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 the position information system according to the present embodiment.
As shown in FIG. 1, the position information system according to the present embodiment is a portable terminal capable of receiving signals (radio waves) from beacons (transmitters) 10 arranged at a plurality of locations in a predetermined area inside a building. 20, a location information server 40 that performs data communication with the mobile terminal 20 via the mobile phone base station 30 and the communication network N such as the Internet, and a plurality of locations located in a predetermined area inside the building. Fire information for performing data communication between the fire receiver 60 capable of receiving a 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 server 80 and the like. The position information server 40 and the fire information server 80 may be configured as one support server.

  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, a Bluetooth (registered trademark) communication, a wireless LAN such as WiFi in accordance with the IEEE 802.11 standard, and the like. Known communication methods such as infrared communication and visible light communication can be used. The interval at which the beacons 10 are arranged is not particularly limited. However, in the following description, it is assumed that the communication range of each adjacent beacon 10 is arranged so as to cover the space in the building.

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 (device ID of the transmitter), and further includes information on the installed area. Is also good.

  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 internal memory of the mobile terminal 20 periodically receives a beacon signal wirelessly transmitted from the beacon 10 to extract identification information (device ID) and the like included in the beacon signal, and receives a radio wave of the beacon signal. Processing for detecting the intensity and transmitting beacon information including identification information and the like and received radio wave intensity to the location information server 40 via the mobile phone base station 30 and the communication network N; An application program (position information display application) for executing a process of displaying a floor plan image on the screen based on the floor plan information transmitted from the position information server 40 via the server 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, or 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 the fire detection signal, or may be a type of sensor that does not add its own installation address to the fire detection signal.

When receiving a 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.
When the installation address of the fire detector 50 is added to the fire detection signal, the fire receiver 60 specifies the location where the fire has occurred based on the installation address. On the other hand, when the installation address of the fire detector 50 is not added to the fire detection signal, the location where the fire has occurred is specified based on the detector line 51 (alert area) that transmitted the fire detection signal.

  The location information server 40 includes map information (floor diagram) of each floor of the building managed by the location information server 40, identification information (terminal ID) unique to the mobile terminal, authority of the user (mobile terminal holder), A database 41 is provided for storing information on attributes such as qualifications (user attribute information) or a display range specification table associated with user type information. Note that the map information (floor diagram information) of each floor includes the device ID and the installation position information of the beacon 10 installed on each floor.

  When receiving the device ID of the beacon 10 from the mobile terminal 20, the position information server 40 calculates the current position of the mobile terminal 20 based on the device ID of the received beacon and the information stored in the database 41. Then, the map information of the floor where the mobile terminal 20 is located is read from the database 41, and a mark indicating the current position of the mobile terminal 20 is plotted on the read floor diagram to generate floor display information. A process of transmitting the display information to the mobile terminal 20 via the communication network N and the mobile phone base station 30 is executed. Thereby, the floor map image indicating the current position of the mobile terminal 20 is displayed on the mobile terminal 20.

Further, the position information server 40 determines the attribute or type of the user based on the device ID and the terminal ID of the transmitter transmitted from the mobile terminal 20, and refers to the display range specification table to determine the attribute of the user. Alternatively, information of the equipment to be displayed is read according to the type, and display data of the mobile terminal is generated and transmitted.
Here, the display range designation table is information on whether or not items such as facilities provided on each floor of the building are displayed on the floor plan, and an example thereof is shown in FIG.

As shown in FIG. 2, in the display range specification table, for example, for each facility such as a hotel, a residential area, an office, a hospital, and a commercial facility (store), a user (a visitor), a staff member, and a manager (a responsible person) are provided. The range of equipment (common parts such as passages and elevators) displayed on a floor diagram displayed on a portable terminal owned by a user having different attributes is registered separately for normal times and emergency situations.
In addition, apart from the display range at the time of an emergency shown in the display range designation table of FIG. 2, for example, for a mobile terminal owned by a self-defense firefighter, information of a schematic layout is added and transmitted. You may make it do.

また、図３には、図２の表示範囲指定テーブルに従って利用者（訪問者）の携帯端末に表示される平時と有事の際のフロア図の一例が示されている。図３のうち、（ａ）は平時に表示されるフロア図、（ｂ）は火災発生等の有事の際に表示されるフロア図の例である。 Incidentally, the display range designation table shown in FIG. 2 is created based on the idea shown in Table 1 below, for example.

FIG. 3 shows an example of a floor diagram in a normal time and an emergency displayed on a portable terminal of a user (visitor) according to the display range designation table of FIG. 3A is an example of a floor diagram displayed during normal times, and FIG. 3B is an example of a floor diagram displayed in the event of an emergency such as a fire.

  Further, when the location information server 40 detects that the user (visitor) has entered an area that is not permitted during normal times, the location information server 40 transmits an alert notification to the user's mobile terminal to notify the user and informs the user. It may be configured to notify the manager of the area or the manager of the facility of unauthorized entry. Further, even when a function for performing such a notification is provided, an alert may not be notified in an emergency or the function may be disabled.

Even when the above-mentioned alert notification is set, the time limit and permission section are set for visitors who want to enter the room temporarily, such as visitors and workers who perform inspection and repair work on equipment. The setting may be made to allow entry to the room, and upon detecting that the time limit has been exceeded or entry into an area other than the permitted section, an alert may be sent to the portable terminal of the witness (resident or manager).
Therefore, according to the position information system of the present embodiment, different map information can be displayed depending on the attributes (authority, qualifications, etc.) of the user.

Further, when the position information server 40 of the present embodiment receives the fire information (information including the fire occurrence location information), the fire display required item information, and the fire display unnecessary item information from the fire information server 80, In addition, it is configured to be able to execute processing of generating floor view display information reflecting these pieces of information and transmitting the generated information to the mobile terminal 20 via the communication network N and the mobile phone base station 30. As a result, a floor plan reflecting the fire information, the fire display required item information, and the fire display unnecessary item information is displayed on the portable terminal 20 along with the mark indicating the current position of the terminal.
Therefore, according to the position information system of the present embodiment, it is possible to cause the display unit of the portable terminal to display map information in which different items are displayed in normal times and in emergency.

  As shown in FIG. 1, the fire information server 80 includes a database 81 that stores facility / 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 plan, This is information including installation position information of items such as equipment and devices installed on the floor. Note that the display / non-display table and the installation position information of the facility / equipment may be stored in the database 41 connected to the position information server 40.

  In the display / non-display table, for example, as shown in FIG. 4, partitions, room names, doorways, doors, facilities for moving between various floors (for example, stairs, elevators, escalators), and various disaster prevention-related facilities and equipment (for example, Items such as emergency exits, fire alarms (e.g., transmitters for district bells, etc.), fire extinguisher (fire extinguishers, fire hydrants, etc.), emergency telephones, smoke evacuators (fire doors, fire shutters, smoke vents, etc.) Information (flag) as to whether or not to display during normal times, not when a fire occurs, information as to 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 Information on whether or not it is registered is registered. The transmitter shown in FIG. 4 is a fire transmitter having a built-in pushbutton switch for generating a signal for notifying a fire receiver of the occurrence of a fire.

Upon 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, it is necessary to display item information that is displayed during normal operation but not displayed during a fire. A process of generating item information and transmitting the generated information to the position information server 40 via the communication network N can be executed.

  FIG. 5A shows an example of a floor diagram displayed on a mobile terminal of a user (visitor) in a normal time when the building is a commercial facility, and FIG. 5B shows an emergency (fire occurrence). 2) shows an example of a floor diagram displayed on the portable terminal of the user (visitor). As can be seen by comparing FIGS. 5A and 5B, in an emergency, in addition to the position where the user is, the position of the emergency stairs and the fire occurrence position, which are unnecessary information in normal times, are displayed. Therefore, appropriate evacuation behavior can be taken promptly.

  FIG. 6 shows an example of a floor diagram displayed on a portable terminal of a manager or a self-defense firefighter in the event of an emergency (fire) when the building is a commercial facility. As can be seen from FIG. 6, in the event of an emergency, the location of the fire hydrant or emergency telephone and the location of the fire are displayed on the mobile terminal of the manager or the self-defense firefighter, in addition to the location of the user. Fire extinguishing activities and fire reports to fire departments and other related departments can be carried out.

  Further, when the user touches a portion on the screen of the mobile terminal 20 on which the floor diagram is displayed, the symbol or the like indicating the operable facility / equipment (for example, a highlighted symbol) is displayed. Information on equipment / equipment (for example, equipment information or operation method of operable equipment / equipment) may be displayed. As a result, even a user 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 of the present embodiment will be described with reference to flowcharts shown in FIGS.
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. 7A (step S11). If a beacon signal is received (step S11; Yes), the beacon information including the identification information (device ID) of the beacon 10 included in the beacon signal and the received radio wave intensity of the beacon signal is transmitted to the mobile phone. It transmits to the location information server 40 via the base station 30 and the communication network N (step S12).

  Next, it is determined whether the floor map 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 displayed on the screen is updated to the latest floor plan image.

  For example, as shown in FIG. 7B, 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 identified based on the fire information, the equipment / equipment information of the identified building is acquired from the database 81, and the item information required for fire display is acquired based on the acquired equipment / equipment information. Is generated, and the generated fire display required item information is transmitted to the position information server 40 via the communication network N (step S23). Next, based on the acquired facility / equipment information, the display-unnecessary item information at the time of fire is generated, and the generated fire-display-unnecessary item information is transmitted 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 display required item and another floor display required item, the process of step S23 is omitted. If the building where the fire has occurred does not have the display unnecessary item on the floor and the display unnecessary item on another floor, the process of step S24 is omitted.

FIG. 8 shows an example of a processing procedure performed by the position information server 40.
As shown in FIG. 8, the position information server 40 first determines whether beacon information transmitted from the mobile terminal 20 has been received (step S31). When it is determined that the beacon information has been received (Yes), the current position of the mobile terminal 20 is calculated based on the received beacon information and the terminal ID and the information stored in the database 41 (step S32). ), The attribute of the user of the portable terminal is determined by referring to the database 41 using the terminal ID (step S33). Subsequently, the display range according to the attribute is determined with reference to the table of FIG. 2 (step S34), and the floor diagram of the floor where the portable terminal 20 is located is extracted from the database 41, and the extracted floor diagram is displayed. A mark indicating the current position of the portable terminal 20 is plotted, and floor map information indicating facilities in the display range is generated (step S35).

Next, it is determined whether a fire has occurred in the building where the mobile terminal 20 is located (step S36). Here, the position information server 40 determines whether a fire has occurred in the building where the portable terminal 20 is located, for example, by inquiring 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 mobile terminal 20 is located is received, a fire occurs in the building where the mobile terminal 20 is located. Can be determined.
If it is determined that no fire has occurred in the building where the portable terminal 20 is located (step S36; No), the floor map information generated in step S33 is transmitted to the communication network N and the cellular phone base station 30. Is transmitted to the portable terminal 20 via the terminal (step S42). Thereby, for example, a floor plan image as shown in FIG. 5A 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 S36; 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 in case of fire) has been received (step S37). Then, when the fire-related information regarding the building where the portable terminal 20 is located is received (step S37; 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 has occurred (step S38).

  If a fire has occurred on the floor where the portable terminal 20 is located (Step S38; Yes), the fire occurrence position is plotted on the floor diagram where the current position of the portable terminal 20 is plotted. (Step S39), the installation positions of the items required to be displayed at the time of the floor fire are plotted (Step S40). Next, the floor unnecessary display item is deleted 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 required display item are plotted (step S41). That is, in steps S39 to S41, using the floor diagram information generated in step S35, 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 map information generated in steps S39 to S41 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 (the tenth floor) as shown in FIG. 5B 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 S40 is omitted. In addition, when the fire-unnecessary display unnecessary item information is not received as the fire-related information, the process of step S41 is omitted.

  On the other hand, if a fire has not occurred on the floor where the mobile terminal 20 is located (step S38; No), another floor fire display is required on the floor diagram in which the current position of the mobile terminal 20 is plotted. The installation positions of the items are plotted (step S42). 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, items unnecessary to be displayed at another floor are deleted (step S43). That is, in steps S42 to S43, using the floor plan information generated in step S35, 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 S42 to S43 is transmitted to the mobile terminal 20 via the communication network N and the mobile phone base station 30 (step S41). As a result, a floor plan image of another floor (for example, the ninth floor) 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 S40 is omitted. In addition, when the fire-unnecessary display unnecessary item information is not received as the fire-related information, the process of step S41 is omitted.

As described above, in the position information system of the present embodiment, the servers (the position information server 40 and the fire information server 80) transmit the fire information (the information including the fire occurrence location information) transmitted by the receiver (the fire receiver 60). ), Map information (floor diagram display information) for displaying the map image (floor diagram image) indicating the current position of the portable terminal 20 and the fire occurrence position on the portable terminal 20 is displayed on the portable terminal 20.
