BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a warning device for a tunnel according to the present invention. A is a two-lane highway or general road, and a traveling vehicle enters the tunnel B from the right with respect to the tunnel B. Although not shown in the tunnel B, television cameras are installed at predetermined intervals, and images from the television cameras are monitored by monitors at a road management office 24 hours a day. Then, in response to the occurrence of an accident or a fire, a drive signal is transmitted to a smoke emitting device and an alarm display panel of the present invention described later.

1 is a smoke generating device shown in detail in FIG.
A case 11 having an opening 11a formed in one side of the side surface and having a smoke accommodating space 11b therein;
When a driving signal from the road management office is input, the heater in the smoke generator 12 is energized by heating a liquid such as glycogen fixed to the lower portion of the heater to generate white smoke. And a control circuit 13. Reference numeral 14 denotes a red light emitting device which is attached to the outside of the case 11 near the opening 11a and irradiates red light to smoke emitted from the opening 11a.

Reference numeral 2 denotes a full-color alarm display panel provided with an LED on a display surface provided in front of the entrance to the tunnel B, and a memory contained therein stores a vehicle fire occurring in the actual tunnel. And video information of the accident. Reference numeral 3 denotes a camera fixed to the beam column of the alarm display panel 2, and a monitoring area A1, which is a shooting range of the camera 3, is indicated by hatching.

Next, a description will be given of the operation based on the above-described configuration. A management clerk who looks at the monitor of the road management office recognizes that a vehicle fire or an accident has occurred in the tunnel B, and When a drive signal is output to the smoke generating device 1 and the alarm display plate 2 installed at the wellhead of B, the control circuit 13 of the smoke generating device 1 energizes a heater (not shown). Is displayed, an accident image stored in advance is selected, and alternate display of characters and moving images is performed on the display surface.

On the other hand, the heater of the smoke generating device 1 is energized, and after a predetermined time elapses, the glycogen liquid is vaporized and white smoke is generated by a fan (not shown) built in the smoke generator 12 and stored in the smoke storage space 11b. At the same time, a fan (not shown) provided on the side of the smoke accommodating space 11b is driven, and white smoke filling the smoke accommodating space 11b is opened.
It is discharged at high speed via 1a.

Therefore, this white smoke seems to be discharged from the wellhead due to the accident in tunnel B,
The driver of the traveling vehicle who suspects the occurrence of the accident by seeing the word “occurrence in the tunnel” and the accident image on the alarm display board 2 must be aware that the accident has occurred due to white smoke from the vicinity of the tunnel entrance. Will be stopped.

Further, when the television camera 3 detects a vehicle passing at high speed in the monitoring area A1 where the television camera 3 is taking a picture despite the warning with the image and the smoke, the smoke of the smoke is generated. The amount of generated heat of the heater and the rotation of the fan in the smoke generating apparatus 1 in a state where the amount of generated smoke is suppressed can be accelerated to generate a large amount of white smoke, thereby further calling attention.

As described above, when there is no vehicle passing through the monitoring area A1 at high speed, the amount of smoke generated by the smoke generating device 1 which cannot discharge white smoke for a long time is suppressed, and the vehicle passes through the monitoring area A1 at high speed. When a car entering the area needs to be alerted more strongly, it generates more white smoke to reduce the consumption of the glycogen solution, which is a smoke-generating material, and perform effective smoke generation. It becomes possible.

Further, when the white smoke of the smoke generating device 1 is generated, the red light emitter 14 that emits red light is turned on, so that the white smoke becomes red and looks like a flame. Realism can be expressed, the driver can be strongly appealed, and aggressive entry into the tunnel B can be prevented.

In the above-mentioned embodiment, as a driving signal of the smoke generating device 1 and the alarm display panel 2, the road management office monitors and monitors the driving signal in response to an accident or a vehicle fire as a result of monitoring. Although the description has been given of the case where the signal is transmitted to drive the smoke generating device 1 and the alarm display panel 2, a fire detector and a vehicle detector for detecting that an accident has occurred and the vehicle has stopped in the tunnel and the accident Since a push button type notification device operated by the driver etc. in the event of emergency such as occurrence is installed, in response to detection means such as fire detectors and vehicle detectors,
Alternatively, the smoke generating device 1 and the alarm display panel 2 may be driven by a driving signal output in response to the push button type notification device.

The smoke generator 1 has a plurality of smoke generators 12.
It is possible to cope with long-term continuous smoke generation by accommodating and alternately using, and furthermore, in order to shorten the smoke start time, the heater of the smoke generator 12 may be constantly supplied with power and may be in a standby state. .

Further, the smoke generating device 1 is not limited to the one using the glycogen in the above embodiment, and for example, a smoke tube or the like can be considered. Further, the image displayed on the alarm display board 2 is to display an image of a fire when the accident in the tunnel B is a vehicle fire, and to display an image of an accident other than the fire in the case of a rear-end collision or the like. Is desirable.

Furthermore, although the alarm display panel in the above-described embodiment has been described as a full-color display panel, the alarm display panel is not limited to the full-color display panel.

[0024]

According to the present invention, as described above, white smoke is generated in the event of an accident or fire by the smoke generating device installed near the tunnel entrance, so that the smoke is generated in the tunnel within the driver's field of view. It is possible to intuitively recognize that an abnormality has occurred.

[0025] Further, since an image of an accident or the like is displayed as a moving image on the smoke emitting device and an alarm display plate installed in front of the smoke emitting device, the driver can be further alerted. The next disaster can be prevented.

Further, when a camera is installed in front of the warning display board, and when the camera recklessly detects a vehicle heading for the tunnel, the amount of smoke emitted from the smoke generating device is increased, and the driver is more at risk of danger. By illuminating the white smoke from the smoke emitting device with red light from the red light emitter, it is possible to express a more realistic feeling and appeal to the driver strongly, This has the effect that it is possible to prevent forcible entry into the vehicle.
