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 ...

Abstract

The invention discloses an air wireless energy transfer system adopting unmanned aerial vehicles, and belongs to the technical field of new-generation air traffic and renewable energy utilization. Anenergy charging framework of unmanned aerial vehicles (UAVs) with a no-stopping characteristic is designed in the system, and an air charging platform framework is realized. The framework comprises aground radio transmission array consisting of a charging coil and an air unmanned aerial vehicles (P-UAVs) located inside the effective radiation angle of the array, and also relates to an intelligentinformation processing and control mechanism related to machine learning. For the UAVs to be charged, the P-UAVs can be used for positioning and tracking the UAVs actively, and wireless energy transfer can be carried out on the P-UAVs, so that the coverage range of an original wireless energy transfer device is expanded. According to the system, the omni-directional coverage range of the ground wireless charging array is expanded, and the deployment quantity of ground charging array equipment is reduced, so that the deployment cost is reduced; and through the no-stopping characteristic, the energy charging and traffic operation efficiency in air traffic is also improved.

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...
