Vehicle collision emergency alarm calling device

Abstract

The invention discloses a vehicle collision emergency alarm calling device, and relates to the technical field of intelligent traffic management. The device comprises an accident alarm system, the accident alarm system comprises an alarm base station, a signal repeater, a field alarm system, a remote controller and a monitoring center. The field alarm system comprises a plasma laser transmitter, a laser diffusion device, a projector, a control box and a fog screen machine, the plasma laser transmitter and the projector are installed at the arch crown of a tunnel portal, the laser diffusion device is installed at the head of the laser transmitter, the control box and the projector are electrically connected with the monitoring center, and the fog screen machine is laid along the secondary linings of the tunnel portal. Based on a Zigbee wireless communication networking technology, a series of wireless alarm base stations and a field alarm system outside the tunnel are arranged in the tunnel, a laser virtual wall is formed at the tunnel portal by adopting a laser technology, traffic accident image information in the tunnel is displayed on the virtual wall, vehicles outside the tunnel are warned not to enter the tunnel any more, and secondary accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic management, in particular to a vehicle collision emergency alarm calling device. 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 still risk their lives without knowing that a traffic accident occurred inside the tunnel. However, the high-speed driving into the tunnel caused rear-end collisions and collisions, which caused secondary accidents. 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 occ...

AI Technical Summary

Problems solved by technology

[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

In addition, the existing technology lacks a way to effectively transmit the accident signal to every driver entering the tunnel in a timely manner. The traditional method is generally that after
