摘要

　　　在電子化的世界中，紅外遙控技術廣泛的應用于我們的生活。市場上的各種家電的紅外遙控系統技術成熟、成本低廉，但是，為了避免不同品牌、不同型號的設備之間產生誤操作，人們在不同的設備中使用不同的傳輸規則或者識別碼，這就使得各個型號的遙控器都只適用于各自的遙控對象，容易造成實際使用中遙控器多而雜，經常搞混的結果。本設計要求實現一種智能學習型紅外遙控器的實現方案。

　　　本文通過研究紅外編解碼、紅外發射接收、MCU控制、鍵盤接口等技術，以單片機為主要控制中心，外圍電路主要包括接收電路、發射電路、鍵盤電路、顯示電路以及存儲電路。設計中重點及核心部分是通過軟件解碼來實現對紅外信號的自學習，并由單片機控制將學習的信號存儲及轉發。

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.
