Design Of Power Line Inspection With Unmanned Aerial Vehicles Command System Based On GPS Navigation

220kV and above voltage level of high voltage transmission line, usually aftermountains, forests and lakes and other traditional manual operation need to spend a lot oftime, can’t even areas of inspection, inspection efficiency, observe the effect and theoperation safety can not be guaranteed, while the use of unmanned aerial vehicle (UAV)on the transmission line inspection of transmission lines are efficient, non-contactinspection work, can improve the inspection quality, and ensure the safety of operators onthe inspection.UAV patrol the area are mostly low-altitude areas of the complex, topography andclimate environment is complex and changeable, power towers, and transmission lines,trees, buildings, etc. barriers exist, job site also limits the UAV can not always a safelanding. Rotor machine of take-off and landing site without special requirements, to hoverin the air operation, small turning flight radian, so the rotor unmanned aerial vehicle (UAV)of transmission lines to conduct a detailed inspection. The four rotor UAV due to the rangeand their own performance constraints, only the transmission line tower and tower linenear the patrol line.Transmission line structure is more compact, inspection operations more goals, inorder to make the UAV in the inspection process not the transmission line safe impact andimprove without man-machine patrol line efficiency, need according to the UAV ControlPlanning of UAV patrol route and route optimization. In the optimization process, give fullconsideration to the actual patrol line without man-machine air flight angle, threatconstraints and energy consumption in factors, and the ant colony algorithm is applied inthe transmission line without unmanned aerial vehicle inspection path planning, pathoptimization can effectively improve the quality inspection and the inspection efficiency.Based on this article summarizes the theoretical foundation of the tower inspectionprocesses and inspection paths, analyzes the function of the system, designed UAV patrolline of command. Through the pre-job preparation, determine the inspection operation transmission line segment and the inspection target, realize the inspection workenvironment generation. The ant colony algorithm used to optimize the inspection path,the optimal path of inspection operations. Based on GPS navigation technology, functionsof realized automatic inspection operation and real-time track coordinate display functionswere realized completely. Through the wireless communication module, realize the videoreceiving and display inspection. Patrol captured images to achieve fault analysis anddiagnosis by image processing. Inspection process ends, to achieve the scanning taskinformation storage and printing.By UAV patrol line command to test the system, the system can work in accordancewith the UAV inspection process, the inspection work to determine for target drones on theline in accordance with the optimized route inspections, the chain of command for theUAV inspection tasks detailed records, complete transmission line inspection work. Theapplication of the patrol command system can improve the inspection efficiency and effect,and can further reduce the difficulty of manual fault identification.
