Control system and method for preventing automobile secondary accidents in expressway tunnels

Abstract

The invention provides a control system and method for preventing automobile secondary accidents in expressway tunnels. The system comprises an accident detection device, a vehicle detection device, aprompting device, a prevention device, a reset detection device and a central processing unit, wherein the accident detection device is arranged in a tunnel and used for detecting whether an accidentoccurs in the tunnel or not; the prevention device is arranged in front of a tunnel entrance, the vehicle detection device is arranged in front of the prevention device and used for judging whether avehicle is to be driven into the tunnel, and the reset detection device is used for judging whether the prevention device is in an idle state or not; and the central processing unit communicates withthe accident detection device, the vehicle detection device, the prompting device, the reset detection device and the prevention device to judge whether an accident occurs in the tunnel, if yes, theprevention device and the prompting device are controlled to work, and when an accident occurs in the tunnel, the prevention device is used for forcibly lowering the speed of the vehicle to be driveninto the tunnel so that a driver can obtain the prompt information conveniently, and secondary accidents in the tunnel can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a control system and method for preventing secondary accidents of automobiles in expressway tunnels. Background technique [0002] In modern society, in order to improve the efficiency of vehicle circulation and save time, tunnels are often excavated in mountains, and vehicles pass through the tunnels, which provides great convenience for people. Tunnels are generally dug into two lanes. Compared with the road outside the tunnel, the number of lanes is reduced, resulting in a relatively large traffic flow inside the tunnel, and there is a big difference between the lighting inside the tunnel and the outside of the tunnel. The probability of traffic accidents such as collisions and scratches is higher. Because of the particularity of the tunnel, the efficiency of accident rescue in the tunnel is low. Once an accident occurs in the tunnel, the casualties and losses will be eve...

AI Technical Summary

Problems solved by technology

Due to the particularity of the tunnel, the rescue efficiency of accidents in the tunnel is low. Once an accident occurs in the tunnel, the casualties and losses will be even greater

At the same time, because external vehicles often cannot know the tunnel road condition information at the first time, it is easy to make the car behind hit the accident vehicle and cause a secondary accident, which brings greater economic losses to people.

In the prior art, by setting a display screen or a voice prompter at the tunnel entrance, passing vehicles are notified of the road conditions in the tunnel, but this prompt is not targeted, and because the speed of the vehicle is too fast on the expressway, the driver often does not have enough The time to capture the prompt message
