1、1 摘要 作为传统的家用电器，随着空调的普及，电风扇的市场地位受到了巨大的冲击，传统的开关、调速功能已经不能满足市场的需求。人们希望电风扇在体积小，使用方便等的基础上，能够拥有更多的功能，而红外遥控的广泛应用及单片机技术的成熟则使得红外遥控系统成为了电风扇的发展趋势。 红外线遥控是目前使用最广泛的一种通信和遥控手段，而红外遥控电风扇已经过市场推广反响很好，并有专门的掩 模 芯片作为主控芯片，先用 AT89C52 为核心部件，加以扩展实现红外遥控电风扇系统，并以指示灯显示档位，具有开关及多档位等功能。 经过多次的测试与电路 调整，系统各项功能均能正常实现 关键词： 红外遥控；电风扇；单片机；芯片
