Abstract

Abstract: To satisfy need of distribution network overhead transmission lines inspection, an Unmanned Aerial Vehicle (‘UAV') comprehensive inspection method is proposed. The construction of UAV inspection platform is analyzed. Configuration requirements of visible light sensor, infrared sensor, ultraviolet and ultrasonic sensor and UHF sensor are researched and confirmed. Test result suggest that UAV inspection system has ability to operate normally in environment temperature from -20 ℃ to 45 ℃. The height limit is 2 000 m with 7 m/s wind loading rating. The hover accuracy is 0.5 m on vertical direction and 1.0 m on horizontal direction which can pinpoint electric tower inspection. The visible light sensor, with 12 million effective pixels, is equipped with variable focal length and variable focal length and auto-focusing function. The infrared sensor, with 300 thousand effective pixels, is equipped with auto-focusing function. The proposed UAV inspection platform can be applied in distribution network overhead transmission lines inspection to improve automation and intelligent level.

Key words: distribution network overhead transmission lines, UAV comprehensive inspection, sensor module, environmental suitability, inspection function
