The tablet terminal 22 accommodated in the rectangular recess can be operated or taken out by opening the transparent door. A cradle (not shown) for charging the tablet terminal 22 is disposed in the recess, and the tablet terminal 22 can be detachably attached to the cradle.

[0019] 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 the 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 a wireless communication device 225 of the tablet terminal 22, which will be described later.

[0021] The signal converter 216 includes a processor and a memory, and performs the following six operations by the processor executing a program stored in the memory. (1) The fire signal output as an electrical signal from the fire detector 1 is converted into an optical signal and output to the disaster prevention receiving panel 3. (2) Controlling the lighting of the red indicator light 213 in accordance with a 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, a fire pump control signal is output to the disaster prevention receiving panel 3. (4) The report signal output as an electrical signal from the tablet terminal 22 is converted into an optical signal and output to the disaster prevention receiving panel 3. (5) The response signal output as an optical signal from the disaster prevention receiving panel 3 is converted into an electrical signal and output to the tablet terminal 22. (6) Image data output as an electrical signal from the tablet terminal 22 is converted into an optical signal and output to the disaster prevention receiving panel 3.

[0022] 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 includes a display unit such as a liquid crystal display or an organic EL display, and a touch panel disposed on top of the 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 included in the housing 21.

[0023] The tablet terminal 22 performs the following five operations by the processor 221 executing a program stored in the memory 222. (1) The notification screen is constantly displayed on the touch screen 223. 4 is a diagram showing an example of a report screen. The report screen shown in the figure has a report button B1 for transmitting a report signal of a fire occurrence to the disaster prevention receiving panel 3, and an explanatory message M1 for explaining the purpose of this report button B1. (2) When the selection of the message button B1 is detected, a message signal is output to the signal converter 216. (3) When a response signal output from the signal converter 216 is received, a notification completion screen is displayed on the touch screen 223. 5 is a diagram showing an example of the report completion screen. The report completion screen shown in the figure has the above-mentioned report button B1, a response message (in other words, response information) M2 notifying that the report signal has been received by the disaster prevention receiving panel 3 and prompting the user to take a picture of the source of the fire, and a camera start button B2. (4) When selection of the camera start button B2 is detected, the camera 224 is started and a shooting screen (not shown) is displayed on the touch screen 223. (5) After photographing the source of the fire, when it is detected that a send button (not shown) has been selected, the photographed image data is output to the signal converter 216. The above is a description of the configuration of the fire hydrant device 2.

[0024] Next, the disaster prevention receiving panel 3 monitors fires in the tunnel and controls firefighting through each device connected via the line. In particular, it performs the following three operations in relation to the fire hydrant device 2. (1) When a fire signal is received from a fire hydrant device 2, a start-up signal is output to a fire pump control panel (not shown) and a control signal instructing the red indicator light 213 to flash is output to the fire hydrant device 2. (2) When a notification signal is received from the fire hydrant device 2, a start signal is output to the control panel of the fire pump, and a control signal for instructing the red indicator light 213 to blink is output to the fire hydrant device 2. In addition, a response signal is output to the fire hydrant device 2. (3) When image data is received from the fire hydrant device 2 and an operation to display the image data by an operator is detected, the image data is displayed on a display (not shown) of the disaster prevention receiving panel 3. This disaster prevention receiving panel 3 is installed, for example, in a communication equipment room.

[0025] In addition, in the above (1) and (2), when the disaster prevention receiving panel 3 receives a pump operation response signal from the fire pump control panel in response to the start-up signal, it may output a control signal to the fire hydrant device 2 instructing the red indicator light 213 to flash.

[0026] 1-2.Operation An example of the operation of the tunnel disaster prevention system described above will be described below. In particular, an example of the operation when a fire is reported will be described below with reference to the sequence diagram shown in FIG.

[0027] A report screen (see FIG. 4) is always displayed on the tablet terminal 22 of the fire hydrant device 2. It is assumed that a vehicle fire occurs in the tunnel in this situation, and the report button B1 on the report screen is selected by the person who found the fire. When the tablet terminal 22 detects the selection of the report button B1 (step S1), it outputs a report signal to the signal converter 216 (step S2). The signal converter 216 that receives this report signal converts the report 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 receives this report signal outputs a response signal to the signal converter 216 (step S5). The signal converter 216 that receives this response signal converts the response signal from an optical signal to an electrical signal (step S6) and outputs it to the tablet terminal 22 (step S7). The tablet terminal 22 that receives this response signal displays a report completion screen (see FIG. 5) on the touch screen 223 (step S8). This report completion screen includes a response message M2 notifying that the report signal has been received by the disaster prevention receiving panel 3. When the caller sees this response message M2, he or she can know that his or her report has been received by the disaster prevention receiving panel 3 (in other words, that his or her report has been accepted by the tunnel administrator).

[0028] The disaster prevention receiving panel 3, which has received the notification signal, also outputs a start signal to the control panel of the fire pump to start the fire pump (step S9). After that, a control signal instructing the red indicator light 213 to blink is output to the signal converter 216 that output the notification signal (step S10). The signal converter 216, which has received this control signal, switches the illumination method of the red indicator light 213 from constant illumination to blinking (step S11). The blinking of the red indicator light 213 indicates that the fire pump is operating.

[0029] The response message M2 displayed on the tablet terminal 22 is also a message encouraging the user to take a picture of the source of the fire. It is assumed that the caller who saw this message removed the tablet terminal 22 from the housing 21 of the fire hydrant device 2 and selected the camera start button B2 on the call completion screen. When the tablet terminal 22 detects the selection of the camera start button B2 (step S12), it displays a shooting screen on the touch screen 223 (step S13). It is assumed that while this shooting screen is displayed, the caller points the lens of the camera 224 at the source of the fire, takes a picture, and selects the send button on the screen. When the tablet terminal 22 detects the selection of the 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 the image data from an electrical signal to an optical signal (step S16) and outputs the image data to the disaster prevention receiving panel 3 (step S17). When the disaster prevention receiving panel 3 receives the image data and detects the display operation of the image data by the operator (step S18), it displays the image data on the display (step S19). The operator who sees the image data can visually confirm the state of the source of the fire. The above is a description of an example of the operation when reporting a fire.

[0030] 2. Variations The above embodiment may be modified as follows: The following modifications may be combined with each other.

[0031] 2-1. Variation 1 The above-described configuration of the 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. Also, the tablet terminal 22 may be accommodated 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. Variation 2 As a mechanism for preventing theft of the tablet terminal 22, an electric lock may be attached to a transparent door covering the terminal. The electric lock may be unlocked when a report button B1 is selected on the tablet terminal 22, allowing the terminal to be removed from the housing 21. In this case, a through hole the size of the report button B1 is formed in the transparent door so that the report button B1 can be selected even when the transparent door is closed. In order to unlock the electric lock when the report button B1 is selected, the signal converter 216 of the fire hydrant device 2 unlocks the electric lock when it receives a response signal from the disaster prevention receiving panel 3. For details of the electric lock, see, for example, Japanese Patent Application Laid-Open No. 2009-270307.

[0033] 2-3. Variation 3 The camera 224 of the tablet terminal 22 may be used not only to photograph the source of the fire, but also to photograph the object to be inspected when inspecting the emergency equipment of the tunnel. The photographed image data can be transmitted to the disaster prevention receiving panel 3 and displayed, so that the status of the equipment to be inspected can be shared with personnel in the communication equipment room. Also, when the report button B1 is operated, the camera 224 may photograph the operator, and the photograph may be transmitted to the disaster prevention receiving panel 3 and displayed. This makes it possible to identify the operator if the report button B1 is operated tamperingly.

[0034] 2-4. Variation 4 The tablet terminal 22 does not necessarily have to include the camera 224. If the camera 224 is not included, the tablet terminal 22 does not necessarily have to be removable from the fire hydrant device 2, and therefore the tablet terminal 22 may be fixedly attached to the housing 21 of the fire hydrant device 2.

[0035] 2-5. Variation 5 The tablet terminal 22 and the disaster prevention receiving panel 3 may be equipped with a calling function using VoIP, enabling voice calls via the optical fiber line L between the user of the tablet terminal 22 and personnel in the communications equipment room.

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

[0037] 2-7. Variation 7 When the disaster prevention receiving panel 3 receives a report signal from a fire hydrant device 2, it may specify the installation area of ​​the device as the fire outbreak area, and output a fire outbreak signal to each fire hydrant device 2 notifying the identified fire outbreak area and the fact that a fire has occurred. The signal converter 216 of the fire hydrant device 2 that receives this fire outbreak signal converts this fire outbreak signal from an optical signal to an electrical signal and outputs it to the tablet terminal 22. The tablet terminal 22 that receives the fire outbreak signal converted into an electrical signal displays a fire outbreak message on the report screen (see FIG. 4) notifying the fact of the fire outbreak and the area where the fire has occurred. A user who sees this fire outbreak message can know the fact of the fire outbreak and the area where the fire has occurred. The disaster prevention receiving panel 3 may be configured to display on the tablet terminal 22 the nearest evacuation exit in addition to the fact that a fire has occurred and the area where the fire has started.

[0038] In another embodiment, the disaster prevention receiving panel 3 may display an evacuation direction on the tablet terminal 22 instead of the nearest evacuation exit. Here, the evacuation direction differs for each compartment in which the fire hydrant device 2 is installed, and the direction opposite to the direction from the compartment in which the fire hydrant device 2 is installed to the fire area is specified as the evacuation direction.

[0039] 2-8. Variation 8 After starting the fire pump, the disaster prevention receiving panel 3 may output a start-up completion signal to each fire hydrant device 2 notifying that the fire pump has started. The signal converter 216 of the fire hydrant device 2 that receives this start-up completion signal converts this start-up completion signal from an optical signal to an electrical signal and outputs it to the tablet terminal 22. The tablet terminal 22 that receives the start-up completion signal converted into an electrical signal displays a pump start message on the notification screen (see FIG. 4) notifying that the fire pump has started. A user who sees this pump start message can know that the fire pump has started.

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

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

[0042] 2-10. Variation 10 The fire detector 1, the fire hydrant device 2 and the disaster prevention receiving panel 3 that constitute the above-mentioned tunnel disaster prevention system may be installed as emergency equipment in general buildings other than tunnels.

[0043] 2-11. Variation 11 The signal converter 216 of the fire hydrant device 2 may cause a video explaining how to use the fire hydrant to be displayed on the tablet terminal 22 when the fire hydrant valve opening / closing lever is operated and the fire hydrant switch 214 is switched.

[0044] 2-12. Variation 12 The disaster prevention receiving panel 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 written on the license plate of the accident vehicle may be extracted and output from the image data. This makes it easier to identify the owner of the accident vehicle.

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

[0046] In controlling the display of this red indicator light image G, when the signal converter 216 receives a control signal output as an optical signal from the disaster prevention receiving panel 3, instead of controlling the lighting of the red indicator light 213 according to this control signal, it converts this control signal into an electrical signal and outputs it to the tablet terminal 22. When the tablet terminal 22 receives the control signal output from the signal converter 216, it changes the red indicator light image G included in the report completion screen from a lit state to a flashing state. This change in display notifies the caller that the fire pump is operating.

[0047] As described above, by displaying the red indicator light image G on the tablet terminal 22, it becomes unnecessary to provide the red indicator light 213 on the fire hydrant device 2. As a result, the fire hydrant device 2 can be made smaller, and power consumption is reduced.

[0048] The shape and arrangement of the red indicator light image G are not necessarily limited to the example shown in FIG. 7, and may be changed as appropriate according to the size of the touch screen 223 and the sizes and arrangements of other display elements. [Explanation of symbols]
