Study on the Design of Redundant Monitoring Scheme for Parking Brake Status of High-speed EMUs
This paper systematically introduces the functional requirements,system composition and control principle of high-speed EMU parking brake design,as well as the existing parking brake status monitoring and display scheme;Aiming at the problem of accidental application of parking brake in the operation of high-speed EMUs,this paper carries out simulation analysis,puts forward an optimization scheme of redundant monitoring and control of parking brake status,and highlights the implementation scheme of parking brake status monitoring,fault diagnosis and display based on single-car parking brake redundancy monitoring and"partner car"parking brake redundancy monitoring within the unit.This scheme can effectively solve the false alarms and omissions caused by the failure of pressure sensors,parking brake monitoring unit or communication faults in the accidental application of parking brake faults.
