Cooperative formation train anti-collision method and device

Abstract

The embodiment of the invention discloses a cooperative formation train anti-collision method and device. The method comprises the following steps: judging whether a current train needs to be controlled for braking or not if the current train is not the first train in a formation; if the current train needs to be controlled to brake, determining whether the real-time train distance from a previousadjacent train in the same formation as the current train to the current train is greater than a preset minimum safe train distance or not; if the real-time train distance is smaller than the presetminimum safe train distance, controlling the current train to conduct electromagnetic braking; and if the real-time train distance is larger than the preset minimum safe train distance, calculating the real-time safe distance between the current train and the previous adjacent train, and when the real-time train distance is smaller than the real-time safe distance, controlling the current train toconduct braking. According to the invention, the operation capability can be effectively improved.

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
