摘要
超声波测距是一种有效的非接触式测距方法。文中分析研究了超声波测距的原理,设计了一款基于单片机AT89S52的带有温度补偿和显示报警功能的超声波测距系统,并对该系统的硬件组成和软件控制流程中的关键点进行了详细阐述。最后还对系统的测量范围、精度和可靠性等进行了测试,分析了误差产生的原因,并对系统的完善提出了一些改进建议。
Ultrasonic Ranging is an effective method for non-contact distance measurement.This paper analyzes the principle of ultrasonic ranging,designs an ultrasound ranging system with temperature compensation and alarm function based on single-chip microcomputer AT89S52,and describes the key points in the hardware and software of the system in detail.Finally,it tests the measurement range,accuracy and reliability of the system and proposes some suggestions for improvements of the system.
