摘      要：Purpose–The brake controller is a key component of the locomotive brake *** is essential to study its ***/methodology/approach–This paper summarizes and analyzes typical faults of the brake controller,and proposes four categories of faults:position sensor faults,microswitch faults,mechanical faults and communication *** and methods for improving the safety of the brake controller are also ***–In this paper,a self-judgment and self-learning dynamic calibration method is proposed,which integrates the linear error of the sensor and the manufacturing and assembly errors of the brake controller to solve the output *** paper also proposes a logic for diagnosing and handling microswitch *** are proposed for other faults of brake ***/value–The methods proposed in this paper can greatly improve the usability of the brake controller and reduce the failure rate.
