Elevator traction machine failure judgment method and system based on current monitoring technology

Abstract

The invention provides an elevator traction machine failure judgment method and system based on a current monitoring technology. The system comprises a current sensor, a signal box, a collection board, a data transmission gateway and a cloud platform server, wherein the current sensor is connected with the output end of a frequency converter of a traction machine; and the cloud platform server isprovided with a service interface for accessing a webpage or APP. The method comprises the following steps of acquiring real-time current data output by the frequency converter of the traction machine, and processing and converting the real-time current data into a corresponding current value; comparing the obtained current value with a preset running threshold, judging that an overcurrent failureoccurs when the obtained current value exceeds the running threshold, and feeding an overcurrent failure code to the cloud platform server; performing phase detection when no overcurrent failure occurs, and feeding the phase failure code to the cloud platform server when a phase failure occurs; and matching with corresponding failure description information by the cloud platform server accordingto the failure code, displaying the failure description information to the webpage or App.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator traction machine fault judgment method and system based on current monitoring technology. Background technique [0002] With the development of economy and the continuous increase of scale in modern cities, there are more and more high-rise buildings such as supermarkets, hotels and office buildings, resulting in more and more elevators, so people's safety requirements for elevators are also getting higher and higher. While the increase in the number of elevators has brought convenience to people entering and leaving high-rise buildings, the casualties and economic losses caused by elevator failures have also increased. Therefore, how to effectively implement the monitoring of the safe operation of elevators, and how to eliminate the hidden dangers of elevator failures in time have become the directions that all elevator manufacturers, users, and labor s...

AI Technical Summary

Problems solved by technology

[0004] 1. Remote real-time monitoring cannot be carried out, and maintenance personnel need to arrive at the scene to observe whether the traction machine is faulty

[0005] 2. The fault warning reported by the system is only judged according to the temperature and speed of the traction machine, and cannot effectively warn and monitor the abnormal operation of the traction machine at any time

[0006] 3. The monitoring system reports an error, and it is impossible to distinguish whether there is a sensor error in the monitoring system itself or the elevator is malfunctioning
