1、基于单片机的红外遥控器设计摘要：随着电子技术的发展，家用电器种类的增加和无线遥控产品的普及，红外遥控器的使用越来越频繁。本设计主要应用了AT89S52型单片机作为核心，综合运用了单片机中断系统、定时器、计数器等知识，应用红外光波长短、抗干扰、工作可靠性高的优点。该设计主要包括红外发射和红外接收模块，然后分别对这两个模块进行软件的编程。对于遥控操作的不同，遥控发射模块通过对红外光发射频率的控制来区别不同的操作，遥控接收模块通过对红外光接收频率的识别，判断出控制操作，来完成整个红外发射、接收过程[1]。如今，由于嵌入
2、式的广泛应用，促进了新一代红外遥控器的发展，将微型计算机芯片融入到遥控器中，使之使用更加方便快捷，也使人们的生活简易化。随着时代的进步，人们对生活物品的要求也越来越高，为了满足消费者的需求，所以将先进的单片机加入到家庭中的电器遥控器中是符合大众要求的。关键词：遥控器；红外发射；红外接收；单片机TheDesignofInfraredRemoteControllerBasedonSingle-chipComputerAbstract：Withthedevelopmentofelectronictechnology,i
