For having a clear understanding of the meaning of the technical program, first make the following instructions:
1, before this, 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, by remote control, to the propulsion system that are installed in door, send instruction, promote lockset action, realization is opened 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 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 the security personnel of ，Dui 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 great majority crime is all by cracking of lockhole entered house.For this reason, 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 the time occurring at that time simultaneously, three be occurrence record after, will have the Presentation Function recording before case, announcements in people once there is overwriting situation, to watch.
4, can preset with the rule of time period and initiatively make a video recording, be 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 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 to the overall process after crime generation.
Further explain:
One, produce the principle explanation of shooting-recording function: (with Fig. 1, explain.）
Produce the principle of contact lockhole cap automatic camera record: when criminal's hand touches after 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 sensitivity and the reliability of pre-alarm 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 hand has left lockhole top cover plate after forcing open the door, but above lockhole and the alarm switch contact being pressed under cover plate is not oppressed by cover plate, variation has occurred, and in this Fig. 1, switch 119 is closed, so opened video camera job record.
Before generation case, after shooting record, there is displaying principle: in Fig. 1,118 is a kind of rest-set flip-flops with demonstration, thereby there is Memorability, when each or door has output to open electronic switch 112, all can trigger the rest-set flip-flop of memory, once so after rest-set flip-flop is triggered, additional LED can luminescence display.
The principle of shooting record writing time before generation case: when each or door has output to open electronic switch 112, have signal to trigger time controller, so can automatically record the moment of generation.
Produce 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 warning enabling signal, when becoming flexible or opening completely after the coverage sheet of lockhole top, the lockhole shift knob of being satisfied with cover plate below, lockhole top does not suffer oppression and contact changes, also produce warning enabling signal, when on off state changes, signal has been sent to first triode NPN base stage in timing feedback, now current collection is very low, second transistor collector is high, output signal, meanwhile, the positive feedback branch forming 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, all the time there is signal output, arrived after certain hour, feedback branch Capacitance derivative is full of electricity, feedback branch lost efficacy, so positive feedback is regularly, not eternal.
For timing feedback circuit also should illustrate following some:
So 1 will add positive feedback branch, there are 3 meanings, (1), relaxed the requirement to switch, be that switch can be key type, also can be 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, the action of lockhole protection switch, sends warning initiating signal, starts immediately radio remote-controlled circuit starting, allows telephone set within doors receive and produces telephone alarm function.If therefore have people cracking lockhole, (referring to the behavior of unclamping the screw on 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 multi-code transmitter circuit, when transmitting, needs the regular hour, if without this circuit, in some cases, does not just likely guarantee the so long time.And had this circuit, just can guarantee that the transmitting of starting is each time all very reliable.Reason three is that 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, has had after feedback branch, and 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 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, be 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, debugging surplus is larger, and choose with electrodeless electric capacity, be that 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 to become electrodeless method with electrochemical capacitor, in figure, choose the method for having used the negative pole of two electrochemical capacitors to be connected together, adopt after this method, capacitance can conveniently combine, and leakage coefficient can improve a lot of a lot, in this programme because of there being positive feedback circuit, 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.
6, used wireless remote control transmitting, there is important meaning, if remote control be subject to weather and surrounding environment influence large, if can not notify in time personnel outside when there is something special, that is very serious, description of test, the distance of radio controlled transmitting has much relations with size when same circuit.Because it has a great impact with reliability the stable of radio ttransmitter and receiver.Therefore copper foil antenna has been made English lower case n shape, antenna Copper Foil width is 2mm, and left and right is the Copper Foil of two vertical parallel shapes, and Copper Foil length is 30mm, article two, 20 mm of the distance between the Copper Foil of vertical parallel shape, connect with arc Copper Foil kiss above the Copper Foil of two vertical parallel shapes.Allow transmitting with receive between can realize well and mating, guarantee the accurate of signal transmission.
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 while there is not event, 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.
Four, in signal conditioning package, have two kinds of electronic circuits, a kind of is radio reception circuit, and the wireless remote control that its energy reliable reception sends from user transmits; Another kind is to receive programme control circut, connects the extension line from telephone key rosette copper paper tinsel, allows the number of storing in telephone set transfer to successively.
Dialing integrated circuit in telephone set has following function, the one, can store a plurality of telephone numbers, in the situation that prior oneself storage is complete (the present invention can utilize former existing phone to store this integrated circuit), as long as being stored to pin, it adds a trigger pip, this sheet will automatically be controlled and send a phone number dial, so being connected on respectively, its a plurality of storage number ends receive on a plurality of output terminals in programme control circut, the dialing output terminal of this integrated circuit has been connected on telephone set, so when starting telephone call, the multi-section telephone number that a plurality of output terminals of reception 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 phone circular function is very powerful.
After the invention process, anti-theft security goalkeeper presents a kind of brand-new looks, has following outstanding advantage:
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 there is the function that 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, is all applicable to all-environment needs, and circuit is simple, and debugging is convenient.
3, shooting record performance is excellent.The one, before case, record is given prominence to the key points.The 2nd, after having record, can automatically show the owner of announcement, can " not leak visit ".The 3rd, there is to do cases and can record overall process.The 4th, shooting records various ways.The 5th, when recording, there is time of generation.These 5 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, have really realized workable feature and have been.(in the situation of work strain, family can not impunity carry out " returns visit " to shooting, more impossible in return visit, watch a lot of useless impunities general to record).Thereby for understanding family public security present situation, there is very important positive role.
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 in no power state, do not produce electrical wear, at any time all in 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, relaxed the installation requirement for warning starting switch, reporting to the police, it is more accurate to start.
9, transmitting has obtained better coupling with reception, reports to the police more credible reliable.
10, advanced in performance, owing to utilizing network platform transmission of information, hurry up, and with people place range-independence, report great efforts, can store multi-section phone, send out mass-sending, such benefit is to carry out Advise By Wire to a plurality of personnel simultaneously, and telephone set can be as warning device when there is something special, general time, it is exactly common communication telephones.
