Prediction method of electrical fault image recognition based on infrared thermal imaging technology

Abstract

The present invention provides a method for predicting electrical fault image recognition based on infrared thermal imaging technology, which includes an infrared thermal imager and a high-definition camera, including: 1. When the elevator is working normally, the staff holds the high-definition camera to take pictures of the main board of the elevator Main board image, the size of the main board image is divided into Jiugongge blocks, and then the block images of each block of Jiugongge are taken by the high-definition camera; The thermal imaging image of the main board of the elevator, the thermal imaging image is divided into nine square grid blocks equal to the main board image, and then the block thermal imaging image of each block of the nine square grid is taken by the infrared thermal imager; the present invention utilizes Infrared thermal imaging technology performs real-time detection and early warning of elevator failures to improve maintenance efficiency.

Description

Technical field[0001]The present invention relates to an elevator test detection technique, particularly a pre-proportion method based on an electrical fault image recognition based on infrared thermal imaging techniques.Background technique[0002]The elevator control system fault occupies more than 60% of the elevator fault, and many faults do not prequister, as elevator maintenance personnel, the most fear is to exclude the control system failure, although some faults have fault code, the repair personnel can pass the fault code, more Quick discrimination of the cause of the failure. However, electronic components, safety switches, motors, contactors and circuit boards, and connectivity of these electronic devices may have a loose, contact ablation, aging, and moist (switch of the pit), which is easy to have some unforeseen faults. At the one hand, these faults affect the safety of the elevator, and these faults often do not easily troubleshoot or exclude them, resulting in repeate...

AI Technical Summary

Problems solved by technology

However, electronic components, safety switches, motors, contactors and circuit boards, and the connections of these electronic devices may be loose, contact ablation, aging, and moisture (switches in pits), prone to some unforeseen failures On the one hand, these faults affect the safety of the elevator, and at the same time, these faults are often not easy to check or not completely eliminated, resulting in repeated faults

Some small faults, such as damage to a small component or poor contact, but the maintenance personnel cannot completely eliminate the method of replacing the entire circuit board will increase the economic burden of the elevator owner, and many elevator disputes and fault complaints have occurred
