Suitable sensor

Technical field

The invention belongs to household electrical appliance technical 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, 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.

7, 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, and 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 second aspect deficiency 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 that triode and three ends connection integrated circuit closes 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, 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, really 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.

Summary of the invention

The objective of the invention is to design a kind of receiving system of compound property character newly, be mainly used in the automated production of supporting door industry, the one, to the patent that the designer applied for, do further to replenish.Two provide a kind of receiving system kind of excellence, for the outstanding product of developing door industry class provides bigger space.

Concrete measure of the present invention is:

1, suitable sensor is by the network receiver, vibrating sensor, and the vibration damping thing, many yards radiating circuits of diode OR gate formula, modular power supply is formed jointly.

Vibrating sensor is fixed on the mobile phone, draws output line at the lead-in wire pile crown of vibrating sensor as signal with wire bonds; The mobile phone that is fixed with vibrating sensor be placed in should with the place of the electronic circuit that is cooperated.

The mobile phone that is fixed with vibrating sensor is wrapped the vibration damping thing.

Many yards radiating circuits of diode OR gate formula: connect a plurality of inverters respectively with a plurality of outputs of program controller and get input, the chip select end that connects polylith coding integrated circuit with the output of each inverter respectively, the positive pole that connects a diode with the output of polylith coding integrated circuit respectively, the negative pole of each diode links together, after a resistance series connection, be connected the base stage of modulation three utmost points in the transmitter unit.

Modular power supply, by anti-thunder tube, penetrate with buffer, the buffer base is pressed and is adjusted circuit, and " lightning protection overvoltage backup " three end integrated circuits and pressure regulation peripheral element combine, and its concrete circuit is.

The secondary side of transformer low voltage has connected three branch roads after over commutation output, one of be to have connected an anti-thunder tube between over the ground; Two are the collector electrodes that connected triode, three are ends that connected a resistance; The other end of this resistance has connected the base stage of triode; The emitter-base bandgap grading of this triode has connected the input of three end integrated circuits.

Penetrate with the buffer base stage and connected two branch road ground connection, article one branch road is the positive pole that base stage has connected a voltage-stabiliser tube, and the minus earth of this voltage-stabiliser tube, this branch road have formed " lightning protection overvoltage backup " branch road; The second branch road is a base terminal through ground connection behind the branch road of two resistance series connection; Be connected on the output of three end integrated circuits with the positive pole of a diode; This pipe negative pole has been connected on the base stage contact of second branch road two resistance series connection over the ground.

Terminated at the output of three end integrated circuits with a resistance one, the other end has been connected on the earth terminal of three end integrated circuits, be composed in series a new branch road with diode and resistance, the earth terminal that has terminated at three end integrated circuits of diode cathode in this branch road, other end ground connection.

Outwards export with hot junction and cold end line that the output line and the ground wire of three end integrated circuits have been formed source of stable pressure jointly.

2, be piezoelectric ceramic piece with the supporting vibrating sensor of network receiver, potsherd is equipped with the message box.

3, the network receiver is to stick with glue the material method of attachment with the fixing means of vibrating sensor and mobile phone.

4, being connected on the branch road of penetrating with " lightning protection overvoltage backup " on the buffer base stage is the series circuit of a voltage-stabiliser tube and several diodes, and the number of diode series connection is one, or more than one.

5, in the diode and resistance series arm between three end integrated circuit earth terminals and ground wire, the number of diode series connection is one, or more than one.

6, used modulating tube is 8050 in many yards radiating circuits of diode OR gate formula.

7, used coding integrated circuit is three 2262 in many yards radiating circuits of diode OR gate formula.

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 bonded 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 the present invention can not be placed within doors or vibrate 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, 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.

7, 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 the voltage stabilizing value of selected voltage-stabiliser tube in the circuit has surpassed the pressure drop of two resistance series arms (128 and 129 series arm) over the ground of emitter follower base stage, 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 triode and three end co-design, 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 has following outstanding advantage after the invention process

1, mobile phone can receive the communication signal of radio net reliably, when receiving signal, and the vibrating effect that it sends, excitation is for the piezoelectric ceramic piece that additional message box is arranged, and piezoelectric ceramic piece can be exported the very reliable signal of telecommunication.So electric property of the present invention is very good, 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.

7, reliable.Reason one is that in electronic circuit, voltage stabilizing didoe also is one of easy failed part, and in the present invention, voltage-stabiliser tube has been done special processing, so reliability is higher than traditional co-design.Reason two is, newly-increased emitter follower Guan Weigao back-pressure high power valve among the present invention, and reliability generally all is much higher than common triode.

8, debugging is convenient, easily produces in batches.

9, the social various interference that exist of going up have thoroughly been avoided.

Embodiment

Fig. 1 to 7 has described the concrete a kind of mode implemented of the present invention jointly.Concrete enforcement is as follows:

1, is welded on the two poles of the earth of the piezoelectric ceramic piece that contains the message box with two leads.

2, the piezoelectric ceramic piece that will contain the message box with adhesive tape is fixed on the face on the handset shell, forms one " integral body " with mobile phone.Its best position is that the aperture that the message box is opened is aimed on the sender of mobile phone sounding body (as loudspeaker).

3, mobile phone " integral body " is put into the pocket of a textile.

4, the present invention is placed on laying of box and a little should be placed on the place that easily cooperates with supporting control board.If both adopt wired electrical connection, supporting with it control board be placed on that door is gone up or door in, then the piezoelectric ceramic piece that contains the message box is fixed on that mobile phone should be placed on that door is gone up or door in.If corresponding control boards is placed within doors, then it is placed within doors.If both adopt wireless radio transmission to connect, then join domain then can be unrestricted between the two.

5, the enforcement of modular power supply:

The first, press the selected relevant elements of Fig. 5 and Fig. 6.Wherein triode is selected high back-pressure high power valve, as 3DD15; Anti-thunder tube puncture voltage parameter is tens of volts; Three end integrated circuits select 78 series; Resistance 128 and 129 choosing heat radiation wattages are greater than 1/2nd wattages; Diode all selects the diode of face mating type among the figure.

The second, adjust three end integrated circuit output values: newly-increased transistor collector of (1), short circuit and emitter-base bandgap grading, the output voltage of (2), coarse adjustment three end integrated circuits reaches output voltage with 135 the number that increases diode and meets the requirements substantially.With reference to figure 2.(3), the output voltage of accurate adjustment three end integrated circuits: the resistance of resistance 134 and resistance 133 is adjusted in coarse adjustment, makes it to meet the requirements, and adjusts the place that the back that finishes disconnects newly-increased transistor collector and emitter-base bandgap grading short circuit.
