Description

Remotely monitored sensor

Technical field

The invention belongs to an industry technical field of automation.

Technical background

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 from fixed line phone.Adopt such technical measures, following 3 deficiencies are arranged, the one, the phone level of confidentiality figure place of opening the door is not high enough; The 2nd, phone has the off-hook program, thereby the expense that phone opens the door is higher.The 3rd, voice suggestion is arranged more, outwards passed on and brought out the crime signal.For this reason, the designer had once applied for a patent, and the enforcement of this patent will remedy the deficiency of existing product.But it is supporting with it that this patent need a kind ofly receive the remote control head of distant signal, and this controller should meet following requirement: 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 call simultaneously.For not influencing the aesthetic feeling of the original decoration of family, practical transducer is not only attractive in appearance, and independence is strong, becomes independent parts.Also to be convenient to place flexibly, easily supporting with the control board that cooperates.

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

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 signal of telecommunication kind into directly the remote call signal that receives.

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

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

3, adopt the combination of which type of Communication Equipment and which type of senser element, just can make the back part realization signal transmission science coupling of preceding part with the output signal of reception signal.Signal is lost little relatively, thereby makes the electric property of new compound sensor the most reliable and stable.

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

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

6, 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, when low, work and cisco unity malfunction, the working range surplus is little, limited the scope of application of the present invention, the 3rd,, the present invention is furnished with storage battery, the science of must carrying out is safeguarded, otherwise fragile, the 4th, be flimsy parts in the electrical equipment at power supply, in case damage the maintenance difficult of asking someone, and consequence is serious, therefore want what kind of design, ability requirement according to the invention also becomes a difficult problem.Because causing this quality factor of the deficiency of first aspect 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 the deficiency of second aspect 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 the input of three end integrated circuits 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, now in the known designs scheme, be difficult to solve float charge voltage need high and discharge press will be low contradiction.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, remotely monitored sensor is by the network receiver, vibrating sensor, supporting power supply, the common composition.

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

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, be piezoelectric ceramic piece with one of supporting vibrating sensor of network receiver, two are earphones, three are assemblys of loudspeaker and output transformer.

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

4, be piezoelectric ceramic piece with the supporting vibrating sensor of network receiver, this sheet is furnished with and additional the message box is arranged, and the sound hole of message box is close to the mobile phone face, and aims at the sender of mobile phone.

5, the rectification circuit in the supporting 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.

6, the output of supporting power supply can add pecker, connect concrete circuit and be the output with supporting power supply, connect the collector electrode of a NPN triode, be connected between the collector electrode and base stage of this pipe with a resistance simultaneously, series arm with a voltage-stabiliser tube and resistance is connected between the base stage and ground wire of this pipe, terminate at the emitter-base bandgap grading of this triode with one of a resistance, the other end is connected on this pipe base stage voltage-stabiliser tube and the contact that resistance is connected.

7, the circuit that is connected between the base stage of the added pecker of output of supporting power supply and the ground is, with a voltage-stabiliser tube with connect with a resistance again after many diodes are connected, one of this series arm voltage-stabiliser tube terminates at the base stage of triode, an end ground connection that connects resistance, terminate at the emitter-base bandgap grading of triode with one of a resistance, the other end be connected on this pipe base stage voltage-stabiliser tube, diode, with the resistance series arm in the contact of resistance on.

The relevance of the above measure of the present invention further is explained as follows:

1, the principle as the functional device of a kind of phone start is that what at first to need is the function that can receive the phone calling room outside, after the calling of phone, just can send the instruction of opening the door outside it receives the room.Mainly to act on be exactly the usefulness that receives mobile phone outside the room (" key " mobile phone) calling to used mobile phone among the present invention.Therefore the remote control among the present invention receives head and must have two kinds of functions, and first kind of function is the calling that can receive the phone room outside, second kind of function be will calling acoustical signal be converted into the signal of telecommunication of output again.

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

3, piezoelectric ceramic piece is good microphone device, and when the two poles of the earth at them added audio telecom, this sheet can sounding.Test shows: also can be with its inverting function as a kind of 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 bonded on the mobile phone, do not destroy mobile phone integral body fully.The 4th, anti-dried resistance because piezoelectric ceramic piece is close on the mobile phone, must mobile phone continuous shaking just can touch piezoelectric ceramic piece output.So extraneous 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, it is few to minimum the interference in the external world can be slowed down.And as the acoustic vibration transducer similar performance is arranged also with earphone or with the assembly of loudspeaker and output transformer.

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

5, supporting power supply is an emphasis of the present invention, is directly connected to performance of the present invention and reliability, to this circuit, is explained as follows:

The first, measure summation: make the modified model of emitter follower, the float charge voltage of output science by NPN triode wherein; 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 volts 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 designed output end of pressure-stabilizing and provide electric current by this resistance of Zhi Luxiang of diode and resistance string, and this branch current accounts in the electric current of this element and to lead part.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 second branch road voltage-stabiliser tube conducting immediately, 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 anti-thunder tube is housed.Three have voltage stabilizing backup and 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: two branch roads that connected over the ground by output voltage adjustment pipe but appoint; when input voltage is too high; article one, at first conducting of branch road; output voltage adjustment pipe base voltage is clamped to nominal number; the output voltage of electric current of voltage regulation also is clamped to certain number naturally; when article one branch road damaged open circuit, the second branch road dropped into protection immediately automatically.

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 voltage is low, 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 13.5 volts of float charge voltages, 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.

Six, power supply can increase a pecker, is an emitter follower owing to institute adds pecker, and output resistance is low, is conducive to bringing onto load, and the Adjustable Output Voltage of this circuit can be transferred to arbitrary value simultaneously.Be in series and carry out coarse adjustment to the pecker output voltage with voltage-stabiliser tube and diode, be convenient to produce in batches, and resistance can be realized accurate adjustment.

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 has following outstanding advantage after the invention process

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

2, mobile phone is a complete integral body, can do the reception of signal transducer partly, also can be used as mobile phone and independently uses, mobile phone utilance height.Simultaneously, to using machine 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, the one, the measure among the present invention can be taken out the call signal of disposable type mobile phone, the 2nd, after external electric supply socket adopts the UBS socket, with a lot of mobile phones all over cooperating.

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

6, anti-thunder is effective, and not fragile at thunderstorm season, supporting electrical equipment does not quit work because of thundery sky.

7, 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.

8, excellent performance has overvoltage and overcurrent protection, no matter can both keep good performance when.

9, adapting to widely, than traditional stabilized voltage power supply wideer adaptive capacity is arranged, namely is in the high place of civil power during with period or accidental cause, work and can not be stopped, and also can operate as normal in voltage lower place and period.

Embodiment

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

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

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

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

4, the enforcement of supporting power supply in the complete machine:

The first, supporting power supply welds by Fig. 4; Newly-increased pecker can weld by Fig. 5, also can weld by Fig. 6, and two kinds of figure performances are excellent equally; Rectification circuit is pressed Fig. 7 welding.

The second, the debugging of power supply: (1) adjusts output voltage voltage stabilizing value.Adjusting object mainly is to transfer the reference voltage branch road, namely is to transfer element 908 and 909 in base stage first branch road.At first determine the voltage-stabiliser tube parameter in this branch road, allow its voltage stabilizing value not be higher than output voltage values.But can not be low excessively, should account for the leading part of output voltage as 80%, adjust the resistance 909 that this branch road is connected again, and relevant part resistance 914; Its rule is that the resistance when this resistance 909 is more big, and then Shu Chu voltage is more high, otherwise more low.And after definite resistance 909 was decided, the value of resistance 914 was more big, and voltage is more low, adjusts both relations repeatedly, makes it output voltage and meets the requirements.(2), adjusting the backup protection branch road namely is the voltage stabilizing parameter of base stage second branch road: mainly select second branch road the voltage-stabiliser tube parameter the voltage stabilizing value should greater than the pressure drop of first branch road and.(3), adjust the performance of PNP triode, when the first has output when bridge-type, survey that PNP manages emitter and collector voltage should be opened a way.It two is when the bridge-type no-output, and surveying PNP pipe emitter and collector voltage should be less than 0.1.
