Abstract: By analyzing the problems existing in route selection of intelligent inspection robot in substation, the route of intelligent inspection robot is improved. So that it can quickly find the optimal path and reach the target equipment to collect various information in the emergency state of the accident. Make use of the cable cover route in the existing substation or add a suitable route to enrich the route selection of intelligent inspection robot. When it is on standby in the robot room or receives instructions related to accident emergency treatment during the execution of command tasks, it can select the best route nearby and quickly rush to the target equipment to perform tasks.
