“Against the backdrop of energy transition and frequent extreme weather disasters, the operation and inspection of transmission lines are facing challenges. By creating a new operation and maintenance model of "three-dimensional inspection+centralized monitoring", we can solve the current difficulties and build a three-dimensional inspection system that integrates "sky, air, line, and person". By using technologies such as satellite remote sensing, drones, and robots, we can achieve comprehensive monitoring of transmission lines; Strengthen the construction of centralized monitoring system, deploy visualization devices on a large scale, integrate intelligent operation and inspection systems, and enhance operation and maintenance control capabilities; Utilize technological means to enhance the level of intelligent maintenance operations.”
