A method for judging the degree of elevator strain

Abstract

The invention discloses a method for judging the degree of elevator strain. The steps include: step S1: obtaining the real-time acceleration a of the elevator; judging the number of floors moved by the elevator in a running process and the number of people loaded by the elevator; step S2: combining the moving The number of floors and the number of people loaded by the elevator are used to calculate the degree of fatigue of the elevator: Th=(W×num+δ)×H×n+Th 0 ; where 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 moved by the elevator, and δ is a coefficient that represents the loss when the elevator runs without load . The invention has the advantages of simple rationale, wide application range and high judgment accuracy.

Description

technical field [0001] The invention mainly relates to the technical field of elevator control, in particular to a method for judging the degree of elevator strain. Background technique [0002] The inspection and maintenance of the existing elevators on the market are all on a fixed cycle. The company responsible for elevator inspection and maintenance only checks the operation status of the elevator at certain intervals, such as a small inspection every year and a major inspection every three years, and the inspection cycle is rigid. ,not flexible. [0003] However, the method of using a certain fixed cycle or time to conduct safety inspections on different elevators is not based on the actual working conditions of the elevators. This is because the loads and running distances of different elevators are different in different time periods, so that the fatigue of the elevators is different. The degree is also different. Therefore, due to the differences caused by the actu...

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
