学习型万能遥控器的设计与实现
摘  要
  
   随着万能遥控器家用电器的出现和推广，曾经给我们生活带来方便的红外遥控器反而显得无用武之地。一方面，数字电视机顶盒、DVD、电视机、音响、空调等家用电器都是自带遥控器，操纵这些需要使用多种遥控器，这给使用者带来了许多不便之处。另外一方面，红外遥控信号因为需要直视空间、并且要受短短几米距离的限制，而导致很多场合无法适用。学习型万能遥控器却能够把各种电器集中控制，克服了红外遥控器只能识别唯一设备的局限性，从而拓宽了应用范围，方便了我们的生活。学习型万能遥控器主要功能包括红外信号转发、克服对直视空间控制的依赖以及克服接收距离短的缺点。红外信号学习,可以把多个红外信号学习在一个遥控器上,有效避免频繁更换遥控器的尴尬情况，当然学习功能也兼有转发功能的特点。

ABSTRACT

 With the infrared remote control of household appliances has increased, would have to bring convenience to our lives instead of the infrared remote control to give us trouble. Digital TV set-top boxes, DVD, TV, stereo, air conditioning, due to various equipment comes with remote control, manipulation of these devices may use a variety of remote control, a lot of inconvenience to the user. On the other hand, infrared remote control signal because of the need open heart space, and subject to just a few meters away from the restrictions, and lead can not be applied on many occasions. The design allows centralized control of various electrical energy to overcome the remote control device to operate only against the limitations and broaden the scope of application, to facilitate our lives. Design of the main functions of the transmitted IR signal can overcome the need to look into space, the disadvantage of receiving a short distance; infrared signal learning, can learn in a number of infrared remote control signals, and effectively avoid the embarrassment of frequent replacement of the remote control, of course learning function is also the characteristics of both forwarding. Key words:  infrared remote control  universal remote control  IR learning  signal relay
