摘　　要：介绍基于AVR单片机设计的一种智能红外遥控开关的原理及设计。该遥控开关能够实时识别和记忆常用遥控器发出的红外信号编码,并通过将接收到的红外信号与单片机存储在E2PROM的数据比较,从而控制遥控开关的通断,同时达到遥控器功能复用的效果。系统采用电容降压式直流稳压电源供电,与机械开关相比,它具有结构简单、体积小、重量轻以及安全可靠等优点,可广泛应用于家用电器的开关控制。The principle and design of an intelligent infrared teleswitch are introduced.The teleswitch is designed on the basis of AVR signal chip computer,can identify and remember the infrared signal coding emitted by the common remote controller,and can compare the received infrared signal with the data stored in the E2PROM by the single chip microcomputer to achieve the control of the on-off of the teleswitch and the multiplexing function of the controller.The system using the capacitance step-down DC power has the quality of simple structure,small size,light weight,and is safe and reliable for the household appliances.
