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

The existing achievement technology of inventor is that normal door no longer needs mechanical key, but open the door with electronics telecontrol engineering, thus lockhole can be covered, but also remain the mode of mechanical key enabling simultaneously, can also open the door with mechanical key if electronic telecontrol is opened the door when there is problem.If stranger wants to enter house by cracking lockhole, hand has just contacted cover plate will produce warning, and oneself because electronic telecontrol goes wrong by the situation that mechanical key opens the door, although warning also can be produced, because one of own side is on the scene, so can not feel alarmed.Also therefore identification circuit can differentiate that to open the door be that the normal door of owner or the preparation of perpetrator crack lockhole and enter room automatically.

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

One, in order to ensure the demand of antitheft series products, continue to do further to promote to power supply, make it to possess that overvoltage, the scope of application are wide, overcurrent time the multi-functional mu balanced circuit that can initiatively show, realize alternating current-direct current and share, ensure the outstanding power supply kind of alarm works fine performance at any time.Spy makes the following instructions multi-functional mu balanced circuit:

(1), the cardinal principle of voltage stabilizing:

Voltage stabilizing adjustment unit is jointly constituted by the Voltage Cortrol branch road that on adjustment triode (103 in Fig. 1), Voltage Cortrol, resistance (104 in Fig. 1), adjustment diode (107 in Fig. 1) form with accurate adjustment resistance (106 in Fig. 1) partially.

Adjustment triode is high back-pressure large power triode, breakdown reverse voltage is greater than 100V, adopt the form of penetrating with exporting, negative feedback is strong, once after the parameter of Voltage Cortrol branch road determines, adjustment triode just exports in order to a definite value, and this definite value can meet the floating charge requirement of electronic DC switch circuit.

(2), there is good overcurrent protection and the explanation of Monitoring Performance:

This unit is shown luminotron (110 in Fig. 1) formed by overcurrent protection resistance (108 in Fig. 1), overcurrent protection triode (109 in Fig. 1), overcurrent.

Produce the principle of overcurrent protection: when support equipment breaks down; electronic component normally in equipment damages; make overall current excessive, the electric current now through overcurrent protection resistance increases, after exceeding the voltage between overcurrent protection transistor emitter and base stage; overcurrent protection triode is open-minded; form the base bleeder current to the adjustment triode in voltage stabilizing adjustment unit, close the output of adjustment triode, now overcurrent display luminotron is luminous; observe for people, timely handling failure.

There is protection automatically and automatic restorability: when overcurrent protective resistance voltage increases, overcurrent protection triode is open-minded, automatically recovers after Failure elimination.

(three), there is the explanation of good overvoltage protection ability:

This unit is made up of anti-thunder tube (102 in Fig. 1), voltage-limiting protection branch road (105 in Fig. 1), overvoltage protection controllable silicon (113 in Fig. 1), triggering stabilivolt (111 in Fig. 1), control electrode resistance (112 in Fig. 1).

In order at thunderstorm season, various electronic equipment power-off need not ensure that it can not damage again, can normally work, and therefore lightning protection and overvoltage are keys.For lightning protection and anti-overvoltage, the present invention has made following measures:

1, overvoltage protection controllable silicon defines fast tripping protection function, has very strong anti-overvoltage capabilities.

The principle formed: cause the output end voltage of voltage stabilizing adjustment unit too high when thunderbolt; and after exceeding the voltage stabilizing value triggering stabilivolt, trigger overvoltage protection controlled silicon conducting, immediately to the base stage clamper of adjustment triode; adjustment triode output voltage is closed, forms the fast tripping protection of lightning protection overvoltage.

Overvoltage protection scr promoter is rapid; can also recover voluntarily, its reason is: the output end voltage once voltage stabilizing adjustment unit is too high, and overvoltage protection controlled silicon conducting has very strong positive feedback; rapidly by the base stage clamper of adjustment triode, can be formed " fast tripping protection function ".And after the output terminal of voltage stabilizing adjustment unit is without overvoltage, can not be formed overvoltage protection controllable silicon and trigger, because trigger stabilivolt to have " door ", thus one of reason that overvoltage protection controllable silicon recovers automatically is become, two are resistance to earth of overvoltage protection SCR control pole, form shunting, greatly reduce the self-sustaining sensitivity of overvoltage protection controllable silicon, theory and test explanation, as long as the adjustment of this resistance is proper, once overvoltage disappears, overvoltage protection controllable silicon will exist without self-sustaining electric current, and automatically revert to off state, if be again struck by lightning, again start, form protection, until output voltage is normal value, when non-overvoltage, overvoltage protection controllable silicon is in " open-circuit condition ", as long as just work when thunderbolt or overvoltage, so be not easy to damage, moment is all in one " backup " guard mode, enhance the reliability of protection.

2, there is voltage-limiting protection branch road, be connected in Voltage Cortrol branch road, when there being thunderbolt overvoltage, again to the base stage voltage stabilizing of adjustment triode, forming the voltage-limiting protection of the output terminal to voltage stabilizing adjustment unit.More than the diode of Voltage Cortrol branch road four of this branch road, namely the voltage of the voltage ratio Voltage Cortrol branch road of voltage-limiting protection branch road is high, and therefore when non-overvoltage, voltage-limiting protection branch road can not conducting, is Status of Backups, can not produces electrical wear.And used be diode, more durable than common stabilivolt, so not fragile.

3, be equipped with anti-thunder tube, the withstand voltage of anti-thunder tube is lower than the reverse breakdown value adjusting triode, and therefore when there being thunderbolt overvoltage, anti-thunder tube preferentially disconnects, and protects the entirety of power supply.

4, adjusting triode is high back-pressure large power triode, and reverse breakdown pressure value, higher than 100V, exceeds 10 times, so have remarkable power of endurance to overvoltage than three conventional end integrated stable voltage circuits.

(4), the explanation of electronic DC switch circuit:

The electronic DC switch circuit be made up of charging resistor (115 in Fig. 1), electric discharge electronic switching tube (117 in Fig. 1), accumulator (116 in Fig. 1), rectify control diode (118 in Fig. 1), base stage controlled resistor (119 in Fig. 1), achieve science floating charge, solve the problem that charging voltage is high and sparking voltage is low, pressure drop can not be produced in battery discharging, decrease the loss of voltage, form sharing of alternating current-direct current.

1, the reason of energy standard floating charge:

The accurate adjustment resistance that adjustment transistor base adjustment diode is gone here and there can carry out Voltage Cortrol within 0.7V, is easy to adjust standard float charge voltage 13.8V.

2, float charge voltage is solved high, and the principle that sparking voltage is low:

(1) electronic switching tube that, discharges is high-power PNP triode, when base voltage is low, PNP triode conducting, one big current flows to collector from the emitter of PNP triode, collector voltage raises, therefore when rectification exports no-voltage, the conducting of electric discharge electronic switching tube, namely accumulator starts electric discharge, why select PNP triode, because pressure drop is very little during its conducting, negligible, so can not produce pressure drop in without alternating current, the collector voltage of discharge diode is equal to battery tension.

(2) and when there being alternating voltage, voltage is directly inputted the base stage of discharge diode by rectify control diode, because the characteristic of PNP triode, base stage has voltage to exist, therefore discharging electronic switching tube can not conducting, so electric discharge electronic switching tube is in cut-off state at ordinary times.

(5) use of diode (120 in Fig. 1), is balanced, when there being Alternating Current Power Supply, the output end voltage of voltage stabilizing adjustment unit is allowed to reduce to available operating voltage, and when only having DC-voltage supply, DC voltage is without balance diode, unnecessary pressure drop can not be produced, realize alternating current-direct current and share.

(6), can in civil power lower ground side's main cause that work with the period: one is the pressure regulation triode in circuit, can not produce additional electrical pressure drop, as long as commutating voltage is higher than output voltage, just can allow this pipe work, with regard to energy voltage stabilizing.(illustrate: if adopt the input voltage expansion scheme that traditional triode is connected with three end integrated circuit, three end integrated circuit must be provided normally to work required voltage, also need triode operation voltage, master creates triode supplementary loss voltage so simultaneously.And when civil power is low, this is valuable voltage).Its two be because of adjustment triode be high inverse-voltage tube, so design time can rectifier output voltage can be designed higher, when civil power is low, at this moment commutating voltage can not export very low, just can do certain compensation.

The explanation of civil power variation range can be expanded: do not damage circuit due to during civil power height, and still can normally work when lower.So extend the working range of city's Electrical change.

Two, the explanation of pre-warning:

The signal amplification circuit be made up of enlarge leadingly triode (02 in Fig. 2), phase inverter, control triode (08 in Fig. 2), driving relay (09 in Fig. 2), the touch signal produced after hand being touched cover plate carries out shaping amplification, be converted into available electric signal, and then start on-the-spot warning circuit, form early warning, wherein phase inverter is made up of first order phase inverter (03 in Fig. 2) and second level phase inverter (06 in Fig. 2).

1, reliable trigger.Enlarge leadingly triode is large power triode, employing is penetrated with output form, there is very strong Feedback polarity, when the base stage of enlarge leadingly triode has faint signal, namely the touch signal produced after hand contact cover plate, the output signal of enlarge leadingly triode passes to phase inverter, the voltage that non-type touch signal is converted to standard by phase inverter exports, and then trigging control triode, start and drive relay, drive relay adhesive, drive relay adhesive contact change and start acoustics circuit, and then produce warning.

2, pre-warning is produced reliable in time.Phase inverter quiescent dissipation is extremely low, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, so when there being trigger pip, pre-warning triggers reliable in time.The sensitivity of phase inverter adjusts very well, and a sensitivity adjustment resistance joined by each phase inverter, i.e. 05 in Fig. 2 and 07, and its sensitivity resistor resistance is large, sensitivity step-down, and resistance is little, and sensitivity raises, and has very strong adjustable.

3, the normally opened contact of relay (09 in Fig. 2) is driven to connect power supply, normal pin contact, as output, drives the application of relay, enhances the reliability triggering late-class circuit (being on-the-spot warning circuit) here, small area analysis can be converted to big current by it, triggers late-class circuit more reliable and more stable.

4, further protection is: warn pre-the criminal failing to prevent; if think that further cracking lockhole enters room; just open cover plate; lockhole switch by cover plate compressing makes shift knob there occurs displacement because of loosening of cover plate; start warning system, thus send formal warning enabling signal.

Three, alarm switch is arranged on two place's key places of antitheft door; be made up of lockhole switch and magnetic switch; lockhole switch is when pre-warning fails to prevent; continue to crack lockhole, cover plate is loosened, the button of lockhole switch no longer starts by the compressing of cover plate; and magnetic switch is cruelty when forcing open the door; door and doorframe displacement and starting, allow anti-theft safety door protect more comprehensively, make warning more scientific.

1, wrong report can not be produced.When house owner people stays out, the enabling now produced is not normal door, if now crack lockhole to open the door, must be crime behavior, warning be now very crucial, and when owner oneself is opened the door by lockhole with key, because oneself is on the scene, therefore can not make us terrified.

2, be very reliable, the normal life custom of people is affected not, in normal enabling is closed the door, alarm switch can not action, thus alarm switch can not damage, and open the door and close the door and also 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 starts at every turn.

3, be that alarm switch is reliably sensitive, just report to the police when crime behavior is not accomplished, thus loss is reduced to minimum.

Four, shoot with video-corder the startup of circuit, form the record to case overall process, comprise criminal motive, crime is passed through.

1, when hand touches cover plate, after signal amplification circuit has had output, will start and shoot with video-corder circuit, shooting with video-corder now is called record before case, 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 the moment of generation automatically can be recorded.

2 and loosen at cover plate, while the switch activated warning of lockhole, also can start and shoot with video-corder circuit, form the record of overall process.

Produce the principle of shooting record overall process: after forcing open the door, lockhole switch or magnetic switch start, although hand have left the theft protection plate above lockhole, but the lockhole shift knob under being pressed in theft protection plate is no longer oppressed by touch sheet, there occurs change, lockhole switch (28 in Fig. 4) is closed, so opened video camera job record.And although door and doorframe are combined rapidly, do not receive correct electronic recognition signal, therefore, report to the police to start and still continue.

Displaying principle is had after shooting record: in Fig. 4,015 is a kind of rest-set flip-flop with display before generation case, thus there is Memorability, each or door has output to open electronic switch (in Fig. 4 016) time, the rest-set flip-flop having memory is triggered in capital, so once after rest-set flip-flop is triggered, additional LED can luminescence display.

In Fig. 4 014 is a kind of instrument and time controller with time controling and display, as long as preset the time, it will output signal, after shooting with video-corder control or door (in Fig. 4 013), open electronic switch (in Fig. 4 016), then allow video camera work.

Five, on-the-spot warning circuit is made up of separation member, has very strong gain, is convenient to install; Give great volume, deterrent force is strong.The power firestreak of on-the-spot warning circuit is provided by signal amplification circuit, alarm switch, therefore can't start at on-the-spot warning circuit at ordinary times, can not damage, possess tracing property.

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

One, improve security personnel's performance of anti-theft safety door all sidedly, stranger can kept outside of the door at ordinary times, when someone commits a crime, can give warning in advance, formally can produce warning again, finish the situation of the passive defence of anti-theft safety door in the past completely.

Two, warning function is reliably outstanding, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, highly sensitive, reliable trigger.Attempt when there being people to destroy lockhole crime, just contact cover plate, early warning type system starts immediately, strengthens the psychological pressure of perpetrator.

Three, record performance of making a video recording is excellent.One is that before case, record is given prominence to the key points.Two is the owners that automatically can show announcement after having record, " can not leak visit ".Three is there occurs to make cases and can record overall process.Four is that shooting records various ways.Five is the time having generation when recording.These 5 meanings have return visit and save time, economize energy, and save device resource etc. number of advantages, really achieving workable feature is.(in the situation of work strain, family can not carry out " return visit " shooting by impunity, more impossible in return visit, watch the much useless record of impunity general).Thus for understanding family public security present situation, very important positive role is had.

Four, startup of reporting to the police is reliably sensitive, and warning can not be reported by mistake, easy to use, dependable performance, and protection is tight, and the installation of alarm switch, can not affect people's work habit at ordinary times, can not affect and open the door normally and close the door.

Five, multi-functional mu balanced circuit can ensure the reliability of alarm, it shows: 1, can provide stable voltage, there is again monitoring effect, if arrange and have fault, initiatively warning immediately, non-fault does not indicate, failure vanishes, stand and both recovered, so more supporting special electronic equipments, meaning is very large.

2, lightning protection and overvoltage capabilities by force, have multiple lightning protection anti-over voltage function, no longer quit work because of thunderstorm season power-off.

3, adapt to wide, high at the voltage that meets accident, can not damage.And at voltage, lower ground side and period also can normally work, and extend the scope of city's electro-mechanical wave.

4, available adjustment exports the voltage stabilizing value that there is decimal in generation, to the floating charge of accumulator science.There is overcurrent protection simultaneously.Be fruitful or other electronic products supporting after have excellent performance.

5, simple in circuits, easily produces and debugging.
