Abstract

The invention discloses a defect diagnosis method and system based on detection data of electric power inspection equipment, and belongs to the technical field of electric power diagnosis. The method comprises the steps of obtaining a first visible light image, a second visible light image and an infrared image, shot by a first visible light camera, a second visible light camera and an infrared thermal imaging camera, of tested electrical equipment; converting the infrared image into a standard infrared image in a preset image format; pre-processing the first visible light image, the second visible light image and the standard infrared image, and respectively carrying out image registration on the first pre-processed visible light image and the pre-processed infrared image as well as the second pre-processed visible light image and the pre-processed infrared image to obtain a first registration image and a second registration image; registering the first registration image and the second registration image to obtain a final registration image; performing fusion denoising on the final registration image to obtain a target image; and performing defect diagnosis on the target image according to a preset guide rule. The effect of improving the diagnosis accuracy is achieved.

Description

technical field [0001] The present application relates to the technical field of electric power diagnosis, and in particular to a defect diagnosis method and system based on detection data of electric power inspection equipment. Background technique [0002] Power equipment is one of the most important devices in modern industrial production. Once the equipment fails, it may cause the paralysis of the industrial system and cause major economic losses. [0003] At present, the electrical equipment of the power system is mainly diagnosed through regular preventive tests. However, with the development of electrical equipment and changes in economic needs, these traditional diagnostic methods have fallen behind, and the tested equipment needs to be powered off during the test, which cannot fully reflect the electric field, temperature, Due to the influence of the environment, etc., it is not easy to find the defects of the equipment in the running state, and there are shortcomi...
