Method and system for detecting broken strands and scattered strands of distribution line wire

Abstract

The invention relates to a method and a system for detecting broken strands and scattered strands of a distribution line wire. The method comprises the following steps: preprocessing a machine patrol conductor image, and determining the preprocessed conductor image; segmenting the preprocessed lead image, and determining a segmented lead image; determining a lead in the segmented lead image by using a Hough straight line detection method; performing feature extraction on the wire, taking the extracted wire features as input of a support vector machine, and outputting a defect area in the wire, wherein the lead features comprise information entropy, color, texture and a shape bottom layer. According to the invention, the recognition rate of broken and loose strands of the wire is improved.

Description

technical field [0001] The invention relates to the field of detection of broken strands and loose strands of distribution line conductors, in particular to a method and system for detecting broken strands and loose strands of distribution line conductors. Background technique [0002] In recent years, with the rapid construction of China's power grid, in order to ensure reliable and stable power supply, it is necessary to conduct real-time tests on distribution lines, find abnormal conditions, and take corresponding measures to solve them. Conductors are the main equipment in the entire grid line, responsible for the transmission of electric energy in the grid, and their safe operation is related to the stability of the entire grid. The defect of disconnection of scattered wires is likely to cause a sharp increase in the power of the power line, resulting in disconnection or short circuit of the line. It is an important type of defect in the power line. Therefore, timely d...
