Method and device for intelligently diagnosing image through fixed-point, fixed-focus and fixed-parameter detection of GIS equipment through digital rays

Abstract

The invention discloses a method and device for intelligently diagnosing an image through fixed-point, fixed-focus and fixed-parameter detection of GIS equipment through digital rays. The method comprises the following steps: (S1) photographing a digital ray standard image of a part of the GIS equipment in a normal state, and recording the angle, the distance, the focal length, the pipe voltage and the pipe current during the photographing; (S2) photographing s digital ray detection image of the part of the GIS equipment in a to-be-diagnosed state, wherein the photographing angle, distance, focal length, pipe voltage and pipe current are same as the photographing angle, distance, focal length, pipe voltage and pipe current of the digital ray standard image; and (S3) synchronously scanningthe standard image and the detection image, determining whether the two images have structural differences through comparison, and if yes, marking for warning. According to the method, the standard image and detection image of the part of the GIS equipment are photographed in fixed-point, fixed-focus and fixed-parameter manners and are subjected to synchronous correlation, scanning and contrastiveanalysis, so that compared with an existing manual diagnostic method, the method has the advantages of convenience in operation, precision in comparison and high detection efficiency.

Description

technical field [0001] The invention relates to a method and device for detecting GIS equipment with fixed-point, fixed-focus and fixed-parameters of digital ray to realize image intelligent diagnosis, and belongs to the field of digital ray detection of GIS equipment. Background technique [0002] X-ray inspection of GIS equipment using digital radiography system is a new inspection technology that has emerged in the power system in recent years. The advantages of greatly reducing the dose, storing, managing, transmitting, and displaying images and related information in a digital electronic manner are beyond the reach of traditional film technology. Due to the complex structure of GIS equipment, there are many types of materials (such as copper, steel, aluminum, ceramics, polymer materials), and a wide range of thickness variations. At present, the diagnosis of GIS equipment is to first take digital radiographic images of each part of the equipment, and then compare it wi...
