Abstract

The invention provides a power line patrol unmanned aerial vehicle navigation system based on GPS RTK technology. The power line patrol unmanned aerial vehicle navigation system comprises one or a plurality of unmanned aerial vehicle movement stations, a plurality of reference station subsystems and a ground station monitoring subsystem. The plurality of reference station subsystems are respectively configured on power line towers, wherein the plurality of reference station subsystems are used for transmitting GPS differential data to the unmanned aerial vehicle movement stations through a wireless data transmission system. The unmanned aerial vehicle movement stations are used for obtaining centimeter-grade-precision navigation information through the GPS RTK differential technology. Furthermore real-time monitoring for the unmanned aerial vehicle movement stations and each reference station subsystem by the ground station monitoring subsystem is realized through the wireless data transmission system.

Description

technical field [0001] The present invention relates to power equipment and unmanned aerial vehicle navigation technology, more specifically, relates to a kind of electric line patrol unmanned aerial vehicle navigation system based on GPSRTK technology. Background technique [0002] For power lines that pass through virgin forest edge areas, high altitudes, and snow-covered areas, there are frequent landslides, mudslides and other geological disasters along some lines, and most areas have high mountains and steep slopes. When transportation and communication are extremely underdeveloped, daily inspections of power lines become a difficult task. [0003] The traditional power line and pipeline inspection process is that the staff go to the site to inspect the line in person. The inspection objects are mainly power facilities, including towers, wires, transformers, insulators, crossarms, knife switches and other equipment, and the inspection situation is recorded in the form o...
