The invention mainly supports the use of an existing achievement of an inventor, and is a further improvement for the applied patent of the inventor.
Description
Technical field
The invention belongs to the telecontrol engineering field.
Background technology
Realizing the remote opening door operation of door with phone, is a kind of fashion of social popularity.The state of the art of this series products of existing market is that the user calls out the fixed line phone be placed in family, by voice suggestion, then inputs the password of secondary enabling signal.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, and the expense that phone opens the door is higher, with often voice suggestion being arranged, the information of bringing out crime is arranged.For this reason, the designer had once applied for a patent, and the enforcement of this patent will make up the deficiencies in the prior art.But this patent needs a kind of receiver supporting with it, and this receiver should meet following requirement:
1, want to receive the signal that long distance network is notified from a phone call on electric property, can change the signal of call into open the door the signal of telecommunication simultaneously.For not affecting the aesthetic feeling of the original decoration of family, so also have following requirement.
2, attractive in appearance, independence is strong, becomes independent parts, in order to supporting.
3, be convenient to place flexibly.
In current automated production, there is no satisfactory receiver in the door industry.Consult existing pickoff part, also do not have a kind of transducer 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 power supply design, also has following difficult point, the one, and the lightning protection grade is not high, and such joined equipment will may damage at 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.
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, the one, the patent that the designer is applied for, do further to supplement.Two are to provide a kind of transducer kind of excellence, and the outstanding product of exploitation door industry class provides larger space.
Concrete measure of the present invention is:
1, the receiver of no signal loss is that mobile phone is safeguarded power supply by the signal mobile phone, the common composition.
Wherein: the signal mobile phone is on loudspeaker two pile crowns with an end interconnection network mobile phone of one group of wire, and the other end is as the export-oriented output of signal; The two ends that connect the charge power supply of mobile phone with an end of another group wire, the other end is connected on mobile phone and safeguards in power supply output.
Mobile phone safeguards that power supply is to have connected a rectification unit with transformer low voltage secondary, between the output of rectification and ground wire, has been connected an anti-thunder tube; Its output has also connected the collector electrode of an output voltage adjustment pipe; Its output has also 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 two groundings, and article one branch road is the positive pole that base stage has connected a voltage-stabiliser tube, the negative pole of this voltage-stabiliser tube grounding through resistance of having connected; The second branch road is the positive pole that the base stage of output voltage adjustment pipe has connected another voltage-stabiliser tube voltage stabilizing value high voltage-stabiliser tube than the first branch road, the minus earth of this voltage-stabiliser tube.
Terminated at the emitter of output voltage adjustment pipe with a resistance one, the other end is as the output of voltage stabilizing circuit; With two diode series connection, connect one of diode cathode and terminated at the base stage of adjusting pipe, the other end is connected on the emitter of adjusting the stream organ pipe.
2, mobile phone safeguards that the triode in power supply is high back-pressure large power triode, as: 3DD15; Diode used is the face bonded type diode.
What 3, rectification circuit was used is full-wave rectification.
4, in rectification circuit, diode used is heavy-duty diode, as: 5408.
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.
Three, because mobile phone safeguards that power supply plays an important role in the present invention, so must introduce below doing safeguarding power supply:
1, the cardinal principle of voltage stabilizing:
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.
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 puncture voltage; 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 rectification 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.Its main cause one is to be high inverse-voltage tube because adjusting pipe, so can design rectifier output voltage higherly when design, when civil power is low, at this moment commutating 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 rectifier output voltage the output voltage stabilizing circuit output voltage, be to need only commutating 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 circuits, because three end integrated circuits will be stable work, voltage that must input is higher than definite value of output, and if the input prime of three end integrated circuits string has the triode reflector, input has just increased the auxiliary voltage loss that emitter follower causes, that is to say when civil power is low, after rectification output must deduct supplementary loss voltage, be only the input effective voltage of three end integrated circuits.And, when civil power is low, this is valuable voltage).
(4), can expand the civil power excursion.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 voltage-stabiliser tube 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.
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 rated value.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 voltage-stabiliser tube 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, voltage-stabiliser tube 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.
6, in power supply, rectification circuit used is full-wave rectification, its circuit is: the rectification circuit in supporting power supply is the positive pole that the two ends of the secondary side of transformer has connected respectively two diodes, the negative pole of two diodes connects together becomes the positive source output after rectification, the centre cap ground connection of pressure-changing secondary lateral coil, become the negative pole output of power supply.
Following outstanding advantages is arranged after the invention process:
One, mobile phone can receive the signal of wireless communication networks reliably, and anti-interference strong, and this is because no matter be that extraneous acoustic jamming or electrical interference all can not make sound horn, produces the malfunction signal.Extremely be suitable as the receiving system that a kind of phone opens the door.
Two, 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.
Three, strong security, the one, cell phone password is 11, the 2nd, can change at any time.
Four, the mobile phone additional supply performance due to supporting is very good, not only can make mobile phone not do the maintenance of changing 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.
Five, because supporting mobile phone additional supply can be adjusted output voltage flexibly, thus can be unrestricted as the kind of signal mobile phone, so this bright exploitativeness is strong.
Six, mobile phone safeguards that power supply only used a pipe, and reliability is high.
