ABSTRACT
With the development of science and technology,MCU is widely used in many fields,such as smart domestic appliances,instrucments etc due to its relialility,low prices and high quality. Nowdays,the developing trend of the MCU which is used in the control of domestic appliances tends to have simple appearance,multiple functions and supere ponenils.
The thesis predicts the multiple desgne that MCU controls the domestic applinces through infrared ray. It also describes infrared ray sending and receiing working proess and its program to operate its software.
In this thesis,I anlyzed the systems software and hardware structure and its working process,using relatives knowledge of MCU’s data analysis.
I also drew a picture of the detailed process working program. I think the design will be better than that. Before,My system onsists of STC89C52RC MCU and its recovered circuit 、XTXAL、circuit 、1602LCD screen data’s snding and receiving circuit,1602LCDscreen、
Keyboard control,appliances control circuit,which makes the control circuit thrugh intfrace ray on domestic appliances simple,accurate and multiple .
In the thesis, I divided ti into four parts. In each part , I described respectvely the system’s structure and working process in detail . I’m sure it will be easy to understand .

前言
随着社会的不断进步和科技的不断发展,各种多媒体系统已经成为人们工作、学习、生活中不可缺少的工具。如空调机、彩色电视机等。但是,所有这些设备都各自带遥控器,而且不同的设备所遵循的红外传输规则也不尽相同,操纵这些设备得使用多种遥控器,这给使用者带来了诸多不便。
红外遥控器具用使用方便、功耗低、抗干扰能力强的特点,因此它的应用前景是不可估量。市场上的各种家电的红外遥控系统技术成熟、成本低廉,但是,
