Tunnel traffic abnormal recognition alarming device

Abstract

The invention belongs to the field of tunnel safety and discloses a tunnel traffic abnormal recognition alarming device which comprises a video image collecting module, a video image processing module, a central control module and an alarm module, wherein the video image collecting module comprises a camera, a coder, a first optical transceiver, an optical fiber, a second optical transceiver and a decoder which are successively connected; the video image processing module comprises an image pre-processing unit, a target recognition unit, a target detecting and tracking unit and a traffic parameter detection unit which are successively connected; the central control module comprises a traffic incidence detection unit and a system parameter setting unit; the output end of the decoder is connected to the input end of the image pre-processing unit, and the output end of the traffic parameter detection unit is connected to the input end of the traffic incidence detection unit; and the output end of the traffic incidence detection unit is connected to the input end of the alarm module. The device can provide passing vehicles with traffic states in the tunnel so as to avoid secondary accidents.

Description

technical field [0001] The invention belongs to the technical field of tunnel safety, and in particular relates to a tunnel traffic abnormality recognition and alarm device, which is suitable for preventing secondary accidents in expressway tunnels. Background technique [0002] With the rapid development of my country's economy, the construction of highways and highway tunnels is increasing, and the traffic safety problems of highway tunnels are becoming increasingly prominent. Tunnel safety management has increasingly become an urgent problem to be solved by traffic management departments, and the key point of tunnel safety management is traffic safety. When abnormal events (parking events, pedestrian events, retrograde events, spilled objects, congestion events) occur in the tunnel, it is extremely important to avoid secondary accidents in the tunnel and ensure the safety of passing personnel and vehicles. [0003] Due to the closed and narrow space of the tunnel and the...

Problems solved by technology

When a vicious accident occurs in a tunnel (such as dangerous goods explosion, vehicle spontaneous combustion, front and rear rear-end collisions), due to the failure of timely communication of information inside and outside the tunnel, the entrance of the tunnel did not prevent the entry of subsequent vehicles in time, resulting in continuous traffic in a short period of time. Entering the accident tunnel, on the one hand, may lead to second
