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
