Abstract

The invention provides a leakage detection method and device for a brake system, and the method comprises the steps of firstly, receiving a leakage testing instruction; then judging whether the brakesystem is in a stop state or not; when it is judged that the brake system is in the stop state, carrying out pressure adjustment on a brake cylinder; if the pressure value of the brake cylinder meetsthe leakage test requirement, judging whether the energy accumulator and the brake cylinder have leakage faults or not; and if it is judged that any one of the energy accumulator and the brake cylinder has the leakage fault, indicating that the brake system has the leakage fault. Therefore, the method for automatically and intelligently detecting the leakage of the brake system is realized.

Description

technical field [0001] The invention relates to the technical field of urban rail train control, in particular to a leakage detection method and device for a brake system. Background technique [0002] The braking system is a key subsystem in the train system. Whether the performance of the braking system is stable or not directly determines the overall safety performance of the train. [0003] At present, when checking the leakage of the brake system, it is necessary to separately detect the leakage of the accumulator pipeline and the brake pipeline in two steps, and the manual pump needs to be shaken hundreds of times to reach the specified test pressure. Very time-consuming and laborious. After the pressure stabilizes, record the pressure of the brake pipeline, and then record the brake management pressure after standing for a period of time, and calculate whether the pressure drop of the brake pipeline is within the range required by the standard. If it is not within th...
