Elevator car stop detection system and detection method thereof

Abstract

The invention provides an elevator car stop detection system. The elevator car stop detection system comprises an elevator shaft, a shaft door, a camera, an elevator car, an elevator car detection circuit, a location marker, an image comparing device, a controller and an alarming machine, wherein the camera is arranged at the sidewall of the elevator shaft; the location marker is arranged at a locating surface of the elevator car and is arranged opposite to the camera. The invention also provides a detection method of the elevator car stop detection system. The image comparing device of the elevator car stop detection system provided by the invention is used for comparing an actually-shot image fed back by the camera with a location marking height in a pre-stored marking image so as to detect whether the elevator car is stopped at a correct position, and the alarming device is used for reminding a background maintenance worker to repair the elevator and reminding a passenger not to take the elevator, so potential accident hazards of the elevator are reduced.

Description

technical field [0001] The invention relates to the technical field of elevator safety management, in particular to an elevator car parking detection system and a detection method thereof. Background technique [0002] As a tool for transporting people and goods, elevators are widely used in household elevators, high-rise buildings or industrial plants. The reliability of the elevator itself plays a vital role in ensuring the safety of life and property. At present, the reliability of most elevators is very high, and redundant systems and mechanical and electrical interlocks are designed to prevent accidents. Nevertheless, under the influence of factors such as overloaded working environment, inadequate maintenance or human error, elevator accidents also occur frequently. Once an accident occurs, the result is often very serious, causing heavy casualties and property losses. In particular, when the elevator runs up and down and stops at a certain floor, the height of the st...
