摘要
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。
Compared to laser rangefinder and infrared range,ultrasonic ranging is more close to civilian life,low cost,simple operation,wide application range,high precision at close range.This paper introduces the principle of ultrasonic distance measurement and how to control it,and ranging with the use of SCM and broadcast real-time and frequently asked questions in debugging process.
