Identity validation is carried out in load 5, and in the present embodiment, load 5 is a music door-bell.
In the present embodiment, audio collection becomes power amplifier module 12 to adopt integration module LM386, and it is a kind of audio collection success ratio amplifying circuit.The packing forms of LM386, plastic packaging 8 lead-in wire dual inline types and SMD are arranged, pin 2 is an inverting input, pin 3 is an in-phase input end, pin 5 is an output terminal, and pin 6 and pin 4 are respectively power supply and ground, and pin 1 and pin 8 are set end for voltage gain, pin 3 is in-phase input end current potentials, is reference with ground.Output terminal pin 5 is by automatic DC bias half to supply voltage simultaneously.When under the 6V supply voltage, its quiescent dissipation is 24mW only, makes LM386 be specially adapted to battery powered occasion.Specified supply voltage 4～12V gets 12V during work; Static current sinking is 4mA; Voltage gain is 20～200dB; When pin 1 and pin 8 were all opened a way, bandwidth was 300KHz; Input impedance is 50K Ω; Audio power 0.5W.Pin 6 connects working power voltage.Because voltage difference, amplification driving circuit 2 different and decoupling capacitor differences in parallel, the rising of every group of power supply, fall time must be variant.Feasible method: the power supply of will power on, the power down time is short is put into+the 12V place, selects the Vs of the relatively slow power supply of rising as LM386, but is not lower than lower limit supply voltage 4V.Pin 7 plays the effect of filtering noise to the bypass electrochemical capacitor C3 between the pin 4.Behind the working stability, pin 7 magnitude of voltage over the ground approximates half (6V) of supply voltage.Increase the appearance value of this electric capacity, can slow down that DC reference voltage rises, decline rate, just can effectively suppress noise, overcome device at the noise that powers on, produced owing to the moment saltus step of DC reference voltage during power down.Between pin 5 and load 4, meet output coupling capacitor C2, coupling capacitance C2 is 250 μ F, effect is to cut off direct current to exchange with coupling.Cut off DC voltage: DC voltage is crossed and may well be damaged load 4; Audible communication signal after coupling is amplified.It and amplification driving circuit 2 have constituted the single order Hi-pass filter.Reduce this capacitance, the amplitude that noise energy is impacted diminishes, narrowed width; The too low cutoff frequency that also can make improves.Change gain by the capacitor C 1 that is connected between pin 1 and the pin 8.For making peripheral cell minimum, when pin 1 and pin 8 were broken as the sky pin, audio collection became power amplifier module 2 voltage gain inside to be set to minimum value 20dB.If between pin 1 and pin 8, increase an outer meeting resistance R3, just the adjustable voltage gain, but maximal value is 200dB.
In the amplification driving circuit 2 of the present utility model, the first diode D1 is used for anti-interference, promptly prevents to import the interference of negative pulse, makes triode T only accept positive pulse as input signal; The second diode D2 is used for afterflow, promptly absorbs the electric current that the relay back-emf is produced.When fingerprint comparison produces a pulse input later on, high level voltage is 750mV, amplify to drive the relay adhesive by triode T, the i.e. first normal open switch AC closure, the first normally closed switch AB disconnects, the contact of relay is linked to each other to overcome some equipment because input pulse the is little shortcoming that can't drive with the equipment of required control.
Relay contact in the amplification driving circuit 2 links to each other with remote controlled transmitting circuit 3, see also Fig. 5, among the figure, the right-hand member of the switch SW 0 of remote controlled transmitting circuit, SW1, SW2, SW3, succeed the stationary contact A end of electrical equipment, the left end of switch SW 0 and SW1 is succeeded the C end of appliance contact, and the left end of switch SW 2 and SW3 is succeeded the B end of appliance contact.
See also Fig. 6 and Fig. 7, there is shown remote-control receiving circuit 4 of the present utility model, wherein, the VT among Fig. 6 end (effectively acknowledge, high level is effective) is linked to each other with E end among Fig. 7, the earth terminal of Fig. 6 links to each other with the earth terminal of Fig. 7.Adopt the decoding that does not have data output to use (being that OUT1, OUT2, OUT3, OUT4 do not have data output) to the chip PT2272 among Fig. 6.After the PT2272 of Fig. 6 energising (12V), PT2272 is in standby mode, makes PT2272 whether check received signal.Do not receive signal if having, then still rest on holding state; Otherwise after receiving signal, the VT end drives and is high level.After Fig. 6 left end antenna AN receives signal, Fig. 6 is by amplifying and signal of decoding circuit output (receiving effectively output high level), thereby the end of the E among Fig. 7 obtains signal, the coil JR of delayed relay 41 is got, relay is got to the second normal open switch A1B1 by the second original normally closed switch A1C1, and making load 5 is doorbell work.Owing to the delayed-action of delayed relay 41, switch is returned the second normally closed switch A1C1 again after a period of time again, and the second normal open switch A1B1 is disconnected, and music door-bell is stopped.
Principle of work of the present utility model is: after user fingerprints is confirmed, pulse signal of finger-print recognising instrument output, the transient state high level of fingerprint pulse gets the second diode D2 that is connect on the pipe collector after opening triode T, it is electric to be that relay coil J gets, and makes the first normal open switch AC closure.Again because the first normally closed switch AB and the first normal open switch AC are the interlock type switch, so the first normal open switch AC closure time, first normally closed switch AB disconnection.The closure of the normally opened contact of the first normal open switch AC makes transmitter unit obtain operating voltage, and remote controlled transmitting circuit adopts chip HS2262, the switch SW 0 of this chip HS2262, switch SW 1 closure, output radio transmission signal.
After remote-control receiving circuit 4 received signal, it was that doorbell is opened (musical sound rises) that the generation high level signal makes load 5.Because the effect of delayed relay 41 in the receiving circuit, after after a while, the normally closed contact of the first normally closed switch AB makes switch SW 2, switch SW 3 conductings of module HS2262, sends radio signal again.After remote-control receiving circuit 4 receives signal, produce high level signal and make doorbell close (musical sound stops).
Oscillation resistance among Fig. 5 between 15 of HS2262 and 16 pins is 4.7 megaohms, and the oscillation resistance among Fig. 6 between 15 of PT2272 and 16 pins is 820 kilo-ohms, and then the oscillation frequency of radio transmission and reception all is 315MHz.
In sum, fingerprint identification technology mainly contains and reads fingerprint image, extraction eigenwert, deal with data, blurs comparison with the fingerprint of having registered, and exports recognition result at last.Taken out a pulse signal of exporting after the fingerprint identification, the amplitude that records in this circuit is 750mV.This pulse signal is not enough to directly drive remote controlled transmitting circuit 3.Therefore, the utility model adopts amplification driving circuit 2, and pulse signal sends steering order to executive circuit after output buffer amplifies: order rises suddenly as the music tone ringer of executive circuit, to show identity validation.
The utility model also can be applied to remote control gate or any wireless control system; Input not only is confined to the fingerprint contrast, also can be the human body sensor input, ultrasound wave input, photoelectric sensor input etc.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
