The storage unit 22 of the mobile terminal 2 has a photo folder and a disaster prevention information folder. A photo folder is a folder for storing image files shot by the user of the terminal or another terminal. Image files stored in this folder have a photo ID, shooting date and time, shooting area, and message as attribute information. Here, the photo ID is identification information of the image file given by the support server 3 . The photographing area is an area assigned in advance to the member who is the photographer. The message is a message arbitrarily input by the member who is the photographer. On the other hand, the disaster prevention information folder is a folder for storing various disaster prevention information files. Specifically, it is a folder for storing a floor map of a fire prevention object, an equipment restoration manual, self-defense fire brigade system information, a task list of each group of the self-defense fire brigade, fixed phrases, and files of member information. Files stored in this folder have at least file name, date and time of creation, creator and version information.

When the control unit 21 of the mobile terminal 2 executes the disaster prevention support program stored in the storage unit 22, the functions of the photo report unit 211, the file acquisition unit 212, and the display control unit 213 are realized.

When a photograph is taken using the camera unit 26 and image data is generated, the photograph reporting unit 211 generates an image file containing the generated image data and attribute information. The attribute information included in this image file is information indicating the shooting date and time, the shooting area that is the area in charge of the photographer, and a message arbitrarily input by the photographer. After the image file is generated, when the user instructs transmission to the disaster prevention center, the generated image file is transmitted to the support server 3 .

When the synchronization notification is received from the support server 3, the file acquisition unit 212 determines whether or not the file to be synchronized is stored in the folder of its own terminal, and requests the same file if it is not stored. file request to support server 3. After sending the file request, when the requested file is acquired, it is stored in the folder of the own terminal.

When the display of a file is instructed by the user, the display control unit 213 causes the display unit 23 to display the file for which the display is instructed.

Next, the support server 3 is specifically a server for supporting information sharing between members of the self-defense fire brigade. FIG. 3 is a block diagram showing the configuration of this support server 3. As shown in FIG.

The storage unit 32 of the support server 3 has a photo folder and a disaster prevention information folder, like the storage unit 22 of the mobile terminal 2 .

When the control unit 31 of the support server 3 executes the disaster prevention support program stored in the storage unit 32, the functions of the photo report reception unit 311, the screen generation unit 312, the first synchronization unit 313 and the second synchronization unit 314 are realized. be done.

When the image file is received from the mobile terminal 2, the photo report reception unit 311 stores the received image file in the photo folder of its own device. At that time, a photograph ID is given as attribute information to the image file.

Upon receiving a transmission request for a photo report screen (see FIG. 6) from the headquarters terminal 4 , the screen generation unit 312 generates a photo report screen based on the information of the photo folder and transmits it to the headquarters terminal 4 . Image files reported to the support server 3 are displayed on the photo report screen generated here, and an image file to be disclosed is selected by the disaster prevention center personnel from the displayed image files. In place of the disaster prevention center personnel, another person such as a member of the main unit of the self-defense fire brigade (for example, the captain) may be selected.

Upon receiving an image file disclosure request from headquarters terminal 4, first synchronization unit 313 specifies a synchronization destination of the image file to be disclosed. Specifically, the attribute information of the image file to be released is referenced to identify the shooting area of the file. By specifying, the synchronization destination is specified. Here, the member database is a database that associates and stores identification information such as names, affiliations, roles, and areas of responsibility for each member of the self-defense fire brigade. Note that the owner of the fire prevention object may be further specified as the synchronization destination. After specifying the synchronization destination, the first synchronization unit 313 transmits a synchronization notification including the photo ID to be disclosed as a push notification to the mobile terminal 2 carried by each member. Then, when a file request is received from the mobile terminal 2 , the requested image file is read out from its own photo folder and sent to the mobile terminal 2 .

When any of the files stored in the disaster prevention information folder of its own device is updated, the second synchronization unit 314 identifies the synchronization destination of the updated file. Specifically, all members registered in the member database are specified as synchronization destinations. When the synchronization destination is specified, a synchronization notification including the file name and version information of the updated file is sent as a push notification to the portable terminal 2 carried by each identified member. Then, when a file request is received from the mobile terminal 2 , the requested image file is read from the disaster prevention information folder of its own device and sent to the mobile terminal 2 .

Next, the headquarters terminal 4 is specifically a stationary PC. FIG. 4 is a block diagram showing the configuration of this headquarters terminal 4. As shown in FIG.

The headquarters terminal 4 shown in the figure includes a control unit 41 having an arithmetic processing unit such as a CPU and a volatile memory such as a RAM, a storage unit 42 such as a storage device such as an HDD, and a display such as a liquid crystal display or an organic EL display.

When the control unit 41 of the headquarters terminal 4 executes the program stored in the storage unit 42, the functions of the screen acquisition unit 411, the display control unit 412, and the disclosure request unit 413 are realized.

When the display of the photo report screen is instructed by the disaster prevention center personnel who has access authority to the support server 3, the screen acquisition unit 411 transmits a transmission request for the photo report screen to the support server 3, and the request is transmitted from the support server 3. Get the photo report screen coming up.

The display control unit 412 causes the display unit 43 to display the photo report screen acquired by the screen acquisition unit 411 . The photo report screen will be described later.

The disclosure request unit 413 sends a disclosure request including the photo ID to be disclosed to the support server 3 when the disaster prevention center staff member selects one of the image files on the photo report screen and performs an operation to instruct disclosure. Send.

1-2. Operation Next, the operation of the disaster prevention support system 1 will be described. Specifically, an operation for sharing a report photo among members of the self-defense fire brigade and an operation for synchronizing disaster prevention information between the support server 3 and the portable terminal 2 will be described. First, the operation for sharing the report photo will be described with reference to the sequence diagram shown in FIG.

When a fire is detected in a fire prevention object, a fire receiver (not shown) installed in the fire prevention object transmits a sensor alarm signal to the support server 3 . The support server 3 that has received this sensor alert signal transmits the sensor alert information to a predetermined mobile terminal 2 . A worker A carrying a portable terminal 2A (an example of the "first terminal" according to the present invention) that has received this sensor alert information arrives at the fire source, for example. When trying to report to the center, the own terminal's disaster prevention support program is started (step Sa1). Then, the screen for photographing is displayed on the display unit 23, and the photograph of the origin of the fire is photographed (step Sa2). As a result, the photograph reporting unit 211 of the portable terminal 2A generates an image file containing the image data of the origin of the fire and the attribute information (the date and time of photography, the photography area, and the message). After the generation of this image file, when the member A instructs transmission to the disaster prevention center, the photograph reporting unit 211 transmits the generated image file to the support server 3 (step Sa3).

When the transmitted image file is received by the support server 3, the photo report reception unit 311 of the support server 3 assigns a photo ID to the received image file and stores it in the photo folder (step Sa4). . After the image file is stored, when a transmission request for a photo report screen is received from the headquarters terminal 4 (step Sa5), the screen generation unit 312 of the support server 3 generates a photo report screen based on the information of the photo folder, It is transmitted to the headquarters terminal 4 (step Sa6).

When the head office terminal 4 receives the transmitted photograph report screen, the display control unit 412 of the head office terminal 4 causes the display unit 43 to display the photograph report screen (step Sa7). FIG. 6 is a diagram showing an example of this photo report screen. The photo report screen shown in the figure has an image list 61 , a select all button 62 , a cancel all button 63 , a photo release button 64 , a cancel button 65 , period designation areas 66 A and 66 B, and a search button 67 . Among these display elements, the image list 61 has a check box 611 for selection, a shooting date/time 612, a thumbnail 613, and an enlarged display button 614 for each image file. The select all button 62 is a button for collectively selecting all image files in the image list 61 , and the all cancel button 63 is a button for collectively canceling the selection of all image files in the image list 61 . be. The photo disclosure button 64 is a button for instructing disclosure of the selected image file, and the cancel button 65 is a button for hiding the photo report screen. The period designation areas 66A and 66B are areas for designating a range of shooting dates and times as image file search conditions. It is a button for instructing. On this photo report screen, when the disaster prevention center staff selects one of the image files and selects the enlarged display button 614, the display control unit 412 enlarges and displays the selected image file. By viewing this enlarged image file, the disaster prevention center personnel can know the situation at the site. In addition, when the disaster prevention center personnel selects any image file and selects the photo disclosure button 64 on the photo report screen (step Sa8), the disclosure request unit 413 of the headquarters terminal 4 specifies the photo ID to be disclosed. A disclosure request containing the information is sent to the support server 3 (step Sa9).

When the transmitted disclosure request is received by the support server 3, the first synchronization unit 313 of the support server 3 identifies the synchronization destination of the image file to be disclosed (step Sa10). Specifically, the attribute information of the image file to be released is referenced to identify the shooting area of the file. By specifying, the synchronization destination is specified. As a result of this process, when member B is specified as a synchronization destination, the first synchronization unit 313 connects the mobile terminal 2B carried by member B (an example of a “second terminal” according to the present invention). , a synchronization notification including the photo ID to be disclosed is transmitted as a push notification (step Sa11).

When the transmitted synchronization notification is received by the mobile terminal 2B, the disaster prevention support program is activated in the mobile terminal 2B if the program is not activated (step Sa12). Then, the file acquisition unit 212 of the mobile terminal 2B searches the photo folder of its own terminal using the photo ID to be synchronized as a clue, and requests the image file if the image file to be synchronized is not stored. A file request is sent to the support server 3 (step Sa13).

When the transmitted file request is received by the support server 3, the first synchronization unit 313 of the support server 3 reads out the requested image file from its own photo folder and transmits it to the portable terminal 2B (step Sa14). ).

When the transmitted image file is received by the mobile terminal 2B, the file acquisition unit 212 of the mobile terminal 2B stores the received image file in the photo folder of the own terminal (step Sa15). After the image file is stored, when the display of the image file is instructed by member B, the display control section 213 of the portable terminal 2B causes the display section 23 to display the image file (step Sa16). By looking at the displayed image file, the member B can know the situation of the site photographed by other members before arriving at the site.
The above is the description of the operation for sharing the report photo.

According to the report photo sharing method described above, only the image file selected by the disaster prevention center personnel is shared between the mobile terminals 2 . Therefore, image files to be shared can be carefully selected. Also, the person who selects the image file to be shared is limited to only the disaster prevention center personnel who have the authority to access the support server 3 . As a result, for example, unnecessary image files are not shared among team members, and the specific situation at the site of the fire can be quickly communicated among team members.

Next, operations for synchronizing disaster prevention information between the support server 3 and the mobile terminal 2 will be described with reference to the sequence diagram shown in FIG. In the following description, as an example of disaster prevention information, it is assumed that floor maps of fire prevention objects are synchronized.

In the support server 3, when the image file of the floor map is updated, for example, by the disaster prevention center personnel who operates the headquarters terminal 4, the support server 3 updates the version information of the image file (step Sb1). After updating the version information, the second synchronization unit 314 of the support server 3 identifies the synchronization destination of the updated image file (step Sb2). Specifically, all members registered in the member database are specified as synchronization destinations. After identifying the synchronization destination, the second synchronization unit 314 sends a synchronization notification including the file name and version information of the updated image file as a push notification to the mobile terminal 2 carried by each identified member (step Sb3).

When the transmitted synchronization notification is received by the mobile terminal 2, the disaster prevention support program is activated in the mobile terminal 2 if the program is not activated (step Sb4). Then, the file acquisition unit 212 of the mobile terminal 2 searches the disaster prevention information folder of its own terminal using the file name and version information to be synchronized as clues, and if the image file to be synchronized is not stored, the same image file is retrieved. A confirmation screen (not shown) for confirming whether or not to download the file is displayed on the display unit 23 (step Sb5). When the member selects the download command button displayed on the confirmation screen (step Sb6), the file acquisition unit 212 transmits a file request for the image file to the support server 3 (step Sb7). ).

When the transmitted file request is received by the support server 3, the second synchronization unit 314 of the support server 3 reads out the requested image file from its own disaster prevention information folder and transmits it to the portable terminal 2 (step Sb8).

When the transmitted image file is received by the mobile terminal 2, the file acquisition unit 212 of the mobile terminal 2 stores the received image file in the disaster prevention information folder of the own terminal (step Sb9). After the image file is stored, when the member instructs to display the image file, the display control section 213 of the portable terminal 2 causes the display section 23 to display the image file (step Sb10).
The above is the description of the operation for synchronizing the disaster prevention information.

As described above, by synchronizing the disaster prevention information between the support server 3 and the mobile terminal 2, the user of the mobile terminal 2 can refer to the latest disaster prevention information without accessing the support server 3. can do.

2. Modifications The above embodiments may be modified as follows. The following variants may be combined with each other.

2-1. Modification 1
The operation for selecting an image file to be disclosed on the photo report screen is not limited to turning on/off the check box 611 . For example, an image file to be disclosed may be selected by on/off operation of a toggle button.

2-2. Modification 2
The synchronization destination of the image file to be disclosed may be appropriately changed so that only those who need the image file can acquire the image file. For example, a predetermined mobile terminal 2 pre-registered in the support server 3 may be used as a synchronization destination instead of the member in charge of the shooting area of the image file. Here, the mobile terminal 2 pre-registered in the support server 3 does not necessarily have to be a mobile terminal carried by the team member as long as the disaster prevention support program is installed.

As another example, the mobile terminal 2 carried by a member on the floor where the fire occurred or on the floor immediately above may be used as a synchronization destination. In this case, the first synchronization unit 313 of the support server 3 refers to the member database to identify the member who is in charge of the floor where the fire occurred or the floor directly above, thereby identifying the synchronization destination. As another example, the portable terminal 2 carried by a member belonging to the same team as the creator of the image file may be used as the synchronization destination. In this case, the first synchronization unit 313 refers to the team member database to identify a team member belonging to the same team as the creator of the image file (in other words, the photographer), thereby identifying the synchronization destination. Information about the creator of the image file may be held as attribute information of the image file, or may be managed separately by the support server 3 .

2-3. Modification 3
In the above embodiment, the synchronization destination of the image file to be published is specified based on the area assigned in advance to the photographer. You may make it specify based on. In that case, the photo reporting unit 211 of the mobile terminal 2 includes the location information of the mobile terminal 2 as the attribute information of the image file. Position information is obtained using well-known indoor positioning techniques. When specifying the synchronization destination, the first synchronization unit 313 of the support server 3 refers to the team member database and specifies the team member whose area is the shooting position of the image file to be disclosed, thereby specifying the synchronization destination. .

2-4. Modification 4
In the above-described embodiment, the report photo and the disaster prevention information are synchronized between the support server 3 and the mobile terminal 2 with the synchronization notification sent from the support server 3 as a trigger. The synchronization may be performed with a synchronization request as a trigger. In that case, the mobile terminal 2 periodically transmits a synchronization request to the support server 3 . This synchronization request includes the file name and version information of each file of disaster prevention information stored in the mobile terminal 2 . Upon receiving this synchronization request, the support server 3 determines whether or not each file of disaster prevention information stored in the mobile terminal 2 is the latest version. , the mobile terminal 2 is notified of the file as a synchronization target. The mobile terminal 2 receiving this notification displays a confirmation screen for confirming whether or not the file to be synchronized needs to be downloaded, and when the member instructs the download, the file is acquired from the support server 3 .
