摘要
根据声波在空气中传播反射原理,以超声波换能器为接口部件,应用单片机技术对超声波在空气中的传播时间进行测量,设计了超声波检测系统。详细介绍系统硬件组成、检测原理、方法以及系统软件结构。
In this paper, according to the principle of ultrasonic tran-smission in the air, a suit of practical ultrasonic measuring system is designed by using the technique of single chip microco （ SCM ） and the ultrasonic tran-sducer. The units of the system and the principle and ways of measuring are described in detail.
