Embodiment Construction
[0016] The invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] The present invention performs proxy transmission of radio energy by deploying mobile P-UAVs in the coverage area of the ground wireless energy transfer array, and processes intelligent information in the field of machine learning, such as classification and prediction mechanisms based on Bayesian decision-making for target UAVs. Flight trajectories and velocities are predicted to assume the role of energy transfer agents as target UAVs approach and fly out of the coverage area of ground-based radio transmitter arrays. It can expand the size of the wireless energy transfer coverage area in all directions, and effectively solve the unevenness of the spatial distribution of the energy transfer effect. see figure 1 , for the area 2 outside the area 1, the electromagnetic wave radiation power density has spatial distribution inhomogeneity. Therefore, if the ...

The invention discloses an aerial wireless energy transmission system using an unmanned aerial vehicle as an agent, and belongs to the technical field of new generation air traffic and renewable energy utilization. The system designs an energy charging architecture for unmanned aerial vehicles (UAVs) with the characteristics of no-docking, and realizes the architecture of an aerial charging platform. The architecture consists of a ground-based radio transmission array consisting of charging coils and aerial unmanned aerial vehicle agents (P‑UAVs) within the effective radiation angle of the array. It also involves intelligent information processing and control mechanisms related to machine learning. For UAVs to be charged, P-UAVs can actively locate and track UAVs and perform wireless energy transfer on them, thereby extending the coverage of the original wireless energy transfer device. The invention expands the omnidirectional coverage of the ground wireless charging array, reduces the deployment quantity of the ground charging array equipment, thereby reducing the deployment cost; the non-stop feature also improves the efficiency of energy charging and traffic operation in air traffic.
Description
technical field [0001] The invention relates to an aerial wireless energy transmission system using an unmanned aerial vehicle as an agent, and belongs to the technical field of air traffic and renewable energy utilization. Background technique [0002] In recent years, wireless energy transfer technology has been widely used in scientific research and industrial production, especially in wireless charging systems for mobile devices such as drones and unmanned vehicles. Specifically, wireless energy transfer refers to the direct transmission of energy through radio without using facilities such as cables or wires when performing energy transmission on electrical equipment. This energy transmission method can maintain the flexibility of the equipment to the greatest extent, and reduce the limitation of the energy transmission medium on the physical location of the equipment, especially for equipment that often needs to be moved. Many related research literatures have reporte...
