Differential-GPS-based unmanned-aerial-vehicle autonomous routing inspection system and method for power transmission line

Abstract

The invention discloses a differential-GPS-based unmanned-aerial-vehicle autonomous routing inspection system for a power transmission line. The system comprises an unmanned aerial vehicle and a ground station control system. A flight control system of the unmanned aerial vehicle receives waypoint information generated by a tower autonomous routing inspection waypoint generation system of the ground station control system; and according to the waypoint information, the flight control system is controlled to carry out flight, wherein the waypoint information consists of the flight latitude and longitude, the altitude, the plane head orientation, and the cloud platform angle orientation of the unmanned aerial vehicle. According to the invention, the power transmission tower can be identified precisely by using the geographic information technology; the unmanned aerial vehicle platform can be localized precisely during flight by using the differential GPS positioning technology; the routing inspection point can be solidified by using the power transmission tower routing inspection technology; and the cloud platform angle displacement can be controlled precisely by using the control technology. Therefore, unmanned-aerial-vehicle autonomous routing inspection system and routing inspection method of the power transmission line can be realized.

Description

technical field [0001] The invention relates to a differential GPS-based UAV autonomous inspection system and method for power transmission lines. Background technique [0002] In the past two or three years, with the construction of the smart grid, the intelligent inspection of transmission lines has also developed rapidly. The use of drones for inspections of transmission lines is nothing new, but in the process of inspections by drones, it also highlights Some problems have hindered the development of UAV inspection of transmission lines. Now there are two major problems facing UAV inspection: one is the difficulty of actual inspection and dare not fly; the other is difficult data processing in the later stage. The problem of not wanting to fly. If these two major problems are not resolved, it will be impossible to popularize drone inspections as a routine inspection method for transmission lines. The present invention is mainly aimed at the first problem, the actual in...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a transmission line UAV autonomous inspection system and method based on differential GPS, which solves the problem of autonomous inspection of barriers and transmission line towers. The precise positioning of GPS ensures that the flight control accuracy of the aircraft is within the range of 0.2m. Combined with the established basic information database of the tower, the inspection points of the tower are automatically generated, so as to achieve the full autonomous inspection of the drone for the inspection of the tower. check
