Elevator traction wheel state monitoring and early warning system and method based on algorithm model

Abstract

The invention discloses an elevator traction wheel state monitoring and early warning system and method based on an algorithm model, and relates to a monitoring and early warning system and method. The system comprises a deflection detection system, an abrasion detection system, an environment information acquisition system, an information alarm system and a control system; the method comprises the steps of traction wheel deflection monitoring and early warning, and traction sheave abrasion, internal cracks and positioning monitoring and early warning; and the traction wheel deflection monitoring and early warning comprises the steps of A1, starting a laser transceiver; A2, calculating and recording an initial distance value between one end face of a traction wheel and the laser transceiver in an initial period; A3, collecting whole-process monitoring data in an operation period, and calculating a monitoring distance value from one end face of the traction wheel to the laser transceiver; and A4, judging whether the traction wheel deviates or not according to the monitoring distance value between the traction wheel and the laser transceiver. According to the system and the method, real-time accurate detection and early warning can be carried out on deflection, abrasion, cracks and positioning of the traction wheel, the safety performance of an elevator can be improved, and application and popularization are easy.

Description

technical field [0001] The invention relates to a monitoring and early warning system and method, in particular to an algorithm model-based elevator traction sheave state monitoring and early warning system and method. Background technique [0002] In modern society, the use of elevators is very extensive. It can be said that it is inseparable from people's daily life. It has become a ubiquitous device for transporting people and goods in multi-storey buildings. Frequent stops and continuous operation, the safety performance of the elevator plays a very important role. [0003] The existing elevator car and the counterweight device are usually connected by a wire rope, and the wire rope is driven to move through the traction sheave to realize the movement of the elevator car in the shaft. On the wheel groove, as the service life of the traction sheave increases, the wheel groove of the traction wheel will wear out. As the amount of wear increases, the shape of the wheel gro...
