Along with the time development，remote control technology is also developing fast，and the infrared remote control is unceasingly applied in each domain, like electrical appliances thing, industry domain, and military singlechip applied systems and so on. In many singlechip applied systems, Unelectricity signal is always used, especially light signal transmit control information and data information, in order to achieving remote control. Infrared-ray remote control is now the most widely used in controlling device in the world. This article introduces an infrared-ray remote control installation which based on AT89C51 singlechip. And transmit and receive equip to realization wireless control. It emphasizes on the axiom of the installation and the realization of electric circuit, while giving the procedure of C51 which can realize the controlling installation.
Keywords：AT89C51 singlechip ; infrared-ray ; remote-control
