The invention discloses a power transmission line external force damage intelligent identification method based on an intelligent sensing terminal. The method is reasonable in step and convenient to operate stably. The sensing terminal is connected with a corresponding network data aggregation server, a plurality of network data aggregation nodes, a branch box monitoring unit, a meter box monitoring unit, a user power supply monitoring module box body, an internal storage battery, a power supply management board, an ARM image processing board, an infrared analog camera, a digital camera, a GPSmodule and a solar cell panel arranged outside the box body, a target recognition machine, a server and a mobile phone mobile terminal comprising a 4G module, the infrared analog camera is connectedwith the ARM image processing board and is used for acquiring image data of a power transmission line and sending the acquired image to the target recognition machine through the 4G module; The methodis reasonable in step and stable in effect, and the tedious step of manually selecting features is liberated; the method is high in dangerous operation target recognition rate, is high in recognitionrate, and can guarantee the real-time requirements.
