The electric power intelligent inspection robot is equipped with high-definition visible light camera, infrared thermal imager, sound-collecting equipment and other intelligent detection devices and intelligent analysis algorithm software to complete the control loop of all-weather data rapid acquisition, real-time information transmission, intelligent analysis and early warning to fast decision feedback. Therefore, instead of manual inspection, the automatic detection and intelligent analysis of the state of the power equipment are realized, and the reliability of the operation of the power grid and the power equipment is improved. The use of electric power intelligent inspection robots is an important means to realize the intelligentization of power grids, and is an important direction for the future development of smart grids. In view of the current research status and deficiencies at home and abroad, this paper discusses the main technologies, cutting-edge technology, functional positioning and standard system of electric power intelligent inspection robots, and discusses the research status of electric intelligent inspection robots. On this basis, the future research and development direction are proposed. This paper has a guiding role and reference value for the research of electric power intelligent inspection robot.
