Highway tunnel traffic safety accident display alarm device

Abstract

The invention discloses a highway tunnel traffic safety accident display alarm device that is composed of a plasma laser emitter, a laser diffusion device, a projector, a control box and a fog screenmachine. When a traffic safety accident occurs in the tunnel, a worker sends the type and image information of the traffic safety accident to the control box and the projector through a tunnel centralcontrol management system. The control box controls the plasma laser emitter to emit laser beams; the laser beam forms a virtual wall at the tunnel portal under the action of the laser diffusion device; a driver is prompted that a traffic accident occurs in the tunnel; the control box controls the fog screen machine to spray fog to the hole; the projector projects traffic accident image information in the tunnel sent by the tunnel central control management system to fog sprayed by the fog screen machine, the traffic accident image information in the tunnel is presented on the fog, and Chinese characters of accident types are displayed on images so as to remind coming vehicle drivers of the types of traffic safety accidents in the tunnel.

Description

technical field [0001] The invention relates to the field of fire monitoring, in particular to a display and alarm device for road tunnel traffic safety accidents. Background technique [0002] The emergence of tunnels has greatly reduced the operating mileage between two points, and has also improved the operational efficiency of highways. The tunnel is a relatively closed site, and it is also a place where traffic safety accidents frequently occur. Once a traffic accident occurs, it is difficult for drivers outside the tunnel to know. Often, vehicles outside the tunnel will rush to the tunnel without knowing that a traffic accident has occurred inside the tunnel. Driving into the hole, causing a secondary accident. Especially for highway tunnels, once a high-speed vehicle enters a tunnel where a traffic safety accident occurs, it is difficult to brake quickly, and chain collisions are likely to occur.

The tunnel is a relatively closed site, and it is also a place where traffic safety accidents frequently occur. Once a traffic accident occurs, it is difficult for drivers outside the tunnel to know. Often, vehicles outside the tunnel will rush to the tunnel without knowing that a traffic accident has occurred inside the tunnel. Driving into the hole, causing a secondary accident

Especially for highway tunnels, once a high-speed vehicle enters a tunnel where a traffic safety accident occurs, it is difficult to brake quickly, and chain collisions are likely to occur

[0003] In the prior art, variable information boards are installed outside the tunnel and above the tunnel. The real area of ​​these variable information boards is small, and the installation height is high, which is not easy to attract the driver's attention, especially in low visibility, It is more difficult for the driver to recognize the information on the variable information board in the case of a short line of sight
