Calibration method and device for elevator lift-car position and elevator calibration system

Abstract

The invention relates to a calibration method and device for the elevator lift-car position, an elevator calibration system, computer equipment and a storage medium. The method comprises the steps that a first distance and a second distance corresponding to a current position where an elevator lift-car runs to are obtained; the first distance and the second distance are measured and obtained by distance detecting devices, and the distance detecting devices are arranged at the top and / or the bottom of the elevator lift-car and at the top and / or the bottom of a counterweight; the change tendencyof the first distance corresponding to different positions where the elevator lift-car runs to is opposite to that of the second distance; the first distance and the second distance after calibrationof the current position are obtained according to the first distance and the second distance of the current position and a distance calibration model; and the calibration is performed on the currentposition of the elevator lift-car according to the first distance and the second distance after the calibration of the current position. By means of the calibration method for the elevator lift-car position, the purpose of performing the calibration on the elevator lift-car position is realized, so that the measuring accuracy of the elevator lift-car position is improved.

Description

technical field [0001] The present application relates to the technical field of elevator calibration, in particular to an elevator car position calibration method, device, elevator calibration system, computer equipment and storage media. Background technique [0002] With the development of society, more and more buildings are built and more and more elevators are installed. Elevators have gradually become an indispensable tool in people's daily life; in order to ensure the safety of elevator operation, Accurate determination of the position of the elevator car is becoming more and more important. [0003] The position of the elevator car is measured by installing a distance detection device on the top of the elevator car and sending electromagnetic waves to the top of the elevator shaft through the distance detection device; however, if the temperature of the elevator shaft drifts, the air density or composition of the elevator shaft changes, and the surface of the distan...

Problems solved by technology

[0003] By installing a distance detection device on the top of the elevator car, the distance detection device sends electromagnetic waves to the top of the elevator shaft to measure the position of the elevator car; however, if the temperature of the elevator shaft drifts, the air density or composition of the elevator shaft changes, and the surface of the distance detection device Dust accumulation and other reasons lead to changes in the propagation direction and propagation medium of electromagnetic waves, resulting in distortion of the measured elevator car position, and cannot be calibrated by itself, resulting in low accuracy of the determined elevator car position
