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

The inventor has done to study for a long period of time to anti-theft safety door, and anti-theft safety door has arrived the stage of following progress:

The firstth, normal door is opened the door without mechanical key, but the mode of opening the door with electronics telecontrol engineering or phone.When normal door, be installed on the propulsion system in door, will promote the lockset action, realize opening the door.Meanwhile, still kept the form that mechanical key opens the door, its objective is to have a kind of opening the door to make up when automatic system goes wrong.This is namely if open the door with mechanical key, and great majority are to want to be also the situation that needs telephone call by joining the situation of mechanical key crime.And a few cases is own oneself to want the situation of opening the door with mechanical key because electrical equipment goes wrong, but this situation is own clearly situation on the scene, produces alert sound oneself and does not also feel fearful and nervous.

The secondth, have identification circuit, can correctly identify is the situation of crime behavior or owner's normal door.Its reason is that the behavior of opening the door normally is to open the door with electronic technology, rather than opens the door with mechanical key.When normal method was used electronic open-door, the identification circuit input had electronic signal, and the input of crime behavior identification circuit will start warning system without electronic signal.

For this reason, existing meaning to each technical measures of the present invention, concrete condition further is explained as follows:

The switch of one, pacifying in measure scheme one is the key component that warning of the present invention starts, and is also a bright spot of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, warning of the present invention having been accomplished more scientific, is also the place different from a lot of alarms, and its reason is:

The one, can generation not make us terrified wrong report, this is the most important.Its reason is, the use ' key ' that is absent from the scene of owner is opened the door by lockhole within doors, is the crime behavior, and the warning of this moment is very significant.

The 2nd, very reliable, because the opening the door at closing time of normal life, do not need artificial additional move, do not affect the normal habits and customs of people, thereby do not affect the normal operation of the each starting of security system.

The 3rd, protection is tight, is no matter to force open the door or the perpetrator wants to get started by cracking lockhole with barbarous mode, all can produce warning.

The 4th, the warning starting switch is sensitive and reliable, can just report to the police when the crime behavior is not accomplished, thereby loss is reduced to minimum.The coverage of dry-reed tube switch and magnet only has 3 centimetres, be subjected to displacement at door and doorframe, or lockhole cap is when loosening, and the lockhole switch contact initiating signal of reporting to the police that will change.

Two,Be positioned on the warning starting in door, telephone call adopts wireless remote control to contact with being placed within doors, so telephone call is laid a little arbitrarily, has strengthened confidentiality.

three, dialing integrated circuit chip in the present invention in the information processing part is following function, the one, can store a plurality of telephone numbers, in the situation that oneself stores complete in advance, (the present invention can utilize former existing phone that this integrated circuit is stored), as long as being stored pin, it adds a trigger pip, this sheet will automatically be controlled and send a phone number dial, so its a plurality of storage number ends have been connected on respectively on a plurality of output terminals in a sequential circuit cell, the dialing output terminal of this integrated circuit has been connected on telephone set, so when the starting telephone call, the multi-section telephone number that a plurality of output terminals of programme control circut can start this element storage outwards dials.The models of a lot of dialing integrated circuit have powerful storage number function, and a lot of integrated circuit storage capability are all at 10 more than number, so telephone alarm function is very powerful.

Four, the program circuit in this unit can be made of a variety of circuits, and the Copper Foil that the Hands-free key of the telephone set in its first output terminal and this part is corresponding is connected, other output respectively with the dialing integrated circuit in multidigit store pin and be connected.The program control rule that forms is that at first the first output export the Hands-free key of the high-order support machine that puts telephone lines into operation, and produces the off-hook program, then trigger the first storage number pin in the dialing integrated circuit chip; Call out the conversation of First receiver; As method repeatedly, can call out all receiver numbers that this sheet is stored.

Five,Report to the police to start owing to having adopted in technical scheme one, the two-part combination closely of telephone call, just formed such defence program and protection philosophy, when normal the anti-theft security door knob other people keep outside the door.When having the people to force open the door by barbarous mode, when door separates with doorframe, the dry-reed tube switch contact that is loaded on door and doorframe junction changes and produces alerting signal; When committing a crime by lockhole, in case open lockhole cap, the lockhole switch contact that is loaded between lockhole cap and door changes and becomes the signalling state; Identification of lines through this bright person in being fruitful is concluded whether this warning.Report to the police if belong to, can produce two functions, a kind of function is the alert acoustic-electric of connection promotion source, produces onsite alarming, and caution is caused at the scene, prior a kind of function is to be positioned on the controlled emissions plate radiating circuit starting of antitheft door part, after the reception dress is received and is transmitted, the warning that produces the multi-section phone, the owner of notice mobile phone, in time determine, with processing.Loss is reduced to minimum, or make up.

Six, the timing feedback circuit has played vital role in the present invention, and to this, circuit has following explanation:

When not receiving signal, first transistor collector is high-order, and the current collection of second triode is very low, not output signal.

when on off state changes, signal has been sent to first triode NPN base stage, this moment, current collection was very low, second transistor collector is high, output signal, meanwhile, the positive feedback branch that forms due to electric capacity acts on simultaneously, first transistor base has been added positive feedback voltage, no matter whether there is signal to be input to the base stage of first triode, second transistor collector is always high, signal output is arranged all the time, after having arrived certain hour, the feedback branch Capacitance derivative is full of electricity, feedback branch lost efficacy, so positive feedback is regularly, not eternal.

For this circuit also should illustrate following some:

So 1 will add positive feedback branch, 2 meanings are arranged, (1), relaxed requirement to switch, namely that switch can be key type, can be also button-type, and on the power of contact without impact, so can adopt miniature, the difficulty of installing to reduce switch increases the attractive in appearance of door simultaneously.(2), sensitivity and the reliability of the starting of reporting to the police have been improved.Reason one is, because principle of the present invention is, when its people has the action that cracks lockhole (referring to unclamp the behavior of the screw on the lockhole upper cover plate); switch has produced displacement, the action of lockhole protection switch, and latching circuit starts immediately; and irretrievable, will send initiating signal.

2, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and this moment, the second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe is fed back the charging of feedback capacity differential, until differential finishes.Second aspect is that the rejuvenation of feedback is reliable, when first transistor base is input as when low, namely second triode when full, the positive pole of feedback capacity is connected to the ground rapidly, by saturated triode, ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, fully can satisfy the necessary preparation of feedback next time.

3, feedback capacity is little has formed charging rate altogether with feedback resistance, adjustable flexibly, is adapted to dissimilar switch.

4, in feedback branch, electric capacity selects electric capacity capacious, the debugging surplus is larger, that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but select electrodeless electric capacity capacious, sometimes be difficult for looking for, and price is higher, so proposed to become electrodeless method with electrochemical capacitor, chosen the method that the negative pole of having used two electrochemical capacitors is connected together in figure, after adopting this method, capacitance can conveniently make up, and leakage coefficient can improve a lot of a lot, in this programme because the positive feedback circuit is arranged, to the stability of raising circuit highly significant.

5, to have added the reason of diode be when on off state changes, when signal has been added in the base stage of the first pipe, not produce loss of signal branch road to positive feedback branch.

Seven, power supply is an emphasis of the present invention, is directly connected to performance of the present invention.The specific explanations of circuit is as follows:

1, the cardinal principle of voltage stabilizing:

The adjustment triode has adopted to be penetrated with output, and very strong negative feedback is arranged, in case after line parameter circuit value is determined, adjusting triode just can be stabilized on a concrete numerical value, and can satisfy the requirement of equipment, if it is less to adjust the upper inclined to one side resistive arrangement of triode, its with power also very large.

2, the reason that has good anti-lightning effect: when thunderbolt is arranged, usually that power supply is perishable the time, that take the to cut off the power supply mode in source is avoided as common household electrical appliances, but the specialities as security personnel's class, will become security personnel as resolute power down source blank, so improving lightning protection effect is an emphasis of the present invention, the present invention has taked following some effective measure for this reason.

The first, adopt active controllable silicon to form " fast tripping protection function ", excellent performance has very strong lightning protection overvoltage capabilities.

This element is namely (111) the part controllable silicon in accompanying drawing 1, and the peripheral part that triggers: stabilivolt (110), resistance R 4(109).The principle that forms is: if thunderbolt and when causing output terminal too high and after surpassing the door of diac; silicon controlled trigger element stabilivolt (110) conducting; thereby triggering controllable silicon (111) conducting; immediately to adjusting the base stage short circuit of triode (103); cause to be closed adjusting triode (103) output voltage, form lightning protection overvoltage fast tripping protection.Why be called " fast tripping protection ", in case be because output terminal when too high, controllable silicon leads that (111) are logical has a very strong positive feedback, can will adjust the base stage short circuit of triode (103) rapidly, forms " fast tripping protection function ".And after output was normal, after can not puncturing controllable silicon (111) with no pressure, controllable silicon anode dead electricity was recovered automatically, if again be struck by lightning, again started, and formed protection, until output voltage is normal value.

The second, " the fast tripping protection function " of this active formation is in " open-circuit condition " when work, just works when needing only thunderbolt or overvoltage, so be not easy to damage, all is in a kind of guard mode constantly.

Its reason is power output end when being normal condition, and controllable silicon is in off state, there is no " electrical wear ", can not damage.And its external trigger is enclosed part stabilivolt voltage stabilizing value higher than output end voltage, so also be in open-circuit condition, there is no " electrical wear ", also can not damage, and all can be at any time a kind of " armed state ".

Three, adjusting triode is high inverse-voltage tube, and lightning protection effect is good.

Its reason is, this pipe oppositely suctions through voltage usually at hundreds of volts, and 78 serial back-pressures are generally 30 volts.To exceed more than 10 times than 78 series commonly used.

Four, be equipped with anti-thunder tube, this pipe voltage breakdown is tens of volts, after high inverse-voltage tube coordinates, thereby has very large surplus.

3, form the overcurrent protection principle: when output current is excessive; the resistance R 3(that the adjustment transistor emitter is connected is overcurrent protection resistance) the pressure drop increase; when surpassing certain value; diode current flow in the overcurrent protection branch road; flow into output voltage and adjust the base current minimizing of triode; load overcurrent is super many, and the base current that reduces is more, automatically forms adjusting the triode protection.

4, can produce meaning and the reason of overcurrent protection indication: general device breaks down; overcurrent condition accounts for significant proportion; particularly when overvoltage active impaired the time, and overcurrent must react on power supply, so be power supply accurately as the monitoring point.If it is also that positive effect is arranged that overcurrent has demonstration, because one have demonstration, show that this equipment or instrument have fault, both carried out " Rough Inspection ", improved maintenance efficiency.The reason that can realize the overcurrent indication is; during overcurrent; the base flow shunting of adjusting triode will be flow through light emitting diode; lamp is bright; so this diode is complex function, the one, utilize its function that has PN economize on electricity to press, allow it with after overcurrent protection resistance R 3 coordinates with it; realize overcurrent protection, the 2nd, utilize its luminescent properties to realize the overcurrent indication.

5, can not damage the reason of circuit in civil power higher place and period: be high inverse-voltage tube because adjusting triode, although the voltage of bridge-type output this moment is high, also can be far below the high inverse-voltage tube withstand voltage.

6, can be in the main cause of the lower place of civil power and period work: the one, the adjustment triode in circuit can not produce the additional electrical pressure drop.(illustrate: if the raising input voltage scheme that adopts traditional triode to connect with three end integrated circuit, for triode and three ends can be worked, the one, give the voltage of three end integrated circuit input ends higher than output terminal, the 2nd, be to the operating voltage of triode needs, main product has been given birth to triode supplementary loss voltage like this, and when civil power was low, this was valuable voltage.) it two is to be high inverse-voltage tube because adjusting triode, so can design the bridge-type output voltage higherly when design, when civil power was low, at this moment bridge-type voltage can not be very low, just can do certain compensation.

7, can expand the reason of civil power variation range: due to upper two reasons, do not damage circuit when civil power is high, and still can work when low.So can expand widely the working range that civil power changes.

8, can adjust the reason of different output voltage stabilizing values.In reference voltage the first branch road, the pressure drop of stabilivolt is leading role, so can form coarse adjustment, and the shared ratio of the resistance R 2 of going here and there is very little, so also can do the use of accurate adjustment, the benefit of accurate adjustment is can the furnishing normal voltage required to the accumulator floating charge, as 6.6 volts; 12.8 volt etc.

After the invention process, the anti-theft security goalkeeper presents a kind of brand-new looks, and following outstanding advantage is arranged:

1, supporting power source performance is good, shows following several respects:

(1), anti-thunder and overvoltage protective property are excellent.The one, because " fast tripping protection " that this protection circuit forms is highly sensitive, because controllable silicon has very strong positive feedback ability, in case output end voltage is too high, surpass the diac threshold voltage, controllable silicon moves immediately.The 2nd, protection is large, because immediately output end voltage is clamped substantially zero after controlled silicon conducting; The 3rd, have automatic protection and auto restore facility, thereby protection system is in Status of Backups all the time when overvoltage not, do not produce electrical wear, its largest benefit is unexpected few, reliability is high.Because overvoltage protective property is good, so when thunderbolt, the equipment damage probability is few, can cut off the power supply.This is even more important for a lot of specialities.

(2), compare with common source of stable pressure, the present invention has monitoring function, when overcurrent appears in circuit, the indication of LED light is arranged.Can find rapidly like this damage equipment in the multilevel signal amplifying circuit, improve maintenance efficiency, the present invention can monitor at any time and understand the standby duty that sets, and has improved reliability.

(3), adapt to widely, than traditional stabilized voltage supply, wider adaptive faculty is arranged, be namely can make the electrical equipment of joining at the high local work of voltage and unlikely damage, and also can work in voltage lower place and period.

(4), can be used for exporting generation the voltage stabilizing value of decimal arranged, be convenient to the floating charge of accumulator science.The 4th,, excellent performance, have over-voltage over-current protection.Be fruitful supporting after, have good performance.And be difficult to realize with the co-design of three traditional end integrated circuit or traditional triode and three end integrated circuit.So the present invention has very strong ability to provide the auxiliary items, also can be supporting with other electronic products.

(5), the cost of the co-design of cost and traditional triode and three end integrated circuit, substantially do not increase, and cheap more a lot of than a lot of professional stabilized voltage supplys.

(6), simple in circuits, easily produce and debugging, reason one is because the debug point in circuit is few, and parameter is consistent, the 2nd, after the diode series connection is adopted in the debugging of protection system, suitable batch.

2, after the invention process; anti-theft safety door and alarm have been realized the combination of science; the advantage that has possessed two kinds of protectors; usually both can keep the people outside the door; when running into other people and committing a crime; can send two kinds of cautions; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will suppress the crime behavior generation; and whether waiting for passively its destruction) be all very significant, the situation of the passive defence of anti-theft safety door so this product is through with has fully promoted security personnel's performance of anti-theft safety door all sidedly.

3, the warning system partial properties is very excellent, is most valuable for alarm, embodies in the following areas:

The one, warning system can not reported by mistake fully.Because after existing achievement coordinates, has automatic recognition property.The warning that produces when owner is absent from the scene may be only the crime behavior.Otherwise the behavior of not committing a crime, the warning starting switch can not send signal, at this moment because the structures shape of switch is installed.Due to the intrinsic property of switch, when the distance of switch and magnet has surpassed 3 centimetres, the contact of switch must change.

The 2nd, reliable, its reason one is, the user is closing the door when opening without any need for other additional move, thereby warning system all is in a kind of " highly waiting " state at any time, do not need any preliminary work, the 2nd, the malfunctioning chance of mechanical switch is far superior to electronic component.

The 3rd, easy to use.Do not affect normal habits and customs after installation fully.If increased trouble with former life, the shortcoming of obviously bringing to the people is or is to use inconvenience, or forgotten necessary operation and bring the malfunction of warning or malfunctioning.

The 4th, on-the-spot and two kinds of warnings of phone are arranged, deterrent force is larger, and is used because both complementations respectively have.

4, single also have following characteristic with regard to telephone call:

The one, the warning great efforts, can store the multi-section phone, send out simultaneously mass-sending, such benefit one is to carry out Advise By Wire to a plurality of personnel, the 2nd, both can call out the mobile phone of taking with oneself generation, can call out the fixed line phone in relevant place again, can reducing to minimum to the various objective factors that are unfavorable for Advise By Wire, stop even fully.

The 2nd, the multi-section phone of calling out all can be known, stopped to only have limitation that a people knows with may be errorless.

The 3rd, the acknowledge(ment) signal person can hear language or the alert sound of warning, and can listen to the scene.

The 4th, easy production, the one, because report to the police part and telephone set unification, can save many circuit, as general off-hook element circuit, store the keypad of number etc., and the part that increases is very limited, the 2nd, element used all belongs to part commonly used.

The 5th, can accomplish a tractor serves several purposes, the telephone set after repacking is namely a kind of telephone alarm, but still has kept all properties of telephone set, still can be used as communication telephones, such largest benefit is that family does not have too much device ornaments and to affect family attractive in appearance.

5, the requirement to switch has been relaxed in the use of timing feedback circuit, reduces the difficulty that switch is installed, and has improved sensitivity and the reliability of reporting to the police and starting.
