Problems solved by technology

Elevator door system failure is one of the main reasons for elevator failure. At present, elevator door maintenance is generally performed after the elevator fails or an accident, and the elevator maintenance personnel detect and analyze the cause of the failure, so as to perform maintenance. This method has a lag and cannot be repaired after the failure Early warning is issued before the occurrence, and there are certain safety hazards

Abstract

The invention relates to the technical field of elevators, in particular to an early warning method for elevator door system faults. According to the early warning method, the current of a door machine is detected to obtain the working frequency so as to obtain the working state of the door machine, and the time needed for opening or closing a door is obtained through judgment of the working state of the door machine and detection of a door opening or closing signal, and meanwhile a vibration characteristic value is obtained by detecting a vibration signal of the door; and then normalization processing and trend prediction early warning are carried out on the door opening or closing time of the door machine and the vibration characteristic value, and early warning is given out in time when a door system has the rapid degradation trend but does not reach the fault standard, so that early warning of the fault hidden danger of an elevator door system is achieved, a maintainer is reminded to take relevant countermeasures in advance, accidents caused by faults when people take an elevator are avoided, and the using safety of the elevator is greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of elevators, in particular to an early warning method for elevator door system failures. 【Background technique】 [0002] With the development of science and technology and the progress of society, elevators have become an important part of modern buildings, providing great convenience for people's lives. As a commonly used load-carrying tool in life, the safety performance of elevators is the most concerned by people. Elevator door system failure is one of the main reasons for elevator failure. At present, elevator door maintenance is generally carried out after the elevator fails or an accident, and the elevator maintenance personnel detect and analyze the cause of the failure, so as to carry out maintenance. This method has lag and cannot be repaired after the failure A warning is issued before the occurrence, and there are certain potential safety hazards. 【Content of invention】 [0003] The purpos...
