Description

Security personnel field transducer

Technical field

The invention belongs to the safety technique field.

Background technology

With the remote opening door operation of phone realization door, be a kind of upsurge 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 of family, takes out the remote signal of opening the door from fixed line phone.Adopt such technical measures, following 3 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, thereby the expense that phone opens the door is higher.The 3rd, voice suggestion is arranged more, outwards passed on and brought out the crime signal.For this reason, the designer had once applied for a patent, and the enforcement of this patent will remedy the deficiency of existing product.But this patent needs a kind of remote control head that receive distant signal supporting with it, and this receiving system should meet can receive remote signal of notifying from a phone call on electric property, and the while can be the requirement of the signal of telecommunication that opens the door with the signal transition of call.For not influencing the aesthetic feeling of the original decoration of family, receiving system is not only attractive in appearance, and independence is strong, becomes independent parts, also will be convenient to place flexibly, and is easily supporting with the control board that is cooperated.

In the present automated production of door industry, there is not satisfactory receiving system.There is not a kind of receiving system directly to meet above-mentioned 3 requirements without innovation yet.

Realize that this technical scheme mainly contains following difficult point:

1, the kind of dynamo-electric receiving system is a lot, it all is the good device that can convert a kind of physical quantity to a kind of ultra-weak electronic signal, but in the middle of numerous kinds, but not having a kind of is to change the device of signal of telecommunication kind into directly the remote call signal that receives.

2, cell phone and fixedly base can from communication network, receive remote call signal easily, but they all can not make receiving system usefulness because they all can not directly outwards export the signal of telecommunication.Want outside output signal, all must process once more by traditional method, the relevant point in is drawn signal internally, but this do the integrality that can influence complete machine, especially easily cause the damage of mobile phone.

So, the effective ways of dealing with problems are, form a kind of new receiving system with existing device, form first part of new receiving system with receiving remote communication device such as cell phone, and with another kind of receiving system as the new composite received device of the present invention second partly, promptly second portion is converted into output signal again with remote signal again.But this forms new composite received device following specific requirement is arranged again.

3, adopt the combination of which type of Communication Equipment and which type of receiving system spare, just can make the preceding part of received signal and the rear section of output signal realize the coupling of signal transmission science.Signal is lost little relatively, thereby makes the electric property of new composite received device the most reliable and stable.

4, adopt the new receiving system of what carrier combinations two partly, reliable, integral body is attractive in appearance relatively, volume is less.

5, owing to mobile phone model and in many styles, the jack disunity, mobile phone will be used external power supply, is difficult to implement with unified method.

6, mobile phone model difference, the size of vibration intensity are also just different, and signal is not each time lost, and make signal each time can both become useful signal, and this also is a problem that is worth research.

7, present senior product often has (maybe must have) wireless link link, and the radio transmission product mainly is to adopt the solid size radiating circuit emission that coding is arranged now, this is feasible for general household electrical appliances, but can not satisfy the requirement of precision for the product of higher gears, not only because social now upward wireless remotecontrol has been widely used in various fields, the lock of locking as automobile burglar all will use remote control, and these all becomes wide interference source.Also there is artificial instrument interference and cracks.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to serial problems such as cost again, therefore encodes with which type of and realizes thoroughly stopping all interference in the society, and reach the low again purpose of cost, also becomes a difficult problem.

8, the inventor has had multinomial electronic technology achievement, belongs to security personnel's equipment class, all needs a kind of stabilized voltage power supply preferably supporting with it, if but present circuit of three-terminal voltage-stabilizing integrated without transformation directly application can not reach effect preferably.Its main cause one is that the lightning protection grade is not high, and the equipment of ensuring public security like this will may damage in thunderstorm season, or cisco unity malfunction, will cause the protector serious period out of control.The 2nd, can not in the very wide scope of civil power, work, directly influenced the range of application of security personnel's equipment.The 3rd, voltage stabilizing numerical value can not be transferred to the voltage stabilizing value of decimal neatly, as 3.7 volts, 12.7 volts.Cause a major reason of above 3 deficiencies to be that the inherency of the three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series) in the electronic product causes, the voltage of 78 serial integrated regulator inputs 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.So caused the deficiency of first aspect.Cause the reason of the deficiency of second aspect to be, also because the input voltage rated value of three ends is not high, so the design of the secondary low-voltage side output voltage of transformer is restricted.In present traditional design, though proposed the scheme of triode and three end co-design, but produced new contradiction again, owing to increased easy failed part voltage stabilizing didoe, this just may produce the negative sense result of two aspects, and the one, reliability is affected, and the 2nd, lightning protection effect is affected, 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, can't the satisfy the demand float charge voltage of fractional value is as 12,6 volts, etc., also inconvenient when adjusting its voltage stabilizing value, promptly be unfavorable for producing in batches.

In addition, the stabilized voltage power supply of being joined also relates to many-sided constraints such as cost cost and reliability, so required stabilized voltage power supply is simple at first sight, but anatomizes, but many places difficult point, also further innovation abrim.

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

9, used diode is a heavy-duty diode in the rectification circuit.

The relevance of above measure further is explained as follows:

1, the principle as the functional device of a kind of phone start is that what at first to need is the function that can receive the phone calling room outside, 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.Therefore the remote control among the present invention receives head and must have two kinds of functions, and first kind of function is the calling that can receive the telephone set room outside, second kind of function be will calling acoustical signal be converted into the signal of telecommunication of output once more.

2, mobile phone itself has receiving function, and the acoustical signal of calling out is converted into the output signal of telecommunication, and the present invention has adopted the conversion of vibration receiving system.Concrete measure is that the vibration receiving system is fixed on the mobile phone, after mobile phone has had call signal, will become a kind of vibration source, at this moment vibrates receiving system and will be converted into the signal of telecommunication to the acoustic vibration signal and outwards export.This signal of telecommunication can be introduced in the control circuit.Therefore mobile phone is through after such processing, and its science is that common mobile phone can realize becoming a kind of can the reception and the special-purpose sensing receiving system of exportable remote control, and this is an one.It two is to solve only jack of mobile phone, and the present invention needs the contradiction of external power supply and two jacks that take out call signal, and it three is not to be subjected to the restriction of mobile phone model and to influence its structure.

3, piezoelectric ceramic piece is good microphone device, and when the two poles of the earth at them added audio telecom, this sheet can sounding.Test shows: also can be with its inverting function as a kind of vibration receiving system.That is to say that the faint signal of telecommunication can be exported in the two poles of the earth of potsherd when adding vibration signal at their the two poles of the earth.If it is fixed on the mobile phone, mobile phone is received signal because sound and vibration are arranged, so just can become a kind of vibration source, allows the two poles of the earth of piezoelectric ceramic piece export sensing telecommunications.Potsherd is thin, and area is less not fragile, and is easily fixing, in the vibration receiving system in, specification requirement more according to the invention.And present following benefit, and the one, when vibration is converted into the signal of telecommunication, reliable.The 2nd, though the mobile phone kind is numerous, what have has a receiver J-Horner, the earless machine transplanting of rice mouth that has, though have receiver J-Horner arranged, the receiver J-Horner shape is difficult to unified, and after adopting measure of the present invention, can both take out the signal that mobile phone is received with same procedure.The 3rd, easy to operate, as long as piezoelectric ceramic piece is tightly glued on the mobile phone, do not destroy mobile phone integral body fully with glue.The 4th, anti-interference strong, because piezoelectric ceramic piece tightly is bonded on the mobile phone, must mobile phone continuous shaking just can touch piezoelectric ceramic piece output.So an extraneous interference is not easy to make its to trigger.After the mobile phone integral body that is fixed with piezoelectric ceramic piece being wrapped vibration damping thing such as towel, it is few to minimum the interference in the external world can be slowed down.

4, repetition test explanation is in case after piezoelectric ceramic piece has had additional message box, when the signal of sound vibration is converted into the signal of telecommunication, can improve very big performance.The structure of piezoelectric ceramic piece and the combination of additional message box is shown in figure one and figure two.Piezoelectric ceramic piece is formed the two poles of the earth by two faces.One of them bigger face is a utmost point, and another less face is another utmost point.Holding wire is drawn from the two poles of the earth respectively, and when vibration signal passes on the sheet, its lead-in wire will be exported corresponding ultra-weak electronic signal.Additional message box then is to fix with bigger one side, and both also keep certain interval.Have an aperture at the positive center of message box, during as vibration receiving system of the present invention, this hole is the optimum of source of sound input.Because additional message box arranged, so in case when having sound source to pass to piezoelectric ceramic piece, the sympathetic response effect is arranged, so can improve the output energy of the signal of telecommunication.

5, because the enforcement of vibration damping thing; improved anti-jamming capacity greatly; therefore incapability is placed on the present invention within doors or vibrates in the bigger door; do not influence its effect; after doing pouch with textile; the favorable damping effect is not only arranged, and very convenient when implementing, also can protect the mobile phone surface.

6, among the present invention, the timing feedback circuit plays an important role to the signal reliability among the present invention, have only and adopted it original bell signal could be become reliable control signal, could be operational discreteness, the discreteness of type, and the discreteness of switch, become a kind of unified reliable signal.So stress below must doing:

(1), the meaning of timing feedback circuit: one of after the present invention receives bell signal, it or not final purpose, final purpose is to remove to promote the wireless remotecontrol radiating circuit with bell signal, make it to send the initiating signal of wireless remotecontrol emission, then make supporting performer after receiving remote signal, move, (being fruitful as the inventor is antitheft door, be to allow the power set that open the door of door start) so, how bell signal reliably promotes radio transmitter circuit, be an important technology key, its reason is because mobile phone is of a great variety, and the ring that has is an on-off state, has plenty of continuous state, the signal that has is strong, a little less than the signal that has, if there is not a kind of good timing feedback circuit, be difficult to guarantee reliability of products, and adaptability is widely arranged.Two because the timing feedback circuit has been arranged,, be widely so the mobile phone that is adapted to is not limited by the requirement of mobile phone model can, this is an one; It two is that the present invention receives to adopt behind the signal radio transmission and execution unit to get in touch, and any execution unit can add receiving system and realize mating with the present invention, so execution unit that can be supporting also is widely.

(2), the operating principle of timing feedback circuit: when not receiving signal, first transistor collector is high-order, and the current collection of second triode is very low, not output signal.

After mobile phone has been exported bell signal, be sent to first triode NPN base stage, this moment, current collection was very low, second transistor collector is high, output signal, meanwhile, because the positive feedback branch that electric capacity is formed acts on simultaneously, first transistor base has been added positive feedback voltage, no matter whether mobile phone has signal to be input to the base stage of first triode, it is high that second transistor collector is always, and signal output is arranged all the time, arrived certain hour after, feedback branch electric capacity differential is full of, feedback branch lost efficacy, so positive feedback is regularly, was not eternal.

For this circuit also should illustrate following some:

One of, why to add positive feedback branch, 3 meanings are arranged, one can be the cell-phone bell signal transition of interrupted class a kind of continuous signal, has enlarged the application kind of mobile phone greatly, make to mobile phone require unaffected.Promptly whatsoever the mobile phone of model all is suitable for.Its two, guarantee each bell signal, be not subjected to the influence of mobile phone " key " user operation, that is afraid of that operating process is a transient state, can both guarantee to launch the required time.This point is very important, because the inventor is applied to the series products of ensuring public security, and non-one of radio coding integrated circuit, but polylith, this is more much longer than the simple radiating circuit time, feedback branch has been arranged after, that operation I guess of short duration can both guarantee to launch required time at every turn.Its three, strengthen amplification quantity, particularly more meaningful to the mobile phone type a little less than the bell signal, improved the reliability of control wireless remotecontrol radiating circuit.

Two, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and this moment, second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of second pipe is fed back the charging of feedback capacity differential, finishes until differential.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, promptly be second triode when full, the positive pole of feedback capacity links to each other with ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, fully can satisfy the necessary preparation of feedback next time.

Three, feedback capacity little with feedback resistance has formed charge constant altogether, adjustable flexibly, be adapted to dissimilar types.

Four, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is bigger, and choose with electrodeless electric capacity is that the electric leakage system is little, feedback branch is more stable, if but with selecting electrodeless electric capacity capacious, sometimes be difficult for looking for, and price is higher, so proposed to become electrodeless method with electrochemical capacitor, choose the method that the negative pole of having used two electrochemical capacitors is connected together among the figure, adopt this method after, capacitance can conveniently make up, and leakage coefficient can improve a lot of a lot, in this programme because of the positive feedback circuit is arranged, highly significant to the stability of raising circuit.

Five, the reason that positive feedback branch has added diode is when the cell-phone bell signal has been added in the base stage of first pipe, not produce loss of signal branch road.

The timing feedback circuit is equivalent to the mobile phone signal pecker, can guarantee the accuracy of signal, is not subjected to the restriction of mobile phone model.

7, many yards launch scenarios have been adopted in the wireless remote control emission of implementing in technical scheme 1, and important meaning is arranged, and main benefit is to be difficult for producing malfunction.Structure of the present invention is that the warning starting switch is the lockhole protection switch, and when cracking lockhole, switch contact is subjected to displacement, and sends the command of execution of having reported to the police, and Telephone set just begins telephone call within doors.Because producing telephone call is a very serious thing, if wrong report, unnecessary terrified with causing, consequence is very serious.And use the apparatus of remote control many now, as locking that automotive door is protected, with release or the like, all want straighforward operation, just formed possible interference source.And adopt the artificial disturbance that just can thoroughly stop this class after many yards.After otherwise many yards radiating circuits have been arranged, must be non-normal door, so have improved the confidence level that the present invention reports to the police greatly if alarm call is arranged.This circuit realizes that its principle of many yards emissions is; When first end output of programme control circut was high-order, it was low that the inverter output that is connected makes the chip select of this coding integrated circuit that is connected, thus this chip select work, and remaining sheet is not worked.Be output as when high when second, in like manner have only corresponding section's chip select work.The 3rd, the 4th reason is the same.Since each the coding integrated circuit with or the door mode be input to modulating tube, so form the form of many yards emissions.

8, increase a coil antenna in the emission, carried out the science lotus root with magnetic sheet electric capacity and close, strengthened the effect of emission.

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

(1), circuit totally constitutes and main feature: adopted traditional classical three end integrated circuits to make the last output of voltage stabilizing.Before the input of three end integrated circuits, increased the one-level emitter follower and made buffer, but the design one different with tradition is not contain consumable accessory zener diode, good reliability during this grade operate as normal.The 2nd, thunderbolt (overvoltage) there are three grades of strick precautions, overvoltage is taken precautions against effective.The 3rd, adopted 3 measures to make adjustable, the easy accent of three end integrated circuit voltage stabilizing values.

(2), the explanation of three-level protective principle has been carried out in lightning protection.One of be between rectification and three end integrated circuits, to have increased emitter follower newly, high back-pressure high power valve is adopted in this pipe design, its back-pressure can reach hundreds of volts, almost is about 10 times of circuit of three-terminal voltage-stabilizing integrated input voltage of 78 series, is equivalent to ability to bear and has improved 10 times.Two be to have increased anti-thunder tube to make second class protection, the voltage limit in the time of can be with thunderbolt is in the scope of tens of volts of puncture voltage.Three be to have increased " lightning protection overvoltage backup " circuit in the base stage that output voltage is adjusted pipe, (voltage-stabiliser tube 127 branch roads), the operating state of this pipe is, be in the no current conducting state at ordinary times, its reason is that selected voltage-stabiliser tube voltage stabilizing value has surpassed the pressure drop of two resistance series arms (128 and 129 series arm) over the ground of emitter follower base stage in the circuit, so by clamper.Formed the benefit of two aspects like this, the one, no current during because of usual work does not produce electrical wear, so can not damage, has guaranteed reliable when using.The 2nd, when input had high pressure, as thunderbolt, or the civil power accident was when having high pressure; 128 and 129 series arm pressure drops raise, " lightning protection overvoltage backup " branch road at this moment, (voltage-stabiliser tube 127 branch roads); automatically conducting immediately produces the pressure limiting function immediately to newly-increased emitter follower base stage, implements protection.Owing to formed three-level protective to thunderbolt, so when bad weather, needn't be to the disconnected power down source of the present invention, and can operate as normal.

(3), can not damage circuit description in civil power higher place and period.Its reason such as back and forward, thunderbolt are a kind of reasons of overvoltage.The lightning protection circuit effect is adapted to civil power unexpected the time too.

(4), can be in the explanation of lower place of civil power and period work.Newly-increased emitter follower is a high inverse-voltage tube, so the secondary low-voltage output end voltage of transformer can design higherly, when civil power is low, rectification output is had compensation like this.So expanded the civil power lower range.

(5), can expand the explanation of civil power excursion.Its reason is that civil power does not damage circuit when high, and when low compensation is arranged, so expanded the operation interval that civil power changes.

(6), take three-terminal voltage-stabilizing value Several Measures adjustable and that easily transfer.One of, design has three ends adjustment voltage stabilizing to be worth adjustable peripheral circuit, in this electricity routing diagram: 133,134,135 3 elements are formed.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve and easily produce in batches and the contradiction of adjusting voltage flexibly.Because three end integrated circuit models and individual difference, the electric current that earth terminal flows out is variant, if only is connected with resistance between its earth terminal and the ground connection, then the resistance of similar resistance is not easy to produce the consistency of pressure drop, difficult batch process.Then can address this problem with diode, only the electric current of pipe inflow diode has the difference of size, and its pressure drop is 0,7 volt, need not adjust so produce in batches.If but this branch road is only used diode, but can not adjust required voltage stabilizing fractional value flexibly, so the present invention has adopted the adjustment branch road of both series connection, in this branch road, diode is coarse adjustment, because of being the major part of pressure drop; And the pressure drop of institute's crosstalk resistance is a minute portions, is accurate adjustment.Three, in adjustable peripheral element, increase by one road branch road (133), to strengthen easy batch process from the output of three ends.Because the electric current of this branch road occupies larger specific gravity in diode and resistance series arm, beneficial to overcoming three end integrated circuit models and individual difference, help producing in batches.The rule of adjusting the three-terminal voltage-stabilizing value is, resistance 134 among the figure, and resistance is high more, and output voltage is high more, otherwise low more.

(7), among the present invention, in the peripheral element of newly-increased emitter follower, the meaning of the voltage stabilizing didoe in the cancellation main thoroughfare and form principle.In traditional design, with the co-design of triode and three end integrated circuits, all need the base stage of emitter follower over the ground branch road add voltage stabilizing didoe, and this voltage-stabiliser tube is the main branch road of switching on for a long time.Its objective is and only in this way could guarantee that this pipe output can be controlled within the rated range.Electronics personnel with batch process know that voltage stabilizing didoe is a kind of easy failed part, particularly are used in the power supply place (voltage-stabiliser tube 127 is to be in long-term "on" position) of long-term energising.For avoiding this problem, the present invention has adopted to be difficult for failed part resistance unit replacement easy-to-damage element voltage stabilizing didoe, the principle that forms is, newly-increased emitter follower base is pressed and is adjusted circuit, (the groundwork path when promptly being operate as normal) is 128 and 129 series arm, rather than " lightning protection overvoltage backup " branch road, that is to say 27 voltage-stabiliser tube branch road.Because this branch road voltage stabilizing value is higher than 128 and 129 series arm pressure drop, by clamper, no current has only accidental cause to wait the overvoltage reason as thunderbolt during operate as normal, and voltage-stabiliser tube 127 just has electric current to pass through among the figure.What also should illustrate simultaneously one is, in the design of series arm 128 and 129, the pressure drop of resistance 129 is main, be essentially three end output voltages as can be seen from Figure 1, (only differing from a PN joint), and when design, the pressure drop of adjusting on the resistance 128 has only the three ten-day period of hot season, just can guarantee that the emitter follower output voltage satisfies the input voltage of three end integrated circuits, because this circuit output essence surely is three end integrated circuits, so its voltage regulation performance can not be affected.The 2nd, provide because the pressure drop on the resistance 129 mainly is a output current by three end integrated circuits, rather than by on the emitter follower base stage partially resistance 126 provide, so track stability and easy tonality are played great role.

(8), improve the Several Measures of reliability: one of, in lightning protection circuit, formed three-level protective, (seeing second).Two, the buffer base press to adjust circuit and is made up of resistance series arm (128 and 129 series arm); do not contain easy failed part voltage stabilizing didoe, not fragile, three; in the protection of the lightning protection third level, design " special substitutes " protected mode branch road, further improved reliability.

Also have following outstanding advantage after the invention process:

1, after mobile phone is received signal, the timing feedback circuit has been arranged, be not subjected to the restriction of mobile phone model, guarantee that each signal is all reliable, use the accuracy of many yards radiating circuits of diode OR gate formula, no matter be that extraneous acoustic jamming or electrical interference all can not produce the malfunction signal, 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 make the receiving unit of signal receiving device, also can be used as mobile phone and independently uses, mobile phone utilance height.Simultaneously, to using machine, can not cause the damage of mobile phone without secondary operations.

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

4, practical, it is of a great variety only to manage mobile phone model, but all is suitable for, and the one, the measure among the present invention can be taken out the call signal of disposable type mobile phone, and the 2nd, external electric supply socket can both cooperate with a lot of mobile phones after adopting the UBS socket.

5, strong security, easy to maintenance, because the conversion arbitrarily of the card number of mobile phone is operated also very simple.

6, performance is good, embodies in the following areas: the one, lightning protection effect is good, has the lightning protection three-level protective, and is not fragile at thunderstorm season, supporting electrical equipment needn't quit work at thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply wideer adaptive capacity is arranged, promptly be to make the protector of being joined work and be unlikely to damage when the high place of voltage 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.And the existing achievement of inventor is security personnel's classes, need be to the floating charge circuit of storage battery, and this circuit can not be an integer value.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.
