In order to the meaning of each technical measures of clear interpretation, be first explained as follows:

Inventor studies anti-theft technique for many years, existing achievement is that normal door is without mechanical key, but by the mode that electronics telecontrol engineering or phone open the door, under normal circumstances, the propulsion system be installed in door promote lockset and realize opening the door, but also retains traditional door-opening mode of mechanical key, its objective is when electronic technology goes wrong, can also open the door and enter house, as a kind of compensating mode of enabling, but lockhole is cover in the ordinary course of things, if will be opened the door by lockhole, onsite alarming device and telephone alarm all can start warning, possesses recognition function, if the open alarm gone wrong because of electronic technology, one of own side is had to exist, there will not be fear, otherwise, lockhole when electronic technology does not go wrong opens the door, it must be crime behavior, because crime behavior does not input correct electronic signal, warning and photorecorder will be started.

A kind of guarding door of self-monitoring band video recorder; namely be just produce to warn prevention in advance at the beginning of crime; carry out record before case simultaneously; because at the beginning of now still committing a crime; formally warning can also be started what fail to prevent; and the whole process of committing a crime under offical record; cooperation is monitor; again protector simultaneously; can also the power supply of voltage stabilizing; make alarm whether damagedly need not detect as cases by simulation, make alarm under any circumstance can ensure the serviceability that equipment is excellent, improve security personnel's performance of anti-theft safety door all sidedly.

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

One, reason and the principle thereof of pre-warning is produced.

Because lockhole is covered on anti-theft safety door, and theft is under normal circumstances all by lockhole for it, therefore when hand has just contacted lockhole cover plate, touch signal will be produced, this signal is after warning start-up circuit takes out amplification, direct triggers presence alarm sends warning and prevents, and record before carrying out case.

1, the extension line of lockhole cover plate connects the low valve valve end of preposition oscillator after commissure electric capacity, therefore, when hand contact lockhole cover plate produces touch signal, this signal enters oscillatory circuit inside, produce accurate vibration, cause vibration failure of oscillation or seriously change, making the output of the OUT pin of oscillatory circuit and oscillatory circuit (07 in Fig. 3) have high-order output.This high-order output becomes the power supply of onsite alarming device after amplifying circuit, form on-the-spot warning to prevent, warning now, also just perpetrator has the incipient stage of crime behavior, therefore be pre-warning, and now trigger the record of shooting with video-corder circuit and being formed, because also at the beginning of crime, therefore be record before case, record the motivation of crime.

In warning start-up circuit, oscillatory circuit is reliable, touch-sensitive, and its reason is that oscillatory circuit is not when there being touch signal, oscillatory circuit is in vibrational stabilization state, and after having touch signal, great change inherently occurs oscillating operation condition, output terminal must have high-order output.The ground capacitance of output end of oscillating circuit has interference effect, improves this grade of performance from another angle.Oscillatory circuit is structurally being combined into of mimic channel and digital circuit, analog functuion and logic function compatibility is integrated, and produces and vibrates accurately, a power supply can be shared with amplifying circuit, and oscillatory circuit maximum output current 200mA, carrying load ability is strong, use reliable, the life-span is long.

2, amplifying circuit is formed by two inverter series, strengthen shaping and amplifying power, because phase inverter quiescent dissipation is extremely low, during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, reducing time delay, so when there being signal, exporting reliable in time.The sensitivity of phase inverter adjusts very well, and a sensitivity adjustment resistance joined by each phase inverter, and its sensitivity resistor resistance is large, sensitivity step-down, and resistance is little, and sensitivity raises, and has very strong adjustable.

As long as thus there is crime behavior, just reliably have issued while hand has just contacted lockhole cover plate and warn prevention in advance, form psychological pressure to perpetrator, make it to understand that house owner early has preparation, avoid to a great extent continuing stolen possibility.

Two, power supply is the basis of all electronic equipments, is also an emphasis, and thus spy is described power supply.

Realization can voltage stabilizing; can monitoring and protecting be formed again, while the series of advantages ensureing three-terminal voltage-stabilizing, implement fast tripping protection at the two ends of three terminal regulator; when there being fault; fast tripping protection can be started in time, initiatively the prompting of formation sound and light, reduce the failure rate that power supply produces; formation is monitor; simultaneously again protector, can also the power supply of voltage stabilizing, be an emphasis in this measure.

(1), input end overvoltage forms the principle of monitoring and fast tripping protection.

At the output terminal of bridge rectifier, be alternatively that the input end of three-terminal voltage-stabilizing circuit has input end observation circuit, for the voltage condition of monitor input terminal.

1, meaning: the protection that this circuit has unexpected situation to be formed mainly for the external world, as thunderbolt, or the rising that the outer circuit of civil power surprisingly causes.Although there is lightning arrester product market now, suctions through the product of voltage below 100 volts and be difficult to buy, let alone be the product of less than 36 volts.

2, principle: gush pressure when rectification exports to have by thunderbolt, or when having overvoltage under fortuitous event, input end observation circuit starts immediately, opens complementary circuit, clamper controllable silicon quick-break circuit, powered-down, formation fast tripping protection.

Exceed the voltage stabilizing value of input end overvoltage door stabilivolt (905 in Fig. 2) at the voltage of rectification output end after, input end monitoring pilot lamp (906 in Fig. 2) sends light, NPN triode (910 in Fig. 2) in trigger complementary circuit, because complementary circuit is designed with Derivative Feedback unit, thus response is exceedingly fast, make NPN triode (910 in Fig. 2) current collection very snowslide step-down, PNP triode (913 in Fig. 2) is saturated rapidly, its collector produces high pressure, the control pole of the quick-break controllable silicon (908 in Fig. 2) in clamp diode (912 in Fig. 2) clamper controllable silicon quick-break circuit, thus make quick-break silicon controlled negative electrode Non voltage output, powered-down, produce quick-break and thus form protection.

Because PNP triode (913 in Fig. 2) becomes in saturated process from cut-off, this pipe collector has electricity, so drive acoustical generator (918 in Fig. 2) sounding.

3, line feature: A, because starting resistance one (907 in Fig. 2) resistance of quick-break controllable silicon (908 in Fig. 2) is very large, all can trigger when hundreds of K, as long as so debugged the resistance of protective resistance one, just can cause starting triode saturated or to saturated change, due to quick-break silicon controlled positive feedback, so quick-break controllable silicon can towards the change of cut-off direction, (it should be noted that here, textbook is said, controllable silicon cut-off condition is when anode current reduces and is less than when maintaining electric current and can changes to cut-off direction, but concerning one-way SCR, theory and practice all illustrates, silicon controlled negative electrode is reduced to zero, controllable silicon still can be made towards the change of cut-off direction.) and controllable silicon also has strong positive feedback, therefore, coordinates with complementary circuit, can form the protection of quick-break.

B, owing to there being strong positive feedback in complementary circuit, so protection is for avalanche type, its effect one is that response is exceedingly fast, and two is that PNP triode current collection can arrive rapidly a high position, so can make quick-break silicon controlled negative electrode Non voltage output.

The feedback being fed back to derivative-type electric capacity in complementary circuit, so there is following advantage: one is when thunderbolt or overvoltage terminate, and can automatically recover, because the differential capacitance (914 in Fig. 2) of feedback has timeliness.Two is if thunderbolt or overvoltage are continuous print is transient state, but because there is positive feedback, so the time will carry out time delay, further reduces impact risk.Three is because feedback branch has two time constants of charge and discharge, and within these two times are normal, PNP controls triode and is in conducting state, so now acoustical generator responds, can not produce the inefficacy of monitoring instruction because the overvoltage time is too short.

C, voltage stabilizing value due to input end overvoltage door stabilivolt, can find easily, so threshold value height meter flexibly, also can implement very easily.

Because PNP triode has high-order output, so the warning of sound is very reliable when overturning.

(2), output terminal overvoltage forms monitoring and the principle explanation protected.

1, meaning: this protection mainly checks the one protection produced after three-terminal voltage-stabilizing inside circuit damages; if three-terminal voltage-stabilizing circuit damages; its voltage stabilizing value exported generally can raise; then load is produced to the serious harm of overvoltage; owing to being the keypoint part of power supply usually fault infringement, so be necessary carrying out separately monitor and protecting.

2, the principle formed: after output voltage raises, the threshold voltage of adjustable door circuit is broken through, and output terminal monitoring pilot lamp (925 in Fig. 2) is now shinny.Start complementary circuit clamper quick-break silicon controlled and control pole, rapid powered-down and form protection, warning of simultaneously sounding.

The door of 3, line feature analysis: A, this point protection adopts continuously adjustable triode mimic channel, so protective adaptation face is very wide.

For 78 series, three end integrated stable voltage circuit voltage stabilizing values are different, as voltage stabilizing value has 5 volts respectively, and 6 volts, 8 volts 12 volts, so the standard of overvoltage is different.And the voltage stabilizing diode of correspondence is bad coordinates therewith.Because the threshold value of three end integrated stable voltage circuit output terminal protection branch roads have employed continuously adjustable triode mimic channel; the threshold value of the voltage stabilizing diode of its simulation is selected flexibly and continuously adjustabe; thus the standard of design protection can be formulated flexibly; can not be restricted, so all three end integrated stable voltage circuits can be adapted to.The principle formed is; after on the adjustable door of adjustable triode (921 in Fig. 2), inclined resistance (920 in Fig. 2) resistance increases; on this resistance, dividing potential drop increases; the dividing potential drop of base stage and emitter reduces; also because complementary circuit and quick-break controllable silicon have the positive feedback arranged by force, so protection is avalanche type.

(3), input end monitoring pilot lamp and output terminal monitor the luminotron of the different colours that pilot lamp is, therefore judges it is that front end or rear end there occurs fault very well, applicable and reliably.

Three, the effect of alarm switch: be arranged on above door lock hole, the alarm switch below lockhole cover plate is an emphasis, fails in the crime behavior of prevention in pre-warning, and it starts the key of reporting to the police.

Pre-warning fail prevent crime behavior, if continue to crack lockhole, when lockhole cover plate souththern pine moves, the button of alarm switch no longer makes contact change by the compressing of lockhole cover plate, thus produce warning enabling signal, while excitation onsite alarming device, start radio transmitter circuit and send tele-alarm signal, and circuit is shot with video-corder in triggering, form shooting record.

Alarm switch has allowed warning accomplish more scientific after matching with the existing achievement of inventor, and its reason is:

1, can not produce and make us terrified wrong report, this is the most important.Its reason is, the enabling (opening with improper door) that is absent from the scene of owner within doors, are all crime behaviors, warning is now very crucial.

2, very reliable because normal life enabling at closing time, do not need artificial additional move, do not affect the normal habits and customs of people, thus do not affect the normal work that security system is started at every turn.

3, the starting of alarm switch is sensitive and reliable, just can report to the police, thus loss is reduced to minimum when crime behavior is not accomplished.Warning initiating signal is produced because lockhole cover plate will change at loosening alarm switch contact.

Four, on-the-spot alarming effect is remarkable, simultaneously with shooting record, is convenient to understand course of event afterwards, very beneficial to solving a case.

Shoot with video-corder circuit by starting or door, electronic switch, photorecorder, forming with the rest-set flip-flop of display, time controller, manual control switch.

The output of warning start-up circuit, another contact extension line of alarm switch, a contact extension line of manual control switch, time controller receive the input starting OR circuit respectively, as long as or the characteristic of door has an input end to meet condition, so just have output, therefore be no matter that warning start-up circuit in pre-warning has output, or alarm switch contact there occurs change, or manual control switch contact changes, all can start photorecorder, form shooting record.

1, time controller (27 in Fig. 4) is the instrument with time controling and display, as long as preset the time, it will output signal, after startup or door (20 in Fig. 4), open electronic switch (in Fig. 4 24), then allow photorecorder (25 in Fig. 4) work, and start onsite alarming circuit.

2, the principle of shooting record overall process is produced: although hand have left the lockhole cover plate above lockhole after forcing open the door, but the alarm switch button under being pressed in theft protection plate is no longer by the compressing of lockhole cover plate, there occurs change, alarm switch (3 in Fig. 4) is closed, so opened photorecorder job record.

3, displaying principle is had after shooting record before generation case: in Fig. 4,26 is a kind of rest-set flip-flops with display, thus there is Memorability, each or door has output to open electronic switch (in Fig. 4 24) time, the rest-set flip-flop having display is triggered in capital, so once after rest-set flip-flop is triggered, additional LED can luminescence display.

4, the principle of shooting record writing time before generation case: at every turn shoot with video-corder control or door when having output to open electronic switch, signal is had to trigger time controller, so automatically can record the moment of generation, thus each hand contact lockhole cover plate all can produce and shoot with video-corder and onsite alarming.

Five, radio transmitter circuit has used brand-new technology, after radio transmitter circuit energising, annular oscillation circuit starts rapidly, because the change code of coding integrated circuit has terminated in the output of annular oscillation circuit, therefore, coding integrated circuit is no longer fixing code, thus improves safety coefficient, stop the interference of the various electrical equipment of social upper existence, made signal transmission more accurate.

And the power supply of radio transmitter circuit is provided by alarm switch, a contact extension line of alarm switch connects with the power end of warning start-up circuit, another contact extension line connects three tunnels, one tunnel connects the first isolating diode positive pole of onsite alarming device, the negative pole of the first isolating diode of onsite alarming device connects the power end of onsite alarming device, second tunnel connects the positive pole of the isolating diode of radio transmitter circuit, the negative pole of the isolating diode of radio transmitter circuit connects radio transmitter circuit power supply, 3rd tunnel connects another input end of shooting with video-corder startup or door in circuit, so when lockhole cover plate loosens, the contact of alarm switch changes, radio transmitter circuit is energized immediately.

1, better implement to allow measure, deviser aims at this line design one and forms a kind of annular oscillation circuit by gate circuit, the principle of its vibration is: in power on circuitry in a flash, the input end of first gate circuit (40 in Fig. 6) is high-order, because differential capacitance (42 in Fig. 6) can not the reason of transition in transition, a high position will be delivered to rapidly the input end of second gate circuit (43 in Fig. 6), thus make the output terminal of second gate circuit (43 in Fig. 6) for high, the output terminal of the 3rd gate circuit (44 in Fig. 6) is low, thus the input end of first gate circuit (40 in Fig. 6) continues as low and keeps a period of time, within this time, the output terminal of the 3rd gate circuit (44 in Fig. 6) is charged through the output terminal of adjustable resistance (41 in Fig. 6) to first gate circuit (40 in Fig. 6) by differential capacitance (42 in Fig. 6) again, (because this gate output is low level), after differential capacitance charging, electric capacity becomes off-position, second gate circuit input end becomes low level from a high position, at this moment the state between each gate circuit takes a turn for the worse, state is now that second gate output is for high-order, 3rd gate output is low level, first gate output is high-order, also because differential capacitance can not the principle of transition, this state will keep a period of time, the physical process of this period is that the output terminal of first gate circuit can be crossed adjustable resistance and carry out reciprocal charging to differential capacitance, form the later half cycle of vibration.Principle like this carries out the second time cycle, and the later cycle.

In foregoing circuit, in order to make vibration starting of oscillation easy, make vibrational stabilization reliable, deviser has done following adjustment change, one is be designed to electrodeless by the differential capacitance in circuit, decrease the electric leakage composition of electric capacity, improve Q value, two is add adjustable composition to the time constant of vibration to be beneficial to adjustment.Test shows that this circuit and overall circuit are worked good, and has very strong exploitativeness.

2, in measure 1, annular oscillation circuit defines such annexation with coding integrated circuit, the coded portion of coding integrated circuit has been divided into two parts, a part is the fixed code connected in advance, this fixed code can ground connection, also can connect power supply, flexible and changeable, another part is the change code be connected with annular oscillation circuit.When manual operation transmitting or alarm switch contact change, annular oscillation circuit vibrates, and the change code end of coding integrated circuit just becomes two states, and integrated circuit of at this moment encoding just can only become dicode two kinds output by a kind of single code transmissions from former.By the excitation to modulator tube, reach the object of dicode modulate emission.

Six, have two kinds of electronic circuits in telephone alarm, one is radio receiver circuit, the coded signal that its two kind of reliably and exactly can receive that radio transmission sends is different, can not by the interference of other remote control electrical appliance; Another kind receives programme control circut, connects from storage number end with dialing integrated package of the extension line of telephone key rosette copper paper tinsel.

Dialing integrated package in telephone set has following function, one is to store multiple telephone number, when oneself storage is complete in advance (the present invention can utilize former existing phone to store this integrated circuit), as long as add a trigger pip to its storage pin, this sheet will control to send a phone number dial automatically, so its multiple storage number ends have been connected on the multiple output terminals in reception programme control circut respectively, the dialing output terminal of this integrated circuit has been connected on telephone set, so when starting telephone call, receive the multi-section telephone number that multiple output terminals of programme control circut can start this element storage outwards to dial.The model of a lot of dialing integrated package has powerful storage number function, and a lot of integrated circuit storage capability is all more than 10 numbers, so phone circular function is very powerful.

Be a very serious thing owing to producing telephone call, if wrong report, unnecessary terrified by causing, consequence is very serious.And use now the apparatus of remote control many; as locking of protecting car door; with unblock etc.; all want straighforward operation; just define possible interference source, and after radio transmitter circuit and telephone alarm cooperatively interact, stop interference source; if there is alarm call must be non-normal door, thus substantially increase the confidence level that the present invention reports to the police.

After the invention process, improve the security performance of anti-theft safety door, outstanding advantage is as follows:

1, anti-theft safety door and alarm achieve the combination of science; possesses the advantage of two kinds of protectors; usually both people can be kept outside the door; run into other people when committing a crime; two kinds of warnings can be sent; very significant to " initiatively the protectiveness " that increase anti-theft safety door, so this product finishes the situation of the passive defence of anti-theft safety door completely, improve security personnel's performance of anti-theft safety door all sidedly.

2, the quality of power supply, directly has influence on overall performance.The controllable silicon quick-break formula two ends monitoring for protection source of stable pressure of this measure is monitor, is again protector simultaneously, can also voltage stabilizing.Show:

(1), source of stable pressure voltage regulation result is good.Can provide stable voltage, because this circuit is three end integrated stable voltage circuits, this circuit is a kind of outstanding integrated regulator, and voltage regulation result is good, and again containing multiple protection, so be a kind of outstanding mu balanced circuit.

(2), reliable operation, one is three-terminal voltage-stabilizing collector is a kind of integrated stable voltage circuit of maturation, reliable operation.Two is devices that controllable silicon used in circuit and triode belong to ripe, because of but reliable, three is that each circuit peripheral circuit is simplified, so failure condition is few.
