Abstract

The invention discloses a high-voltage double circuit transmission line unmanned aerial vehicle tour inspection and obstacle avoidance method based on electric field intensity change rate. A brand-new theory that change rate of electric field intensity around a transmission line is mainly determined by a conductive wire arrangement mode and an erecting structure is provided, based on which the obstacle avoidance method is obtained so that accuracy of obstacle avoidance can be enhanced and the obstacle avoidance method can be greatly simplified.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle inspection and obstacle avoidance method, in particular to an unmanned aerial vehicle inspection and obstacle avoidance method for a high-voltage same-tower double-circuit transmission line based on the rate of change of electric field intensity. Background technique [0002] With the rapid development of my country's power grid, the voltage level of high-voltage transmission lines is getting higher and higher, the transmission length is getting longer and the terrain and landforms it passes through are becoming more and more complex. Unmanned aerial vehicles have the advantages of not being restricted by the terrain and environment, and have the advantages of high cost-effectiveness. At the same time, there is no need to worry about casualties on board caused by accidental crashes of aircraft. Therefore, in order to improve the efficiency of power grid inspections and to solve the real threat to powe...
