摘要
当今社会科学技术的发展与日俱增,人们的生活水平也是日益提高,为了减少人们的工作量,所以对各种家用电器、电子器件的非人工控制的要求也是越来越高,针对这种情况,设计出一种集成度比较高的控制体系是必然的。单片机的集成度很高,它具有体积小、质量轻、价格便宜、耗电少等突出特点,尤其耗电少,又可使供电电源体积小、质量轻等优点,因此广受人们的青睐。
本文详细介绍了学习型红外线遥控器的软硬件设计方法,并给出了具体的各单元电路设计、程序设计及程序流程图。在硬件设计中,选取AT89C52型号单片机为核心器件,并给出外围电路模块如红外线接收模块、红外线发射模块以及外部控制模块等组成部分的设计实现。本学习型红外线遥控器采用最小化应用模式设计,电路简单,尤其是通过大量不同遥控码的特征分析,在遥控码的读入时选择了最佳采样间隔,使遥控码的学习成功率大大提高。因此它能成功地学习各种红外遥控设备的编码,并通过40 kHz载波发送学忆信号。实现了对各种各样红外遥控的学习,从而实现了学习型遥控器。

Abstract
In today's society, the development of science and technology increasing people's standard of living is increasingly improved, in order to reduce the workload of people, so a range of household appliances, electronic device of the artificial control requirements is also more and more high, in this kind of situation, design a kind of integration of relatively high control system is inevitable. MCU integration too high, it has small volume, light quality, price cheap, less consumption such prominent characteristics, especially less consumption, and can make the power supply, small volume, light quality.
This design detailed introduces the hardware and software design method of learning remote control, and gives the specific each unit circuit design, programming and program flow chart. In the hardware design, selection of AT89S52 puter as the ponent models, and give peripheral circuit module such as infrared receiver module, infrared emission modules and external control ponent design implementation. This learning infra-red remote adopts minimize application pattern design, simple circuit, especially by a lot of different characteristics of remote yards i
