Design of a device mounted on unmanned aerial vehicle for high-voltage power line inspection with image acquisition and recognition

In the maintenance and operation of power systems, it is crucial to detect foreign objects hanging on transmission lines, especially for high-voltage overhead transmission lines. A device mounted on unmanned aerial vehicle for high-voltage inspection drone loading device was designed, using the YOLOv5 (You only look once version 5) algorithm with a self-constructed foreign object data set to train the model, and combining various sensors, to achieve timely and effective detection of foreign objects on high-voltage transmission lines or high-voltage transmission towers. The feasibility of this design was validated through model testing. The device connects to the unmanned aerial vehicle via a type-C interface as an external load, ensuring no safety hazards and expanding the application scope of the unmanned aerial vehicle with minimal hardware requirements.
