Abstract

The invention discloses an unmanned inspection and obstacle avoidance method for high-voltage single-circuit transmission lines on the same tower based on the rate of change of electric field intensity. It proposes a brand-new change rate of electric field intensity around the transmission line, which is mainly determined by the arrangement of the wires and the structure of the tower. Determining the theory and thus obtaining the obstacle avoidance method, thereby improving the accuracy of obstacle avoidance, and greatly simplifying the obstacle avoidance method.

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 single-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...
