7, the feedback capacity in the electronics latching circuit is to be connected into no polar form with two electrochemical capacitors.

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

Before this, the inventor studies antitheft door, and proposed normal door and opened the door without mechanical key, but the measure of the mode of opening the door with electronics telecontrol engineering or phone.Be when normal door, send instruction by remote control to the propulsion system that are installed in the door, 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 remedy when automatic system goes wrong, so antitheft door can be made lockhole semiclosed processing, its meaning is, lockhole is covered during normal the use, only during out of order special circumstances, just lockhole is covered sheet and is opened.

To above-mentioned measure, specific explanations is as follows:

One, it is reported, to the security personnel of family, the most important thing is the security personnel of opposite house, and the security personnel of opposite house, emphasis is again the security personnel to lockhole, because the great majority crime all is by cracking of lockhole entered house.For this reason, the inventor has covered cover plate above lockhole, Men Bulu lockhole at ordinary times, on the contrary mostly be suspectable people with the people that hand is taken off lid.The record so should make a video recording, and be the important preceding shooting of case record.

Two, based on above-mentioned situation, record three kinds of functions before the case of measure of the present invention, one of function be that shooting begins immediately as long as hand touches lockhole top cover plate, if stop to continue, stop shooting automatically.Two be when automatic camera records, to have recorded simultaneously the time of taking place at that time, three be occurrence record after, the Presentation Function of record before the case will be arranged, the overwriting situation once took place in the people in the family of announcement, to watch.

Three, can preset with the rule of time period and initiatively make a video recording, namely be artificially on one's own initiative with time set on a certain period, this moment, video camera recorded ambient conditions with automatic camera, rather than will contact the lockhole cover plate.This situation mainly is for the active monitoring of the people of family to environment.It should be noted that it is whole shootings of 24 hours all day that this period comprises.

Four, the shooting of the overall process after crime is produced.

Five, produce the principle explanation of above function: (explain with Fig. 1.）

Produce the principle of contact lockhole cap automatic camera record: cover sheet when the hand contact is locked into lockhole, after being hole top cover plate (among Fig. 1 101), the touch signal that has taken out human body enters the polystage amplifier amplification that not gate forms (among Fig. 1 105, to 108 etc.) by emitter follower (among Fig. 1 102) input then, enter at last or door (among Fig. 1 111) input, enter electronic switch (among Fig. 1 112) at last, open video camera work (among Fig. 1 113) at last.If stop to continue, no touch signal then, so electronic switch is not open-minded, the camera system non-transformer is not worked.

Producing the principle of period shooting record: 116 among Fig. 1 is a kind of have time control and instruments (abbreviation time-controlling apparatus) that show, as long as preestablished the time, it will output signal, through or door (among Fig. 1 111) after, open electronic switch (among Fig. 1 112), allow video camera work then.

Produce the principle of shooting record overall process: although the back hand of forcing open the door has left lockhole top cover plate, but above the lockhole and the alarm switch contact that is pressed under the cover plate is not oppressed by cover plate, variation has taken place, and switch 119 is closed among this Fig. 1, so opened the video camera job record.

Behind the shooting record displaying principle is arranged before the generation case: 118 is a kind of rest-set flip-flops with demonstration among Fig. 1, thereby have Memorability, when each or door has output to open electronic switch 112, all can trigger the rest-set flip-flop of memory, in case so after rest-set flip-flop was triggered, additional LEDs can luminous demonstration.

The principle of shooting record writing time before the generation case: when each or door had output to open electronic switch 112, signal triggering has been arranged time controller was so can record the moment of generation automatically.

Six, produce the warning function principle: when door and doorframe are subjected to displacement, the travel switch contact of pacifying every and doorframe junction changes, and has produced the warning enabling signal; When loosening or open the cover plate of lockhole top fully after, the lockhole shift knob of being satisfied with cover plate below, lockhole top does not suffer oppression and the contact changes, also produce the warning enabling signal, the contact of biswitch starts video camera work, has opened warning system work simultaneously.

Seven, the such installation benefit of warning starting switch be sensitive, reliable, can generation not make us terrified wrong report simultaneously.Reason one is alarm switch when event does not take place, and the contact can not be subjected to displacement.The 2nd, do not influence the normal habits and customs of people, thereby do not influence the operate as normal of the each starting of security system.

Eight, the electronics latching circuit has played vital role in the present invention, its main effect has 2 points: 1, relaxed the requirement to switch, be that switch can be by of bonding, it also can be button-type, and the power of contact there is not influence, so can adopt miniaturely, to reduce the switch mounting hardness, increase the attractive in appearance of door simultaneously.

2, sensitivity and the reliability of the starting of reporting to the police have been improved.Its reason one is, because principle of the present invention is, and when its people has the action that cracks lockhole, (referring to unclamp the behavior of the screw on the lockhole upper cover plate), and switch has produced displacement, and latching circuit starts immediately, and irretrievable, will send initiating signal.

Nine, power supply is an emphasis of the present invention, and the spy makes the following instructions circuit:

1, the reason that has good anti-thunderbolt effect: when thunderbolt is arranged, usually being power supply perishable the time, is that take the to cut off the power supply mode in source is avoided as common household electrical appliances, because these class household electrical appliances are made interim power down process, can not produce serious consequence.But as the specialities of security personnel's class, it is blank to become security personnel as resolute power down source, is first emphasis of the present invention so improve lightning protection effect.

The first, overvoltage voltage-limiting protection Unit second and overvoltage fast tripping protection first module have been formed " fast tripping protection function ", and excellent performance has very strong lightning protection overvoltage capabilities.

(1), the principle of Xing Chenging is: if thunderbolt and when causing output terminal too high and after surpassing the door of diac 6; silicon controlled triggers 6 conductings of element stabilivolt; thereby triggering controllable silicon 4 conductings; immediately to the base stage short circuit of the triode 5 in the overvoltage voltage-limiting protection first module; make this manage complete no-output; three end integrated circuit input no-voltage forms lightning protection overvoltage fast tripping protection.

(2), why be called " fast tripping protection function ", in case be because output terminal when too high, the controllable silicon conducting has very strong positive feedback, can will adjust the base stage short circuit of pipe rapidly, protection whole process is both very rapid, and protection thoroughly.Realize sealing up a door fully.

(3), the automatic restorability of protection controllable silicon is good.Reason is after producing protection, triode 5 no-outputs in the first module, and triggerless voltage, the controllable silicon anode has resistance in addition; to lose the self-sustaining electric current automatically, revert to open-circuit condition voluntarily, if be struck by lightning again; starting again, form protection, is normal value until output voltage.

(4), the controllable silicon that shields and peripherally trigger " the fast tripping protection function " that part forms and when work, be in " open-circuit condition ", as long as just work when thunderbolt or overvoltage, so be not easy to damage, all be in a kind of guard mode constantly.

Its reason is power output end when being normal condition, and controllable silicon is in off state, does not have " electrical wear ", can not damage.Its external trigger is enclosed part stabilivolt voltage stabilizing value and is higher than output end voltage, so also be in open-circuit condition, does not have " electrical wear ", also can not damage, and all can be at any time a kind of " armed state ".

The second, overvoltage voltage-limiting protection first module has formed the secondary voltage-limiting protection function of anti-lightning strike protection to thunderbolt, further perfect protection to integrated circuit.

Its reason is, the base stage of triode 5 has voltage stabilizing diode over the ground, therefore should pipe output by clamper, pressure limiting has been carried out in shoving that this diode pair thunderbolt produces, and is further replenishing with perfect " fast tripping protection ".

2, the reason one that can not damage circuit in the higher place of civil power and period is that civil power can not be higher than thunderbolt when high and gushes pressure, the 2nd, and triode 5 is that high inverse-voltage tube has very strong back-pressure value.

3, can be in the main cause of the lower place of civil power and period work: because preposition triode is high inverse-voltage tube, so when design, can design the bridge-type output voltage higherly, when civil power was low, at this moment bridge-type voltage can not be very low, just can do certain compensation.

4, can adjust the reason of different output voltage stabilizing values.Owing to increased peripheral element adjustable resistance 9 and 10 in the measure, thereby can be on reference voltage, realize that again output voltage adjusts flexibly, with the realization 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, after the invention process, anti-theft safety door and alarm have been realized the combination of science, three kinds of function collection are one, one of be to have the function that the people is kept outside the door, two are the functions with automatic camera record, three are the functions of reporting to the police, three kinds of functions are all very important, promote security personnel's performance of anti-theft safety door all sidedly, enriched the kind of antitheft door.

2, shooting record performance excellence.The one, record is given prominence to the key points before the case.The 2nd, after being arranged, record can show the owner of announcement automatically, can " not leak visit ".The 3rd, cases has taken place to do can record overall process.The 4th, shooting records various ways.The 5th, at record time of generation is arranged the time.These 5 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, have realized that really workable characteristics are.(in the situation of work strain, family can not carry out " return visit " to shooting by impunity, more impossible in return visit, watch a lot of useless impunities general records).Thereby for understanding the family public security present situation, very important positive role is arranged.

3, warning function is reliable and sensitive, does not importantly produce wrong report.

4, reliable, easy to use.Reason one be video camera recorder and warning system at ordinary times most cases be in the no power state, do not produce electrical wear, at any time all be in a kind of " highly waiting " state, the 2nd, closing the door when opening without any need for other additional move user between the whole operating period, do not influence normal habits and customs, can not produce malfunctioning situation.

5, the amplifying circuit of shooting record automatic control unit is outstanding before the case, has guaranteed the reliable and sensitive of core circuit.Reason one is that emitter follower can realize that the coupling between lockhole cover plate and the amplifier takes out signal reliably after as impact damper well.The 2nd, the sensitivity at different levels of amplifier is adjustable flexibly, and very high amplification coefficient is arranged.The 3rd, functional level has good shaping operation, realized the digitizing output conversion of (0) with (1) of standard, thereby resolving power is very strong; It is big to export energy simultaneously, and there is very strong triggering ability in subordinate.

6, produce easily, the one, the simple and reliable debugging of circuit is easy, and the 2nd, do not need the instrument and meter of price top grade.

7, the requirement to switch is relaxed in the utilization of electronics latching circuit, improves sensitivity and the reliability of reporting to the police and starting.

8, the benefit of hybrid power supply have following some: (1), anti-thunder and overvoltage protection effect are fine.So at thunderstorm season, needn't make power down process, institute's adapted equipment can be because thundery sky quit work, if be used on security personnel's equipment, guaranteed that " security personnel " do not produce blank, and be difficult to reach this effect with three traditional end integrated circuit and uniting of triode.

(2), this line thunder protection effect is more much better than anti-thunder tube commonly used.Its reason one is that lightning protection function is and back level quick-break rather than shorted to earth, and prime is not had negative role.The 2nd, the model of the anti-thunder tube that " suctioning through voltage " is low is difficult for having bought, and the model scope of diac of the present invention 6 is extremely wide, is easy to required " suctioning through " magnitude of voltage of supporting one-tenth, suctions through 30 volts of following protections of voltage so be easy to supporting one-tenth.The 3rd, the present invention has " quick-break " and pressure limiting duplicate protection, thereby effective.

(3), adapt to widely, than traditional stabilized voltage supply wideer adaptive faculty is arranged, at the voltage height that meets accident, can not damage.And also can operate as normal in voltage lower place and period.

(4), available adjustment output the generation has the voltage stabilizing value of decimal, be convenient to the floating charge of accumulator science.Has overcurrent protection simultaneously.Be fruitful or other electronic products have excellent performance after supporting.

(5), the voltage regulation performance excellence because it has all advantages of three end integrated regulated power supplies.

(6), easily produce.Reason one is to have adopted complex function, the simple in circuits compactness; The 2nd, because the debug point in the circuit is few.The 3rd, the very easy quantification of debug point, the debugging scope is loose.

(7), cheap, cheap more a lot of than a lot of satisfactory a lot of stabilized voltage supplys.
