| 摘 要： | 以测量超声波发射与反射时间差作为测距的基本原理,设计并实现可自动测距系统.将系统分为超声波发射、超声波接收、计时电路等若干部分,分别进行设计,并进行适当优化.每一部分均使用Multisim软件进行仿真及验证.相比以往的测距电路,本系统不仅能给出测出的距离,还增加了报警系统的设计.实验结果表明,本系统具有稳定、灵敏度强、测量精度高的特点,并具备一定的应用和推广价值.

| Abstract: | The basic theory in designing and implementing the ultrasonic distance measuring system,is to record the time between the emission wave and the reflected wave by the object.The system is divided into ultrasonic wave emission,wave reception and time counting parts,which are designed and optimized respectively.Every part is simulated by using the Multisim simulation software.Compared with the traditional implementation,this system,not only have the function of measuring the distance but also have the alarm sy... |
