It is a flow chart which shows an example of a processing procedure in a position information server which constitutes a position information system of an embodiment.

Hereinafter, an embodiment of a position information system to which the present invention is applied will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a schematic configuration of a position information system 1 according to the present embodiment.
The position information system 1 of the present embodiment can receive signals (radio waves) from beacons (transmitting terminals) 10 disposed at a plurality of locations in a predetermined area inside a building, for example, as shown in FIG. A mobile terminal 20, a location information server 40 for performing data communication with the mobile terminal 20 via a mobile phone base station 30 and a communication network N such as the Internet, and a plurality of locations in a predetermined area inside the building Data communication is performed between the fire receiver 60 capable of receiving the fire detection signal from the fire detector 50 and the fire receiver 60 via a gateway (relay) 70 and a communication network N such as the Internet. It comprises a fire information server 80 and the like.

  The communication method of the beacon 10 for transmitting a wireless signal (specific information such as a device ID and facility information) to the portable terminal 20 includes, for example, Bluetooth (registered trademark) communication, a wireless LAN such as WiFi according to the IEEE 802.11 standard, and the like. A known communication method such as infrared communication can be used. The interval at which the beacons 10 are arranged is not particularly limited, but in the following description, it is assumed that the beacons 10 are arranged at a distance such that the communication ranges of the adjacent beacons 10 overlap with each other.

More specifically, since the fire detector 50 and the sprinkler head are originally installed at predetermined intervals in the building, the beacon 10 attached to the device in a form built in or added thereto, or the device The beacon 10 attached in the form of being installed in the vicinity of can be used.
The beacon 10 includes a transmitting unit that periodically transmits information on power supply (built-in battery information or external power supply information) and its own identification information to the surroundings via a radio signal. The signal transmitted by the beacon 10 wirelessly (beacon signal) only needs to include at least the identification information of the beacon 10, and may further include information on the area where the beacon 10 is installed.

  The mobile terminal 20 is a device such as a smartphone having a receiving function of receiving a signal from the beacon 10 and a wireless communication function. The mobile terminal 20 periodically receives a beacon signal wirelessly transmitted from the beacon 10, extracts identification information (identification code) and the like included in the beacon signal, and detects the received radio wave intensity of the beacon signal. Transmitting the beacon information including the identification information and the received radio wave intensity to the position information server 40 via the mobile phone base station 30 and the communication network N; and transmitting the beacon information via the communication network N and the mobile phone base station 30 An application program (location information display application) for executing a process of displaying a floor diagram image based on the floor diagram information transmitted from the location information server 40 on a screen is stored. When the mobile terminal 20 receives a beacon signal transmitted from a plurality of beacons 10 (beacons 10 whose communication ranges overlap each other), the mobile terminal 20 transmits each beacon information to the position information server 40.

  When detecting the occurrence of an abnormal phenomenon such as heat, smoke, flame, and harmful gas, the fire detector 50 transmits a fire detection signal to the fire receiver 60 via the detector line 51. The fire detector 50 may be of a type that adds its own installation address to a fire detection signal, or may be a type of sensor that does not add its own installation address to a fire detection signal.

When receiving the fire detection signal from the fire detector 50, the fire receiver 60 displays a fire notification on the display unit and performs control such as ringing of a district bell and smoke prevention and smoke emission. Further, the fire receiver 60 transmits fire information including fire occurrence location information and occurrence time information to the fire information server 80 via the gateway 70 and the communication network N.
In addition, when the installation address of the fire detector 50 is added to the fire detection signal, the fire receiver 60 specifies a fire occurrence location based on the installation address. On the other hand, if the installation address of the fire detector 50 is not added to the fire detection signal, the location of the fire occurrence is specified based on the detector line 51 (warning zone) that transmitted the fire detection signal.

  The fire information server 80 includes, for example, as shown in FIG. 1, a database 81 that stores equipment / equipment information of each building managed by the fire information server 80. Here, the equipment / equipment information of the building includes a display / non-display table regarding whether or not items such as equipment / equipment installed on each floor of the building are displayed on the floor diagram, This is information including the installation position information of items such as equipment and devices installed on the floor.

In the display / non-display table, as shown in FIG. 2A, for example, partitions, room names, doorways, doors, equipment for moving between various floors (for example, stairs, elevators, escalators), and various disaster prevention-related equipment and devices. (For example, emergency exits, fire alarm equipment (e.g., transmitters for district bells, etc.), fire extinguishing equipment (fire extinguishers, fire hydrants, etc.), emergency telephones, smoke control equipment (fire doors, fire shutters, smoke outlets, etc.)) Whether or not the item is displayed during a normal time, not during a fire, whether or not to display when a fire has occurred on the same floor, and whether or not to display when a fire has occurred on another floor are stored. I have.
FIG. 2A shows a display / non-display table of the building Z among the display / non-display tables of the buildings managed by the fire information server 80. The floor plan image displayed during the normal time as the floor plan image of the building Z displays symbols, characters, and the like (hereinafter, simply referred to as “symbols, etc.”) indicating partitions, room names, stairs, elevators, and transmitters. It has become. In the building Z, at least a transmitter, an emergency exit, a fire extinguisher, a fire hydrant, an emergency telephone, and a fire door are installed as disaster prevention-related facilities and equipment.

When receiving the fire information from the fire detector 50, the fire information server 80 can execute a process of transmitting the fire information to the position information server 40 via the communication network N.
Further, the fire information server 80 specifies a building in which a fire has occurred based on the fire information, and acquires equipment / equipment information of the specified building from the database 81. Then, based on the acquired equipment / device information, item information that does not need to be displayed at the time of fire that specifies items that are displayed during normal times but is not displayed during a fire, and information that does not display during normal times but specifies items that are displayed during a fire are required. A process of generating item information and transmitting the generated information to the location information server 40 via the communication network N can be executed.

For example, as in the example shown in FIG. 2A, in the building Z, items that are displayed during normal times but are not displayed when a fire occurs on the same floor (hereinafter referred to as “items not required to be displayed during a fire on the same floor”) are elevators. Items that are normally displayed but not displayed when a fire occurs on another floor (hereinafter referred to as "other floor fire display unnecessary items") are elevators and transmitters. Therefore, when a fire occurs in the building Z, the fire information server 80 stores information specifying the elevator as a fire-unnecessary item on the floor and information on the elevator on the floor (the floor on which the fire occurs). No fire display including information on the installation position, information specifying the elevator and transmitter as items not required for fire on another floor, and information on the installation position of the elevator and transmitter on another floor (floor where no fire has occurred) Generate item information.
The items not required to be displayed at the time of the fire on the floor and the items not required to be displayed at the time of another floor are preferably, for example, equipment / equipment that should not be used in the event of a fire or equipment that is confusing to be displayed when performing a fire initial operation.

As shown in FIG. 2A, in the building Z, items that are not normally displayed but are displayed when a fire occurs on the same floor (hereinafter, “items required to be displayed when the floor is fired”) include an emergency exit and fire extinguishing. Items that are a fire extinguisher, a fire hydrant, an emergency telephone, and a fire door, which are not normally displayed but are displayed when a fire is fired on another floor (hereinafter, “items required to be displayed at another floor fire”) are emergency exits and fire doors. Therefore, when a fire has occurred in the building Z, the fire information server 80 sets information indicating an emergency exit, a fire extinguisher, a fire hydrant, an emergency telephone, and a fire door as items required to be displayed during a fire on the floor, and Information on the location of emergency exits, fire extinguishers, fire hydrants, emergency telephones and fire doors on the floor where the fire has occurred, and information specifying emergency exits and fire doors as items required to be displayed during a separate floor fire, On the floor where no fire has occurred, information on the items required to be displayed at the time of fire, including information on the installation position of the emergency exit and fire doors is generated.
The items required to be displayed at the time of a fire on the floor are preferably, for example, facilities and equipment necessary for the initial operation of the fire such as evacuation, fire extinguishing work, and fire notification. Further, it is preferable that the items required to be displayed at the time of another floor fire are, for example, facilities and equipment necessary for evacuation.

  The position information server 40 includes, for example, a database 41 that stores map information of each building managed by the position information server 40, as shown in FIG. Here, the building map information is information including a floor plan of each floor (each floor) of the building, identification information of the beacon 10 installed on each floor of the building, installation position information, and the like.

  When receiving the beacon information from the mobile terminal 20, the position information server 40 calculates the current position of the mobile terminal 20 based on the received beacon information and the information stored in the database 41. Then, a floor map of the floor where the portable terminal 20 is located is extracted from the database 41, the current position of the portable terminal 20 is plotted on the extracted floor map, and floor map information is generated. Is transmitted to the mobile terminal 20 via the communication network N and the mobile phone base station 30. Thereby, the floor map image indicating the current position of the mobile terminal 20 is displayed on the mobile terminal 20.

Specifically, when the building where the mobile terminal 20 is located is the building Z, and the floor where the mobile terminal 20 is located is the 10th floor, the screen of the mobile terminal 20 is displayed on the screen of FIG. A floor view image as shown in (b) is displayed. In the example shown in FIG. 2B, a symbol indicating the current position of the mobile terminal 20 is added between the store F and the store J.
In addition, as shown in FIG. 2A, in the building Z, partitions, room names, stairs, elevators, and transmitters are set as items to be displayed during normal times when no fire occurs. In the example shown in FIG. 2B, symbols indicating these items are also added. In the present embodiment, it is assumed that a floor plan to which symbols indicating items to be displayed in normal times are added in advance is stored in the database 41.

  Further, when the position information server 40 receives the fire information (information including fire occurrence location information), the fire display required item information, and the fire display unnecessary item information from the fire information server 80, the position information server 40 receives these information. It is possible to execute processing for generating floor plan information reflecting the information and transmitting the generated floor plan information to the mobile terminal 20 via the communication network N and the mobile phone base station 30. Thereby, the portable terminal 20 is a floor plan image showing the current position of the portable terminal 20, and is a floor plan image reflecting fire information, fire-necessary display item information, and fire-necessary display unnecessary item information. Is displayed.

  Specifically, it is a case where a fire has occurred in the store B on the 10th floor of the building Z, where the building where the mobile terminal 20 is located is the building Z and the floor where the mobile terminal 20 is located Is the same floor (that is, the tenth floor), a floor map image as shown in FIG. 3A is displayed on the screen of the portable terminal 20. In the example illustrated in FIG. 3A, a sign indicating the current position of the mobile terminal 20 is added between the store F and the store J, and a sign indicating the fire occurrence position is added to the store B. ing.

In addition, as shown in FIG. 2A, in the building Z, items required to be displayed at the time of a fire on the floor are an emergency exit, a fire extinguisher, a fire hydrant, an emergency telephone, and a fire door. Therefore, in the example shown in FIG. Are added. As a result, the position of the disaster prevention-related facilities and equipment can be notified, so that quick evacuation, fire extinguishing work, and fire notification can be performed.
In addition, as shown in FIG. 2A, in the building Z, the item that does not need to be displayed in the event of a fire on the floor is an elevator. Therefore, in the example shown in FIG. 3A, symbols indicating the elevator are deleted. Thereby, use of an elevator that should not be used in the event of a fire can be avoided.
Further, as shown in FIG. 2 (a), in the building Z, the disaster prevention-related equipment and devices which are displayed both at normal times and at the time of a fire on the same floor are transmitters, and in the example shown in FIG. The symbol or the like indicating the transmitter has changed to a symbol or the like indicating the item required to be displayed at the time of the floor fire. That is, the symbol indicating the transmitter or the like has changed from a symbol not including a thick frame (see FIG. 2B) to a symbol including a thick frame (see FIG. 3A).

On the other hand, in the case where a fire has occurred in the store B on the 10th floor of the building Z, the building where the mobile terminal 20 is located is the building Z, and the floor where the mobile terminal 20 is located is another floor. In the case of (for example, the ninth floor), for example, a floor diagram image as shown in FIG. 3B is displayed on the screen of the portable terminal 20. In the example shown in FIG. 3B, a symbol or the like indicating the current position of the mobile terminal 20 is added between the store R and the store V.
Also, as shown in FIG. 2 (a), the items required to be displayed at the time of another floor fire in the building Z are emergency exits and fire doors. Therefore, in the example shown in FIG. 3 (b), symbols indicating these items are added. Have been. Further, as shown in FIG. 2A, the items not required to be displayed at the time of another floor fire in the building Z are an elevator and a transmitter, so in the example shown in FIG. 3B, the symbols indicating these items are deleted. ing. From these, quick and appropriate evacuation becomes possible.

  In the examples shown in FIGS. 3A and 3B, symbols indicating items designated by the fire-unnecessary display item information (items on the same floor that do not need to be displayed at the time of the floor, items not required to be displayed at the time of another floor) are deleted. However, the present invention is not limited to this. For example, as shown in FIG. It may be displayed in a lighter display than usual (dotted line display, blur display, etc.). In the example shown in FIG. 4, symbols indicating elevators, which are items that do not need to be displayed in the event of a fire on the floor, are indicated by dotted lines. The display mode different from the normal mode is not limited to shading, but may be a color, a size, a shape, the presence or absence of blinking, and the like.

In addition, disaster prevention-related facilities / equipment includes facilities / equipment that can be operated by ordinary people (persons other than specific persons such as building managers and firefighters) in the event of a fire (hereinafter referred to as “operable equipment / equipment”). Is included. Therefore, in order to notify the position of the operable equipment / equipment to the general person carrying the portable terminal 20, the operable equipment / equipment among the symbols indicating the items designated by the fire-required display required item information is referred to. The symbol or the like may be displayed so as to be identifiable. In the example shown in FIG. 4, symbols such as emergency telephones, fire extinguishers, and fire hydrants, which are operable facilities and equipment, are hatched as highlighted.
Operable facilities and equipment are not limited to emergency telephones, fire extinguishers and fire hydrants. In building Z, the emergency telephone, fire extinguisher and fire hydrant can be operated by ordinary people, and the fire door can be operated only by a specific person. Therefore, in the example shown in FIG. Fire doors are not highlighted while highlighted. That is, when a fire has occurred in a building where ordinary people can operate the fire door, a symbol or the like indicating the fire door may be highlighted in the floor plan image of the building.

Also, by distinguishing ordinary people and specific people, items that need to be displayed at the time of fire on the same floor, items that need to be displayed at the time of another floor, items that do not need to be displayed at the same time, and items that do not need to be displayed at the time of another floor are set. good. That is, for example, whether the user of the mobile terminal 20 that has downloaded the application is a general person or a specific person is set in the position information display application, and the position information server 40 The portable terminal 20 set to be a general person is provided with a symbol or the like indicating a fire display required item for a general person, and a symbol or the like indicating a fire display unnecessary item for a general person. The floor map information for displaying the erased floor map image is transmitted, and the symbol indicating the fire display required item for the specific person is displayed on the mobile terminal 20 in which the user is set as the specific person. Floor map information for displaying a floor map image that has been added and in which a symbol indicating a display unnecessary item for a specific person at the time of fire has been deleted may be transmitted.
In addition, operable facilities / equipment may be set by distinguishing a general person from a specific person.

  Further, when the user touches a portion on the screen of the mobile terminal 20 on which the floor plan image is displayed, on which a symbol or the like indicating an operable facility / equipment (for example, a symbol with a highlighted display) is displayed. Information about possible facilities / equipment (for example, equipment information or operation method of operable facilities / equipment) may be displayed. That is, in the map image (floor diagram image) displayed on the screen of the mobile terminal 20, one of the predetermined display-required facilities / equipment (the same floor fire display required item and another floor fire display required item) is selected. In such a case, information on the selected facility / equipment may be displayed on the screen. As a result, even a general person who is not familiar with the use of the operable equipment / equipment can perform an appropriate fire extinguishing operation, thereby preventing fire spread.

  Next, a processing procedure by the portable terminal 20, the fire information server 80, and the position information server 40 constituting the position information system 1 of the present embodiment will be described with reference to flowcharts shown in FIGS.

<Mobile terminal>
When the location information display application is activated, the mobile terminal 20 first determines whether a beacon signal transmitted from the beacon 10 has been received, for example, as illustrated in FIG. 5A (step S11). If a beacon signal has been received (step S11; Yes), beacon information including the identification information of the beacon 10 included in the beacon signal and the received radio wave intensity of the beacon signal are transmitted to the mobile phone base station 30 and The information is transmitted to the position information server 40 via the communication network N (step S12).
Next, it is determined whether the floor plan information transmitted from the position information server 40 has been received (step S13). Then, when the floor plan information is received (Step S13; Yes), a floor plan image based on the floor plan information is displayed on the screen (Step S14). Thus, in the first step S14 after the start of the location information display application, the latest floor plan image is displayed on the screen of the mobile terminal 20, and after the start of the location information display application, in the second and subsequent steps S14, The floor plan image currently displayed on the screen is updated to the latest floor plan image.

<Fire information server>
For example, as shown in FIG. 5B, the fire information server 80 first determines whether or not fire information (information including fire occurrence location information and occurrence time information) transmitted from the fire receiver 60 has been received. (Step S21). Then, when the fire information is received (Step S21; Yes), the fire information is transmitted to the position information server 40 via the communication network N (Step S22).

Next, the building in which the fire has occurred is specified based on the fire information, the equipment / equipment information of the specified building is acquired from the database 81, and the item information required for fire display is acquired based on the acquired equipment / equipment information. The generated and displayed fire required item information is transmitted to the position information server 40 via the communication network N (step S23). Next, it generates fire-necessary display unnecessary item information based on the acquired facility / equipment information, and transmits the generated fire-necessary display unnecessary item information to the position information server 40 via the communication network N (step S24).
If the building in which the fire has occurred does not have the same floor fire display item and another floor fire display item, the processing in step S23 is omitted. If there is no display unnecessary item at the same floor and no display unnecessary item at another floor in the building where the fire has occurred, the process of step S24 is omitted.

<Location information server>
For example, as shown in FIG. 6, the position information server 40 first determines whether beacon information transmitted from the mobile terminal 20 has been received (step S31). When the beacon information is received (Step S31; Yes), the current position of the mobile terminal 20 is calculated based on the received beacon information and the information stored in the database 41 (Step S32). A floor map of the floor where the portable terminal 20 is located is extracted from 41, and the current position of the portable terminal 20 is plotted on the extracted floor map to generate floor map information (step S33). That is, in step S33, floor diagram information for displaying a floor diagram image to which a symbol indicating the current position of the mobile terminal 20 is added is generated.

Next, it is determined whether a fire has occurred in the building where the portable terminal 20 is located (step S34). The location information server 40 determines whether a fire has occurred in the building where the portable terminal 20 is located, for example, by inquiring of the fire information server 80 via the communication network N. Alternatively, when fire information transmitted from the fire information server 80 and relating to the building where the portable terminal 20 is located is received, a fire occurs in the building where the portable terminal 20 is located. It is determined that there is.
If no fire has occurred in the building where the mobile terminal 20 is located (step S34; No), the floor plan information generated in step S33 is transmitted via the communication network N and the mobile phone base station 30. The data is transmitted to the portable terminal 20 (step S42). Thereby, for example, a floor plan image as shown in FIG. 2B is displayed on the screen of the mobile terminal 20.

  On the other hand, if a fire has occurred in the building where the portable terminal 20 is located (step S34; Yes), the fire-related information (fire information, display during fire) relating to the building where the portable terminal 20 is located is located. It is determined whether necessary item information (item information unnecessary for fire display) has been received (step S35). Then, when the fire related information regarding the building where the portable terminal 20 is located is received (Step S35; Yes), the fire occurrence position is specified based on the fire related information, and the portable terminal 20 is located. It is determined whether a fire has occurred on the floor where the fire is occurring (step S36).

  If a fire has occurred on the floor where the portable terminal 20 is located (step S36; Yes), the fire occurrence position is plotted on the floor diagram where the current position of the portable terminal 20 is plotted. (Step S37), the installation positions of the items required to be displayed at the time of the floor fire are plotted (Step S38). Next, from the floor diagram in which the current position of the portable terminal 20, the fire occurrence position, and the installation position of the floor fire display required items are plotted, the floor fire display unnecessary items are deleted (step S39). That is, in steps S37 to S39, using the floor diagram information generated in step S33, a symbol or the like indicating the fire occurrence position and a symbol or the like indicating the item required to be displayed at the time of the floor fire are added, and the floor fire information is added. Floor map information for displaying a floor map image from which symbols indicating time display unnecessary items have been deleted is generated.

Then, the floor plan information generated in steps S37 to S39 is transmitted to the mobile terminal 20 via the communication network N and the mobile phone base station 30 (step S42). Thereby, for example, a floor plan image as shown in FIG. 3A is displayed on the screen of the mobile terminal 20.
If the fire-required display item information has not been received as the fire-related information, the process of step S38 is omitted. In addition, when the fire-unnecessary display unnecessary item information is not received as the fire-related information, the process of step S39 is omitted.

  On the other hand, if no fire has occurred on the floor where the mobile terminal 20 is located (step S36; No), another floor fire display is required on the floor diagram where the current position of the mobile terminal 20 is plotted. The installation positions of the items are plotted (step S40). Next, from the floor diagram in which the current position of the mobile terminal 20 and the installation positions of the items required to be displayed at another floor are plotted, the items not required to be displayed at another floor are deleted (step S41). That is, in steps S40 to S41, using the floor plan information generated in step S33, a symbol or the like indicating another floor fire display required item is added, and a symbol or the like indicating another floor fire display unnecessary item is deleted. Floor map information for displaying the displayed floor plan image is generated.

Then, the floor map information generated in steps S40 to S41 is transmitted to the mobile terminal 20 via the communication network N and the mobile phone base station 30 (step S41). Thereby, for example, a floor plan image as shown in FIG. 3B is displayed on the screen of the mobile terminal 20.
