On the front surface of the above-mentioned fire extinguisher door 2111, a rectangular recess for housing this tablet terminal 22 is formed, and a transparent resin door is installed at the opening of this recess (all not shown). The tablet terminal 22 housed in this rectangular recess can be operated and taken out by opening this transparent door. In addition, a cradle (not shown) for charging the tablet terminal 22 is arranged in the above-mentioned recess, and the tablet terminal 22 can be detachably attached to this cradle.

[0019] Figure 3 is a block diagram showing an example of the electrical configuration of the fire hydrant device 2. As shown in the figure, the housing 21 of the fire hydrant device 2 includes a red indicator light 213, a fire hydrant switch 214, a wireless communication device 215, and a signal converter 216. In this housing 21, the signal converter 216 is connected to other components and the fire detector 1 via a line.

[0020] Among these components, the wireless communication device 215 is a wireless LAN adapter. The wireless communication device 215 performs wireless communication with the wireless communication device 225 of the tablet terminal 22 described later.

[0021] The signal converter 216 includes a processor and a memory, and the processor executes a program stored in the memory to perform the following six operations. (1) Convert the fire signal output as an electrical signal from the fire detector 1 into an optical signal and output it to the disaster prevention receiving panel 3. (2) Control the lighting of the red indicator light 213 according to the control signal for the red indicator light 213 output from the disaster prevention receiving panel 3. (3) When the fire hydrant valve opening / closing lever is operated and the fire hydrant switch 214 is switched, output a fire pump control signal to the disaster prevention receiving panel 3. (4) Convert the notification signal output as an electrical signal from the tablet terminal 22 into an optical signal and output it to the disaster prevention receiving panel 3. (5) Convert the response signal output as an optical signal from the disaster prevention receiving panel 3 into an electrical signal and output it to the tablet terminal 22. (6) Convert the image data output as an electrical signal from the tablet terminal 22 into an optical signal and output it to the disaster prevention receiving panel 3.

[0022] On the other hand, the tablet terminal 22 of the fire hydrant device 2 shown in FIG. 3 includes a processor 221, a memory 222, a touch screen 223, a camera 224, and a wireless communication device 225. Among these components, the touch screen 223 has a display unit such as a liquid crystal display or an organic EL display, and a touch panel arranged on top of this display unit. The wireless communication device 225 is a wireless LAN adapter. The wireless communication device 225 performs wireless communication with the wireless communication device 215 provided in the housing 21.

[0023] This tablet terminal 22 performs the following five operations when the processor 221 executes a program stored in the memory 222. (1) Always display a notification screen on the touch screen 223. FIG. 4 is a diagram showing an example of the notification screen. The notification screen shown in the figure has a notification button B1 for transmitting a fire occurrence notification signal to the disaster prevention receiving panel 3, and an explanatory message M1 explaining the purpose of this notification button B1. (2) When detecting the selection of the notification button B1, output a notification signal to the signal converter 216. (3) When receiving the response signal output from the signal converter 216, display a notification completion screen on the touch screen 223. FIG. 5 is a diagram showing an example of the notification completion screen. The notification completion screen shown in this figure has the above-mentioned notification button B1, a response message (in other words, response information) M2 that notifies that a notification signal has been received by the disaster prevention receiving panel 3 and prompts the shooting of the fire source, and a camera activation button B2. (4) When detecting the selection of the camera activation button B2, activate the camera 224 and display a shooting screen (not shown) on the touch screen 223. (5) After shooting the fire source, when detecting the selection of a transmission button (not shown), output the captured image data to the signal converter 216. The above is the description of the configuration of the fire hydrant device 2.

[0024] Next, the disaster prevention receiving panel 3 monitors the fire in the tunnel and performs control for fire extinguishing through each device connected via a line. Particularly in relation to the fire hydrant device 2, it performs the following three operations. (1) When receiving a fire signal from the fire hydrant device 2, output an activation signal to the control panel (not shown) of the fire extinguishing pump and output a control signal instructing the flashing of the red indicator lamp 213 to that fire hydrant device 2. (2) When receiving a notification signal from the fire hydrant device 2, output an activation signal to the control panel of the fire extinguishing pump and output a control signal instructing the flashing of the red indicator lamp 213 to that fire hydrant device 2. Also, output a response signal to that fire hydrant device 2. (3) When receiving image data from the fire hydrant device 2 and detecting a display operation of the said image data by the operator, display the said image data on the display (not shown) of the disaster prevention receiving panel 3. This disaster prevention receiving panel 3 is installed, for example, in a communication machine room.

[0025] Note that in the above (1) and (2), in response to the activation signal, when the disaster prevention receiving panel 3 receives a pump operation response signal from the control panel of the fire hydrant pump, it may output a control signal instructing the flashing of the red indicator light 213 to the fire hydrant device 2.

[0026] 1-2. Operation An operation example of the tunnel disaster prevention system described above will be described. Hereinafter, in particular, an example of the operation at the time of fire notification will be described with reference to the sequence diagram shown in FIG. 6.

[0027] A tablet-type terminal 22 of the fire hydrant device 2 always displays a notification screen (see FIG. 4). Assume that a vehicle fire occurs in the tunnel in this situation, and the discoverer selects the notification button B1 on the notification screen. When the tablet-type terminal 22 detects the selection of this notification button B1 (step S1), it outputs a notification signal to the signal converter 216 (step S2). The signal converter 216 that has received this notification signal converts this notification signal from an electrical signal to an optical signal (step S3) and outputs it to the disaster prevention receiving panel 3 (step S4). The disaster prevention receiving panel 3 that has received this notification signal outputs a response signal to the signal converter 216 (step S5). The signal converter 216 that has received this response signal converts this response signal from an optical signal to an electrical signal (step S6) and outputs it to the tablet-type terminal 22 (step S7). The tablet-type terminal 22 that has received this response signal causes a notification completion screen (see FIG. 5) to be displayed on the touch screen 223 (step S8). This notification completion screen includes a response message M2 notifying that the notification signal has been received by the disaster prevention receiving panel 3. The person who has seen this response message M2 can know that their notification has been received by the disaster prevention receiving panel 3 (in other words, their notification has been accepted by the tunnel administrator).

[0028] Upon receiving the notification signal, the disaster prevention receiver 3 also outputs an activation signal to the control panel of the fire pump to activate the fire pump (step S9). Thereafter, a control signal for instructing the flashing of the red indicator lamp 213 is output to the signal converter 216 that output the notification signal (step S10). The signal converter 216 that receives this control signal switches the lighting method of the red indicator lamp 213 from constant lighting to flashing (step S11). The flashing of the red indicator lamp 213 indicates that the fire pump is operating.

[0029] The above response message M2 displayed on the tablet terminal 22 is also a message prompting the shooting of the fire source. Assume that the informant who saw this message removed the tablet terminal 22 from the housing 21 of the fire hydrant device 2 and selected the camera activation button B2 on the notification completion screen. When the tablet terminal 22 detects the selection of this camera activation button B2 (step S12), it displays a shooting screen on the touch screen 223 (step S13). Assume that in a state where this shooting screen is displayed, the informant points the lens of the camera 224 at the fire source and takes a picture, and selects the send button on the same screen. When the tablet terminal 22 detects the selection of this send button (step S14), it outputs the captured image data to the signal converter 216 (step S15). The signal converter 216 that receives this image data converts this image data from an electrical signal to an optical signal (step S16) and outputs it to the disaster prevention receiver 3 (step S17). When the disaster prevention receiver 3 that receives this image data detects a display operation of the image data by its operator (step S18), it displays the image data on the display (step S19). The operator who saw this image data can visually confirm the state of the fire source. The above is the description of the operation example at the time of fire notification.

[0030] 2. Modification The above embodiment may be modified as follows. The following modification examples may be combined with each other.

[0031] 2-1. Modification Example 1 The configuration of the above fire hydrant device 2 is merely an example. As another configuration, for example, the shape of the housing 21 of the fire hydrant device 2 may be other than a rectangular parallelepiped. Further, the tablet terminal 22 may be housed in a recess formed in the fire hydrant door 2121 instead of the fire extinguisher door 2111. In that case, the fire hydrant device 2 does not necessarily have to include the fire extinguisher storage box 211.

[0032] 2-2. Modification Example 2 As a mechanism for preventing theft of the tablet terminal 22, an electric lock may be attached to the transparent door that covers the terminal. Then, upon selection of the reporting button B1 on the tablet terminal 22, the electric lock may be unlocked, making it possible to remove the terminal from the housing 21. In that case, a through hole the size of the reporting button B1 is formed in the transparent door so that the reporting button B1 can be selected even when the transparent door is closed. Also, in order to unlock the electric lock upon selection of the reporting button B1, the signal converter 216 of the fire hydrant device 2 unlocks the electric lock upon receiving a response signal from the disaster prevention receiving board 3. For the electric lock, refer to, for example, Japanese Patent Application Laid-Open No. 2009-270307.

[0033] 2-3. Modification Example 3 The camera 224 of the tablet terminal 22 may be used not only to photograph the fire source but also to photograph the inspection target during inspection of the tunnel emergency equipment. By transmitting the photographed image data to the disaster prevention receiving board 3 for display, the status of the equipment to be inspected can be shared with the personnel in the communication machine room. Also, when the reporting button B1 is operated, the camera 224 may photograph the operator and transmit it to the disaster prevention receiving board 3 for display. Thereby, when the reporting button B1 is operated mischievously, the operator can be identified.

[0034] 2-4. Modification Example 4 The tablet terminal 22 does not necessarily have to include the camera 224. When it does not include the camera 224, since it does not necessarily have to be removable from the fire hydrant device 2, the tablet terminal 22 may be fixedly attached to the housing 21 of the fire hydrant device 2.

[0035] 2-5. Variant Example 5 The tablet terminal 22 and the disaster prevention receiving board 3 may be provided with a call function using VoIP, enabling a voice call via the optical line L between the user of the tablet terminal 22 and the personnel in the communication machine room.

[0036] 2-6. Variant Example 6 The communication between the tablet terminal 22 and the signal converter 216 may be short-range wireless communication such as Bluetooth (registered trademark) instead of communication using a wireless LAN.

[0037] 2-7. Variant Example 7 When the disaster prevention receiving board 3 receives a notification signal from the fire hydrant device 2, it may specify the installation section of the device as the fire area and output a fire occurrence signal notifying the specified fire area and the fact of the fire occurrence to each fire hydrant device 2. The signal converter 216 of the fire hydrant device 2 that has received this fire occurrence signal converts this fire occurrence signal from an optical signal to an electrical signal and outputs it to the tablet terminal 22. The tablet terminal 22 that has received the fire occurrence signal converted into an electrical signal displays a fire occurrence message notifying the fact of the fire occurrence and the fire area on the notification screen (see FIG. 4). The user who has seen this fire occurrence message can know the fact of the fire occurrence and the fire area. In addition, the disaster prevention receiving board 3 may cause the tablet terminal 22 to display the nearest emergency exit in addition to the fact of the fire occurrence and the fire area.

[0038] As another aspect, instead of the nearest emergency exit, the disaster prevention receiving board 3 may cause the tablet terminal 22 to display the evacuation direction. Here, the evacuation direction is different for each installation section of the fire hydrant device 2, and the direction opposite to the direction from the installation section of the fire hydrant device 2 to the fire area is specified as the evacuation direction.

[0039] 2-8. Variant Example 8 The disaster prevention receiver 3 may output a startup completion signal notifying that the fire pump has been started to each fire hydrant device 2 after the fire pump is started. The signal converter 216 of the fire hydrant device 2 that has received this startup completion signal converts this startup completion signal from an optical signal to an electrical signal and outputs it to the tablet-type terminal 22. The tablet-type terminal 22 that has received the startup completion signal converted into an electrical signal displays a pump startup message notifying that the fire pump has been started on the notification screen (see FIG. 4). A user who has seen this pump startup message can know that the fire pump has been started.

[0040] In addition, after the fire pump is started, when the disaster prevention receiver 3 receives a pump operation response signal from the control panel as a response to the output of the startup signal to the fire pump control panel, the disaster prevention receiver 3 may output a startup completion signal notifying that the fire pump has been started to each fire hydrant device 2. Further, the startup completion signal and the control signal for instructing the blinking of the red indicator light 213 may be the same signal.

[0041] 2-9. Modification Example 9 The communication between the disaster prevention receiver 3 and the signal converter 216 may be electrical communication instead of optical communication.

[0042] 2-10. Modification Example 10 The fire detector 1, the fire hydrant device 2, and the disaster prevention receiver 3 constituting the above tunnel disaster prevention system may be installed as emergency facilities in general buildings other than tunnels.

[0043] 2-11. Modification Example 11 When the signal converter 216 of the fire hydrant device 2 operates the fire hydrant valve opening / closing lever and the fire hydrant switch 214 is switched, a video explaining how to use the fire hydrant may be displayed on the tablet-type terminal 22.

[0044] 2-12. Modification Example 12 The disaster prevention receiver 3 may extract and output a character string by character recognition from the image data received from the fire hydrant device 2. Specifically, for example, the character string described on the license plate of the accident vehicle may be extracted from the image data and output. This facilitates the identification of the owner of the accident vehicle.

[0045] 2-13. Modified Example 13 Instead of providing the red indicator lamp 213 in the fire hydrant device 2, an image of the red indicator lamp may be displayed on the tablet terminal 22. FIG. 7 is a diagram showing an example of a notification screen including the image G of this red indicator lamp. The notification screen shown in the figure includes the red indicator lamp image G in addition to the notification button B1 and the explanation message M1. The red indicator lamp image G included in this notification screen has an annular shape and is arranged to surround the notification button B1. Further, this red indicator lamp image G is an image representing a lit red indicator lamp. Although not shown in the figure, this red indicator lamp image G is also included in the notification completion screen.

[0046] When controlling the display of this red indicator lamp image G, when the signal converter 216 receives a control signal output as an optical signal from the disaster prevention receiver 3, instead of controlling the lighting of the red indicator lamp 213 according to this control signal, this control signal is converted into an electrical signal and output to the tablet terminal 22. When the tablet terminal 22 receives the control signal output from the signal converter 216, the red indicator lamp image G included in the notification completion screen is changed from the lit state to the blinking state. By this change in display, the notifier is notified that the fire pump is operating.

[0047] As described above, by displaying the red indicator lamp image G on the tablet terminal 22, it is not necessary to provide the red indicator lamp 213 in the fire hydrant device 2. As a result, the fire hydrant device 2 can be miniaturized and power consumption can be reduced.

[0048] Note that the shape and arrangement of the red indicator lamp image G are not necessarily limited to the example shown in FIG. 7, and may be appropriately changed according to the size of the touch screen 223 and the sizes and arrangements of other display elements.
