Equipment operation abnormity judgment method

Abstract

The invention discloses an equipment operation abnormity judgment method. The method comprises the steps of step 1, acquiring the acceleration data of equipment when the equipment operates in the setdirection, filtering the acquired acceleration data to filter out the data of the equipment when the equipment is in the static state; step 21, generating an acceleration curve in the set direction according to the acceleration data, and cutting out the acceleration curve to obtain an acceleration curve of operating actions; step 22, dividing the acceleration curve into a plurality of subsegmentsaccording to the slope changes and acceleration direction changes of one single acceleration curve of each group; and step 23, judging whether equipment operation is abnormal according to the acceleration characteristics represented by the acceleration curve in each subsegment. With the equipment operation abnormity judgment method, the acceleration data of equipment can be acquired according to the operating conditions of the equipment, then whether equipment operation is abnormal or not can be judged according to the acceleration data, whether the equipment has a failure or not can be judged, the abnormal conditions might cause equipment failures can be found at the same time, and it is effectively guaranteed that the equipment is safe to use.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and relates to an abnormal judgment system, in particular to a method for judging abnormal operation of equipment. Background technique [0002] Elevator is the most commonly used vertical transportation vehicle in modern high-rise buildings. It saves people's time and physical strength and provides convenience for daily life. As a special equipment that is closely related to the safety of public life, the safe operation of elevators has attracted more and more attention from the society. However, due to the complex structure of the elevator, it is an urgent need for elevator management, maintenance and safe operation to ensure the safe and reliable operation of the elevator and to detect its operating status and fault conditions. [0003] According to the statistics of China Industry Information Network, at present, China is the world's largest producer and consumer of elevators, a...

AI Technical Summary

Problems solved by technology

[0007] a. The real-time elevator operation information collected by the system is transmitted through wireless communication networks such as China Mobile, China Unicom or China Telecom, so the data flow is quite large. In addition, the wireless network operator charges according to the traffic, so that the operation of this elevator remote monitoring system High cost, unable to achieve 24-hour uninterrupted monitoring

[0008] b. Simple functions, no database management function, only simple elevator operation status monitoring, no maintenance and quality management monitoring function, no early warning of elevator failure

[0009] c. The system compatibility is poor, and it can only be deployed and controlled for a small number of elevator types, and cannot accurately analyze and judge elevator faults, and cannot accurately give the specific fault location of the elevator

[0010] Existing monitoring methods are usually through the camera installed in the elevator, or by receiving the alarm signal sent in the elevator to understand the situation in the elevator; it is impossible to predict the elevator failure
