Train braking method, train braking device, electronic equipment and storage medium

Abstract

An embodiment of the invention provides a train braking method, a train braking device, electronic equipment and a storage medium. The method comprises the steps of determining catch time of a train at each braking level according to a current velocity of the train, preset deceleration at each braking level and a target velocity curve of the train at a braking link, and determining a current braking level and braking the train according to estimated braking time of the train and the catch time of the train under each braking level. The target velocity curve comprises target deceleration of thetrain in the process of uniformly decelerating and braking from an initial position to a configuration position, and a target velocity at each moment. The estimated braking time of the train is the time required for the train to uniformly decelerate and brake from a current position to the configuration position. The train braking method, the train braking device, the electronic equipment and thestorage medium provided by the embodiment of the invention improve the train control precision, and reduce energy consumption and loss in the train braking process.

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...
