In order to improve the operation reliability of the distribution network overhead lines in xiong’an new area

the autonomous inspection technology of unmanned aerial vehicle（UAV）and intelligent inspection platform based on UAV for distribution overhead lines were studied in this paper.The path planning algorithm based on the key coordinate points is used to plan the distribution network lines to ensure the accuracy of UAV autonomous inspection.The autonomous inspection of UAV is carried out in areas difficult to reach by inspectors

such as Lake area

construction site and farmland.By carrying high-definition camera and infrared thermal imager

the perception ability of UAV can be improved.The foreign matters

bird’s nests and fever of equipments can be found in time

then the inspection efficiency of distribution network overhead lines can be improved.
