As described in Patent Document 1, Patent Document 2, and Patent Document 3 below, it is possible to quickly detect abnormalities such as traffic jams, fires, accidents, etc. occurring in the tunnel for automobiles. Various sensors and surveillance cameras are installed.
[0003]
The detection signals and monitoring video of these sensors are sent to a central monitoring and control room located at a remote location, and the controller monitors the monitoring video on the monitor screen and outputs a control command signal when necessary to tunnel. Water can be discharged from the installed water discharge pump to the fire point.
[0004]
The central monitoring control room for tunnel monitoring is configured to monitor a plurality of tunnels existing in a certain area at once, and output signals from various sensors installed in each tunnel to be monitored. The video output signals of the monitoring camera are collected in the central monitoring control room.
[0005]
In the central monitoring control room, a monitor for video monitoring to display video sent from the surveillance camera and a layout drawing of the reporting equipment, smoke exhausting equipment, water discharge pump, etc. installed in the monitored tunnel are displayed. Equipment display monitors for monitoring and guidance display monitors for displaying the operation guidance for each equipment are installed. However, if each monitor is provided exclusively for each tunnel, the number of monitors will be enormous. Therefore, the central monitoring control room has a structure that can monitor the status of each tunnel by switching a small number of monitors.
[0006]
When a sensor of a tunnel detects the occurrence of an abnormality, the control device in the central monitoring control room automatically selects the monitoring video of the tunnel in which the abnormality has occurred and displays it on the video monitoring monitor. The equipment layout is automatically displayed on the equipment display monitor, and the equipment operation guidance is automatically displayed on the guidance display monitor to support the monitoring by the controller.

And a control means for locking the operation of the other operation switch.
[0013]
With this configuration, an erroneous operation command is not issued even if an incorrect operation switch is erroneously operated, so that the psychological burden on the controller is reduced and the reliability of monitoring control is improved.
[0014]
In the tunnel monitoring device of the present invention, each of the operation switches is provided with a display lamp, and the distinction is performed by blinking the display lamp provided in the manual operation switch. And
[0015]
With this configuration, it becomes obvious at a glance which operation switch can be operated on the operation panel.

[0027]
The abnormality determination panel 40 is further provided with a plurality of fire panels 49. In this multiple fire panel 49, when multiple fires occur, for example, when there is a fire in the A tunnel and a fire also occurs in the B tunnel, the multiple fires that inform the controller of the occurrence of this multiple fire An occurrence display lamp 49a and a plurality of fire display changeover switches 49b for instructing the display switching of the monitor screen in order of each fire site when a plurality of fires occur are provided.
[0028]
The water spray control panel 50 includes a switch 51 for locking the water spray water discharge valve 21, a switch 52 for releasing the lock, and a water discharge instruction for instructing water discharge from the water spray water discharge valve 21 provided for each section. The switch 54, the water discharge stop switch 53 which instruct | indicates a water discharge stop, and the display part 55 which displays the division number used as the water discharge instruction | indication object are provided.
[0029]

Further, the water spray control panel 50 is also provided with a display 58 for displaying a water discharge time.
[0030]
FIG. 3 is a diagram showing an example of equipment layout such as ventilation equipment and fire extinguishing equipment provided in the A tunnel. A mass storage device (not shown) provided in the control console 12 is a monitoring target. The equipment arrangement data for each of the A tunnel, B tunnel,..., N tunnels is stored in advance. For example, when the sensor 20 installed in the A tunnel detects an abnormality occurrence, the abnormality occurrence detection signal is received. The arithmetic unit 17 reads the equipment arrangement data of the A tunnel from the mass storage device and displays it on the equipment display monitor 14 of FIG.
[0031]
FIG. 4 is a diagram showing operation guidance for equipment provided in the A tunnel.
When a fire occurs in tunnel A, it is possible to assist the controller by displaying on the monitor screen guidance on facility operation until the fire is extinguished.
[0032]
Since the types and number of installed facilities differ for each of the A tunnel, B tunnel,... N tunnels, the facility operation guidance data is stored in advance in the mass storage device for each of the A tunnel, B tunnel,. When an abnormality occurs, the operation guidance data of the abnormality occurrence tunnel is read from the mass storage device by the arithmetic unit 17 and displayed on the guidance display monitor 15 of FIG.
[0033]
When the operation unit 17 of FIG. 4 is displayed on the guidance display monitor 15, the arithmetic unit 17 first performs the processing steps of “alarm bell ringing”, “tunnel selection”, and “event determination” in the event detection processing procedure. In order to notify the controller that 17 is automatically executed, for example, these are displayed in red. Then, after these processes, the red display is changed to, for example, a green display to notify the controller that each process is completed, and the next process to be performed is displayed in red.
[0034]
In the example of FIG. 4, the next process to be performed is the “fire certification” process, and this fire certification is performed by the controller. Therefore, “fire certification” is displayed in a blinking manner in order to urge the controller to fire certification.
[0035]
When the arithmetic unit 17 detects that a fire has occurred in a certain section of the A tunnel, the arithmetic unit 17 displays the operation guidance of FIG. 4 on the monitor 15 and the equipment layout diagram of FIG. . At the same time, a video image of the monitoring camera 22 installed in the fire occurrence section of the A tunnel is displayed on the monitor 13a for video monitoring, and further, a monitoring camera installed in a section related to this section, for example, an adjacent section. Are displayed on the monitoring monitors 13b and 13c.
[0036]
When the controller recognizes the occurrence of a fire by looking at the images on the monitoring monitors 13a, 13b, and 13c, the fire recognition switch 43 shown in FIG. 2 is pressed. This completes the “fire recognition” processing step and proceeds to the next fire initial control procedure. Alternatively, when the controller sees the images on the monitoring monitors 13a, 13b, and 13c and determines that the fire occurrence is a false alarm, the misinformation switch 42 shown in FIG. 2 is pressed to end the subsequent fire processing steps.
[0037]
When the controller recognizes that the fire is not a false alarm and that a fire has actually occurred, the tunnel monitoring device 10 automatically executes the necessary processing steps among the processing steps shown in FIG. When the control step is reached, the controller waits for an instruction input from the operation panel 19.
[0038]
When the arithmetic unit 17 waits for an input instruction from the controller, only the switch that can be operated on the operation panel 19 blinks to notify the controller which switch is operable, and the other switches. Will lock to prevent incorrect operation. Furthermore, even if the controller accidentally presses the locked switch, the input signal is treated as an error and invalidated.
[0039]
The process of seeking the control member's judgment includes determining whether the occurrence of an abnormality is a false alarm, determining whether water spraying and ventilation control are necessary, and determining the section in which these controls are performed. . For this reason, it is necessary for the controller to respond flexibly according to the length of the tunnel, the installation facilities, and the traffic volume at that time, but when the controller makes an important decision as in this embodiment, the controller The switches corresponding to the options that can be taken are clearly indicated on the operation panel 19, so that the controller does not need to consider other options, and further, the other switches are locked, so that there is no worry of erroneous operation. A more settled decision is possible.
[0040]
Next, the operation of the arithmetic unit 17 will be described with reference to FIGS. 5 to 9 when, for example, a fire occurs in the A tunnel and a fire also occurs in the B tunnel with the tunnel monitoring apparatus having the above-described configuration.
[0041]
When the fire monitoring report, which is the first report from the tunnel A, is input to the tunnel monitoring apparatus 10 from any sensor 20 or the tunnel installation report button, the arithmetic unit 17 is as shown in FIG. 5 (a). In addition, the monitoring video is displayed on the three video monitoring monitors 13a, 13b, and 13c, the facility layout data of the A tunnel is displayed on the monitor 14, and the facility operation guidance data of the A tunnel is displayed on the monitor 15. . At this time, the “up” or “down” selection lamp 31 of the A tunnel on the control tunnel panel 30 in FIG. 2 is lit, and whether the tunnel displayed on the monitor is on the up lane side of the A tunnel. It is clearly shown whether it is the down lane side.
[0042]
At the same time, as shown in FIG. 5 (b), the arithmetic unit 17 stores the information of the first notification in the data storage area 18a for the first notification provided in the memory 18, and also notifies the information. Information of occurrence point (section), number information of monitoring camera of report occurrence point, information indicating facility layout data of A tunnel, facility operation guidance data for A tunnel, and processing described in FIG. Stores data indicating the progress of the step.
[0043]
While the controller was monitoring the fire status and fire extinguishing status of tunnel A with monitoring monitors 13a, 13b, 13c, equipment display monitor 14 and guidance display monitor 15, a fire occurred in tunnel B, It is assumed that the arithmetic unit 17 of the tunnel monitoring apparatus 10 receives this fire occurrence detection signal as a second notification.
[0044]
At this time, as shown in FIG. 6A, the arithmetic unit 17 keeps the information on the A tunnel displayed on the monitoring monitors 13a, 13b, 13c, the equipment display monitor 14, and the guidance display monitor 15. As shown in FIG. 6B, in the data storage area 18b for the second notification provided in the memory 18, the information of the second notification and the notification occurrence point (section) of the second notification are stored. Information, the number information of the monitoring camera at the reporting point of the second alert, the information indicating the equipment layout map data of the B tunnel, the equipment operation guidance data for the B tunnel, and the data indicating the progress of the guidance are stored. .
[0045]
Further, the arithmetic unit 17 blinks the plurality of fire occurrence display lamps 49a of the plurality of fire panels 49 in FIG. 2 to notify the controller that a fire has occurred in addition to the A tunnel.
[0046]
When the controller is monitoring the A tunnel, if multiple fire occurrence indicator lamps 49a are blinking displayed and it is known that a fire has occurred in another tunnel, for example, the fire processing in the A tunnel is controlled automatically. When the process is started, as shown in FIG. 7, the multiple fire display changeover switch 49b is pressed. As a result, a telegram command for instructing switching from the display of the first notification to the display of the second notification is issued to the arithmetic unit 17.
[0047]
Receiving the display switching command, the arithmetic unit 17 reads each data in the storage area 18b of the memory 18, and based on this data, reports that the location of the second notification is the B tunnel as shown in FIG. The corresponding camera number of the occurrence point is notified to the video unit 16, and the equipment layout map data of B tunnel and its operation guidance data are read from the mass storage device and transmitted to the monitors 14 and 15, respectively.
[0048]
Further, the arithmetic unit 17 instructs to turn off the display lamp 31 indicating the A tunnel in the control tunnel panel 30 of FIG. 2, and the corresponding lamp 31 in the “up” or “down” lane of the B tunnel. Turn on.
[0049]
As a result, as shown in FIG. 9, the video unit 16 displays the video image of the monitoring camera 22 installed at the notification occurrence point of the B tunnel on the monitor 13a for video monitoring, and the adjacent section of the notification occurrence point. The video captured by the monitoring camera 22 installed in the is displayed on the video monitoring monitors 13b and 13c. Further, since the facility layout diagram of the B tunnel is displayed on the monitor 14 and the facility operation guidance of the B tunnel is displayed on the monitor 15, the controller can immediately cope with the fire of the B tunnel.
[0050]
While the controller handles the B tunnel fire while monitoring it on the monitor screen, and the arithmetic unit 17 is proceeding with the control process according to the processing procedure of the equipment operation guidance for the B tunnel fire, the arithmetic unit 17 is multitasking. The processing steps that can be automatically executed in the procedure of the facility operation guidance for the fire of the tunnel A are automatically executed by the processing, and the progress status is stored and updated in the corresponding portion of the memory storage area 18a. Similarly, the progress of control for the B tunnel is also stored and updated at the corresponding location in the memory storage area 18b.
[0051]
Therefore, when the controller presses the multiple fire display changeover switch 49b again to return the monitoring target on the monitor screen to the fire of the A tunnel, the arithmetic unit 17 reads the progress of the equipment operation for the A tunnel from the memory storage area 18a and immediately It becomes possible to proceed to the next control.
[0052]
When the next control waits for an instruction input for manual operation by the controller, as described above, the arithmetic unit 17 blinks and displays only the operation switches that can input instructions for the monitoring control of the A tunnel. The operation switch is locked. By controlling the operation panel 19 in this way, the controller may erroneously input an operation command for the B tunnel for the A tunnel, or conversely, an operation command for the A tunnel may be erroneously input for the B tunnel. There is no need to worry about the input, and the monitoring control of the A tunnel and the monitoring control of the B tunnel can be switched in peace.
[0053]
In the above-described embodiment, the case where two abnormalities occur simultaneously has been described as an example. However, the case where three or more abnormalities occur simultaneously is dealt with in the same manner. In this case, every time a predetermined display changeover switch is pressed, the monitor display for each abnormality and the control destination of the operation panel 19 are cyclically switched. As described above, by fixing the operation switch for inputting the display switching instruction, it is not necessary to search for the operation switch on the operation panel, and a more prompt response is possible.
