The invention relates to an intelligent inspection method for a transmission line. According to the intelligent inspection method, a GPS collects position coordinates of towers on the transmission line, an inspector carries intelligent mobile equipment to arrive at an inspection point under the guidance of navigation, inspection data is sent to a monitoring background through a wireless network, a GIS is utilized to display a movement track of the intelligent mobile equipment on an electronic map, and monitoring of an inspection route and an inspection state is completed. Through the method, automatic detection and positioning of a line fault are realized, line inspection time is saved, and working efficiency is greatly improved. The method is used for solving the problems that existing line inspection methods are low in working efficiency and high in cost.
