Abstract

PROBLEM TO BE SOLVED: To prevent an erroneous determination of an abnormal condition due to a mistaking a family member as an intruder when the family member comes home late or goes out during a stay-at-home watching mode in a security device for a general family. SOLUTION: When an away-from-home watching setting means 8 is operated during the stay-at-home watching mode set by operation of a stay-at-home watching setting means 6, a control part 2 sets a stay-at-home and away-from- home watching mode. In the stay-at-home and away-from-home watching mode, the control part 2 actuates an entrance/exit delay timer function. In this case, a covered watching area is the same as a covered area in the stay-at-home watching mode. Therefore, when one of family members is expected to come home late, another family member at home can go to bed after operating the stay-at-home watching setting means 6 and subsequently carrying out a predetermined operation in the away-from-home watching setting means 8. The family member comes back home late can release the stay-at-home and away-from- home watching mode by carrying out the predetermined operation in the away- from-home watching setting means 8 within an allowable time T even if he/she is detected by a wireless sensor WS.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device for general household use.

[0002]

2. Description of the Related Art In recent years, security devices have been installed in general homes to provide security. As one form of such a general household security device, a security device having a configuration as shown in FIG. 1 is known. One feature of the security device having the configuration shown in FIG. 1 is that the security status of the security area is switched from the security status to the release status, or the security status is switched from the release status to the security status by the security device body, and a special security status setting device is used. This is unnecessary, and in this regard, a security system can be constructed at low cost.

In FIG. 1, 1 is a security device, 2 is a control unit, 3 is a receiving unit, 4 is an area display unit, 5 is an LED, 6 is a home security setting unit, 7 is a cancellation unit, and 8 is an out-of-home warning setting unit. , 9 are speakers, 10 is a line controller, and WS is a wireless sensor. Here, a wireless wireless sensor is used as the sensor, but a conventionally well-known wired sensor may be used. When a wired sensor is used, a signal from each sensor is input to the control unit 2 via an appropriate interface.

[0004] The location of the wireless sensor WS is arbitrary, but is generally located indoors and outdoors. It is usually arranged indoors in each room, corridor, etc., and outdoors, outside the entrance, in a garden or the like. As the wireless sensor WS, a wireless hot-wire sensor that detects the movement of a person, a wireless open / close detection sensor that detects that a window or a door is opened, or the like can be used. Each wireless sensor WS is assigned a unique ID number. When the wireless sensor WS is a wireless hot-wire sensor, when detecting the movement of a person, the wireless sensor WS attaches an ID number assigned to itself and transmits an alarm signal indicating that the movement of the person has been detected. When the wireless sensor WS is a wireless open / close detection sensor, when detecting that a window or door has been opened, an ID number assigned to itself is assigned to indicate that the window or door has been opened. Transmit a notification signal. FIG.
When a plurality of wireless sensors WS are used, wireless transmission signals are different from each other.

[0005] The security device 1 is placed indoors. The configuration and operation of the security device 1 are as follows. Receiver 3
Receives the alarm signal wirelessly transmitted from the wireless sensor WS, and passes the received data to the control unit 2. The area display section 4 is provided with LEDs 5 of the number of guard areas that can be set in the security device 1. FIG. 1 shows a case where four LEDs 5 are provided, so that four warning areas can be set. The line control unit 10 is for reporting to a center device of a security company via a public telephone line.

[0006] The operation of the control unit 2 is as follows. First,
In the control unit 2, a correspondence table (not shown) between the guard area number and the ID number of the wireless sensor WS, which indicates in which guard area the ID number of the wireless sensor WS is arranged, is registered. ing. The control unit 2 is set with three operation modes: a home security mode, a release mode, and an outside security mode.

[Home security mode] The home security mode is an operation mode mainly set while sleeping. That is, although there is a possibility that a person may move indoors even while sleeping, the wireless sensor W
Even if an alarm signal is received from S, it cannot be determined that an abnormal situation has occurred. However, when a person is intruded into the garden or a person is standing at the entrance, some measures need to be taken, and it is preferable that an abnormal situation occurs.

The home security mode is provided for this purpose, and the home security mode can be entered by operating the home security setting means 6. The home alert setting means 6 may be constituted by a push button switch. With a push button switch, the home alert mode can be easily entered by a simple one-touch operation of pressing the button, and the operability is good.

When detecting that the home security setting means 6 has been operated, the control unit 2 controls only the security area set in advance to perform security in the home security mode, such as a security area set outdoors. Immediately, and the other alert areas are not alerted.
Then, the control unit 2 instructs the area display unit 4 to turn on the LED 5 corresponding to the security area, which is set in advance so as to perform security in the home security mode.

In the home security mode, the control unit 2
Receives an alarm signal from the wireless sensor WS, and if the wireless sensor WS is located in a security area other than a preset security area that is set to be alert in the home security mode, the alarm signal is Is ignored, but if the wireless sensor WS that has transmitted the alarm signal is located in a security area that is set in advance so as to perform security in the home security mode, it is determined that an abnormal situation has occurred. Then, the speaker 9 emits a sound indicating the occurrence of an abnormality such as a siren sound or a buzzer sound. As a result, it is possible to notify the sleeping family of the occurrence of the abnormality, and to threaten the intruder when the speaker 9 is installed outdoors. At this time, the control unit 2
Sends the data of the abnormality report and the telephone number of the center device to the line control unit 10 to give a report. Thereby, the abnormality notification is made to the center device of the security company.

[Release Mode] This release mode is an operation mode for releasing the home security mode. The release mode is
The setting can be made by operating the release means 7. The release means 7 may be constituted by a push button switch. With a push button switch, the home alert mode can be easily released by a simple one-touch operation of pressing the button, and the operability is good. Control unit 2
Detects that the release means 7 has been pressed, cancels the home security mode set up to that time, and displays on the area display unit 4 the LED 5 that was lit during the home security mode.
Is turned off. Then, in the release mode, the control unit 2 ignores the alarm signal from any wireless sensor WS even if it receives the alarm signal. That is, the release mode is a mode in which no warning is performed for all the warning areas.

[Outgoing caution mode] This outgoing caution mode is an operation mode set when all the family members go out and become unmanned. When unmanned, it is necessary to detect intruders not only outdoors but also indoors,
In this outing alert mode, an alert state is set for all alert areas. Therefore, when the out-of-office alert mode is set, the control unit 2 turns on the LEDs 5 of all the alert areas on the area display unit 4.

Since the security device 1 is placed indoors, if the entire security area is immediately placed in a security state when the outside security mode is set by a family member, the indoor wireless sensor WS is required before the family member goes outdoors. And it is determined that an abnormal situation has occurred.

Therefore, when the out-of-office alert mode is set, the control unit 2 does not immediately put the entire alert area into the alert state, but detects that the out-of-office alert setting means 8 is operated, and outputs the out-of-office alert mode. When the predetermined grace period T elapses from the start, all the guard areas are set to the guard state. Therefore, after the control unit 2 enters the outside warning setting means 8 and before the grace period T elapses, the wireless sensor W
The control unit 2 ignores the alarm signal even if it receives the alarm signal from S.
Further, in the state where the vehicle is in the out-of-office warning mode, the control unit 2 does not immediately determine that an abnormal situation has occurred even when receiving the alarm signal from the wireless sensor WS, and receives the alarm signal from the wireless sensor WS. After that, if the out-of-office mode is released before the predetermined grace time T elapses, the out-of-office mode is immediately released, the alarm signal is ignored, and the out-of-office mode is released. If the grace period T elapses without any change, it is determined that an abnormal situation has occurred. Such a function is called an entry / exit delay timer function.

The grace period T can be arbitrarily determined, but may be set in consideration of the distance from the entrance to the security device 1 or the like. However, if the grace time T is set too long, there is a possibility that the pirate may intrude and move around during that time.

Therefore, when all the family members go out, the outside warning mode is set by the outside warning setting means 8, and all the members may go outside during the grace period T. When the control unit 2 detects that the predetermined operation has been performed by the outside warning setting unit 8, the control unit 2 enters the outside warning mode and instructs the area display unit 4 to turn on the LEDs 5 in all the warning areas. Until the grace period T elapses, the alarm signal from the wireless sensor WS is ignored, and after the grace period T elapses, all the guard areas are set in the alert state. Further, when the family member returns home, the detection may be detected by the wireless sensor WS arranged outdoors, but the out-of-out warning mode may be canceled within the grace period T from that point.

The operation when it is determined that an abnormal situation has occurred is the same as described above. The control unit 2 makes the speaker 9 emit a sound indicating the occurrence of the abnormality, and the line control unit 1
The data of the abnormality report and the telephone number of the center device are passed to 0 to issue a report. Thereby, the abnormality notification is made to the center device of the security company.

The setting and release of the out-of-office alert mode are performed by operating the out-of-office alert setting means 8. However, this out-of-office alert setting means 8 cannot be operated by one touch like a push button switch. Must be able to perform the operation to enter the outside warning mode and the operation to cancel it. This is because, for example, if a push button switch is used as the out-of-office setting means 8, a thief can intrude, and the out-of-office mode can be easily released by pressing the push-button switch.

In order to set and release the out-of-office warning mode, it is general to perform a predetermined operation using a specific device. As the method, for example, a method of using a lock as the out-of-office security setting means 8 and rotating the lock using a key that matches the lock, or a method of using a ten-key as the out-of-office security setting means 8 and using the numeric keypad to control the Or using a magnetic card reader or an IC card reader as the out-of-office setting means 8 and inserting a magnetic card or an IC card in which a password registered in the control unit 2 is stored in advance. In addition, a non-contact type automatic identification code reader (RFID (Rsdio Frequency Identification) reader) for transmitting an interrogation radio wave is used as the out-of-home warning setting means 8, and a password registered in the control unit 2 in advance is used. The stored ROM was connected to one end of the antenna coil,
A method of bringing a so-called on-chip coil type non-contact information storage medium close to an RFID reader has been adopted. Since the RFID reader and the non-contact information storage medium of the on-chip coil type are well known, detailed description will be omitted.

For example, now, the out-of-office setting means 8 is RF
Assuming that the device is constituted by an ID reader, when the out-of-office warning mode is set, the non-contact information storage medium is
What is necessary is just to approach D reader. At this time, the non-contact information storage medium is generated by the interrogation radio wave from the RFID reader,
The personal identification number stored in the ROM is transmitted from the antenna coil. The RFID reader receives this and notifies the control unit 2 of the received personal identification number. The control unit 2 is RFI
Judge whether the security code received from the D-reader is registered in advance or not. If it is not registered in advance, ignore it. If it is registered, go out. Enter mode. The operation of the entry / exit delay timer function at this time is as described above.

The release of the out-of-office warning mode cannot be performed by the release means 7, but a predetermined operation must be performed by the out-of-office setting means 8. For example, as described above, when the out-of-office setting means 8 is configured by an RFID reader, when releasing the out-of-office alert mode, an operation of bringing the non-contact information storage medium closer to the RFID reader is performed. At this time, the non-contact information storage medium is generated by the interrogation radio wave from the RFID reader, and transmits the personal identification number stored in the ROM from the antenna coil. The RFID reader receives this and notifies the control unit 2 of the received personal identification number. The control unit 2 determines whether or not the password received from the RFID reader has been registered in advance. If the password has not been registered in advance, the controller 2 ignores the password and continues the outside warning mode. If so, release the out-of-office alert mode. The operation of the entry / exit delay timer function at this time is also as described above.

As described above, when the out-of-office warning mode is set, and when the out-of-office warning mode is released, it is necessary to perform a predetermined operation by the out-of-office warning setting means 8. However, in the present invention, how to set and cancel the out-of-office alert mode is not an essential matter, and is simply referred to as operating the out-of-office alert setting means 8 or the like.

[0023]

However, the conventional security device as described above has the following problems. Now, suppose that one of the family members came home late. At this time, at least one of the householders at home cannot go to bed and must be awake without setting the home alert mode. This is because if all the householders at home go to bed, at that time the home alarm setting means 6
To set the home alert mode. At this time, only a predetermined warning area such as an outdoor warning area is in a warning state, and if the wireless sensor WS in the warning area transmits an alarm signal, the control unit 2 immediately determines that an abnormal situation has occurred. So, the person who came home late was
If detected by the wireless sensor WS disposed in the alert area in the alert state, a sound notifying the occurrence of an abnormality sounds from the speaker 9, and the abnormality is notified to the center device of the security company. However, it is not desirable that such a situation occur.

Conversely, there is a case in which all the family members are at home and one wants to go out for some business after pressing the home security setting means 6 to set the home security mode. Or, when the user goes out, if the wireless sensor WS disposed in the guard area that is in the guard state during the home guard mode detects the wireless sensor WS, the controller 2 immediately determines that an abnormal situation has occurred. . It is not desirable that such a situation occur.

Accordingly, the present invention provides a security device that can prevent an abnormal situation from occurring when returning home when the home security mode is set or when going out when the home security mode is set. The purpose is to provide.

[0026]

In order to achieve the above object, a security device according to the present invention provides a home security mode for setting a home security mode in which only a predetermined security area is immediately in a security state. Setting means, a release means for setting a release mode for releasing the home security mode, and an outgoing alert setting for setting an outgoing alert mode in which all of the guard areas are in the alert state while operating the entry / exit delay timer function. Means, a security device comprising a control unit,
The control unit, in a state where the home alert setting means is operated and the home alert mode has been entered, and detects that a predetermined operation has been performed by the out-of-home alert setting means, sets the security state in the home alert mode. It is characterized in that a warning state is set only for the warning area determined as described above, and an entry / exit delay timer function is operated.

[0027]

Embodiments of the present invention will be described below. The configuration of the security device according to the present invention is the same as that shown in FIG. 1, but the operation is different. Hereinafter, differences in the operation will be described.

When a predetermined operation determined by the out-of-home alert setting means 8 is performed in a state in which the at-home alert mode is set, the control unit 2 enters a new operation mode of the at-home / out-of-home alert mode. . In the at-home / out-of-home warning mode, the control unit 2 operates the entry / exit delay timer function. The guard area that is set in the guard state in the home / out-of-home guard mode is the same as in the home guard mode, and is the only guard area that is set in advance to perform security in the home-care mode. Not all guard areas are alerted.

Therefore, the control unit 2 sets only the preset guard area to the guard state from the point in time when the grace period T has elapsed since entering the home / out-of-home guard mode. Further, in the home / out-of-home warning mode, the control unit 2 does not immediately determine that an abnormal situation has occurred even if it receives an alarm signal from the wireless sensor WS, and the wireless sensor WS
After receiving the alarm signal from, the in-home / out-of-home warning mode is not canceled, and only when the grace period T elapses, it is determined that an abnormal situation has occurred.

The release of the in-home / out-of-home warning mode can be performed only by performing a predetermined operation by the out-of-home warning setting means 8. That is, when the out-of-office setting means 8 detects that a predetermined operation is performed in the at-home / out-of-home alert mode, the control unit 2 immediately returns to the in-home alert mode. When returning to the home security mode, the control unit 2 releases the entry / exit delay timer function.

Therefore, if only one person comes home late, the resident at home first operates the home security setting means 6, then performs a predetermined operation with the outside security setting means 8, and then goes to bed. be able to. At this time, the control unit 2
First, it is detected that the home security setting means 6 has been operated, and the operation enters the home security mode. Thereafter, the out-of-home security setting means 8 detects that a predetermined operation has been performed, and enters the home / out-of-home security mode. Therefore, the person who has returned home may be detected by the wireless sensor WS disposed in the guarded area in a guarded state, but even if it is detected, a predetermined operation is performed by the out-of-office warning setting means 8 within the grace period T. , The home / out-of-home warning mode can be canceled. Then, at this time, the control unit 2 immediately cancels the home / out-of-home alert mode and returns to the home alert mode, so that the alarm signal from the wireless sensor WS is ignored and it is not determined that an abnormal situation has occurred.

When the user wants to go out while in the home security mode, the outside security setting means 8 performs a predetermined operation. At this time, the control unit 2 enters the at-home / out-of-home warning mode and operates the entry / exit delay timer function, so that the person who is going out may go out within the grace period T.

As described above, according to this security device, when returning home is delayed, or when going out in the home security mode, the family member is erroneously determined to be an intruder, and an abnormal situation occurs. A situation can be avoided.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, as described above, the sensor is not limited to the wireless sensor, and a wired sensor may be used.
