The traditional system that uses shortwave transmitter to adjust the working frequency of radio power transmission is susceptible to external signal interference,resulting in low tuning accuracy. In order to solve this problem,an anti interference tuning system is designed. The Zedboard extension processing platform is used as research and development board to design the overall scheme of the system. Zynq7020 is utilized to study the hardware structure of the system. The anti jamming tuner is designed by using DSP chip of TMS320VC5416PCE. The A/D conversion is used to filter the jamming signal before frequency mixing. Signal oscillation and tuning circuit are designed to obtain the amplitude and phase of voltage and current signals,and provide data for system tuning. The working frequency of the receiver and transmitter is analyzed according to the system software design process. The configuration parameters are changed according to the digital signal processing sequence diagram to adapt to different hardware to ensure the anti interference ability of the system tuning. The experimental results show that the system has high tuning accuracy and lays a foundation for efficient transmission of radio energy.
