Automatic and Intelligent Line Inspection using UAV based on Beidou Navigation System

In this paper, the Beidou high-precision positioning technology, the autonomous inspection technology of the UAV and the communication technology of the UAV are used to construct the inspection architecture of the UAV autonomous inspection. The inspection architecture includes UAV inspection path standard planning and acquisition verification, UAV autonomous flight control system, UAV and application platform communication control, UAV inspection results identification and management. Based on high-precision positioning technology, we designed the architecture of the UAV autonomous inspection system, the UAV autonomous inspection security strategy and transaction processing mechanism, the UAV’s real-time video and position transmission system. Then we successfully developed the UAV Autonomous inspection system. After testing, based on high-precision positioning technology, the accuracy of the UAV autonomous inspection repeat flight can reach 5cm (EW), 6cm (NS), 7cm (H), and the stop point heading angle is 56″ on average, which can indicate that under the guarantee of this system, the UAV can carry an important role in inspection work safely and effectively.
