Design and implementation of intelligent ultrasound and intermediate frequency therapeutic instrument based on FPGA control
Ultrasound and modulated intermediate frequency current act on human body together,which is a new combination of electroacoustic therapy.In this system,the most popular STM32 series chip STM32F103ZET6 is used as the main control chip,and the more flexible and efficient FPGA technology is used as the DDS signal generator,the 12-bit high-speed DA converter and the high-voltage high-speed amplifier for primary amplification,and then impedance matching is performed.By sampling the power supply current of the amplifier,the working state of the ultrasonic transducer is judged,and it is connected to the ultrasonic transducer and the intermediate frequency electrode,so as to achieve the efficient and stable work of the wholesystem.
