  However, even if ventilation equipment such as each ventilation device installed in a long tunnel is controlled, it takes several minutes for the control result to appear as a wind direction and wind speed pattern in the tunnel. That is, after the ventilation equipment is controlled, if the wind direction and wind speed pattern obtained as a result of this control is wrong, there is a high possibility that it will be too late even if the ventilation equipment is controlled again.

  For this reason, when the controller determines how to perform the ventilation control, the controller is required to make a more careful and accurate determination. This determination must be made under various information and warnings in the event of an emergency such as the occurrence of a fire, which contributes to increasing the burden on the controller.

There is provided a control mode switch 70 for inputting whether or not to operate, and an operation control right switch 80 for selecting an operation control right.

  On the control tunnel panel 30, selection display lamps 31 are arranged for each "up" and "down" of each tunnel to be monitored. When an abnormality occurs in any of the tunnels and the arithmetic unit 17 specifies the tunnel and the abnormality occurrence section, the corresponding selection display lamp 31 is turned on and the video monitoring monitors 13a, 13b, 13c Displays the video shot by the surveillance camera installed in the generated tunnel. As a result, the controller can determine which tunnel's “up” or “down” lane the video shown on the video monitoring monitors 13a, 13b, 13c. In addition, it is good also as a structure which can select the tunnel to monitor manually by providing the selection switch with the selection display lamp 31, respectively.

  The abnormality determination panel 40 includes a display unit 41 that displays a section number of an abnormality when an abnormality occurs in the tunnel, and a false alarm switch 42 that is pressed by the controller when the controller determines that the abnormality has occurred. A fire recognition switch 43 that is pressed when the controller recognizes a fire occurrence, a fire suppression switch 44 that is pressed when the controller determines that the fire has been extinguished, and a fire recovery switch that is pressed when the controller determines that the fire has recovered 45, accident switch 46 that is pressed when the controller recognizes the occurrence of the accident, accident recovery switch 47 that is pressed when the controller determines that the accident has been recovered, and disaster prevention that is pressed when the controller determines that the disaster prevention panel has been recovered A panel recovery switch 48 is provided.

  The abnormality determination panel 40 is further provided with a plurality of fire panels 49.

Further, the water spray control panel 50 is also provided with a display 58 for displaying a water discharge time.

  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 a fire occurrence, the fire 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.

  The equipment display monitor 14 includes a touch panel. When a corresponding location on the equipment layout diagram illustrated in FIG. 3 is touched with a finger, a switch-on signal corresponding to the relevant location is transmitted from the touch panel to the arithmetic unit 17. Is done. Receiving this signal, the arithmetic unit 17 transmits an equipment on / off control signal corresponding to the signal transmitted from the touch panel to the corresponding equipment.

  FIG. 4 is a diagram showing operation guidance for equipment provided in the A tunnel. When a fire breaks out in tunnel A, the guidance for facility operation until the fire is extinguished is displayed on the monitor screen to assist the controller.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  Next, the operation of the arithmetic unit 17 when, for example, a fire has occurred in a section having the A tunnel with the tunnel monitoring apparatus having the above-described configuration will be described.

  FIG. 5 is a flowchart showing a control procedure executed by the arithmetic unit 17 when a fire occurs. In this flowchart, the process surrounded by the double line frame is a process by a controller (person).

  The arithmetic processing unit 17 performs normal operation processing in a state where no abnormality such as an accident has occurred, and enters an abnormal event detection process (step S1) when an abnormal event occurs. The abnormal event detection process is started when any of the sensors installed in the tunnel detects the occurrence of an abnormality and notifies the arithmetic unit 17 of an alarm. In addition, the controller is monitoring the monitor screen. It is also started when an abnormal occurrence is detected and the abnormal occurrence is manually input.

  When an abnormal event is detected, the arithmetic unit 17 detects a section where the abnormality has occurred (step S2). A code indicating each sensor installation location is added to the alarm from each sensor, and the arithmetic unit 17 that has received the alarm detects the alarm occurrence location, that is, the abnormal event occurrence section by analyzing the alarm data. To do.

  Simultaneously with this abnormal event section detection process (step S2), the monitoring camera of the section where the abnormal event is detected and the monitoring camera of the adjacent section are selected (step S3), and an alarm sound is output to the central monitoring control room (step S3). S4).

  As a result, as shown in FIG. 6, the video monitoring monitors 13a, 13b, and 13c display the video images of the monitoring cameras installed in the abnormality occurrence section and the adjacent section, and the equipment display monitor 14 The equipment data of tunnel A is displayed, and operation guidance of the equipment is displayed on the monitor 15 for guidance display.

  Next, the controller confirms the status of the abnormal event while watching the video monitoring monitors 13a, 13b, and 13c (step S5), and gives an emergency instruction to a patrol car or the like. Thereafter, the controller performs an abnormal event determination process (step S6).

  When the controller determines that the abnormal event is a fire, if the abnormal event is a fire, the fire recognition switch 43 in FIG. 2 is pressed to perform a fire certification process (step S7). If the abnormal event is an accident, 2 performs the accident recognition process (step S8) by depressing the accident switch 46 of FIG. 2, and when the abnormality report is a false report, the false report switch 42 of FIG. 2 is depressed to perform the false report process (step S9).

  In FIG. 5, the example of proceeding to the three processes of “fire”, “accident”, and “false alarm” as a result of the abnormal event determination is described. May be provided. At this time, the facility operation guidance of FIG. 4 is displayed on the monitor 15 for guidance display. In this example, “fire certification”, “accident”, “failed car”, “falling object”, “false report” are displayed. The processing step blinks and waits for manual operation input by the controller.

  When the controller depresses the fire recognition switch 43, the arithmetic unit 17 automatically executes the fire initial control process. In this embodiment, as the initial fire control process, an illumination control process (step S10), a ventilation control process (step S11), a warning display process (step S12), and a fire pump activation process (step S13) are provided. ing.

  In the lighting control process, the lighting fixtures installed in the A tunnel are controlled to be increased in number to brighten the tunnel.

  In the ventilation control, each wind fan (ventilator) 21 installed in the A tunnel and a ventilation facility such as a wind exhauster (not shown) are controlled to perform a wind direction and air volume control suitable for fire extinguishing. This wind direction air volume control may be automatically controlled by the arithmetic unit 17 taking in the measurement value of the wind direction anemometer 20 or may be manually controlled by the controller by inputting an instruction from the controller. Details of this wind direction air volume control will be described later.

  In the warning display process, for example, “A fire has occurred in the 20th section of tunnel A” is displayed on the warning display board installed in the tunnel entrance or tunnel. In the fire pump activation process, the water in the reservoir is extinguished. Inhale with a pump, and prepare to spray water from the water discharge valve at any time.

  After these initial fire control processes are performed, the controller performs a status confirmation process (step S14). If a controller who is monitoring images taken in and around the fire site finds a person evacuating from the fire site, he / she uses a loudspeaker installed in the tunnel during this status confirmation process. I do.

  After the situation confirmation process (step S14), fire extinguishing control process (step S15) such as water spray water discharge from the water discharge valve is performed, fire extinguishing control (step S16) is performed after extinguishing the fire, and normal operation processing is performed. Return. The fire recovery control is, for example, control for returning the lighting to normal lighting, performing a flue gas operation, or stopping a fire pump.

  Next, details of the above-described ventilation control, that is, the wind direction air volume control (step S11) will be described.

  When a fire breaks out in a tunnel, it is necessary to perform control according to the ventilation equipment installed along with the length and shape of the tunnel and the direction of the entrance. For this reason, according to the location of the fire occurrence point in each tunnel, the data of the wind direction and wind speed pattern that is optimal for extinguishing the fire is stored in the internal memory of the arithmetic unit 17 in advance.

  Then, when a fire actually occurs, the arithmetic unit 17 takes in the measured values of the anemometers 20 installed in various places in the tunnel, and changes the actual air flow in the tunnel to change the optimum wind direction wind speed described above. The control of the ventilation equipment is automatically executed so that the pattern, that is, the wind direction / velocity pattern that should be, is realized.

  Prior to the start of the automatic control of the ventilation control, the arithmetic unit 17 of the present embodiment displays the optimum wind direction wind speed pattern to be realized on the equipment display monitor 14 as shown in FIG.

  In the monitor display of FIG. 4, the pattern indicated by the four white arrows 91 in the ventilation facility column 90 provided at the lower left is the optimum wind direction wind speed pattern. As shown in the upper part of FIG. 4, this A tunnel is divided into 47 sections, and in this example, the 47 sections are divided into six ventilation sections 92 of N1, N2,..., N6.

  Ventilation facilities such as a plurality of jet fans 21 and a wind exhaust device (not shown) are installed in each ventilation section N1,..., N6, and the wind direction and wind speed pattern in each ventilation section is controlled by controlling each ventilation section. Then, ventilation control is executed so that the wind direction of the entire tunnel has an optimum pattern.

  In the example shown in FIG. 4, there is a blank field without an arrow between the leftmost white arrow and the second white arrow, so that the wind direction air volume at the tunnel position corresponding to this blank field is zero. Indicates that is optimal. This is because, when a fire occurs in this place, it is possible to prevent the fire from spreading by setting the wind speed at the place where the fire occurs to zero.

  When an optimal wind direction and wind speed pattern is graphically displayed with an arrow as shown in the figure, the air volume, that is, the wind speed may be expressed by the length of the arrow 91. The air volume (wind speed) may be displayed as a numerical value in the blank 93 below the arrow 91.

  In a place 94 provided corresponding to the upper part of the optimum wind direction and wind speed pattern, the wind direction and wind amount actually measured in each ventilation section is displayed. For example, the actual wind direction is indicated by a black arrow. In the illustrated example, since the actual wind direction is zero, no black arrow is displayed, and the air volume is “0.0” in all sections.

  In this way, when a fire breaks out, the desired pattern of the wind direction in the tunnel is displayed on the monitor according to the point of fire occurrence, so the controller can visually check this optimum pattern and check the ventilation control. Whether it is correct or not can be determined.

  It is necessary to change the ventilation control as appropriate according to the traffic jam situation in the tunnel at that time. For example, when smoke resistance is not installed in the tunnel, the wind speed in the vehicle traveling direction is set to 2 m / s regardless of whether there is traffic congestion. When there is, the wind speed is controlled to 0 m / s, and when there is no vehicle traffic, the wind speed is set to 2 m / s.

  Thus, when it becomes necessary to change the ventilation control manually, the controller touches the “ventilation” switch 95 on the left side of the ventilation equipment column 90 with a finger, and the “fire notch” of FIG. The switch 96 is touched with a finger. Thereby, the screen which enables the ventilation manual control for every ventilation section appears.

  In the example of FIG. 7, when the controller selects a location of the ventilation section N3 to perform manual control of the ventilation section N3 and touches the “operation notch” switch 97, the screen is switched to the screen of FIG. On this screen, for example, by touching the number “1”, the air volume in the ventilation section N3 can be controlled to 10% of the maximum air volume of the ventilation facility.

  After the fire has been extinguished, or when the state of smoke during the fire is severe, it is necessary to perform ventilation control for smoke emission. In this case, the controller touches the “smoke exhaust notch” switch 98. Thereby, the screen of FIG. 9 is displayed, and it becomes possible to designate the ventilation section where the smoke emission operation is performed. When smoke is exhausted, the desired wind direction and wind speed pattern is displayed in a graphic so that the controller can easily instruct the control of each ventilation facility with reference to this pattern.

  As described above, according to this embodiment, when performing ventilation control, the optimal wind direction and wind speed pattern that should be provided is displayed graphically on the monitor screen, so the controller can refer to this optimum wind direction and wind speed pattern. , The burden on the controller will be reduced.

  In the above-described embodiment, an example is described in which ventilation control is automatically executed so that an optimum wind direction and wind speed pattern is obtained when a fire occurs, and this ventilation control is manually changed by the controller. In the present invention, it is not always necessary to execute automatic control. When ventilation control is required, an optimal wind direction and wind speed pattern may be displayed graphically before manual control by the controller.

  As described above, the tunnel monitoring apparatus according to the present invention displays the optimum wind direction and wind speed pattern that should be optimal when performing ventilation control, so the controller can refer to this optimum wind direction and wind speed pattern. It has the effect of reducing the burden on the controller, and is useful as a tunnel monitoring device that supports the controller's judgment on ventilation in the tunnel.
