The invention discloses long-distance infrared remote-controlled device and method used for embedded equipment, belonging to the technical field of electronic information. The device comprises an infrared remote-controlled signal emission device and an infrared remote-controlled signal receiving device. In the remote-controlled method, after adding a sync character in front of a binary encoding abutton corresponds to, the infrared remote-controlled signal emission device converts the binary encoding into a high-low electric level combination corresponding to an infrared signal encoding mode;then a 38k sinusoidal wave modulates the binary encoding and an infrared emitting head sends out the modulated binary encoding; after receiving the signal modulated by the 38k sinusoidal wave, an integral infrared receiving head of the infrared remote-controlled signal receiving device converts the signal into a pulse signal consisting of a high-low electric level; the pulse signal is output to aGPIO lead foot of an embedded equipment through an output lead foot of the integral infrared receiving head; the pulse signal consisting of the high-low electric level triggers an interruption of theGPIO port; during interruption processing program, lasting times of a high electrical level and a low electrical level are calculated out through timing; thus decoding can be carried out, and the high-low electric signal is deciphered into binary data.
