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.
6, produce the principle explanation of above 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.
7, 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 contact changes, also produce the warning enabling signal, the contact of biswitch has connected electronic self-locking circuit, the output of electronic self-locking circuit starts video camera work, has opened simultaneously warning system work.
One of the principle of electronic self-locking circuit is: the form to the pipe amplification that (1) adopts NPN and PNP to constitute jointly, following meaning is arranged,, amplification quantity is large; Two, the PNP triode become saturated after, the loss of voltage of generation little (when being furnished with accumulator, peculiar meaning); Three, can easily transient signal be changed into to a kind of long signal; Four, formed electronic switch volume urine is in miniaturization.
(2), in the electronic switching circuit that pipe is formed, anti-remaining resistance, namely that the resistance connect between PNP transistor emitter and base stage has played vital role in circuit, its effect is when NPN triode no signal, the thorough no-voltage of the output of switch, output, without any remaining electricity, for the through engineering approaches that electronic switch uses, has been created essential condition.
(3), why between two pipes, add the positive feedback with Capacitance derivative, the one, meet this condition, the 2nd, can realize automatic recovery.
(4), why feedback capacity adopts electrodeless reason to be, the electrodeless electric capacity leakage coefficient is little, under at feedback circuit, circuit is more stable.
8, 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.
9, in technical scheme 1, implemented the wireless remote control emission and adopted the multi-code transmitter scheme, important meaning is arranged, main benefit is to be difficult for producing malfunction.Structure of the present invention is that the warning starting switch is the lockhole protection switch, and when cracking lockhole, switch contact is subjected to displacement, and sends the command of execution of having reported to the police, and Telephone set just starts telephone call within doors.Owing to producing telephone call, be a very serious thing, if wrong report, unnecessary terrified by causing, consequence is very serious.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 interferences that just can thoroughly stop afterwards this class., after otherwise the multi-code transmitter circuit has been arranged, must be non-normal door if alarm call is arranged, so have greatly improved the confidence level that the present invention reports to the police.This circuit realizes that its principle of multi-code transmitter is; When the first end output of programme control circut was high-order, it was low that the phase 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 modulator tube, so form the form of multi-code transmitter.
10, the principle of sound system is: be comprised of a triode prestage that sound equipment amplifies, by a PNP and NPN triode, formed complementary circuit audio frequency has been carried out to power amplifier, when pre-caution signal is arranged, the power supply of having opened this part is controlled in its output, so have voice to produce, due to this electric circuit constitute be an OTL rather than OCL circuit, so debugging is simple, and have element not perishable, and the higher advantage of efficiency.
11, two kinds of electronic circuits are arranged in signal conditioning package, 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 is to receive programme control circut, connects the extension line from telephone key rosette copper paper tinsel, allows in telephone set the number of storing transfer to successively.
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.
