Problems solved by technology

[0004] However, the current infrared thermal imaging technology used for fault diagnosis of power system equipment is still mainly based on hand-held infrared imagers, relying on manual analysis of infrared images to diagnose thermal faults of electrical equipment, which cannot meet real-time requirements. Intelligent monitoring requirements, and this detection method requires high operator experience and professional knowledge, low efficiency and error-prone

Abstract

The invention provides a substation equipment defect recognition method and device, and particularly relates to the technical field of data analysis and processing, and the method can comprise the steps: building an infrared and visible light double-vision system, and obtaining a visible light image and an infrared image of detected substation equipment; carrying out the fusion through employing an image fusion algorithm of IHS transformation and Contourlet transformation, and generating a to-be-recognized image after fusion; constructing a neural network, performing feature extraction on the batch of original video data, and establishing an equipment defect database including abnormal data of the power transformation equipment in different states; then constructing a transfer learning network based on infrared image features to obtain a temperature mode analysis result of the equipment area; and finally, carrying out anomaly identification and defect judgment on the to-be-recognized image by utilizing a multi-network fusion algorithm. Based on the scheme provided by the invention, the intelligent degree of substation equipment fault detection is improved, and the efficiency and accuracy of fault detection are improved.

Description

technical field [0001] The invention relates to the technical field of data analysis and processing, in particular to a method and a device for identifying defects of substation equipment. Background technique [0002] Electric power is a basic industry, and the supply and stability of electric power is the key part of the electric power industry. Substation equipment is an important part of the power system, and its safe and stable operation is an important factor to ensure the reliability of power supply. Due to the long-term operation of substation equipment and the influence of environmental factors, various failures often occur. Therefore, it is one of the important means to ensure the reliable operation of substation equipment and power grid to conduct patrol inspection of substation equipment, and analyze and diagnose according to its status. [0003] Infrared thermal imaging detection technology is an effective means to monitor the thermal state of electrical equip...
