一种使用红外线和超声波的定位技术

本文提出了一种使用红外线和超声波的定位技术,对其工作原理和主要部分的实现方法进行了介绍,设计了测量脉冲调理电路接收超声信号,并分析了主要的误差源。该技术使用红外编码指令触发定位,扩大了定位范围,降低了功耗;在接收电路中加入共振电路,减小了外界干扰。通过大量实验,分析了环境温度、传播角度等因素对测距精度的影响。

Positioning technique with infrared and ultrasonic

A positioning technique with infrared and ultrasonic is presented.The work principle and the techniques of the principal parts are introduced.A measuring pulse adjusting circuit is designed to receive the ultrasonic and the errors are analyzed.This technique uses infrared coding command to trigger the positioning,extending the positioning rang and reducing the power,and adds a syntonic circuit to the receiver to reduce the disturbing.The effecting factors of precision such as temperature and angle are analyzed according to lots of experiments.
