摘要
介绍一种便携式的红外测距系统。为了实现物体近距离、高精度的无线测量,采用红外发射接收模块作为距离传感器,单片机作为处理器,编写A/D转换、显示以及与PC机的通信程序,开发了一套便携式的红外距离测量系统,系统可以高精度的实时显示所测的距离,并且可以将距离量通过串口发送到PC机显示处理。本系统结构简单可靠、体积小、测量精度高、方便使用,另外本系统形成了一套完善的软硬件开发平台,可以进行扩展、移植和做进一步的开发。
This paper introduces a kind of portable infrared distance system. In order to measure the near objects wirelessly and precisely,we used the infrared emission and accept module as sensor, MCU as processor,wrote A/D conversion, data display and communication programs, created a portable infrared distance measure system.This system can display the distance precisely and constantly ,and can transfer the distance data to PC through serial port.The characteristic of the system is simple, reliable,small, precise and easy to use,the system is also a open platform,which contains hardware and software, and it can be expanded, transplanted and upgraded conveniently.
