control system adopts 36kHz, 56kHz, etc, general 40kHz launched by the crystals of oscillation frequency to decide.РInfrared remote characteristic is not influence the surrounding environment and does not interfere with other electric equipment. Due to its cannot rate walls, so the room can mon household appliance of remote control without mutual interference, Circuit testing is simple, as long as given circuit connection, generally does not need missioning can work, Decoding easily, can undertake multiple remote control. Because each manufacturer produces a great deal of infrared remote application-specific integrated circuit, when need press diagram suo ji. Therefore, the infrared remote now in household appliances, indoor close (less than 10 meters) in the remote control is widely used.
