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 present extensive exchanges voltage-stabilized power supply design, also has following difficult point, the one, and the lightning protection grade is not high, and such equipment of joining will may damage in thunderstorm season, or cisco unity malfunction, will cause serious situation out of control.The 2nd, can not in the very wide scope of 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, such as 3.7 volts, 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.So if good service can not be realized for mobile phone in institute distribution source, so namely 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 subjected 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 bell signal a kind of " original " signal at last could become real reliably control signal 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 designer is applied for, does further to replenish.Two 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 convenient-to-running fore-lying device is: by network telephone, and additional cellular phone power supplies, connecting circuit, installation capsule, the large common composition of installing.

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

Wherein additional cellular phone power supplies is: the secondary side with transformer low voltage has connected a bridge rectifier unit, one of output of bridge rectifier be with ground wire between be connected an anti-thunder tube; Two be to have connected the colelctor electrode that an output voltage is adjusted pipe; Three are ends that connected 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 two groundings, and article one branch road is the positive pole that base stage has connected first voltage-stabiliser tube, the negative pole of this first voltage-stabiliser tube resistance eutral grounding of having connected; The second branch road is that base stage has connected another voltage-stabiliser tube positive pole, the minus earth of this voltage-stabiliser tube.

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

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

Wherein connecting circuit is: be connected on the base stage of first triode behind 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, colelctor 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.

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

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

4, the feedback capacity in the 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, be drilled with aperture around the capsule, the line between each parts all adopts heat-shrink tube to tighten.

7, adopt shielding line with the wiring that links to each other of connecting circuit on loudspeaker two pile crowns.

8, one of network telephone is line electricity communication handset, two are radio communication bases, three wired electric bases.

When 9, network telephone adopted the communication base, it installed large and annexation box body is the chain connection mode of an end employing activity, and lid exposes the position of the earphone of base when closed box.

The relevance of above measure further is explained as follows:

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

If two only use the signal mobile phone as receiving network signal, but there is not 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 good product of a kind of excellent performance, because mobile phone needs normal battery to safeguard, if the employing Alternating Current Power Supply also must can work in multiple abominable situation, so the power supply of safeguarding of mobile phone becomes a key component of the present invention.

Three, because power supply is important component part of 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 (triode is easy failed part in circuit, is satisfying in the situation of performance, fewer, obviously reliability is higher.) and be easy to batch production.Now this circuit is described in detail as follows:

1, 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, almost is about 10 times of circuit of three-terminal voltage-stabilizing integrated input voltage of 78 series, is equivalent to ability to bear and has improved 10 times.Two be to have increased anti-thunder tube to make second class protection; can be with the limiting voltage in when thunderbolt in the scope of tens of volts of breakdown voltage; three be to have increased by two road in the base stage that output voltage is adjusted pipe; these two branch roads have namely 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 is in its base stage clamper to fixing value with emitter follower, when shoving during thunderbolt, can become the leakage path of thunder-strike current, so the output of emitter follower can not produce a high position.

(2), can not damage circuit in civil power higher place and period.Its reason is that the adjustment pipe is high inverse-voltage tube, and only the voltage of pipe bridge-type this moment output is high, still also can be far below the high inverse-voltage tube withstand voltage.

(3) can be in civil power lower place and period work.It wants reason one is that so can design the bridge-type output voltage higherly when design, at this moment bridge-type voltage can not be very low when civil power is low, just can do certain compensation because the adjustment pipe is high inverse-voltage tube.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 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 traditional design scheme that adopts traditional triode to connect with three end integrated circuits, because three ends will be stable work, voltage that must input is higher than definite value of output, if and the input prime of three end integrated circuits string has the triode transmitter, 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.）

(4), can expand the civil power excursion.Its reason is owing 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.

Can adjust the reason of different output voltage stabilizing values.Adjust the over the ground parameter value of the first branch road of emitter follower base stage, 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 during normal operation, the second branch road is by clamper, and no current.And the voltage drop that the voltage-stabiliser tube in the first branch road produces is leading part, can select its voltage stabilizing parameter that output voltage is carried out coarse adjustment, and the voltage that this branch road institute crosstalk resistance produces is little, the leading composition of electric current that flows into simultaneously this branch road is that the output by mu balanced circuit flows into through feedback resistance, so further make this resistance drop stable, penetrating the electric current that imports with inclined to one side resistance on the base stage of pipe this moment is few part, thereby can transfer and resistance that the master can adjusting resistance realizes 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.

3, overcurrent protection principle: when output current is excessive; adjust the resistance drop increase that the pipe emitter stage is connected; when 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 that then reduces is more, automatically forms to exchange the homogeneous tube protection.

4, overvoltage protection principle: when input voltage is too high, when the resistance drop on article one branch road increases, the immediately conducting 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.

One of improve the Several Measures of reliability:, in lightning protection circuit, formed three-level protective, (seeing second).Two, in lightning protection third level protection, designed the duplicate protection of surge pipe base stage two branch roads over the ground.Main cause one is in electronic circuit, and voltage-stabiliser tube is a kind of easy failed part.The 2nd, lightning protection is the emphasis of this programme.Because the second branch road voltage stabilizing value is higher than the first branch road, just formed a kind of " special substitutes " protected mode, its principle is: when just working, this second branch current can be because of by the first low branch road clamper of 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 voltage-stabiliser tube damages open circuit in the first branch road.One of above-mentioned two situations, the second branch road drop into immediately automatically, and are 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 ", and is not fragile, is 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, such as base stage two branch roads over the ground, namely be reference voltage, be again overvoltage protection, form the passage that shoves during again to thunderbolt.

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

(1), the meaning of connecting circuit: one of after the present invention receives bell signal, it or not final purpose, final purpose is to remove to promote the wireless remotecontrol radiating circuit with bell signal, make it to send the initiating signal of wireless remotecontrol emission, supporting performer is moved after receiving remote signal, (being fruitful such as the inventor is security door, to allow the power set that open the door of door start) so, how bell signal reliably promotes radio transmitter circuit, be an important technology key, its reason is because mobile phone is of a great variety, and 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 connecting circuit, be difficult to guarantee the reliability of product, and widely compliance is arranged.Two because connecting 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 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 bell signal, be sent to first triode NPN base stage, this moment, current collection was very low, second transistor collector is high, output signal, meanwhile, because the positive feedback branch that electric capacity forms acts on simultaneously, first transistor base has been added positive feedback voltage, no matter whether mobile phone has signal to be input to the base stage of first triode, it is high that second transistor collector is always, and signal output is arranged all the time, arrived certain hour after, the feedback branch Capacitance derivative is full of electricity, feedback branch lost efficacy, so positive feedback is regularly, was not eternal.

For this circuit also should illustrate following some:

One of, why to add positive feedback branch, 3 meanings are arranged, one can be the cell-phone bell signal transition of interrupted class a kind of continuous signal, has greatly enlarged the application kind of mobile phone, make to mobile phone require unaffected.Namely whatsoever the mobile phone of model is all applicable.Its two, guarantee each bell signal, be not subjected to the impact of mobile phone " key " user operation, that is afraid of that operating process is transient state, can both guarantee to launch the required time.This point is very important, because the inventor is applied to the series products of ensuring public security, and non-one of radio coding integrated circuit, but polylith, this is more much longer than the simple radiating circuit time, feedback branch has been arranged after, that is operation of short duration I guess, can both guarantee to launch required time at every turn.Its three, strengthen amplification quantity, particularly more meaningful to the mobile phone type a little less than the bell signal, improved the reliability of control wireless remotecontrol radiating circuit.

Two, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and this moment, the second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe is fed back the charging of feedback capacity differential, until differential finishes.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, namely be second triode when full, the positive pole of feedback capacity is connected to the ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, fully can satisfy the necessary preparation of feedback next time.

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

Four, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is larger, that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but 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 the first pipe, not produce loss of signal branch road.

Following outstanding advantages is arranged after the invention process:

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

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

3, because supporting mobile phone additional supply performance 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 by the usefulness of 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 subjected to the impact of official seal mode, also be not subjected 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, namely be that the operator can grow calling, also can lack.

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, so other people can not obtain password by caller identification display by the free call on sb. else's expense through illegal means mobile phone.

7, standard, applicable.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.
