Description

[Technical Field]

[0001] The present invention relates to a system for determining the number of people evacuated during evacuation, which is capable of determining 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. [Background technology]

[0002] In recent years, disaster prevention support systems have been put into practical use. These systems 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 devices carried by firefighters. One known invention relating to such a disaster prevention support system includes a support device and a terminal, in which the support device transmits location inquiry information to the terminal upon receiving abnormality information, the terminal measures and transmits its own location using a satellite positioning system upon receiving the location inquiry information, the support device determines whether the terminal is located within a facility, and stores the determination result information in a storage unit in association with the ID of the firefighter carrying the terminal, and if the stored information indicates that the terminal is located within the facility, it transmits support information relating to the abnormality to the terminal, and the terminal displays the support information on a display unit upon receiving the support information (for example, Patent Document 1).

[0003] On the other hand, in the event of a disaster such as a fire or earthquake, it may be necessary to check whether there are any residents in a building who were unable to escape. One invention related to such a user location management system involves installing a beacon device in each compartment, such as a room, of a building and repeatedly transmitting a beacon signal including a compartment ID. When a device, such as a smartphone, carried by a user using the building receives the beacon signal, the device transmits a location report to a server, including the compartment ID extracted from the beacon signal and the user's own terminal ID. The server then collects and manages user location information indicating the compartment in which the terminal is located, based on the terminal ID and compartment ID included in the location report received from the user's terminal. When a fire detection signal is received from a fire receiver, the server detects from the user location information which user terminal is located in the compartment where the fire occurred, and outputs the information on the user who was unable to escape (see Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-147439 [Patent Document 2] Japanese Patent Application Publication No. 2019-032867 Summary of the Invention [Problem to be solved by the invention]

[0005] However, while the disaster prevention support system of Patent Document 1 can support the activities of the private fire brigade, it cannot obtain information about users who are unable to escape. Meanwhile, the user location management system of Patent Document 2 can obtain information about users who are unable to escape, but it cannot obtain information about users who have evacuated from the building where the system is located to the outdoors. Furthermore, while it may be possible to determine the location of users outdoors using the GPS function of their mobile devices, users may evacuate to evacuation sites near the building, and if the GPS accuracy is low, it is not suitable for evacuation confirmation. Another issue is that unless evacuated users enable the GPS function of their mobile devices, the GPS information cannot be used to confirm evacuation. Furthermore, when evacuating from a disaster, etc., roll calls will be taken after people have evacuated to a pre-designated temporary evacuation site to check whether anyone was left behind. However, if there are many people or the temporary evacuation site is small, it will take time to take roll calls, and even in a situation where every second counts, there is a risk that it will be too late to identify anyone who was left behind.

[0006] This invention was made with an eye on the above-mentioned problems, and its purpose is to provide an evacuation personnel identification system that utilizes an indoor location information system to identify personnel who have evacuated from inside a building to 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 predetermined function in advance at any evacuation site set outdoors, and which can easily respond if the evacuation site changes. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides: A portable receiver capable of receiving radio waves serving as a marker; a radio wave transmitting tag capable of transmitting the radio waves to the receiver; a server capable of communicating with the receiver; An evacuation personnel counting system comprising: the receiver is capable of receiving radio waves from the radio wave transmitting tag and transmitting information including identification information of the radio wave transmitting tag to the server; The server When the received radio wave transmitting tag information is information from the receiver, map information indicating the temporary evacuation site and information regarding the radio wave transmitting tag located at the temporary evacuation site can be transmitted to a predetermined device, The system is configured to be able to receive abnormality information based on detection signals from sensors installed in the monitoring area, and when the abnormality information is received, to identify the location where the abnormality occurred, add information about the location of the abnormality to the map information, and transmit the information to the specified device.

[0008] 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). In the evacuation personnel tracking system configured as described above, the server identifies the location of the radio wave transmitting tag based on the radio wave transmitting tag information from the portable receiver and transmits map information indicating the location to a specified device, thereby enabling the location of the radio wave transmitting tag holder to be tracked by displaying the map information on the display of the specified device. Furthermore, by receiving information about the radio wave transmitting tag located at a temporary evacuation site transmitted by the server and displaying it on the display of a mobile device or PC (personal computer), 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 can be tracked. The display function may be a display integrated with the specified device, or may be an LCD or organic EL display, CRT, digital signage, projector, or the like connected to the specified device.

[0009] Furthermore, according to the above configuration, when an abnormality occurs in the monitored area and is detected by a sensor, the abnormality information is transmitted to the server, and the server adds information about the location of the abnormality to the map information and sends it to the mobile device. This allows the location of the abnormality to be displayed on the map displayed on the display unit, allowing the owner of the mobile device to 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 sensor for crime prevention, etc., as long as it detects an abnormality that requires evacuation and transmits abnormality information.

[0010] Preferably, the monitoring system includes a plurality of stationary receivers that are installed in the monitoring area and are capable of receiving radio waves serving as markers, The stationary receiver is capable of receiving beacon radio waves in the same frequency band as the beacon radio waves that the portable receiver is capable of receiving, the stationary receiver and the portable receiver are capable of receiving radio waves from the radio wave transmitting tag and transmitting information including identification information of the radio wave transmitting tag to the server; The server The location of the radio wave transmitting tag can be identified based on the information of the radio wave transmitting tag received from the receiver, and map information indicating the location can be transmitted; When the received radio wave transmitting tag information is information from the portable receiver, the device is configured to be able to transmit map information showing the temporary evacuation site and information about the radio wave transmitting tag located at the temporary evacuation site to the specified device.

[0011] Furthermore, preferably, the detector is a fire detector that constitutes 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 the 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 the fire to the map information and transmit the map information to the mobile terminal.

[0012] With this configuration, if a fire breaks out in the monitored area, the server adds information about the location of the fire to the map information and sends it to the mobile device, so the location of the fire can be displayed on the map displayed on the display unit, allowing the mobile device owner to determine the evacuation direction. Also, 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 the existing fire detection system can be used to notify the mobile device owner of the location of the fire and allow them to evacuate safely.

[0013] Also, preferably, a display device connected to the server is provided, The server is configured to be able to display, on the display device, map information indicating temporary evacuation sites and information relating to mobile terminals located at the temporary evacuation sites.

[0014] According to this configuration, by installing the display device in a disaster prevention center or the like, the head of the fire brigade and the disaster prevention center can grasp the number of people who have evacuated to temporary evacuation sites, enabling more appropriate activities such as searching for users who were unable to escape. Note that the display device may be a liquid crystal or organic EL display, a CRT, digital signage, a projector, or the like.

[0015] Preferably, the mobile terminal comprises a display unit and an operation unit that can be operated by a user, and when an instruction to move a symbol representing a temporary evacuation site displayed on a map displayed on the display unit in accordance with the map information is input by operating the operation unit, the mobile terminal is capable of generating information instructing the movement of the symbol and transmitting the information to the server, The server is configured to move and display the symbol on the map displayed on the display unit based on the received information instructing movement. With this configuration, if a temporary evacuation site that has already been set becomes unsuitable as an evacuation site due to the spread of a fire or other reasons, the location of the temporary evacuation site can be easily changed using a mobile terminal. [Effects of the Invention]

[0016] The evacuation personnel identification system of the present invention makes it possible to quickly identify the number of people who have evacuated from inside a building to outdoors in the event of a disaster such as a fire, earthquake, etc. Furthermore, it is possible to identify the number of people who have evacuated in the event of a disaster without having to install a device with a predetermined function in advance at any evacuation site set outdoors, and it is also effective in easily responding to changes in the evacuation site.

[0018] Hereinafter, an embodiment of the evacuation personnel tracking system according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the evacuation personnel tracking system to which the present invention is applied. In FIG. 1, the area surrounded by a solid line B represents the interior space of a building, and the areas marked with symbols E1 and E2 represent the spaces of each floor and an area partitioned by walls. As shown in FIG. 1, the evacuation personnel tracking system of this embodiment includes: a stationary beacon (transmitter) 10A disposed 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 communicates data with the mobile terminal 20 via a mobile phone base station 30 and a communication network N such as the Internet.

[0019] 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 above-mentioned multiple fire detectors 50 and 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 there is a fire. The location information server 40 and the fire information server 80 can communicate data via a communication network N. The location information server 40 and the fire information server 80 may be configured as a single support server.

[0020] The communication method of the beacon 10 that transmits a wireless signal (unique information such as a device ID or facility information) to the mobile terminal 20 can be any known communication method, such as Bluetooth (registered trademark) communication, a wireless LAN such as WiFi conforming to the IEEE 802.11 standard, infrared communication, or visible light communication. The interval at which the beacons 10A are placed is not particularly limited, but in the following description, it is assumed that the beacons 10A are placed at such a distance that the communication ranges of adjacent beacons 10A overlap each other so that the entire space within the building can be covered.

[0021] Specifically, since fire detectors 50 and sprinkler heads are 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 near these devices. The beacons 10A and 10B (hereinafter, when 10A and 10B are not distinguished from each other, they will be referred to as beacons 10) have the function of transmitting signals (signal radio waves) in the same frequency band, and may be equipped with a transmitter that periodically transmits its own identification information (device ID) via a wireless signal to the surrounding area. The signal (beacon signal) wirelessly transmitted by the beacon 10 only needs to include at least the identification information (device ID) of the beacon 10, and may further include information about the area in which it is installed. If the beacon 10A has a power switch, the beacon 10B can be one with the same specifications as the beacon 10A.

[0022] 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 a location information server 40 via a communication network N.

[0023] The memory unit of the mobile terminal 20 stores an application program (location information app) that performs the following processes: receives beacon signals wirelessly transmitted from the beacon 10 at regular intervals, extracts identification information (device ID) and the like contained in the beacon signals, detects the received radio wave strength of the beacon signals, and transmits beacon information containing 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 displays a floor plan image on the display unit that includes marks indicating the mobile terminal's own location and the location of a fire, based on 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 mobile terminal 20 receives beacon signals transmitted from a plurality of beacons 10A whose communication ranges overlap each other, the control unit of the mobile terminal 20 transmits each beacon information from the wireless communication unit to the location information server 40.

[0024] 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 (or an abnormality detection signal in the case of harmful gas) to the fire receiver 60 via the detector line 51. The fire detector 50 may be a type that adds its own installation address to the fire detection signal, or may be a type that does not add its own installation address to the fire detection signal.

[0025] 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 and the interlocking of smoke control and exhaust. Furthermore, the fire receiver 60 transmits fire information including information on the location and time of the fire occurrence together with the identification information (receiver ID) of the fire receiver 60 to the fire information server 80 via the gateway 70 and the communication network N. If 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, if 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.

[0026] The fire information server 80 includes a database 81. The database 81 stores, for example, a table that stores identification information (such as building name and address) of buildings managed by the fire information server 80 and identification information (receiver ID) of fire receivers 60 installed in the buildings 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 can execute 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.

[0027] The location information server 40 includes a database 41 that stores information on each building managed by the location information server 40 and information on each mobile terminal 20. 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 building information refers to information including 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.

[0028] Furthermore, the information on mobile terminal 20 is information including identification information (terminal ID) of mobile terminal 20, information about the user of mobile terminal 20 (such as the user's name), etc. For example, information about the user can be input on a setting screen of a location information app displayed on mobile terminal 20, and the input information is transmitted to location information server 40 together with the identification information (terminal ID) of mobile terminal 20 and stored in database 41.

[0029] When location information server 40 receives beacon information transmitted by mobile terminal 20, it calculates the location of mobile terminal 20 based on the received beacon information and information stored in database 41. It is then capable of extracting a map of the floor on which mobile terminal 20 is located from database 41, plotting the location of mobile terminal 20 on the extracted map to generate map information, and transmitting the generated map information to mobile terminal 20 via communication network N and mobile phone base station 30. As a result, a floor plan image indicating the location of mobile terminal 20 is displayed on the display unit of mobile terminal 20.

[0030] 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, and the beacon signal is received by a mobile terminal 20 located nearby and transmits beacon information to the location information server 40. Then, an image showing information about evacuees is 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.

[0031] Furthermore, when the location information server 40 receives fire information from the fire information server 80, it can execute a process of generating map information that reflects the fire location information and other information 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, and a floor plan image showing the location of the fire and the location of mobile terminal 20 may be displayed on the display screen of display device 42. Display device 42 may be a liquid crystal or organic EL display, a CRT, digital signage, a projector, or the like.

[0032] Next, an example of the procedure of the location information display process executed by the control unit of the mobile terminal 20 will be described using the flowchart shown in Fig. 2. Note that this location information display process is repeatedly executed at a fixed cycle 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).

[0033] 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, if a beacon signal is received (step S11; Yes), the beacon information including the identification information (device ID) of the beacon 10 contained in the beacon signal and the received radio wave intensity 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).

[0034] Next, it is determined whether the wireless communication unit has received map information transmitted from the location information server 40 (step S13). If map information has not been received (step S13; No), the location information display process is terminated. On the other hand, if map information has been received (step S13; Yes), an image (floor plan image) based on the map information is displayed on the display unit (step S14), and the location information display process ends. 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 step S14s 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.

[0035] In addition, instead of transmitting beacon information to the location information server 40 every time a beacon signal is received, the mobile terminal 20 may transmit beacon information based on the currently received beacon signal to the location information server 40, for example, when the identification information of the beacon 10 included in the previously received beacon signal is different from the identification information of the beacon 10 included in the currently received beacon signal.

[0036] Next, an example of a procedure for 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), an administrator-authorized terminal held by an administrator is referred to as a "special terminal," and among the mobile terminals 20 present in the building where the fire started, mobile terminals 20 other than the administrator-authorized terminal are referred to as "general terminals," and a person holding 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 it may be a fixed-type PC terminal deployed 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 may be more than just these two groups. For example, there may be a "private fire brigade member terminal" held by a private fire brigade member.

[0037] 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 location information server 40 together with the identification information (terminal ID) of the terminal and stored in 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.

[0038] 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 the 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 sent along with the fire information, and transmits the fire information to the location information server 40 together with the obtained building identification information. When a fire occurs in one of the buildings under its management (when the 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 the beacon information from the mobile terminal 20.

[0039] 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 one 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 occurred, and if a fire breaks out in one of the multiple buildings managed by the location information server 40, the fire processing (Fig. 3(b)) described below is executed, and in this fire processing, the normal processing (step S36) is executed.

[0040] 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).

[0041] 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 is marked with a mark M indicating the mobile terminal 20 at a position corresponding to the current location of the mobile terminal 20, as shown in Fig. 4. In Fig. 4, the circled numbers attached to the marks M indicate the number of people (number of mobile terminals) present at that location.

[0042] Next, an example of the procedure of 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 of 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).

[0043] In the fire processing of FIG. 3(b), first, a map of the floor on which the fire broke out 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 a 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 that it can be distinguished from other terminals. Furthermore, each mark may be displayed with a number corresponding to the number of mobile terminals 20 that have transmitted the same beacon information, to indicate how many people are present at the location.

[0044] 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., attached to the location of the fire and the location of the terminal, as shown in Figure 5. In Figure 5, the mark with a thick circle (M2) indicates the user's current location. Thereafter, the same processing as the normal processing shown in Fig. 3(a) is executed (step S36), and the process returns to step S32. As a result of the normal processing 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, map information with evacuation direction information and a fire mark added in addition to the mark M indicating the location of the terminal may be transmitted and displayed.

[0045] Furthermore, in the evacuation personnel tracking system of this embodiment, when a fire breaks out, a 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, if there are multiple temporary evacuation sites, each temporary evacuation site can be linked to the portable beacon carried there and registered in database 41 of location information server 40, thereby making it possible to display on a map the number of people who have evacuated for each temporary evacuation site in a comprehensible manner.

[0046] The temporary evacuation site G can be arbitrarily set on the administrator operation screen of the location information server 40 (see FIG. 7), for example. Specifically, first, the operation unit of the location information server 40 is operated to display an operation screen for an administrator for setting a temporary evacuation site on the display unit of the location information server 40. Then, when "Temporary evacuation site setting mode" is selected on this operation screen for an administrator, the mode switches to the temporary evacuation site setting mode, as shown in Fig. 7, for example. 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.

[0047] Next, enter the name of the designated location, and if there are no problems, click the "Done" button. This causes the designated and entered information to be stored in the database 41 as temporary evacuation location information for the building. As described above, 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 notify the temporary evacuation sites to those who possess the mobile terminal 20 (general terminal users, the head of the private fire brigade, members of the private fire brigade, etc.).

[0048] Furthermore, as shown in Figure 8, the mark indicating the temporary evacuation location can be moved by swiping or otherwise moving a finger over temporary evacuation location G. This allows the temporary evacuation location to be changed even if the initially set temporary evacuation location becomes unusable due to the spread of a fire or other reasons. Also, by displaying the number of people who have evacuated to each temporary evacuation location, it becomes possible to visually grasp how many people have evacuated to which locations in the building. In addition, the temporary evacuation site G may be configured so that when the user taps the site G 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.

[0049] Furthermore, a list of mobile terminals (users) that have completed evacuation and a list of mobile terminals (users) that have not yet 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 transmitted the identification information. This makes it possible to quickly grasp information such as who has evacuated when there are multiple temporary evacuation sites and who has not yet completed evacuation. Here, if the monitored object is an office building, a time attendance system may be connected to the location information server 40 so that attendance / vacation information can be acquired. This makes it possible to avoid mistakenly identifying employees who are on vacation or out of the office as those who were not able to evacuate from the list of incomplete evacuation mobile terminals (users). Each user may be able to input information about their own and others' physical and mental status (safe, minor injuries, waiting for ambulance transport, transported by ambulance, etc.) using their mobile terminal. This allows the status of each employee to be grasped on the floor plan or on the list of completed evacuation mobile terminals (users), which can be used for prompt first aid and determining work priorities.

[0050] While the present invention has been described above based on embodiments and modifications, it is not limited to the above embodiments and can be modified as appropriate without departing from the spirit and scope of the present invention. For example, in the above embodiment, a location information app was installed on the mobile device 20, which has a function for displaying the device's location and a function for tracking personnel at temporary evacuation shelters in the event of a disaster. However, the location information app's function for displaying the device's location and a function for tracking personnel at temporary evacuation shelters may be implemented as part of a disaster prevention support app that supports the activities of the private fire brigade, such as allowing the fire chief to assign roles to firefighters and issue commands for fire detection and firefighting activities, and for firefighters who receive commands to report. Furthermore, the location information app may be provided with a function for displaying an input screen on which the device owner can input information about their physical and mental condition (e.g., safe, slightly injured, awaiting emergency transport), thereby enabling more precise information to be acquired.

[0051] 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, but the portable beacon 10B may be one that has, in addition to the beacon signal transmission function, the function of receiving GPS radio waves and the wireless communication function, so that even if the temporary evacuation site is not registered in advance, or if a temporary evacuation site that has been set is later changed and moved, a mark indicating the temporary evacuation site and information about the 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 evacuees can be identified. In the above embodiment, the portable transmitter has been described as having the same configuration as the stationary transmitter, but a mobile terminal can be used as a transmitter. In this case, a specific mobile terminal can be linked to a temporary evacuation site, and a mobile terminal that has communicated with the specific mobile terminal can be determined to be at the temporary evacuation site.

[0052] 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 a wireless signal or radio waves from the mobile terminal 20 or the like and the function of transmitting the received information to a server via wireless or wired communication. In this case, a radio wave transmitting tag may be carried or attached to a user or an object, and the beacon may receive tag information and transmit it to the location information server 40. Alternatively, the beacon may receive radio waves from a mobile terminal and transmit it to the location information server 40. In addition, in the above embodiment, a system using positioning by a beacon is exemplified as the system for determining the number of people at the time of evacuation, but the system is not limited to this and may be a system for determining the number of people at the time of evacuation that uses 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.

[0053] In addition, while the above embodiment and modified examples have been described as a system for tracking people at temporary evacuation sites, the system may also be used for large-scale evacuation sites instead of temporary evacuation sites. This makes it possible to track evacuees traveling together when moving to or arriving at a large-scale evacuation site, to track who evacuees are with within the large-scale evacuation site when there are multiple portable beacons, and to track the number of evacuees at each large-scale evacuation site when there are multiple portable beacons and multiple large-scale evacuation sites. Furthermore, since the head of the Self-Defense Force fire brigade and the disaster prevention center can track the number of people who have evacuated to the large-scale evacuation site, they can carry out more appropriate activities, such as searching for users who were unable to escape.

[0054] Temporary evacuation sites are places where evacuees temporarily gather, such as parking lots, parks, and school grounds, while wide-area evacuation sites are large parks, university facilities, and other locations where people can evacuate when the entire area becomes dangerous. Many of these locations are outdoors, but by using this evacuation personnel tracking system, it is possible to quickly track the number of people in an evacuation without installing devices to obtain location information in advance, and even if installed devices to obtain location information become unusable due to a power outage or other reason, by registering the information on mobile devices in advance.
