Switch cabinet real-time monitoring method and system based on cable joint and ambient temperature of cable joint

Abstract

The invention relates to the field of image acquisition, in particular to a switch cabinet real-time monitoring method and system based on a cable joint and ambient temperature of the cable joint, andthe method comprises the steps: a camera collects the image information of the cable joint and the ambient temperature, and obtaining a first visual image; an infrared array camera collects temperature dot matrix information of a cable joint and surrounding temperature in the switch cabinet to obtain a first temperature array image; calibration processing is performed on the two images, and the two images are fused according to the feature points; a real scene in the fused image is displayed through the grayscale image, and the temperature information is displayed by using the chromaticity value of the pixel to obtain a final display image; and the switch cabinet is monitored in real time according to the final display image. The situation of the cable joint and the surrounding temperature gradient can be obtained through the final display image, and a reliable basis is provided for fault diagnosis of the switch cabinet.

Description

technical field [0001] The invention relates to the field of image acquisition, in particular to a method and system for real-time monitoring of a switch cabinet based on a cable joint and its surrounding temperature. Background technique [0002] During the operation of the power distribution switchgear, the busbar connection head and other parts will cause excessive contact resistance and heat due to long-term heavy load, aging and other reasons. If it is not handled in time, it may eventually cause fire and large-scale power outage due to overheating. occur. In the actual operation process, it is necessary to monitor its temperature, so that the operation and maintenance personnel can understand the operation status of the equipment early, find problems in time and take corresponding measures to avoid economic losses and safety accidents. [0003] At present, the temperature detection of cable joints in switch cabinets is usually monitored by two methods: regular inspect...

AI Technical Summary

Problems solved by technology

[0004] 1. Solve the problem of single-point temperature detection, but it does not take into account the detection of the surrounding environment temperature: no matter whether it is inspection or contact and non-contact temperature inspection, it solves the problem of point temperature measurement, but does not solve the problem of the entire switch joint. temperature check;

[0005] 2. Only a single temperature information is provided, and there is no real-time temperature measurement scene display: only a single temperature information is displayed. As for the location of the temperature detection point, the surrounding temperature gradient changes, etc. are difficult to obtain
