An Elevator Weighing Method Based on Capacitance Change

Abstract

The invention relates to an elevator weighing method based on the change of capacitance value, comprising: obtaining the training set data of the elevator through testing; performing network training through the obtained training set data; It is stored in the single-chip microcomputer; the quality of the passengers and objects currently carried by the elevator is obtained by reading the voltage at both ends of the capacitor; it is judged whether the elevator is overloaded, and if it is overloaded, an overload signal is sent. According to the change of capacitance in the self-designed bottom structure of the elevator, this solution can calculate the quality of the passengers or objects carried by the elevator through the neural network, which can solve the problem of accurate weighing of the elevator to a certain extent.

Description

technical field [0001] The invention relates to the field of elevator weighing, and more specifically, relates to an elevator weighing method based on capacitance value changes. Background technique [0002] How to improve the various functions of the elevator under the premise of ensuring the safe operation of the elevator has become an urgent problem to be solved. [0003] In the past, the weighing of elevators mostly used the method of judging whether there was an overweight phenomenon based on the deformation of the bottom. It was impossible to accurately obtain the quality of passengers or objects carried by the elevator. The passengers could not know the quality of the elevator at this time, so they could not accurately judge the weight At the same time, the traditional weighing method can only roughly judge the quality of the elevator, and there are certain safety hazards. [0004] Due to the existence of many restrictive factors in the actual operation of the elevat...

Problems solved by technology

[0003] In the past, the weighing of elevators mostly used the method of judging whether there was an overweight phenomenon based on the deformation of the bottom. It was impossible to accurately obtain the quality of passengers or objects carried by the elevator. The passengers could not know the quality of the elevator at this time, so they could not accurately judge the weight At the same time, the traditional weighing method can only roughly judge the quality of the elevator, and there are certain safety hazards

[0004] Due to the existence of many restrictive factors in the actual operation of the elevator, the measured data often cannot accurately fit the linear relationship or the multi-function relationship
