Description

The present invention relates to a location information system that can notify the location of a mobile terminal in a facility such as a building, and more particularly to a location information system that can visually report information on the occurrence of a fire together with the location of the mobile terminal when a fire is detected. .

Conventionally, transmitters for position information systems such as beacons that use fire detectors to wirelessly transmit device-specific identification information as position detection information are known (for example, see Patent Document 1).
In a location information system equipped with a transmitter as described above, map information that associates each identification information of a plurality of transmitters arranged at different positions with each installation location is prepared in advance and given to a mobile terminal. . When a user of a mobile terminal moves with the mobile terminal in his or her possession, the mobile terminal receives identification information from transmitters placed at various locations within the building. Based on the information, the location within the building can be displayed on the display section of the mobile terminal along with a map, and the owner of the mobile terminal can grasp his or her location.

JP2018-072965A

However, with conventional location information systems that use transmitters such as beacons, it is possible to determine the location of a mobile device within a building. Although the occurrence of the fire was recognized, the location of the fire could not be ascertained. If the location of a fire can be ascertained, appropriate evacuation and fire extinguishing operations can be carried out, and the advantage is that fire initial response operations can be carried out reliably.

On the other hand, a building is usually equipped with a fire detection system or a disaster prevention monitoring system that detects the occurrence of a fire or the like and issues an alarm. Therefore, when the fire detection system or disaster prevention monitoring system detects the occurrence of a fire, it transmits the fire occurrence information and the occurrence location information to the location information system, and the location information system sends the fire information to the mobile terminal located in the building. It is conceivable to transmit the information to display the occurrence of a fire on the display unit, or to display the location of the fire on a map.

However, since map information is not very urgent information, map information is generally transmitted from a location information system to a mobile terminal every several minutes to several tens of seconds. On the other hand, fire information is highly urgent information. Therefore, if fire information is transmitted at the time of regular map information transmission, there is a risk that notification of fire occurrence to mobile phone owners will be delayed. Furthermore, in order to provide a location information system with an emergency information transmission function, there is a problem in that the programs of servers and the like that make up the location information system must be significantly modified.
The present invention was made against the above background, and its purpose is to quickly display the occurrence of a fire on the display section of a mobile terminal without significantly modifying the program of the server or the like. The objective is to provide a possible location information system.

Hereinafter, embodiments 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 showing an example of a schematic configuration of a location information system according to this embodiment.
As shown in FIG. 1, the location information system of this embodiment is a mobile terminal capable of receiving signals (radio waves) from beacons (transmitters) 10 placed at multiple locations within a predetermined area inside a building. 20, a location information server 40 that performs 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 location information server 40 that is arranged at a plurality of locations within a predetermined area inside the building. a fire receiver 60 capable of receiving a fire detection signal from a fire detector 50 located in the building; and a disaster prevention management server 80 that performs data communication with the fire receiver 60 via a gateway (repeater) 70 and a communication network N. , a push notification system 90 that can directly send messages to the mobile terminal 20 via the communication network N, and the like.
Note that the communication network N may be a network using secure lines, or may be a network using partially independent lines.

The push notification system 90 includes a server (push notification execution server) 91 that has an API (application programming interface) function, a function to send push notifications, a management function to manage messages to be sent and sending time, etc., and a server that stores programs and the like. It can be configured by a storage device 92 or the like. Furthermore, an existing system can be used as the push notification system 90. In that case, the push notification system 90 may send information such as earthquake early warnings in response to requests from other systems, in addition to notifications of fire outbreaks to be described later, even when the mobile terminal has not started the app. can also be notified.
Note that the location information server 40 and the push notification execution server 91 may be configured as one support server. Similarly, the disaster prevention management server 80 may be configured as a common support server with the location information server 40 and the push notification execution server 91.

Communication methods of the beacon 10 that transmits wireless signals (specific information such as device ID and equipment information) to the mobile terminal 20 include, for example, Bluetooth (registered trademark) communication, wireless LAN such as WiFi according to the IEEE 802.11 standard, and infrared communication. , visible light communication, and other known communication methods can be used. Although the interval at which the beacons 10 are arranged is not particularly limited, in the following description, it is assumed that the beacons 10 are arranged so that the communication range of each adjacent beacon 10 covers the space inside the building.

Specifically, since fire detectors 50 and sprinkler heads are originally installed at predetermined intervals in buildings, beacons 10 built into or attached to these devices, or those devices It is possible to use a beacon 10 installed in the vicinity of the vehicle.
The beacon 10 includes a transmitter that periodically transmits information regarding the power source (built-in battery information or external power source information) and self-identification information to the surrounding area on a wireless signal. The signal (beacon signal) wirelessly transmitted by the beacon 10 only needs to include at least the identification information of the beacon 10 (device ID of the transmitter), and further include information regarding the area where it is installed. Also good. Therefore, information regarding the power source does not need to be included.

The mobile terminal 20 is a device such as a smartphone that has a receiving function for receiving a signal from the beacon 10 and a wireless communication function. The internal memory of the mobile terminal 20 receives beacon signals that are periodically transmitted wirelessly from the beacon 10, extracts identification information (device ID), etc. included in the beacon signal, and stores the received radio waves of the beacon signal. A process of detecting the strength and transmitting beacon information including identification information, etc. and received radio wave strength and identification information (terminal ID) unique to the mobile terminal to the location information server 40, and a floor map transmitted from the location information server 40. An application program (location information display application) that executes a process of displaying a floor plan image based on information on a screen is stored. When the mobile terminal 20 receives beacon signals transmitted from a plurality of beacons 10 (beacons 10 whose communication ranges overlap each other), the mobile terminal 20 transmits respective beacon information to the position information server 40.

For example, when the fire detector 50 detects the occurrence of an abnormal phenomenon such as heat, smoke, flame, or harmful gas, it transmits a fire detection signal to the fire receiver 60 via the detector line 51. The fire detector 50 may be a type of sensor 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 the fire receiver 60 receives a fire detection signal from the fire detector 50, the fire receiver 60 displays a fire alarm on the display, and also controls the ringing of the district bell, smoke prevention interlocking, and the like. Furthermore, the fire receiver 60 transmits fire information including fire occurrence location information, fire occurrence time information, etc. to the disaster prevention management server 80 via the gateway 70 and the communication network N.
Note that, if the installation address of the fire detector 50 is added to the fire detection signal, the fire receiver 60 identifies the place where the fire has occurred 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 is specified based on the sensor line 51 (warning area) that transmitted the fire detection signal.

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

When the location information server 40 receives the device ID and terminal ID of the beacon 10 from the mobile terminal 20, it calculates the current location of the mobile terminal 20 based on the received device ID of the 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 (icon) indicating the current position of the mobile terminal 20 is added to the read floor map to generate floor display information, A process of transmitting the generated floor display information to the mobile terminal 20 that transmitted the terminal ID is executed. Thereby, a floor map image indicating the current position of the mobile terminal 20 is displayed on the mobile terminal 20.

Next, an outline of the communication sequence between the location information server 40 and the mobile terminal 20 and between each server 40, 80 and the push notification system 90 in the location information system of the above embodiment will be explained using FIG. .
In normal situations without a fire, when the mobile terminal 20 starts a general-purpose map application within a predetermined area, the mobile terminal 20 receives a device ID from a nearby beacon 10, and inputs the received device ID and its own terminal ID. Transmit to the location information server 40 (#1).

Then, the location information server 40 grasps the location of the mobile terminal 20 that sent the ID from the received beacon device ID, reads map information from the database 41, and creates a map with an icon or the like added to the location of the terminal on the map. Create data and send it to the mobile terminal 20 (#2). The mobile terminal 20 periodically (for example, every minute) transmits the beacon device ID to the location information server 40, and the location information server 40 periodically transmits the map data in response. If a plurality of mobile terminals 20 that have started a general-purpose map application exist within a predetermined area, the location information server 40 transmits the map data to all mobile terminals 20 within the area. Note that the location information server 40 may be configured to periodically (for example, every minute) transmit map information to mobile terminals within a predetermined area without receiving the ID from the mobile terminal 20.

When a fire occurs and the fire receiver 60 detects it, it transmits fire information including the occurrence and location of the fire to the disaster prevention management server 80 (#3). Then, the disaster prevention management server 80 transmits information about the occurrence of the fire and the location of the fire to the location information server 40 (#4).
Then, the location information server 40 refers to the table in the database 41 to determine the attributes or type of the mobile phone holder based on the already known terminal IDs of the mobile terminals 20 in the area, and detects the occurrence of a fire. The mobile terminals to be notified are selected and a request for push notification of the occurrence of a fire to the selected mobile terminals is made to the push notification system 90 (#5).

Upon receiving the request, the push notification system 90 immediately (for example, within one second) sends a push notification to the selected mobile terminal to notify it of the occurrence of a fire (#6). Then, the mobile terminal 20 that has received the push notification makes the speaker sound and displays a message on the display unit notifying the user of the occurrence of a fire (#7). This allows the mobile phone owner to quickly learn of the occurrence of a fire.
Thereafter, at the regular transmission timing, the location information server 40 creates map data with an icon indicating the current location of the mobile terminal 20 and an icon indicating a fire at the location of the fire, and transmits it to the mobile terminal 20 ( #8). This allows the mobile phone holder to know his or her location and the location of the fire.

Note that when the location information server 40 creates map data in which an icon indicating a fire is added to the fire location, the database 41 Information on equipment to be displayed according to the attribute or type of the mobile phone holder may be read by referring to the display range specification table in the mobile terminal, and display data for the mobile terminal may be generated and transmitted.
Here, the display range specification table is information regarding whether or not items such as equipment provided on each floor of the building are to be displayed on the floor plan, and an example thereof is shown in FIG. 3.

As shown in Figure 3, in the display range specification table, users (visitors), staff, managers (responsible persons), etc. The range of facilities (such as hallways and common areas such as elevators) to be displayed on the floor plan displayed on the mobile terminals owned by mobile phone owners with different attributes, such as , is registered separately for normal times and emergencies.
Incidentally, the display range specification table shown in FIG. 3 is created based on the idea shown in Table 1 below, for example.

また、図４には、図３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４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。
したがって、本実施形態の位置情報システムによれば、携帯保有者の属性（権限、資格等）によって異なる地図情報を表示させることができる。

Further, FIG. 4 shows an example of a floor map displayed on a user's (visitor's) mobile terminal according to the display range specification table of FIG. 3 during normal times and during an emergency. In FIG. 4, (a) is an example of a floor diagram displayed during normal times, and (b) is an example of a floor diagram displayed in the event of an emergency such as a fire outbreak.
Therefore, according to the location information system of this embodiment, different map information can be displayed depending on the attributes (authority, qualifications, etc.) of the mobile phone holder.

Furthermore, when the location information server 40 of this embodiment receives fire information (information including fire occurrence location information), information on items that need to be displayed in the event of a fire, and information on items that do not need to be displayed in the event of a fire from the disaster prevention management server 80, , is configured to be able to execute a process of generating floor plan display information that reflects these information and transmitting it to the mobile terminal 20 via the communication network N and the mobile phone base station 30. As a result, the mobile terminal 20 displays a mark (icon) indicating the current location of the terminal, as well as a floor map that reflects the fire information, the information on items that need to be displayed in the event of a fire, and the information on items that do not need to be displayed in the event of a fire.
Therefore, according to the position information system of this embodiment, map information that describes different items in normal times and in times of emergency can be displayed on the display unit of the mobile terminal.

As shown in FIG. 1, the disaster prevention management server 80 includes a database 81 that stores equipment/equipment information of each building managed by the disaster prevention management server 80. Here, the building equipment/equipment information refers to the display/hide table regarding whether or not to display items such as equipment/equipment installed on each floor of the building on the floor map, and the information on each floor of the building. This information includes installation position information of items such as equipment and equipment installed on the floor. Note that the display/non-display table and the installation position information of equipment and equipment may be stored in a database 41 connected to the position information server 40.

For example, as shown in Figure 5, the display/hide table includes building equipment ( partitions, room names, entrances and exits, doors ) , various inter-floor movement equipment (e.g. stairs, elevators, escalators), and various disaster prevention-related equipment ( For example, emergency exits) , fire alarm equipment (communicators such as district bells, etc.), fire extinguishing equipment (fire hydrants, etc.), fire extinguishing equipment (fire extinguishers, etc.), emergency telephones, smoke prevention equipment (fire doors, fire shutters, Information (flag) on whether to display items such as smoke vents, etc. during normal times (not during a fire), information on whether to display them when a fire is occurring on the same floor, and information on whether to display items on another floor. Information such as whether to display when a fire is occurring is registered. The transmitter shown in FIG. 5 is a fire transmitter that includes a built-in push button switch that generates a signal to notify the fire receiver of the occurrence of a fire.

When the disaster prevention management server 80 receives fire information from the fire detector 50, it can execute a process of transmitting the fire information to the location information server 40 via the communication network N.
Further, the disaster prevention management server 80 identifies the building where the fire has occurred based on the fire information, and acquires equipment/equipment information of the identified building from the database 81. Then, based on the acquired equipment/equipment information, there is information on items that are not required to be displayed in the event of a fire, which specifies items that are displayed during normal times but not displayed in the event of a fire, and item information that is required to be displayed in the event of a fire, which specifies items that are not displayed during normal times but are to be displayed in the event of a fire. It is possible to perform a process of generating item information and transmitting the generated information to the position information server 40 via the communication network N.

Figure 6(a) shows an example of a floor plan displayed on a user's (visitor's) mobile terminal in normal times when the building is a commercial facility, and Figure 6(b) shows an example of a floor plan displayed on a user's (visitor) mobile terminal when the building is a commercial facility. ) is shown as an example of a floor map displayed on a user's (visitor's) mobile terminal. As can be seen by comparing Figures 6(a) and (b), in the event of an emergency, in addition to your location, the location of the emergency stairs and the location of the fire, which are unnecessary information during normal times, are displayed. Therefore, appropriate evacuation actions can be taken promptly.

Further, FIG. 7 shows an example of a floor diagram that is displayed on a portable terminal of a manager or self-defense firefighter in the event of an emergency (fire outbreak) when the building is a commercial facility. As can be seen from Figure 7, in the event of an emergency, the administrator's or self-defense firefighter's mobile terminal displays their own location, the grounding location of fire hydrants and emergency telephones, and the location of the fire outbreak, so they can quickly be able to carry out fire extinguishing activities and report fires to relevant departments such as the fire department.

Furthermore, if you touch a part of the screen of the mobile terminal 20 on which the floor map is displayed, where a symbol, etc. (for example, a highlighted symbol, etc.) indicating operable equipment/equipment is displayed, the corresponding operation becomes possible. Information regarding the equipment/equipment (for example, equipment information and operation method of operable equipment/equipment) may be displayed. As a result, even mobile phone owners who are not familiar with how to use operable equipment and equipment can perform appropriate fire extinguishing operations, thereby making it possible to prevent the spread of fire.

Next, processing procedures by the mobile terminal 20, disaster prevention management server 80, and location information server 40 that constitute the location information system of this embodiment will be explained using flowcharts shown in FIGS. 8 and 9.
When the location information display application is started, the mobile terminal 20 first determines whether a beacon signal transmitted from the beacon 10 has been received, as shown in FIG. 8(a), for example (step S11). When 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 field strength of the beacon signal is sent to the mobile phone. It is transmitted to the location information server 40 via the base station 30 and communication network N (step S12).

Next, it is determined whether floor map information transmitted from the location information server 40 has been received (step S13). If 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). As a result, in the first step S14 after starting the location information display application, the latest floor map image will be displayed on the screen of the mobile terminal 20, and in the second and subsequent steps S14 after starting the location information display application, The floor map image currently displayed on the screen is updated to the latest floor map image.

For example, as shown in FIG. 8(b), the disaster prevention management server 80 first determines whether fire information (information including fire occurrence location information, fire occurrence time information, etc.) transmitted from the fire receiver 60 has been received. (Step S21). When fire information is received (step S21; Yes), the fire information is transmitted to the location 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, equipment/equipment information of the identified building is acquired from the database 81, and item information required to be displayed in the event of a fire is obtained 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, information on items that do not need to be displayed in the event of a fire is generated based on the acquired equipment/equipment information, and the generated information on items that do not need to be displayed in the event of a fire is transmitted to the position information server 40 via the communication network N (step S24).
Note that if the building in which the fire is occurring does not have an item that needs to be displayed in the event of a fire on the same floor and an item that needs to be displayed in the event of a fire on another floor, the process of step S23 is omitted. Furthermore, if the building where the fire is occurring does not have an item that does not need to be displayed in the event of a fire on the same floor or an item that does not need to be displayed in the event of a fire on another floor, the process of step S24 is omitted.

FIG. 9 shows an example of a processing procedure by the location information server 40.
As shown in FIG. 9, the location information server 40 first determines whether fire information notifying the occurrence of a fire has been received from the disaster prevention management server 80 (step S27). If it is determined that fire information has been received (Yes), a fire occurrence flag is set (step S28), and a table in the database 41 is referred to to select a mobile terminal that should be notified of the occurrence of a fire (step S28). S29). Next, the push notification system 90 is requested to issue a push notification of the occurrence of a fire to the mobile terminals selected in step S29 (step S30). If it is determined in step S27 that fire information has not been received (No), the process moves to step S31.

In step S31, the location information server 40 determines whether beacon information transmitted from the mobile terminal 20 has been received. If 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, terminal ID, and information stored in the database 41 (step S32). ), the database 41 is referred to using the terminal ID to determine the attributes of the owner of the mobile terminal (step S33). Next, the display range according to the attribute is determined with reference to the table in FIG. 2 (step S34), the floor map of the floor where the mobile terminal 20 is located is extracted from the database 41, and the extracted floor map is A mark indicating the current position of the mobile terminal 20 is plotted, and floor map information displaying the equipment within the display range is generated (step S35).

Next, the location information server 40 determines whether a fire outbreak flag is set (step S36). If it is determined that the fire occurrence flag is not set (step S36; No), the process moves to step S44, and the floor plan information generated in step S33 is transmitted via the communication network N and the mobile phone base station 30. The information is transmitted to the mobile terminal 20. As a result, a floor map image as shown in FIG. 6(a), for example, is displayed on the screen of the mobile terminal 20.

On the other hand, if it is determined that the occurrence flag is set (step S36; Yes), the process proceeds to step S37, and fire-related information (fire information, item information required to be displayed in the event of a fire) regarding the building where the mobile terminal 20 is located. , item information that is not required to be displayed in the event of a fire) is received. If the fire-related information regarding the building where the mobile terminal 20 is located is received (step S37; Yes), the location of the fire is specified based on the fire-related information, and the mobile terminal 20 is located at the location where the fire occurred. It is determined whether a fire is occurring on the floor where the fire is occurring (step S38).

If a fire has occurred on the floor where the mobile terminal 20 is located (step S38; Yes), the location of the fire is plotted on the floor map on which the current position of the mobile terminal 20 is plotted. (Step S39), and the installation positions of items that need to be displayed in the event of a fire on the same floor are plotted (Step S40). Next, items that do not need to be displayed in the event of a fire on the same floor are deleted from the floor map in which the current position of the mobile terminal 20, the location of the fire, and the installation positions of the items that need to be displayed in the event of a fire on the same floor are plotted (step S41). That is, in steps S39 to S41, using the floor map information generated in step S35, symbols etc. indicating the location of the fire and symbols etc. indicating the items required to be displayed in the event of a fire on the same floor are added, and Floor map information is generated for displaying a floor map image in which symbols and the like indicating items that do not need to be displayed are deleted.

Then, the floor plan information generated in steps S39 to S41 is transmitted to the mobile terminal 20 via the communication network N and mobile phone base station 30 (step S44). As a result, a floor map image (10th floor) as shown in FIG. 6(b), for example, is displayed on the screen of the mobile terminal 20.
Note that if the fire-related information does not include the item information that needs to be displayed in the event of a fire, the process of step S40 is omitted. Further, if the fire-related information does not include item information that is not required to be displayed in the event of a fire, the process of step S41 is omitted.

On the other hand, if a fire does not occur on the floor where the mobile terminal 20 is located (step S38; No), the current position of the mobile terminal 20 must be displayed on the floor map on which there is a fire on another floor. The installation positions of the items are plotted (step S42). Subsequently, items that do not need to be displayed in the event of a fire on another floor are deleted from the floor map in which the current position of the mobile terminal 20 and the installation position of the item that needs to be displayed in the event of a fire on another floor are plotted (step S43). That is, in steps S42 and S43, using the floor map information generated in step S35, symbols etc. indicating items that need to be displayed in the event of a fire on another floor are added, and symbols etc. indicating items that do not need to be displayed in the event of a fire on another floor are deleted. Floor plan information for displaying the created floor plan image is generated. Note that symbols indicating files that are not required to be displayed in the event of a fire on another floor may be grayed out on the screen without being deleted from the floor map image.

Then, the floor plan information generated in steps S42 and S43 is transmitted to the mobile terminal 20 via the communication network N and mobile phone base station 30 (step S44). As a result, a floor map image of another floor (for example, the 9th floor) will be displayed on the screen of the mobile terminal 20.
Note that if the fire-related information does not include the item information that needs to be displayed in the event of a fire, the process of step S40 is omitted. Further, if the fire-related information does not include item information that is not required to be displayed in the event of a fire, the process of step S41 is omitted.

As described above, according to the location information system of this embodiment, even if map information is periodically transmitted from the location information server 40 to the mobile terminal 20 at predetermined time intervals, when a fire occurs, the push notification system 90, a push notification is immediately sent to the mobile terminal to inform the mobile terminal of the occurrence of a fire, so the owner of the mobile terminal can immediately know of the occurrence of a fire. Moreover, the existing push notification system can be used as a system for sending push notifications to mobile terminals to inform mobile terminals of the occurrence of a fire, and by simply adding information on the occurrence of a fire to map information, servers, etc. The occurrence of a fire can be promptly displayed on the display of a mobile terminal without significantly modifying the program or adding a new system.

In addition, according to the location information system of this embodiment, the location of the mobile terminal within the range of movement permitted during normal times and in the event of a fire can be determined according to the attributes of the mobile phone holder and equipment/equipment information. can notify the location of the fire, the location of the mobile terminal, the location of equipment related to fire extinguishing operations, the location of emergency exits, etc., so it is possible to quickly take initial actions in the event of an emergency while ensuring security. can do.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the gist thereof. For example, in the above embodiment, it was explained that a signal from a beacon is received by a mobile terminal and the received information is transmitted to a location information server by wireless communication. However, if the monitoring target area is a space such as an office, Connect a device that can receive signals from beacons to the computer installed on the desk inside the office, and have the computer send the information received by the device to the location information server via the LAN (Local Area Network). It's okay.

In addition, in the above embodiment, it was explained that the beacon only has the function of transmitting information, but it also has the function of receiving wireless signals from mobile terminals and other transmitters (wireless tags, terminals, etc.). It may also have a function of transmitting information to a server.
Furthermore, in the above embodiments, a system that uses positioning using a beacon is exemplified as a positioning information system, but the positioning information system is not limited to this, and the positioning information system may also use positioning using other methods such as IMES (Indoor MEssaging System). It may be the system used. That is, the transmitter is not limited to a beacon, but may be an IMES transmitter or the like.

Furthermore, in the above embodiments, the location specifying process of the location information system is performed by the server, but part or all of the process may be performed by the mobile terminal.
Furthermore, the position specifying process of the position information system may be one-point positioning of a beacon or multi-point positioning (processing of specifying a position using signals from a plurality of beacons).
Further, in the above embodiment, a case where a fire is detected by a fire monitoring device is described as an example of an emergency, but the present invention may also be applied to a case where another emergency such as an earthquake or a flood occurs.
