Method for acquiring images of electric power equipment on basis of multispectral sensor groups

Abstract

The invention provides a method for acquiring images of electric power equipment on the basis of multispectral sensor groups. The method includes steps of 1), acquiring image information, to be more specific, acquiring spectral information and site information by the aid of collection units comprising multisource sensors and carrying out data preprocessing on acquired information of the sensors bymeans of data conversion and fusion; 2), storing and managing the information, to be more specific, judging types of equipment images acquired from different sources and constructing image data storage structures; 3), analyzing information types, and to be more specific, providing extensible interfaces for general image operation such as image retrieval and image rough classification on basis oftexts and contents for follow-up image processing operation by the aid of image analysis interfaces; 4), outputting results, and to be more specific, judging and outputting the detection results by the aid of a data processor. The method has the advantages that image data can be efficiently utilized when multispectral images of power transformation equipment are analyzed, accordingly, safe and reliable operation of power grid equipment can be guaranteed, and the method has high theoretical and practical significance.

Description

technical field [0001] The invention relates to the technical field of application methods of visible light spectrum of electric power equipment, in particular to an image acquisition method of electric power equipment based on a multi-spectral sensor group. Background technique [0002] With the rapid development of my country's economy, UHV, AC-DC hybrid, and a large number of new energy sources have become the inevitable development trend of the power grid. At present, my country's power grid covers a very large area, and the number of various substation equipment is also huge, such as substations, conductors, towers, etc. The number has increased significantly, and the distribution range is wide and the distance is long. It is obviously impossible to rely entirely on manual maintenance. At the same time, the requirements for the unified management and monitoring of these substation equipment have also increased. On this basis, the rapid development of unattended substat...

Problems solved by technology

[0006] However, in practical applications, through visible light, infrared, ultraviolet and other multi-spectral detection analysis and identification technologies, some problems in the current online monitoring of substation equipment can be fundamentally solved: the operating parameters of important equipment need to be monitored in real time, and manual inspection is used It is difficult to meet the real-time requirements. The sense of responsibility, work attitude and mental state of the inspectors have seriously affected the detection results; the operating status of many high-voltage equipment is difficult to convert into electrical signals, and they are easily affected by strong electromagnetic field interference during signal conversion and transmission. Diagnosis: The use of infrared to detect equipment is still at the simple application level of temperature records. It is not associated with equipment status, and historical data is difficult to store and retrieve. In addition, it is difficult for human eyes to distinguish the grayscale changes of subtle images, and it is difficult to analyze substation equipment objectively. degree of surface defects
