REMOTE SELF-DIAGNOSIS METHOD OF BRAKING PERFORMANCE OF ELEVATOR

摘要

A remote self-diagnosis method of braking performance of an elevator. The method comprises: controlling the elevator to run at a constant speed after information of a reference position between a distance measurement sensing module and a fixed reference point and a proportionality coefficient between a rotating position of a traction motor encoder and a vertical movement distance of the elevator are calculated; braking the elevator when the elevator reaches a rated speed and is close to a stopping preset position; collecting a real-time distance between the distance measurement sensing module and the fixed reference point and a real-time rotating position of the traction motor encoder in the braking process of the elevator; and then calculating braking performance parameters of the elevator, and further, performing contrast judgment on the obtained braking performance parameters and a preset safety range, so as to perform the self-diagnosis on the braking performance of the elevator. In the method, various braking performance parameters of the elevator can be obtained by means of automatic tests and the remote self-diagnosis can be performed on the braking performance of the elevator without manual measurement, and the remote self-diagnosis is highly accurate and rapid.
