摘要
在电子化的世界中，红外遥控技术广泛的应用于我们的生活。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，为了避免不同品牌、不同型号的设备之间产生误操作，人们在不同的设备中使用不同的传输规则或者识别码，这就使得各个型号的遥控器都只适用于各自的遥控对象，容易造成实际使用中遥控器多而杂，经常搞混的结果。本设计要求实现一种智能学习型红外遥控器的实现方案。
本文通过研究红外编解码、红外发射接收、MCU控制、键盘接口等技术，以单片机为主要控制中心，外围电路主要包括接收电路、发射电路、键盘电路、显示电路以及存储电路。设计中重点及核心部分是通过软件解码来实现对红外信号的自学习，并由单片机控制将学习的信号存储及转发。

Abstract
In the electronic world, the infrared remote control technology is widely used in our lives. Various appliances on the market have the technology of infrared remote control system with maturity and low cost. However, to avoid different brands and between different types of equipment malfunction, people use different devices in different transport rules or identification number, which makes various types of remote control apply only to their remote objects and easy causes confusing results that the actual use of the remote control are many and complex. The design requirement is to achieve an intelligent learning IR remote control implementations.
By studying infrared codec, infrared transmitting and receiving, MCU control, LCD display technology, remote control of other learning and learning sent successfully restored infrared remote control system key and core part of the design is that through software decoding it can achieve the self-study function of the infrared signal and be controlled by MCU to make the learned signal in store and forward.
Keywords: Infrared remote controller；The 38KHZ carrier；Self-study；Infrared remote receiver；Infrared remote transmitter
