Study on Induction-based Energy Harvesting of Drones Utilizing Electromagnetic Radiation of Transmission Lines
Drones are regarded as the best choice for electric inspection.However,due to the inadequate battery energy density,drones'normal working ability is largely limited.By adopting radio energy transmission technology,endurance and inspection range of drones can be significantly improved.In this paper,the drone charging technologies are compara-tively studied,and the coupling mechanism is optimized and improved aiming at high efficiency and stability.Based on the vortex induction principle,a drone charging scheme with the coil structure of the cross-type magnetic field coupling mech-anism is proposed.The autonomous charging program is described in detail.Finally,the miniaturized experimental plat-form is used to verify feasibility and practicability of the proposed drone charging scheme.
