Elevator car door machine fault judgment method and system based on current monitoring technology

Abstract

The invention provides an elevator car door machine fault judgment method and system based on a current monitoring technology. The system comprises a current transformer, a collection board, a monitoring platform and terminal equipment. The method comprises the steps of acquiring real-time current data of a car door machine and processing and converting the real-time current data into a corresponding current value so as to generate monitoring data, and uploading the monitoring data to the monitoring platform; meanwhile, judging the obtained current value according to a preset rule, and when itis judged that a fault occurs, generating a corresponding fault code and uploading the fault code to the monitoring platform, wherein the monitoring platform is provided with fault description information corresponding to the fault code; when the fault code is received, matching the fault code with the corresponding fault description information, and then displaying the fault code and the fault description information; and providing an information sharing interface which is used for allowing the terminal equipment to have access to and transmitting the real-time monitoring data, the fault code and the corresponding fault description information to the terminal equipment by the monitoring platform.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a fault judgment method and system for an elevator car door machine based on current monitoring technology. Background technique [0002] With the continuous development of modern cities, there are more and more high-rise buildings such as supermarkets, hotels, and office buildings, resulting in an increasing number of elevators and an increasing frequency of use. Elevators have become an indispensable means of transportation for people to travel. tool. The increase in the overall number and frequency of use leads to an increasing probability of elevator failure. Ensuring the personal safety of passengers has become the focus of the entire industry, and the safety requirements for elevators are getting higher and higher. As labor costs continue to rise, the longer the elevator stops, the more service fees need to be paid. The elevator stopping will indirectly cause...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the systems on the market for monitoring the current of the car door machine are integrated in the elevator system, and the functions are limited by the elevator brands.

When the elevator installed by the user has multiple elevator systems, it is necessary to install a variety of monitoring equipment, which is too expensive and has limited functions, and in the process of use, there may be problems with the protocol mismatch between the elevator system and the monitoring system

The shortcoming of prior art has: 1) the source great majority of its system monitoring data is all based on the sensor that its elevator control system itself carries and running state, and this monitoring function is restricted by the brand of elevator, when the elevator that the user installs has multiple Elevator system requires the installation of various monitoring equipment, which is too expensive

2) The fault early warning reported by the system is only judged according to the service life and use time of the elevator components, and it cannot realize real-time monitoring and early warning

3) For most of the existing products on the market, data monitoring is local, and it is impossible to realize remote monitoring of elevator status and data sharing

4) Physical wiring, the data from the car top to the machine room needs to be routed separately, which is troublesome to install
