Description

Oscillating mode remote control warning receiver

Technical field

The invention belongs to electronic technology field.

Background technology

Realizing the remote opening door operation of door with phone, is a kind of upsurge of social popularity.The state of the art of this series products of existing market is the fixed line phone that the user calls out 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 to a kind ofly receive the transducer of distant signal, and this transducer also should not affect the aesthetic feeling of the original decoration of family except function should meet following requirement, meet following requirement:

1, wants to receive remote signal of notifying from a phone call in electric property, can change the signal of notifying from a phone call into open the door the signal of telecommunication 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 directly the remote call signal that receives, to change the device of the signal of telecommunication kind of opening the door into.

2, cell phone and fixedly base can from communication network, receive easily remote call signal, but they are not a kind of transducers because they all can not be directly outside output electrical signals.Want outside output signal, all must again process by traditional method, inconvenient relevant point in is internally drawn signal, but this do and can affect the integrality of complete machine, and especially easily cause the damage of mobile phone.

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

1, adopts the combination of which type of Communication Equipment and which type of senser element, just can make front 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 two parts of the new compound sensor of what carrier combinations, dependable performance, integral body are relatively attractive in appearance, small volume.

3, owing to mobile phone model and in many styles, the jack disunity will take out the signal of calling, is difficult to implement with unified plug wire mode method.

4, mobile phone will be in continuous duty, and mobile phone need to be changed battery, in case a little less than the electricity, work undesired, so mobile phone can not keep the state that can receive at any time, how to overcome.

5, because the starting of reporting to the police is the key element of alarm, whether reliably he be directly involved in starting, or no malfunction arranged.Show after deliberation, address this problem, must make an effort simultaneously aspect machinery and two in the circuit, cooperatively interact, the effect that just can obtain, but to use what kind of mechanical structure, and what kind of circuit of joining be only best processing method, this also is an important topic that is worth research.

6, present senior product often has (maybe must have) wireless link link, and the product radio transmission 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, the one, because existing socially wireless remotecontrol has been widely used in various fields, such as the lock of locking of automobile burglar, all will use remote control, and these all become wide interference source.The 2nd, there is artificial instrument interference and cracks.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to again the series of problems such as cost, therefore which type of encodes to realize thoroughly to stop all interference in the society with, and reaches again low purpose of cost, also becomes problem one.

7, the inventor has had multinomial electronic technology achievement, belongs to security personnel's equipment class, all needs a kind of preferably stabilized voltage power supply supporting with it, if but present circuit of three-terminal voltage-stabilizing integrated without transformation directly application can not reach preferably effect.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 affected 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, such 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 (such 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, although proposed the scheme of triode and three end integrated circuit co-design, but produced again new contradiction, owing to having 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, such as 5 volts, 8 volts, 12 volts, can't the satisfy the demand float charge voltage of fractional value is such as 12,6 volts, etc., also inconvenient when adjusting its voltage stabilizing value, namely be unfavorable for batch production.

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

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

Summary of the invention

The objective of the invention is to design a kind of transducer of compound character newly, 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 larger space.

Concrete measure of the present invention is:

1, the oscillating mode remote control is guarded against receiver by remote-control receiver, timing feedback circuit, vibration damping thing, multi-code transmitter, modular power supply, the common composition.

The vibration damping thing is fixed on remotely monitored sensor receiver outer surface.

Connect supporting power output socket mouth and cell-phone charging socket with mobile phone external charging output data line.

Remote-control receiver, it is local that one of modular power supply is placed in the electronic circuit device that cooperates with it.

The multi-code transmitter circuit is: connect respectively the input of an inverter in the multichannel output with second programme control circut, the output of each inverter, the chip select end that has connected the integrated circuit of a coding, the output of the integrated circuit of polylith coding connects respectively the input of multiterminal or door, the output of multiterminal or door through a resistance after, be connected to the base stage of wireless remotecontrol radiating circuit modulating tube.

Modular power supply, by anti-thunder tube, penetrate with buffer, the buffer base is pressed Circuit tuning, 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 groundings, 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 over the ground contact of second branch road two resistance series connection of base stage.

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 formed source of stable pressure jointly.

2, in the timing feedback circuit be used be high back-pressure large power triode at utmost point pipe.

3, the vibrating sensor in the remote-control receiver is to be welded on the silver-plated weld tabs with wire first, then two root beads is had the silver-plated weld tabs of wire will be bonded in respectively on the two poles of the earth of piezoelectric ceramic piece, two weld tabs of every utmost point weldering.

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, in the multi-code transmitter circuit be input to modulating tube or door be to form with diode, connect the positive pole of a diode with the output of first coding integrated circuit, the negative pole of diode connects together, and behind a resistance, has connected the base stage of modulating triode.

7, used coding integrated circuit is two 2262 in the multi-code transmitter circuit.

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.Used mobile phone Main Function receives the usefulness of mobile phone outside the room (" key " mobile phone) calling exactly among the present invention.It must have two kinds of functions, and the first function is the calling that can receive telephone set outside the room, and the second function is the function that the signal that will call out is converted into output electrical signals again.Before mobile phone was failed innovation, it only had the first function, and does not have the second function.

2, mobile phone itself has receiving function, and call signal is converted into output electrical signals, the principle that the present invention has adopted vibrating sensor to turn.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 only have 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, although the mobile phone kind is numerous, what have has a receiver J-Horner, have without receiver J-Horner, 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 is fixed with piezoelectric ceramic piece being wrapped the 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, owing among the present invention, having adopted external power supply, so the mobile phone that the present invention powers 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, among the present invention, the timing feedback circuit plays an important role to the signal reliability among the present invention, only have 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, supporting performer is moved after receiving remote signal, (being fruitful such as the inventor is antitheft door, 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 some rings are on-off states, has plenty of continuous state, some signals are strong, a little less than some signals, if there is not a kind of good timing feedback circuit, be difficult to guarantee the reliability of product, and widely adaptability is arranged.Two because the timing feedback circuit has been arranged, therefore the mobile phone that adapts to is not limited by the requirement of mobile phone model can, be widely, this is one; It two is that the present invention receives to adopt behind the signal radio transmission and execution unit to contact, 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: (seeing below Fig. 3 and Fig. 4 in the explanation accompanying drawing).

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 forms 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, the feedback branch Capacitance derivative is full of electricity, 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 change the cell-phone bell signal of interrupted class into a kind of continuous signal, has greatly enlarged the application kind of mobile phone, make to mobile phone require unaffected.Namely whatsoever the mobile phone of model is all applicable.Its two, guarantee each bell signal, be not subjected to the impact of mobile phone " key " user operation, that is afraid of that operating process is 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 is operation of short duration I guess, 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, the second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe is fed back the charging of feedback capacity differential, until differential finishes.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, namely be second triode when full, the positive pole of feedback capacity is connected to the ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, satisfies fully the necessary preparation of feedback next time.

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

Four, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is larger, that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but select electrodeless electric capacity capacious, sometimes be difficult for looking for, and price is higher, so proposed in the measure 6 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 the positive feedback circuit is arranged, to the stability of raising circuit highly significant.

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 the first pipe, not produce loss of signal branch road.

6, multi-code transmitter is adopted in emission among the present invention, and important meaning is arranged in the present invention, and main benefit is to be difficult for producing malfunction.Adopt the many yards artificial disturbances that just can thoroughly stop afterwards this class.This circuit realizes that its principle of multi-code transmitter is; When the 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 of connected, this chip select work of institute, and remaining sheet is not worked.When the second end is output as when high, in like manner only has corresponding section's chip select work.The 3rd end, the 4th end reason is the same.Since each coding integrated circuit with or a door mode be input to modulating tube, so form the form of multi-code transmitter.

7, modular power supply is significant in the present invention, and the spy makes the following instructions this circuit:

(1), circuit totally consists of 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 from tradition is not contain consumable accessory zener diode, good reliability during this grade normal operation.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 limiting voltage 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 among the figure), the operating state of this pipe is, be at ordinary times the no current conducting state, its reason is that selected voltage-stabiliser tube voltage stabilizing value has surpassed the over the ground pressure drop of two resistance series arms (128 among the figure and 129 series arms) of emitter follower base stage in the circuit, so by clamper.Formed like this benefit of two aspects, 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; such 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), automatically immediately conducting; newly-increased emitter follower base stage is produced pressure-limiting function immediately, implement protection.Owing to having 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 work.

(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.Therefore 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, be designed with three ends adjustment voltage stabilizing and be worth adjustable peripheral circuit, in this electricity routing diagram: 133,134,135 3 elements form.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve easily batch production and the contradiction of adjusting flexibly voltage.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, the difficult batch production in batches.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, so batch production need not be adjusted.If but this branch road is only used diode, but can not adjust flexibly required voltage stabilizing fractional value, 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 production.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 batch production.The rule of adjusting the three-terminal voltage-stabilizing value is, resistance 134 among the figure, and resistance is higher, and output voltage is higher, otherwise lower.

(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 to 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 that only in this way this pipe output of guarantee can be controlled within the rated range.Electronics staff with batch production all knows, voltage stabilizing didoe is a kind of easy failed part, particularly is used in the power supply local (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 Circuit tuning, when normal operation (namely be groundwork path) 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 only has accidental cause to wait the overvoltage reason such as thunderbolt during normal operation, 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 as can be seen from Figure 1 three end output voltages, (only differing from a PN joint), and when design, pressure drop on the adjusting resistance 128 only has 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 presses Circuit tuning to be comprised 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.

8, 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, with conversion phone number at any time to strengthen confidentiality.

Also have following outstanding advantages after the invention process:

1, mobile phone can receive the signal of wireless communication networks reliably, and anti-interference strong, and this is because no matter be that extraneous acoustic jamming or electrical interference all can not make sound horn, produces the malfunction signal.Extremely be suitable as the receiving system that a kind of phone opens the door, also can be used as other long-distance remote control simultaneously.

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, and the mobile phone utilance is high.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 subject to the lead-in wire interface constraints of telephone wire as adopting base) that is not subjected to environment, do not affect attractive in appearancely within doors, do not know for its people, to the secret benefit of all bringing yet.

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

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

6, mobile phone no longer is subjected to the restriction of model, and the mobile phone of magnitude of vibrations is all applicable.

7, strengthen amplification quantity, make emission more reliable.

8, modular power supply has following advantage: (1), performance are good, embody 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 wider 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 work 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 to 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.

(2), 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.

(3), debug conveniently easily batch production.

9, thoroughly avoided various types of electrical equipment of social upper existence to disturb, made emission more reliable.
