4,, after multi-function jack inserts in the socket of mobile phone, refill in installation box after superscribing vibration damping thing.
5, discrete switching logic circuit is to be screwed in installation box.
As follows to further illustrating of above measure:
One, the principle that phone of the present invention opens the door is, operator calls out the present invention with phone without, the present invention receives after bell signal, produce into the signal of telecommunication through the conversion of transducer, then carry out logic transition through electronic circuit of the present invention, " length " in when operation and " short " signal can be transformed into the wireless remotecontrol of closing the door or opening the door and transmit, when the actuator in door receives after remote control command, then carry out relevant logical action.
Two, discrete switching logic circuit in measure can be differentiated the principle process of closing the door with enabling signal automatically: 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 in discrete switching logic circuit and carry out logic transition, the bell signal taking out is after interface unit (2 in Fig. 3), what first enter is the resistance (8 in Fig. 3) closing in door, this is owing to there being an integrating capacitor (4 in Fig. 3) to need charging in the passage that opens the door, integrating resistor (3 in Fig. 3) 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 circuit, 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. 3 3) and integrating capacitor (4 in Fig. 3), first inverter (5 in Fig. 3) in the passage that opens the door, the output of first inverter plays two aspects, the one, after second inverter (6 in Fig. 3) opening the door in passage, again export positive signal, connect the bit line of the integrated circuit of encoding in multi-code transmitter circuit, the signal that now remote control is sent is enabling signal, the 2nd, through the signal of clamp diode (9 in Fig. 3) clamper pass door, because this point and the input of closing in door have isolation resistance (8 in Fig. 3), 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.
Three, the 14PNP triode in 12NPN triode and the Fig. 3 in Fig. 3 has formed switching circuit, when mobile phone has had bell signal, base resistance through NPN triode starts NPN triode, thereby make the conducting of PNP triode, 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.
Four, multi-code transmitter circuit has played critical effect in the present invention, and main benefit is to be difficult for producing malfunction.Use now the apparatus of remote control many, as locking that car door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the many yards of artificial disturbances that just can thoroughly stop afterwards this class.Have after multi-code transmitter circuit, greatly improved confidence level of the present invention.
The principle that realizes multi-code transmitter is; In the time that the first end of programme control circut is exported a high position, it is low that the inverter output connecting makes the chip select of this coding integrated circuit of connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner only have corresponding section's chip select work.The 3rd, the 4th reason is the same.Due to each coding integrated circuit with or a door mode be input to modulating tube, so form the form of multi-code transmitter.
Five, 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 4, 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.
Six, 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.
Seven, constantly development is with universal for science and technology, and electronic product has spreaded all over each family, electronic product, all need an outstanding power supply supporting with it, the performance that guarantee electronic product is outstanding, is therefore further explained the voltage stabilizing circuit of power supply:
(1), the cardinal principle of voltage stabilizing:
Jointly form voltage stabilizing adjustment unit by inclined to one side resistance (104 in Fig. 1), adjustment diode (107 in Fig. 1) in adjustment triode (103 in Fig. 1), voltage adjustment with the voltage adjustment branch road that accurate adjustment resistance (106 in Fig. 1) forms.
Adjusting triode is high back-pressure large power triode, reverse breakdown voltage is greater than 100V, the form with output is penetrated in employing, negative feedback is strong, after once the parameter of voltage adjustment branch road is determined, just output is for a definite value to adjust triode, and this definite value can meet the floating charge requirement of electronic DC switch circuit.
(2), there is good overcurrent protection and the explanation of Monitoring Performance:
This unit shows that by overcurrent protection resistance (108 in Fig. 1), overcurrent protection triode (109 in Fig. 1), overcurrent luminous tube (110 in Fig. 1) forms.
Produce the principle of overcurrent protection: (normally the electronic component in equipment damages when corollary equipment breaks down; make the overall current excessive); now increase through the electric current of overcurrent protection resistance; exceed after the voltage between overcurrent protection transistor emitter and base stage, overcurrent protection triode is open-minded, forms the base bleeder current to the adjustment triode in voltage stabilizing adjustment unit; the output of triode is adjusted in sealing; now overcurrent shows that luminous tube is luminous, observes, in time handling failure for people.
There is automatic protection and automatic restorability: when overcurrent protective resistance voltage increases, overcurrent protection triode is open-minded, after Failure elimination, automatically recovers.
(3), there is the explanation of good overvoltage protection ability:
This unit is made up of anti-thunder tube (102 in Fig. 1), voltage-limiting protection branch road (105 in Fig. 1), overvoltage protection controllable silicon (113 in Fig. 1), triggering voltage-stabiliser tube (111 in Fig. 1), control electrode resistance (112 in Fig. 1).
For at thunderstorm season, various electronic equipments again power-off ensure that it can not damage, and can normally work, and therefore lightning protection and overvoltage are keys.For lightning protection and anti-overvoltage, the present invention has made following measures:
1, overvoltage protection controllable silicon has formed fast tripping protection function, has very strong anti-overvoltage capabilities.
The principle forming: cause the output end voltage of voltage stabilizing adjustment unit too high when thunderbolt; and exceed after the voltage stabilizing value that triggers voltage-stabiliser tube, trigger overvoltage protection controlled silicon conducting, immediately to adjusting the base stage clamper of triode; to adjusting the sealing of triode output voltage, form the fast tripping protection of lightning protection overvoltage.
Overvoltage protection scr promoter is rapid; can also recover voluntarily, its reason is: the output end voltage once voltage stabilizing adjustment unit is too high, and overvoltage protection controlled silicon conducting has very strong positive feedback; can, rapidly by adjusting the base stage clamper of triode, form " fast tripping protection function ".And after the output of voltage stabilizing adjustment unit is without overvoltage, can not overvoltage protection controllable silicon be formed and be triggered, there is " door " because trigger voltage-stabiliser tube, thereby become one of reason that overvoltage protection controllable silicon automatically recovers, two are resistance to earth of the overvoltage protection SCR control utmost point, form shunting, greatly reduce the self-sustaining sensitivity of overvoltage protection controllable silicon, theory and test explanation, as long as it is proper that this resistance is adjusted, once overvoltage disappears, overvoltage protection controllable silicon will exist without self-sustaining electric current, and automatically revert to off state, if be again struck by lightning, again start, form protection, until output voltage is normal value, in the time of overvoltage not, overvoltage protection controllable silicon is in " open-circuit condition ", as long as just work when thunderbolt or overvoltage, so be not easy to damage, moment is all in a kind of " backup " guard mode, strengthen the reliability of protection.
2, there is voltage-limiting protection branch road, be connected on voltage and adjust in branch road, in the time having thunderbolt overvoltage, to adjusting the base stage voltage stabilizing of triode, form the voltage-limiting protection of the output to voltage stabilizing adjustment unit again.This branch road is adjusted many four of the diode of branch road than voltage, to adjust the voltage of branch road high for the voltage ratio voltage of voltage-limiting protection branch road, and therefore in the time of overvoltage not, voltage-limiting protection branch road can conducting, is Status of Backups, can not produce electrical wear.And used be diode, more durable than common voltage-stabiliser tube, so not fragile.
3, be equipped with anti-thunder tube, the withstand voltage of anti-thunder tube is lower than the reverse breakdown value of adjusting triode, and therefore, in the time having thunderbolt overvoltage, anti-thunder tube preferentially disconnects, and has protected the entirety of power supply.
4, adjusting triode is high back-pressure large power triode, and reverse breakdown pressure value, higher than 100V, exceeds 10 times than three conventional end integrated stable voltage circuits, so overvoltage is had remarkable power of endurance.
(4), the explanation of electronic DC switch circuit:
The electronic DC switch circuit being formed by charging resistor (115 in Fig. 1), electric discharge electronic switching tube (117 in Fig. 1), storage battery (116 in Fig. 1), rectification control diode (118 in Fig. 1), base stage controlled resistor (119 in Fig. 1), realize science floating charge, solve the high and problem that discharge voltage is low of charging voltage, can not produce pressure drop in battery discharging, reduce the loss of voltage, formed sharing of alternating current-direct current.
1, the reason of energy standard floating charge:
The accurate adjustment resistance that adjustment transistor base adjustment diode is gone here and there can carry out voltage adjustment within 0.7V, is easy to adjust standard float charge voltage 13.8V.
2, solution float charge voltage is high, and the low principle of discharge voltage:
(1), electric discharge electronic switching tube is high-power PNP triode, when base voltage low, the conducting of PNP triode, one large electric current flows to collector electrode from the emitter of PNP triode, collector voltage raises, therefore in the time of rectification output no-voltage, the conducting of electric discharge electronic switching tube, be that storage battery starts electric discharge, why select PNP triode, because pressure drop is very little, negligible when its conducting, so can not produce pressure drop in without alternating current, the collector voltage of discharge diode is equal to battery tension.
(2) and in the time having alternating voltage, the base stage of discharge diode directly inputted voltage by rectification control diode, because the characteristic of PNP triode, base stage has voltage to exist, therefore discharging electronic switching tube can conducting, so electric discharge electronic switching tube is at ordinary times in cut-off state.
(5), the use of balance diode (120 in Fig. 1), in the time having Alternating Current Power Supply, allow the output end voltage of voltage stabilizing adjustment unit reduce to available operating voltage, and in the time only having DC-voltage supply, direct voltage is without balance diode, can not produce unnecessary pressure drop, realize alternating current-direct current and share.
(6), can be in the main cause of the lower place of civil power and period work: the one, the pressure regulation triode in circuit, can not produce additional electrical pressure drop, as long as commutating voltage higher than output voltage, just can allow this pipe work, just energy voltage stabilizing.(illustrate: if the input voltage expansion scheme that adopts traditional triode to connect with three end integrated circuits, the three end integrated circuits required voltage of normally working must be provided, also need triode operating voltage, main product has been given birth to triode supplementary loss voltage so simultaneously.And in the time that civil power is low, this is valuable voltage).It two is to be high inverse-voltage tube because adjusting triode, so time can rectifier output voltage can be designed higherly in design, in the time that civil power is low, at this moment commutating voltage be can not output very low, just can do certain compensation.
Can expand the explanation of civil power excursion: because civil power does not damage circuit when high, and still can normally work when lower.So expanded the working range that civil power changes.
Eight, mobile phone voltage matches device is that voltage stabilizing forms on the basis in alternating current-direct current lightning protection source, adjusts very easily the needed supply voltage of mobile phone, and circuit is simple, easy to adjust, is used on other power supply also very applicable.
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, the multi-functional voltage stabilizing circuit of adapted has following advantage: 1, stable voltage can be provided, have again monitoring effect, have fault if institute arranges, initiatively warning immediately, fault-free is not indicated, and fault disappears, stand and both recovered, so more supporting special electronic equipments, meaning is very large.
2, lightning protection and overvoltage capabilities are strong, have multiple lightning protection anti-over voltage function, no longer because thunderstorm season power-off quits work.
?3, adapt to wide, high at the voltage that meets accident, can not damage.And also can normally work in the lower place of voltage and period, expand the scope of city's electro-mechanical wave.
4,, there is the voltage stabilizing value of decimal in available adjustment output generation, to the floating charge of storage battery science.There is overcurrent protection simultaneously.Be fruitful or other electronic products have excellent performance after supporting.
5, simple in circuits, easily produces and debugging.
Two, excellent performance, mobile phone can receive the communication signal of radio net reliably, while receiving signal, the vibrating effect that it sends, excited vibration transducer is reliable, and vibrating sensor is output electrical signals reliably, so remote-control receiver electric property is very good, extremely be suitable for the receiving system opening the door as a kind of phone, open the door sensitive and reliable with the function of closing the door, also can be used as other long-distance remote control simultaneously.
Three, mobile phone is a complete entirety, can make the reception part of signal transducer, also can be used as mobile phone and independently uses, and mobile phone utilance is high.To using mobile phone without secondary operations, can not cause the damage of mobile phone simultaneously.
Four, 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.
Five, 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.
Six, 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.
Seven, between transmitting and reception, can realize and mating well, greatly promote distance between the two.Between radio ttransmitter and receiver, have good effect, receiving unit can be put more hiddenly, and laying of being in a little brought to more selection, simultaneously also can be to the secret space that provides is a little provided.
Eight, mobile phone no longer needs to change battery, reduce because changing the trouble brought of battery, and damage to mobile phone.
