摘要：
This paper introduces the design process of ultrasonic transmitting and receiving device. The designed circuit of DC/DC high voltage power supply's control chip is TL494, provide a voltage 260V DC. The transmitting and receiving circuits are based on the control of single chip computer. and generate high voltage pulsed by the theory of capacitor discharge. The wide-range dynamic echo signal is amplified by the circuit of logarithmic amplifier. and processed by the software resources on the PC. The experimental results show that the circuit completed works well and stable.
