In the automated production of current door industry, there is no satisfactory receiver.Consult existing pickoff part, also do not have a kind of sensor can directly meet above-mentioned 3 requirements and do sensing adapter.

Realize that this technical scheme requires to mainly contain following difficult point:

1, the kind of moment sensor is a lot, can convert a kind of physical quantity to electronic circuit required initiating signal.But, in numerous kinds, but the neither one kind has directly the network received is notified from a phone call to signal at a distance, change the required function that plays dynamic control signal of electronic circuit into.

2, cell phone can receive remote call signal easily from communication network, but it need to change the maintenance of battery, and this is one.It two is if adopt the scheme power supply of current extensive exchanges stabilized voltage supply design, also has following difficult point, the one, and the lightning protection grade is not high, and such joined equipment will may damage in thunderstorm season, or cisco unity malfunction, will cause serious situation out of control.The 2nd, can not in the scope very wide at civil power, work, directly affected institute's match appliance range of application.The 3rd, voltage stabilizing numerical value can not be transferred to the voltage stabilizing value of decimal neatly, as 3.7 volts, and 12.7 volts, so can not adapt to the requirement of match appliance.Why above deficiency is arranged, its main cause be subject to the integrated circuit of the voltage stabilizing of 78 series intrinsic parameter restriction and cause.If, so good service can not be realized for mobile phone in institute's distribution source, so can not realize through engineering approaches with mobile phone as the remote control reception control device, more can not become a kind of product of excellence.

3, the type kind of mobile phone is many, also is being subject to the impact of board simultaneously, and the ring mode has difference more, if any interrupted mode, continuous mode is arranged, and the forte class is arranged, and the off beat class is also arranged, etc.These ring modes variant all becomes the discreteness of taking out signal, so how ringdown a kind of " original " signal at last could become real control signal reliably to these " original signal ".

Summary of the invention

The objective of the invention is to design a kind of applicable receiver, be mainly used in the automated production of supporting door industry, make it to become a kind of receiving-member of realizing that phone opens the door.Its purpose one is the patent that the deviser is applied for, does further to supplement.Two are to provide a kind of sensor kind of excellence, and the outstanding product of exploitation door industry class provides larger space.

Concrete measure of the present invention is:

1, a kind of easy to operate receiver is by network telephone, additional cellular phone power supplies, and connecting circuit, installation capsule, the large common composition of installing forms jointly;

Wherein network telephone is: on loudspeaker two pile crowns with an end interconnection network telephone set of one group of wire, the other end is as the export-oriented output of signal; Connect the power supply source two ends in network telephone with an end of another group wire, the other end is connected on mobile phone and safeguards in power supply output.

The base stage that output voltage is adjusted pipe has connected two groundings, and article one branch road is the positive pole that base stage has connected first stabilivolt, the negative pole of this stabilivolt resistance eutral grounding of having connected; The second branch road is that base stage has connected another two stabilivolt positive poles, the minus earth of this stabilivolt.

Terminated at the emitter of output voltage adjustment pipe with a resistance one, the other end is as the positive pole output of mu balanced circuit; With two diode series connection, connect one of diode cathode and terminated at the base stage of adjusting pipe, the other end has been connected on the positive pole output of mu balanced circuit.

Terminate at the output of voltage stabilizer with one of a resistance, the other end is connected on output voltage and adjusts stabilivolt point in series with a resistor in base stage article one branch road of pipe.

With the output of the positive pole of mu balanced circuit, jointly formed mobile phone with the extension line of ground wire and safeguarded power supply output.

Wherein connecting circuit is: be connected on the base stage of first triode after the resistance of lead-in wire series connection with loudspeaker two pile crowns that are connected to the signal mobile phone, the grounded emitter line of this triode, collector has connect two-way, one of be with power supply, to join after having connect a resistance; Two be connect a resistance an end, another termination of this resistance the base stage of second triode.

Second transistor collector connect two-way, one of be to have connected after a resistance to be connected on power supply; Two are ends that connect a feedback capacity, the other end of this feedback capacity has been connected after a diode and resistance and has been connected on the base stage of first triode, also connects a resistance between this end of this feedback capacity and ground.

Second transistor collector outwards exported and drawn signal wire.

2, the triode in additional cellular phone power supplies is high back-pressure large power triode, and diode used is the face bonded type diode.

3, the line between each parts all adopts heat-shrink tube to tighten.

4, the feedback capacity in connecting circuit is two electrochemical capacitor series connection, and wherein the negative pole of two electric capacity links together.

5, the installation capsule should be fixed on installation large in,, the capsule surrounding is drilled with aperture, the line between each parts all adopts heat-shrink tube to tighten.

6, network telephone is the radio communication mobile phone.

The relevance of above measure further is explained as follows:

The principle of the functional device one, opened the door as a kind of phone is that what at first to need is to receive the function that outside room, phone is called out, and outside it receives room, after the calling of phone, just can send the instruction of opening the door.In the present invention, mobile phone Main Function used is to be used as to receive mobile phone (" key " mobile phone) calling outside room.While calling out due to mobile phone outside room, receiver ring of the present invention rings within doors, and signal is drawn by loudspeaker, so receive signal, is reliable.

If two only use the signal mobile phone as receiving network signal, but do not have excellent mobile phone to safeguard power supply, can't become the product that can receive on a kind of engineering, more can not become the product that a kind of excellent performance is good, because mobile phone needs normal battery to safeguard, if the employing Alternating Current Power Supply, also essential will in the situation that multiple severe can normal operation, so the power supply of safeguarding of mobile phone becomes a key component of the present invention.

Because mobile phone is safeguarded power supply and is played an important role in the present invention, be directly connected to all round properties of main body of the present invention, have great significance, for this reason the inventor to have designed in the present invention a kind of mu balanced circuit supporting with it, the characteristics of this circuit are, in lightning protection, and more traditional design in the requirement to civil power, all being greatly improved, this is one, it two is that this circuit has only been used one active, this not only is conducive to the reliability of circuit, and (in circuit, triode is easy failed part, in the situation that meet performance, fewer, obviously reliability is higher.) and be easy to batch production.Now this circuit is described in detail as follows:

One, the cardinal principle of voltage stabilizing:

1, output voltage is adjusted pipe and has been connected into emitter follower and amplifies form, has very strong negative feedback, once, after base stage reference circuit line parameter circuit value determines, adjust pipe and just can be stabilized on a concrete numerical value, its precision can meet the requirement of a lot of electronic products.

2, compare many index excellence and reason with 78 serial integrated regulators:

(1), greatly improved the lightning protection grade.Its reason is that three-level protective has been carried out in lightning protection, and one of measure is to adjust pipe to have adopted high back-pressure high power valve, and its back-pressure can reach hundreds of volts, is almost 10 times of left and right of the 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; can be by the limiting voltage in when thunderbolt in the scope of tens of volts of voltage breakdown; three be that the base stage of adjusting pipe at output voltage has increased the Liang Tiaozhi road; these two branch roads have formed complex function; formed again duplicate protection, the concrete condition back also will describe in detail.And wherein one of function is to have formed the protection of the lightning protection third level.Main cause be it by the base stage clamper to of an emitter follower fixing value, while shoving during thunderbolt, can become the leakage path of thunder-strike current, so that the output of emitter follower can not produce is high-order.

(2), at civil power, higher place and the period can not damaged circuit.Its reason is that the adjustment pipe is high inverse-voltage tube, and the voltage of only managing now bridge-type output is high, but also can be far below the high inverse-voltage tube withstand voltage.

(3) place that can be lower at civil power and period work.It wants reason one is to be high inverse-voltage tube because adjusting pipe, so can design the bridge-type output voltage higherly when design, when civil power is low, at this moment bridge-type voltage can not be very low, just can do certain compensation.The 2nd, output voltage adjustment pipe, can not produce the additional electrical pressure drop, and it directly is adjusted into the output voltage stabilizing circuit output voltage by the bridge rectifier output voltage, be to need only bridge-type voltage higher than output voltage, and this voltage can make triode work, just energy voltage stabilizing.(illustrate: if the traditional design scheme that adopts traditional triode to connect with three end integrated circuit, because three ends will be stable work, voltage that must input end is higher than definite value of output terminal, and if the input prime of three end integrated circuit string has the triode transmitter, input end 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 circuit.And, when civil power is low, this is valuable voltage.）

(4), can expand the civil power variation range.Its reason is due to upper two reasons, does not damage circuit when civil power is high, and still can work when low.So can expand widely the working range that civil power changes.

3, can adjust the reason of different output voltage stabilizing values.Adjust the emitter follower base stage parameter value of the first branch road over the ground, with regard to the capable of regulating base voltage, then adjust output voltage.In two branch roads, the voltage stabilizing value of the first branch road is low, and the voltage stabilizing value of the second branch road is high, so when normal operation, the second branch road is by clamper, no current.And the voltage drop that the stabilivolt in the first branch road produces is leading part, can select its voltage stabilizing parameter to carry out coarse adjustment to output voltage, and the voltage that this branch road institute crosstalk resistance produces is little, resistance that can adjusting resistance realizes the accurate adjustment to base voltage, resistance is higher, voltage is higher, otherwise voltage is lower.Thereby can realize the correction to the accurate value of power supply.Here it should be noted that the reason one that this resistance why can voltage stabilizing is that institute's step-down is little, only account for very fraction of base stage total pressure drop, the 2nd, the pressure drop electric current of this resistance is mainly from the output of voltage stabilizer, and the 3rd, it is little that useful composition accounts for the total current ratio.

4, overcurrent protection principle: when output current is excessive; adjust the resistance drop increase that the pipe emitter is connected; while surpassing certain value; diode current flow in the overcurrent protection branch road; flow into output voltage and adjust the base current minimizing of pipe; load overcurrent is super many, and the base current reduced is more, automatically forms and exchanges the homogeneous tube protection.

5, overvoltage protection principle: when input voltage is too high, when the resistance drop on article one 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 ratings.

One of improve the Several Measures of reliability:, in lightning protection circuit, formed three-level protective, (seeing second).Two, designed the duplicate protection of surge pipe base stage two branch roads over the ground in lightning protection third level protection.Main cause one is in electronic circuit, and stabilivolt is a kind of easy failed part.The 2nd, lightning protection is the emphasis of this programme.Higher than the first branch road, just formed a kind of " special substitutes " protected mode due to the second branch road voltage stabilizing value, its principle is: when just working, this second branch current can be because of the first branch road clamper low by voltage stabilizing, and no current passes through.This branch road only has two kinds of situations when electric current is arranged, and the one, the bridge rectifier output voltage is too high, the excessive second branch road voltage stabilizing value that surpasses of the first branch voltage, two is that in the first branch road, stabilivolt damages open circuit.One of above-mentioned two situations, the second branch road drops into immediately automatically, obviously more reliable than only having a branch road.Three, base stage the second branch road passes through by the clamper no current when normal, do not produce " electrical wear ", not fragile, in a kind of " Status of Backups of forever waiting for ", further strengthened the reliable of circuit.Five, utilize complex function, reduce parts number, but performance do not subtract, as base stage two branch roads over the ground, be reference voltage, be again overvoltage protection, form the passage that shoves during again to thunderbolt.

4, in the present invention, connecting circuit plays an important role to the signal reliability in the present invention, only have and adopted it original ringdown could be become to 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 connecting circuit: one of after the present invention receives ringdown, it not final purpose, final purpose is to remove to promote the wireless remote control radiating circuit with ringdown, make it to send the initiating signal of wireless remote control emission, then make supporting performer move after receiving remote signal, (as the inventor has been fruitful, be antitheft door, to allow the propulsion system that open the door of door start) so, how ringdown reliably promotes radio transmitter circuit, it is an important technology key, its reason is because mobile phone is of a great variety, some rings are on-off states, has plenty of continuous state, some signals are strong, a little less than some signals, if there is no a kind of good connecting circuit, be difficult to guarantee the reliability of product, and adaptability is widely arranged.Two because connecting circuit has been arranged, therefore the mobile phone adapted 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 after signal to adopt radio transmission and execution unit to contact, and any execution unit can add receiving trap and realize mating with the present invention, so execution unit that can be supporting is also widely.

(2), the operating principle of connecting circuit: (see 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 ringdown, be sent to first triode NPN base stage, now current collection is very low, second transistor collector is high, output signal, meanwhile, the positive feedback branch formed due to electric capacity 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, second transistor collector is always high, signal output is arranged all the time, after having arrived certain hour, the feedback branch Capacitance derivative is full of electricity, feedback branch lost efficacy, so positive feedback is regularly, 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, greatly enlarged the application kind of mobile phone, make to mobile phone require unaffected.Whatsoever the mobile phone of model is all applicable.Its two, guarantee each ringdown, be not subject to the impact of mobile phone " key " user operation, that is afraid of that operating process is transient state, can 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, after feedback branch has been arranged, that is operation of short duration I guess, can guarantee to launch required time at every turn.Its three, the strengthening amplification quantity, particularly meaningful to the mobile phone type a little less than ringdown, improved the reliability of controlling the wireless remote control radiating circuit.

Two, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and now the second pipe collector is high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe, to the charging of feedback capacity differential, is fed back, until differential finishes.Second aspect is that the rejuvenation of feedback is reliable, when first transistor base is input as when low, 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, fully can meet the necessary preparation of feedback next time.

Three, feedback capacity micro-with feedback resistance has formed altogether charging rate, adjustable flexibly, be adapted to dissimilar type.

Four, in feedback branch, electric capacity selects electric capacity capacious, the debugging surplus is larger, and choose with electrodeless electric capacity, be that the electric leakage system is little, 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 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 in figure, after adopting this method, capacitance can conveniently combine, and leakage coefficient can improve a lot, in this programme because the positive feedback circuit is arranged, to the stability that improves 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.

Six, because this circuit has positive-feedback circuit, it is that circuit is more stable that its input line has adopted the benefit of shielding line.

5, in the present invention, when network telephone selects the base type, still can, but the installation box will change, with to meet the need, so proposed measure 9, the benefit of this special mounted box is conveniently to answer the call, but can not free call on somebody else's expense through illegal means obtain telephone cipher.

Following outstanding advantages is arranged after the invention process:

1, mobile phone can receive the signal of wireless communication networks reliably, and the operator is not subject to the impact of distance and carries out straighforward operation, realizes that phone opens the door, and is a kind of method very easily.Simultaneously anti-interference strong, 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 trap that a kind of phone opens the door.

2, mobile phone receives signal by the wireless radio transmission network, so, place the constraint (as adopted base, will be subject to the lead-in wire interface constraints of telephone wire) that is not subject to environment, do not affect attractive in appearancely within doors, for its people, do not know, to the secret benefit of all bringing yet.

3, the mobile phone additional supply performance due to supporting is very good, not only can make mobile phone not change the maintenance of battery, and can guarantee that the present invention is in thundery sky work, it is not perishable when civil power is high, the situation low at civil power can work, so not only guaranteed of the present inventionly for the use by receiving the net signal, and can become the receiver of an excellence.

4, because supporting mobile phone additional supply can be adjusted output voltage flexibly, nor be subject to the impact of official seal mode, also be not subject to the impact of board, thus can be unrestricted as the kind of signal mobile phone, so this bright exploitativeness is strong.

5, simple to operate, and the impact that not be accustomed to by the operator, be that the operator makes to call out and can grow, also can be short.

6, strong security, the one, cell phone password is 11, the 2nd, can change at any time, the 3rd, because the installation box is arranged, no matter adopt mobile phone or base, other people can not obtain password by caller identification by the free call on sb. else's expense through illegal means mobile phone.

7, standard, applicable.When phone adopts Mobile phone type, after opening the large lid of installation, if the user only sees mobile phone, can be convenient for changing mobile phone, or change the cipher card of mobile phone, and lose other irrelevant part, and still have this advantage while adopting the base type.
