Embodiment 1
[0036] An intelligent fault diagnosis method for live equipment based on infrared thermal imaging, such as figure 1 As shown, the following steps are included: A) Acquisition of fixed-point and oriented infrared images 1 for all measured objects 5 in the target area with a handheld device. The method for collecting the infrared image 1 of the measured object 5 in the target area includes: collecting the unblocked infrared images 1 of the measured object 5 from multiple positions and multiple angles respectively. There are multiple image models 3 of the measured object 5, and only one of them can be selected for shooting, allowing the photographer to choose from multiple positions and angles, making shooting convenient and improving shooting efficiency.
[0037] B) Collect the infrared image 1 of each object, extract the boundary 2 of the image as the image model 3, and save the image model 3 to the image model 3 library. Such as figure 2 As shown, the method of extracting t...

The present invention relates to the technical field of infrared diagnosis of charged equipment, in particular to an intelligent fault diagnosis method for live equipment based on infrared thermal imaging, comprising the following steps: A) collecting infrared images once for all measured objects in the target area; B) extracting The boundary of the image is used as the image model; C) Associating the image model with the name of the object under test, the material of the object, the identification of the heating part, the heating type of the heating part and the defect information; D) Formulating and executing the inspection task, during the inspection process The measured object takes infrared image shooting, collects the infrared image of the measured object and saves it after correlating with the time stamp; E) imports the captured infrared image into the diagnostic system; F) the diagnostic system automatically compares the same type of measured object along the same line The temperature of the time axis is used to diagnose whether there is a fault in the measured object, and if there is a fault, an alarm will be issued. The substantive effects of the present invention are: realize unified data comparison, fully analyze detection data, and improve fault detection effect.
Description
technical field [0001] The invention relates to the technical field of infrared diagnosis of live equipment, in particular to an intelligent fault diagnosis method of live equipment based on infrared thermal imaging. Background technique [0002] Infrared detection is a conventional and effective detection method in live detection of power grid power equipment. It has the advantages of long-distance, non-contact and real-time imaging. In the whole detection process, infrared thermal imaging technology is used to detect power equipment. Infrared thermal images can detect possible thermal defects in equipment, predictively detect faults in electrical equipment, and avoid serious damage to electrical equipment. At present, infrared detection is widely used in power transmission and distribution systems of various voltage levels. Although power workers can judge infrared thermal defects of traditional power equipment based on the "Application Specification for Infrared Diagnosi...
