The invention discloses a defect diagnosis method and system for substation equipment based on a video image intelligent front end. The method includes: collecting video images of the substation equipment in real time; adopting an optimal scheduling scheme, executing a lightweight defect recognition model to process the video images, and determining defects of the substation equipment according to the processing results. This method utilizes the edge computing capability set on the side of the intelligent front end to process video images in real time. Use the video image processing chip integrated in the intelligent front end to execute the fault image diagnosis algorithm of substation equipment, and generate the early warning conclusion or defect identification conclusion of the substation equipment status; realize fast and efficient image processing on the side and end side, and ensure the fault diagnosis of substation equipment speed, timeliness and accuracy.
Description
technical field [0001] The invention belongs to the technical field of intelligent inspection of power transformation equipment, and in particular relates to a defect diagnosis method and system for power transformation equipment based on a video image intelligent front end. Background technique [0002] At present, there are the following problems in the inspection and analysis of substation equipment: [0003] 1. There is a lack of means for intelligently collecting video images of substation equipment. In the early stage of development of substation equipment inspection, hand-held infrared thermal imagers, hand-held ultraviolet imagers and manual inspection methods are usually used to improve the ability to detect equipment defects, but increase the daily inspection work pressure of inspection personnel, and also impose a burden on inspection personnel. Higher technical requirements are put forward. With the construction of smart substations, video image inspection term...
