Elevator operation and maintenance monitoring method based on intelligent visual light curtain

Abstract

The invention relates to an elevator operation and maintenance monitoring method based on an intelligent visual light curtain. The method comprises the following steps that a camera and a processor are mounted in each elevator lift car, wherein the camera and the processor conduct communication transmission through a data line, and the camera is mounted in the middle above a door frame of an elevator door; each camera acquires video images in real time and transmits the images to the corresponding processor; each processor achieves full field-of-view automatic visual analysis for the area space of the corresponding elevator lift car door through an intelligent visual algorithm, and elevator faults are discovered and treated in time; and analysis and treatment results are gathered to obtain elevator operation and maintenance data which are transmitted to an elevator operation and maintenance monitoring center. Omnibearing monitoring is achieved by adoption of the elevator intelligent visual light curtain, dead zones do not exist, and the shortcomings that an infrared light curtain cannot discover small objects or is insensitive in distinguishing of the small objects are fundamentally overcome; and the monitoring range is expanded, opening and closing of the elevator door are better controlled, namely the delay door closing function is achieved, and equipment does not move along with opening and closing of the elevator door and is not prone to being intervened by external force.

Description

Technical field [0001] The invention relates to an intelligent vision technology, in particular to an elevator operation and maintenance monitoring method based on an intelligent vision light curtain. Background technique [0002] After more than 30 years of development, the elevator industry in my country has become an important construction equipment that is indispensable for the development of modern society. It has played an irreplaceable role in improving the quality of life of the people, 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, the elevator has been listed as a special equipment by the state for many years because of its function and the safety and quality of life of the people. In recent years, under the strong drive of real estate, rail transit construction, airport reconstruction and expansion, etc., my country's elevator industry has devel...
