AI Technical Summary

Problems solved by technology

On the one hand, due to the actual circuit load operation, there are certain safety hazards in the multi-rotor UAV performance test. The higher the voltage level, the greater the risk

On the other hand, the actual line voltage level cannot be adjusted, and there are certain limitations in the electromagnetic compatibility performance test of multi-rotor drones

At the same time, there are contingencies and uncertainties in the location of defects in overhead transmission lines. It is impossible to simulate typical defects in actual overhead lines, and it is difficult to conduct targeted tests on the performance of multi-rotor UAVs.

Finally, during the performance test of the multi-rotor UAV, the actual overhead transmission line is not equipped with corresponding auxiliary sensors, considering the flight height and parallax, resulting in subjective judgment of the accuracy of the performance test
