Collision avoidance method and device for coordinated trains

Abstract

The embodiment of the present invention discloses a method and device for avoiding collision of trains in coordinated formation. The method for avoiding collision of trains in coordinated formation includes: if the current train is not the first train in the formation, judging whether it is necessary to control the current train for braking ; If it is necessary to control the current train to brake, it is determined whether the previous adjacent train in the same formation as the current train has a real-time vehicle distance to the current train greater than the preset minimum safety distance; if the If the real-time vehicle distance is less than the preset minimum safe vehicle distance, then control the current train to perform electromagnetic braking; if the real-time vehicle distance is greater than the preset minimum safe vehicle distance, then calculate the distance between the current train and the The real-time safety distance of the previous adjacent train, and when the real-time vehicle distance is less than the real-time safety distance, control the current train to brake. The operation capability can be effectively improved by adopting the invention.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for avoiding collisions of coordinated trains. Background technique [0002] With the continuous development of rail transit technology, in order to improve operational capabilities, more and more operators have adopted the operation scheme of coordinated formation, and the trains in the formation can track back and forth. In order to ensure operational capability, how to avoid collisions between trains and reduce the occurrence of train rear-end collision accidents is also particularly important. [0003] At present, the urban rail transit control system usually uses ATP (Automatic Train Protection, automatic train protection system) to prevent trains in formation from colliding. Specifically, ATP can calculate the upper speed limit and speed limit line of the current train according to the current train position, the line marking information of the cur...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when ATP calculates the upper limit of speed, the upper limit of speed and the speed limit line are determined by the line markers, but the markers of the route cannot accurately represent the real position of the previous train, so that the calculated upper limit of speed and the speed limit line It is not optimal, so that the distance between trains in the formation is usually large, and thus cannot better improve the operating capacity
