Elevator guide shoe pre-diagnosis method and system

Abstract

The invention discloses an elevator guide shoe pre-diagnosis method and system. The elevator guide shoe pre-diagnosis method comprises the following steps that a horizontal direction acceleration value of an elevator car is acquired through an elevator acceleration sensor, and is sent to an elevator control system; the elevator control system obtains the horizontal direction displacement value ofthe elevator car according to the received horizontal direction acceleration value; and if the horizontal displacement value is larger than a preset displacement allowable deviation value, wear abnormal information of an elevator guide shoe is output. According to the elevator guide shoe pre-diagnosis method, the use condition of the guide shoe can be detected and recorded in real time, the wear abnormal condition of the guide shoe can be found in time, and the safety performance of the whole elevator is improved.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator guide shoe pre-diagnosis method and a pre-diagnosis system. Background technique [0002] In the prior art, the sliding between the elevator guide shoes and the guide rails enables the elevator to run up and down smoothly. The rubber layer in the guide shoes and the track of the guide rails will be fatigued and worn due to the long-term sliding of the rubber layer in the guide shoes. , When the rubber layer is fatigued and worn, the elevator will emit noise during operation, causing noise pollution to the floor, and the excessively worn guide shoe rubber layer cannot be replaced in time, which also reduces the overall safety performance of the elevator. [0003] Therefore, if the guide shoe wears, it cannot be found in time, which will cause noise pollution and reduce the overall safety performance of the elevator. Contents of the invention [0004] The object of th...
