具有语音播报的测距仪的设计

摘要

Compared to Iaser rangefinder and infrared range,uItrasonic ranging is more cIose to civiIian Iife,Iow cost,simpIe operation,wide appIication range,high precision at cIose range.This paper introduces the principIe of uItrasonic distance measurement and how to controI it,and ranging with the use of SCM and broadcast reaI-time and frequentIy asked ques-tions in debugging process.%超声波测距相比较于激光测距和红外测距，更为贴近于生活民用，成本低，操作简单，适用范围广，在近距离内精度较高。介绍超声波测距的原理及控制方式，并使用单片机实现测距同时进行实时的语音播报的实现方式及调试过程中的常见问题。
