2. Description of the Related Art FIG. 4 is a block diagram showing an outline of a conventional tunnel disaster prevention facility. In the figure, 1 is a tunnel, and 2 is a water spray fire extinguisher (head) that sprays fire-fighting water in a mist form at intervals of, for example, 5 m in each 50 m section (K1 to K30 in this case). 3 is a water storage tank,
Reference numeral 4 is a pump for pumping water from the water storage tank 3, 5 is an automatic valve provided between the water spray extinguishing apparatus 2 and the pump 4 provided for each compartment, and 6 is an electric valve for controlling the opening and closing of the automatic valve 5. Valves 7 are various disaster prevention terminal devices, for example, disaster prevention boards that output control commands to the motor-operated valve 6. J1, J2, J3 are, for example, 1
Each monitoring range consists of 0 sections.

The conventional tunnel disaster prevention equipment is constructed as described above, and the water spray fire extinguisher 2 is used as a fire extinguisher in the tunnel.
In addition to this, a fire hydrant (not shown) is provided, and a fire detector and a manual reporter (not shown) are provided as equipment for notifying a fire, and the disaster prevention board 1 controls and monitors these disaster prevention terminal devices. . These devices are required to operate normally in the event of a fire, so they are inspected regularly.

For example, in the case of the water spray fire extinguisher device 2, it is as follows. First, from the disaster prevention board 7 side, specify the section to be inspected, for example, K1, and press the open button of the automatic valve 5.
Then, the motor-operated valve 6 opens the automatic valve 6, the pressure switch provided on the secondary side of the automatic valve 6 operates, and the water sucked up by the pump 4 from the water storage tank 3 passes through the automatic valve 5 to extinguish the water spray. It is supplied to the device 2, and the water spray extinguishing device 2 discharges water to the section K1 in the tunnel 1. On the inspection site side of the tunnel 1, it is confirmed whether water is actually discharged from the water spray extinguisher 2. In this case, the designated section, that is, the section where water is discharged is usually limited to two sections, so it takes a very long time to perform the above-mentioned inspection for all the water spray extinguishing apparatuses 2 in the tunnel 1, In addition, such inspections are usually carried out while vehicles are closed, so tunnel 1
It also takes time to stop the traffic. Therefore, at the time of normal inspection, the power of the disaster prevention panel 7 is temporarily turned off and the main software is changed to increase the water discharge section. For example, the tunnel 1 is divided into three monitoring ranges J1, J2, and J3, and a control command is sent to the water discharge section for each of the monitoring ranges to sequentially discharge water.

[0005]

In the conventional disaster prevention equipment for tunnels as described above, these monitoring ranges J1, J2,
When inspecting the water spray fire extinguisher 2 for each J3, there was a difference as to the progress of the inspection, and there were the following problems. In other words, when the recovery switch on the disaster prevention panel 7 is pressed when restoring after the completion of water discharge, the disaster prevention terminal devices in all monitoring ranges are configured to be restored, so that confirmation of water discharge is completed in the monitoring range where the inspection work is slow. The recovery operation may be performed before that. On the contrary, the early monitoring range of the inspection work does not become the above, so it is necessary to wait for a while after the completion of water discharge until the other monitoring ranges complete the inspection. If the recovery operation is performed in this way, the recovery operation will be performed simultaneously for the disaster prevention terminal devices in all ranges, so the inspection must be performed in consideration of the progress of inspection for each monitoring range. However, there is a problem that the inspection time is still required and the time for stopping the traffic becomes longer accordingly.

The present invention has been made to solve the above problems. By connecting a maintenance unit such as a personal computer to a disaster prevention panel at the time of inspection, the inspection can be performed independently of the control of the disaster prevention panel, and the inspection time can be increased. The objective is to provide tunnel disaster prevention equipment that can shorten

It should be noted that the maintenance unit 25 includes a display device 27 that displays an input from the operation unit 28.
A CPU, a ROM, and a RAM for outputting to the disaster prevention board 7 and outputting a signal from the disaster prevention board 7 to the display device 27 are provided, but not shown.

The operation of the embodiment of the present invention will be described below with reference to the flow chart of FIG. First, the disaster prevention board 7 in RAM3
Area of the area controlled and monitored by, for example, K1 to K30 in ROM2
It is read from the terminal device management unit 22 and stored in the RAM 41 (S1), and the states of various terminal devices (ON / OFF of the pressure switch, whether the fire detector is operating) are stored in the RAM 41. Next, the maintenance unit 2 on the disaster prevention board 7
Connect 5. Then, the maintenance unit 25 is activated (S2), and the range of the section to be sprayed that is desired to be inspected is input from the operation unit 28 of the maintenance unit 25. Then, the CPU 1 of the disaster prevention board 7 confirms whether or not there is an input, that is, a maintenance target section notification (S3), and then excludes the section to be inspected (maintenance target section) from the management section range of the RAM3 (S4). The maintenance target section is stored in the RAM5 (S5). Then, the operation unit 28 is used to specify a section to be discharged and input a water discharge start command which is control information for inspection (S6). Then, the water discharge start command, which is the control information for inspection of each water discharge partition unit, is stored in the RAM together with the water discharge partition.
It is stored in 23 (S7).

When the maintenance terminal status collection request is input from the operation unit 28, the CPU 1 reads the contents of the RAM 41 from the R
Collect only the parcels to be inspected stored in AM5,
It is transmitted to the maintenance unit 25 that has made the request (S9).
Then, it is checked whether or not the maintenance control end command is input (S10), and if the maintenance control end command is input, it is stored in the RAM3 so as to return the maintenance target section that has been excluded until now. Then, (S11), the maintenance target section stored in the RAM5 is cleared (S12). The above steps from S2 to S12 are operations performed by a command from the maintenance unit 25.

On the other hand, the maintenance unit 25 is not activated, and the operation section 15 of the disaster prevention panel 7 inputs an arbitrary section and a water discharge start command for the section range in the RAM 3 (S13).
Then, the water discharge start order will be issued along with RA
It is stored in M21 (S14). Next, at least RA
If the inspection control information is stored in the M21 or the RAM23 (S15), the CPU1 specifies the water discharge start command, which is the inspection control information stored in the RAM21 and the RAM23, and the section that executes the command. Because
It is determined whether or not the designated partition is in the partition range for inspection stored in RAM5 or RAM3, and when the partition range matches the partition range stored in RAM5 or RAM3, the RAM22 of RAM21 and RAM23 is stored in RAM22. Store water discharge start command and water discharge section. It should be noted that the water discharge start command of the RAM 21 or RAM 23 that does not match the partition range is cleared. The partition and RA added to the control information in this way
By comparing the sections of M5 or RAM3, the control information from the disaster prevention panel 7 and the maintenance unit 25 is prevented from controlling the disaster prevention terminal equipment outside the respective management division range. The water discharge start command stored in the RAM 22 is CP
It is sent to the terminal device management section 22 by U1 (S1
6). The terminal device management unit 22 is configured to control and monitor various disaster prevention terminal devices. In this case, the signal for opening the automatic valve 5 of the corresponding section is sent to the motor-operated valve 6, and the motor-operated valve 6 causes the automatic valve 5 to operate. When is opened, water discharge is started and the automatic valve 5
The pressure switch provided on the secondary side of the device operates, and the result is stored in the RAM 41 for storing the terminal status.

At this time, when there is a request for collecting the status of the disaster prevention terminal equipment, if the request is from the maintenance unit 25, the display device of the maintenance unit 25 which has been requested by the section of RAM41 to RAM5 storing the terminal status. Display on 27. RAM41 if requested from the disaster prevention board 7 side
From the RAM 3 to the display device 14 of the disaster prevention panel 7 (S17). When there is no request, the operation waits again until the disaster prevention panel 7 or the maintenance unit 25 operates.
Considering, for example, a case where there is a recovery command from the disaster prevention board 7, the recovery command is first stored in the RAM 21. When the control information is a restoration command, the designated partition range is the entire partition range stored in RAM3, and therefore the recovery operation is performed on the partition range stored in RAM3. However, at this time, since the partition range under inspection is excluded from RAM3, the recovery command does not reach the partition range stored in RAM5, that is, the inspection partition. RA
The recovery command stored in M21 is the designated partition, that is, RA
Together with the partition range stored in M3, it is stored in the RAM 22 to close the disaster prevention terminal equipment controlled and monitored by the terminal equipment management unit 22, for example, the released automatic valve 5.

If there is a restoration command from the maintenance unit 25, the restoration command is stored in the RAM 23, and since it matches the maintenance management partition range of the RAM 5, it is stored in the RAM 22. The restoration command stored in the RAM 22 is sent by the CPU 1 to the terminal equipment management unit 22, and the terminal equipment management unit 22 restores the disaster prevention terminal equipment such as the automatic valve 5 and the fire detector for the section area in the RAM 5. Take At this time, if there is a status collection request from the maintenance unit 25, it can be displayed by the display device 27. The above explanation is for the case where one maintenance unit 25 is connected to the disaster prevention board 7, but as shown in FIG. 1, three maintenance units 25 are connected to the disaster prevention board 7 and each section that wants to independently discharge water is monitored. If the inspection work is performed in the above-described procedure by designating each range, the recovery operation can be performed independently. However, in this case, RAM5 for the maintenance management partition range should be increased according to the number of maintenance units, or RA for each maintenance management partition range.
It is stored in a predetermined area of M5. In this way, the inspection can be performed without worrying about the progress of the inspection in other monitoring ranges, so that the inspection time can be shortened and the time for stopping the traffic of the tunnel 1 can be shortened.

In the above embodiment, the water spray fire extinguisher 2 has been described as an inspection of the disaster prevention terminal equipment. However, in addition to this, the inspection of the fire detector and the like can be performed in advance by designating the section range to be inspected by the maintenance unit 25. Needless to say, fire detectors and the like can be inspected in the same manner as the water spray fire extinguisher.

[0017]

As described above, the present invention displays the operation status of the operation unit and the disaster prevention terminal device that can input the inspection control information similar to the operation unit that inputs the inspection control information to the disaster prevention panel. When the maintenance unit is connected, for example, with a display device that can be operated, the control unit provided on the disaster prevention panel causes the control unit for the inspection of the disaster prevention terminal device in the designated section from the operation unit of the disaster prevention panel and the maintenance unit The control information for inspection of the disaster prevention terminal device of the designated section from the operation unit is output to the disaster prevention terminal device independently, and the control information for inspection from the operation unit of the disaster prevention panel is inspected by the maintenance unit. The output to the disaster prevention terminal equipment in the is stopped, and only the control information for inspection from the operation unit of the maintenance unit is output to the disaster prevention terminal equipment in the section to be inspected by the maintenance unit. When you inspect the disaster prevention terminal device by dividing the tunnel into multiple monitoring areas, you can enter the control information for inspection from the operation unit of the maintenance unit and It is possible to inspect the disaster prevention terminal equipment for the section of the monitoring range, and perform the restoration operation of the disaster prevention terminal equipment for the designated section of each monitoring range only when necessary, and care about the progress of inspection of other monitoring ranges Since the inspection can be performed without doing so, there is an effect that the inspection time can be shortened and the time for stopping the traffic in the tunnel can be shortened.
