Summary of the invention

Goal of the invention and beneficial effect: because the quick update of electronic product, each family various Infrared remote controller of can leaving unused, as: the Infrared remote controller such as colour TV, VCD, DVD, air-conditioning, electric fan and electric heater.The user can be according to own needs, utilize these idle Infrared remote controller, come the high level of the general reception controller output of described Infrared remote controller to control relevant electrical appliance or electronic equipment with the present invention, as: at output terminal adjunction triode or the relay of the general reception controller of Infrared remote controller, utilize relay can control illuminating lamp, control barndoor gate, also can pass through DC MOTOR CONTROL electrically driven curtain etc., make the how new effect of Infrared remote controller performance.

Circuit working principle and function: IC1 is the infrared remote receiver module (PNA4602M) of 3 pins in the circuit of the general reception controller of Infrared remote controller, and this inside modules is comprised of infrared receiving terminal, infrared signal amplifier and detuner etc.Time base circuit IC2 and resistance R 2, capacitor C 2 form the monostable timing device in the circuit, and its timing is determined by time constant resistance R 2, time constant capacitor C 2.The present invention has only used 1 d type flip flop among the double D trigger IC3, and it is connected into bistable circuit, realizes lock function.

When infrared remote receiver module I C1 does not receive the infrared light that telepilot sends, the output of infrared remote receiver module I C1 is in high level, this high level is added to the trigger end (the 2nd pin) of time base circuit IC2 timer, make monostable circuit keep waiting status, the output terminal of time base circuit IC2 (the 3rd pin) is in low level always.After infrared telepilot faces toward infrared remote receiver module I C1 and presses the upper arbitrary key of Infrared remote controller (any a), the infrared signal of its emission will be received by infrared remote receiver module I C1, this moment, the output terminal of infrared remote receiver module I C1 will send a series of high, just low level, the negative pulse string, at these just, in the negative pulse string, as long as there is 1 negative pulse (low level) to be added to the trigger end (the 2nd pin) of time base circuit IC2, monostable circuit can be triggered, make the 3rd pin output high level of time base circuit IC2, holding time by resistance R 2 of high level, the time constant of capacitor C 2 and deciding, when design, the time of monostable output high level needs only the T.T. greater than Infrared remote controller institute transmit burst.

Monostable circuit an anti-shake effect of switch arranged, no matter what high and low level signals the output terminal of infrared remote receiver module I C1 exports, when having 1 low level to be added to the trigger end of time base circuit IC2, its 3rd pin will be exported the high level pulse of certain hour.

The high level of the 3rd pin output of time base circuit IC2 makes LED1 once glittering, illustrate that receiving controller has received infrared remote-controlled signal, this high level also is added to the 3rd pin of double D trigger IC3 as clock signal (CLK) simultaneously, the bistable state (latch) that double D trigger IC3 is formed is triggered, make output terminal (the 5th pin) and Q end (the 2nd pin) the output high level of double D trigger IC3, this high level can control signal be controlled circuits, LED2 is lit simultaneously, and expression double D trigger IC3 has high level output.

Press after any key of Infrared remote controller, the high level of exporting because of time base circuit IC2 monostable only can keep certain hour, infrared remote receiver module I C1, time base circuit IC2 can be in waiting status again again, but the high level of double D trigger IC3 output will keep always, only have when pressing again an any key of Infrared remote controller, the output terminal of infrared remote receiver module I C1 just produces a series of high, low level pulse, the composition monostable circuit of time base circuit IC2 is triggered again, its the 3rd pin is exported again the 3rd pin (CLK) that high level is added to double D trigger IC3, this moment double D trigger IC3 the 5th and the 2nd pin output low level, the LED2 lamp is gone out, and circuit is just finished once circulation like this.The high level signal of double D trigger IC3 output namely can be used as the control signal of other circuit.
