摘要
红外无线PPM(脉冲位置调制)通信技术是以红外线作为通信载体,采用PPM调制技术以实现室内红外无线局域网通信的技术。根据PPM的特点,采用单片机控制的方法来实现PPM发射机的设计,大大简化了硬件电路。介绍了硬件电路原理和单片机的软件设计方法,并通过实验完成了PPM光信号的发送,收到了满意的效果。
Wireless infrared pulse position modulation (PPM) communication uses infrared as the communication carrier and adopts PPM technology to realize the communication in indoor wireless infrared local network. According to the characteristic of PPM, this paper uses MCU to realize the design of PPM transmitter, thus greatly simplifying the hardware circuit. The principle of hardware circuit and the program of MCU are introduced and the transmission of optical PPM signal is accomplished through the test, acquiring a satisfied result.
