Summary of the Invention

Problems to be Solved by the Invention

[0004] In the display of a fire receiver, the location of a fire detector is displayed in characters so that the location of the fire detector that has detected a fire can be known. However, depending only on the location information in characters, it may take time to search for the fire detector to be confirmed. In recent years, due to a shortage of manpower, the replacement of administrators has become relatively frequent. Therefore, it is desirable to make the system easy to use even for inexperienced administrators. Also, it is desired to efficiently educate new administrators. The same applies to fire prevention equipment for fires other than fire detectors. And by the administrator confirming the location where the fire prevention equipment is used, etc., the fire prevention equipment can be used quickly.

[0005] The objective of this invention is to provide a system that makes it easier to check disaster prevention equipment. [Means for solving the problem]

[0006] A fire scene display system according to one embodiment of the present invention comprises a fire prevention device and a display storage device that stores a scene image corresponding to a display code displayed on or near the fire prevention device, wherein the display storage device stores the scene image of the fire prevention device corresponding to the display code, and by taking a picture of the display code with a mobile terminal and accessing the display storage device, the scene image corresponding to the display code is transmitted from the display storage device to the mobile terminal. [Effects of the Invention]

[0007] This invention provides a system that makes it easier to check disaster prevention equipment. [Brief explanation of the drawing]

[0009] Figure 1 shows a configuration diagram including a fire scene display system in an embodiment. The fire scene display system comprises fire prevention equipment and a display storage device that stores a scene image corresponding to a display code displayed on or near the fire prevention equipment. Server 1 is a display storage device that stores the scene image for display on a mobile terminal M. Server 1 is connected to a wireless LAN device R installed in building B via the internet N, which is a network. Then, wireless communication is possible with the mobile terminal M inside building B via wireless LAN through the wireless LAN device R.

[0010] The fire prevention device 2 installed inside building B displays display code 3. Display code 3 may be displayed directly on the fire prevention device 2, or it may be displayed in the vicinity of the fire prevention device 2. Display code 3 may be a two-dimensional code, a one-dimensional code, or image-recognizable characters or symbols. It may be printed or displayed on a display device. The characters or symbols may be handwritten. Server 1 stores images of the site. The site images are taken when the fire prevention device 2 is installed, etc., and are stored in Server 1 associated with the display code 3 corresponding to the fire prevention device 2. [Examples]

[0011] As an example of fire prevention equipment 2 shown in Figure 1, a fire alarm receiver 21 is shown in Figure 2. Figure 2 is a front view of the fire alarm receiver 21 used in the fire site display system of Embodiment 1. On the front of the fire alarm receiver 21, adjacent to the area indicator 211 which indicates the fire monitoring area within building B, there is an area light 212. The area indicator 211 is a printed text display. Fire detectors (not shown) are connected to the fire alarm receiver 21, and multiple fire detectors are installed in each fire monitoring area indicated by the area indicator 211. As shown in the area indicator 211, the fire monitoring areas in Embodiment 1 are set for each floor of building B. When any fire detector detects a fire in the fire monitoring area of ​​the area indicator 211, the area light 212 adjacent to that area indicator 211 lights up. On the opposite side of each area indicator 211 from the area light 212, a two-dimensional code 31, which is an example of the display code 3 in Figure 1, is displayed.

[0012] In Example 1, Server 1 stores detection range photographs as on-site images, which are photographs of the detection range for each fire detector. These detection range photographs are taken by raising the camera and capturing the detection range from the position of the fire detector. When taking the photograph, by setting the camera towards the direction of detection of the fire detector, the approximate detection range of the fire detector can be obtained as a detection range photograph. Multiple fire detectors correspond to the area display 211 in the fire receiver 21. When any of the fire detectors corresponding to the area display 211 detect a fire, the area light 212 adjacent to that area display 211 lights up. The two-dimensional code 31 is associated with the detection range photographs of the multiple fire detectors in the area display 211.

[0013] When a fire occurs or during a fire drill, the administrator checks the detection range of the fire detectors by taking a picture of one of the 2D codes 31 attached to the fire receiver 21 shown in Figure 2 with a mobile terminal M. In Example 1, the 2D code 31 represents a URL, and the URL can be obtained by taking a picture of it with the mobile terminal M. Tapping the obtained URL on the screen of the mobile terminal M accesses server 1. Then, a photograph of the detection range of the fire detectors in the fire monitoring area corresponding to the 2D code 31 is displayed as a field image on the mobile terminal M via the browser. The administrator can check the detection range photograph to confirm the detection range of the fire detectors in the area display 211.

[0014] When displaying on-site images, such as detection range photographs, a schematic diagram of the building where the fire detectors are installed may also be displayed on the mobile terminal M. Figure 3 shows the mobile screen 4 of the mobile terminal M displaying a schematic diagram of the building in the fire on-site display system of Embodiment 1. The upper part of the mobile screen 4 is a photograph display 41 showing the detection range photograph, and the lower part is a schematic diagram of the building 42. In the schematic diagram 42, the floor of the fire monitoring area being displayed is shown on the right, and the floor plan is shown on the left. In the mobile screen 4 shown in Figure 3, the left side of the schematic diagram 42 shows the floor plan of the second floor. In addition, the photograph display 41 at the top of the mobile screen 4 displays the detection range photograph at the position of "4", which is inverted in the schematic diagram 42. This detection range photograph was sent from the server 1 to the mobile terminal M. By tapping the number in the schematic diagram 42 on the mobile terminal M, the detection range photograph at the position corresponding to the number is sent from the server 1, and this detection range photograph is switched to and displayed on the photograph display 41. This allows the administrator to check the detection range of the fire detectors in each fire monitoring area.

[0015] In the on-site display system for fires in Example 1, the detection range of the fire detector was stored in Server 1 as a detection range photo, which is a on-site image, and was displayed on the mobile terminal M by photographing the two-dimensional code 31. However, the on-site display system for fires may also be used for fire extinguishing devices and the like. For example, in the case of a fire hydrant, one or more photos of the water sprayable area, which is the area where water can be sprayed with that fire hydrant, are stored in Server 1 as on-site images. On the fire receiver, a two-dimensional code for the fire hydrant is displayed in association with the area display indicating the corresponding fire monitoring area. When this two-dimensional code is photographed with the mobile terminal M, the photo of the water sprayable area can be transmitted from Server 1 to the mobile terminal M and displayed. At the time of a fire or a disaster prevention training, by checking the water sprayable area of the fire hydrant corresponding to the area display as described above, the administrator can confirm which fire hydrants can be used for the fire site. Also, as a modification of Example 2 as a on-site image, a map showing the water sprayable area may be displayed. In the case of a water discharge device installed in a dome stadium or the like for disaster prevention equipment, a photo of the water discharge range, which is the range where water discharge is possible, is stored in Server 1, and by photographing the two-dimensional code displayed on the fire receiver, a photo of the water discharge range or a map showing the water sprayable area can be displayed on the mobile terminal M.

Example

[0016] In FIG. 4, as another example of the disaster prevention equipment 2 shown in FIG. 1, a fire hydrant 22 is shown. FIG. 4 is a front view of the fire hydrant 22 used in the on-site display system for fires in Example 2. Inside the fire hydrant 22, a fire hydrant device is provided. A two-dimensional code 32 is displayed on the front of the fire hydrant 22. In the server 1 shown in FIG. 1, one or more photos of the water sprayable area, which is the area where water can be sprayed with that fire hydrant 22, are stored as on-site images in association with the two-dimensional code 32 displayed on the front of the fire hydrant 22. Note that the two-dimensional code 32 in FIG. 4 may be affixed and displayed with a sticker or the like near the fire hydrant 22, which is the disaster prevention equipment 2.

[0017] In case of a fire or during a disaster prevention training, the administrator goes to the fire hydrant 22 and takes a picture of the two-dimensional code 32 shown in FIG. 4 with the mobile terminal M. As a result, a sprinkling area photo, which is a site image, is displayed on the mobile terminal M, and the administrator can confirm the area where the fire hydrant 22 can sprinkle water. Also, as a modification, instead of the sprinkling area photo, a map 43 showing the sprinkling area of the fire hydrant 22 may be displayed as the site image. The map 43 is a map of the surrounding area of the fire hydrant 22. In this case, the server 1 shown in FIG. 1 stores, in association with the two-dimensional code 32 displayed on the front of the fire hydrant 22, a map 43 showing the sprinkling area, which is the area where water can be sprinkled with that fire hydrant 22, as a site image. FIG. 5 shows the mobile screen 4 of the mobile terminal M on which the map 43 showing the sprinkling area is displayed in the modification of Example 2 of the on-site display system for fire. In FIG. 5, in the map 43 which is the site image, the fire hydrant is shown in black, the sprinkling area is shown by oblique lines, and characters are attached.

Example

[0018] In the on-site display system for fire of Example 1, a two-dimensional code 31 was displayed on the fire receiver 21, and by taking a picture of the two-dimensional code 31 with the mobile terminal M, a photo of the detection range of the corresponding fire detector was displayed on the mobile terminal M for the administrator to confirm. Further advancing this function, the on-site display system for fire of Example 3 conducts training for the administrator to quickly reach the installation location of the fire detector corresponding to the two-dimensional code 31. In Example 3, the two-dimensional code 31, which is the display code 3 displayed on the fire receiver 21, which is the disaster prevention device 2 shown in FIG. 1, and the on-site display codes displayed on the fire detectors 5 and 6 are used.

[0019] Figure 6 shows a bottom view of the fire detector 5 used in the fire detection system of Embodiment 3. A two-dimensional code 51, which is the field indication code, is displayed on the bottom surface of the fire detector 5. The fire detector 5 is installed on the ceiling. If the ceiling is high, the field indication code can be placed on the lower side. Figure 7 shows a modified version of the fire detector 5 in Figure 6. In this modified version, a code sticker 7 displaying a two-dimensional code 72, which is the field indication code, is attached to the wall or other surface below the fire detector 6 installed on the ceiling. The two-dimensional code 72 is a field indication code provided near fire prevention equipment. The arrow 61 displayed on the fire detector 6 in Figure 7 points to the two-dimensional code 72 corresponding to the fire detector 6. Also, the fire detector 6 corresponding to the two-dimensional code 72 is located at the point of the arrow 71 on the code sticker 7 displaying the two-dimensional code 72. The two-dimensional codes 51 and 72, which are field indication codes, may also be other field indication codes such as letters or symbols, similar to the display code 3.

[0020] While the fire detection systems in Examples 1 and 2 also provide training for administrators, the fire detection system in Example 3 provides training for administrators to quickly reach the locations of fire detectors 5 and 6 in a designated fire monitoring area. In this training, the goal is to photograph the 2D code 31 displayed next to the area indicator 211 and then confirm the fire detectors 5 and 6 at the site within a predetermined time.

[0021] The sequence for training an administrator using the fire detection system of Example 3 is described below. Figure 8 shows the sequence when no time is required for verification during training. The administrator conducting the training selects which fire monitoring area to train on the area display 211 shown in Figure 2 using the fire receiver 21. For example, to train on the fire detectors 5 and 6 located in the fire monitoring area on the second floor, the administrator takes a picture of the 2D code 31 to the right of "2nd floor" displayed on the area display 211 with the mobile terminal M (step S1).

[0022] The mobile terminal M converts the captured 2D code 31 into a URL and accesses it. The access destination is the display storage device server 1. Server 1 identifies the on-site image using the URL. In Figures 1 and 2, Server 1 identifies the on-site image of the fire detector, etc., located on the second floor of the fire alarm receiver 21 shown in Figure 2, which is the fire prevention equipment 2, in building B shown in Figure 1, and transmits it to the mobile terminal M (step S2). Then, it starts the confirmation timer (step S3).

[0023] Mobile terminal M receives the transmitted on-site image and displays it using its browser (step S4). The on-site image is a photograph of the sensing range, and is displayed using the photograph display 41 shown in Figure 3. Although not shown in Figure 8, by tapping the numbers in the building diagram 42 in Figure 3, the data for the photograph display 41 and the building diagram 42 is sent from server 1 to mobile terminal M, and the on-site image on the mobile screen 4 is switched.

[0024] Fire detectors 5 and 6 display two-dimensional codes 51 and 72, as shown in Figures 6 and 7. When the administrator photographs the two-dimensional codes 51 and 72 for the fire detectors 5 and 6 corresponding to the on-site image displayed on the mobile terminal M (step S5), the mobile terminal M converts the two-dimensional codes 51 and 72 into character codes and accesses server 1. Then, it photographs the two-dimensional codes 51 and 72 for multiple fire detectors 5 and 6 in the selected fire monitoring area and transmits the character codes. In Figure 8, the character codes are transmitted sequentially for fire detectors 5 and 6, and the two-dimensional codes 51 and 72 of the last fire detector 5 and 6 are photographed and the character code is transmitted (step S6).

[0025] When Server 1 receives the character codes corresponding to the 2D codes 51 and 72 of the last disaster prevention equipment in the district, it terminates the confirmation timer (step S7).

[0026] Next, we will explain the case where the verification takes time and is not completed within the predetermined time. Figure 9 shows the sequence when the verification takes time during training. In the sequence in Figure 9, steps S1 to S4 are the same as in Figure 8.

[0027] In Figure 9, when the on-site image is displayed in step S4, the administrator starts taking pictures of the 2D codes 51 and 72 of the fire detectors 5 and 6 using the mobile terminal M (step S8). The captured 2D codes 51 and 72 are converted into character codes, and the mobile terminal M accesses the server 1. The administrator sequentially takes pictures of the 2D codes 51 and 72 for multiple fire detectors 5 and 6 in the selected fire monitoring area.

[0028] Server 1 checks the character codes sent for the fire detectors 5 and 6 in the district. If no character codes are sent for all of the relevant fire detectors 5 and 6 within a predetermined time after the confirmation timer is activated (step S9), it sends an alarm activation signal, which is a warning signal, to the mobile terminal M (step S10).

[0029] Upon receiving the alarm activation signal, the mobile terminal M activates the alarm (step S11). Even after the alarm is activated, the administrator continues to photograph the 2D codes 51 and 72 of the disaster prevention equipment, until the 2D codes 51 and 72 of the last disaster prevention equipment, the fire detectors 5 and 6, are photographed (step S12), and the character codes are sent to the server 1.

[0030] Server 1 checks the received character codes, and when character codes for all fire detectors 5 and 6 in the selected fire monitoring area have been received, it terminates the confirmation timer and sends an alarm termination signal (step S13).

[0031] Mobile terminal M receives an alarm termination signal from server 1 and terminates the alarm (step S14).

[0032] The above explanation used the fire monitoring area on the second floor of Building B as an example. Other fire monitoring areas will be tested on the same day or on different days.

[0033] In Example 3, training was conducted to enable the administrator to quickly reach the locations of fire detectors 5 and 6 in a designated fire monitoring area. However, training can also be conducted to enable administrators to quickly reach the locations of fire hydrants, not just fire detectors 5 and 6. In this case as well, a 2D code for the fire hydrant is displayed on the fire alarm receiver, etc. Then, as shown in Figures 8 and 9, when the administrator reads the 2D code with their mobile terminal M and accesses the system, the mobile terminal M receives a photograph of the area where water can be sprayed from the server 1. The administrator uses this photograph of the area where water can be sprayed as a hint to go to the fire hydrant. Then, the training is conducted to read the 2D code 32 for fire hydrant 22, shown in Figure 4, with the mobile terminal M within a predetermined time. Training can be conducted similarly not only for fire detectors and fire hydrants, but also for other fire prevention equipment such as fire doors.

[0034] In the above embodiment, the information was displayed on the mobile device M using a browser via a URL. However, the application software for the fire scene display system could also be installed on the mobile device M, and the information could be displayed on the mobile device M using the application software.

[0035] In the above, the specific configuration is not limited to the embodiments, and any design changes, etc., that do not depart from the spirit of the present invention are also included. Furthermore, the above-described embodiments and modifications can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose and configuration.
