高精度、多功能、低功耗，是现代科技发展的趋势。

在这种趋势下，窗帘的数字化、智能化已经成为现代生产研究的主导设计方向。

万用遥控器存储有很多家电遥控器的编码，最大缺点是灵活性差，即使是采用同一遥控芯片的遥控器可以选取不同的识别码（客户码）和命令码（数据码），从而构成几乎无数种具体的用法。

新的遥控编码组合随新的家电机型层出不穷，导致采用专用集成电路（ASIC）或掩模型单片机（MaskROM MPU)制作的万用遥控芯片总会对一些设备，而且是越来越多的设备无法起作用。

学习型遥控器是将原家电遥控器对准学习型遥控器的接收器逐一按键，从而准确地记录该遥控器的波形，应用时再将这一波形再现、发射出去。

这样的优点是通用性强，缺点是遥控器内存储器的容量极基有限，一般只能记录数十人键的波形，更换设备就更重新学习。

家电控制器不象万用遥控器那样具体到芯片的每一种应用以及每个码的功能，也不需要象学习型遥控器那样机械地记录每个按键的波形，而是综合了遥控编码方式的诸多因素形成特征字，将需要改变极大地节省了数据存储量而机软件去处理，PC的部分数据编码分离出来由．文档来源为:从网络收集整理.word版本可编辑.欢迎下载支持.又完全不失通用性。

这样一来就具备了二者的优点而克服了相应的缺点。

单片机在电子产品中的应用已经越来越广泛，在很多的电子产品中也用到了红外控制。

随着窗帘红外控制器应用范围的日益广泛和多样，各种适用于不同场合的窗帘控制器应运而生。

红外线窗帘遥控控制器是最新研制的一种高科技产品，它不但取代原有的无线遥控窗帘控制器，而且工作可靠，4种不同的工作方式任意选择，数字自动测试环境亮度，整点报时，电机工作鸣响提示，数码时钟等功能，满足不同用户的需要。

AbstractAs electronic technology industrial restructuring, the rapid development of production technology, continuous improvement of living standard, household appliances became more common, the market for infrared remote control system demand is growing. High-precision, multi-function, low power consumption, isthe modern trend of technological development. In this trend, the number of curtains, intelligence has become a modern production of the dominant design direction. 10 000 with the remote storage has a lot of home appliances remote control codes, the biggest disadvantage is that flexibility is poor, even using the same remote control chip remote control can select a different identification number (customer code) and the command code (data code), which is almost countless kind of specific use. Combined with the new remote control codes emerging new appliance models, leading to use of application specific integrated circuit (ASIC) or a cover model for SCM (MaskROM MPU) chips produced bythe Federation-purpose remote control for some equipment, but more and more devices can not work. Learning is the original home appliances remote control learning remote at the receiver one by one remote control button, which accurately record the waveform of the remote control, then the waveform reconstruction applications, launch out. This has the advantage of versatility, drawback is the remote control base within the memory capacity of the very limited, generally only record the waveform dozens of keys, replacement of equipment is even more re-learning. Appliance controller as a universal remote control is not specific to the chip as an application, and each code for each function, do not need a learning remote so as to mechanically record thewaveform of each button, but integrated remote control encoding characteristicsof the many factors that form the word, will need to change some of the data encoded by a separate PC, software to deal with significant savings in datastorage and entirely without losing generality. This way you have already had to overcome the advantages of both the corresponding shortcomings.MCU in the application of electronic products have been widely used inmany electronic products also use the infrared control. As the curtain infrared controller applications become increasingly wide and diverse range, all for different occasions curtain controller came into being. Infrared remote control curtain is a newly developed high-tech products, which not only replace theoriginal controller, wireless remote control curtains, and be more reliable, 4arbitrary choice of different ways of working, digital automatic test environment brightness, the whole point of the newspaper Electrical work ringing tips, digital文档来源为:从网络收集整理.word版本可编辑.欢迎下载支持.clock and other functions to meet the needs of different usersKey words: infrared remote control, timing, events, programming引言智能家居，或称智能住宅，以住宅为平台，兼备建筑、网络通信、信息家电、设备自动化，集系统、结构、服务、管理为一体的高效、舒适、安全、便利、环保的居住环境，尽显便捷将家中的各种设备(如音视频设备、照明系统、窗帘控制、空调控制、安防系统、数字影院系统、网络家电等)通过家庭网络连接到一起。
