Abstract

The invention is suitable for the field of energy distribution technology improvement, provides a laser energy supply unmanned aerial vehicle trajectory optimization and communication power energy distribution method. The energy distribution method comprises the following steps that S1, an unmanned aerial vehicle flies n1 circle around the circuit taking r1 as the radius above a laser source to obtain the enough net energy; S2, the unmanned aerial vehicle flies along the l1l2 tangent line after obtaining the enough net energy; S3, the unmanned aerial vehicle flies n2 circle around the circuittaking r2 as the radius on a sensor to transmit information to the sensor. The double-circle trajectory is selected as an initial trajectory, the optimal unmanned aerial vehicle trajectory and the optimal power distribution on the trajectory are obtained through an algorithm 1 to maximize the throughput, and the throughput can be improved after each iteration. The method is simple and clear, the cruising ability of the unmanned aerial vehicle is effectively prolonged, and the trajectory and the transmission power are reasonably optimized, the throughput of the channel is maximized, and the communication performance of the unmanned aerial vehicle is effectively improved.

Description

technical field [0001] The invention belongs to the field of energy distribution technology improvement, in particular to an energy distribution method for trajectory optimization and communication power of a laser-powered unmanned aerial vehicle. Background technique [0002] The drone transmits data to ground sensors. However, the endurance of drones is limited. Wireless charging can provide longer usage time for energy-constrained devices. In order to improve the endurance of the UAV, we assume that there is a UAV powered by laser beam charging in the system. Such as figure 1 Shown: During the flight energy consumption process of the UAV, it needs to obtain energy from the laser beam emitted by the laser source, and at the same time use the received energy to power the ground sensors to support the information transmission between them. Due to the maneuverability of the UAV, the energy harvested by the UAV and the rate at which information is received by ground sensor...
