Abstract:Electricity is an important part of power transmission line operation and maintenance management, the traditional power line patrol patrol patrol auxiliary depends on the operation model of the host, the inspection precision, line measurement accuracy, a long period of time is difficult to guarantee the operation; patrol aircraft to ease the operation pressure to a certain extent, solve the transmission line channel is approximately to check the situation, but yet to achieve accurate inspection tree barrier, airborne LiDAR technology makes the transmission operation mode can be improved, as a new measure to make precise measurement of the dangerous point of transmission channels as possible, this paper discusses the problems of traditional transmission line operation and maintenance work efficiency, safety and work intensity, combined with the characteristics of the airborne LiDAR technology in the electric power engineering survey into danger point diagram and transmission channel detection and analysis technology realization process and application, research on laser point cloud data According to the rapid processing and classification, we can realize the transmission channel environment and flight and measurement, further improve the speed of operation and emergency response and the accuracy of hidden danger determination, so as to reduce the investment in operation and maintenance, and improve operation and maintenance efficiency.
