Wireless Energy and Signal Simultaneous Transmission Method Based on Composite Resonance
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 uti-lizes 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 trans-mission 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.
