摘　　要：介绍频分制红外遥控开关电路的设计与实现。遥控开关电路的类型很多,采用频分制具有电路简单、易于实现,可广泛应用于家庭、办公场所的开关控制。频分制有多种实现方法,该设计主要采用NE555定时器作为发射电路的核心器件,接收电路采用通用音频译码器LM567作为主要器件,制作方便,易于推广使用。经安装调试,控制效果较好。The design and implementation of the infrared remote-control switch with frequency dividing system are introduced. There are many types of remote-control switch circuit, while the infrared remote-control switch with frequency dividing system is simple and reliable, which can be widely used in home and office. There are many methods to realize the remotecontrol switch with frequency dividing system, this design adopts NE555 timer as the core device in transmission circuit, its receiving circuit uses universal audio decoder LM567as main device, it is easy to be realized and spreading used . The control effect is good by installing and debugging.
