Problems solved by technology

[0004] 1) Equipment maintenance is basically a planned maintenance, and highly dependent on people, the phenomenon of redundant maintenance is serious;
[0005] 2) The current monitoring system can only monitor the operating status of the elevator door, which is passive monitoring and lacks early warning and health status assessment;
[0006] 3) Subsequent maintenance, resulting in unexpected downtime and high maintenance time and cost

Embodiment Construction

[0057] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0058] The embodiment of the present invention provides a method and device for health maintenance of the elevator door system. By collecting the current data of the specific working condition of the elevator door in real time, the health status of the elevator door is evaluated by using the pre-established health evaluation model, and the evaluation result is obtained. , so as to realize the active and online monitoring of the health status of the elevator door system.

[0059] Considering that a door opening or closing process involves many complex operations, when building the health assessment model, the collected training data can be divided into working conditions, and the health assessment model can be obt...

Abstract

The invention discloses a method and device for maintaining health of an elevator door system. The method comprises the following steps: collecting current signals in the working process of an elevator door in real time; extracting prediction features from the current signals; screening the prediction features to obtain effective features; and inputting the effective features into a pre-established health evaluation model, and obtaining a health value of the elevator door according to the output of the health evaluation model. According to the method and the device, accidental fault shutdown of the elevator door can be reduced, and the running safety of an elevator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of industrial predictive maintenance, in particular to a method and device for health maintenance of an elevator door system. Background technique [0002] Elevators are an indispensable means of transportation in people's daily life. With the continuous development of social economy and the rapid increase in the number of high-rise buildings in cities, elevators will be used more widely. The elevator door is an important component of the elevator. The elevator door generally adopts a split door, which is divided into a landing door and a car door. It is an important safety device to prevent people and objects from falling into the shaft. Composed of sliders and other components. Its working principle is to rely on the motor to drive the pulley block through the belt to realize the opening and closing of the elevator door. However, due to the high frequency of use of the elevator door and the diversity of ...
