Description

technical field [0001] The invention relates to the technical field of UAV safety protection, in particular to a UAV strong electromagnetic pulse protection system and an experimental method thereof. Background technique [0002] With the maturity of drone technology, the application range of drones is getting wider and wider, and the flying environment of drones is becoming more and more complex. Most of the existing drones have a general electromagnetic interference protection design, such as using shielded wires, installing flow guide strips, and processing holes, etc. These measures can ensure the flight safety of drones in general electromagnetic interference, but for strong Electromagnetic pulse interference, such as lightning electromagnetic pulse, weapon-grade electromagnetic pulse, and electromagnetic pulse generated by UHV power grid, etc., is difficult to achieve high-level protection. For example, in "Electromagnetic Protection Technology for UAVs in Strong Elec...

AI Technical Summary

Problems solved by technology

[0003] The existing EMP protection schemes for UAVs are mainly system-level rectification suggestions, which cannot effectively deal with the interference of strong EMP

For example, in UHV line inspection operations, the current drones can only maintain a relatively long flight safety distance, which is not conducive to the accuracy of line inspection observation, and the line inspection efficiency is low

And there are higher requirements for the shooting lens, resulting in higher solution costs

In uncontrollable situations, such as lightning electromagnetic pulse interference, it is likely to directly cause a crash, which increases the damage cost of the drone
