Background technology

Society is improving, science and technology is in development, and various products, substituting, open the door and open the door from mechanical key over the past thousands of years, the password developing till now opens the door, opening door of remote-control, phone opens the door, although there have been many such products on market, but the most door-opening mode that opens the door or used mechanical key, although this just proves that other door-opening mode is advanced, goes back the place of Shortcomings, just do not obtain universal and extensive utilization.

Phone opens the door and also will use telecontrol engineering, and present remote control product is a lot, and these all become remote control interference source, want to make remote control unaffected, obviously also need certain technology, but be not but resolved for a long time, thereby caused phone open the door development and the use of series products.

Summary of the invention

Main purpose of the present utility model is to implement a kind of phone to open the door, and its circuit is simple, and level of confidentiality degree is high, has solved the problem of can only phone opening the door and can not phone closing the door, and in rhythm of life fast today, can be popularized.

The measure that the present invention takes is:

1, discrete information controller is by mobile phone, multi-function jack, and discrete switching logic circuit, vibration damping thing, installation box forms jointly.

Wherein: multi-function jack inserts in the socket of mobile phone, draws respectively cell-phone bell holding wire and cellular phone power supplies line, and cell-phone bell holding wire is connected to the input of interface circuit in discrete switching logic circuit.

Discrete switching logic electric routing switch circuit, interface circuit, switch passage, pass door composition.

Switching circuit is made up of NPN triode and PNP triode, the emitter of PNP triode is connected on power firestreak, the collector electrode of PNP becomes the power supply of switching circuit, the base stage of PNP triode connects the collector resistance of NPN triode, the grounded emitter of NPN triode, is connected to the output of interface circuit after base stage connection base resistance.

Passage opens the door: after the output of the integrating resistor interface circuit in passage that opens the door, connect the positive pole of integrating capacitor, the minus earth of integrating capacitor, first inverter opening the door in passage connects the positive pole of integrating capacitor, the input of second inverter in passage of opening the door is joined with the output of first inverter in passage of opening the door, and the output of second inverter in passage that open the door becomes enabling signal output.

Close door: the output of one end connecting interface circuit of isolation resistance, the other end of isolation resistance becomes the signal output part of closing the door, the signal output part of closing the door connects the positive pole of clamp diode, and the negative pole of clamp diode connects the output of first inverter in passage that opens the door.

2,, after multi-function jack inserts in the socket of mobile phone, refill in installation box after superscribing vibration damping thing.

3, discrete switching logic circuit is to be screwed in installation box.

For the measure that clear interpretation is taked, first make the following instructions:

The principle that phone opens the door is: operator carries out and calls out with phone opponent machine without, mobile phone is received after bell signal, take out bell signal through socket, then be input to and in two-way function electronic logic circuit, carry out logic transition, the bell signal of " length " in when operation and " short " can be transformed into transmitting of opening the door or close the door, transmitting by adapted is sent, and when the actuator in door receives after remote control command, then carries out corresponding logical action.

As follows to further illustrating of measure:

One, can automatically tell the principle of closing gate signal and enabling signal:

User calls out the mobile phone in the utility model, mobile phone is received after bell signal, take out bell signal through multi-function jack, then be input to and in two-way function electronic logic circuit, carry out logic transition, the bell signal taking out is after interface unit (2 in Fig. 1), what first enter is the resistance (8 in Fig. 1) closing in door, this is owing to there being an integrating capacitor (4 in Fig. 1) to need charging in the passage that opens the door, integrating resistor (3 in Fig. 1) has formed regular hour constant with integrating capacitor, once therefore there be bell signal, must be first to open pass door, close door very simple, only after a resistance, just form signal output, connect the bit line of the integrated circuit of encoding in multi-code transmitter, the signal that now remote control is sent is to close gate signal, when multi-function jack output is that long signal is that the cell-phone bell time is long, although there is pass gate signal of short duration (this does not form harmful effect to logic), once the time constant of long signal is greater than after the time constant by integrating resistor (in Fig. 1 3) and integrating capacitor (4 in Fig. 1), first inverter (5 in Fig. 1) in the passage that opens the door, the output of first inverter plays two aspects, the one, after second inverter (6 in Fig. 1) opening the door in passage, again export positive signal, connect the bit line of radio transmission coding integrated circuit, the signal that now remote control is sent is enabling signal, the 2nd, through the signal of clamp diode (9 in Fig. 1) clamper pass door, because this point and the input of closing in door have isolation resistance (8 in Fig. 1), so be output as when low when closing first not gate in door, still can not affect the logic of closing second not gate in door.What think explanation is simultaneously, from security personnel's angle, the program of closing the door is conducive to security personnel, and the program of opening the door is unfavorable for security personnel, so can not mistake, so long signal for the present invention (call signal for a long time) is opening door operation, with the call signal of short time be the signal operation of closing the door, be not easy to occur mistake, because long-time operation has the character of " confirmation ".

Be that quiescent dissipation is extremely low and use the benefit of inverter, when input signal changes, can automatic fitration reconcile, so the voltage of output can be protected, antijamming capability is strong, promotes load-carrying ability, reduce time delay, so in the time having had input end signal, output is reliable in time.

Two, 12 in Fig. 1 formed switching circuit with 14 two triodes in Fig. 1, when mobile phone has had bell signal, base resistance through NPN triode (12 in Fig. 1) starts NPN triode, thereby make PNP triode (14 in Fig. 1) conducting, therefore give discrete switching logic circuit supply, and can, with electric weight, not there is not the problem of damage at discrete switching logic circuit at ordinary times.

Three, multi-function jack inserts the mode of taking out holding wire and power line in mobile phone socket, it is convenient to implement, taking-up signal is reliable, do not injure mobile phone body, the structure of multi-function jack as shown in Figure 2, inner patched little electric conductor and formed by multiple, when this socket inserts after mobile phone external socket, these front ends that patch little electric conductor contacts connected with each corresponding points by mobile phone external socket.Rear end is connected with lead-out wire, thereby draws relevant signal.So only pipe mobile phone may have Multiple Type, but by such structure, all can draw required bell signal line, also can add simultaneously and not adopt the required cellular phone power supplies line of mobile phone regular maintenance after battery.

Four, mobile phone and multi-function jack are wrapped vibration damping thing, can avoid having occurred because clash into damage, vibration damping thing can be made by a lot of things, as cotton goods, foamed plastics etc., mobile phone sensing is received after body is wrapped vibration damping thing and packed into together with associated electronic circuits in installation box, form an entirety, be placed within doors to receiving favourable place; Installation box seals, and others can not know the cipher by dialing, and oneself can change easily password, is reliable so maintain secrecy.

After the invention process, there is following outstanding advantage:

Both realized phone and opened the door, and realized again phone and closed the door, what made up that existing a lot of product can not phone closes the door is one large not enough, is mainly manifested in following several respects:

One, coordinating of electronic circuit and mobile phone, excellent performance.Clamshell doors can accurately be recognized with pass gate signal, to the precise control of coding, so it is reliably sensitive again with two functions of opening the door to close the door.

Two, take out signal reliably and conveniently, be not subject to the restriction of mobile phone kind, not destroying mobile phone body, utilance is high, can not carry out secondary operations to mobile phone, and applicability is strong.

Three, level of confidentiality is high, because the password figure place of mobile phone is many, cracked than base is more difficult, and the 2nd, can often change password.

Four, discrete switching logic circuit is reliable, can not produce damage, because at ordinary times, circuit is not charged, only after mobile phone has produced ring, just starts to start.

Five, easy for installation, mobile phone adopts wireless radio transmission network to receive signal, so, place the constraint (as adopted base that the lead-in wire interface constraints of telephone wire will be subject to) that is not subject to environment, do not affect attractive in appearance within doors, also not for its people knows, all bring benefit to maintaining secrecy, relative section is put into box and formed an entirety, strong security.
