Elevator fault diagnosis method and system

Abstract

The invention discloses an elevator fault diagnosis method. The method comprises the steps that real time data of elevator components are collected, and a theoretical temperature change curve is constructed, wherein the elevator components comprise a traction machine, a lift car portal crane, a speed governor, a buffer, a controller, a transformer and a frequency converter; actual temperature of the elevator components is collected, and real time temperature change curves are generated according to the real time temperature; the real time temperature change curves are compared with the theoretical temperature change curve, and abnormal real time temperature change curves are found; and faulted elevator components are extracted according to the abnormal real time temperature change curves. The invention further discloses an elevator fault diagnosis system. By means of the elevator fault diagnosis method and system, the theoretical temperature change curve can be constructed by collecting the real time data of the elevator components, and therefore a polling person can be better assisted in rapidly judging whether the elevator components are abnormal or not.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator fault diagnosis method and an elevator fault diagnosis system. Background technique [0002] At present, China has become the country with the largest number of elevators in the world, but the problem of elevator safety has become increasingly prominent. According to the statistics of the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, since 2003, elevator safety accidents have been ranked in the top three among the eight categories of special equipment. Among them, problems such as elevator shut down, failure to stop, abnormal operation, and inability to be repaired in time are often discussed by people living in high-rise buildings. Failure to diagnose and maintain elevator faults in time poses a great threat to passenger safety. Therefore, it is imminent to improve the level of elevator security managem...
