Autonomous inspection method of unmanned aerial vehicles for overhead distribution lines based on GNSS-PPK positioning
This paper focuses on unmanned aerial vehicle autonomous inspection method for GNSS-PPK positioning of overhead distribution lines.Firstly,using GNSS-PPK positioning technology with strong anti-interference capability,receiving satellite signals and calculating the position and speed of the receiver to obtain high-precision data on overhead power distribution lines.Secondly,based on the actual situation of overhead power distribution lines,the data will be used to determine the path for autonomous inspection by drones.During the flight,adjust the flight altitude of the drone through control algorithms.At the same time,dynamically adjust the tolerance distance according to the actual situation to adapt to different environmental conditions and needs.Experimental results have shown that the accuracy of unmanned aerial vehicle autonomous inspection of overhead distribution lines using GNSS-PPK positioning is at the centimeter level,which can effectively improve the accuracy of unmanned aerial vehicle autonomous inspection.
