Method for realizing intelligent vision system for synchronous detection of elevator brake spring

Abstract

The invention relates to a method for realizing an intelligent vision system for synchronous detection of an elevator brake spring, which comprises the following steps: when an elevator inspector periodically detects the brake force of an elevator, an installation detection camera is installed beside an elevator brake device in an elevator machine room, and a camera video signal is transmitted toa computer through a cable; the computer is connected with an elevator brake device control panel through an I / O interface, and an elevator brake signal is obtained; the computer receives informationof an state image of the elevator brake spring, which is automatically and continuously captured by the camera; the action states of the two springs of the left and right brakes of the elevator are detected through an image processing and mode recognizing algorithm in the computer; and the synchronous situation of the elevator brake spring is automatically detected and calculated. The method in the invention realizes accurate detection on reduction of the brake force of the elevator due to incapability of synchronization of the left and right springs of the elevator brake, can find the fatal elevator safety problem of insufficient brake force of the brake in advance and finds causes of problems so as to solve the potential safety hazard of the elevator quickly and accurately.

Description

technical field [0001] The invention relates to a visual detection technology for elevator brake springs, in particular to a method for realizing an intelligent vision system for synchronous detection of elevator brake springs. Background technique [0002] After more than 30 years of development, my country's elevator industry has become an indispensable and important construction equipment for the development of modern society. It has played an irreplaceable role in improving people's quality of life, improving the quality of life, and realizing the national policy of "energy saving and land saving" in my country's construction industry. supporting role. At the same time, elevators are closely related to the safety and quality of life of the general public because of their functions, and have been listed as special equipment by the state for many years. In recent years, under the strong drive of real estate, rail transit construction, airport reconstruction and expansion, ...
