Background technology

Present society, people are busy with one's work, and the time of going home is shorter and shorter, pays close attention to empty nest old man, is the responsibilities and obligations that we should use up.

Will know at any time the old men's situation, the best way of transmission of information is phone.

Are some old men in alone because of health, and while meeting accident, the old man may have with a certain distance from telephone set, so what kind of mode the old men will just can put telephone lines into operation by? will and put through the numeral of multidigit? how just can hang on conversation.

Because the present invention must adopt telecontrol engineering, and although present radiotechnics is very extensive, but its sensitivity can't reach requirement of the present invention, because the remote control distance of general application is closer, far away it doesn't matter, well-known remote control distance and weather, with thing ornaments within doors, (transmitted wave is had, do not cover etc.), all be relative, and less demanding field, be subject to these impacts, consequence is little, and if Ben Ming sensitivity is not high, can not overcome above-mentioned impact, just can not guarantee the reliable of reception, therefore what kind of receiving lines to be arranged, also become very large problem.

Electronic product 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 in the scope very wide at civil power, work, 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 while being struck by lightning may 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, 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 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, as 12.6 volts, Deng, also inconvenient when adjusting its voltage stabilizing value, 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.

For having a clear understanding of the meaning of the technical program, at first will make the following instructions:

In the common communication telephones in market, generally all have a number storage function, it is easy to use that telephone set designs the telephone number that is with often puts through of argument of this function, its reason is if after often dialling the number in advance and being stored in the storage key in telephone set, putting through while often dialing, a plurality of keys should be dialled and the mode of the code of long number could be transferred to, become and only press the simple and direct form that a key just can be transferred to the multidigit number, thereby use very convenient, because such characteristic is arranged, thereby created important prerequisite for the invention process measure 1, the present invention utilizes this characteristic exactly, in advance in phone, stored kith and kin's number, when accident is arranged, the old men can the operating and remote controlling box, after receiving element is received signal, rise and employ program unit, replace traditional manual dial's mode with it.

The meaning of abovementioned technology, concrete condition further is explained as follows:

1, radiating portion is to be carried by the old men in principle, is mainly in case unexpected.Meeting accident, they only need to click the simple motion of button just can launch, and due to simple to operate, more can not produce " science illiteracy ", thereby can start the love advising process by the simplest mode.

2,, in technical scheme of the present invention, in telephone set, except having adopted love notice operating part, also have two kinds of electronic circuits.A kind of is the radio reception circuit, and the wireless remotecontrol that its energy reliable reception sends from the user transmits; Another kind of part is a kind of electronic program circuit, the logic function of this programme control circut is, can be by the lead-out wire contact of 3 groups of buttons in measure one, at first the instantaneous Hands-free key of opening, then open and store button one key, after certain hour, close again Hands-free key, realize the open-minded of cycle for the first time, to realize the call of the mobile phone to being stored.And then again by similar program, open and store the second key, form the call dialing to second storage phone, iterative cycles like this, to automatic stop after certain hour.

In telephone set, radio reception circuit Main Function is the starting point that control to receive programme control circut, that is to say the old man with the signal that sends of reflector, once receiver receives signal, just can send instruction, allow receive programme control circut and start and start working.The function that receives programme control circut is stored telephone set moves successively except allowing, and can regularly stop simultaneously.Its connotation is, to will after closing the telephone set Hands-free key, no longer opening all storage keys certain the time, will realize the shutdown of telephone set and the automatic stop of whole control system.

3, this telephone set by the such reforming processing of telephone set process, do not relate to communication part, so still can be used as and can interrogate the phone use at ordinary times.

4, box is as follows by emission and acoustics circuit reason dimerous with oneself:

One of because carry-on box is to be with oneself, so when accident is arranged, or the old men and telephone set have apart from the time, can operating and remote controlling box replacement manual dial.

The wireless remote control emission adopts diode OR gate formula multi-code transmitter scheme, and important meaning is arranged, and main benefit is to be difficult for producing malfunction.And use now the apparatus of remote control many, as locking that car door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the many yards artificial disturbances that just can thoroughly stop afterwards this class.This circuit realizes that its principle of diode OR gate formula multi-code transmitter is; When the first end output of emission programme control circut is high-order, it is low that the inverter output connected makes the chip select of this coding integrated circuit of connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner only have corresponding section's chip select work.The 3rd, the 4th reason is the same.Due to each coding integrated circuit with or a door mode be input to modulating tube, so form the form of multi-code transmitter.

Two because people when the accident may have distance with telephone set, can't take receiver, but now because receive the program-controlled unit starting, telephone set is in hands-free operating state, thus can give orders or instructions without receiver, and box has increased behind the audio amplification circuit unit after can meaning epigenesist sound amplifying the telephone set that pass to again hands-free operating conditions with oneself, improved the effect of hands-free work, therefore the less sound of that fearness of the old men, after amplifying, can obtain effect preferably.

Can solve well while meeting accident the dialing of people's DR telephone machine and the contradiction of taking receiver so coordinate with main body of the present invention with carry-on box.

5, adopt 4066 integrated circuits, as telephone set lead-in wire and the interface circuit that receives programme control circut, following benefit is arranged:

(1), volume is little, because just include 4 electronic switches for one 4066, can make interface with 3 electronic switches wherein, thereby same function can only just can complete than the integrated circuit of small size with one, because the reception program control circuit is to be contained in telephone set, obvious whole printed circuit board area is less, is conducive to install.

(2), when the reception program control circuit is not worked, the electronic switch of 4066 IC interiors is not worked, the lead-out wire of telephone set does not produce any negative interaction to telephone set, telephone set can normal talking.And in reception program control circuit when work, produce correct logic to telephone set.

6, use the power supply of modular power supply as receiving circuit in the present invention, important meaning arranged, power circuit is described as follows:

(1), circuit totally forms and main feature: adopted traditional 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 level normal operation.The 2nd, thunderbolt (overvoltage) is had to three grades of strick precautions, overvoltage is taken precautions against effective.The 3rd, adopted 3 measures to make adjustable, the easy tune of three end integrated circuit voltage stabilizing values.

(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, this pipe design adopts high back-pressure high power valve, 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 by thunderbolt is in the scope of tens of volts of puncture voltage.Three be that the base stage of adjusting pipe at output voltage has increased " lightning protection overvoltage backup " circuit, (voltage-stabiliser tube 327 branch roads in figure), the operating state of this pipe is, at ordinary times in 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 (328 in figure and 329 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, do not produce electrical wear, so can not damage, guaranteed reliable when application.The 2nd, when input has high pressure; as thunderbolt; or the civil power accident is while having high pressure; in accompanying drawing 328 and 329 series arm pressure drops raise; at this moment " lightning protection overvoltage backup " branch road, (voltage-stabiliser tube 327 branch roads in figure), conducting immediately automatically; newly-increased emitter follower base stage is produced to pressure-limiting function immediately, implement protection.Due to the three-level protective formed thunderbolt, so when bad weather, needn't be to the disconnected power down of the present invention source, and can work.

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

(4) explanation of place that, can be lower at 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 to 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 adjusting of three-terminal voltage-stabilizing value.One of, be designed with three ends adjustment voltage stabilizings and be worth adjustable peripheral circuit, in this electricity routing diagram: 333,334,335 3 elements form.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of diode branch road in series with a resistor, 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.With diode, can address this problem, only the electric current of pipe inflow diode has the difference of size, and its pressure drop is 0.7 volt, so batch production need not be adjusted.But if 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, it is accurate adjustment.Three, in adjustable peripheral element, increase a road from three ends outputs branch road (333 figure), to strengthen easy batch production.Due to the electric current of this branch road, occupy larger specific gravity in diode branch road in series with a resistor, 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 334, 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 main thoroughfare and form principle.In traditional design, by 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 327 is 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 formed is, newly-increased emitter follower base is pressed Circuit tuning, when normal operation (be groundwork path) is 328 and 329 series arm in figure, rather than " lightning protection overvoltage backup " branch road, not 327 voltage-stabiliser tube branch road in figure yet.Because this branch road voltage stabilizing value is higher than 328 and 329 series arm pressure drop, during normal operation, by clamper, no current, only have accidental cause to wait the overvoltage reason as thunderbolt, and in figure, voltage-stabiliser tube 327 just has electric current to pass through.What also should illustrate one is simultaneously, in the design of the series arm 328 and 329, the pressure drop of resistance 329 is main, be essentially three end output voltages, (only differing from a PN joint), and when design, pressure drop on adjusting resistance 328 only has the three ten-day period of hot season, just can guarantee that the emitter follower output voltage meets 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 329 is mainly that output current by three end integrated circuits provides, rather than by the emitter follower base stage partially resistance 326 provide, so track stability and easy tonality are played to 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 (328 and 329 series arms in figure); containing 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.

After the invention process, antitheft door will present a kind of brand-new looks, and following outstanding advantage is arranged:

1, meet accident as the old man, and can't normally go to before phone while calling, the old man can be by the launch-box button of carrying, the love advising process of starting telephone set, allow and go home to visit away from oneself relatives, and the addressee can adopt base, also available handsets is collected mail number, due to portable mobile phone, so no matter the addressee is on duty or not closes outside and all can receive.

2, when meeting accident, if the old men are away from telephone set, after putting through telephone set, although, without earphone, still can conveniently converse with the other side.

3, the present invention adjusts flexibly, can store relatives friend's phone, also can store the phone of hospital 120, if what store is latter's signal, after the present invention's starting, can allow the other side know that the relevant informations such as address or characteristic of disease race against time by voice sheet.

4, function excellence.Embody in the following areas, the firstth, no matter local relatives are far and near, and he can receive call signal by the network platform.The secondth, the mode that the user adopts is called out the advanced person, in the situation that only pressed button No. one time, or during accidental falls, all may start the love program, and program will be carried out automatically later, and the user no longer operates.The 3rd is in calling procedure, to be two phone signals automatically transfering and stored, and sends in an alternating manner, if wherein a phone is not started shooting, another phone can receive.The 4th is in calling procedure, to be that two hands alternately and are repeatedly called out, if in this is called out, the situation that the line is busy is arranged, in inferior calling, can receive afterwards.The 5th be the other side after connection, both sides can converse, because what be now that phone opens is hands-free, can certain distance be arranged with phone.

5, simple and easy to use, only need press the button of launch-box once just, is all just automation later, will not produce " science illiteracy ", the simplification that has realized operating.

6, anti-unexpected good, the one, launch-box is small and light, can carry, the 2nd, just one of launch-box, can join a plurality ofly, in room, can place more, and safety factor is large.

7, after the invention process, telephone set still has all communication functions of phone, and a tractor serves several purposes does not increase ornaments and the apparatus of family, does not affect life and the custom of family, and family does not have too much ornaments and affects attractive in appearance.

8, be easy to produce, because utilizing a lot of circuit compositions in telephone set, relatively simple.

9 have stopped the interference of social various electrical equipment, make emission more credible reliable.

10, modular power supply used is as the power supply of receiving circuit, its benefit have following some: (1), performance are good, embody in the following areas: the one, anti-thunder is effective; there is 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 that in the time of can making place that joined protector is high at voltage and period or accidental cause, work can not damage, and lower place and the period also can work at voltage.The 3rd,, can be used for output for the voltage stabilizing value that decimal is arranged.And the existing achievement of inventor is security personnel's classes, need to be to the floating charge circuit of storage battery, this circuit can not be integer value.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.

(2), 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 to 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.
