6, in modular power supply 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.

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

In the common communication telephones in market, generally all have a number storage function, the telephone number that is with often puts through of the argument of this function of telephone set design is easy to use, 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 element, with it, replace traditional manual dial's mode.

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, except having adopted love notice operating part, also have two kinds of electronic circuits in telephone set.A kind of is the radio reception circuit, and it can transmit from the wireless remote control that the user sends by reliable reception; Another kind of part is a kind of electronic program circuit, the logic function of this programme control circut is, can be by the extension line 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 to a mobile phone of 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 transmitter, in a single day receiver receives signal, just can send instruction, allows 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.

Two because people when the accident may have distance with telephone set, can't take receiver, but now because the program-controlled unit starting, telephone set is in hands-free duty, thus can give orders or instructions without receiver, and box can will be passed to the telephone set of hands-free operating conditions after having increased the audio amplification circuit unit again after the amplification of meaning epigenesist sound 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.

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

5, adopt 4066 integrated circuit, 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 extension line 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 principal feature: adopted traditional three end integrated circuit to make the last output of voltage stabilizing.Before three end integrated circuit inputs, increased the one-level emitter follower and made impact damper, but the design proposal one different from tradition is during this grade normal operation, not contain consumable accessory zener diode, good reliability.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 circuit, 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 by thunderbolt is in the scope of tens of volts of voltage breakdown.Three be to have increased " lightning protection overvoltage backup " circuit in the base stage that output voltage is adjusted pipe, (stabilivolt 327 branch roads in figure), the duty of this pipe is, be at ordinary times the no current conducting state, its reason is that in circuit, selected stabilivolt 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 end 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, (stabilivolt 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), in the higher place of civil power and period, can not damage the circuit explanation.Its reason such as back and forward, thunderbolt are a kind of reasons of overvoltage.The lightning protection circuit effect, be 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 to compensation like this.Therefore expanded the civil power lower range.

(5), can expand the explanation of civil power variation range.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 and adjust the adjustable peripheral circuit of voltage stabilizing value, 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 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 with resistance, is connected between its earth terminal and ground connection, the resistance of similar resistance is not easy to produce the consistance 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, in diode and resistance series arm, occupy larger specific gravity, 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 diode 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 diode, and this stabilivolt 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 diode is a kind of easy failed part, particularly is used in the power supply local (stabilivolt 327 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 diode, the principle formed is, newly-increased emitter follower base is pressed Circuit tuning, when normal operation (be namely groundwork path) is 328 and 329 series arm in figure, rather than " lightning protection overvoltage backup " branch road, not namely 327 stabilivolt 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, stabilivolt 327 just has electric current to pass through.What also should illustrate simultaneously one is, 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 circuit, because this circuit output essence is surely three end integrated circuit, 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 circuit 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 impact damper base presses Circuit tuning to be comprised of resistance series arm (328 and 329 series arms in figure); do not contain easy failed part voltage stabilizing diode, not fragile, three; in the protection of the lightning protection third level, design " special substitutes " protected mode branch road, 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 with the other side, converse.

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 far and near relatives are, 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 robotization 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, can place in room more, and factor of assurance 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, 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; 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 supply, wider adaptive faculty is arranged, be namely to make the protector of joining work and can not damage when the high place of voltage 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.And the existing achievement of inventor is security personnel's classes, need to be to the floating charge circuit of accumulator, this circuit can not be round values.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.
