With the widespread application of intelligent unmanned units and the development of wireless energy transmission technology, it has become an urgent requirement in the field of using wireless power transmission to extend the continuous working time of unmanned units. To improve the wireless transmission energy efficiency in practical application as much as possible based on the current development level of wireless transmission technology, this paper first enumerates and analyzes existing wireless energy supply methods and shows that microwave wireless energy transmission technology is most suitable in this study. Then, the necessity of power transmission relay in long-distance microwave wireless power transmission is discussed. Based on the idea of microwave energy relay transmission, the paper constructs a microwave wireless transmission link planning model which considers power relay and uses the evolutionary algorithm to solve the wireless transmission link planning model with two-layer optimization. Finally, the results show that, when the wireless transmission distance exceeds a certain threshold, adding relay nodes to the link can improve the energy transmission efficiency from the power supply node to the power receiving node.

考虑微波能量中继的无线能量传输链路优化

随着智能无人机的广泛应用和无线能量传输技术的发展，延长无线无人机的连续工作时间已成为迫切需要的领域。基于当前无线传输技术的发展水平，为尽可能提高实际应用中的无线传输能量效率，本文首先对现有的无线能量供应方法进行了列举和分析，表明微波无线能量传输技术最适合本研究。 。然后，讨论了远距离微波无线电力传输中功率传输中继的必要性。基于微波能量中继传输的思想，本文构建了一个考虑功率继电器的微波无线传输链路规划模型，并采用进化算法对无线传输链路规划模型进行了两层优化。最终，结果表明，当无线传输距离超过一定阈值时，在链路上增加中继节点可以提高从供电节点到受电节点的能量传输效率。
