Description

The Direct-type network receiver

Technical field

The invention belongs to household electrical appliance technical field.

Background technology

Realizing the remote opening door operation of door with phone, is a kind of upsurge of social popularity.The state of the art of this series products of existing market is the fixed line phone that the user calls out family, takes out the remote signal of opening the door in the voice suggestion of the reception fixed line phone from family.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, thereby the expense that phone opens the door is higher.For this reason, the designer had once applied for a patent, and the enforcement of this patent will make up the deficiency of existing product.But it is supporting with it that this patent need to a kind ofly receive the transducer of distant signal, and this transducer also should not affect the aesthetic feeling of the original decoration of family except function should meet following requirement, meet following requirement:

1, want to receive remote signal of notifying from a phone call on electric property, can change the signal of notifying from a phone call into open the door the signal of telecommunication simultaneously.

2, attractive in appearance, independence is strong, becomes independent parts.

3, be convenient to place flexibly.

In the automated production of present door industry, also do not have a kind of transducer directly to meet above-mentioned 3 requirements.

Realize that this technical scheme mainly contains following difficult point:

One, the kind of pickoff is a lot, all to convert a kind of physical quantity to a kind of good device of ultra-weak electronic signal, but in the middle of numerous kinds, but not having a kind of is directly the remote call signal that receives, to change the device of the signal of telecommunication kind of opening the door into.

Two, cell phone and fixedly base can receive easily remote call signal from communication network, but they are not a kind of transducers because they all can not be directly outside output electrical signals.Want outside output signal, all must again process by traditional method, inconvenient relevant point in is internally drawn signal, but this do like this and can affect the integrality of complete machine, and especially easily cause the damage of mobile phone.So, the best effective ways that solve existing issue are, with the first part that can receive the new transducer of remote communication device cell phone composition, with second part of another kind of senser element as the new compound sensor of the present invention, the new compound sensor of the common composition of two parts, it receives remote call signal from communication network after, then remote signal is converted into output signal.But this forms new compound sensor, following specific requirement is arranged again:

1, adopt the combination of which type of Communication Equipment and which type of senser element, just can make front part that new compound sensor receives signal and the rear part of output signal realize the coupling of signal transmission science.Signal is lost little relatively, thereby makes the electric property of new compound sensor the most reliable and stable.

2, adopt two parts of the new compound sensor of what carrier combinations, dependable performance, integral body are relatively attractive in appearance, small volume.

3, due to this transducer the number of being exhaled be the password that opens the door, namely can not allow its people know, therefore should stop it is obtained phone number with mobile phone by caller identification by others, but use for people within doors is convenient again and change arbitrarily cell-phone number in ciphered cell phone, so produced again a new demand, what kind of device arranged and process just can reach this requirement.

4, mobile phone will be in continuous duty, and mobile phone need to be changed battery, in case a little less than electricity, work undesired, so mobile phone can not keep the state that can receive at any time.How to overcome.

If 5 with external power supply replacement mobile phone accumulation pond, due to mobile phone model and in many styles, the jack disunity is difficult to implement with unified plug wire mode method.

6, the inventor has had multinomial electronic technology achievement, belongs to security personnel's equipment class, 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 in thunderstorm season, or cisco unity malfunction, will cause the protector serious period out of control.The 2nd, can not work in the very wide scope of civil power, directly affected 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 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 second aspect deficiency 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, although proposed the scheme of triode and three end co-design, but produced again new contradiction, owing to having increased easy failed part voltage stabilizing didoe, this just may produce the negative sense result of two aspects, the one, reliability is affected, the 2nd, lightning protection effect is affected, cause the reason of third aspect deficiency 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, the float charge voltage of 12 volts of fractional values of can't satisfying the demand, as 12, 6 volts etc., also inconvenient when adjusting its voltage stabilizing value, namely be unfavorable for batch production.

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

Due to the existence of above-mentioned difficult point, so there is no now such product.

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 are to provide a kind of transducer kind of excellence, for the outstanding product of developing door industry class provides larger space.

Concrete measure of the present invention is:

1, the Direct-type network receiver is by the remotely monitored sensing receiver, installation box, vibration damping thing, modular power supply, the common composition.

The remotely monitored sensing receiver is made of jointly mobile phone, vibrating sensor, and vibrating sensor is fixed on mobile phone, draws output line at the lead-in wire pile crown of vibrating sensor as signal with wire bonds.

The vibration damping thing is fixed on remotely monitored sensing receiver outer surface, then the remotely monitored sensor receiver is arranged in the installation box, signal is drawn outside the output line outlet box.

Modular power supply: by the output of transformer, bridge rectifier, anti-thunder tube, penetrate with buffer, the buffer base is pressed Circuit tuning, 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, and the one, connected an anti-thunder tube between over the ground; The 2nd, connected the collector electrode of triode, the 3rd, connected an end of 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 groundings, 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 after 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 minus earth.

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

2, being connected on the branch road of penetrating with the backup of the lightning protection overvoltage on the buffer base stage is the series circuit of a voltage-stabiliser tube and several diodes, and the number of diode series connection is one, or more than one.

3, in the diode and resistance series arm between three end integrated circuit earth terminals and ground wire, the number of diode series connection is one, or more than one.

4, penetrating with buffer is high back-pressure high power valve, and the diode that adopts is the rectifier diode of face mating type.

5, the vibrating sensor in the remotely monitored sensing receiver is the assembly that loudspeaker and output become device.

6, be fixedly to be connected with screw with vibrating sensor and mobile phone in the remotely monitored sensing receiver.

The relevance of above measure further is explained as follows:

1, the principle as the functional device 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.In the present invention, mobile phone Main Function used receives the use of mobile phone outside the room (" key " mobile phone) calling exactly.It must have two kinds of functions, and the first function is the calling that can receive phone outside the room, and the second function is the function that the signal that will call out is converted into output signal.Before mobile phone was not innovated, it only had the first function, and there is no the second function.

2, mobile phone itself has receiving function, and call signal is converted into output electrical signals, the principle that the present invention has adopted vibrating sensor to turn.Concrete measure is that vibrating sensor is fixed on 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 vibration signal.This signal of telecommunication can be introduced in control circuit.Therefore mobile phone is through after such processing, and its science is that common mobile phone can be converted into a kind of can the reception and exportable remote control sensor special, and this is one.It two is can solve to only have a jack on 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 the restrictions that are not subjected to mobile phone model, all can adopt this method.

3, the assembly of loudspeaker and output change device is also a kind of good microphone device, and when the two poles of the earth at them added audio telecom, this assembly can sounding.Test shows: also can be with its inverting function as a kind of vibrating sensor.That is to say that when adding vibration signal at their the two poles of the earth, transformer secondary output can be exported the faint signal of telecommunication.If it is fixed on 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 transformer export sensing telecommunications.The area of loudspeaker 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 electrical, reliable.The 2nd, although the mobile phone kind is numerous, what have has a receiver J-Horner, have without receiver J-Horner, though have receiver J-Horner arranged, receiver J-Horner type shape is difficult to unified, and after adopting measure of the present invention, can take out the signal that mobile phone is received with same procedure.The 3rd, easy to operate, as long as first support is dug out loudspeaker slightly little holes, loudspeaker are screwed in the place in support hole, then support is tightly enclosed the machine of stopping get final product, do not destroy mobile phone integral body fully.The 4th, anti-interference strong, because loudspeaker are close on mobile phone, must mobile phone continuous shaking, loudspeaker just have output.So extraneous general interference is not easy to make it to trigger.After the mobile phone integral body that is fixed with loudspeaker is wrapped the vibration damping thing, the interference in the external world can be reduced to minimum.

4, due in the present invention, Alternating Current Power Supply part and the common duplicate supply electricity mode that forms of storage battery have been used.So the mobile phone that the present invention powers can long-term work.Do not needed battery of mobile phone.Thereby mobile phone one is not afraid of and needs a little less than original mobile phone electricity to change at work, and two are not afraid of extraneous AC outage can not work.Mobile phone can long-term work, at any time is in the reception stand-by state.Also the dependable performance of guarantee product only in this way, therefore also just can be contained in an enclosure, produces again following bright spot.

5, after enforcement measure of the present invention, outside mobile phone in the installation box is not exposed to, so the stranger can not use mobile phone of the present invention and beat outward, steal out the number of reception mobile phone by caller identification, and the people can conveniently start and takes out mobile phone after screw cap and change cell phone network number within doors, strengthening confidentiality, do not need open lid due to daily with conversion phone number at any time, can solve the maintenance issues that changes battery yet.

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

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

(2), the explanation of three-level protective principle has been carried out in lightning protection.One of be to have increased emitter follower newly between rectification and three end integrated circuits, high back-pressure high power valve is adopted in this pipe design, 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, the limiting voltage in the time of can be with thunderbolt is in the scope of tens of volts of puncture voltage.Three be to have increased " lightning protection overvoltage backup " circuit in the base stage that output voltage is adjusted pipe, (voltage-stabiliser tube 127 branch roads in figure), the operating state of this pipe is, be at ordinary times the no current conducting state, its reason is that in circuit, selected voltage-stabiliser tube voltage stabilizing value has surpassed the pressure drop of two resistance series arms (128 in figure and 129 series arms) over the ground of emitter follower base stage, so by clamper.Formed like this benefit of two aspects, 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 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 figure), conducting immediately automatically; newly-increased emitter follower base stage is produced pressure-limiting function immediately, implement protection.Due to the three-level protective that has formed thunderbolt, so when bad weather, needn't be to the disconnected power down of the present invention source, and can work.

(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.Therefore 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 the adjustable and easy Several Measures of transferring of three-terminal voltage-stabilizing value.One of, be designed with three ends and adjust the adjustable peripheral circuit of voltage stabilizing value, in this electricity routing diagram: 133,134,135 3 elements form.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve easily batch production and adjust flexibly the contradiction of voltage.Due to 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 ground connection, the resistance of similar resistance is not easy to produce the consistency of pressure drop, is difficult for producing in batches.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 volts, so batch production need not be adjusted.If but this branch road is only used diode, but can not adjust flexibly required voltage stabilizing fractional value, 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, increase in adjustable peripheral element one the road from three ends outputs branch road (133 figure), to strengthen easy batch production.Due to the electric current of this branch road, occupy larger specific gravity in diode and resistance series arm, beneficial to overcoming three end integrated circuit models and individual difference, be conducive to batch production.The rule of adjusting the three-terminal voltage-stabilizing value is, in figure, resistance 134, and resistance is higher, and output voltage is higher, otherwise lower.

(7), in the present invention, in the peripheral element of newly-increased emitter follower, cancel the meaning of the voltage stabilizing didoe in the main thoroughfare and form principle.In traditional design, with triode and three end co-design, all need to 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.Within its objective is that only in this way this pipe output of guarantee can be controlled at rated range.Electronics staff with batch production all knows, voltage stabilizing didoe is a kind of easy failed part, particularly is used in the power supply local (voltage-stabiliser tube 127 is to be in long-term "on" position) 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 Circuit tuning, when normal operation (be namely groundwork path) is 128 and 129 series arm in figure, rather than " lightning protection overvoltage backup " branch road, not namely 127 voltage-stabiliser tube branch road in figure yet.Because this branch road voltage stabilizing value is higher than 128 and 129 series arm pressure drop, during normal operation, by clamper, no current only has accidental cause to wait the overvoltage reason as thunderbolt, and in figure, voltage-stabiliser tube 127 just has electric current to pass through.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 as can be seen from Figure 1 three end output voltages, (only differing from a PN joint), and when design, pressure drop on adjusting resistance 128 only has 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 is surely three end integrated circuits, so its voltage regulation performance can not be affected.The 2nd,, because the pressure drop on resistance 129 is mainly that output current by three end integrated circuits provides, 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 presses Circuit tuning to be comprised of resistance series arm (128 and 129 series arms in figure); do not contain easy failed part voltage stabilizing didoe, not fragile, three; design " special substitutes " protected mode branch road in the protection of the lightning protection third level, further improved reliability.

Also have following outstanding advantages after the invention process:

1, mobile phone can receive the communication signal of radio net reliably, when receiving signal, the vibrating effect that it sends, the excited vibration transducer is reliable, the timing feedback circuit is to make discrete vibration sensor signal become the reliable available signal of telecommunication, new compound sensor electric property is very good, extremely is suitable for the receiving system that opens the door as a kind of phone, also can be used as other long-distance remote control simultaneously.Be a bit in addition, be not subjected to the restriction of mobile phone model, the weak mobile phone of the strong still vibration of tube vibration all is not suitable for.

2, mobile phone is a complete integral body, can make the reception part of signal transducer, also can be used as mobile phone and independently uses, and the mobile phone utilance is high.Simultaneously, to using mobile phone 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 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.

4, strong security, mobile phone can not be dialed by the stranger after packing in box, can not produce and steal the cell phone password situation by caller identification, and O﹠M is very convenient.

5, practical, only to manage mobile phone model of a great variety, but all be suitable for, this is the call signal that vibrating sensor can take out the disposable type mobile phone, the 2nd, after external electric supply socket adopts USB socket, have very strong universal meaning.

6, adopted the dress box of mobile telephone after, its box second box A that can also pack into, the relevant electronic device of packing in the second box A is with circuit board, so whole standard in the installation box.

7, because the present invention has adopted excellent power supply adapted with it; General Promotion the performance of integral body of the present invention; embody in the following areas: 1, performance is good; embody in the following areas: the one, anti-thunder is effective; has the lightning protection three-level protective; at thunderstorm season, not fragile, supporting electrical equipment needn't quit work at thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply, wider adaptive capacity is arranged, be namely to make the protector of joining work and be unlikely damage when the high place of voltage and period or accidental cause, and also can work 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 to 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.

8, reliable.Reason one is that in electronic circuit, voltage stabilizing didoe is also 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 in the present invention, and reliability generally all is much higher than common triode.

9, debugging is convenient, easily batch production.
