As the use of manual inspection of the power system is time-consuming and laborious, the use of UAV to patrol the power system also arises at the historic moment. However, the UAV inspection system is easy to deviate from the preset route due to electromagnetic interference, which is easy to cause accidents caused by the decrease of maneuverability. In this paper, an obstacle avoidance system based on electromagnetic sensor and visual distance measurement is designed. in the process of running the system, electromagnetic sensor and vision module are used to collect electric field signal and video signal. Through the signal processing module to complete the corresponding filtering, amplification, analog-to-digital conversion and other operations, to obtain accurate obstacle avoidance information, relying on the electric UAV flight control to complete the corresponding obstacle avoidance judgment and attitude 2conversion. Through the simulation experiment, we can know that after the introduction of the UAV, the electric field strength of the UAV increases by about 85%, but it is still much lower than the breakdown voltage. The threat can be ignored and the patrol task can be well completed.
