Emergency wireless charging system based on tethered unmanned aerial vehicle

Abstract

The invention relates to an emergency wireless charging system based on a tethered unmanned aerial vehicle. The emergency wireless charging system comprises a tethered unmanned aerial vehicle aircraft, a launcher underprop and a receiver; the launcher underprop is arranged on the tethered unmanned aerial vehicle aircraft and comprises a underprop controller, a pumping module, an optical charging transmitter and a first communication device; the receiver comprises a second communication device and further comprises a charging receiver, an electric energy converter and a load which are sequentially connected, and the first communication device is in communication connection with the second communication device; and the optical charging transmitter is pumped through the pumping module and subjected to energy supplying by a ground base station through a communication / power supply cable, and then emits a resonant optical beam to transmit power energy to an optical charging receiver. Compared with the prior art, 0-50 m of remote emergency wireless charging is achieved through the tethered unmanned aerial vehicle, real-time adaptive tracking and alignment of the launcher underprop to thereceiver is further achieved, movable charging of the receiver is ensured in the unmanned aerial vehicle coverage range, and the emergency wireless charging system can work in day and night scenes.

Description

technical field [0001] The invention relates to the field of long-distance wireless energy transmission, in particular to an emergency wireless charging system based on a tethered drone. Background technique [0002] The technical concept of the tethered UAV comes from the tethered balloon launch platform system. A typical tethered balloon system is manufactured by a well-known American manufacturer, TCOM. It serves as a space-based platform for fixed-point monitoring of electronic equipment. At present, the maritime warning radar network on the west coast of the United States is deployed by TCOM tethered balloons as air-based platforms. However, the tethered balloon system is bulky and difficult to lift, and its mobility and adaptability are poor. With the rapid development of multi-rotor UAV technology, and in order to solve the inherent problems of the above-mentioned tethered balloon system, many UAV manufacturers have launched the research and development of tethered ...

AI Technical Summary

Problems solved by technology

However, in the tethered UAV wireless charging scenario, due to the limited field of view of the optical resonance wireless charging technology, it is difficult to realize the large-scale mobile tracking and charging of electronic devices.

In addition, the high-altitude gimbal of the untethered UAV cannot provide the required energy for the transmitter of the optical resonance wireless charging system.
