Description

A kind of timing transducer that contains the overvoltage backup

Technical field

The invention belongs to an industry technical field.

Background technology

With phone, realizing the remote opening door operation of door, 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 it is supporting with it that this patent need to a kind ofly receive the transducer of distant signal, and this transducer should meet following requirement:

1, on electric property, want to receive the signal that long distance network is notified from a phone call, 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 the current automated production of door industry, there is no satisfactory transducer.Consult existing pickoff spare, also do not have a kind of transducer can directly meet above-mentioned 3 requirements.

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 be easily from receiving remote call signal communication network, but they are outside output signal directly, by traditional method, all must again process, as the two ends from loudspeaker, draw signal, but do like this integrality that can affect mobile phone, and easily cause the damage of mobile phone, also be difficult for batch production.

3, mobile phone will be in continuous duty, and mobile phone need to be changed battery, in case, a little less than electricity, work undesired, the battery maintenance method of changing by traditional, increased a lot of additional work amounts, is difficult to guarantee that mobile phone can be in the state of good reception at any time.

If 4 adopt external power supply to replace the mobile phone accumulation pond, allow the mobile phone long-term work, but now a lot of mobile phones are all to adopt a jack, this jack is namely the external charge jack, it is again the insert earphone jack, and the external charge socket that namely needs required for the present invention needs again the jack of call signal, conflicts.

5, because the starting of reporting to the police is the key element of alarm, whether reliably he be directly involved in starting, or no malfunction arranged.Show after deliberation, address this problem, must aspect machinery and two, circuit, make an effort simultaneously, cooperatively interact, the effect that just can obtain, but to use what kind of mechanical structure, and what kind of circuit of joining be only best processing method, this is also an important topic that is worth research.

6, invention is a kind of special application product, because its Main Function is to realize that phone opens the door, it should be in a kind of armed state at any time, is namely to be at any time normal operating state, otherwise can not opens the door, directly impact life.Obviously supporting with it with the Power Management Design of ordinary electrical home appliance is to be difficult to reach such purpose, its reason one is that ordinary electrical home appliance can not worked when thunderbolt is arranged, can avoid damaging, the 2nd, within ordinary electrical home appliance work can only be operated in common standard, when exceeding standard, easily damages civil power, when low, work and cisco unity malfunction, the working range surplus is little, limited the scope of application of the present invention, the 3rd, the present invention is furnished with storage battery, must carry out scientific maintenance, otherwise fragile, the 4th, power supply is flimsy parts in electrical equipment, in case damage the maintenance difficult of asking someone, and consequence is serious, therefore want what kind of design, could requirement according to the invention.Also become a difficult problem.Because causing this quality factor of the deficiency of first aspect is the inherency deficiency of three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series), the voltage of input can not be too high, is generally 30 volts.And have the input of three end integrated circuits while being struck by lightning may surpass this value.Cause the reason of which aspect deficiency to be, 220 volts of civil powers are become to the bridge rectifier voltage output value after the required low pressure of electronic circuit, can only meet city's electric standard of most applications, when the high place of civil power and period, its bridge rectifier output just may surpass the amount of imports definite value of three end integrated circuits.For addressing this problem, conventional method is, after bridge rectifier before three end integrated circuits, newly increase the one-level emitter follower, its objective is, after the bridge rectifier overtension, allow emitter follower will export pressure limiting, make this not surpass the rated voltage of three end integrated circuit inputs.Although such scheme has been expanded the higher limit of bridge rectifier output, but has produced new contradiction, because newly-increased emitter follower can produce the supplementary loss voltage drop.When civil power was low, three end integrated circuits likely can be worked, but because there is the additional electrical pressure drop in the emitter follower increased newly, and three end integrated circuit input ends will step-down, lower than desirable value, and just can not voltage stabilizing.The reason caused is, because the output valve of circuit of three-terminal voltage-stabilizing integrated is a certain integer value of fixing, and as 5 volts, 8 volts, 12 volts, the float charge voltage of the fractional value of can't satisfying the demand, as 3,7 volts, 12,6 volts, etc.More seriously, in present existing design, be difficult to solving float charge voltage needs high and contradiction that electric discharge is forced down.Due to the problem that can not effectively solve above-mentioned three aspects, so easily damage, this has just caused next aspect problem easily to produce, in case be namely to damage, maintenance is difficulty again, affects phone and opens the door, directly impact life.The stabilized voltage power supply of joining in addition, also relates to many-sided problems such as cost and reliability.

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

2, to lay one of place be on door to transducer integral body.

3, the electronic timing self-lock switch is the self-locking form formed with two triodes.

4, in the voltage transitions adaptation, emitter follower base stage voltage-stabiliser tube power is 1W, and on base stage, inclined to one side resistor power is 0.5W.

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 after the calling of phone, just can send the instruction of opening the door outside it receives room.In the present invention, mobile phone Main Function used receives the use of mobile phone outside room (" key " mobile phone) calling exactly.But mobile phone but can not directly be exported the needed signal of telecommunication.This is one, and it two is that present mobile phone many types are all to only have a socket, this socket both had been used as the insert earphone socket, do again the mobile phone external charging, and this series products of the present invention needs two external sockets of control signal and charging simultaneously, conflicts.And the present invention proposes the problem that additional mobile phone spininess socket can solve this respect well.

Two, the structure of the additional mobile phone spininess socket in the present invention is as shown in figure mono-, its inside has a lot of positions to patch the little electric conductor that is connected, after additional mobile phone spininess socket inserted the mobile phone external socket, in these front ends that patch the little electric conductor that is connected and mobile phone external socket, each exit patched to contact and is connected.Rear end is the jack shape, can correspondingly insert a contact pin, and the front end of contact pin inserts in aperture, and rear end is the outer lead-out wire of connection socket.Because contact pin can separate with jack, also can patch combination, so can adjust flexibly the position in the contact pin place socket after line.Thereby can draw easily and respectively organize data wire in the mobile phone external socket.In the description of rear Fig. 1, why each contact pin does not insert little jack, shown that exactly each contact pin can insert the little jack of optional position, this is one, it two is that each contact pin is the same with little jack structure, has also shown again from an aspect that the position that patches of every contact pin is flexible and changeable.Because be such structure, so only manage mobile phone, Multiple Type may be arranged, only manage the position that the exit of required signal may be in external socket different, but by the flexible adjustment position of contact pin, all can draw the holding wire of required insert earphone, with mobile phone external charging lead-out wire.And the former introduces control circuit, latter can add the mobile phone external charging source.Because the additional mobile phone spininess socket proposed in the present invention has such structure, so, with additional mobile phone spininess socket of use of the present invention, can draw easily two groups of data wires in mobile phone, and can not damage mobile phone.

Three, electronic self-locking circuit has played important function in the present invention, its Main Function has 2 points, one of, relaxed the requirement to mobile phone, mobile phone no longer is subjected to the restriction of model, no matter be that the ring size can be extracted signal reliably, two are sensitivity and the reliabilities that improved emission, the enhanced signal amplification quantity.Its reason one is, because principle of the present invention is, when mobile phone one has signal, will send the warning initiating signal, starts immediately the radio remote-controlled circuit starting, allows receive produce a phone enabling signal; Latching circuit starts immediately, and irretrievable, will send initiating signal.Its reason two is that owing to being security personnel's products, its wireless remotecontrol is all to adopt the multi-code transmitter circuit, needs the regular hour when emission, if without this circuit, in some cases, does not just likely guarantee the so long time.And this circuit has been arranged, just can guarantee that the emission of starting each time is all very reliable.

As follows to this line description:

One of 1, the form to the pipe amplification that adopts NPN and PNP to constitute jointly, have following meaning,, amplification quantity is large; Two, the PNP pipe become saturated after, the loss of voltage of generation little (when being furnished with storage battery, peculiar meaning); Three, can easily transient signal be changed into to a kind of long signal; Four, formed electronic switch volume urine is in miniaturization.

2, in the electronic switching circuit that pipe is formed, anti-remaining resistance, namely that the resistance connect between PNP pipe emitter and base stage has played important function in circuit, its effect is when NPN pipe no signal, the thorough no-voltage of the output of switch, output, without any remaining electricity, for the through engineering approaches that electronic switch uses, has been created essential condition.

3, why between two pipes, add the positive feedback with Capacitance derivative, the one, meet this condition, the 2nd, can realize automatic recovery.

4, why feedback capacity adopts electrodeless reason to be, the electrodeless electric capacity leakage coefficient is little, under at feedback circuit, circuit is more stable.

Four, 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:

The first, measure summation: made the modified model of emitter follower by one of them NPN triode, the float charge voltage of output science; The power supply of work system is provided simultaneously when civil power is arranged, is subjected to city's electric control with a PNP triode, to the automatic switchover of floating charge and electric discharge, make to export and do not produce the drop of 1,4 volt.

The second, voltage stabilizing circuit pack and the characteristics in power circuit mainly illustrate:

(1), output voltage can be adjusted into arbitrarily the required normal voltage of floating charge.Its principle is, the voltage-stabiliser tube of article one branch road in base stage (be namely base stage through road that voltage-stabiliser tube is connected with resistance) can be realized the coarse adjustment of output voltage, and resistance can be realized accurate adjustment.It should be noted that, why resistance can realize that the reason one of accurate adjustment is that the ratio that accounts for of the pressure drop of this resistance is little, the 2nd, designed output end of pressure-stabilizing and provide electric current by Zhi Luxiang this resistance of diode and resistance string, and this branch current accounts for and leads part in the electric current of this element.The 3rd, between this element and ground, be connected to integrating capacitor, to avoid the transition of this point voltage; So in the fixed situation of other component parameters, adjust the size of this resistance value in this circuit, with regard to pressure-adjustable, rule is that this resistance value is higher, and voltage is higher, otherwise lower.

(2), have voltage stabilizing backup and automatically drop into protection circuit, greatly improved circuit reliability.As everyone knows, active of electronic circuit (being namely triode in circuit and voltage-stabiliser tube etc.) belongs to easy failed part, this circuit in the present invention, and anti-exactly voltage-stabiliser tube damages and designs.Between this route base stage and ground, institute's voltage-stabiliser tube that connects is called for short the second branch road after forming.Its principle is that base stage is to the low PN joint of first branch road pressure drop ratio the second branch road left and right, by the second branch road clamper when normal operation.So the second branch road does not produce " electrical wear ", can not damage.Its meaning is as follows: one, after the voltage stabilizing in the first branch road damages in the course of the work, the second branch road voltage-stabiliser tube conducting immediately, although variation has occurred in now voltage stabilizing value, many PN joints, (three end integrated circuit circuit, error amount is 0,5 volt), but due to output remain voltage of voltage regulation, on the electrical equipment of joining substantially without affecting.Two, when thunderbolt was arranged, the first branch voltage increased, and the conducting immediately of the second branch road forms shunting, has alleviated the load of the first branch road, and the first branch road is not fragile, has strengthened the reliability of the first branch road.

(3), have three layers of factor protection, so lightning protection is good.The one, triode used is high back-pressure high power valve, and its back-pressure parameter is (three end integrated circuits input voltages are only 30 volts) higher than 78 serial integrated regulators more than 10 times; The 2nd, anti-thunder tube is housed.Three be to have voltage stabilizing backup automatically to drop into protection circuit.

(4), in the higher place of civil power and period, can not damage the reason of circuit.Adjusting pipe is high inverse-voltage tube, and back-pressure is three ends more than 10 times, by far away higher than the integrated regulator of 78 series.

(5), the reason that can work on the lower ground of civil power.The one, because adjusting pipe, be high inverse-voltage tube, can design the bridge-type output voltage higherly, when civil power is low, just can do certain compensation.The 2nd, output voltage adjustment pipe of the present invention, can not produce the additional electrical pressure drop, and it directly is adjusted into electric power output voltage by the bridge rectifier output voltage, be namely to need only bridge-type voltage higher than output voltage, and this voltage can make triode work, just energy voltage stabilizing.(illustrate: if the design that adopts traditional triode to connect with three end integrated circuits, so work that three end integrated circuits will be stable, voltage that just 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 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).

(6), overcurrent protection principle: when output current is excessive, adjust the resistance drop increase that the pipe emitter is connected, the diode current flow in the overcurrent protection branch road, base current minimizing, the automatic adjusting.

Due to above reason, thus this circuit with 78 traditional serial integrated regulator methods for designing, compare, the many index excellence.

Three, the explanation of the floating charge in power circuit:

This part mainly consists of jointly floating charge resistance, electronic switching tube (PNP pipe), peripheral assembly and balance diode.

Because the NPN triode has been exported the floating charge normal voltage, so the floating charge science.Floating charge resistance mainly contains two functions, and the one, to large current limitation, the 2nd, realize the voltage isolation between AC voltage-stabilizing floating charge output point and storage battery, thereby when interchange is arranged, namely can floating charge, can become operation source again.

While four, scientifically solving the storage battery floating charge with electric discharge, there is the explanation of the problem of larger voltage difference:

When the electronic switch be comprised of PNP triode and peripheral element can successfully solve the storage battery floating charge, battery tension was high, and electric discharge is forced down, both inconsistence problems, and its principle is: this pipe base stage resistance to earth is subjected to the control of bridge rectifier output.The composition of this circuit, just formed such principle, when the bridge-type output voltage, shown and now had alternating current, storage battery to should be the floating charge stage, at this moment the operating state of switching tube PNP pipe is, its base stage has voltage, and PNP pipe can conducting and become closed state, when when bridge-type is exported no-voltage, PNP pipe base stage does not have auxiliary voltage, and the electronic switch that the PNP pipe forms becomes opening state.Storage battery is discharge condition.So just distinguish reliably two stages of floating charge and battery discharging.Should heavily point out, this pipe PNP pipe is not only a state control switch pipe, has distinguished floating charge and electric discharge two states, and the very important point is that storage battery is while being in discharge condition, this pipe is in saturation condition, and the voltage fallen is very low, can not lose the most valuable pressure drop of storage battery.

Five, alterating and direct current is mixed the explanation of the voltage principle that output quality is good.

The effect of balance diode assembly: because AC voltage-stabilizing output is 13,5 volts of float charge voltages, through after two diode step-downs, reduced to again about 12 volts, because dynamic resistance of diode is little, little to load effect, do not produce the output voltage fluctuation, so guaranteed to exchange the correctness of output.And, when storage battery power supply, without this part, only through discharging and recharging electronic switch, do not produce pressure drop.

With regard to power supply, this beyond above-mentioned multiple performance, this power supply also has core be a bit active few, thereby bring reliable, cost is low, circuit is simple and easy to produce a series of advantages such as easy debugging.

Five, the voltage transitions adaptation is as the mobile phone voltage-reg-ulator tube from emitter follower of power supply 12 volts of terminations of output, because the emitter follower base stage has 5 volts of voltage-stabiliser tube voltage stabilizings, so the output of emitter follower is hanged down PN utmost points than 5 volts, then makes balance with diode, reaches the requirement of 3.6 volts.

Following outstanding advantages is arranged after the invention process:

1, mobile phone can receive the communication signal of radio net reliably, and while receiving signal, remote control performance is very good, and the insert earphone signal of telecommunication of output is very reliable.So, extremely be suitable for the receiving system opened the door as a kind of phone.

2, mobile phone is a complete integral body, can be used as transducer of the present invention, also can be used as communication handset and independently uses, and the mobile phone utilance is high.With machine, without secondary operations, can not cause the damage of mobile phone.

3, 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 if adopted base) that is not subjected to environment, do not affect attractive in appearancely within doors, for its people, do not know, to the secret benefit of all bringing yet.

4, strong security, mobile communication password are 11, and often conversion.

5, have very strong operability, practical, only manage mobile phone model of a great variety, but all be suitable for.

6, relax the requirement to mobile phone, be not subjected to the restriction of model.

7, enhanced signal amplification quantity, make emission sensitiveer reliable.

8, 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: the one, lightning protection effect is good, at thunderstorm season, not fragile, supporting electrical equipment does not quit work because of thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply, wider adaptive capacity is arranged, be namely work and be unlikely to damage when the high place of civil power and period or accidental cause, and also can work in the lower place of voltage and period.The 3rd, can be used for exporting the voltage stabilizing value that there is decimal in generation.Thereby can the required voltage of floating cell.Storage battery is not fragile, and the life-span is long.The 4th, simple in circuits is easily gone, and excellent performance, have overvoltage and overcurrent protection.The 5th, particular importance be a bit no matter at floating charge state, or, having a power failure the period, all keeping good performance.

9, can easily reach the required magnitude of voltage of mobile phone, can not damage the interior of mobile phone element because of overtension.
