In order to solve the problem of high leakage rate in the existing automatic control system of electric power inspection robot, the automatic system of electric power inspection robot was proposed. The hardware design of the automatic control system of the power inspection robot is embedded Linux design, motor driver design and infrared thermal image thermometer design; The software design includes motor driver initialization, motion control programming, interrupt positioning and calibration programming. Through the design of system hardware and software, the operation of the automatic control system of power inspection robot based on embedded Linux is realized. The experimental results show that the leak detection rate of the designed system is far lower than that of the existing system, and its minimum value can reach 10.25%.
