【正文】 in the infrared receiving attention finished first carrier remote mon carrier frequency for 38kHz, this is transmitted by using 455kHz TaoZhen to the launch of crystals were integer frequency, frequency coefficients, so monly 12, so 455kHz/12 hundredth kHz 38kHz hundredth remote control system adopts 36kHz, 56kHz,etc, general 40kHz launched by the crystals of oscillation frequency to remote characteristic is not influence the surrounding environment and does not interfere with other electric to its cannot penetrate walls, so the room can use mon household appliance of remote control without mutual interference, Circuit testing is simple, as long as given circuit connection, generally does not need any missioning can work, Decoding easily, can undertake multiple remote each manufacturer produces a great deal of infrared remote applicationspecific integrated circuit, when need press diagram suo , the infrared remote now in household appliances, indoor close(less than 10 meters)in the remote control is widely infrared remote control system of infrared emission control buttons, there are many parts general representative of different control pressed a button, correspondingly in the receiver with different the output state can be roughly divided into pulse, level, selflocking an interlock, data five forms.“The pulse output is according to launch” when the button, the receiver output terminals output corresponding “effective”, a pulse width 100ms in general.“Level” refers to the output launch press button, the receiver output corresponding output level, effective transmit to loosen the receiver level “effective pulse” and “effective”, may be of high level is low, and may also depend on the output corresponding static state, such as feet for low, static high for effective, As for the static, “l(fā)ow” high most cases, “high” for effective.“since the lock” refers to launch the output of each time you press the button, a receiver output corresponding change, namely originally a state for high level into a low level, originally for low level into high output power switch and mute as control also called the output form for “invert”.“The interlock” refers to multiple outputs each output, at the same time only one output, The TV sets of this case is selected, the other is like the light and sound input speed, etc.“Data” refers to launch the output some key, use a few output form a binary number, to represent different , the receiver except a few data output, but also a “valid” output data, so the timely to collect output form with singlechip microputer or are monly used addition to the above output form outside, still have a “l(fā)atch” and “temporary” two socalled “l(fā)atch” refers to launch the output signal of each hair, the receiver o
