超声波测距系统的设计与研究

介绍的超声波测距系统,采用渡越时间法实现了空气测距目的。该系统以单片机作为核心控制器,控制超声波的发射和接收,记录超声波由发射到反射所经历的时间,最终计算出距离,并显示。系统软硬件均采用模块化设计,硬件电路结构简单,多采用集成芯片,减少了电路间干扰,便于调试。该测距系统通用性强,可用于倒车雷达、物体位置测量等场合。

The design and study of the ultrasonic ranging system

The paper introduces the ultrasonic ranging system, air using the time of flight. The singlechip as the core which achieved the aim of ranging in the controller controls the ultrasonic waves＇ transmitting and receiving, records the time of flight, calculates distance finally, and shows distance. The software and hardware in this system are designed based on modularizationo The hardware is single and uses the more integrated chip. So the circuit reduces interference. And the debugging is also easy. This ranging system has the more strong generality and is capable of parking distance control and measuring position object and so on.
