Embodiment Construction

[0047] Such as figure 1 As shown, the flow chart of the optimization method based on the wireless information and energy transmission of the unmanned aerial vehicle provided by the present invention is described in detail as follows:

[0048] System Model Description

[0049] Consider the UAV-based downlink wireless information and energy transmission system. In this system, both the UAV and the wireless device have batteries. When the UAV transmits energy to the wireless device, the wireless device stores the energy in its own In the battery; when the drone transmits information to the wireless device, the wireless device uses the energy of the battery to receive the signal of the drone and decode it.

[0050] Such as figure 2 As shown, the model includes a drone and multiple wireless devices. Due to the limited energy of the UAV, in order to save energy, it only makes height adjustments and does not make horizontal displacements during the entire working time. The UAV a...

Abstract

The present invention is applicable to the improvement field of energy balance distribution technology, and provides an optimization method for wireless information and energy transmission based on unmanned aerial vehicles, including the following steps: S1, the wireless device reports its own energy state to the unmanned aerial vehicle; S2, wireless The man-machine detects the channel state between itself and the wireless device; S3, the UAV selects the optimal action based on the estimated revenue maximization according to its own power, the power of the wireless device and the channel state. The use of wireless devices can save wiring costs, beautify space, small size and low power, apply drones to wireless device information and energy transmission, and improve network data transmission rate and energy conversion efficiency.

Description

technical field [0001] The invention belongs to the field of energy balance distribution technology improvement, in particular to an optimization method for wireless information and energy transmission based on drones Background technique [0002] Unmanned aircraft, referred to as UAV, is an unmanned aircraft that uses wireless remote control, and can also be programmed to achieve automatic flight. In recent years, the related technologies of drones have become more and more mature, playing an important role in the fields of wireless communication and wireless charging. The reason why UAVs can play an important role in the field of wireless communication and wireless charging is that it is flexible and can be conveniently placed wherever it is needed, and because it is close to the communication target, it can obtain a better communication environment, thereby Improve data transfer rate and energy transfer efficiency. [0003] In my country, with the popularization of the ...
