摘　　要：给出一个红外光数字通信实验系统的设计,系统以超低功耗MSP430F149单片机作为控制核心,以温度数字信号作为信源,实现短距离红外光传输数字信号。系统包含3个主要部分,分别为发射终端、接收终端和中继转发节点。经测试,数字温度信号直接传送距离超过5米,中继距离亦可达到5米以上。A design of experimental system of infrared digital communication is given,which is based on the ultra- low power MSP430F149 microcontroller,and the system is able to realize short- range wireless transmission of digital signals. The system consists of three main parts,namely the transmitting terminal,receiving terminal and relaying nodes. In this experiment digital signals can be directly sent over 5 meters and the relay distance also reach more than 5 meters.
