Train braking method, device, electronic equipment and storage medium

Abstract

Embodiments of the present invention provide a train braking method, device, electronic equipment, and storage medium, wherein the method includes: according to the current speed of the train and the preset deceleration at each braking level, and the braking speed of the train under the braking link The target speed curve determines the catching up time of the train at each braking level; according to the estimated braking time of the train and the catching up time of the train at each braking level, determine the current braking level and control the train The target speed curve includes the target deceleration and the target speed at each moment during the process of uniform deceleration and braking of the train from the initial position to the configured position. The time required to configure the location described above. The method, device, electronic equipment and storage medium provided by the embodiments of the present invention improve the precision of vehicle control and reduce the energy consumption loss during the braking process of the train.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a train braking method, device, electronic equipment and storage medium. Background technique [0002] With the advancement of urbanization, urban rail transit technology has made continuous development and progress. The automatic train operation system (Automatic Train Operation, ATO) car control technology has also been paid more and more attention by people. The ATO system controls the traction, coasting and braking of the train under the limited conditions such as road speed limit, so as to realize the functions of efficient and reasonable automatic driving and section operation of the train. The quality of the ATO control strategy will directly affect the stable and efficient operation of the train. [0003] In the prior art, when the ATO system controls the train to brake, it usually uses multiple braking levels for braking. Frequent switching between braking levels results in...
