The utility model content

Goal of the invention and beneficial effect: because the quick update of electronic product, our each family some 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 utilize these idle Infrared remote controller, come the high level of described universal infrared receiving control device output to control relevant electrical appliance or electronic equipment with the utility model, as: at output terminal adjunction triode or the relay of universal infrared receiving control device, utilize relay can control illuminating lamp, barndoor gate, also can pass through DC MOTOR CONTROL electrically driven curtain etc., make the more new roles of Infrared remote controller performance.

The circuit working principle: IC1 is infrared remote receiver module (PNA4602M) in the circuit of universal infrared receiving control device, and this inside modules is comprised of infrared receiving terminal, infrared signal amplifier and detuner etc.Time base circuit IC2 in the circuit and resistance R 2, capacitor C 2 form the monostable timing device, and its timing is determined by the numerical value of resistance R 2, capacitor C 2.The utility model has only been used 1 d type flip flop among the double D trigger IC3, and it is connected into bistable circuit, realizes the duty lock function.

When infrared remote receiver module I C1 does not receive the infrared light that telepilot sends, the output terminal of infrared remote receiver module I C1 is 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.When infrared telepilot faces toward infrared remote receiver module I C1, after pressing 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 can send a series of high and low level pulse strings, in train of impulses, as long as there is 1 low level to be added to the trigger end of time base circuit IC2 (the 2nd pin), monostable circuit namely is triggered, make output terminal (the 3rd pin) the output high level of time base circuit IC2, holding time of high level decided by the time constant of resistance R 2, capacitor C 2.

Monostable circuit has the anti-shake function of switch, 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 of certain hour.

This high level is added to the 3rd pin of double D trigger IC3 as clock signal (CLK), 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 be controlled circuits, LED 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 LED lamp is gone out, and circuit is just finished once circulation like this.The high level signal of double D trigger IC3 output can be used as the control signal of other circuit.
