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,从而设计了一套超声波检测系统。对系统硬件组成、检测原理、方法以及系统软件结构作了详细介绍,对产生测量误差的原因进行了分析,并提出了解决的途径和方法。
In this paper,according to the principle of ultrasonic transmission in the air,a suit of practical ultrasonic measuring system is designed by using the technique of Single Chip Microco(SCM) and the ultrasonic transducer. The units of the system and the principle and ways of measuring are described in detail. The reasons for the measuring errors are also analyzed,and the solving means offered.
