Description

The transducer that contains the overvoltage backup

Technical field

The invention belongs to the telecontrol engineering field.

Background technology

With the remote opening door operation of phone realization door, be a kind of fashion of social popularity.The state of the art person of being to use of this series products of existing market calls out the fixed line phone that is placed in the family, by voice suggestion, inputs the password of secondary enabling signal again.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 remedy the deficiencies in the prior art.But it is supporting with it that this patent need a kind ofly receive the transducer of distant signal, and this transducer should meet following requirement:

1, wanting to receive the signal that long distance network is notified from a phone call in electric property, can be the signal of telecommunication that opens the door with the signal transition of notifying from a phone call simultaneously.For not influencing 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 the present automated production of door industry, there is not satisfactory transducer.Consult existing pickoff spare, also do not have a kind of transducer can directly meet above-mentioned 3 requirements.

Realize that this technical scheme requires to mainly contain following difficult point:

1, the kind of moment sensor is a lot, can both 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 that receives is notified from a phone call signal at a distance, changes 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 they are outside output signal directly, all must process again by traditional method, draw signal as the two ends from loudspeaker, but do the integrality that can influence mobile phone like this, and easily cause the damage of mobile phone, also be difficult for producing in batches.

3, mobile phone will be in continuous duty, and mobile phone need be changed battery, in case a little less than the electricity, it is undesired to work, the battery maintenance method of changing by traditional has increased a lot of additional work amounts, is difficult to guarantee that mobile phone can both be in the state of good reception at any time.

If 4 adopt external power supply to replace the mobile phone storage battery, allow the mobile phone long-term work, but now a lot of mobile phones all are to adopt a jack, this jack namely is the external charge jack, it is again the insert earphone jack, and the external charge socket that namely needs required for the present invention needs the jack of call signal again, conflicts.

5, because the starting of reporting to the police is the key element of alarm, whether reliably he directly relate to starting, or malfunction is not arranged.Show after deliberation, address this problem, must work hard simultaneously aspect machinery and two in the circuit, cooperatively interact, the effect that can obtain, but to use what kind of mechanical structure, and what kind of circuit of joining be only best processing method, this also is an important topic that is worth research.

6, invention is a kind of special application product, because its main effect is to realize that phone opens the door, it should be in a kind of armed state at any time, namely is should be in normal operating state at any time, otherwise can not opens the door, directly influence life.Obviously supporting with it with the power supply 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, ordinary electrical home appliance work can only be operated within the common standard, when exceeding standard, damages easily civil power, work and cisco unity malfunction when low, the working range surplus is little, has limited the scope of application of the present invention, the 3rd, the present invention is furnished with storage battery, must carry out the science maintenance, otherwise fragile, the 4th, power supply is flimsy parts in the electrical equipment, in case damage the maintenance difficult of asking someone, and consequence is serious, therefore wants what kind of design, could requirement according to the invention.Also become a difficult problem.Because causing this quality factor of first aspect deficiency 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 when being struck by lightning to surpass this value.Cause the reason of second aspect deficiency to be, 220 volts of civil powers are become bridge rectifier voltage output value after the required low pressure of electronic circuit, can only satisfy city's electric standard of most applications, when the high place of civil power and period, its bridge rectifier output just may be above the amount of imports definite value of three end integrated circuits.For addressing this problem, conventional method is, after bridge rectifier before the three end integrated circuits, increase the one-level emitter follower newly, its objective is, behind the bridge rectifier overtension, allow emitter follower will export pressure limiting, make this not surpass the rated voltage of three end integrated circuits input.Though 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 was low, three end integrated circuits might can be worked, but because there is the additional electrical pressure drop in the emitter follower that increases newly, and three end integrated circuit input ends will step-down, is lower than desirable value, just can not voltage stabilizing.Cause the reason of the third aspect to be, 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 the known designs scheme, being difficult to solve float charge voltage needs high and contradiction that discharge is forced down now.Owing to can not effectively solve the problem of above-mentioned three aspects, so damage easily, this easily produces with regard to having caused next aspect problem, in case namely be to damage, maintenance is difficulty again, influences phone and opens the door, directly influence life.The stabilized voltage power supply of joining in addition, also relates to many-sided problems such as cost cost and reliability.

Because the existence of above-mentioned difficult point, so there is not such product to exist now.

Summary of the invention

5, used triode is high back-pressure large power triode in the supporting power circuit.

6, used diode is face fit type diode in the supporting power circuit.

The relevance of above measure further is explained as follows:

One, the principle of the functional device that opens the door as a kind of phone is, what at first need is to receive the function that phone is called out outside the room, after the calling of phone, just can send the instruction of opening the door outside it receives the room.Mainly to act on be exactly the usefulness that receives mobile phone outside the room (" key " mobile phone) calling to used mobile phone among the present invention.But mobile phone but can not directly be exported the needed signal of telecommunication.This is one, and it two is that present mobile phone many types all are to have only a socket, and this socket had both been made insert earphone socket usefulness, made the usefulness of mobile phone external charge again, and this series products of the present invention needs two external sockets of control signal and charging simultaneously, conflicts.And the present invention proposes the problem that additional mobile phone spininess socket can solve this respect well.

Two, the structure of the additional mobile phone spininess socket among the present invention is shown in figure one, its inside has a lot of positions to patch the little electric conductor that links to each other, after additional mobile phone spininess socket inserted the mobile phone external socket, each exit patched to contact and links to each other in these front ends that patch the little electric conductor that links to each other and the mobile phone external socket.The rear end then is the jack shape, can correspondingly insert a contact pin, and the front end of contact pin inserts in the aperture, and the rear end then connects the outer lead-out wire of socket.Because contact pin can separate with jack, also can patch combination, so can adjust the position in the contact pin place socket behind the line flexibly.Thereby can draw easily and respectively organize data wire in the mobile phone external socket.In the description of back Fig. 1, why each contact pin does not insert little jack, shown that exactly each contact pin can insert the little jack of optional position, this is one, it two is that each contact pin is the same with little jack structure, has shown again from an aspect that also the position that patches of every contact pin is flexible and changeable.Because be such structure, so only manage mobile phone multiple model may be arranged, it is different only to manage the position that the exit of required signal may be in external socket, but the flexible adjustment position by contact pin, all can draw the holding wire of required insert earphone, with mobile phone external charge lead-out wire.And the former introduces control circuit, and the latter then can add mobile phone external charge source.Because the additional mobile phone spininess socket that proposes among the present invention has such structure, so with additional mobile phone spininess socket of usefulness of the present invention, can draw two groups of data wires in the mobile phone easily, and can not damage mobile phone.

Three, the electronics latching circuit has played important function in the present invention, its main effect has 2 points, one of, relaxed the requirement to mobile phone, mobile phone no longer is subjected to the restriction of model, no matter be that the ring size can both be extracted signal reliably, two are sensitivity and the reliabilities that improved emission, the enhanced signal amplification quantity.Its reason one is, because principle of the present invention is, when mobile phone one has signal, will send the warning initiating signal, starts the radio remote-controlled circuit starting immediately, allows receive produce a phone enabling signal; Latching circuit starts immediately, and irretrievable, will send initiating signal.Its reason two is that owing to be security personnel's products, its wireless remotecontrol all is to adopt many yards radiating circuits, needs the regular hour when emission, if without this circuit, in some cases, just might not guarantee the so long time.And this circuit has been arranged, just can guarantee that the emission of starting each time all is very reliable.

As follows to this line description:

One of 1, the form to the pipe amplification that adopts NPN triode and PNP triode to constitute jointly has following meaning,, amplification quantity is big; Two, the PNP triode become saturated after, the loss of voltage of generation little (when being furnished with storage battery, peculiar meaning); Three, can easily transient signal be changed into a kind of long signal; Four, formed electronic switch volume is urinated in miniaturization.

2, in the electronic switching circuit that triode is formed pipe, anti-residual voltage resistance, namely be that the resistance that connects between PNP transistor emitter and the base stage has played important function in circuit, its effect is when NPN triode no signal, the thorough no-voltage of the output of switch, output for the through engineering approaches that electronic switch uses, has been created essential condition without any residual voltage.

3, why between two triodes, add the positive feedback that has the electric capacity differential, the one, satisfy this condition, the 2nd, can realize automatic recovery.

4, why feedback capacity adopts electrodeless reason to be, the electrodeless electric capacity leakage coefficient is little, and at feedback circuit, circuit is more stable under being used for.

Four, because power unit is an emphasis of the present invention, be directly connected to performance of the present invention and reliability, to this circuit, be explained as follows:

The first, measure summation: make 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, is subjected to city's electric control with a PNP triode, to the automatic switchover of floating charge and discharge, make output not produce 1,4 volt drop.

The second, voltage stabilizing circuit pack and the characteristics in the power circuit mainly illustrate:

(1), output voltage can be adjusted into the required normal voltage of floating charge arbitrarily.Its principle is, the voltage-stabiliser tube of article one branch road in the base stage (namely be base stage through road that voltage-stabiliser tube is connected with resistance) 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 partly leading in the electric current of this element.The 3rd, be connected to integrating capacitor between this element and the ground, to avoid the transition of this point voltage; So in this circuit, under the fixed situation of other component parameters, adjust the size of this resistance value, but just pressure regulation, rule is that this resistance value is more high, voltage is more high, otherwise more low.

(2), have voltage stabilizing backup and drop into protection circuit automatically, improved circuit reliability greatly.As everyone knows, active of electronic circuit (namely being triode in the circuit and voltage-stabiliser tube etc.) belongs to easy failed part, this circuit among the present invention, and anti-exactly voltage-stabiliser tube damages and designs.Institute's voltage-stabiliser tube that connects is formed the back and is called for short second branch road between this route base stage and the ground.Its principle is, about base stage saves the low PN of the first branch road pressure drop ratio, second branch road when operate as normal, with the second branch road clamper.So second branch road does not produce " electrical wear ", can not damage.Its meaning is as follows: first, after the voltage stabilizing in first branch road damages in the course of the work, the second branch road voltage-stabiliser tube conducting immediately, though variation has taken place in voltage stabilizing this moment value, many PN joints, (three end integrated circuit circuit, error amount is 0,5 volt), but the voltage of voltage regulation that remains owing to output does not have influence substantially to the electrical equipment of joining.The second, when thunderbolt, first branch voltage increases, and the conducting immediately of second branch road forms shunting, has alleviated the load of first branch road, and first branch road is not fragile, has strengthened the reliability of first branch road.

(3), have three layers of factor protection, so lightning protection is good.The one, used triode is high back-pressure high power valve, and its back-pressure parameter is higher than 78 serial integrated regulators more than 10 times (three end integrated circuits input voltage only is 30 volts); The 2nd, anti-thunder tube is housed.Three be to have voltage stabilizing backup to drop into protection circuit automatically.

(4), the reason that can not damage circuit in the higher place of civil power and period.Adjusting pipe is high inverse-voltage tube, and back-pressure is three ends more than 10 times, will be higher than the integrated regulator of 78 series far away.

(5), can the operate as normal reason on the lower ground of civil power.The one, adjusting pipe because of output voltage is 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 with the bridge rectifier output voltage, namely is as long as bridge-type voltage is 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, if and the input prime of three end integrated circuits string has the triode reflector, then 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 was low, this was valuable voltage).

(6), overcurrent protection principle: when output current was excessive, the resistance drop that output voltage adjustment pipe emitter is connected increased, the diode current flow in the overcurrent protection branch road, base current minimizing, adjusting automatically.

Owing to above reason, so this circuit is compared the many index excellence with 78 traditional serial integrated regulator methods for designing.

Three, the explanation of the floating charge in the power circuit:

This part mainly is made of jointly floating charge resistance, electronic switching tube (PNP triode), 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 big current limitation, the 2nd, realize that the voltage between AC voltage-stabilizing floating charge output point and the storage battery is isolated, thereby when interchange is arranged, namely can float charger, can become working power again.

There is the explanation of the problem of bigger voltage difference when four, scientifically solving the storage battery floating charge with discharge:

Battery tension height when the electronic switch of being made up of PNP triode and peripheral element can successfully solve the storage battery floating charge, and discharge is forced down, both inconsistent problems, its principle is: this pipe base stage resistance to earth is subjected to the control of bridge rectifier output.The composition of this circuit, just formed such principle, when the bridge-type output voltage, having shown has alternating current, storage battery to should be the floating charge stage at this moment, at this moment the operating state of switching tube PNP triode is, its base stage has voltage, and the PNP triode can conducting and become closed state, when when bridge-type output no-voltage, the PNP transistor base does not have auxiliary voltage, and the electronic switch that the PNP triode constitutes becomes opening state.Storage battery is discharge condition.So just distinguish two stages of floating charge and battery discharging reliably.Should heavily point out, this pipe PNP triode not only is a state control switch pipe, floating charge and discharge two states have been distinguished, and the very important point is that storage battery is when being in discharge condition, this pipe is in saturation condition, and the voltage that falls 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 good voltage principle of output quality.

The effect of balance diode assembly: because AC voltage-stabilizing output is float charge voltage 13,5 volts, passed through two diode step-downs after, reduced to again about 12 volts, because the diode dynamic electric resistor 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 a bit be 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 advantage is arranged after the invention process:

1, mobile phone can receive the communication signal of radio net reliably, and when receiving signal, the remote control performance is very good, and the insert earphone signal of telecommunication of output is very reliable.So, very be suitable for the receiving system that opens the door as a kind of phone.

2, mobile phone is a complete integral body, can be used as transducer of the present invention, also can be used as communication handset and independently uses, mobile phone utilance height.Without secondary operations, can not cause the damage of mobile phone with machine.

3, mobile phone receives signal by the wireless radio transmission network, so, place the constraint (will be subjected to the lead-in wire interface constraints of telephone wire as adopting base) that is not subjected to environment, do not influence attractive in appearancely within doors, do not know for its people, to the secret benefit of all bringing yet.

4, strong security, mobile communication password are 11, and often conversion.

5, have very strong operability, practical, it is of a great variety only to manage mobile phone model, but all is suitable for.

6, relax requirement to mobile phone, be not subjected to the restriction of model.

7, enhanced signal amplification quantity makes emission sensitiveer reliable.

8, because the present invention has adopted excellent power supply adapted with it, promoted the performance of integral body of the present invention comprehensively, embodied in the following areas: the one, lightning protection effect is good, and not fragile at thunderstorm season, supporting electrical equipment does not quit work because of thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply wideer adaptive capacity is arranged, namely be work and be unlikely to damage when the high place of civil power and period or accidental cause, and also can operate as normal in voltage lower place and period.The 3rd, can be used for exporting the voltage stabilizing value that there is decimal in generation.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 has overvoltage and overcurrent protection.The 5th, particular importance a bit be no matter at floating charge state, or having a power failure the period, all keeping good performance.
