脉冲位置调制(PPM)具有功率利用率高的优点,在室内红外无线局域网中得到广泛的应用。利用AT89S52型单片机和编程软件Visual C++设计了一种基于计算机串口的红外无线PPM发射机,介绍其硬件电路原理及计算机和单片机的软件设计方法。实现了PPM光脉冲的发送。
Pulse position modulation (PPM) with the advantages of high power utilization, indoor infrared wireless LAN has been widely used. Using AT89S52 type MCU and programming software Visual C ++, we designed a kind of infrared wireless PPM transmitter based on computer serial port, introduced the principle of its hardware circuit and the software design method of computer and SCM. PPM optical pulse transmission.
