Brake cylinder pressure control method, device, system and storage medium

Abstract

The embodiment of the present application provides a brake cylinder pressure control method, device, system and storage medium. The method includes: obtaining the brake cylinder pressure corresponding to each axis on the bogie of the train, the bus communication status of the train and Train running speed and determine the control mode of the brake cylinder, and control the pressure of the brake cylinder through the control mode, wherein the control mode includes independent control mode and joint control mode; according to the change of the pressure of the brake cylinder within the preset time and The current control mode adjusts the control mode of the brake cylinder. The application can select different control modes to control the pressure of the brake cylinder according to different brake cylinder pressures, bus communication status of the train and train running speed, and can adjust the control mode according to the pressure change of the brake cylinder, realizing The rapid response of the braking system to different operating conditions improves the safety of train operation.

Description

Technical field [0001] The present application relates to rail transit technology, specifically, to a brake cylinder pressure control method, device, system and storage medium. Background [0002] The braking system of subway vehicles has common braking, emergency braking, rapid braking, maintenance braking and other functions, of which commonly used braking adopts electric-air hybrid braking method, relying on electric braking and air braking to complete together, giving priority to the use of electric braking, when the electric braking is insufficient, supplementary air braking. In the case of low speed, emergency, electric brake failure, etc., the train needs to be braked entirely by air brake. [0003] In the existing brake cylinder control method of subway vehicles, the target value is first calculated according to the brake control command, and the feedback value of the brake cylinder pressure sensor is compared with the target value, and the brake cylinder is inflated, pr...
