Research on Real-Time Monitoring and Early Warning Technology of Transmission Line External Force Damage Based on Three-Dimensional LiDAR

Power transmission line is an important channel for power transmission, and in recent years, external damage accidents have been increasing, which seriously affects the safe operation of transmission lines and the reliability of power supply. The traditional external damage monitoring means can not be 24/7 uninterrupted monitoring, low efficiency, and can not grasp the spatial distance between the external damage target and the power line, the monitoring effect is not good. In this paper, the real-time monitoring and early warning technology of external damage targets on transmission lines is studied, which deeply integrates the laser point cloud and visual images to realize the identification and localization of external damage targets on transmission channels and the distance monitoring. In this paper, different transmission lines are selected as typical external damage scenarios, and the test results show that the error of the online measurement distance of the channel damage target is no more than 25cm, which can be better applied to the external damage prevention and monitoring of transmission lines to ensure the safe and stable operation of transmission lines.
