Fig. 3 shows the power circuit diagram of the utility model Smart Home infrared remote control switch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Please refer to shown in Fig. 1, the utility model Smart Home infrared remote control switch comprises Infrared Remote-Control Sending device and infrared remote-receiver, Infrared Remote-Control Sending device comprises keyboard matrix, coding demodulator and the LED infrared transmitter connecting successively, when pressing the different key of keyboard matrix, by scrambler, produce specific binary pulse coded signal correspondingly, this binary pulse coded signal is first modulated on the carrier wave of 38KHz, after amplifying, the infrared ray that excites infrarede emitting diode LED to be transformed into wavelength 940nm blazes abroad.Infrared remote-receiver comprises photoelectric conversion amplifier, demodulating and decoding device and the controller connecting successively, photodiode is transformed into electric signal by the infrared signal of reception, through detection, amplify, filter the carrier signal of 38KHz, recover original command pulse, then send into demodulating and decoding device and identify decoding, solution translates the content of remote signal, and according to controlling the corresponding control signal of fuction output, be sent to controller and do corresponding processing.
Shown in figure 2, according to the conception of above-mentioned Smart Home infrared remote control switch, controller adopts single chip computer AT 89C51 to realize, and demodulating and decoding device adopts dual tone multi-frequency dtmf generator MT8880 to realize.This switch employing single chip computer AT 89C51 and chip MT8880 are as the design's core parts, Intelligent bus type switch is realized system is controlled by AT89C51 and chip MT8880, the infrared remote control that adopts AT89C51 to realize is more easily realized and being connected of Intelligent bus type switch, the infrared remote control that adopts AT89C51 to realize is improved realization on the basis of general infrared remote control system, its essence adopts single chip computer AT 89C51 to control infrared remote control receiving unit exactly, when integrative infrared receiver receives after infrared remote-controlled signal, convert light signal to electric signal, through amplifying, demodulation, after filtering, original encoding signal is sent into and in single chip computer AT 98C51, carried out signal identification, decoding, then process accordingly, reach the object of control apparatus.
According to the conception of above-mentioned Smart Home infrared remote control switch, continue referring to shown in Fig. 2, also comprise relay circuit JK1A to JK5A and hummer, relay circuit is connected with the P2 mouth of single chip computer AT 89C51, and hummer is connected on 13 pin of single chip computer AT 89C51.In infrared remote switch circuit figure, after switching on power, the hummer that 13 pin of AT89C51 connect can ring, and the light emitting diode that 14 pin connect is simultaneously once glittering, then extinguishes.P1 light-emitting diode display that mouth connects do not show, relay circuit JK1A to JK5A all disconnects, and these all show that infrared remote control switch does not receive signal, in this prompting, waits for.Now, if when the numeral of telepilot " 1 " is pressed, the receiver of remote-control sytem SM0038 in the circuit diagram of infrared remote control switch in the drawings receives the infrared signal from remote control transmitter transmitting, convert the infrared signal of reception to electric signal, after amplification, demodulation, filtering, through the first pin of infrared remote receiver, original encoding is inputted to 12 pin of AT89C5.Then by AT89C51, received original encoding signal is judged, identification etc., then make the processing of response.
