A power channel inspection method based on fuzzy path

Abstract

The invention discloses a power channel inspection method based on a fuzzy path, which comprises the following steps: Step 1: Obtain the fuzzy path information required for the power channel inspection from a map; Step 2: Send the path information to no one in a wireless manner machine; Step 3: The UAV flies to the vicinity of the first inspection point in the path, recognizes the target based on machine vision, and judges the position and height of the UAV itself according to the parameter characteristics of the target; Step 4: None After the man-machine reaches the designated position and height, adjust the proportion of the target in the screen through the focal length adjustment algorithm and take pictures and identify defects; Step 5: Repeat Step 3 and Step 4 until the inspection operation of all path points is completed; Step 6: The UAV returns and lands. The inspection method simply selects key path points on the map to form a fuzzy path information, eliminating the need for manual collection of path information or 3D point cloud data to set path information, saving manpower and material resources and improving efficiency.

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....

AI Technical Summary

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
