摘要
红外遥控技术在家电、智能仪器、工业控制方面应用广泛 ,本文从遥控的发射和接收两个方面详细介绍了红外遥控信号的编码、调制、发射 ,接收、解调、解码的原理、分类及其实现方法 ,指出了各自的应用场合 ,并给出了应用建议。针对三种不同的编码方式 ( FM、PWM、PPM) ,给出了相应的软件解码的流程图。
Infrared remote control was widely used in intelligent instrument,industry control.In this paper, the principles of coding,modulation, transmittal,receiving, demodulation was discussed in detail.The class of infrared control and the situations in which infrared remote control used were described,and suggestions on application were given. At the end of this paper, the flow charts of three kinds of decoding were described also.
