Description

The present invention relates to a system and program for supporting activities when a fire occurs.

Conventionally, systems that support the rescue of people who are unable to escape in time when a fire breaks out are known. For example, Patent Document 1 describes a surveillance system that has multiple cameras installed in each room, estimates the number of people in each room from images captured by the cameras, and displays an approximate number of people on a drawing of the building.

JP 2016-133938 A

This monitoring system allows users to know the approximate number of people in each room. However, it does not allow users to know what attributes the people in the rooms have. If it were possible to know whether the people in the rooms are members of the private fire brigade, for example, it would be possible to understand the status of the private fire brigade's response to the fire. Also, if it were known that there are people who are vulnerable to disasters and require assistance during evacuation, rescue operations could be carried out in a more appropriate order.

The present invention has been made in consideration of the above circumstances, and aims to make it possible to determine the attributes of the occupants in each area of a building according to pre-set attributes when displaying the number of occupants in each area of a building.
In addition, the present invention aims to set persons requiring assistance during evacuation as an attribute when displaying persons present in each area of a building, and to enable evacuation activities to be carried out using information on persons requiring assistance.

To solve the above problems, the disaster prevention support system according to the present invention includes a location information acquisition unit that acquires location information of people present in a building, an attribute information acquisition unit that acquires attribute information of the people present in the building, and a display control unit that causes a display device to display a map image showing the number of people present in each area of the building, counted by attribute, based on the acquired location information and attribute information.

In a preferred embodiment, the attribute information indicates at least one of the following types of occupants: general occupants, private fire brigade, public fire brigade, and person in need of assistance.

In a further preferred embodiment, when the number of people requiring assistance is selected by the user on the map image, the display control unit further causes the display device to display consideration information indicating the number of people required to rescue the people requiring assistance.

In a further preferred embodiment, the display control unit further causes the display device to display a list image showing the number of people requiring support and consideration information for those people for each area of the entire building.

In a further preferred embodiment, the display control unit tally up the general presence in the building and those needing assistance separately in an emergency, while tallying up the general presence in the building and those needing assistance together in peacetime.

The program of the present invention causes a computer to function as a location information acquisition unit that acquires location information of people in the building, an attribute information acquisition unit that acquires attribute information of the people in the building, and a display control unit that causes a display device to display a map image showing the number of people in the building, counted by attribute, for each area of the building, based on the acquired location information and attribute information.

According to the present invention, when displaying the number of people in each area of a building, it is possible to distinguish the attributes of the people. Furthermore, according to the present invention, it is possible to distinguish those who require assistance during evacuation from among those in the building and display information about those who require assistance, making it easier to provide support during evacuation activities.

1. Embodiment A disaster prevention support system 1 according to an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 is a block diagram showing an example of the configuration of the disaster prevention support system 1. The disaster prevention support system 1 shown in the figure includes an automatic fire alarm system 2, an indoor positioning system 3, an on-site activity support system 4, and a self-defense firefighting support system 5. The various facilities and systems included in the disaster prevention support system 1 are connected to each other so as to be able to communicate with each other via a communication line such as the Internet.

The automatic fire alarm system 2 is installed in building B, which is a fire prevention object. This automatic fire alarm system 2 includes smoke detectors installed in various locations in building B, and an R-type fire receiver installed in the disaster prevention center of building B (both not shown). The smoke detectors are connected to the fire receiver via signal lines, measure the surrounding smoke density, and transmit an analog value indicating the measured smoke density to the fire receiver. The fire receiver detects a detector alarm when the smoke density measured by the smoke detector exceeds a predetermined density and the duration of this detection exceeds a predetermined time. When a detector alarm is detected, a detector alarm signal is transmitted to the self-defense firefighting support system 5. This detector alarm signal includes the address of the smoke detector that triggered the alarm.

Next, the indoor positioning system 3 is a system for identifying the positions of people in building B. This indoor positioning system 3 includes BLE (Bluetooth (registered trademark) Low Energy) transmitters installed in various places in building B, and a position management server for managing the positions of people in the building (both not shown). The BLE transmitter periodically transmits its own transmitter ID. When the mobile device of the person in the building receives this transmitter ID, it transmits it to the position management server together with the user ID of the mobile device. When the location management server receives this transmitter ID, etc., it stores it in a database as position information in association with the user ID received from the mobile device. Note that the indoor positioning system 3 may be integrated into the self-defense fire support system 5, for example, into the position information acquisition unit 711 of the support server 7, which will be described in detail later.

The mobile devices of the people in the building mentioned here include the mobile devices 6 carried by the public fire brigade members described below, and the mobile devices 8 carried by the private fire brigade members described below. Although the public fire brigade members are not directly related to building B, they become people in building B when they rush to building B in the event of a fire or other incident.

Next, the on-site activity support system 4 is a system for supporting the activities of the public fire brigade. This on-site activity support system 4 is equipped with a mobile terminal 6 carried by the public fire brigade members. Specifically, this mobile terminal 6 is a portable information processing device such as a smartphone, tablet terminal, or wearable terminal.

Next, the self-defense firefighting support system 5 is a system for supporting the activities of the automatic fire brigade organized in building B. This self-defense firefighting support system 5 comprises a support server 7, a mobile terminal 8 carried by the self-defense fire brigade members, and a headquarters terminal 9 installed in a disaster prevention center or the like of building B. Each device will be described in detail below.

Figure 2 is a block diagram showing an example of the configuration of the support server 7. The support server 7 shown in the figure includes a processor 71 such as a CPU, a volatile memory 72 such as a DRAM, a non-volatile memory 73 such as a flash memory, and a network card 74.

Non-volatile memory 73 stores location information, information about people in the building, floor map information, event information, and report information to support the activities of the private fire brigade. Of these, location information is the location information of people in building B.

The occupant information is information about the occupants in building B. Specifically, it is the user ID, name, attribute, department, member information, and consideration information of each occupant. This information is set for the user ID, and specifically, the attribute is at least one of the following: general occupants, self-defense fire brigade, public fire brigade, and person requiring support. Note that the general occupants here are occupants who do not fall under any of the self-defense fire brigade, public fire brigade, and person requiring support. In addition, the self-defense fire brigade refers to occupants who belong to a self-defense fire organization organized in building B, and the person requiring support refers to occupants who need the support of others to evacuate from building B. Next, the member information is information indicating the unit, role, and area of responsibility to which the occupant is assigned when the occupant belongs to a self-defense fire brigade. Next, the consideration information is information indicating the number of people required to evacuate the occupant as information on what kind of support the supporter needs to provide when the occupant falls under the category of person requiring support. Specifically, this information indicates age, gender, and the type and severity of the disability.

The attributes of disabilities include, for example, the elderly, the visually impaired, the hearing impaired, the physically disabled, the intellectually disabled, the mentally disabled, and the bedridden, but can also include infants and young children, pregnant women, foreigners, and others who may require support. In addition, the criteria for targets can be people requiring care level 3 or higher, people with a grade 1 or 2 physical disability certificate, people with a rehabilitation certificate A, people with a grade 1 mental disability health and welfare certificate, and people over 70 years of age. In addition, people in building B who require evacuation support can be set as targets. In addition, the methods of support provided by supporters can be specifically set, such as accompanying the elderly depending on the situation, having the visually impaired hold the supporter's elbow with the hand that is not holding the cane, checking the hearing condition and communication method (sign language, writing, etc.) for the hearing impaired and understanding the content and method of support, providing support according to the location and degree of the disability for the physically disabled, guiding the intellectually disabled safely by holding their hand when they cannot understand what is being said, guiding the mentally disabled by speaking to them slowly and calmly, providing the necessary equipment such as a stretcher or wheelchair for those who are bedridden, and providing support from multiple supporters.

Next, the floor map information is information on the layout of disaster prevention equipment (for example, indoor fire hydrants and connected water pipes) installed in building B. The layout represented by this floor map information shows the direction and room numbers. This direction is necessary for firefighting activities, particularly when public fire brigades are conducting full-scale firefighting, to consider the direction from which to approach the fire, and is important information that will be used to give instructions to firefighters who enter the scene.

In addition, the information on the layout of disaster prevention equipment includes not only transmitters, emergency telephones, fire extinguishers, indoor fire hydrants, fire doors, and SP alarm valves used in self-defense firefighting activities within buildings, but also specific symbols (or areas) displayed at the locations of water inlets and outlets of connected water supply pipes used by public fire brigades, water inlets of connected sprinkler systems, emergency power outlets, radio connection terminals for wireless communication auxiliary devices, alternative entrances (emergency entrances), emergency elevators, open spaces for firefighting activities, and fire water supplies.

The event information is information about a fire-related event that occurred in building B. Each piece of event information consists of the content of the event that occurred and the date and time of the event.

The report information is local (in other words, hot spot) report information transmitted from the mobile terminal 8 to the support server 7. Each report information is composed of the received report content, the report location, the report date and time, the reporter's user ID, and image information. Note that the image information referred to here is still image or video data captured at the local site.
The above is a description of the support information stored in the non-volatile memory 73.

As shown in FIG. 2, the support server 7 has the functions of a location information acquisition unit 711, a resident information acquisition unit 712, a synchronization unit 713, an event notification unit 714, a report reception unit 715, and a display control unit 716. These functions are realized by the processor 71 executing a program stored in the non-volatile memory 73.

Of these functions, the location information acquisition unit 711 periodically acquires location information of people present in the building from the indoor positioning system 3 and stores it in the non-volatile memory 73.

The occupant information acquisition unit 712 acquires occupant information inputted by the headquarters terminal 9 or the like, and stores it in the non-volatile memory 73.

The synchronization unit 713 synchronizes the occupant information and floor map information stored in the mobile terminal 8 with the occupant information and floor map information stored in the support server 7. This synchronization process is executed when the position information, etc. is updated in the support server 7. When the position information, etc. is updated, the synchronization unit 713 sends a synchronization notification to the mobile terminal 8, and when it receives a response thereto from the mobile terminal 8, it sends the updated information to the mobile terminal 8.

The event notification unit 714 acquires a detector alarm signal transmitted from the automatic fire alarm system 2. When the signal is acquired, the unit identifies the location (in other words, the fire point) corresponding to the address included in the acquired signal. When the fire point is identified, the unit transmits detector alarm information, which notifies the mobile device 8 that a fire detector has been activated at the identified fire point, as a push notification.

The report receiving unit 715 receives the on-site report sent from the mobile terminal 8. The information of the received on-site report is stored in the non-volatile memory 73.

The display control unit 716 receives a screen transmission request sent from the headquarters terminal 9, generates the requested screen, and transmits it to the headquarters terminal 9. Each of the generated screens will be described later.

In addition, the display control unit 716 generates a floor map screen upon receiving a screen transmission request transmitted from the mobile terminal 6 carried by the public fire brigade personnel. At that time, the display control unit 716 generates the floor map screen based on the position information, occupant information, floor map information, and event information stored in the non-volatile memory 73. The generated floor map screen includes a facility layout diagram M1, which will be described later in detail. The display control unit 716 transmits the generated floor map screen to the mobile terminal 6.
The above is the explanation of the support server 7.

Next, the mobile terminal 8 will be described.
Specifically, the mobile terminal 8 is a mobile information processing device such as a smartphone, a tablet terminal, a wearable terminal, etc. Fig. 3 is a block diagram showing an example of the configuration of the mobile terminal 8. The mobile terminal 8 shown in the figure includes a processor 81 such as a CPU, a volatile memory 82 such as a DRAM, a non-volatile memory 83 such as a flash memory, a network card 84, a display 85 such as a liquid crystal display, a touch panel 86, and a camera 87.

The non-volatile memory 83 stores location information, occupant information, and floor map information received from the support server 7.

As shown in FIG. 3, the mobile terminal 8 includes an information update unit 811, an image capture unit 812, a report unit 813, and a display control unit 814. These functions are realized by the processor 81 executing a program stored in the non-volatile memory 83.

The photographing unit 812 is a photographing means that controls the camera 87 to photograph an image of a subject.

The reporting unit 813 is a reporting means for sending on-site reports to the support server 7.

The display control unit 814 is a display control means that generates various screens and displays them on the display 85. Each screen generated by the display control unit 814 is described below.

When the mobile terminal 8 receives the detector alarm information sent from the support server 7, the display control unit 814 generates a fire notification screen. Before explaining this fire notification screen, the process leading up to the generation of this screen will be explained.

Figure 4 is a sequence diagram showing an example of the operation of the disaster prevention support system 1 when a fire occurs. As shown in the figure, when the automatic fire alarm system 2 detects a fire in building B (step Sa1), it transmits a detector alarm signal to the support server 7 (step Sa2). When the support server 7 receives this detector alarm signal, it identifies the location (in other words, the fire point) corresponding to the address included in the received signal (step Sa3). Then, it transmits detector alarm information notifying that a fire detector has been activated at the identified fire point as a push notification to the mobile terminal 8 (step Sa4). When the mobile terminal 8 receives this detector alarm information, it executes the above program stored in the non-volatile memory 83 (step Sa5). As a result of the execution of this program, the display control unit 814 generates a fire occurrence notification screen and displays it on the display 85 (step Sa6).

Figure 5 shows an example of this fire notification screen. The fire notification screen shown in the figure includes a message indicating the location and date and time of the fire. In addition, it includes a message instructing an on-site investigation. A user of the mobile terminal 8 who sees this screen can learn the location and date and time of the fire. In addition, a user on the floor where the fire occurred will investigate the site by following the instructions on the screen.

When the user presses the OK button B1 on this fire occurrence notification screen, the display control unit 814 causes the display 85 to display a floor map screen of the fire floor based on the location information, occupant information, and floor map information received from the support server 7. Note that the floor map screen is generated by the mobile device 8 based on information stored in the non-volatile memory 83 through synchronization processing, but the floor map screen generated by the display control unit 716 of the support server 7 may be displayed in the same way as the mobile device 6.

Figure 6 shows an example of this floor map screen. The floor map screen shown in the figure includes an equipment layout diagram M1. This equipment layout diagram M1 shows the direction and room numbers. In addition, a symbol S1 indicating a fire point and a symbol S2 indicating disaster prevention equipment are arranged. Furthermore, human-shaped symbols indicating the number of people present in the building counted by attribute are arranged on a room-by-room basis (i.e., a BLE transmitter (not shown) is arranged on a room-by-room basis, and the location of the room is determined based on the transmitter ID detected by each mobile terminal 8). The symbols referred to here are specifically a symbol S3 indicating the number of general people present in the building, a symbol S4 indicating the number of private firefighters, a symbol S5 indicating the number of public firefighters, and a symbol S6 indicating the number of people requiring assistance. These symbols S3 to S6 are each a different color.

The number of people represented by each symbol S3 to S6 is calculated by tallying up the information on the transmitter ID corresponding to the user ID of the mobile terminal 8 retrieved from the indoor positioning system 3, and the user ID located at the transmitter ID of the room number as the location. For example, in a large room, two BLE transmitters can be placed at the back and front of the room, dividing the room and displaying the number of people represented by each symbol S3 to S6. Similarly, in this embodiment, the display of each symbol S3 to S6 in the hallway part of the floor map screen is not shown, but depending on the number of BLE transmitters placed, the number of people in the hallway part is displayed by each symbol S3 to S6 in two places on the left and right, or three places on the left and right and center. It is preferable to detect the positions of all people in building B, and it is necessary to place the BLE transmitters so that there are no holes.

Although the symbol S6 indicating the number of people requiring support shows the same number regardless of the type of disability or the content of support of those requiring support, for example, the type of disability or the content of support may be categorized, and a symbol may be prepared for each type to display the number of people for each type. In this case, the attribute setting for the user ID may be set to an attribute that is further subdivided into those requiring support, and the number of people may be determined by distinguishing between them.

In the facility layout diagram M1 shown in FIG. 6, these symbols S3 to S6 are arranged in the room with room number "501." These symbols S3 to S6 and their arrangement indicate that the room with room number "501" contains one general occupant, one member of the private fire brigade, one member of the public fire brigade, and one person requiring assistance. By referring to these symbols S3 to S6, the user of the mobile terminal 8 can know the number of occupants by attribute in each room. As a result, the user can grasp the status of firefighting activities, including not only the private fire brigade but also the public fire brigade, and can carry out rescue activities in the appropriate order, including those requiring assistance.

In this facility layout diagram M1, the symbol S6 for a person requiring support is displayed so that it can be selected by the user. When this symbol S6 for a person requiring support is pressed by the user, the display control unit 814 displays consideration information for the person requiring support corresponding to the pressed symbol S6. FIG. 7 is a diagram showing an example of a floor map screen on which this consideration information is superimposed. On the floor map screen shown in the figure, consideration information D1 for the person requiring support corresponding to the pressed symbol S6 is placed near the pressed symbol S6. This consideration information D1 indicates that the name of the person requiring support who is in room number "501" is "Yamada Taro" and that he uses a wheelchair. By referring to this consideration information D1, the user of the mobile terminal 8 can estimate the number of people required to rescue the person requiring support.

Similarly, the private fire brigade symbol S4 is displayed so that it can be selected by the user, and when pressed by the user, the display control unit 814 displays the name, brigade affiliation, role, area of responsibility, etc. of the private fire brigade member corresponding to the pressed symbol S4, allowing the user to understand what role the member is playing in that room.

Note that the floor map screen shown in Figure 7 only displays consideration information D1 for one person, because there is only one person requiring support in room number "501." If there are multiple people requiring support in that room, multiple pieces of consideration information D1 corresponding to those multiple people requiring support will be displayed.

The floor map screen shown in Figures 6 and 7 further includes a floor list L1. This floor list L1 is a pull-down menu for selecting the floor to be displayed. When a floor is selected by the user in this floor list L1, the display control unit 814 displays an equipment layout diagram M1 of the selected floor.

The floor map screen further includes tabs T1 to T4 as a fixed menu bar. Of these tabs T1 to T4, tab T1 is a button for instructing a transition to the main screen. When the user presses this tab T1, the display control unit 814 causes the main screen to be displayed on the display 85. The functions of the displayed main screen consolidate the functions necessary for self-defense firefighting activities, and can transition to a local situation report (similar to tab T2), a planar map display (similar to tab T3), an action instruction display, a call to a disaster prevention center, etc., but as they are not directly related to the present invention, their explanation will be omitted.

Tab T2 is a button for instructing a transition to a photography screen. When this tab T2 is pressed by the user, the display control unit 814 causes the photography screen to be displayed on the display 85. The photography screen that is displayed will be described later.

Tab T3 is a button for instructing a transition to the floor map screen illustrated in FIG. 6. When this tab T3 is pressed by the user, the display control unit 814 causes the floor map screen to be displayed on the display 85.

However, during normal times, this tab T3 cannot be selected, except by certain authorized users. Therefore, the floor map screen cannot be viewed by anyone other than those few users. This is to protect the personal information of those present in the building, such as location information and consideration information. Note that normal times here refer to a time when there is no fire in building B. Conversely, an emergency refers to a time when there is a fire in building B.

Next, tab T4 is a button for instructing the transition to an action instruction screen. An action instruction here refers to an instruction for self-defense firefighting activities sent in accordance with a role. When this tab T4 is pressed by a user, the display control unit 814 generates an action instruction screen and displays it on the display 85. The function of the displayed action instruction screen is not directly related to the present invention, so its description is omitted.

The tabs T1 to T4 described above are also included in the shooting screen described below.

Next, the shooting screen that is displayed when tab T2 is pressed will be described. FIG. 8 is a diagram showing an example of this shooting screen. The shooting screen shown in the figure includes a video P1 captured by the camera 87, a photo capture button B2, and a video capture button B3. In addition, a message instructing the user to capture images of the site is included. When the user presses the photo capture button B2 on this shooting screen, the shooting unit 812 captures a still image of the subject being displayed. After the still image is captured, the display control unit 814 causes a report screen to be displayed on the display 85.

Figure 9 is a diagram showing an example of this report screen. The report screen shown in the figure includes a floor list L2, report buttons B41 to B44, and a retake button B5. Of these display elements, the floor list L2 is a pull-down menu for selecting a report location. The report buttons B41 to B44 are buttons for selecting report content. When a floor is selected in the floor list L2 and one of the report buttons B41 to B44 is selected on that floor, the report unit 813 transmits a field report to the support server 7. The transmitted field report includes the captured image information, the selected report location, the selected report content, and the user ID of the reporter. The floor list L2 is automatically set to a floor based on a fire alarm signal, and the user can select a report location according to need. Here, the automatically set floor list L2 may be the floors the user is responsible for. In addition, if the floor is large, the floor may be divided and each may be selected.

The retake button B5 is a button for redoing the image capture. When the user presses this retake button B5, the captured still image is discarded, and the display control unit 814 displays the image capture screen again.

Next, we will explain the process when shooting video. Figure 10 shows an example of the process flow when shooting video.

When the user presses the video recording button B3 on the shooting screen shown in FIG. 8 (step Sb1), the shooting unit 812 starts video recording and timing of the displayed subject (step Sb2). After that, the shooting unit 812 waits until 5 seconds have passed (NO in step Sb3), and when 5 seconds have passed (YES in step Sb3), it ends video recording (step Sb4). Here, the reason why video recording is automatically ended after 5 seconds is to prevent video recording from taking a long time. In general, it is difficult to judge the timing to end video recording, and it tends to take a long time. Therefore, in this embodiment, the number of seconds cannot be selected or the stop operation is not possible, and the shooting time is limited to 5 seconds, thereby preventing the trouble of shooting and the prolongation of the shooting time. By preventing the shooting time from being prolonged, it is possible to prevent delays in reporting to the field, and ultimately to prevent delays in reporting to the public fire brigade (so-called 119 calls). In addition, by simplifying the operation, it is not necessary to take time until the start of shooting without having to worry about the shooting operation. Furthermore, with a five-second video recording time, compared to still images, it is possible to capture not only the flames but also the surrounding area, and the disaster prevention center that receives the report can get a detailed grasp not only of the presence or absence of flames, but also of their size and the condition of the room (location).

When the video shooting is completed, the display control unit 814 automatically displays the above-mentioned report screen on the display 85. Then, on this report screen, when a floor is selected in the floor list L2 and one of the report buttons B41 to B44 is selected, the report unit 813 transmits an on-site report to the support server 7. The transmitted on-site report includes the captured image information, the selected report location, the selected report content, and the user ID of the reporter. On the other hand, when the user presses the "Retake" button B5 on this report screen, the captured video is discarded, and the display control unit 814 displays the shooting screen again.
This concludes the description of the portable terminal 8.

Next, the headquarters terminal 9 will be described.
Specifically, the headquarters terminal 9 is an information processing device such as a desktop PC. Fig. 11 is a block diagram showing an example of the configuration of the headquarters terminal 9. The headquarters terminal 9 shown in the figure includes a processor 91 such as a CPU, a volatile memory 92 such as a DRAM, a non-volatile memory 93 such as a HDD, a network card 94, a display 95 such as a liquid crystal display, and an input device 96 such as a keyboard and a mouse.

As shown in FIG. 11, the headquarters terminal 9 has a function called a remote operation unit 911. This function is realized by the processor 91 executing a program stored in the non-volatile memory 93.

This remote operation unit 911 is a display control means that acquires various screen information from the support server 7 and displays it on the display 95, and also transmits input information output by the input device 96 to the support server 7. Below, the floor map screen, occupant list screen, and information monitoring screen displayed by this remote operation unit 911 will be described.

The floor map screen is generated by the display control unit 716 of the support server 7. At that time, the display control unit 716 generates the screen based on the location information, occupant information, floor map information, and event information stored in the non-volatile memory 73.

Figure 12 is a diagram showing an example of this floor map screen. The floor map screen shown in the figure includes the equipment layout diagram M1 described with reference to Figure 6. By referring to this equipment layout diagram M1, the user of the headquarters terminal 9 can know the number of people in each room by attribute. In addition, by selecting a symbol S6 for a person requiring support on this equipment layout diagram M1, the user can refer to the consideration information for the person requiring support corresponding to the symbol. In other words, the number of people required to rescue the person requiring support can be estimated. Therefore, the user can instruct each of the private firefighters to carry out efficient rescue activities. Similarly, by selecting a private firefighter symbol S4, the user can refer to the information for the private firefighter corresponding to the symbol. In other words, the user can understand what role the firefighters are playing in that room. Therefore, the user can grasp the status of firefighting activities.

The floor map screen shown in FIG. 12 includes the floor list L1 described with reference to FIG. 6 and FIG. 7. A user of the headquarters terminal 9 can operate this floor list L1 to select the floor to be displayed.

Next, the occupant list screen will be described. This occupant list screen is a list image showing the number of occupants and their attribute information for each area of the entire building B. This occupant list screen is generated by the display control unit 716 of the support server 7. At that time, the display control unit 716 generates the screen based on the location information, occupant information, and event information stored in the non-volatile memory 73. Note that the occupant list screen may also be generated by the support server 7 and displayed.

Figure 13 is a diagram showing an example of this occupant list screen. The occupant list screen shown in the figure has a fire symbol S1 arranged on it. The arrangement of this fire symbol S1 on the screen indicates that a fire has broken out on the fifth floor of building B. In addition, the screen has human-shaped symbols arranged by room to indicate the number of occupants tallied by attribute. The symbols referred to here are the general occupant symbol S3, the private fire brigade symbol S4, the public fire brigade symbol S5, and the person requiring assistance symbol S6, which were described with reference to Figure 6. Each of these symbols S3 to S6 is a different color.

On this screen, these symbols S3 to S6 are arranged in correspondence with the room number "501." These symbols S3 to S6 and their arrangement indicate that the room with the room number "501" contains one general occupant, one private fire brigade member, one public fire brigade member, and one person requiring assistance. By referring to these symbols S3 to S6, the user of the headquarters terminal 9 can know the number of occupants by attribute in each room. As a result, the user can grasp the status of firefighting activities and can instruct each private fire brigade member to carry out efficient rescue activities.

In addition, the screen also displays, in association with the support-requiring person symbol S6, consideration information D1 for the person requiring support that corresponds to that symbol. This consideration information D1 and its arrangement indicate that the name of the person requiring support in room number "501" is "Yamada Taro," and that he uses a wheelchair. By referring to this consideration information D1, users of the headquarters terminal 9 can estimate the number of people required to rescue the person requiring support.

The screen also displays attribute information D2 of the self-defense fire brigade member corresponding to the symbol S4, in association with the symbol. This attribute information D2 has a different background color than the consideration information D1. This attribute information D2 and its display indicate that the name of the self-defense fire brigade member in room number "501" is "Yamada Jiro," his area of responsibility is the "5th floor," and his role is "chief." By referring to this attribute information D2, users of the headquarters terminal 9 can understand what role the member is playing in that room. However, the area of responsibility and role are only presented as attribute information D2 in times of emergency; in peacetime, the department to which the member belongs is presented instead of this information.

Note that the screen only displays consideration information D1 and attribute information D2 for one person, because there is only one person requiring support and one self-defense firefighter in room number "501." If there are multiple people requiring support and multiple self-defense firefighters in the room, multiple pieces of consideration information D1 and attribute information D2 corresponding to those multiple people requiring support and multiple self-defense firefighters will be displayed.

In addition, on this screen, the attribute information of general occupants corresponding to the general occupants symbol S3 is not displayed. This is because displaying personal information of general occupants would increase the amount of information displayed, and therefore priority is given to displaying information necessary for firefighting activities.

The occupant list screen shown in FIG. 13 further includes buttons B6 to B9 for selecting whether or not to display symbols and attribute information. Of these buttons B6 to B9, button B6 is a button for selecting whether or not to display the general occupant symbol S3, button B7 is a button for selecting whether or not to display the private fire brigade symbol S4 and attribute information D2, button B8 is a button for selecting whether or not to display the public fire brigade symbol S5, and button B9 is a button for selecting whether or not to display the support-requiring person symbol S6 and consideration information D1. For example, of these buttons B6 to B9, by turning on only button B9 and turning off the other buttons B6 to B8, it is possible to check only the number of support-requiring people and consideration information for each room in the entire building B.

Next, the information monitoring screen will be described. This information monitoring screen is a screen that shows events that have occurred within building B and the history of on-site reports sent from the mobile terminal 8. This information monitoring screen is generated by the display control unit 716 of the support server 7. At that time, the display control unit 716 generates the screen based on the event information and report information stored in the non-volatile memory 73.

Figure 14 is a diagram showing an example of this information monitoring screen. The information monitoring screen shown in the figure includes a history list L3. This history list L3 is a list of events that occurred in building B and on-site reports sent from the mobile terminal 8 arranged in chronological order. In addition, the screen includes an image display area R1. This image display area R1 displays an image corresponding to a on-site report selected by the user from among the on-site reports included in the history list L3. In the example screen shown in Figure 14, the top on-site report in the history list L3 is selected and highlighted, and as a result, a video of the fire spot corresponding to this on-site report is displayed. By referring to this information monitoring screen, the user of the headquarters terminal 9 can visually know the situation at the scene. As a result, it is possible to send accurate instructions to the self-defense fire brigade members.

2. Modifications The above embodiment may be modified as follows. The following modifications may be combined with each other.

2-1. Modification 1
The indoor positioning system 3 may employ other well-known indoor positioning methods instead of the indoor positioning method using BLE. For example, the positions of people in the building may be measured using Wi-Fi (registered trademark), IMES (Indoor Messaging System), or UWB (Ultra Wideband).

2-2. Modification 2
The indoor positioning system 3 may include BLE receivers installed in various locations in the building B, BLE transmitters carried by people in the building, and a location management server for managing the locations of people in the building (all not shown). When the BLE receiver receives a transmitter ID or the like from the BLE transmitter, it transmits it to the location management server together with the receiver ID of its own terminal. When the location management server receives the receiver ID or the like, it stores it in a database in association with the transmitter ID received from the BLE transmitter as location information. The indoor positioning system 3 determines that a person is carrying a BLE transmitter that has transmitted a transmitter ID or the like at a location corresponding to the receiver ID.

2-3. Modification 3
The consideration information may indicate at least one of the following, in addition to or instead of the type of disability: the specific number of people required to rescue the person requiring assistance, the equipment required to rescue the person requiring assistance, and the level of assistance required. The level of assistance required here refers to the degree of assistance required, determined from the age, type and level of disability of the person requiring assistance. The level of assistance required is determined by comparing the age, type and level of disability of the person requiring assistance with a previously created standard.

2-4. Modification 4
In the floor map screen illustrated in FIG. 6, the number of people present in the building, which is counted by attribute, is shown by room. Alternatively, the number of people present in the building, which is counted by attribute, may be shown by aggregated section units consisting of multiple rooms. By changing the counting unit in this way, it is possible to display the numbers of people present in an easy-to-read manner, for example, when the display of symbols S3 to S6 becomes too crowded, and it is easy to grasp the number of people present in areas larger than a room. Similarly, the room may be divided into two or four parts, front and back or left and right, and the position inside the room may be displayed in detailed sections (especially in the case of a large room). The display of the number of people present in the building by transmitter ID may be performed by counting for each transmitter ID with a specific position, but it is also possible to set the display of the number of people present in one place by adding up the number of people of multiple transmitter IDs, such as by room all at once. The unit of counting may be changed according to the enlargement or reduction of the equipment layout diagram M1. For example, when the equipment layout diagram M1 is reduced to display the entire floor, the number may be counted by section, whereas when the equipment layout diagram M1 is enlarged to display only some sections, the number may be counted by room.

In the occupant list screen shown in FIG. 13, the number of occupants and attribute information tallied by attribute are shown by room. Alternatively, the number of occupants tallied by attribute may be shown by floor. By changing the unit of tally in this way, it becomes easier to grasp the number of occupants by floor. As another example, if the fire prevention object is made up of multiple buildings, the number of occupants tallied by attribute may be shown by building. The unit of tally may be switched by the user by operating a button.

2-5. Modification 5
During video shooting, the mobile terminal 8 may display a message that video shooting will automatically end in 5 seconds, or may display a countdown of the number of seconds until the end of shooting. By displaying such a message, the photographer can be made aware of the timing for the end of shooting. As a result, the photographer can capture a thorough image of the area around the fire within the limited time.

2-6. Modification 6
The floor map screen illustrated in FIG. 6 cannot be viewed during normal times except by some authorized users. Alternatively, the screen may be viewable by users other than the authorized users. In this case, however, a viewing restriction may be imposed on a part of the floor. This is because some tenants may not want the structure of the floor to be known. In addition, the display of the number of people requiring support may be omitted. This is to protect the privacy of the people requiring support. Specifically, the display control unit 814 of the mobile terminal 8 may count the general building residents and the people requiring support separately in an emergency, while counting the general building residents and the people requiring support together in normal times. By counting the general building residents and the people requiring support together in this way, the privacy of the people requiring support can be protected.

2-7. Modification 7
Some or all of the functions of the support server 7 may be realized by the mobile terminal 8 or the headquarters terminal 9. Conversely, some of the functions of the mobile terminal 8 or the headquarters terminal 9 may be realized by the support server 7. In other words, the arrangement of the functions in the self-defense fire fighting support system 5 may be changed as appropriate according to the convenience of the provider of the system.

2-8. Modification 8
The video capture time of the mobile terminal 8 is set to 5 seconds. However, this is merely an example, and the capture time may be appropriately selected between 3 seconds and 15 seconds.

2-9. Modification 9
On the floor map screen in FIG. 6, human-shaped symbols indicating the number of people present in the building, counted by attribute, are arranged by room (by transmitter ID) as location information of people present, but one symbol may be displayed for each user ID. The symbols are displayed so that the user can select them, and when the user presses the symbol, consideration information for the support-requiring person corresponding to the pressed symbol can be displayed. The positions of the support-requiring people may be displayed in parallel according to the position of the transmitter ID, but the position information corresponding to the user ID imported from the indoor positioning system 3 may be set as coordinate-like position information calculated from the reference radio wave intensity of multiple transmitter IDs, so that each person requiring consideration can be positioned on the floor map and a symbol may be displayed as a more detailed position. Note that the attribute units may be support-requiring people and other people present in the building. In this case, the number of support-requiring people who need support for evacuation can be easily known.

2-10. Modification 10
When the video shooting is finished, the mobile terminal 8 may transmit the captured image information together with the user ID of the reporter to the support server 7. The support server 7 may store information associating the user ID with the building B, identify the building B based on the received user ID, and store the captured image information as an on-site report.
