毕业设计（论文）基于单片机的家用电器电源的遥控控制器设计.doc

摘 要 随着家用电器的日益普及和红外技术的成熟两者结合的产物应运而生，而目前主要的结合产物就是红外遥控与控制器。本设计集中介绍了一种基于89C51单片机的红外控制器的设计方法，其在某些思路上比较新颖并有一定的参考价值。这款红外控制器采用了比较成熟的红外接收组件和红外信号解码芯片代替过了过于复杂的红外接收电路，使设计者免去了过于复杂的电路调试工作，同时也最大的保证了信号在传输中的安全性。它在原理上利用了红外信号在一定距离内的直线传输特性和在某些红外光频段信号不失真的特性。控制部分电路主要采用技术上较为成熟的继电器及光电隔离器件，并且巧妙的利用了三极管的放大作用，使得控制部分电路极其节约和有效。该控制器有很大的发展前景，它是将来“电脑管家”的雏形，它也是广大工作繁忙或行动不便人群的帮手。在以后的居家生活中它一定起到重要作用。 关键词：控制器； 红外； 遥控；家用电器 家用红外遥控控制电源开关的设计 有专用315MHZ发射和接收芯片！也有红外接发芯片；可以合在一起做就可以在直径50米内控制你的家电了！只要买回来对照电路图来做就行了！一般不用调试就能用了，外壳先买好再设计！！可用PowerPCB来设计！！  ABSTRACT With the increasing popularity of hausgeraete and maturity of infrared technology, the product of a combination of them came into being, now, the main product is a combination of infrared remote controller and the controller. Focus on the designing of the infrared controller with a microcomputer of 89C51, which has some more innovative ideas and referenced value. The infrared controller not only use very maturity device and the infrared decode chip to replace the infrared take-over circuit, which is too complicated, but also ensure the security when the signal in the transmission. It save a lot of work of debugging of circuit .It takes the principle that infrared signals can transmit in a straight line within a certain distance , and the infrared light do not lose the characteristics in a certain frequency band. In the controlling part, it uses electro-optical isolation devices and the relay, together with the characteristic that dynatron can magnify current, which make it very economical and effective. The controller has beautiful development prospects in the future, it is the embryonic form of Computer Manager .It is also the helper of the people who has a lot of work and the deformity people. In the livings of every family it will certainly play an important role in the future.  Key words: controller; infrared; remote control; hausgeraete 目录 1 引言·····················································1 1.1选题背景及意义······································
