The research and application of the visualized anti external damage intelligent inspection system for transmission lines aims to actively detect, capture, and warn construction vehicles, personnel, and super tall trees in the transmission line corridor. At the same time, the monitored external force damage video image information is transmitted to the background monitoring platform through 3G/GPRS/CDMA network, which can systematically solve the problem of standardized operation on inspection sites and provide support for lean management of transmission lines.
