Embodiment Construction

[0025] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0026] The energy conversion method of the present invention uses solar energy as the power supply energy for wireless charging, and the wireless charging platform gets rid of the limitation of needing a fixed power supply, making it more portable, combined with the array-type micro-battery of the drone, the charging efficiency is higher, and the charging time is shorter. greatly shortened. When the UAV is working outdoors, the platform can charge the UAV and its battery in time when there is sufficient sunlight. More portable. The hardware used in the present invention includes two parts, one is an energy conversion platform, and the other is a wireless rechargeable battery of the drone placed in the drone.

[0027] The solar powered UAV energy conversion platform adopted by the present invention includes: a solar power storage module, a wireless charging tr...

Abstract

The invention relates to a method for energy conversion of a solar-powered unmanned aerial vehicle. An adopted device includes an energy conversion platform and an unmanned aerial vehicle battery placed in an unmanned aerial vehicle. The method for energy conversion includes the steps that a photovoltaic cell panel receives solar energy and charges a battery pack, and a controller protects the battery pack from overcharge and overdischarge; when the unmanned aerial vehicle hovers over the platform and starts charging, a transmitting terminal communication module starts charging and controls apower supply voltage after receiving a receiving voltage request from a receiving terminal; a transmitting terminal wireless charging module reverses the direct current voltage to an alternating current, energy exchange is achieved through a transmitting terminal coil, and a high-frequency electromagnetic field is generated; during charging, the communication with a receiving terminal communication module is maintained; the receiving terminal communication module monitors a receiving voltage and feeds the receiving voltage back to the transmitting terminal communication module, and a transmitting voltage is adjusted and maintained at a safe charge voltage.

Description

technical field [0001] The invention relates to an energy conversion method for an unmanned aerial vehicle powered by solar energy. Background technique [0002] In recent years, UAVs have become more and more widely used in aerial photography, logistics, agriculture and other fields. However, an important reason that restricts the large-scale use of drones is the battery life of drones. Wired charging of drones not only requires repeated plugging and unplugging, resulting in battery damage, but also when the drone is working in a dangerous environment, the electric sparks generated by wired charging will cause more problems. It seems that wireless charging is the best option to improve the drone's endurance. With the development of wireless charging technology, the technology of wireless charging through electromagnetic induction has gradually appeared, but the current wireless charging technology is not perfect enough, and the problems of low charging efficiency and slow...
