Abstract:In order to solve the substation indoor artificial inspection way, low efficiency, high cost and low accuracy of inspection, to better promote the development of digital and intelligent power grid, this paper designed a set of robot system is suitable for indoor substation inspection operations and inspection robot the robot system includes terminal and private network, database, remote management of terminal four parts, At the same time, the indoor positioning algorithm of the robot is studied, the hardware structure of the robot is designed, the control system of the robot is developed, and the positioning accuracy, reliability and safety of the robot are simulated and field operation experiments. The experimental results show that the inspection robot designed in this paper can well adapt to the substation indoor environment, and the robot can achieve accurate positioning and navigation, accurate inspection and fault warning of substation indoor equipment operation, and meet the requirements of substation indoor inspection. Finally, this paper summarizes the research work and puts forward the next research plan.
