Abstract: In recent years, 5G technology and its application have been discussed and explored intensively worldwide. The features of high bandwidth, low delay, high precision and wide airspace endowed by 5G can help UAV (Unmanned Aerial Vehicle, UAV) make up more shortfalls, unlock more application scenes and meet the requirements of power transmission line inspection. By using UAV with 5G communication ability in 5G network environment, this paper realizes UAV automatic transmission line inspection, drones VR (Virtual Reality, VR) inspection and intelligent linkage application scenarios, which can truly achieve 5G UAV in the application of power transmission line inspection, and reduce labor costs, improve the quality of power transmission line inspection, timely find out problems in transmission lines and the surrounding environment, guarantee the safe operation of transmission lines.
