Railway train collision and rear-end collision preventing device based on point-to-point accurate distance measurement

Abstract

The invention discloses a railway train anti-collision and anti-rear collision device based on point-to-point precise distance measurement, which includes a self-check module, a first distance measurement module, a second distance measurement module, a first main control module, a second main control module, a second main control module, and a second main control module. An information display module, a second information display module, a first voice broadcast module, a second voice broadcast module, a first sound and light alarm module, a second sound and light alarm module, a first train brake control module, and a second train brake control module A control module, a communication conversion interface and a backup power supply, the output terminals of the backup power supply are respectively connected to the input terminals of the self-test module, the first main control module and the second main control module. The invention can prevent train collisions, prevent front and rear trains from tracking and rear-end collisions, protect key railway facilities, etc., and can provide real-time distance and sensor detection data for railway rolling stock operation tracking, navigation positioning, and intelligent transportation scheduling.

Description

technical field [0001] The invention relates to the technical field of anti-rear-collision devices, in particular to an anti-collision and anti-rear-collision device for railway trains based on point-to-point precise distance measurement. Background technique [0002] Rear-end collision refers to the behavior that the front of the rear vehicle collides with the rear of the front vehicle when vehicles traveling in the same lane are following behind. It is mainly caused by the follow-up distance being less than the minimum safety distance and the slow response of the driver or the poor performance of the braking system. For a long time, rail transit has been considered the safest way to travel. However, in recent years, the incidence of rail traffic accidents has increased, making people doubt the safety of rail transit for a while, and rail transit is different from cars. Its passenger capacity is very large, and in the event of an accident, the casualties are difficult to e...

Problems solved by technology

However, it is difficult to implement the above-mentioned technology in rail transit, mainly because the above-mentioned technology is suitable for vehicles with a large operating space and the vehicle is always in a straight-line motion state, while the operating environment in rail transit is multi-tunnel and curved roads, so the above-mentioned Technology is difficult to apply to rail transit
