Description
Technical field
The invention belongs to communication technique field.
Background technology
Realizing the remote opening door operation of door with phone, is a kind of fashion of social popularity.The state of the art of this series products of existing market is that the user calls out the fixed line phone be placed in family, by voice suggestion, then inputs the password of secondary enabling signal.Adopt such technical measures, following 2 deficiencies are arranged, the one, the phone level of confidentiality figure place of opening the door is not high enough; The 2nd, phone has the off-hook program, and the expense that phone opens the door is higher, with often voice suggestion being arranged, the information of bringing out crime is arranged.For this reason, the designer had once applied for a patent, and the enforcement of this patent will make up the deficiencies in the prior art.But this patent needs a kind of receiver supporting with it, and this receiver should meet following requirement:
1, want to receive the signal that long distance network is notified from a phone call on electric property, can change the signal of call into open the door the signal of telecommunication simultaneously.For not affecting the aesthetic feeling of the original decoration of family, so also have following requirement.
2, attractive in appearance, independence is strong, becomes independent parts, in order to supporting.
3, be convenient to place flexibly.
In current automated production, there is no satisfactory receiver in the door industry.Consult existing pickoff part, also do not have a kind of transducer can directly meet above-mentioned 3 requirements and do sensing adapter.
Realize that this technical scheme requires to mainly contain following difficult point:
1, the kind of moment sensor is a lot, can convert a kind of physical quantity to electronic circuit required initiating signal.But, in numerous kinds, but the neither one kind has directly the network received is notified from a phone call to signal at a distance, change the required function that plays dynamic control signal of electronic circuit into.
2, cell phone can receive remote call signal easily from communication network, but it need to change the maintenance of battery, and this is one.It two is that the present invention is a kind of special application product, because its Main Function is to realize that phone opens the door, it should be at any time in a kind of armed state, is should be at any time in normal operating state, otherwise can not opens the door, directly impact life.Obviously supporting with it with the Power Management Design of ordinary electrical home appliance is to be difficult to reach such purpose, its reason one is that ordinary electrical home appliance can not worked when thunderbolt is arranged, can avoid damaging, the 2nd, within ordinary electrical home appliance work can only be operated in common standard, when exceeding standard, easily damages civil power, when low, work and cisco unity malfunction, the working range surplus is little, limited the scope of application of the present invention, the 3rd, the present invention is furnished with storage battery, must carry out scientific maintenance, otherwise fragile, the 4th, power supply is flimsy parts in electrical equipment, once damage the maintenance difficult of asking someone, and consequence is serious, therefore want what kind of design, could requirement according to the invention.Also become a difficult problem.Because causing this quality factor of the deficiency of first aspect is the inherency deficiency of three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series), the voltage of input can not be too high, is generally 30 volts.And have the input of three end integrated circuits while being struck by lightning may surpass this value.Cause the reason of which aspect deficiency to be, 220 volts of civil powers are become to the bridge rectifier voltage output value after the required low pressure of electronic circuit, can only meet city's electric standard of most applications, at civil power, when high place and period, its bridge rectifier output just may be over the amount of imports definite value of three end integrated circuits.For addressing this problem, conventional method is, after bridge rectifier before three end integrated circuits, newly increase the one-level emitter follower, its objective is, after the bridge rectifier overtension, allow emitter follower will export pressure limiting, make this not surpass the rated voltage of three end integrated circuit inputs.Although such scheme has been expanded the higher limit of bridge rectifier output, but has produced new contradiction, because newly-increased emitter follower can produce the supplementary loss voltage drop.When civil power is low, three end integrated circuits likely can be worked, but because there is the additional electrical pressure drop in newly-increased emitter follower, and three end integrated circuit input ends will step-down, lower than desirable value, and just can not voltage stabilizing.The reason caused is, because the output valve of circuit of three-terminal voltage-stabilizing integrated is a certain integer value of fixing, as, 5 volts, 8 volts, 12 volts, the float charge voltage of the fractional value of can't satisfying the demand, as 3.7 volts, 12.6 volts, etc.More seriously, in present existing design, be difficult to solving float charge voltage needs high and contradiction that electric discharge is forced down.Due to the problem that can not effectively solve above-mentioned three aspects, so easily damage, this has just caused next aspect problem easily to produce, once be to damage, maintenance is difficulty again, affects phone and opens the door, directly impact life.The stabilized voltage power supply of joining in addition, also relates to many-sided problems such as cost and reliability.
Summary of the invention
The objective of the invention is to design a kind of applicable receiver, be mainly used in the automated production of supporting door industry, the one, the patent that the designer is applied for, do further to supplement.Two are to provide a kind of transducer kind of excellence, and the outstanding product of exploitation door industry class provides larger space.
Concrete measure of the present invention is:
1, precisely signal receiving device is by the signal mobile phone, supporting power supply, the common composition.
Wherein: the signal mobile phone is on loudspeaker two pile crowns with an end interconnection network mobile phone of one group of wire, and the other end is as the export-oriented output of signal.
The two ends that connect the charge power supply of mobile phone with an end of another group wire, the other end is connected on mobile phone and safeguards in power supply output.
Supporting power supply is by AC voltage-stabilizing circuit, floating charge circuit, and the accumulator cell charging and discharging switching circuit, the combined balance system circuit forms jointly.
AC voltage-stabilizing circuit is: alternating current has been exported 4 tunnels after over commutation; The one, and be connected an anti-thunder tube between ground wire; The 2nd, and be connected an electric capacity between ground; The 3rd, having connected a triode is the collector electrode that output voltage is adjusted pipe; The 4th, connected an end of a resistance; The other end of this resistance has connected the base stage of output voltage adjustment pipe.
The base stage that output voltage is adjusted pipe has connected three branch roads; The one, the reference voltage branch road, this branch road is the positive pole that base stage has connected a voltage-stabiliser tube, the negative pole of this voltage-stabiliser tube grounding through resistance of having connected; The 2nd, the backup protection branch road, this branch road is to have connected the positive pole of another voltage-stabiliser tube, the minus earth of this voltage-stabiliser tube in the base stage of output voltage adjustment pipe; Three is capacitance cathodes, this electric capacity minus earth.
Terminated at the emitter of output voltage adjustment pipe with a resistance one, the other end is as the output point of voltage stabilizing circuit float charge voltage; With two diode series connection, one of diode cathode has terminated at the base stage of adjusting pipe, and the other end is connected on the output point of the emitter float charge voltage of adjusting the stream organ pipe.
With a resistance, with diode, connect, diode cathode has terminated at the float charge voltage output point of voltage stabilizing circuit, diode cathode terminates at the contact of connecting of voltage-stabiliser tube and resistance in the first branch road, and this contact has also connected the positive pole of an electric capacity, this electric capacity minus earth.
Floating charge circuit is: with a resistance, be that one of floating charge isolation resistance has terminated at the float charge voltage output point, the other end has been connected on the positive pole of storage battery.
The accumulator cell charging and discharging switching circuit is: having connect a PNP triode at the positive pole of storage battery is the emitter that discharges and recharges electronic switch, has terminated at the base stage of this triode with one of a resistance, the other end ground connection of resistance; Be connected to rectification output with a positive pole of controlling diode, its negative pole end has been connected to the base stage that discharges and recharges electronic switch, and the collector electrode that discharges and recharges electronic switch has been connected on alternating current-direct current mixed voltage circuit output point.
The output of combined balance system circuit is: the output point of float charge voltage becomes alternating current-direct current mixed voltage circuit output point after two diode series connection, and this point is also the final output point of circuit of the present invention.
2, in supporting power supply, the isolation resistance of floating charge circuit can replace with triode.
3, in supporting power supply, the isolation resistance of floating charge circuit replaces with triode, and this triode is high back-pressure high power valve, as 3DD15.
4, the anti-thunder tube puncture voltage parameter value that the output of the rectification in supporting power supply is welded is below 100 volts.
5, the first branch road that connected voltage-stabiliser tube is connected with resistance over the ground of the output voltage adjustment pipe base stage in supporting power supply, voltage-stabiliser tube power is for being greater than 1/2nd watts, and resistance is for being greater than 1/2nd watts.
The relevance of above measure further is explained as follows:
The principle of the functional device one, opened the door as a kind of phone is that what at first to need is to receive the function that outside room, phone is called out, and outside it receives room, after the calling of phone, just can send the instruction of opening the door.In the present invention, mobile phone Main Function used is to be used as to receive mobile phone (" key " mobile phone) calling outside room.While calling out due to mobile phone outside room, receiver ring of the present invention rings within doors, and signal is directly drawn by mobile phone self loudspeaker, so receive signal, is reliably, also can not produce the loss of signal.
If two only use the signal mobile phone as receiving network signal, but do not have excellent mobile phone to safeguard power supply, can't become the product that can receive on a kind of engineering, more can not become the product that a kind of excellent performance is good, because mobile phone needs normal battery to safeguard, if the employing Alternating Current Power Supply, also essential will in the situation that multiple severe can normal operation, so the power supply of safeguarding of mobile phone becomes a key component of the present invention.
Three, because power unit is an emphasis of the present invention, be directly connected to performance and reliability of the present invention, to this circuit, be explained as follows:
The first, measure summation: made the modified model of emitter follower by one of them NPN triode, the float charge voltage of output science; The power supply of work system is provided when civil power is arranged simultaneously, with a PNP triode, is subject to city's electric control, to the automatic switchover of floating charge and electric discharge, make output not produce the drop of 1.4 volts.
The second, voltage stabilizing circuit pack and the characteristics in power circuit mainly illustrate:
(1), output voltage can be adjusted into arbitrarily the required normal voltage of floating charge.Its principle is, the voltage-stabiliser tube of article one branch road in base stage (being the base stage road in series with a resistor through voltage-stabiliser tube) can be realized the coarse adjustment of output voltage, and resistance can be realized accurate adjustment.It should be noted that, why resistance can realize that the reason one of accurate adjustment is that the ratio that accounts for of the pressure drop of this resistance is little, the 2nd, designed output end of pressure-stabilizing and provide electric current by this resistance of Zhi Luxiang of diode and resistance string, and this branch current accounts for leading part in the electric current of this element.The 3rd, be connected to integrating capacitor between this element and ground, to avoid the transition of this point voltage; So in the fixed situation of other component parameters, adjust the size of this resistance value in this circuit, with regard to pressure-adjustable, rule is that this resistance value is higher, and voltage is higher, otherwise lower.
(2), there is voltage stabilizing backup and automatically drop into protection circuit, greatly improved circuit reliability.As everyone knows, active of electronic circuit (being triode in circuit and voltage-stabiliser tube etc.) belongs to easy failed part, this circuit in the present invention, and anti-exactly voltage-stabiliser tube damages and designs.Between this route base stage and ground, institute's voltage-stabiliser tube that connects is called for short the second branch road after forming.Its principle is that base stage is to the low PN joint of first branch road pressure drop ratio the second branch road left and right, by the second branch road clamper when normal operation.So the second branch road does not produce " electrical wear ", can not damage.Its meaning is as follows: the one, after the voltage stabilizing in the first branch road damages in the course of the work, the second branch road voltage-stabiliser tube conducting immediately, although variation has occurred in now voltage stabilizing value, many PN joints, (three end integrated circuit circuit, error amount is 0.5 volt), but due to output remain voltage of voltage regulation, on joined electrical equipment substantially without affecting.The 2nd, when thunderbolt is arranged, the first branch voltage increases, and the conducting immediately of the second branch road forms shunting, has alleviated the load of the first branch road, and the first branch road is not fragile, has strengthened the reliability of the first branch road.
(3), there are three layers of factor protection, so lightning protection is good.The one, triode used is high back-pressure high power valve, and its back-pressure parameter is (three end integrated circuits input voltages are only 30 volts) higher than 78 serial integrated regulators more than 10 times; The 2nd, anti-thunder tube is housed.Three be to there is voltage stabilizing backup automatically to drop into protection circuit.
(4), at civil power, higher place and the period can not damaged the reason of circuit.Adjusting pipe is high inverse-voltage tube, and back-pressure is three ends more than 10 times, by far away higher than the integrated regulator of 78 series.
(5), the lower ground reason that can work at civil power.The one, because adjusting pipe, be high inverse-voltage tube, can design the bridge-type output voltage higherly, just can do certain compensation when civil power is low.The 2nd, output voltage adjustment pipe of the present invention, can not produce the additional electrical pressure drop, and it directly is adjusted into electric power output voltage by the bridge rectifier output voltage, be to need only bridge-type voltage higher than output voltage, and this voltage can make triode work, just energy voltage stabilizing.(illustrate: if the design that adopts traditional triode to connect with three end integrated circuits, so work that three end integrated circuits will be stable, voltage that just must input is higher than definite value of output, and if the input prime of three end integrated circuits string has the triode reflector, input has just increased the auxiliary voltage loss that emitter follower causes, that is to say when civil power is low, after bridge-type output must deduct supplementary loss voltage, be only the input effective voltage of three end integrated circuits.And, when civil power is low, this is valuable voltage).
(6), overcurrent protection principle: when output current is excessive, adjust the resistance drop increase that the pipe emitter is connected, the diode current flow in the overcurrent protection branch road, base current minimizing, the automatic adjusting.
Due to above reason, thus this circuit with 78 traditional serial integrated regulator methods for designing, compare, the many index excellence.
Three, the explanation of the floating charge in power circuit:
This part mainly consists of jointly floating charge resistance, electronic switching tube (PNP pipe), peripheral assembly and balance diode.
Because the NPN triode has been exported the floating charge normal voltage, so the floating charge science.Floating charge resistance mainly contains two functions, and the one, to large current limitation, the 2nd, realize the voltage isolation between AC voltage-stabilizing floating charge output point and storage battery, thereby when interchange is arranged, can floating charge, can become operation source again.
There is the explanation of the problem of larger voltage difference while four, scientifically solving the storage battery floating charge with electric discharge:
When the electronic switch be comprised of PNP triode and peripheral element can successfully solve the storage battery floating charge, battery tension is high, and electric discharge is forced down, both inconsistence problems, and its principle is: this pipe base stage resistance to earth is subject to the control of bridge rectifier output.The composition of this circuit, just formed such principle, when the bridge-type output voltage, shown now to have alternating current, storage battery to should be the floating charge stage, at this moment the operating state of switching tube PNP pipe is, its base stage has voltage, and PNP pipe can conducting and become closed state, when when bridge-type is exported no-voltage, PNP pipe base stage does not have auxiliary voltage, and the electronic switch that the PNP pipe forms becomes opening state.Storage battery is discharge condition.So just distinguish reliably two stages of floating charge and battery discharging.Should heavily point out, this pipe PNP pipe is not only a state control switch pipe, has distinguished floating charge and electric discharge two states, and the very important point is that storage battery is when discharge condition, this pipe is in saturation condition, and the voltage fallen is very low, can not lose the most valuable pressure drop of storage battery.
Five, alterating and direct current is mixed the explanation of the voltage principle that output quality is good:
The effect of balance diode assembly: because AC voltage-stabilizing output is 13.5 volts of float charge voltages, through after two diode step-downs, reduced to again about 12 volts, because dynamic resistance of diode is little, little to load effect, do not produce the output voltage fluctuation, so guaranteed to exchange the correctness of output.And, when storage battery power supply, without this part, only through discharging and recharging electronic switch, do not produce pressure drop.
With regard to power supply, this beyond above-mentioned multiple performance, this power supply also has core be a bit active few, thereby bring reliable, cost is low, circuit is simple and easy to produce a series of advantages such as easy debugging.
Following outstanding advantages is arranged after the invention process:
One, mobile phone can receive the signal of wireless communication networks reliably, and anti-interference strong, and this is because no matter be that extraneous acoustic jamming or electrical interference all can not make sound horn, produces the malfunction signal.Extremely be suitable as the receiving system that a kind of phone opens the door.
Two, mobile phone receives signal by the wireless radio transmission network, so, place the constraint (as adopted base, will be subject to the lead-in wire interface constraints of telephone wire) that is not subject to environment, do not affect attractive in appearancely within doors, for its people, do not know, to the secret benefit of all bringing yet.
Three, strong security, the one, cell phone password is 11, the 2nd, can change at any time.
Four, because the present invention has adopted excellent power supply adapted with it, General Promotion the performance of integral body of the present invention, embody in the following areas: the one, lightning protection effect is good, at thunderstorm season, not fragile, supporting electrical equipment does not quit work because of thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply, wider adaptive capacity is arranged, work while being the place high at civil power and period or accidental cause and be unlikely to damage, and lower place and the period also can work at voltage.The 3rd, can be used for output for the voltage stabilizing value that decimal is arranged.Thereby can the required voltage of floating cell.Storage battery is not fragile, and the life-span is long.The 4th, simple in circuits is easily gone, and excellent performance, have overvoltage and overcurrent protection.The 5th, particular importance be a bit no matter at floating charge state, or, having a power failure the period, all keeping good performance.
Five, because supporting power supply can be adjusted output voltage flexibly, thus can be unrestricted as the kind of signal mobile phone, so this bright exploitativeness is strong.
