Elevator guide rail support interval measuring method, device and equipment and storage medium

Abstract

The invention discloses an elevator guide rail support interval measuring method, device and equipment and a storage medium. The method comprises the following steps: S1, mounting an infrared laser distance measuring device and an acceleration measuring device; S2, enabling the infrared laser distance measuring device to obtain distance data; S3, taking a data stream T according to the time sequence of obtaining the data; S4, sorting the T from small to large to obtain S={S1, S2, S3,..., Sn}; S5, dividing the obtained distance data stream into support position data and hoistway wall position data; S6, taking the mean value of the first 0.5%-1% of data items to obtain a formula defined in the specification; S7, taking K={S0.31n, S0.32n, S0.33n,..., S0.80n}, and calculating a formula definedin the specification; S8, setting Yi belongs to Y= {1,-1}; and if the absolute value of (Si-X1) is smaller than the absolute value of (Si-X2), Yi is equal to 1, otherwise, Yi is equal to -1; S9, averaging Si of which Yi is equal to 1 to obtain a new feature mean value X1; and solving a mean value of Si of which Yi is equal to -1 to obtain a new feature mean value X2; and S10, repeating the stepsS8-S9 until the Yi values corresponding to the Si are not changed for two consecutive times, and obtaining final classification feature values X1 and X2. The elevator guide rail support and the edge position of the elevator guide rail support can be obtained by measuring the distance from the top of an elevator car to the guide rail support and the shaft wall in real time.

Description

technical field [0001] The invention is applied to the field of elevator installation and inspection and detection, and is specifically a method, device, equipment and storage medium for measuring the distance between elevator guide rail brackets. Background technique [0002] The elevator guide rail bracket, as one of the important components of the elevator guide system, is used to support and fix the guide rail, which is directly related to the safety and comfort of the elevator. GB 7588—2003 "Code for Manufacture and Installation of Elevators" provides strict control on the permissible disturbance of the "T" guide rail of the elevator. In addition to the material of the guide rail, the deformation of the guide rail is directly related to the distance between the brackets. Elevator Inspection Regulations TSG T7001—2009 "Elevator Supervision Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" has clear regulations on the spacing of the brackets:...

Problems solved by technology

The measurement of the bracket spacing has always been the focus of the elevator supervision and inspection process. The traditional inspection method is to manually measure one by one on the top of the car, which is time-consuming and laborious, and is likely to cause safety accidents.

Domestic elevator guide rail bracket spacing automatic measuring instruments mostly use proximity switches or similar switches as the solution to detect the bracket position, and the detection technology and data processing Automation&Instrumentation 2019, 34(12) The installation of touch sensors is bound to be subject to on-site equipment environment, the inspection efficiency is low, and the versatility is not strong
