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.
