Electric power channel inspection method based on fuzzy path

Abstract

The invention discloses an electric power channel inspection method based on a fuzzy path. The method comprises the following steps: 1, acquiring fuzzy path information required by electric power channel inspection from a map; 2, sending the path information to the unmanned aerial vehicle in a wireless mode; 3, the unmanned aerial vehicle flying to the position near a first inspection position point in the path, recognizing a target object based on machine vision, and judging the position and height of the unmanned aerial vehicle according to parameter characteristics of the target object; 4, after the unmanned aerial vehicle arriving at the designated position and height, adjusting the proportion of the target in the picture through a focal length adjustment algorithm, photographing and identifying defects; 5, repeating the step 3 and the step 4 until the inspection operation of all the path points is completed; and 6, the unmanned aerial vehicle returning and landing. According to the inspection method, the key path points are simply selected on the map to form fuzzy path information, the link of manually collecting the path information or setting the path information through three-dimensional point cloud data is omitted, manpower and material resources are saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle flight control, in particular to a power channel inspection method based on fuzzy paths. Background technique [0002] With the continuous development of the economy, the length of the transmission line is also expanding. It is mainly composed of foundations, towers, wires, insulators and fittings. Defects such as insulator damage, broken strands, and missing wires in the line can easily cause line faults. Industrial production has caused irreparable losses, and people's daily life has brought great inconvenience. In order to ensure the safe and stable operation of the transmission line, the power supply company formulates a line inspection plan according to the line operation situation, and the line maintenance personnel will carry out transmission line inspections according to the line inspection plan. [0003] At present, more and more tower inspections are carried out by UAVs....

Problems solved by technology

[0006] The traditional manual inspection method has the problems of low inspection accuracy and low efficiency; on the other hand, inspection personnel control drones to conduct inspections, which takes a long time, consumes a lot of manpower and material resources, and In the case of low personnel security, autonomous inspections require path planning in advance. At present, there are two main path planning methods: one is to use 3D point cloud data for modeling, and the inspection path is planned with the help of 3D models; the other is to use Manually collect waypoints in advance to generate route information, both of which require a large investment in personnel or equipment in the early stage
