1、电风扇遥控器设计毕业设计摘要红外遥控技术大大提高了劳动生产率、降低了成本、减轻了工人劳动强度、改善劳动条件。而微机技术出现,使现代科学得到了质的飞跃,给现代工业测控领域带来了一次新的革命。红外遥控系统是通过红外线的精准定位控制模式来控制被控对象,整个控制系统主要集合了数字电路以及模拟电路。硬件电路则包括了红外发射电路以及红外接受电路两部分。发射电路主要将红外信号通过键盘输入、编码调制以及红外发生器等一系列硬件电路传输给接受电路,而接收电路则解调、解码等电路来识别所接受的红外信号。电风扇作为一种老牌的电器,具有价格便宜、摆放方便、体积轻巧等特点,占有大部分的市场份额,市场的需求促使了电风扇的发
2、展,精准的遥控开关设计能够提高电风扇的工作性能,提高舒适性、稳定性。本设计以AT89C51单片机作为核心,综合了单片机中断系统、定时器、计数器等功能,结合红外光的优点设计出了一款电风扇遥控装置。针对不同功能的遥控操作实现途径,红外遥控发射器通过识别不同的红外光线频率来区别不同功能的操作。红外遥控接收器则经过识别红外线频率、查表识别具体要操作要求,完成对被控对象的实时控制。关键词:红外遥控;电风扇;数字电路;模拟电路;AT89C51I毕业设计AbstractInfraredremotecontroltechnologygreatlyimproveslaborproductivity,reduc
