AI Technical Summary
In existing wireless charging systems for drones, there is a problem of low docking accuracy between the drone and the host aircraft in the air, making it difficult to achieve stable and reliable autonomous docking and energy transfer in the air.
A three-level guidance and docking strategy is adopted, including first-level guidance based on satellite navigation, second-level guidance based on visual images, and third-level guidance based on magnetic attraction mechanism. Combined with electric field coupling wireless charging module, a chain power transmission network consisting of fixed charging base station, hovering mother machine and working daughter machine is constructed to realize the autonomous docking of UAV in the air.
It enables fully autonomous, high-precision, and lightweight charging of drones in the air, expanding the operational range and time, improving docking accuracy and reliability, reducing mechanical wear, extending the service life of drones, and lowering maintenance costs.
