Embodiment 1

[0057] Most emergencies in the tunnel are caused by abnormal vehicles. There must be relevant signs when abnormal vehicles drive outside the tunnel. There must be signs of abnormal driving outside the cave if the incident occurs.

[0058] The highway tunnel driving safety risk identification and prevention and control system provided in this embodiment has a system hardware topology as shown in figure 1 As shown, the system layout diagram is shown in Figure 6, which specifically includes:

[0059] The entrance ring network switch is used for data exchange and transmission of various parts in the system. The selection of the entrance ring network switch is not limited, and it can be implemented in a way that can be realized in the prior art, for example, Mosa EDS-510A-3SFP-T can be selected.

[0060] The radar speedometer is installed outside the tunnel entrance, preferably 3 times the parking sight distance from the tunnel entrance. It is connected with the local industrial co...

Embodiment 2

[0092] When the abnormal vehicle is actually driving, it may happen that the driver does not notice the warning information on the information board, or sees the water screen projection with the warning information but does not react. The driver continues to drive into the tunnel, which will A safety hazard is formed in the tunnel.

[0093] In order to solve the above technical problems, further optimization is carried out on the basis of embodiment 1, and the following technical solutions are adopted:

[0094]Such as Figure 4 , Figure 5 As shown, the highway tunnel traffic safety risk identification and prevention system also includes:

[0095] The bayonet camera, the bayonet camera is set at the exit of the tunnel, and is connected with the local industrial control electromechanical through the exit ring network switch. In a specific embodiment, such as Figure 5 As shown, a door frame 2 is installed at the exit of the tunnel, and a bayonet camera is installed on the d...

Embodiment 3

[0102] The technical solution of this embodiment is basically the same as that of Embodiment 1, the difference is that the visible light and infrared all-in-one machine installed in the middle and side of the door frame 1 at the entrance of the tunnel is replaced by a bayonet camera and an infrared thermal imager; a bayonet camera, The infrared thermal imager is respectively connected with the local industrial control electromechanical through the export ring network switch.

[0103] The bayonet camera is used to take the driving video of the vehicle, and the infrared thermal imager is used for the infrared thermal imaging image of the vehicle. Using the bayonet camera and infrared thermal imager respectively, you can obtain clearer vehicle driving video and vehicle infrared thermal imaging images, so that the local industrial computer can analyze the abnormal state of the vehicle more accurately.

Abstract

The invention provides a highway tunnel traffic safety risk identification and prevention and control system which comprises an entrance looped network switch, a radar velocimeter arranged outside a tunnel entrance, a visible light and infrared all-in-one machine, an information board and a flexible water curtain blocking subsystem arranged at the tunnel entrance. The local industrial personal computer identifies whether the vehicle is in an abnormal state or not according to the vehicle speed, the vehicle driving video and the vehicle infrared thermal imaging image; if abnormity exists, the local industrial personal computer pushes alarm information to the information board and the flexible water curtain blocking subsystem, and meanwhile, the vehicle license plate number and the alarm information are pushed to the cloud platform through the wireless routing gateway; radar speed measurement, video recognition and thermal imaging technologies are integrated, the technical problem that operation safety accidents in a tunnel hole cannot be reduced or prevented from risk sources at present can be solved, abnormal vehicles with potential risks can be monitored, early warned and blocked, and traffic accidents in the highway tunnel can be reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel operation safety, in particular to a method and system for risk identification, prevention and control of road tunnel driving safety. Background technique [0002] As of the end of 2020, my country has a total of 21,316 highway tunnels with a length of 21.9993 million meters. It is the country with the largest number of tunnels and the longest mileage in the world. As a key structure and throat project of highway infrastructure, the safety of tunnel operation is directly related to the smoothness and efficiency of the road network, and has an important impact on the sustainable and healthy development of the economy and the safety of people's lives and property. Due to the closed structure of the tunnel, poor visibility, small space, and difficult rescue, once an accident occurs, the traffic capacity and driving safety of the entire tunnel section will be affected, posing a great threat to people's...
