Abstract
By using Beidou high-precision positioning technology, drone autonomous flight technology, and drone communication technology, a drone inspection system has been constructed. In order to further improve the work efficiency of UAV inspection on transmission lines, a single-base tower UAV inspection track optimization method based on the filtering method of the sphere unit limit is proposed. With the assistance of precision positioning services, the autonomous drone inspection hovering accuracy can reach an average of 5cm (E-W), 6cm (N-S), and 7cm (H), which meets the requirements of fine line inspections. The method proposed in this paper can further improve the efficiency of UAV fine independent inspection while improving the intelligent level of transmission line inspection.
Highlights
Unmanned Aerial Vehicle (UAV) is widely used in the operation of remote, dangerous and complex area because of its advantages of small volume, low price, easy to control and flexible
The key of UAV autonomous inspection lies in making UAV patrol track in advance, combining with UAV flight safety, shooting distance and other constraints to carry out track planning[6,7]

Summary
Unmanned Aerial Vehicle (UAV) is widely used in the operation of remote, dangerous and complex area because of its advantages of small volume, low price, easy to control and flexible. The key of UAV autonomous inspection lies in making UAV patrol track in advance, combining with UAV flight safety, shooting distance and other constraints to carry out track planning[6,7] Under this background, this paper takes single base tower as the basic unit and optimizes the track according to the characteristics of the track. The method proposed in this paper can further improve the efficiency of UAV fine independent inspection while improving the intelligent level of transmission line inspection This system deeply researches the standardized inspection path of UAV substations, autonomous control system of UAV, communication mechanism of UAV control and management method of autonomous UAV inspection results, forming UAV on-duty autonomy in UAV substations inspection system.
