输电运维班长李敏回应21：超高压电网线路巡检如何从“人巡”到无人机“智巡”

Core Viewpoint - The application of drone technology in power transmission inspection has significantly improved efficiency and safety, transitioning from manual to automated processes in the industry [1][3][4]. Group 1: Drone Technology Development - The team began exploring drone inspections in 2013, facing challenges such as complex structures and operational difficulties, initially achieving only 3-5 tower inspections per day [3]. - After several years of development, the drone inspection capabilities improved, allowing for the completion of inspections of 10 towers in half an hour, replacing manual inspections [3]. Group 2: Innovations in Drone Inspection - The team developed three key innovations: an autonomous navigation system for drones, a multi-spectral imaging system for defect detection, and an intelligent analysis system that achieves over 95% accuracy in identifying defects from inspection images [3][4]. - In 2021, the team deployed the first drone nest for autonomous inspections, enabling remote control of drones over distances of up to 4 kilometers without human intervention [4]. Group 3: Achievements and Future Prospects - By 2023, the team established 568 drone nests across the province, creating a collaborative inspection demonstration area and normalizing the use of drone inspections [4]. - The evolution of drone inspections has progressed from manual control (1.0) to autonomous inspections (2.0) and finally to collaborative drone nests (3.0), marking a significant transformation in the industry [4].
