An online elevator ride quality inspection system and method

Abstract

The invention discloses an online elevator taking quality detecting system and method. The online elevator taking quality detecting system comprises a remote service terminal, an infrared sensor arranged in an elevator car, a door sensor installed at the position of a door motor of the elevator car, an elevator running state collecting module installed on the top of the elevator car and running along with an elevator, and elevator car terminal equipment. The output end of the infrared sensor, the output end of the door sensor and the output end of the elevator running state collecting module are connected with the elevator car terminal equipment, and the output end of the elevator car terminal equipment is connected with the remote service terminal through a wireless network. When the elevator runs in an idle manner, the elevator car terminal equipment collects related data in the process from starting to stopping of the elevator at a time in time and packages the related data according to a certain protocol, the related data is sent to the remote service terminal through the wireless network to be processed by the remote service terminal, and the elevator taking quality result isobtained. By means of the online elevator taking quality detecting system and method, the elevator running performance can be efficiently monitored on line, and reliable quantitative indexes are provided for analysis and evaluation of the elevator running quality.

Description

[0003] At present, there are nearly 300 elevator manufacturers and parts manufacturers in my country, thousands of units engaged...

AI Technical Summary

Problems solved by technology

However, there are the following problems: the staff engaged in elevator maintenance are mixed, and the prediction of elevator failure is not very accurate; although some large enterprises have their own dedicated maintenance personnel, the sales area of ​​these companies is relatively wide, and the technology It is difficult for personnel to regularly maintain the elevators installed by the company

Although the EVA-625 system can simultaneously collect the three-dimensional vibration acceleration of the elevator in real time, the subsequent data analysis needs to rely on the computer and the special EVA vibration analysis tool software, and the detection results cannot be directly observed during the detection, which affects the detection efficiency; and EVA-625 is an off-line detection instrument, which can only detect the current situation of the elevator; in addition, EVA-625 is expensive and cannot be widely used in large areas at present
