TRANSMISSION LINE INSPECTION SYSTEM USING UNPILOTED PLANE AND METHOD USING IT

PROBLEM TO BE SOLVED: To provide a transmission line inspection system using an unpiloted plane capable of automatically inspecting whether a cap defect and a crack are caused in the insulator used in a transmission line. SOLUTION: The transmission line inspection system is equipped with a flight control system flying to the inspection place of the transmission line while autonomocisely flies, an unmanned helicopter equipped with a data collecting system for collecting various data containing a sound caused when a wood piece is allowed to impinge against the insulator of the inspection place, a control center equipped with a flight control/data collecting system for controlling the flight of the helicopter and collecting various data from the unmmaned helicopter to process the same and an insulator cap defect and the crack an insulator cap defect/crack inspection means 100 for subjecting the sound generated when the wood piece is allowed to impinge against the insulator collected by the data collecting system of the unmanned helicopter, to frequency analysis to detect the peak frequency of the sound to inspect whether there is the cap defect and crack is present in the insulator on the basis of the detected peak frequency.
