Abstract: By configuring high-definition cameras, robots, drones and other types of intelligent inspection equipment in substations for inspection data collection, the coverage of intelligent inspection points in substations, system connectivity and image recognition rate are improved, and a joint inspection system for substations is built to solve the problem. Manual inspections have problems such as insufficient personnel, low inspection efficiency, and blind spots in inspections, etc. The intelligent joint inspection system can improve the intelligent and digital level of equipment inspections.
