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

1, before this, the inventor is studied 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, to the propulsion system that are installed in door, send instruction by remote control, promote the lockset action, realize opening the door.Meanwhile, still retained the form that mechanical key opens the door, its objective is and when automatic system goes wrong, can have a kind of opening the door to make up, so antitheft door can be made lockhole semiclosed processing, its meaning is, during normal the use, lockhole is covered, and only during out of order special circumstances, just lockhole is covered to sheet and is opened.

2, 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 is all 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 with the people that hand is taken off lid, be mostly suspectable people.The record so should make a video recording, and be the important front shooting of case record.

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

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

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

Further explain:

One, produce the principle explanation of shooting-recording function: (explain with Fig. 1.）

Produce the principle of contact lockhole cap automatic camera record: after criminal's hand touches the signal leading sheet of lockhole top, just be imported in the in-phase end of operational amplifier of the first order and amplify, being input to again afterwards comparison amplifier further amplifies, this have a very large gain, can fully guarantee to warn in advance sensitivity and the reliability of signal.Its reason is in this circuit, the resistance of first order operation amplifier level (in Fig. 1 103) can be adjusted the gain of this grade flexibly, and the divider resistance ratio (106 in accompanying drawing 1) of adjusting the comparison amplifier end of oppisite phase that second level operation amplifier level forms can be adjusted again the gain of this grade flexibly.

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

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

Before the generation case, after the shooting record, displaying principle is arranged: in Fig. 1,118 is a kind of rest-set flip-flops with demonstration, 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 LED can luminescence display.

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

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 coverage sheet of lockhole top fully after, the lockhole shift knob of being satisfied with cover plate below, lockhole top does not suffer oppression and contact changes, also produce the warning enabling signal, when on off state changes, signal has been sent to first triode NPN base stage in the timing feedback, now current collection is very low, second transistor collector is high, output signal, meanwhile, the positive feedback branch formed 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 the timing feedback circuit also should illustrate following some:

So 1 will add positive feedback branch, 3 meanings are arranged, (1), relaxed the 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, increase 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 had the action that cracks lockhole, the action of lockhole protection switch, sent the warning initiating signal, starts immediately the radio remote-controlled circuit starting, allows within doors telephone set receive and produces telephone alarm function.If therefore have the people cracking lockhole, (referring to the behavior of unclamping the screw on the lockhole upper cover plate), switch has produced displacement, and latching circuit starts immediately, and irretrievable, will send initiating signal.Reason two is that owing to being security personnel's products, its wireless remote control 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.Reason three is that the inventor is applied to the series products of ensuring public security, non-one of radio coding integrated circuit, but polylith, and this is more much longer than the simple radiating circuit time, and after feedback branch had been arranged, that is operation of short duration I guess, can guarantee to launch required time at every turn.Reason four is strengthening amplification quantity, has improved the reliability of controlling the wireless remote control radiating circuit.

2, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and now the second pipe collector is high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe, to the charging of feedback capacity differential, is fed back, 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 meet the necessary preparation of feedback next time.

3, feedback capacity is micro-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, and choose with electrodeless electric capacity, be that the electric leakage system is little, feedback branch is more stable, if but with selecting electrodeless electric capacity capacious, sometimes be difficult for looking for, and price is higher, so proposed, become electrodeless method with electrochemical capacitor, in figure, choose the method that the negative pole of having used two electrochemical capacitors is connected together, after adopting this method, capacitance can conveniently combine, and leakage coefficient can improve a lot of a lot, in this programme because of 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.

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

Three, sound system has used integrated amplifier 386, and element is few, and amplification effect is good, and audio is good.

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 functions integrate, 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 all sidedly security personnel's performance of anti-theft safety door, enriched the kind of antitheft door.

2, shooting with video-corder operation circuit has very high sensitivity and reliability, after debugging, all is applicable to all-environment needs, and circuit is simple, and debugging is convenient.

3, shooting record performance excellence.The one, before case, record is given prominence to the key points.The 2nd, after being arranged, record can automatically show the owner of announcement, can " not leak visit ".The 3rd, cases has occurred to do can record overall process.The 4th, shooting records various ways.The 5th, time of generation is arranged when recording.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.

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

5, 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, all be at any time a kind of " highly waiting " state, the 2nd, user between the whole operating period, closing the door when opening without any need for other additional move, do not affect normal habits and customs, can not produce malfunctioning situation.

6, produce easily, do not need the instrument and meter of price top grade.

7, the line power of sound equipment caution system is large, simple, and debugging is convenient, power saving.

8, the warning startup is more accurate, and the installation requirement of warning starting switch has been lowerd.
