Description

The present invention relates to a system for identifying people during evacuation that can identify the number of people who have evacuated from inside a building to outdoors in the event of a disaster such as a fire or earthquake.

In recent years, disaster prevention support systems are being put into practical use that support firefighting activities by transmitting information such as the location of a fire and instructions regarding firefighting activities based on information from a fire receiver to terminals carried by members of the private fire brigade.
An invention relating to such a disaster prevention support system is known that includes a support device and a terminal, in which the support device transmits location inquiry information to the terminal when it receives abnormality information, the terminal measures its own location using a satellite positioning system when it receives the location inquiry information, the support device determines whether the terminal is located within a facility or not, and stores the determination result information in a storage unit in association with the ID of the firefighter carrying the terminal. If the stored information indicates that the terminal is located within the facility, the support device transmits support information relating to the abnormality to the terminal, and the terminal displays the support information on a display unit when it receives the support information (for example, Patent Document 1).

On the other hand, when a disaster such as a fire or earthquake occurs, it is sometimes necessary to check whether there are any people in a building who were unable to escape in time. One invention related to such a user location management system is to install a beacon device in each section of a building, such as a room, and have it repeatedly transmit a beacon signal including a section ID. When a terminal such as a smartphone carried by a user using the building receives the beacon signal, it transmits a location report including the section ID extracted from the beacon signal and the user's own terminal ID to a server. The server then collects and manages user location information indicating the section in which the terminal is located based on the terminal ID and section ID included in the location report received from the user's terminal, and when a fire detection signal is received from a fire receiver, it detects a user terminal located in the section where the fire occurred from the user location information and outputs this as information on users who were unable to escape in time (see Patent Document 2).

JP 2018-147439 A JP 2019-032867 A

However, the disaster prevention support system of Patent Document 1 can support the activities of the self-defense fire brigade, but cannot obtain information about users who are unable to escape. On the other hand, the user location management system of Patent Document 2 can obtain information about users who are unable to escape, but cannot obtain information about users who have evacuated from the building where the system is located to the outdoors. In addition, if the user is outdoors, it is possible to grasp the location using the GPS function of the terminal carried by the user, but the user may evacuate to an evacuation site near the building, and if the accuracy of the GPS is low, it is not suitable for evacuation confirmation. In addition, there is a problem that GPS information cannot be used for evacuation confirmation unless the evacuated user sets the GPS function of the terminal carried to an enabled state.
Furthermore, when evacuating from a disaster, etc., a roll call will be taken after people have evacuated to a pre-designated temporary evacuation site to check whether anyone was unable to escape. However, if there are a large number of people or the temporary evacuation site is small, it will take time to take a roll call, and even when every second counts, there is a risk that the identification of people who were unable to escape will be delayed.

This invention has been made with attention to the above-mentioned problems in mind, and its purpose is to provide an evacuation personnel identification system that utilizes an indoor location information system to identify the number of people who have evacuated from inside a building to the outdoors in the event of a disaster such as a fire or earthquake.
Another object of the present invention is to provide a system for determining the number of people evacuated during an evacuation, which can determine the number of people evacuated in the event of a disaster without having to install a device with a specified function in advance at any evacuation site set outdoors, and which can easily respond if the evacuation site changes.

Here, the "predetermined device" includes mobile terminals such as smartphones, tablet terminals, and PDAs (personal digital assistants), as well as data processing devices such as PCs (personal computers).
According to the system for grasping the number of people during evacuation having the above-mentioned configuration, the server identifies the location of the mobile terminal based on the transmitter information from the mobile terminal and transmits map information indicating the location to the mobile terminal, so that the owner of the mobile terminal can grasp the location of himself or herself and others by displaying the map information on the display unit. In addition, by receiving the information on the mobile terminal located at the temporary evacuation site transmitted by the server and displaying it on the display unit of the mobile terminal or PC (personal computer), it is possible to grasp the number of people who have evacuated from inside the building to the outdoors in the event of a disaster such as a fire or earthquake. The display function may be a display unit integrated with a specified device, or a liquid crystal or organic EL display, CRT, digital signage, projector, etc. connected to a specified device.
Furthermore, since it is equipped with a portable transmitter, when a disaster occurs, the transmitter can be transported to any temporary evacuation site set up outdoors and begin transmitting radio waves (beacon signals) that serve as a marker. These radio waves can then be received by a mobile device located at the temporary evacuation site, making it possible to keep track of the number of people who have evacuated when a disaster occurs, and also easily responding if the evacuation site changes.

Here, preferably, the server
The monitoring device is capable of receiving abnormality information based on a detection signal from a sensor installed in the monitoring area,
When the anomaly information is received, the location where the anomaly has occurred is identified, and information regarding the location where the anomaly has occurred is added to the map information, which can then be transmitted to the mobile terminal.
According to this configuration, when an abnormality occurs in the monitored area and is detected by the sensor, the abnormality information is transmitted to the server, and information regarding the location of the abnormality is added to the map information from the server and transmitted to the mobile device. Therefore, the location of the abnormality can be displayed on the map displayed on the display unit, and the owner of the mobile device can determine the evacuation direction.
The detector may be not only a sensor for detecting a disaster such as a fire, earthquake, or tsunami, but also a security sensor or the like that detects an abnormality requiring evacuation and transmits information about the abnormality.

Further, preferably, the detector is a fire detector constituting a fire detection system,
The fire detection system includes a fire receiver that determines whether a fire has occurred based on a signal from the fire detector, and when the fire receiver determines that a fire has occurred, the fire receiver transmits information regarding a location of the fire as the abnormality information to the server.
The server is configured to, upon receiving information relating to the location of a fire from the fire receiver, add the information relating to the location of a fire to the map information and transmit the information to the mobile terminal.

According to this configuration, if a fire breaks out in the monitored area, information on the location of the fire is added to the map information from the server and transmitted to the mobile device, so that the location of the fire can be displayed on the map displayed on the display unit, and the mobile device owner can determine the evacuation direction. Furthermore, if the monitored area is inside a building, a fire detection system equipped with a fire detector and a fire receiver is generally installed, so that the existing fire detection system can be used to notify the mobile device owner of the location of the fire, allowing them to evacuate safely.

Here, the portable transmitter may have a function of receiving GPS radio waves and a wireless communication function in addition to the function of transmitting the beacon radio waves. This makes it possible to display a mark indicating the temporary evacuation site and information regarding the number of evacuees at an appropriate position on the map (map screen) even if the temporary evacuation site is not registered in advance or if the temporary evacuation site is changed and moved later after being set.

Also, preferably, a display device connected to the server is provided,
The server is configured to be capable of displaying, on the display device, map information indicating temporary evacuation sites and information regarding mobile terminals located at the temporary evacuation sites.
According to this configuration, by installing the display device in a disaster prevention center or the like, the fire brigade chief or the disaster prevention center can grasp the number of people who have evacuated to the temporary evacuation site, and therefore it becomes possible to carry out more appropriate activities such as searching for users who were unable to escape in time.

Hereinafter, an embodiment of the evacuation personnel identification system according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the schematic configuration of one embodiment of the evacuation personnel identification system to which the present invention is applied. In FIG. 1, the area surrounded by the solid line B indicates the interior space of the building, and the areas marked with the symbols E1 and E2 indicate the spaces of the areas partitioned by each floor or wall. As shown in FIG. 1, the evacuation personnel identification system of this embodiment includes a stationary beacon (transmitter) 10A arranged at multiple locations within a predetermined area inside the building, a portable beacon 10B, a mobile terminal 20 capable of receiving a signal (radio wave) from the beacon 10A or 10B, and 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.

In addition, the evacuation personnel identification system of this embodiment includes a fire receiver 60 capable of receiving fire detection signals from fire detectors 50 installed at multiple locations within a specified area inside the building, and a fire information server 80 that communicates data with the fire receiver 60 via a gateway (repeater) 70 and a communication network N such as the Internet.
A fire detection system is made up of the plurality of fire detectors 50 and the fire receiver 60. The fire receiver 60 judges whether a fire has occurred when it receives a fire detection signal from any of the fire detectors 50, and issues a fire alert if it judges that a fire has occurred. The location information server 40 and the fire information server 80 can communicate data with each other via the communication network N. The location information server 40 and the fire information server 80 may be configured as a single support server.

The communication method of the beacons 10 that transmit wireless signals (unique information such as device ID and facility information) to the mobile terminals 20 can be any known communication method, such as Bluetooth (registered trademark) communication, wireless LAN such as WiFi conforming to the IEEE 802.11 standard, infrared communication, visible light communication, etc. The interval at which the beacons 10A are placed is not particularly limited, but in the following description, they are placed at such a distance that the communication ranges of adjacent beacons 10A overlap each other so that the space within the building can be covered.

Specifically, since fire detectors 50 and sprinkler heads are originally installed at predetermined intervals within a building, the beacon 10A can be a beacon that is built into or attached to these devices, or a beacon that is installed in the vicinity of these devices.
The beacons 10A and 10B (hereinafter, when 10A and 10B are not distinguished from each other, they are referred to as beacons 10) as long as they have a function of transmitting signals (signal radio waves) in the same frequency band and have a transmitter that periodically transmits its own identification information (device ID) to the surroundings via a wireless signal. The signal (beacon signal) wirelessly transmitted by the beacon 10 is required to include at least the identification information (device ID) of the beacon 10, and may further include information regarding the area in which it is installed. When the beacon 10A has a power switch, the beacon 10B can be one having the same specifications as the beacon 10A.

The mobile terminal 20 is a portable information terminal such as a smartphone, tablet terminal, or PDA (personal digital assistant), and each is configured with a control unit, a memory unit, a display unit, an operation unit (for example, a touch panel provided on the display screen of the display unit), a beacon signal receiving unit that receives signals from the beacon 10, and a wireless communication unit that transmits and receives various information to and from external devices such as the location information server 40 via the communication network N.

The memory unit of the mobile terminal 20 stores an application program (location information app) that executes the following processes: receiving a beacon signal wirelessly transmitted periodically from the beacon 10, extracting identification information (device ID) and the like contained in the beacon signal, detecting the received radio wave strength of the beacon signal, and transmitting beacon information including the identification information and the received radio wave strength to the location information server 40 via the mobile phone base station 30 and the communication network N; and displaying a floor plan image including a mark indicating the mobile terminal's own location and the location of a fire on the display unit based on the map information transmitted from the location information server 40 via the communication network N and the mobile phone base station 30.
When the beacon signal receiving unit of the portable terminal 20 receives beacon signals transmitted from a plurality of beacons 10A whose communication ranges overlap each other, the control unit of the portable terminal 20 transmits each beacon information from the wireless communication unit to the location information server 40.

When the fire detector 50 detects the occurrence of an abnormal phenomenon such as heat, smoke, flames, or harmful gases, it transmits a fire detection signal (or an abnormality detection signal in the case of harmful gases) to the fire receiver 60 via the detector line 51. The fire detector 50 may be a type of detector that adds its own installation address to the fire detection signal, or a type of detector 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, it displays a fire alarm on the display unit and controls the ringing of a district bell, interlocking with smoke control devices, etc. Furthermore, the fire receiver 60 transmits fire information including information on the location and time of occurrence of a fire together with identification information (receiver ID) of the fire receiver 60 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 identifies the location of the fire 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 fire receiver 60 identifies the location of the fire based on the detector line 51 (warning area) that transmitted the fire detection signal.

The fire information server 80 includes a database 81. The database 81 stores, for example, a table that stores identification information (such as a building name and an address) of a building managed by the fire information server 80 and identification information (a receiver ID) of a fire receiver 60 installed in the building in association with each other.
When the fire information server 80 receives fire information from the fire receiver 60, it acquires, from the database 81, the building identification information (such as the building name and address) corresponding to the identification information (receiver ID) transmitted together with the fire information. Then, the fire information server 80 is capable of executing a process of transmitting the acquired building identification information together with the fire information from the fire receiver 60 to the location information server 40 via the communication network N.

The location information server 40 includes a database 41 that stores information on each building and each mobile terminal 20 managed by the location information server 40. The server (location information server) may be a server in the narrow sense, or may be a data processing device such as a PC (personal computer).
Here, the information on the building includes identification information of the building (such as the building name and address), a map of each floor of the building, identification information and installation location information of the beacons 10A installed on each floor of the building, installation location information of various disaster prevention devices and equipment installed on each floor of the building, temporary evacuation site information of the building, etc. The database 41 also stores identification information of portable beacons 10B that are not installed on each floor of the building but are registered in advance as beacons for temporary evacuation sites.

The information on the mobile terminal 20 includes identification information (terminal ID) of the mobile terminal 20, information on the user of the mobile terminal 20 (such as the user's name), etc. For example, information on the user can be input on a setting screen of a location information app displayed on the mobile terminal 20, and the input information is transmitted to the location information server 40 together with the identification information (terminal ID) of the mobile terminal 20 and stored in the database 41.

When the location information server 40 receives the beacon information transmitted by the mobile terminal 20, it calculates the location of the mobile terminal 20 based on the received beacon information and the information stored in the database 41. It is then capable of extracting a map of the floor on which the mobile terminal 20 is located from the database 41, plotting the location of the mobile terminal 20 on the extracted map to generate map information, and transmitting the generated map information to the mobile terminal 20 via the communication network N and the mobile phone base station 30. As a result, a floor plan image indicating the location of the mobile terminal 20 is displayed on the display unit of the mobile terminal 20.

In this embodiment, the portable beacon 10B is deployed in a disaster prevention center or the like in normal times, and when a disaster occurs, it is transported to a temporary evacuation site set outdoors or near a monitored area and powered on, and starts transmitting a beacon signal. The beacon signal is received by a mobile terminal 20 located nearby and transmits beacon information to the location information server 40. An image showing information about evacuees is then generated by the location information server 40 at the temporary evacuation site to which the beacon 10B has been transported, and is transmitted to the mobile terminal 20 and displayed on the display unit.

Furthermore, when the location information server 40 receives fire information from the fire information server 80, the location information server 40 can execute a process of generating map information reflecting information on the location of the fire contained in the fire information, and transmitting the generated map information to the mobile terminal 20 via the communication network N and the mobile phone base station 30. As a result, a floor plan image showing the location of the fire is displayed on the display unit of the mobile terminal 20.
1, a display device 42 such as a liquid crystal display may be provided to display a floor plan image showing the location of the fire and the location of the mobile terminal 20 on the display screen of the display device 42. The display device 42 may be a liquid crystal or organic EL display, a CRT, a digital signage, a projector, or the like.

Next, an example of the procedure for the location information display process executed by the control unit of the mobile device 20 will be described using the flowchart shown in FIG. 2. Note that this location information display process is repeatedly executed at regular intervals while the location information app is running, regardless of whether it is during a fire outbreak (when the fire detector 50 is activated) or normal times (when the fire detector 50 is not activated).

When the location information app is launched, the control unit of the mobile terminal 20 first determines whether the beacon signal receiving unit has received a beacon signal transmitted from the beacon 10 (step S11), and if the beacon signal has not been received (No), proceeds to step S13.
On the other hand, when a beacon signal is received (step S11; Yes), beacon information including the identification information (device ID) of the beacon 10 contained in the beacon signal and the received radio wave strength of the beacon signal is transmitted to the location information server 40 via the mobile phone base station 30 and the communication network N together with its own identification information (terminal ID) (step S12).

Next, it is determined whether the wireless communication unit has received map information transmitted from the position information server 40 (step S13). If map information has not been received (step S13; No), the position information display process is terminated.
On the other hand, if map information has been received (step S13; Yes), an image based on the map information (floor plan image) is displayed on the display unit (step S14), and the location information display process is terminated. As a result, in the first step S14 after the location information application is started, the latest floor plan image is displayed on the display unit, and in the second and subsequent steps S14 after the location information application is started, the floor plan image being displayed on the display unit is updated to the latest floor plan image.

In addition, the mobile terminal 20 may transmit beacon information based on the currently received beacon signal to the location information server 40, instead of transmitting beacon information to the location information server 40 each time a beacon signal is received. For example, when the identification information of the beacon 10 included in the previously received beacon signal differs from the identification information of the beacon 10 included in the currently received beacon signal, the mobile terminal 20 may transmit beacon information based on the currently received beacon signal to the location information server 40.

Next, an example of a procedure of normal processing executed by the control unit of the location information server 40 will be described with reference to the flowchart shown in FIG.
In the following description, among the mobile terminals 20 present in the building where the fire started (the building where the fire detector 50 is activated), the administrator-authorized terminal held by the administrator is referred to as a "special terminal", among the mobile terminals 20 present in the building where the fire started, the mobile terminals 20 other than the administrator-authorized terminal are referred to as "general terminals", and the holder of a general terminal is referred to as a "general terminal user". Here, the "administrator-authorized terminal" may be a mobile terminal 20 held by the head of the private fire brigade, or a fixed-type PC terminal installed in a disaster prevention center. For the purpose of description, the terminals are divided into two groups, "administrator-authorized terminals" and "general terminals", but there are not limited to these two groups. For example, there is a "private fire brigade member terminal" held by a private fire brigade member.

When the location information app is installed on an information terminal, a login ID and password are set, and the set information is sent to the location information server 40 together with the identification information (terminal ID) of the terminal and stored in the database 41. The login ID and password for administrator authority are notified to the fire brigade chief and disaster prevention center in advance, and a mobile terminal 20 for which a login ID and password for administrator authority are set during installation is registered as an administrator authority terminal. A mobile terminal 20 for which a login ID and password other than for administrator authority are set during installation is registered as a mobile terminal 20 other than an administrator authority terminal.

In the evacuation personnel identification system of this embodiment, when the fire information server 80 receives fire information (information including information on the location and time of fire occurrence, etc.) from the fire receiver 60, it obtains from the database 81 the building identification information (building name, address, etc.) corresponding to the identification information (receiver ID) of the fire receiver 60 that was sent along with the fire information, and transmits the fire information together with the obtained building identification information to the location information server 40.
When a fire occurs in any of the multiple buildings it manages (when a fire detector 50 is activated), the location information server 40 identifies the mobile terminal 20 located in the building where the fire started (the building where the fire detector 50 is activated) based on beacon information from the mobile terminal 20.

The normal processing shown in FIG. 3(a) is processing executed for mobile terminals 20 other than special terminals and general terminals. Therefore, even if a fire breaks out in any of the multiple buildings managed by the location information server 40, the normal processing is repeatedly executed at regular intervals for buildings where no fire has broken out, and if a fire breaks out in any of the multiple buildings managed by the location information server 40, the fire processing (FIG. 3(b)) described below is executed, and the normal processing (step S36) is executed in this fire processing.

In the normal processing, first, it is determined whether beacon information has been received from a mobile terminal 20 other than a special terminal or a general terminal (step S21). If beacon information has not been received (step S21; No), the normal processing is terminated.
On the other hand, if beacon information is received (step S21; Yes), the location of the mobile terminal 20 is calculated based on the received beacon information and the information stored in the database 41 (step S22), and a map of the floor (current floor) on which the mobile terminal 20 is located is extracted from the database 41 (step S23).

Next, the location of the mobile terminal 20 is plotted on the extracted map to generate map information (step S24).
Next, the map information (current floor plan information) generated in step S24 is transmitted to the mobile terminal 20 via the communication network N and the mobile phone base station 30 (step S25), and the normal processing is terminated. As a result, a floor plan image is displayed on the display unit of the mobile terminal 20, in which a map (floor plan) of the floor (current floor) on which the mobile terminal 20 is located, as shown in Fig. 4, with a mark M indicating the mobile terminal 20 written at a position corresponding to the current location of the mobile terminal 20. In Fig. 4, the circled numbers added to the marks M indicate the number of people (number of mobile terminals) at that location.

Next, an example of the procedure for the fire processing executed by the control unit of the location information server 40 will be described using the flowchart shown in FIG. 3(b). The fire processing in FIG. 3(b) is started, for example, when the fire information server 80 receives information notifying the occurrence of a fire from the fire receiver 60 and transmits the fire information to the location information server 40. Note that steps S31 to S35 in this flowchart are processes executed for special terminals and general terminals, and step S36 of the fire processing is a process executed for other mobile terminals 20 (mobile terminals 20 other than special terminals and general terminals).

In the fire processing of FIG. 3(b), first, a map of the floor on which the fire started is extracted from the database 41 (step S31), and the location of the fire is plotted on the extracted map (step S32).
Next, the locations of the special terminal and the general terminal are calculated based on the beacon information from the special terminal and the general terminal and the information stored in the database 41 (step S33), and the locations of the terminals located on the floor where the fire started are plotted on the map on which the location of the fire is plotted to generate map information (step S34). At this time, the map information may be generated in which the mobile terminal is marked so as to be distinguishable from other terminals. Also, each mark may be displayed with a number corresponding to the number of mobile terminals 20 that have transmitted the same beacon information, in order to indicate how many people are present at the location.

Next, the map information (floor plan information of the floor where the fire started) generated in step S34 is transmitted to the special terminal and the general terminal via the communication network N and the mobile phone base station 30 (step S35). As a result, the display unit of the special terminal and the general terminal displays a floor plan image of the floor where the fire started, with a fire mark F and terminal marks M1, M2, etc., added to the location of the fire and the location of the terminal, as shown in Fig. 5. In Fig. 5, the thick circle mark (M2) indicates the location of the user.
After that, the same process as the normal process shown in Fig. 3(a) is executed (step S36), and the process returns to step S32. By the normal process in step S36, a floor plan image as shown in Fig. 4, in which a mark M indicating the location of the terminal is displayed, is displayed on the display unit of the general terminal. When a fire has broken out on the same floor, in addition to the mark M indicating the location of the terminal, map information with information on the evacuation direction and a fire mark may be transmitted and displayed.

In addition, in the evacuation personnel identification system of this embodiment, when a fire occurs, the floor plan image showing marks M indicating the locations of mobile terminals other than special terminals and general terminals displays temporary evacuation sites G outdoors or outside the monitored area and the number of people who have evacuated, as shown in FIG. 6. Furthermore, when there are multiple temporary evacuation sites, each temporary evacuation site can be linked to the portable beacon brought there and registered in the database 41 of the location information server 40, so that the number of people who have evacuated from each temporary evacuation site can be displayed on the map in a comprehensible manner.

The temporary evacuation site G can be arbitrarily set on, for example, an administrator operation screen (see FIG. 7) of the location information server 40.
Specifically, first, the operation unit of the location information server 40 is operated to display an administrator operation screen for setting a temporary evacuation site on the display unit of the location information server 40. Then, when the "temporary evacuation site setting mode" is selected on this administrator operation screen, the mode is switched to the temporary evacuation site setting mode, for example, as shown in FIG.
Here, when a floor to be used as a temporary evacuation site is selected, a floor plan image of the selected floor is displayed, and a desired area within the floor plan image is designated as the temporary evacuation site G.

Next, the user inputs the name of the designated location, and if there are no problems, clicks the "Complete" button. This causes the designated and input information to be stored in the database 41 as temporary evacuation location information for the building.
In this way, in the evacuation personnel identification system of this embodiment, the location information server 40 (or the fire information server 80) can store temporary evacuation sites that can be arbitrarily set by the user and transmit information notifying the temporary evacuation sites to the target mobile terminal 20. Therefore, it is possible to inform the holders of the mobile terminal 20 (general terminal users, the head of a private fire brigade, members of the private fire brigade, etc.) of the temporary evacuation sites.

Furthermore, as shown in Fig. 8, the mark indicating the temporary evacuation site can be moved by swiping a finger on the temporary evacuation site G. This allows the temporary evacuation site to be changed even if the initially set temporary evacuation site becomes unusable due to the spread of a fire, etc. Also, by displaying the number of people who have completed evacuation for each temporary evacuation site, it becomes possible to visually grasp how many people have evacuated to which area of the building.
In addition, the configuration may be such that when the temporary evacuation site G is tapped with a finger, information such as the names of the evacuees gathered at the temporary evacuation site G is displayed in a speech bubble or the like.

Furthermore, a list of mobile terminals (users) that have completed evacuation and a list of mobile terminals (users) that have not completed evacuation may be displayed based on the identification information of each of the portable beacons 10A and the fixed beacons 10B and the information of the mobile terminal 20 that has transmitted the identification information. This allows for a quick grasp of information such as who has evacuated to multiple temporary evacuation sites and who has not yet completed evacuation. Here, if the object to be monitored is an office building, a time attendance system may be connected to the location information server 40 to enable acquisition of attendance/vacation information.
This makes it possible to avoid mistakenly identifying employees who are on vacation or out of the office as those who were left behind in the evacuation from the list of incomplete evacuation mobile terminals (users). Each user may be able to input information on their own and others' mental and physical condition (safe, slightly injured, waiting for ambulance transport, transported by ambulance, etc.) using their mobile terminal. This allows the status of each employee to be understood on the floor plan or the list of completed evacuation mobile terminals (users), etc., and can be used for prompt first aid and determining the priority of work.

Although the present invention has been described above based on the embodiments and modified examples, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the gist of the present invention. For example, in the above embodiment, a mobile terminal 20 is equipped with a location information app having a function for displaying the location of the terminal itself and a function for grasping the number of people at a temporary evacuation site when a disaster occurs. However, the location display function and the function for grasping the number of people at a temporary evacuation site of the location information app may be realized as part of the function of a disaster prevention support app that has a function for supporting the activities of a self-defense fire brigade, such as a fire chief setting roles for firefighters and issuing instructions for checking fires and extinguishing activities, and firefighters receiving instructions making reports. In addition, the location information app may be provided with a function for displaying an input screen on which the terminal owner can input information on his or her physical and mental condition (safe, slightly injured, awaiting emergency transport, etc.), thereby enabling more precise information to be obtained.

In addition, in the above embodiment, a system was described in which a portable beacon 10B having the same functions as the fixed beacon 10A was used. However, the portable beacon 10B may have a GPS radio wave receiving function and a wireless communication function in addition to a beacon signal transmitting function, so that even if a temporary evacuation site is not registered in advance, or if a temporary evacuation site that has already been set is later changed and moved, a mark indicating the temporary evacuation site and information regarding the number of evacuees can be displayed in an appropriate position on the map screen (the exact position of the portable beacon relative to the building) so that the number of people who have evacuated can be identified.
In the above embodiment, the portable transmitter has the same configuration as the stationary transmitter, but a mobile terminal may be used instead of the transmitter. In this case, a specific mobile terminal is linked to a temporary evacuation site, and a mobile terminal that has communicated with the specific mobile terminal can be determined to be in the temporary evacuation site.

Furthermore, in the above embodiment, the beacon 10 has only the function of transmitting a beacon signal, but the beacon may have the function of receiving wireless signals or radio waves from the mobile terminal 20 or the like and the function of transmitting the received information to a server via radio or wire. In this case, a radio wave transmitting tag may be carried or attached to a user or an object, and the tag information may be received by the beacon and transmitted to the location information server 40. Also, the radio waves of the mobile terminal may be received and transmitted to the location information server 40.
In the above embodiment, the system using positioning by a beacon is exemplified as the system for determining the number of people during evacuation, but the system is not limited to this and may be a system using positioning by other methods such as IMES (Indoor MEssaging System). That is, the transmitter is not limited to the beacon 10 and may be, for example, an IMES transmitter.

In addition, in the above embodiment and modified example, the system has been described as one that grasps the number of people at a temporary evacuation site, but it may also be used for a wide-area evacuation site instead of a temporary evacuation site. This makes it possible to grasp the number of evacuees who are moving together when moving to or arriving at a wide-area evacuation site, to grasp who the evacuees are with within the wide-area evacuation site when there are multiple portable beacons, and to grasp the number of evacuees at each wide-area evacuation site when there are multiple portable beacons and multiple wide-area evacuation sites have been set. Furthermore, since the head of the self-defense fire brigade or the disaster prevention center can grasp the number of people who have evacuated to the wide-area evacuation site, more appropriate activities can be carried out, such as searching for users who were unable to escape in time.

Temporary evacuation sites are places where evacuees temporarily gather, such as parking lots, parks, and school playgrounds, while wide-area evacuation sites are places where people evacuate to when the entire area becomes dangerous, such as large parks and university facilities. Many of these locations are outdoors, but by using this evacuation personnel identification system, it is possible to quickly identify the number of people at the time of evacuation without having to install devices to obtain location information in advance, and even if the installed devices to obtain location information cannot be used due to a power outage or other reasons, by registering information on 20 mobile devices in advance.
