[0022] like Figure 1 As shown, the present application relates to a tunnel gas monitoring and alarm system, comprising: at least one gas detector, arranged in the tunnel; a central processor, which receives the detection signal of the gas detector; a communication device, connected to the central processor, which sends the detection signal; and a display device, which displays the position of the gas detector.

[0023] When the gas detector detects a gas leak, it sends the detection signal to the central processor. The central processor then sends the detection signal to the backstage monitoring personnel and displays the location of the leak on the display. The monitoring personnel then send maintenance personnel to check and repair it.

[0024] In one embodiment of the present application, the tunnel gas monitoring and alarm system further includes: an exhaust duct; and at least one exhaust fan, the exhaust fans are arranged one by one at the gas detector; when the central processor receives the detection signal detected by the gas detector, it controls the exhaust fan corresponding to the gas detector to turn on, sucking the gas into the exhaust duct, and then discharging the gas from the exhaust duct to the outside of the tunnel. In this embodiment, before the maintenance personnel arrive at the leakage site, the leaked gas can be temporarily discharged to the outside of the tunnel through the exhaust fan.

[0025] In one embodiment of the present application, the tunnel gas monitoring and alarm system further includes: a temperature detection sensor connected to the central processor. After the temperature detection sensor sends the tunnel temperature to the central processor, the central processor calculates the possibility of fire according to the temperature.

After the humidity detection sensor sends the tunnel temperature to the central processor, the central processor calculates the possibility of fire according to the humidity.

[0027] In one embodiment of the present application, the tunnel gas monitoring and alarm system further includes: at least one isolation door, which is arranged between two adjacent gas detectors. When the central processor receives the detection signal detected by the gas detector, it controls the isolation door adjacent to the gas detector to close.

[0028] In one embodiment of the present application, the isolation door can be folded into a groove at the top of the tunnel; the isolation board is provided with a temporary door for personnel to escape, and the groove is provided with a baffle for closing the isolation door in the groove.

[0029] In one embodiment of the present application, the isolation door is a hollow structure, and the isolation door is made of soft fireproof material, and the isolation door can be filled with inert gas. When a fire occurs, the isolation door is opened and the inert gas is filled into the isolation door. In this way, if the isolation door is burned through, the inert gas can extinguish the fire. In addition, since the isolation door is made of soft fireproof material, when the gas is filled, the isolation door can expand and adapt to the cross-sectional shape of the tunnel without leaving any gaps. So that the fire can be completely sealed.

[0030] In one embodiment of the present application, the tunnel gas monitoring alarm system further includes: a driving device connected to the baffle, and the central processor controls the baffle to open so that the isolation door extends downward and opens under the action of gravity.

[0031] In one embodiment of the present application, the tunnel gas monitoring and alarm system further includes: an air pump connected to the central control structure of the isolation door, and the air pump inflates the central control structure.

[0032] In one embodiment of the present application, the tunnel gas monitoring and alarm system further includes: a mobile terminal, and the communication device sends the detection signal to the mobile terminal.

[0033] The tunnel gas monitoring and alarm system of the present application can monitor the fire situation in the tunnel in real time and isolate the fire when it occurs, effectively reducing the losses caused by the fire.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
