Description

USB external power supply family expenses transducer

Technical field

The invention belongs to electronic technology field.

Background technology

With the remote opening door operation of phone realization door, it is 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 in the voice suggestion of the reception fixed line phone from family.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, thereby the expense that phone opens the door is higher.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 it is supporting with it that this patent need a kind ofly receive the transducer of distant signal, and this transducer also should not influence the aesthetic feeling of the original decoration of family except function should meet following requirement, meet following requirement:

1, wanting to receive remote signal of notifying 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.

2, attractive in appearance, independence is strong, becomes independent parts.

3, be convenient to place flexibly.

In the present automated production of door industry, also there is not a kind of transducer directly to meet above-mentioned 3 requirements.

Realize that this technical scheme mainly contains following difficult point:

1, the kind of pickoff 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 the signal of telecommunication kind of opening the door 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 are not a kind of transducers because they all can not directly outwards export the signal of telecommunication.Want outside output signal, all must process again by traditional method, inconvenient relevant point in is internally drawn signal, but this do and can influence the integrality of complete machine, and cause the damage of mobile phone especially easily.

So, the best effective ways that solve existing issue are, form a kind of with existing device, as forming first among the present invention partly with receiving remote communication device cell phone, with and with another kind of senser element as second among the present invention partly, form new composite receiver, allow it from communication network, receive remote call signal after, again remote signal is converted into output signal again.But this has following specific requirement again to the present invention:

1, adopts the combination of which type of Communication Equipment and which type of senser element, just can make preceding part of the present invention 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 compound sensor the most reliable and stable.

2, adopt the new compound sensor two of what carrier combinations partly, dependable performance, integral body are attractive in appearance relatively, volume is less.

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, so mobile phone can not keep the state that can receive at any time.How to overcome.

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, be again the insert earphone jack, and required for the present invention be that the jack of these two groups of signals all needs simultaneously, the one, need the external charge socket, the 2nd, need the jack of call signal, this contradiction takes place how to be overcome.

5, 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 upward wireless remotecontrol has been widely used in various fields now, as the lock of locking of automobile burglar, all will use remote control, and these all become 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 which type of encodes to realize thoroughly to stop all interference in the society with, and reaches cost low purpose again, also becomes a difficult problem.

6, 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 at 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 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, the one, and reliability is affected, 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, the float charge voltage of the fractional value of can't satisfying the demand, as 12,6 volts, Deng, also inconvenient when adjusting its voltage stabilizing value, namely be unfavorable for producing in batches.

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

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 new combined type trans, be mainly used in the automated production of supporting door industry, the one, to the patent that the designer applies for, do further to replenish.Two provide a kind of transducer kind of excellence, for the outstanding product of developing door industry class provides bigger space.

Concrete measure of the present invention is:

1, USB external power supply family expenses transducer is by remote-control receiver, many yards emissions of diode OR gate formula, vibration damping thing, modular power supply, the common composition.

Remote-control receiver is made of jointly mobile phone, vibrating sensor, and 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 vibration damping thing is fixed on remotely monitored sensor receiver outer surface.

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, connected positive pole at a diode respectively with the output of polylith coding integrated circuit, the negative pole of each diode links together, after a resistance series connection, be connected the base stage of modulation triode in the radiating circuit.

Modular power supply: by full-wave rectification, 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.

After the rectification output, connected three branch roads, 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 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 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 output line and the ground wire of three end integrated circuits have been formed source of stable pressure jointly.

2, used diode is face fit type diode in many yards emissions of diode OR gate formula.

3, in the remote-control receiver fixing means one of vibrating sensor and mobile phone is sticked with glue material vibrating sensor is bonded on the mobile phone, be fixed.

4, earlier lead is welded on the silver-plated weld tabs, again weld tabs is bonded on the two poles of the earth of piezoelectric ceramic piece with adhesive tape.

5, 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.

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

7, the rectification circuit in the power supply is the positive pole that the two ends of the secondary side of transformer has connected two diodes respectively, the negative pole of two diodes connects together becomes positive source output after the rectification, the centre cap ground connection of pressure-changing secondary lateral coil becomes the negative pole output of power supply.

The relevance of above measure further is explained as follows:

1, the principle as the functional device 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.It must have two kinds of functions, and first kind of function is the calling that can receive telephone set outside the room, and second kind of function is that the signal that will call out is converted into the function of exporting the signal of telecommunication again.Before mobile phone was not innovated, it only had first kind of function, and does not have second kind of function.

2, mobile phone itself has receiving function, and call signal is converted into the output signal of telecommunication, the principle that the present invention has adopted vibrating sensor to change.Concrete measure is that vibrating sensor is fixed on the mobile phone, after mobile phone has had call signal, will become a kind of vibration source, and at this moment vibrating sensor will be converted into the signal of telecommunication to vibration signal.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 be converted into a kind of can the reception and exportable remote control dedicated receiver, and this is one.It two is can solve to have only a jack on the 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 the restrictions that are not subjected to mobile phone model, all can adopt this method.

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 vibrating sensor.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 vibrating sensor 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 with glue piezoelectric ceramic piece is tightly glued on the mobile phone, do not destroy mobile phone integral body fully.The 4th, anti-interference strong, because piezoelectric ceramic piece tightly is bonded on the mobile phone, must mobile phone continuous shaking piezoelectric ceramic piece, just have output.So extraneous general interference is not easy to make it to trigger.After the mobile phone integral body that piezoelectric ceramic piece is fixedly arranged being wrapped vibration damping thing such as towel, the interference in the external world can be reduced to minimum.And as the acoustic vibration transducer similar performance is arranged also with earphone or with the assembly of loudspeaker and output transformer.

4, after the enforcement measure of the present invention, outside mobile phone in the installation box is not exposed to, so the stranger can not use mobile phone of the present invention and beat outward, steal out the number of reception mobile phone by caller identification, and the people can conveniently start and takes out mobile phone behind the screw cap and change cell phone network number within doors, so that the conversion phone number is to strengthen confidentiality at any time, the mobile phone that supporting power supply is powered can long-term work.Do not needed battery of mobile phone.Thereby mobile phone do not relate to the replacing of battery of mobile phone at work, at any time is in the reception stand-by state.

5, implemented the wireless remote control emission in technical scheme 1 and adopted many yards launch scenarios, important meaning is arranged, 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 the automobile door is protected, with release etc., 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 if alarm call is arranged, so have improved the confidence level that the present invention reports to the police greatly.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 connects makes the chip select of this coding integrated circuit that is connected, this chip select work of institute, 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.

6, 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:

(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 in the time of can be with thunderbolt is limited 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 among the figure), 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 among the figure and 129 series arms) 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 has high pressure; as thunderbolt; or the civil power accident is when having high pressure; in the accompanying drawing 128 and 129 series arm pressure drops raise; at this moment " lightning protection overvoltage backup " branch road, (voltage-stabiliser tube 127 branch roads among the figure), conducting immediately automatically; newly-increased emitter follower base stage is produced the pressure limiting function immediately, implement protection.Owing to formed the 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 the circuit explanation 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 the lower place of civil power and period work.Newly-increased emitter follower is 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 being the major part of pressure drop; And the pressure drop of institute's crosstalk resistance is minute portions, is accurate adjustment.Three, in adjustable peripheral element, increase by one road branch road (133 the figure) from the output of three ends, to strengthen easy batch process.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, be conducive to produce in batches.The rule of adjusting the three-terminal voltage-stabilizing value is, resistance 134 among the figure, and resistance is more high, and output voltage is more high, otherwise more low.

(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 the output of this pipe can control within 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 namely being operate as normal) is 128 and 129 series arm among the figure, rather than " lightning protection overvoltage backup " branch road, namely not 127 voltage-stabiliser tube branch road among the figure yet.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 the 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 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 arms among the figure); 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, mobile phone can receive the communication signal of radio net reliably, when receiving signal, the vibrating effect that it sends, the excited vibration transducer is reliable, vibrating sensor can be exported the signal of telecommunication reliably, so the remote-control receiver electric property is very good, very be suitable for the receiving system that opens the door as a kind of phone, also can make other long-distance remote control simultaneously and use.

2, mobile phone is a complete integral body, can make the receiving unit of signal transducer, also can be used as mobile phone and independently uses, mobile phone utilance height.Simultaneously, to using mobile phone without secondary operations, can not cause the damage of mobile phone.

3, mobile phone adopts the wireless radio transmission network to receive signal, 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, practical, it is of a great variety only to manage mobile phone model, but all is suitable for, and this is the call signal that vibrating sensor can take out the disposable type mobile phone, and the 2nd, external electric supply socket is the standard connector after adopting USB socket, has very strong Practical significance.

5, level of confidentiality height, because one be that the password figure place of mobile phone is many, the 2nd, can often change password.

6, thoroughly avoid social interference of various electrical equipment, also avoided artificial electronic jamming.

7, performance is good, embodies in the following areas: the one, and lightning protection effect is good, has the lightning protection three-level protective, and 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, namely be to make the protector of joining 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 integer value.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.

8, 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.

9, debugging is convenient, easily produces in batches.
