Straight formula family expenses information controlled device

Technical field

The invention belongs to the program control technology field.

Background technology

With the remote opening door operation of phone realization door, be a kind of fashion 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 that is placed in the family, by voice suggestion, inputs the password of secondary enabling signal again.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 remedy 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, wanting to receive the signal that long distance network is notified from a phone call in electric property, can be the signal of telecommunication that opens the door with the signal transition of notifying from a phone call simultaneously.For not influencing 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 the present automated production of door industry, there is not satisfactory receiver.Consult existing pickoff spare, also do not have a kind of transducer can directly meet above-mentioned 3 requirements and make the sensing adapter.

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

1, the kind of moment sensor is a lot, can both 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 that receives is notified from a phone call signal at a distance, changes 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 change the maintenance of battery, and this is one.Two, the inventor has had multinomial electronic technology achievement, all needs a kind of stabilized voltage power supply preferably supporting with it, if but present circuit of three-terminal voltage-stabilizing integrated without transformation directly application can not reach effect preferably.Its main cause one is that the lightning protection grade is not high, and the equipment of ensuring public security like this will may damage at thunderstorm season, or cisco unity malfunction, will cause the protector serious period out of control.The 2nd, can not in the very wide scope of civil power, work, directly influenced the range of application of security personnel's equipment.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.Cause a major reason of above 3 deficiencies to be that the inherency of the three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series) in the electronic product causes, the voltage of 78 serial integrated regulator inputs 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.So caused the deficiency of first aspect.Cause the reason of the deficiency of second aspect to be, also because the input voltage rated value of three ends is not high, so the design of the secondary low-voltage side output voltage of transformer is restricted.In present traditional design, though proposed the scheme of triode and three end integrated circuit co-design, but produced new contradiction again, owing to increased easy failed part voltage stabilizing didoe, this just may produce the negative sense result of two aspects, and the one, reliability is affected, and the 2nd, lightning protection effect is affected, 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, can't the satisfy the demand float charge voltage of fractional value is as 12,6 volts, etc., also inconvenient when adjusting its voltage stabilizing value, namely be unfavorable for producing in batches.

In addition, the stabilized voltage power supply of joining also relates to many-sided constraints such as cost cost and reliability, so required stabilized voltage power supply is simple at first sight, but anatomizes, but many places difficult point, also further innovation abrim.

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 receiving system of compound property character newly, 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 receiving system kind of excellence, for the outstanding product of developing door industry class provides bigger space.

Concrete measure of the present invention is:

1, straight formula family expenses information controlled device is by the network receiver, the vibration damping thing, and modular power supply is formed jointly.

Take out two lines from the loudspeaker of mobile phone self, make output line.

Mobile phone is wrapped the vibration damping thing.

Connect the two ends of the charge power supply of mobile phone with an end of one group of lead, the other end is connected on mobile phone and safeguards in the power supply output.

Modular power supply, by anti-thunder tube, penetrate with buffer, the buffer base is pressed and is adjusted circuit, and " lightning protection overvoltage backup " three end integrated circuits and pressure regulation peripheral element combine, and its concrete circuit is.

The secondary side of transformer low voltage has connected three branch roads after over commutation output, one of be to have connected an anti-thunder tube between over the ground; Two are the collector electrodes that connected triode, three are ends that connected a resistance; The other end of this resistance has connected the base stage of triode; The emitter-base bandgap grading of this triode has connected the input of three end integrated circuits.

Penetrate with the buffer base stage and connected two branch road ground connection, article one branch road is the positive pole that base stage has connected a voltage-stabiliser tube, and the minus earth of this voltage-stabiliser tube, this branch road have formed " lightning protection overvoltage backup " branch road; The second branch road is base terminal through ground connection behind the branch road of two resistance series connection; Be connected on the output of three end integrated circuits with the positive pole of a diode; This pipe negative pole has been connected on the base stage contact of second branch road two resistance series connection over the ground.

Terminated at the output of three end integrated circuits with a resistance one, the other end has been connected on the earth terminal of three end integrated circuits, be composed in series a new branch road with diode and resistance, the earth terminal that has terminated at three end integrated circuits of diode cathode in this branch road, other end ground connection.

Outwards export with hot junction and cold end line that output line and the ground wire of three end integrated circuits have been formed source of stable pressure jointly.

2, the vibration damping thing is the bag shape of being made by the plastic film that steam bubble is arranged.

3, in the modular power supply to penetrate with buffer be the large power triode of usefulness.

4, used rectification circuit is full-wave rectification in the modular power supply, and rectifier diode is heavy-duty diode.

5, " lightning protection overvoltage backup " used voltage-stabiliser tube power of branch road is 1W in the modular power supply.

The relevance of above measure further is explained as follows:

One, the principle of the functional device that opens the door as a kind of phone is, what at first 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.Mainly to act on be the usefulness that do to receive mobile phone (" key " mobile phone) calling outside the room to used mobile phone 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 essential will be under multiple condition of severe can operate as normal, so the power supply of safeguarding of mobile phone becomes a key component of the present invention.

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

(1), circuit totally constitutes and main feature: adopted traditional classical three end integrated circuits to make the last output of voltage stabilizing.Before the input of three end integrated circuits, increased the one-level emitter follower and made buffer, but the design one different with tradition is not contain consumable accessory zener diode, good reliability during this grade operate as normal.The 2nd, thunderbolt (overvoltage) there are three grades of strick precautions, overvoltage is taken precautions against effective.The 3rd, adopted 3 measures to make adjustable, the easy accent of three end integrated circuit voltage stabilizing values.

(2), the explanation of three-level protective principle has been carried out in lightning protection.The one, between rectification and three end integrated circuits, increased emitter follower newly, high back-pressure high power valve is adopted in this pipe design, 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.The 2nd, increase anti-thunder tube and made second class protection, the voltage in when thunderbolt can be limited in the scope of tens of volts of puncture voltage.The 3rd, the base stage of adjusting pipe at output voltage has increased " lightning protection overvoltage backup " circuit, (voltage-stabiliser tube 127 branch roads in the accompanying drawing 1), the operating state of this pipe is, be in the no current conducting state at ordinary times, its reason is that selected voltage-stabiliser tube voltage stabilizing value has surpassed the pressure drop of two resistance series arms (128 and 129 series arms in the accompanying drawing 1) over the ground of emitter follower base stage in the circuit, so by clamper.Formed the benefit of two aspects like this: the one, no current during because of usual work does not produce electrical wear, so can not damage, has guaranteed reliable when using.The 2nd, when input has high pressure; as thunderbolt; or the civil power accident is when having high pressure; in the accompanying drawing 128 and 129 series arm pressure drops raise; at this moment " lightning protection overvoltage backup " branch road, (voltage-stabiliser tube 127 branch roads in the accompanying drawing 1), conducting immediately automatically; newly-increased emitter follower base stage is produced the pressure limiting function immediately, implement protection.Owing to formed the three-level protective to thunderbolt, so when bad weather, needn't be to the disconnected power down source of the present invention, and can operate as normal.

(3), can not damage the circuit explanation in civil power higher place and period.Its reason such as back and forward, thunderbolt are a kind of reasons of overvoltage.The lightning protection circuit effect is adapted to civil power unexpected the time too.

(4), can be in the explanation of the lower place of civil power and period work.Newly-increased emitter follower is high inverse-voltage tube, so the secondary low-voltage output end voltage of transformer can design higherly, when civil power is low, rectification output is had compensation like this.So expanded the civil power lower range.

(5), can expand the explanation of civil power excursion.Its reason is that civil power does not damage circuit when high, and when low compensation is arranged, so expanded the operation interval that civil power changes.

(6), take three-terminal voltage-stabilizing value Several Measures adjustable and that easily transfer.One of, design has three ends to adjust voltage stabilizing to be worth adjustable peripheral circuit, and this circuit is by among Fig. 1: 13,14,15 3 elements are formed.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve and easily produce in batches and the contradiction of adjusting voltage flexibly.Because three end integrated circuit models and individual difference, the electric current that earth terminal flows out is variant, if only is connected with resistance between its earth terminal and the ground connection, then the resistance of similar resistance is not easy to produce the consistency of pressure drop, difficult batch process.Then can address this problem with diode, only the electric current of pipe inflow diode has the difference of size, and its pressure drop is 0,7 volt, need not adjust so produce in batches.If but this branch road is only used diode, but can not adjust required voltage stabilizing fractional value flexibly, so the present invention has adopted the adjustment branch road of both series connection, in this branch road, diode is coarse adjustment, because being the major part of pressure drop; And the pressure drop of institute's crosstalk resistance is minute portions, is accurate adjustment.Three, in adjustable peripheral element, increase by one road branch road (133 Fig. 1) from the output of three ends, to strengthen easy batch process.Because the electric current of this branch road occupies larger specific gravity in diode and resistance series arm, beneficial to overcoming three end integrated circuit models and individual difference, be conducive to produce in batches.The rule of adjusting the three-terminal voltage-stabilizing value is, resistance 134 among Fig. 1, and resistance is more high, and output voltage is more high, otherwise more low.

(7), among the present invention, in the peripheral element of newly-increased emitter follower, the meaning of the voltage stabilizing didoe in the cancellation main thoroughfare and form principle.In traditional design, with triode and three end co-design, all need the base stage of emitter follower over the ground branch road add voltage stabilizing didoe, and this voltage-stabiliser tube is the main branch road of switching on for a long time, as accompanying drawing 2.Its objective is and only in this way could guarantee that the output of this pipe can control within rated range.Electronics personnel with batch process know that voltage stabilizing didoe is a kind of easy failed part, particularly are used in the power supply place (road, voltage-stabiliser tube 127 is to be in long-term "on" position) as can be seen from Figure 2 of long-term energising.For avoiding this problem, the present invention has adopted to be difficult for failed part resistance unit replacement easy-to-damage element voltage stabilizing didoe, the principle that forms is, newly-increased emitter follower base is pressed and is adjusted circuit, (the groundwork path when namely being operate as normal) is 128 and 129 series arm among Fig. 1, rather than " lightning protection overvoltage backup " branch road, namely not 127 voltage-stabiliser tube branch road among Fig. 1 yet.Because this branch road voltage stabilizing value is higher than 128 and 129 series arm pressure drop, by clamper, no current has only accidental cause to wait the overvoltage reason as thunderbolt during operate as normal, and voltage-stabiliser tube 127 just has electric current to pass through among the figure.What also should illustrate simultaneously one is, in the design of the series arm 128 and 129, the pressure drop of resistance 129 is main, be essentially three end output voltages as can be seen from Figure 1, (only differing from a PN joint), and when design, the pressure drop of adjusting on the resistance 128 has only the three ten-day period of hot season, just can guarantee that the emitter follower output voltage satisfies the input voltage of three end integrated circuits, because this circuit output essence surely is three end integrated circuits, so its voltage regulation performance can not be affected.The 2nd, provide because the pressure drop on the resistance 129 mainly is output current by three end integrated circuits, rather than by on the emitter follower base stage partially resistance 126 provide, so track stability and easy tonality are played great role.

(8), improve the Several Measures of reliability: one of, in lightning protection circuit, formed three-level protective, (seeing second).Two, the buffer base press to adjust circuit and is made up of resistance series arm (128 and 129 series arms among the figure); do not contain easy failed part voltage stabilizing didoe, not fragile, three; in the protection of the lightning protection third level, design " special substitutes " protected mode branch road, further improved reliability.

(9), rectification circuit all-wave, its circuit is: the secondary two ends of transformer has connected the positive pole of two diodes respectively, the negative pole of two diodes connects together becomes positive source output after the rectification, and the centre cap ground connection of pressure-changing secondary lateral coil becomes the negative pole output of power supply.

Four, because the enforcement of vibration damping thing; improved anti-jamming capacity greatly; therefore incapability is placed on the present invention within doors or vibrates in the bigger door; do not influence its effect; after doing pouch with textile; the favorable damping effect is not only arranged, and very convenient when implementing, also can protect the mobile phone surface.

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 very reliable signal of telecommunication of loudspeaker output.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 make the receiving unit of signal receiving device, also can be used as mobile phone and independently uses, mobile phone utilance height.

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

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

5, performance is good, embodies in the following areas: the one, and lightning protection effect is good, has the lightning protection three-level protective, and not fragile at thunderstorm season, supporting electrical equipment needn't quit work at thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply wideer adaptive capacity is arranged, namely be to make the protector of joining work and be unlikely to damage when the high place of voltage and period or accidental cause, and also can operate as normal in voltage lower place and period.The 3rd,, can be used for exporting the voltage stabilizing value that there is decimal in generation.And the existing achievement of inventor is security personnel's classes, need be to the floating charge circuit of storage battery, and this circuit can not be integer value.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.

6, reliable.Reason one is that in electronic circuit, voltage stabilizing didoe also is one of easy failed part, and in the present invention, voltage-stabiliser tube has been done special processing, so reliability is higher than traditional co-design.Reason two is, newly-increased emitter follower Guan Weigao back-pressure high power valve among the present invention, and reliability generally all is much higher than common triode.

7, debugging is convenient, easily produces in batches.
