Embodiment 1

[0031] Such as figure 1 As shown, an anti-collision method for rail vehicles includes the following steps:

[0032] Get the current position of the rail vehicle;

[0033] Obtain the current speed of the rail vehicle, and calculate the braking distance S1 of the rail vehicle according to the braking deceleration a and the current speed v of the rail vehicle;

[0034] According to the current position of the rail vehicle and the braking distance S1 of the rail vehicle, control the road signal lights in the range of 0 to 5 meters on both sides of the rail vehicle and 0 to S1 in front to turn on red; 5 to 10 meters on both sides of the rail vehicle And the road signal lights within the range of S1~2 times S1 ahead will be yellow;

[0035] When detecting other vehicles in the dangerous area, sound the horn to warn; when detecting other vehicles in the high-risk area, take photos for evidence and brake urgently.

Embodiment 2

[0037] Such as figure 2 As shown, an anti-collision device for rail vehicles includes:

[0038] Pavement signal lights, the pavement signal lights are laid along the driving route of the rail vehicle, and the paving range is an area within ten meters of the inner side of the track and the outer side of the track, the road signal lights include a yellow LED light group and a red LED light group;

[0039] The positioning module is used to obtain the current position of the rail vehicle;

[0040] The calculation module is used to calculate the braking distance S1 of the rail vehicle according to the braking deceleration a and the current speed v of the rail vehicle;

[0041] The control module is used to control the road signal lights in the range of 0 to 5 meters on both sides of the rail vehicle and 0 to S1 in front to turn on red according to the current position of the rail vehicle and the braking distance S1 of the rail vehicle; The road signal lights within the range of 5~10 meter...

Abstract

The invention discloses an anti-collision method and device for a rail vehicle. The anti-collision method comprises the following steps of 1, calculating a braking distance S1 of the rail vehicle according to a braking deceleration a and a current speed v of the rail vehicle; and 2, according to the current position of the rail vehicle, turning on a road signal lamp within a safe distance S2 fromthe current position of the rail vehicle to the front, wherein S1 is less than or equal to S2, S2 is less than or equal to 2 * S1. Due to the adoption of the technical scheme, compared with the priorart, the anti-collision method and device determines the dangerous area according to the braking deceleration, the current speed and the current position of the rail vehicle, and lights the dangerousarea through road signal lamps with different colors to warn other traffic vehicles not to enter the dangerous area, thus avoiding collision risks between the rail vehicle and other traffic vehicles;and the dangerous area is further divided into high risk areas (high risk areas) and dangerous areas (dangerous areas), early warning of different levels of danger is provided for drivers of other traffic vehicles.

Description

Technical field [0001] The present invention relates to the technical field of rail transit, in particular to a method and device for preventing collisions of rail vehicles. Background technique [0002] In the prior art, some rail vehicles need to occupy urban roads during operation, and there are certain safety hazards with other traffic vehicles, such as collisions with other vehicles, scratches, etc. Due to the large size and weight of the tram, the momentum entrained in the driving process is large, and when it collides with other vehicles, it will often cause huge traffic accidents. There are many emergent factors in the process of traffic participation, and accidents cannot be completely avoided simply by means of management center scheduling and driver emergency operations. Therefore, it is urgent to develop a method and device for preventing collisions of rail vehicles. Summary of the invention [0003] In order to solve the problem of the collision risk between the exis...
