 to determine whether the mobile localizer 13 located inside the external security surface 22 exists. Determine whether or not.

  In step S3, when it is determined that there is a moving localizer 13 located inside the external security surface 22, the process proceeds to step S4, and the control unit 41 of the control localizer 11 determines whether or not the internal security surface 21 is set. judge.

  For example, when a legitimate member using the house 1 is sleeping in a bedroom at night, the bedroom area is set as the internal security surface 21. Thereby, the network system in the bedroom is appropriately controlled, and the operation of the actuator (for example, the white smoke generating module 49) is controlled so that the unauthorized intruder 3 does not approach the internal security surface 21 (for example, the bedroom). Can do.

  If it is determined in step S4 that the internal security surface 21 is set, the process proceeds to step S5.

  In step S <b> 5, the control unit 41 of the control localizer 11 determines whether all of the mobile localizers 13 that have successfully measured the position are located inside the internal warning surface 21. For example, in step S5, when the internal security surface 21 is a bedroom, it is determined whether or not a legitimate member using the house 1 is in the bedroom.

  If it is determined in step S5 that all of the mobile localizers 13 that have successfully measured the position are not located inside the internal alert surface 21, the process proceeds to step S6, and the control localizer 11 executes a non-alert process, Proceed to step S7. Details of the non-warning process will be described later.

  If it is determined in step S5 that all of the mobile localizers 13 that have successfully measured the position are not located inside the internal security surface 21, the mobile localizers 13 located inside the external security surface 22 are determined in step S3. Since it is determined that the internal security surface 21 has been set in step S4, for example, as shown in FIG. 8, any one of the mobile localizer 13-1 to the mobile localizer 13-3 is used. Is located outside the internal security surface 21 and inside the external security surface 22. In such a case, it is not necessary to perform a warning process, so a non-warning process is executed.

  In step S7, the control unit 41 of the control localizer 11 determines whether or not mode switching has been instructed. For example, in step S <b> 7, the control localizer 11 checks whether or not an operation for shifting to another mode such as setting of the internal warning surface 21 or setting of the external warning surface 22 has been applied to the input unit 51.

  If it is determined in step S7 that mode switching has not been instructed, the process returns to step S1 and the above-described processing is repeated.

  If it is determined in step S7 that mode switching has been instructed, the execution mode processing ends.

  If it is determined in step S5 that all of the mobile localizers 13 that have successfully measured the position are located inside the internal warning surface 21, the process proceeds to step S8, and the control localizer 11 executes the home warning process. Proceed to S7. Details of the home security process will be described later.

  If it is determined in step S5 that all of the mobile localizers 13 that have successfully measured the position are located inside the internal security surface 21, there are mobile localizers 13 located inside the external security surface 22 in step S3. Then, in step S4, since it is determined that the internal security surface 21 is set, for example, as shown in FIG. 9, both the mobile localizer 13-1 and the mobile localizer 13-2 are It is located inside the internal security surface 21. In such a case, since it is necessary to protect the legitimate member inside the internal warning surface 21, the at-home warning process is executed.

  If it is determined in step S4 that the internal warning surface 21 is not set, the process proceeds to step S9, the control localizer 11 performs a non-warning process, and then proceeds to step S7.

  If it is determined in step S3 that there is no mobile localizer 13 located inside the external security surface 22, or if it is determined in step S2 that there is no mobile localizer 13 that has successfully measured the position, that is, If the positions of all the mobile localizers 13 that have been successfully measured for positions are outside the external alert surface 22, the process proceeds to step S10, and the control localizer 11 executes the answering alert process, and proceeds to step S7.

  This means that, for example, as shown in FIG. 10, immediately after the legitimate member wearing the mobile localizer 13 leaves the house 1, the security system automatically executes the answering alert processing.

  In the conventional home security system, when the user is away from the house, the user has to perform a button operation for setting the alarm answering mode. Forgetting this, the home security system often does not work when the kidneys are serious. . The home security system according to the present invention does not require a troublesome operation and surely executes processing for protecting the target.

  Next, details of the non-warning process will be described.

  FIG. 11 is a flowchart illustrating details of the non-warning process corresponding to the process of step S6 or step S9 of FIG.

  In step S <b> 21, the control localizer 11 and each fixed localizer 12 measure the distance between the control localizer 11 and the fixed localizer 12 and the mutual distance between the fixed localizers 12.

  For example, the distance measurement unit 43 of the control localizer 11 measures the distance between the control localizer 11 and each fixed localizer 12 based on the control of the control unit 41 and supplies the measurement result to the control unit 41. The distance measuring unit 73 of each fixed localizer 12 measures the distance between itself and another fixed localizer 12 based on the control of the control unit 71. The control unit 71 of each fixed localizer 12 causes the wireless transmission / reception unit 74 to transmit measurement distance transmission information indicating the distance between itself and another fixed localizer 12 obtained by measurement to the control localizer 11.

  The control unit 41 of the control localizer 11 causes the wireless transmission / reception unit 44 to receive measurement distance transmission information indicating the mutual distance of the fixed localizers 12 transmitted from the respective fixed localizers 12. The control unit 41 of the control localizer 11 acquires measurement distance transmission information indicating the mutual distance of the fixed localizer 12 received by the wireless transmission / reception unit 44 via the data communication unit 46.

  In step S <b> 22, the control localizer 11 generates a localizer distance matrix indicating the distance between the control localizer 11 and the fixed localizer 12 and the mutual distance between the fixed localizers 12. For example, the control unit 41 of the control localizer 11 determines the localizer based on the measured distance transmission information indicating the distance between the control localizer 11 and each fixed localizer 12 and the mutual distance between the fixed localizers 12 acquired in the process of step S21. By arranging a value indicating the distance between the control localizer 11 and each fixed localizer 12 and a value indicating the mutual distance between the fixed localizers 12 in the order of the ID values, the distance between the control localizer 11 and each fixed localizer 12 is arranged. And an inter-localizer distance matrix having the mutual distances of the fixed localizer 12 as elements.

  In step S23, the control localizer 11 stores the inter-localizer distance matrix. For example, in step S <b> 23, the control unit 41 of the control localizer 11 stores the inter-localizer distance matrix in the memory 42.

  In step S24, the control localizer 11 and each fixed localizer 12 perform self-diagnosis. For example, in step S <b> 24, the control localizer 11 and each fixed localizer 12 diagnose each unit constituting itself.

  More specifically, for example, in step S24, the control localizer 11 and each fixed localizer 12 indicate the remaining amount of the battery of the power supply unit 53 or the power supply unit 81 or the white smoke of the white smoke generation module 49 or the white smoke generation module 79. Self-diagnosis by checking the remaining amount of raw materials. More specifically, the control localizer 11 and each fixed localizer 12 compare the remaining battery level of the power supply unit 53 or the power supply unit 81 with a predetermined threshold value, or the white smoke of the white smoke generation module 49 or the white smoke generation module 79. The self-diagnosis is performed by comparing the remaining amount of the raw material or the like with another predetermined threshold. The fixed localizer 12 notifies the control localizer 11 of the result of the self-diagnosis.

  In step S <b> 25, the control unit 41 of the control localizer 11 determines whether or not there is a defect based on the self-diagnosis result of the control localizer 11 and the self-diagnosis result of each fixed localizer 12 notified from each fixed localizer 12. Determine.

  If it is determined in step S25 that there is a problem, the process proceeds to step S26, and the control unit 41 of the control localizer 11 operates the speaker 48 or the display unit 52 to notify the user 2-1 and the user 2-2 of the problem. The non-warning process ends. For example, in step S <b> 26, the control unit 41 causes the speaker 48 to output a sound that notifies the content of the problem. Alternatively, for example, in step S <b> 26, the control unit 41 causes the display unit 52 to display an image or characters that notify the content of the defect.

  If it is determined in step S25 that there is no defect, there is no need to notify the defect, so the process in step S26 is skipped and the non-warning process ends.

  Note that the processing from step S21 to step S26 may be repeated.

  Next, the details of the home security process will be described.

  FIG. 12 is a flowchart for explaining the details of the home security process corresponding to the process of step S8 of FIG.

  In step S <b> 41, the control localizer 11 and each fixed localizer 12 measure the distance between the control localizer 11 and the fixed localizer 12 and the mutual distance between the fixed localizers 12.

  For example, the distance measurement unit 43 of the control localizer 11 measures the distance between the control localizer 11 and each fixed localizer 12 based on the control of the control unit 41 and supplies the measurement result to the control unit 41. The distance measuring unit 73 of each fixed localizer 12 measures the distance between itself and another fixed localizer 12 based on the control of the control unit 71. The control unit 71 of each fixed localizer 12 causes the wireless transmission / reception unit 74 to transmit measurement distance transmission information indicating the distance between itself and another fixed localizer 12 obtained by measurement to the control localizer 11.

  The control unit 41 of the control localizer 11 causes the wireless transmission / reception unit 44 to receive measurement distance transmission information indicating the mutual distance of the fixed localizers 12 transmitted from the respective fixed localizers 12. The control unit 41 of the control localizer 11 acquires measurement distance transmission information indicating the mutual distance of the fixed localizer 12 received by the wireless transmission / reception unit 44 via the data communication unit 46.

  In step S <b> 42, the control localizer 11 generates an inter-localizer distance matrix indicating the distance between the control localizer 11 and the fixed localizer 12 and the mutual distance between the fixed localizers 12. For example, the control unit 41 of the control localizer 11 determines the localizer based on the measured distance transmission information indicating the distance between the control localizer 11 and each fixed localizer 12 and the distance between the fixed localizers 12 acquired in the process of step S41. By arranging a value indicating the distance between the control localizer 11 and each fixed localizer 12 and a value indicating the mutual distance between the fixed localizers 12 in the order of the ID values, the distance between the control localizer 11 and each fixed localizer 12 is arranged. And an inter-localizer distance matrix having the mutual distances of the fixed localizer 12 as elements.

  In step S43, the control unit 41 of the control localizer 11 stores the generated inter-localizer distance matrix for the control localizer 11 and the fixed localizer 12 inside the external security surface 22 and outside the internal security surface 21. It is determined whether there is a difference in the localizer distance matrix.

  In the non-warning process, the stored inter-localizer distance matrix is updated to a value indicating the distance between the localizers at that time (when the non-warning process is executed). Accordingly, in step S43, a difference between the last updated localizer distance matrix and the current localizer distance matrix is detected. This difference is calculated as the sum of the absolute values of the differences for each corresponding element in the range where the distance can be measured in the stored inter-localizer distance matrix and the current inter-localizer distance matrix.

  However, in order not to detect an abnormality (to prevent a false detection) due to the movement of legitimate members such as the user 2-1 and the user 2-2 of the house 1 in the internal security surface 21, the internal security surface 21 The difference caused by the movement of the localizer itself is not used for the calculation of this sum.

  If this sum exceeds a predetermined threshold value, the control unit 41 determines that there is a difference, that is, there is an abnormality. As shown in FIG. 1, if the fixed localizer 12 is attached to the window 4, the door 5, or the safe 6, the window 4 moves (opens), the door 5 moves (if opened), The distance between the localizer attached to the window 4 or the door 5 and another localizer changes. The same applies when the safe 6 moves. As a result, the inter-localizer distance matrix changes.

  In step S43, there is no difference in the generated inter-localizer distance matrix and the stored inter-localizer distance matrix for the control localizer 11 and the fixed localizer 12 inside the external security surface 22 and outside the internal security surface 21. If it is determined, the process proceeds to step S44, and the control localizer 11 and the fixed localizer 12 analyze the waveform of the radio signal of communication outside the internal security surface 21.

  When a person exists between the localizers, the waveform of the radio signal exchanged between the localizers changes due to the influence of the human body. Therefore, the control localizer 11 and the fixed localizer 12 are controlled by the waveform analysis. The presence of a human body is detected between the fixed localizer 12 and the fixed localizer 12. The fixed localizer 12 that has detected the presence of the human body transmits the human body detection information in the following format to the control localizer 11 to notify the control localizer 11 of the detection of the human body.

Human body detection information:
(Own node number, partner node number, parameters indicating human body detection)
Here, the local node number and the counterpart node number can be a localizer ID. In addition, the local node number and the counterpart node number may be node numbers given at the time of registration in the network system, for example, indicating the order of registration.

  The human body detection information indicates that a human body is detected between the localizer indicated by the own node number and the localizer indicated by the counterpart node number. The detection parameter at that time may be a flag indicating the presence or absence of a human body or a parameter indicating the thickness of the human body.

  In this way, each fixed localizer 12 transmits human body detection information indicating the result of the analysis of the waveform of the radio signal to the control localizer 11.

  In step S45, the control unit 41 of the control localizer 11 is located inside the external warning surface 22 based on the human body detection information transmitted from each fixed localizer 12 or the result of detection of the human body of the control localizer 11 itself. Then, it is determined whether or not there is a person between the control localizer 11 and the fixed localizer 12 outside the internal warning surface 21 or between the fixed localizers 12.

  If it is determined in step S45 that there is no human being inside the external security surface 22 and between the control localizer 11 and the fixed localizer 12 outside the internal security surface 21 or between the fixed localizers 12, Proceeding to S46, the control unit 41 of the control localizer 11 determines whether or not another warning process has been executed.

  If it is determined in step S46 that no other warning process is being executed, the process returns to step S41 and the above-described process is repeated.

  If it is determined in step S46 that another warning process has been executed, the home warning process ends.

  In step S43, there is a difference between the generated inter-localizer distance matrix and the stored inter-localizer distance matrix for the control localizer 11 and the fixed localizer 12 that are inside the external security surface 22 and outside the internal security surface 21. Or in step S45, there is a person inside the external security surface 22 and between the control localizer 11 and the fixed localizer 12 outside the internal security surface 21 or between the fixed localizers 12. If it is determined that it has been illegally entered, the procedure proceeds to step S47.

  In step S47, the control unit 41 causes the wireless communication unit 50 to report the occurrence of abnormality to a predetermined report destination wirelessly. For example, the wireless communication unit 50 wirelessly reports the occurrence of an abnormality to a predetermined external communication device such as a mobile phone of a residence owner or a telephone of a security company.

  Furthermore, the presence of the unauthorized intruder 3 is informed to legitimate members such as the user 2-1 and the user 2-2 of the house 1 in the internal security surface 21 by the processing in steps S48 to S50, and the internal security surface 21. The unauthorized intruder 3 is less likely to approach. Furthermore, if possible, legitimate members such as the user 2-1 and the user 2-2 in the house 1 are evacuated in a direction far from the position of the unauthorized intruder 3.

  That is, in step S48, the control unit 41 of the control localizer 11 causes the white smoke generation module 49 or the white smoke generation module 79 of the fixed localizer 12 to eject white smoke.

  The white smoke generating module 49 or the white smoke generating module 79 heats a mixture of propylene glycol and water to about 200 ° C. to generate harmless white smoke on the human body and various devices. Thus, if a localizer in which the white smoke generating module 49 or the white smoke generating module 79 is built in advance is prepared, white smoke can be generated when the unauthorized intruder 3 is detected.

  For example, the control unit 41 of the control localizer 11 includes the control localizer 11 and the fixed localizer that have been determined that there is an element that causes a difference between the generated inter-localizer distance matrix and the stored inter-localizer distance matrix, or that there is a person. The position (range) of the unauthorized intruder 3 on the three-dimensional coordinate is specified from between the two and the fixed localizer 12. Then, the control unit 41 of the control localizer 11 selects the control localizer 11 or the fixed localizer 12 that is itself at a position close to the position of the unauthorized intruder 3 in the three-dimensional coordinates.

  The control unit 41 of the control localizer 11 causes the white smoke generation module 49 to eject white smoke when the control localizer 11 that is itself is selected.

  When the fixed localizer 12 is selected, the control unit 41 of the control localizer 11 causes the data communication unit to transmit a command for injecting white smoke to the selected fixed localizer 12 via the wireless transmission / reception unit 44. The command for ejecting white smoke includes, for example, a localizer ID unique to the selected fixed localizer 12.

  When a command for ejecting white smoke is transmitted via wireless, the control unit 71 of the fixed localizer 12 causes the wireless transmission / reception unit 74 to receive the command, and the data communication unit 76 includes the localizer ID included in the command. To extract. The control unit 71 of the fixed localizer 12 determines whether or not the extracted localizer ID is the same as its own localizer ID. When it is determined that the extracted localizer ID is the same as its own localizer ID, the control unit 71 of the fixed localizer 12 has transmitted a command to eject white smoke to itself. White smoke is ejected to the generation module 79.

  When it is determined that the extracted localizer ID is not the same as its own localizer ID, the control unit 71 of the fixed localizer 12 does not eject white smoke.

  In step S <b> 49, the control unit 41 of the control localizer 11 generates a warning sound on the speaker 48 or the speaker 78 of the fixed localizer 12.

  For example, the control unit 41 of the control localizer 11 includes the control localizer 11 and the fixed localizer that have been determined that there is an element that causes a difference between the generated inter-localizer distance matrix and the stored inter-localizer distance matrix, or that there is a person. The position (range) of the unauthorized intruder 3 on the three-dimensional coordinate is specified from between the two and the fixed localizer 12. Then, the control unit 41 of the control localizer 11 selects the control localizer 11 or the fixed localizer 12 that is itself at a position close to the position of the unauthorized intruder 3 in the three-dimensional coordinates.

  The control unit 41 of the control localizer 11 causes the speaker 48 to generate a warning sound when the control localizer 11 that is itself is selected.

  When the fixed localizer 12 is selected, the control unit 41 of the control localizer 11 causes the data communication unit to transmit a command for generating a warning sound to the selected fixed localizer 12 via the wireless transmission / reception unit 44. The command for generating the warning sound includes, for example, a localizer ID unique to the selected fixed localizer 12.

  When a command for generating a warning sound is transmitted via wireless, the control unit 71 of the fixed localizer 12 causes the wireless transmission / reception unit 74 to receive the command and causes the data communication unit 76 to include the localizer ID included in the command. To extract. The control unit 71 of the fixed localizer 12 determines whether or not the extracted localizer ID is the same as its own localizer ID. When it is determined that the extracted localizer ID is the same as its own localizer ID, the control unit 71 of the fixed localizer 12 has transmitted a command for generating a warning sound to itself. A warning sound is generated.

  The control unit 71 of the fixed localizer 12 does not generate a warning sound when it is determined that the extracted localizer ID is not the same as its own localizer ID.

  As described above, in step S48 and step S49, the fixed localizer 12 at the place where the intruder is detected (the fixed localizer 12 whose position on the coordinates has changed or the fixed localizer 12 that has detected a human body between other localizers). A warning voice is generated and white smoke is generated.

  As described above, the localizer that detects the human body, the localizer in which the position of the three-dimensional coordinate is changed, and the control localizer 11 are fixed by wireless communication so as to emit warning sound and generate white smoke only from the localizers around the localizer. A command (command) can also be sent to the localizer 12. Then, a warning sound and white smoke are generated in the vicinity where the intruder 3 has invaded and in the places where the intruder 3 moves. In other words, actuators that act to generate white smoke and actuators that act to generate warning sounds are spatially distributed to form a wireless communication network, depending on the location of the abnormality. This is a response as an actuator network system in which an actuator suitable for handling an abnormality in the system operates.

  As described above, the fixed localizer 12 outside the internal warning surface 21 and within a predetermined distance from the position where the unauthorized intruder 3 is present generates a warning sound and white smoke.

  When the distance between the mobile localizer 13 and the unauthorized intruder falls within a predetermined distance, the fixed localizer 12 closest to the unauthorized intruder may incorporate another repelling function and activate the repelling function. Other repelling functions include firing a tear spray or increasing the volume of a warning sound. Thereby, the legitimate member of the house 1 can be protected from the unauthorized intruder 3 who approaches the legitimate member of the house 1.

  In step S50, the control unit 41 of the control localizer 11 causes the speaker 48 or the speaker 78 of the fixed localizer 12 to generate an evacuation guidance sound.

  An authorized member of the house 1 inside the internal security surface 21 is notified of the presence of the unauthorized intruder 3 by a warning voice.

  For example, the control localizer 11 measures the distance to the moving localizer 13. In addition, the control localizer 11 transmits a command for causing each fixed localizer 12 to measure the distance from each fixed localizer 12 to the moving localizer 13. Each fixed localizer 12 measures the distance to the moving localizer 13 and transmits the measurement result to the control localizer 11.

  The control localizer 11 moves on a three-dimensional coordinate based on the information indicating the distance to the moving localizer 13 measured by itself and the distance from each fixed localizer 12 to the moving localizer 13 transmitted from each fixed localizer 12. The position of the localizer 13 is calculated.

  Then, the control unit 41 of the control localizer 11 selects the control localizer 11 or the fixed localizer 12 that is itself at a position close to the position of the moving localizer 13 in three-dimensional coordinates.

  When the control localizer 11 that is the control localizer 11 is selected, the control localizer 11 causes the speaker 48 to generate an evacuation guidance sound.

  When the fixed localizer 12 is selected, the control unit 41 of the control localizer 11 causes the data communication unit to transmit a command for generating an evacuation guidance voice to the selected fixed localizer 12 via the wireless transmission / reception unit 44. The command for generating the warning sound includes, for example, a localizer ID unique to the selected fixed localizer 12.

  When a command for generating an evacuation guidance voice is transmitted via wireless, the control unit 71 of the fixed localizer 12 causes the wireless transmission / reception unit 74 to receive the command, and the data communication unit 76 includes the command. The localizer ID is extracted. The control unit 71 of the fixed localizer 12 determines whether or not the extracted localizer ID is the same as its own localizer ID. When the control unit 71 of the fixed localizer 12 determines that the extracted localizer ID is the same as its own localizer ID, a command to generate an evacuation guidance voice has been transmitted to itself. An evacuation guidance sound is generated on the speaker 78.

  For example, the fixed localizer 12 that is within a predetermined distance from the mobile localizer 13 and is farthest from the unauthorized intruder 3 generates a sound (evacuation guidance sound) different from the warning voice. The legitimate member of the house 1 can move away from the unauthorized intruder 3 automatically by moving in a direction approaching the evacuation guidance sound.

  After the process of step S50, the procedure returns to step S41. As a result, the position of the unauthorized intruder 3 on the three-dimensional coordinates is repeatedly detected, and if the unauthorized intruder 3 is present in the external security surface 22, the step is performed based on the position of the unauthorized intruder 3 on the three-dimensional coordinates. The processing from S47 to step S50 is repeated.

  Next, details of the answering machine alert process will be described.

  FIG. 12 is a flowchart for explaining the details of the answering machine alert process corresponding to the process of step S10 of FIG.

  Since the processing of step S71 and step S72 is the same as the processing of step S41 and step S42 of FIG. 12, respectively, description thereof is omitted.

  In step S73, the control unit 41 of the control localizer 11 has a difference between the generated localizer distance matrix and the stored localizer distance matrix for the control localizer 11 and the fixed localizer 12 inside the external security surface 22. Determine whether or not.

  In the non-warning process, the stored inter-localizer distance matrix is updated to a value indicating the distance between the localizers at that time (when the non-warning process is executed). Accordingly, in step S73, the difference between the last updated localizer distance matrix and the current localizer distance matrix is detected. This difference is calculated as the sum of the absolute values of the differences for each corresponding element in the range where the distance can be measured in the stored inter-localizer distance matrix and the current inter-localizer distance matrix.

  If this sum exceeds a predetermined threshold value, the control unit 41 determines that there is a difference, that is, there is an abnormality. As shown in FIG. 1, if the fixed localizer 12 is attached to the window 4, the door 5, or the safe 6, the window 4 moves (opens) or the door 5 moves (opens). 4 and the distance between the localizer attached to the door 5 and another localizer changes. The same applies when the safe 6 moves. As a result, the inter-localizer distance matrix changes.

  If it is determined in step S73 that there is no difference between the generated localizer distance matrix and the stored localizer distance matrix for the control localizer 11 and the fixed localizer 12 inside the external security surface 22, the process proceeds to step S74. The control localizer 11 and the fixed localizer 12 analyze the waveform of the radio signal of communication inside the external security surface 22 by the same process as the process of step S44.

  In step S75, the control unit 41 of the control localizer 11 controls the control localizer inside the external warning surface 22 based on the human body detection information transmitted from each fixed localizer 12 or the detection result of the human body of the control localizer 11 itself. 11 is determined whether or not there is a person between the fixed localizer 12 and the fixed localizer 12.

  If it is determined in step S75 that there is no person between the control localizer 11 and the fixed localizer 12 inside the external security surface 22 or between the fixed localizers 12, the process proceeds to step S76, and the control unit of the control localizer 11 41 determines whether another warning process has been executed.

  If it is determined in step S76 that no other warning process is being executed, the process returns to step S71 and the above-described process is repeated.

  If it is determined in step S76 that another warning process has been executed, the home warning process ends.

  If it is determined in step S73 that there is a difference between the generated localizer distance matrix and the stored localizer distance matrix for the control localizer 11 and the fixed localizer 12 inside the external security surface 22, or in step S75 If it is determined that there is a person between the control localizer 11 and the fixed localizer 12 inside the external warning surface 22 or between the fixed localizers 12, the procedure proceeds to step S77 because it has been illegally intruded. .

  Since the processing from step S77 to step S79 is the same as the processing from step S47 to step S49 in FIG. 12, the description thereof is omitted.

  After the process of step S80, the procedure returns to step S71. As a result, the position of the unauthorized intruder 3 on the three-dimensional coordinates is repeatedly detected, and if the unauthorized intruder 3 is present in the external security surface 22, the step is performed based on the position of the unauthorized intruder 3 on the three-dimensional coordinates. The processes from S77 to S79 are repeated.

  FIG. 14 is a diagram illustrating the ejection of white smoke.

  In the example shown in FIG. 14, the security system includes a control localizer 11, a fixed localizer 12-1 to a fixed localizer 12-18, and a mobile localizer 13. The control localizer 11, the fixed localizer 12-1 to the fixed localizer 12-18, and the moving localizer 13 are arranged at various locations in the room 201-1 to the room 201-3 of the house 1 and outside the house 1.

  For example, the fixed localizer 12-4 is attached to the window 4-1. The fixed localizer 12-8 is attached to the window 4-2. The fixed localizer 12-16 is attached to the window 4-3.

  The fixed localizer 12-6 is attached to the door 5-1. The fixed localizer 12-1 and the fixed localizer 12-7 are attached to the door 5-2. The fixed localizer 12-11 is attached to the door 5-3. The fixed localizer 12-12 and the fixed localizer 12-13 are attached to the door 5-4.

  As shown in FIG. 14, when the window 4-1 of the house 1 is opened and the unauthorized intruder 3 illegally enters the room 201-1 of the house 1, the fixed localizer 12 attached to the window 4-1. -4 and the nearby fixed localizer 12-3 and fixed localizer 12-7, white smoke is ejected.

  That is, when an unauthorized intruder 3 enters through the window 4-1 of the room 201-1, an unauthorized intruder is located near the fixed localizer 12-4 whose position on the three-dimensional coordinate is moved by opening the window 4-1. 3 is present, the fixed localizer 12-4 attached to the window generates a warning sound and emits white smoke. White smoke is also emitted from the fixed localizer 12-3 and the fixed localizer 12-7 near the fixed localizer 12-4 attached to the window 4-1 of the room 201-1.

  In the home security process, a fixed localizer located near the mobile localizer 13 and away from the position of the unauthorized intruder 3 with respect to a legitimate member wearing the mobile localizer 13 located inside the internal security surface 21. The 12-15 and the fixed localizer 12-16 guide the evacuation in a direction away from the position of the unauthorized intruder 3 by outputting a sound.

  Next, a case where the present invention is applied to a car security system will be described with reference to FIG.

  The control localizer 11 is installed in an arbitrary place other than the door 301-1 to the door 301-4 in the passenger compartment of the vehicle 7. One or more fixed localizers 12 are installed inside each of the doors 301-1 to 301-4.

  For example, the fixed localizer 12-1 is installed inside the door 301-1, the fixed localizer 12-2 is installed inside the door 301-2, and the fixed localizer 12 is installed inside the door 301-3. -3 is installed, and the fixed localizer 12-4 is installed inside the door 301-4.

  A legitimate member who uses this vehicle 7 possesses the mobile localizer 13.

  The setting of the three-dimensional coordinate system, the setting of the positions of all the fixed localizers 12 on the three-dimensional coordinates, and the setting of the external security surface 22 are performed in the same manner as the processing described above.

  Thereafter, the car security system executes execution mode processing. The processing in the execution mode is the same as the processing described with reference to FIG. Since the internal security surface 21 is not set, the home security processing is not started (executed). Therefore, in the car security system, only two operations, the answering machine warning process and the non-warning process, are executed. The answering machine warning process and the non-warning process are the same as the process described with reference to FIG. 13 and the process described with reference to FIG. 11, respectively.

  In the answering machine warning process, if the fixed localizer 12 has a built-in speaker 78 for generating an alarm sound as an actuator and a white smoke generating module 79, any of the doors 301-1 to 301-4 can be used. When opened, the fixed localizer 12 emits a warning sound and generates white smoke in the passenger compartment.

  Thereby, even if it tries to intrude into the vehicle interior of the vehicle 7 illegally, the unauthorized intruder 3 does not have a view in the vehicle interior, and cheating is suppressed.

  As described above, according to the present invention, the warning process and the non-warning process can be automatically switched, so that the switching can be prevented from being forgotten and the security system can be prevented from malfunctioning.

  Further, the actuator operates according to the position of the unauthorized intruder, and the unauthorized intruder can be repelled.

  Further, it is possible to prevent an unauthorized intruder from approaching a legitimate member in the area, or to evade the legitimate member in the area while avoiding the unauthorized intruder. Further, it is possible to easily set and register a warning surface that needs to be set in order to automatically switch between a warning process and a non-warning process using the mobile localizer 13.

  As described above, the position of the legitimate member who uses the object is detected, the position of unauthorized intrusion into the object is detected, and the processing for unauthorized intrusion is executed by being arranged at multiple locations within the object. When the execution means for executing the process is selected and the execution of the process of the selected execution means is controlled according to the relationship between the position of the authorized member that has been detected and the position of the unauthorized intrusion detected Therefore, it is possible to execute a predetermined process for illegal intrusion according to the situation of the object to be alerted without requiring a troublesome operation.

  Detects the position of a legitimate member who uses the object, detects the position of unauthorized entry into the object, stores the position of the external warning plane, stores the position of the internal warning plane, and detects the position of the legitimate member detected Based on the above, when there is no legitimate member inside the external alert side, the first alert process is executed, and when there is a legitimate member inside the internal alert side, the first alert process is executed. When the execution of the first warning process or the second warning process is executed and the position of the unauthorized entry into the target is detected, the process for the unauthorized entry is performed. When it is executed, a troublesome operation is not required, and a predetermined process for unauthorized intrusion can be executed according to the situation of the target object to be warned.

  Send and receive information, send and receive signals modulated with a predetermined code, measure the distance to the device that is the partner of wireless transmission and reception, send and receive signals modulated with the code, communicate data with the device, illegal When predetermined processing for intrusion is executed and the entire control is performed, it is possible to detect unauthorized intrusion and execute predetermined processing for unauthorized intrusion.

  Measure the distance to the other party, detect the human body between yourself and the other party by analyzing the waveform of the wireless communication signal, and send the information indicating the distance to the other party or the information indicating the detection of the human body In this case, it is possible to detect unauthorized intrusion and execute predetermined processing for unauthorized intrusion.

  Measure the distance from yourself to each of the terminal devices, receive the information indicating the distance between the terminal devices that is transmitted from each of the terminal devices, and the distance from yourself to each of the terminal devices or the distance between the terminal devices When it is determined whether or not an object to be warned has been illegally intruded based on the above, it is possible to detect an unauthorized intrusion and execute a predetermined process for the unauthorized intrusion.

  The vehicle security system is installed on the inner surface of each door of the vehicle, and is held by a fixed terminal device that measures the distance from other fixed terminal devices and control terminal devices, and a person who has a legitimate authority to enter and exit the vehicle. It is composed of a mobile terminal device and a control terminal device installed inside the vehicle, and the position of the mobile terminal device is outside the external warning plane set by the fixed terminal device and the control terminal device installed in the vehicle. In some cases, the distance between the fixed terminal device and the control terminal device installed in the vehicle and the distance between the fixed terminal devices are monitored, and if the distance change satisfies a predetermined condition, it is determined that there is an abnormality. When it is determined that there is an abnormality, if a predetermined process for unauthorized intrusion is executed, the unauthorized intrusion can be detected and the predetermined process for unauthorized intrusion can be executed.

  The fixed node senses the surrounding environment, wirelessly communicates, applies an action to the outside, transmits information on the sensed surrounding environment to the control node, and operates the actuator in response to a command from the control node. Control, the control node performs wireless communication, selects a fixed node on which the actuator is to be operated based on information on the surrounding environment received from the fixed node, and transmits a command to operate the actuator to the selected fixed node In such a case, it is possible to detect an unauthorized intrusion and execute a predetermined process for the unauthorized intrusion.
