Problems solved by technology

[0002] The inspection and maintenance of the existing elevators on the market have a fixed cycle. The company responsible for the elevator inspection and maintenance only checks the operation status of the elevator at a certain interval, such as a small inspection every year and a big inspection every three years. ,not flexible
[0003] However, using a certain fixed cycle or time to carry out safety detection on different elevators is not based on the actual working conditions of the elevators. different degrees
Therefore, due to the differences caused by the actual working conditions of different elevators, some elevators are not maintained in time, which will eventually cause safety hazards, or too frequent maintenance, wasting material and financial resources

Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Such as figure 1 Shown, a kind of method of judging elevator strain degree of the present invention, its step comprises:

[0052] Step S1: Obtain the real-time acceleration a of the elevator; determine the number of floors the elevator moves during a running process and the number of people loaded by the elevator;

[0053] Step S2: Calculate the fatigue degree of the elevator by combining the number of floors moved and the number of people loaded by the elevator:

[0054] Th=(W×num+δ)×H×n+Th 0

[0055] Th is the elevator strain value, Th 0 is the previous accumulated strain value, W is the average weight of a person, num is the number of people loaded, H is the average height of a floor, n is the number of floors the elevator moves, and δ is a coefficient that represents the loss of the elevator when it is running without l...

Abstract

The invention discloses a method for judging the elevator fatigue damage degree. The method comprises the following steps that S1, the real-time acceleration a of the elevator is obtained, and the number of moving floors of the elevator in one operation process and the number of load people of the elevator are judged; and S2, the fatigue damage degree of the elevator is calculated according to thenumber of the moving floors and the number of the load people of the elevator, wherein Th=(W*num+delta) *H*n+Th0, the Th is the elevator fatigue damage value, the Th0 is the previously accumulated fatigue damage value, the W is the average weight of one person, the num is the number of loaded persons, the H is the average height of one floor, the n is the number of the moving floors of the elevator, and the delta is a coefficient and represents the loss of the elevator during no-load operation. The method has the advantages of being simple in structure, wide in application range and high in judgment precision.

Description

technical field [0001] The invention mainly relates to the technical field of elevator control, in particular to a method for judging the strain degree of an elevator. Background technique [0002] The inspection and maintenance of the existing elevators on the market have a fixed cycle. The company responsible for the elevator inspection and maintenance only checks the operation status of the elevator at a certain interval, such as a small inspection every year and a big inspection every three years. ,not flexible. [0003] However, using a certain fixed cycle or time to carry out safety detection on different elevators is not based on the actual working conditions of the elevators. The degree is also different. Therefore, due to the differences caused by the actual working conditions of different elevators, some elevators are not maintained in time, which will eventually cause safety hazards, or too frequent maintenance, wasting material and financial resources. Conten...
