Description

Technical Field

[0001] The utility model relates to a field, and in particular to a faulty vehicle warning system in a tunnel. Background Art

[0002] Highway tunnels are characterized by large traffic volume, a high proportion of trucks, and low visibility. After a vehicle breaks down in a tunnel, due to the limited behavioral ability or poor safety awareness of the driver and passengers, it is sometimes impossible to place a triangular warning sign upstream of the broken-down vehicle. If the upstream vehicle does not receive the warning information and drives at a normal speed, a rear-end collision is very likely to occur, causing casualties to the driver and passengers. Vehicle rear-end collisions may also cause accidents such as fires and leakage of hazardous materials, resulting in greater casualties and property losses. In addition, since vehicle breakdown events in tunnels are random in space and time, tunnel managers cannot get to the scene to intervene immediately after they occur. Therefore, when a breakdown accident occurs in a tunnel, a system is needed to set up a warning system for subsequent vehicles in the tunnel to effectively prevent rear-end collisions.

[0003] The patent with patent number 202220119296.9 discloses a safety warning device after a tunnel traffic accident, including a laser radar, a processor, a controller, an LED light, a wireless signal transmitter, and a traffic control center. The laser radar, warning light, processor, and controller are arranged along the inner wall of the tunnel. When traffic safety is in operation, the LED lights can be used as lighting and sight induction devices in the tunnel. When an accident occurs, the laser radar detects that the speed of the accident vehicle is 0, and the processor determines that the traffic is in an abnormal state. The controller adjusts the surrounding LED lights to start the red rotating flashing warning function, so as to remind subsequent vehicles to pay attention to avoid and reduce the occurrence of secondary accidents. At the same time, the controller feeds back the tunnel accident information to the traffic control center, coordinates the relevant departments to deal with the accident as soon as possible, and starts the LED lighting function after the accident is handled.

[0004] However, this patented technology provides a warning by activating the red rotating flashing warning function of the LED lights within 200 meters around the accident vehicle, and the warning range is limited; and its LED lights are set on the side of the tunnel, making it difficult for drivers and passengers to observe.
