Description

Earphone vibration receiving system

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:

One, 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.

Two, 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 like this 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 first part of new transducer with receiving remote communication device cell phone, with second part of another kind of senser element as the new compound sensor of the present invention, the new compound sensor of the common composition of two parts, it is converted into output signal with remote signal receive remote call signal from communication network after again.But this forms new compound sensor following specific requirement is arranged again:

1, adopt the combination of which type of Communication Equipment and which type of senser element, the preceding part that just can make new compound sensor receive signal realizes the coupling of signal transmission science with the rear section of output signal.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 attractive in appearance relatively, volume is less.

3, since this transducer the number of being exhaled be the password that opens the door, namely can not allow its people know, therefore should stop it is used mobile phone to obtain phone number by caller identification by others, but use for people within doors is convenient again and change cell-phone number in the ciphered cell phone arbitrarily, so produced a new demand again, what kind of device arranged and handle just can reach this requirement.

4, 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 5 adopt external power supplys to replace the mobile phone storage batterys, allow the mobile phone long-term work, because mobile phone model and in many styles, how the jack disunity realizes external power supply replacement battery of mobile phone with unified plug wire mode.

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

7, the present invention is a kind of special application product, because its main effect is to realize that phone opens the door, it should be in a kind of armed state at any time, namely is to be in normal operating state at any time.Otherwise can not open the door directly influence life.Obviously supporting with it with the power supply design of common household electrical appliances is to be difficult to reach such purpose, its reason one is that ordinary electrical home appliance can not worked when thunderbolt is arranged, can avoid damaging, the 2nd, ordinary electrical home appliance work can only be operated within the common standard, when exceeding standard, damages easily civil power, work and cisco unity malfunction when low, the working range surplus is little, has limited the scope of application of the present invention, the 3rd, the present invention is furnished with storage battery, must carry out the science maintenance, otherwise fragile, the 4th, power supply is flimsy parts in the electrical equipment, in case damage the maintenance difficult of asking someone, and consequence is serious, therefore wants what kind of design, could requirement according to the invention.Also become a difficult problem.Because causing this quality factor of first aspect deficiency is the inherency deficiency of three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series), the voltage of input can not be too high, is generally 30 volts.And have the input of three end integrated circuits when being struck by lightning to surpass this value.Cause the reason of second aspect deficiency to be, 220 volts of civil powers are become bridge rectifier voltage output value after the required low pressure of electronic circuit, can only satisfy city's electric standard of most applications, when the high place of civil power and period, its bridge rectifier output just may be above the amount of imports definite value of three end integrated circuits.For addressing this problem, common conventional method is, after bridge rectifier before the three end integrated circuits, increase the one-level emitter follower newly, its objective is, behind the bridge rectifier overtension, allow emitter follower will export pressure limiting, make this not surpass the rated voltage of three end integrated circuits input.Though such scheme has been expanded the higher limit of bridge rectifier output, but has produced new contradiction, because newly-increased emitter follower can produce the supplementary loss voltage drop.When civil power was low, three end integrated circuits might can be worked, but because there is the additional electrical pressure drop in the emitter follower that increases newly, and three end integrated circuit input ends will step-down, is lower than desirable value, just can not voltage stabilizing.Two are complex circuit.Cause the reason of the third aspect to be, because the output valve of circuit of three-terminal voltage-stabilizing integrated is a certain integer value of fixing, as 5 volts, 8 volts, 12 volts, the float charge voltage of the fractional value of can't satisfying the demand, as 3,7 volts, 12,6 volts, etc.More seriously, in the known designs scheme, being difficult to solve float charge voltage needs high and contradiction that discharge is forced down now.Owing to can not effectively solve the problem of above-mentioned three aspects, so damage easily, this easily produces with regard to having caused the 4th aspect problem, in case namely be to damage, maintenance is difficulty again, influences phone and opens the door, directly influence life.The stabilized voltage power supply of joining in addition, also relates to many-sided problems such as cost cost and reliability.

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

Summary of the invention

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, earphone vibrates receiving system by the remotely monitored sensor receiver, the timing feedback circuit, and the installation box, the vibration damping thing, supporting power supply is formed jointly.

The remotely monitored sensor receiver is made of jointly mobile phone, vibrating sensor, and vibrating sensor high impedance earphone is fixed on the mobile phone, draws output line at the lead-in wire pile crown of high impedance earphone as signal with wire bonds.

The lead-in wire pile crown of high impedance earphone is drawn output line as signal; Be connected on the base stage of first triode behind resistance of this line series connection, the grounded emitter line of this triode, collector electrode has connect two-way, one of be to join with power supply after having connect a resistance; Two are ends that connect a resistance, another termination of this resistance the base stage of second triode.

Second transistor collector outwards exported and drawn holding wire, connects the remote control emission then.

The vibration damping thing is fixed on remotely monitored sensor receiver outer surface, again the remotely monitored sensor receiver is installed in the installation box, signal is drawn outside the output line outlet box.

Supporting power supply is by AC voltage-stabilizing circuit, the floating charge circuit, and the accumulator cell charging and discharging switching circuit, the combined balance system circuit is formed jointly: AC voltage-stabilizing circuit is: alternating current has exported 4 the tunnel behind over commutation; The one, and be connected an anti-thunder tube between ground wire; The 2nd, and be connected an electric capacity between the ground; The 3rd, having connected a triode namely is the collector electrode that output voltage is adjusted pipe; The 4th, connected an end of a resistance; The other end of this resistance has connected the base stage of output voltage adjustment pipe.

The base stage that output voltage is adjusted pipe has connected three branch roads; The one, reference voltage branch road, this branch road are the positive poles that base stage has connected a voltage-stabiliser tube, the negative pole of this voltage-stabiliser tube grounding through resistance of having connected; The 2nd, backup protection branch road, this branch road are the positive poles that has connected the another voltage-stabiliser tube in the base stage of output voltage adjustment pipe, the minus earth of this voltage-stabiliser tube; Three is capacitance cathodes, this electric capacity minus earth.

Terminated at the emitter that output voltage is adjusted pipe with resistance one, the other end is as the output point of voltage stabilizing circuit float charge voltage; With two diode series connection, one of diode cathode has terminated at the base stage of adjusting pipe, and the other end is connected on the output point of the emitter float charge voltage of adjusting the stream organ pipe.

Connect with diode with a resistance, diode cathode has terminated at the float charge voltage output point of voltage stabilizing circuit, diode cathode terminates at the contact of connecting of voltage-stabiliser tube and resistance in first branch road, and this contact has also connected the positive pole of an electric capacity, this electric capacity minus earth.

The floating charge circuit is: namely be that one of floating charge isolation resistance has terminated at the float charge voltage output point with a resistance, the other end has been connected on the positive pole of storage battery.

The accumulator cell charging and discharging switching circuit is: having connect a PNP triode at the positive pole of storage battery namely is the emitter that discharges and recharges electronic switch, has terminated at the base stage of this triode, the other end ground connection of resistance with one of a resistance; Positive pole with a diode is connected rectification output, and its negative pole end has been connected the base stage that discharges and recharges electronic switch, and the collector electrode that discharges and recharges electronic switch has been connected on alternating current-direct current mixed voltage circuit output point.

Wherein the output of combined balance system circuit is: the output point of float charge voltage becomes alternating current-direct current mixed voltage circuit output point after connecting through two diodes, and this point also is the final output point of circuit of the present invention.

2, the isolation resistance of floating charge circuit can replace with high back-pressure large power triode in the supporting power supply, circuit is to have terminated at the float charge voltage output point with one of a resistance, the other end has been connected on the base stage of a triode, the collector electrode of this triode is connected on the output after the rectification, and emitter has been connected on the positive pole of storage battery.

3, the rectification circuit in the supporting power supply is connected into first branch road with two diodes, be connected into second branch road with other two diodes, the positive pole of two groups of diodes links together becomes the negative pole of rectifier output, two diode cathodes link together, the positive pole of forming rectification output, the live wire of civil power is through having connected the contact of the diode series connection in first branch road after the series capacitance, the zero line side of civil power has then connected the contact of second bypass diodes series connection.

4, used triode is high back-pressure large power triode in the supporting power supply, as 3DD15.

5, the edge joint mode of vibrating sensor and mobile phone is to paste with the coagulating type white glues to form.

6, in the timing feedback circuit be the form of having formed self-locking with two high back-pressure large power triodes.

7, the electrodeless electric capacity in the timing feedback circuit is to be in series with two electrochemical capacitor negative poles.

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 the function that the signal that will call out is converted into output signal.Before mobile phone was failed innovation, 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 sensor special, 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, the high impedance earphone 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 high impedance earphone 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 high impedance earphone export sensing telecommunications.The high impedance earphone 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 the high impedance earphone is glued on the mobile phone, do not destroy mobile phone integral body fully.The 4th, anti-interference strong, because the high impedance earphone tightly is bonded on the mobile phone, must mobile phone continuous shaking high impedance earphone, just have output.So extraneous general interference is not easy to make it to trigger.After the mobile phone integral body that the high impedance earphone is fixedly arranged being wrapped vibration damping thing such as towel, the interference in the external world can be reduced to minimum.

4, owing among the present invention, used Alternating Current Power Supply part and the common duplicate supply electricity mode of forming of storage battery.So the mobile phone that the present invention powers can long-term work.Do not needed battery of mobile phone.Thereby mobile phone one is not afraid of original mobile phone and needs replacing because electricity is weak at work, and two are not afraid of extraneous AC outage can not work.Mobile phone can long-term work, at any time is in the reception stand-by state.Also only in this way could guarantee the dependable performance of product, therefore also just can be contained in the enclosure, produce following bright spot again.

5, 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, strengthening confidentiality, owing to dailyly do not need to open lid, also can solve the maintenance issues that changes battery with conversion phone number at any time.

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

(1), the meaning of timing feedback circuit: one of after the present invention receives bell signal, it or not final purpose, final purpose is to remove to promote the wireless remotecontrol radiating circuit with bell signal, make it to send the initiating signal of wireless remotecontrol emission, supporting performer is moved after receiving remote signal, (being fruitful as the inventor is antitheft door, be to allow the power set that open the door of door start) so, how bell signal reliably promotes radio transmitter circuit, be an important technology key, its reason is because mobile phone is of a great variety, and the ring that has is on-off state, has plenty of continuous state, the signal that has is strong, a little less than the signal that has, if there is not a kind of good timing feedback circuit, be difficult to guarantee reliability of products, and adaptability is widely arranged.Two because the timing feedback circuit has been arranged, so 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 is formed acts on simultaneously, first transistor base has been added positive feedback voltage, no matter whether mobile phone has signal to be input to the base stage of first triode, it is high that second transistor collector is always, and signal output is arranged all the time, arrived certain hour after, feedback branch electric capacity differential is full of, feedback branch lost efficacy, so positive feedback is regularly, was not eternal.

For this circuit also should illustrate following some:

One of, why to add positive feedback branch, 3 meanings are arranged, one can be the cell-phone bell signal transition of interrupted class a kind of continuous signal, has enlarged the application kind of mobile phone greatly, make to mobile phone require unaffected.Namely whatsoever the mobile phone of model all is suitable for.Its two, guarantee each bell signal, be not subjected to the influence of mobile phone " key " user operation, even 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, second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of second pipe is fed back the charging of feedback capacity differential, finishes until differential.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, namely be second triode when full, the positive pole of feedback capacity links to each other with ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, satisfies the necessary preparation of feedback next time fully.

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

Four, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is bigger, be that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but with selecting electrodeless electric capacity capacious, sometimes be difficult for looking for, and price is higher, so proposed 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 first pipe, not produce loss of signal branch road.

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

The first, measure summation: make the modified model of emitter follower by one of them NPN triode, the float charge voltage of output science; The power supply of work system is provided when civil power is arranged simultaneously, is subjected to city's electric control with a PNP triode, to the automatic switchover of floating charge and discharge, make output not produce 1,4 volt drop.

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

(1), output voltage can be adjusted into the required normal voltage of floating charge arbitrarily.Its principle is, the voltage-stabiliser tube of article one branch road in the base stage (namely be base stage through road that voltage-stabiliser tube is connected with resistance) can be realized the coarse adjustment of output voltage, and resistance can be realized accurate adjustment.It should be noted that, one of reason why resistance can realize accurate adjustment is that the ratio that accounts for of the pressure drop of this resistance is little, two be to have designed output end of pressure-stabilizing to provide electric current by this resistance of Zhi Luxiang of diode and resistance string, and this branch current accounts for leading part in the electric current of this element.Three be to be connected to integrating capacitor between this element and the ground, to avoid the transition of this point voltage; So in this circuit, under the fixed situation of other component parameters, adjust the size of this resistance value, but just pressure regulation, rule is that this resistance value is more high, voltage is more high, otherwise more low.

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

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

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

(5), can the operate as normal reason on the lower ground of civil power.The one, be high inverse-voltage tube because adjusting pipe, can design the bridge-type output voltage higherly, when civil power is low, just can do certain compensation.The 2nd, output voltage adjustment pipe of the present invention can not produce the additional electrical pressure drop, and it directly is adjusted into electric power output voltage with the bridge rectifier output voltage, namely is as long as bridge-type voltage is higher than output voltage, and this voltage can make triode work, just energy voltage stabilizing.(illustrate: if the design that adopts traditional triode to connect with three end integrated circuits, so work that three ends will be stable, voltage that just must input is higher than definite value of output, if and the input prime of three end integrated circuits string has the triode reflector, then input has just increased the auxiliary voltage loss that emitter follower causes, that is to say when civil power is low, after bridge-type output must deduct supplementary loss voltage, be only the input effective voltage of three end integrated circuits.And when civil power was low, this was valuable voltage).

(6), overcurrent protection principle: when output current is excessive, adjust the resistance drop increase that the pipe emitter is connected, the diode current flow in the overcurrent protection branch road, base current minimizing, the automatic adjusting.

(7), overvoltage protection principle: when input voltage is too high; when article one the resistance drop on the branch road increases; the conducting immediately of second branch road, output voltage adjustment pipe base voltage is clamped to the nominal number of the second branch road voltage stabilizing, and output voltage is clamped to rated value.

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

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

This part mainly is made of jointly floating charge resistance, electronic switching tube (PNP pipe), peripheral assembly and balance diode.Because the NPN triode has been exported the floating charge normal voltage, so the floating charge science.Floating charge resistance mainly contains two functions, and the one, to big current limitation, the 2nd, realize that the voltage between AC voltage-stabilizing floating charge output point and the storage battery is isolated, thereby when interchange is arranged, namely can floating charge, can become operation source again.

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

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

Five, alterating and direct current is mixed the explanation of the good voltage principle of output quality:

The effect of balance diode assembly: because AC voltage-stabilizing output is float charge voltage 13,5 volts, passed through two diode step-downs after, reduced to again about 12 volts, because the diode dynamic electric resistor is little, little to load effect, do not produce the output voltage fluctuation, so guaranteed to exchange the correctness of output.And when storage battery power supply, without this part, only through discharging and recharging electronic switch, do not produce pressure drop.

With regard to power supply, this beyond above-mentioned multiple performance, this power supply also has core a bit be active few, thereby bring reliable, cost is low, circuit is simple and easy to produce a series of advantages such as easy debugging.

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 new compound sensor 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, strong security, mobile phone can not be dialed by the stranger after packing in the box, can not produce and steal the cell phone password situation by caller identification, and O﹠M is very convenient.

5, 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, after external electric supply socket adopts the UBS socket, have very strong universal meaning.

6, adopted the dress box of mobile telephone after, its box second box A that can also pack into, the relevant electronic device of packing in the second box A is with circuit board, so whole standard in the installation box.

7, because the present invention has adopted excellent power supply adapted with it, promoted the performance of integral body of the present invention comprehensively, embodied in the following areas: the one, lightning protection effect is good, and not fragile at thunderstorm season, supporting electrical equipment does not quit work because of thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply wideer adaptive capacity is arranged, namely be work and be unlikely to damage when the high place of civil power and period or accidental cause, and also can operate as normal in voltage lower place and period.The 3rd,, can be used for exporting the voltage stabilizing value that there is decimal in generation.Thereby can the required voltage of floating cell.Storage battery is not fragile, and the life-span is long.The 4th,, excellent performance has overvoltage and overcurrent protection.The 5th, particular importance a bit be no matter at floating charge state, or having a power failure the period, all keeping good performance.

8, the advantage of timing feedback circuit: the one, be the cell-phone bell signal transition of interrupted class a kind of continuous signal, enlarge the application kind of mobile phone.The 2nd, guarantee to launch the required time.The 3rd, strengthen amplification quantity, improved the reliability of control wireless remotecontrol radiating circuit.
