Abstract

The invention discloses an algorithm model based elevator traction steel wire rope state monitoring and early warning system and method and relates to a monitoring and early warning system and method.The algorithm model based elevator traction steel wire rope state monitoring and early warning method comprises the following steps: a, electrifying a steel wire rope with current I, and detecting the voltage value U of the steel wire rope; b, operating an elevator for one period for the first time, and calculating and recording the initial characteristic value of the steel wire rope when the elevator is in the initial state; c, when the elevator is monitored to operate, collecting and calculating the monitored characteristic value of the steel wire rope within one period and saving the monitoring characteristic value; d, according to the characteristic value of the steel wire rope, judging whether the steel wire rope has the stretching, wearing and rupturing phenomena, if yes, carrying out the step e; otherwise, repeatedly carrying out the step c; and e, sending the stretching, wearing and rupturing information of the steel wire rope and the changing position information of the steelwire rope to a terminal and a management platform. The algorithm model based elevator traction steel wire rope state monitoring and early warning system comprises a current module, a voltage detecting module, a memory module and the like. With adoption of the algorithm model based elevator traction steel wire rope state monitoring and early warning method, manpower and material resources for elevator operation can be reduced, and the risk that the entire steel wire rope fractures to cause a major accident is lowered.

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 wire rope 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 an important role. [0003] Elevator traction wire ropes play a vital role in the safe operation of elevators. Steel wire ropes are not durable elevator components, but more consumables, because they are under load for a long time, and are repeatedly bent, stretched, and rubbed. When the limit is reached, it is also a normal phenomenon that the wire rope breaks and wears. If it is not handled in time, the overall wire rope will ...
