In order to realize the automatic inspection of power equipment by UAV based on UV imager, this paper designs a fully automatic hangar deployed near substations and transmission lines to realize remote control of UAVs, automatic landing and returning Positive, UV diagnostic defect data download and other functions. The hangar can transmit data with the UV imager, and send the data back to the PC, realizing one-click automatic acquisition of UV imaging data. The research results are of great significance to promote the development of UAV inspection in the power industry.
