超声波收发及电子开关电路的设计

Study of Ultrasonic Transceiver and Electronic Switching Circuit

超声波在金属测厚中有广泛的应用,本文设计了一种超声波收发及电子开关电路,该电路经分析及实验证明在超声波测厚时可以较好完成超声波信号的激励,能够完成信号收发,为超声波测厚奠定基础.

The ultrasonic finds wide application in determination of the metal thickness, a ultrasonic transceiver and electronic switch circuit is thus designed to this end. The circuit analysis and experiment show that it does a good job in fulfilling the task of ultrasonic stimulation in the process of thickness measurement and is capable of sending and receiving ultrasonic sig- nals, so it lays a foundation for ultrasonic thickness measurement.
