摘 要
 本设计是基于单片机的智能红外遥控系统，主要介绍遥控系统的组成，各个器件的电路原理和驱动程序，以及智能遥控的原理。利用本系统，可以实现各种不同红外编码方式的判断、学习、存储和发射，集成各类电器设备的遥控功能，取代各设备林林总总的外遥控器。
 首先要了解红外遥控的发射电路和接收电路。红外遥控的发射电路是采用红外发光二极管来发出经过调制的红外光波；红外接收电路由红外接收二极管、三极管或硅光电池组成，它们将红外发射器发射雕红外光转换为相应的电信号，再送后置放大器。由于红外线为不可见光，因此对环境影响很小，再由红外光波动波长远小于无线电波的波长，所以红外线遥控不会影响其他家用电器，也不会影响临近的无线电设备。除了发送器,接收器以外,红外遥控系统还需要一系列外围电路。

Abstract
 The design is based on chip Micro-computer with smart terminal control system, mainly on the remote control system composed of various components of the circuit principle and drivers, and the principles of smart remote control. The use of the system, can achieve various infrared encoding judgement, learning, memory and launch, integration of the various types of electrical equipment remote control functions, to replace the wide range of equipment,remote control.
 Firstiy, We must understand the infrared remote control transmitter and receiver circuit. The infrared remote control transmitter is to use infrared light-emitting diode issued after modulation of infrared light waves, infrared receiver circuit by the infrared receiver diodes, transistors, or silicon-cell component, they will be infrared transmitter of the Instructional infrared light Converted to the appropriate signal, returned home after the amplifier. As for the infrared is not visible, so little effect on the environment, by infrared light waves long-term volatility is less than the wavelength radio waves, infrared remote control will not affect other household appliances, will not affect nearby radio equipment. In addition to transmitters, receivers, infrared remote control system also need a series of external circuit.
