摘　　要：为解决航空发动机旋转部件热力参数测试中系统供电与信号传输的问题,提出了一种通过共享通道实现能量与信号同步传输的方法。采用串并联复合谐振网络。在无线能量传输的基础上,引入信号回路。通过单一耦合通道实现能量的正向传输和信号的反向传输。通过理论计算对系统精确建模,并使用MATLAB/Simulink软件进行系统仿真,并根据仿真参数建立了实物平台。结果表明:在能量传输频率300 kHz,信号载波频率为2.8 MHz的情况下,实现了13.03 W的功率输出以及80 kbps的反向信号传输。验证了传输方法的可行性。To address the power supply and signal transmission challenges in the thermal parameter testing of rotating components in aviation engines,a method for synchronous energy and signal transmission through a shared channel is proposed.The approach utilizes a series-parallel composite resonant network.Building upon wireless energy transfer,a signal loop is introduced.Energy is transmitted in the forward direction,and signals are transmitted in the reverse direction through a single coupling channel.The system is accurately modeled through theoretical calculations,and MATLAB/Simulink software is employed for system simulation.A physical platform is established based on simulation parameters.The results show that a power output of 13.03 W and a reverse signal transmission of 80 kbps are realized at an energy transmission frequency of 300 kHz and a signal carrier frequency frequency of 2.8 MHz.The feasibility of the transmission method is verified.
