Comprehensive monitoring device for the environment inside the elevator car

Abstract

The invention discloses a comprehensive monitoring device for internal environment of an elevator lift car. Elevator environment parameters and operation performance parameters are collected through asignal collecting module, the collected elevator environment parameters are filtered and amplified through a signal conditioning circuit, an environment quality evaluating module evaluates the environment quality according to the elevator environment parameters, an operation quality evaluating module evaluates the operation quality according to the amplified elevator environment parameters and the operation performance parameters, the evaluation result is displayed through a display module, and the environment quality evaluation result and the operation quality evaluation result are sent to amonitoring center through a communication module. According to the comprehensive monitoring device, a multi-sensor information fusion technology and a fuzzy reasoning theory and an evaluation algorithm of the lift car internal environment quality and the elevator operation quality are adopted, a monitoring device is designed based on an embedded system technology, and the lift car environment ofa passenger elevator can be conveniently and quickly monitored.

Description

technical field [0001] The invention relates to the field of elevator detection, in particular to a comprehensive monitoring device for the environment inside the elevator car. Background technique [0002] With the gradual popularization of elevators in urban life and the improvement of living standards, people's requirements for elevator operating performance and service quality have also increased. As the main carrier of passengers, the car is also the main place for passengers to experience and feel the quality of elevator operation. The performance parameters displayed during the operation of the elevator, such as acceleration, vibration, noise, etc., and the environmental parameters in the car, such as Temperature, humidity, lighting, air quality, etc. are all important factors that affect passenger experience. Furthermore, the overall quality of the elevator actually affects the changes of the above parameters to a certain extent. Factors such as the aging of the ele...

Problems solved by technology

[0004] However, the indicators of the existing monitoring devices are mostly single, and there is no in-depth analysis of the measurement data

In the case of a large number of elevators and insufficient maintenance personnel, it is difficult for the existing monitoring device to detect the comprehensive quality of the elevators in time
