Elevator fault intelligent diagnosis system and method

Abstract

The invention provides an intelligent diagnosis system for elevator failure. The intelligent diagnosis system comprises a detecting device and a server, wherein the detecting device is used for sampling and detecting elevator car operation three-dimensional original data to obtain elevator operation state data, and sending the elevator operation state data to the server; the server fits a corresponding elevator operation fitting curve according to the received elevator operation state data; and a vibration anomaly point is searched on the elevator operation fitting curve, so that vibration anomaly sections are separately formed at front and rear sides of the vibration anomaly point, wherein the vibration anomaly sections represent elevator failure. The intelligent diagnosis system can automatically detect elevator failure, and can further automatically judge some failure reasons.

Description

technical field [0001] The invention relates to the field of elevator detection equipment, in particular to an elevator fault intelligent diagnosis system and method. Background technique [0002] As the speed of urbanization accelerates, tall buildings rise from the ground, and elevators as a means of vertical transportation are also widely used, followed by a huge amount of elevator installation and maintenance work. [0003] During the installation or use of the elevator, there may be abnormal vibration during the operation of the elevator due to factors such as balance coefficient, wear of the traction machine chute, wear of the traction rope, and lack of oil in the bearing. Passengers feel uncomfortable, and serious safety hazards will be left to affect the personal safety of passengers. [0004] For the abnormal vibration of the elevator found during the installation and commissioning process, the general installers can find and solve the problems one by one in combin...

AI Technical Summary

Problems solved by technology

[0003] During the installation or use of the elevator, there may be abnormal vibration during the operation of the elevator due to factors such as balance coefficient, wear of the traction machine chute, wear of the traction rope, and lack of oil in the bearing. Passengers feel uncomfortable, which will leave a safety hazard and affect the personal safety of passengers

[0004] For the abnormal vibration of the elevator found during the installation and commissioning process, the general installers can find and solve the problems one by one in combination with the elevator’s installation and construction drawings and installation and commissioning conditions, but this method often requires a lot of manpower and time. The installation and commissioning cost of the elevator increases, which also affects the delivery and use schedule of the elevator

[0005] For the abnormal vibration of the elevator during use, the general maintenance personnel cannot get feedback immediately, which will not only make passengers feel uncomfortable, but also cause potential safety hazards in the subsequent use of the elevator with abnormal vibration

Even if the maintenance personnel arrive at the scene, they still need to check whether the traction rope at the shaking position is worn, whether the bearing is short of oil, whether the traction machine groove is worn, etc., but troubleshooting these problems will inevitably take a lot of time for the maintenance personnel, and the work efficiency will increase. extremely low
