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 power set 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 is largely crime behavior, now do not input correct electronic signal, warning will be started.

To the meaning of each technical measures, be explained as follows further:

The use in the floating current source of band display, can show after burglary-resisting installation is short-circuited fault in " initiatively ", ensures that burglary-resisting installation possesses good service behaviour at any time.

The enforcement of early warning type monitoring burglary-resisting installation, is not only and produces pre-warning, also possess record before concluding a case, and pre-warning fails to prevent, and formally can not only report to the police, also can record the process that case occurs, be convenient to people and watch in the future.Video recorder wherein and onsite alarming just just start when there being case, at ordinary times can't action, therefore also can not produce damage.

One, the explanation in the floating current source of band display:

1, the reason of energy voltage stabilizing:

Voltage Cortrol triode (8 in Fig. 1) have employed the form of penetrating with exporting, its emitter voltage poorer than base stage 0.7 volt all the time, and have nothing to do with collector voltage, once after carrying out voltage stabilizing to base stage, Voltage Cortrol triode (8 in Fig. 1) just can be stabilized in and be similar on the voltage of base stage, and this numerical value can meet the needs of institute's suitable electronic device.

2, this circuit has overcurrent protection and monitoring two kinds of functions.

This circuit has overcurrent protection function: after supporting equipment generating device damages, the fault of normal generation is that complete machine electric current increases, electric current through overcurrent protection resistance (9 in Fig. 1) increases, when after the emitter stage exceeding overcurrent protection triode (12 in Fig. 1) and base voltage, this overcurrent protection triode can form forward conduction, and amplify, and the base bleeder current to Voltage Cortrol triode, thus close the output of Voltage Cortrol triode (8 in Fig. 1), the shunting route of base stage is from the emitter stage of overcurrent protection triode (12 Fig. 1) to colelctor electrode, and to ground wire after overcurrent protection monitoring indicator lamp (13 in Fig. 1).

This circuit can become a kind of reason of monitoring observation device; after its load is excessive, overcurrent protection action, overcurrent protection triode (12 in Fig. 1) is open-minded; go here and there in overcurrent protection monitoring indicator lamp (13 in Fig. 1) of overcurrent protection triode (12 in Fig. 1) bright, luminous for people's observation.

After this measure is implemented, another feature of circuit is, when there being fault, protection is formed automatically, and overcurrent protection monitoring indicator lamp (13 in Fig. 1) is luminous, and during failure vanishes, automatically recovers.Its reason is that load current is large, and flowing through overcurrent protection resistance (9 in Fig. 1) voltage increases, and overcurrent protection triode (12 in Fig. 1) is automatically open-minded, automatically recovers after Failure elimination.Had this feature, can get rid of a lot of accidentalia, equipment can not produce mistakenly stop, does not affect normal work.

3, the overvoltage capabilities of this circuit is more much better than than three present end integrated circuits, normally can work at thundery sky, and need not power-off, its reason have following some:

One is that the base stage voltage-stabiliser tube of Voltage Cortrol triode (8 in Fig. 1) adopts face bonded type diode, instead of adopts common voltage-stabiliser tube, not fragile.Two is export the voltage accurate adjustment resistance in adjustable voltage stabilizing branch road, and (11 in Fig. 1) is little due to the resistance of this resistance, does not namely affect the voltage regulation result to Voltage Cortrol triode (8 in Fig. 1), but really plays great role to enhancing overvoltage effect.Four is be still face in conjunction with diode in voltage-stabilizing protection unit, not only not fragile, and is be connected on to export in adjustable voltage stabilizing branch road, saves number of diodes.Four is that the former is generally hundreds of volt because the back-pressure of Voltage Cortrol triode (8 in Fig. 1) is much higher more than three end integrated stable voltage circuits, and the latter only 30 volts.Five is be equipped with anti-thunder tube, and this pipe breakdown protection voltage is tens of volt, after coordinating, thus has very large surplus with the Voltage Cortrol triode of high-power high back-pressure.

4, the reason that works under being formed in very wide civil power of this circuit:

Due to this circuit, not to be afraid of input voltage too high, and adjust higher so input voltage can be established when designing, when civil power is low, at this moment rectification can not export very low, just can do certain compensation.

5, the reason of different output voltage stabilizing values can be adjusted.Owing to exporting in adjustable voltage stabilizing branch road, the pressure drop of voltage coarse adjustment diode (10 in Fig. 1) is leading role, so can coarse adjustment be formed, and ratio shared by the resistance of going here and there is very little, so accurate adjustment also can be done, the benefit of accurate adjustment be can furnishing to the voltage for decimal point of the standard needed for battery floating charge.

6, more convenient to the adjustment exporting voltage stabilizing value, be 0.7 volt owing to exporting the face of connecting in adjustable voltage stabilizing branch road in conjunction with each voltage stabilizing value of diode, there is reliable uniformity, can accomplish and adjust more accurately, and resistance can Voltage Cortrol within 0.7, favourable like this batch production.

7, the explanation of direct current charge-discharge unit:

The first, the emitter voltage of Voltage Cortrol triode and the voltage of floating charge output point can adjust to standard float charge voltage, because voltage accurate adjustment resistance can adjust the voltage of below 0.7V, so adjustment easily, realize science floating charge, floating charge resistance (14 in Fig. 1) mainly plays two effects, and one is to large power supply current limliting, two is that the voltage realized between floating charge output point and battery (18 in Fig. 1) is isolated, thus when there being interchange, both can floating charge, can working power be become again.

The second, battery tension is standard 12V voltage, but when alternating current-direct current mixing, battery standard float charge voltage is 13.6V, but voltage exports as 12V during battery discharging, both during charge and discharge, voltage is inconsistent, and direct current charge-discharge unit of the present invention solves this problem well, because discharge diode (17 in Fig. 1) is PNP pipe, during its conducting and battery discharging time, the pressure drop of discharge diode is very little, can ignore, and can not produce very large pressure drop, make battery discharging triode with it, valuable pressure drop can not be lost.

Forming the principle of discharge and recharge is: the base stage of discharge diode is connected to resistance to earth (16 in Fig. 1) and exports with a rectification and control diode (15 in Fig. 1), this circuit just has such principle: when rectification output cathode has voltage, just show now have alternating current to exist, battery should be floating charge phenomenon, discharge diode is because be PNP pipe, its base stage has voltage to exist, and can not conducting, and colelctor electrode would not have voltage to export.When rectification output cathode no-voltage, discharge diode base stage no-voltage, it just constitutes the form of an electronic switch, forms conducting state, and battery starts electric discharge, colelctor electrode output voltage, reliably distinguishes two stages of floating charge and battery discharging.

Three, balance diode to play an important role in this circuit arrangement, because the standard float charge voltage of battery is 13.6V, and operating voltage should be consistent with battery tension, just be unlikely to, because to have a power failure and storage battery forces down and makes equipment not work or cisco unity malfunction, therefore to increase the number of balance diode, float charge voltage 13.6V is reduced to about 12V, when having alternating current, equipment normally works, during battery, arrange and standby also normally to work.And diode is the 0.7V of constant substantially, fine debugging, its dynamic electric resistor is little, little to load effect, can not produce output voltage fluctuation, thus ensure that the correctness that alternating voltage exports, and when storage battery power supply, only through the discharge diode that pressure drop is little, without balance diode, so pressure drop can not be produced, therefore ensure that combined-voltage exports stable.

Two, the generation principle of pre-warning: just send pre-warning at the beginning of crime, now also far from generation consequence, warning can allow crime personnel receive hand in advance, is that of avoiding generation consequence in very large degree.

When people is when contacting contact chip, can produce touch signal, it is very faint only to manage this signal, and nonstandard, after but the shaping that have passed through prestage amplification and integrated amplification is amplified, become the available signal of telecommunication, in contact chip, also add AC signal, make contact chip more reliably sensitive, because inductance capacitance is connected between rectification input and contact chip, by an inductance capacitance, make contact chip add AC signal, can not danger be produced again when human contact's contact chip.

In signal amplification circuit, it is used two triodes to penetrate with amplification that prestage is amplified, the multiplication factor of triode is high, and powerful triode selected by triode herein, therefore, even very faint signal, but also can obtain the amplifying signal of very large multiple, shaping again through integrated circuit is amplified, and makes signal amplification circuit export high pressure, thus starts on-the-spot warning circuit and send warning, and start and shoot with video-corder circuit and carry out record, because now or crime at the beginning of, so warning is now called pre-warning, now be recorded as record before case.

Three, formal generation principle of reporting to the police: alarm switch is made up of jointly door switch and lock-switch, be arranged on two place's key places of anti-theft safety door, lock-switch is arranged on above door lock hole, below contact chip, and door switch is arranged on door and doorframe junction, fail in the crime behavior of prevention in pre-warning, alarm switch starts the key of reporting to the police.

Pre-warning fail prevent crime behavior, if continue to crack lockhole, when contact chip souththern pine moves, the button of alarm switch no longer makes contact change by the compressing of contact chip, thus produce warning enabling signal, if cruelty is forced open the door, door switch contact changes immediately, while encouraging on-the-spot warning circuit to send on-the-spot warning, start and shoot with video-corder the record that circuit forms overall process.

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.

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

1,011 in Fig. 4 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. 4 010), open electronic switch (in Fig. 4 013), then allow video camera work.

2, the principle of shooting record overall process is produced: although hand have left the theft protection plate above lockhole after forcing open the door, but the lockhole shift knob under being pressed in theft protection plate is no longer oppressed by touch sheet, there occurs change, lockhole switch (017 in Fig. 4) is closed, so opened video camera logging.

Displaying principle is had after shooting record: in Fig. 4,012 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. 4 013) 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.

3, the principle of shooting record writing time before generation case: shoot with video-corder control or door when having output to open electronic switch at every turn, have signal to trigger time controller, so the moment of generation automatically can be recorded.

Five, on-the-spot attention device: the prestage being constituted sound equipment amplification by a triode, constitute complementary circuit by a PNP and NPN triode and power amplifier is carried out to audio frequency, when there being pre-alarm signal, it exports the power supply controlling to have opened this part, so there are voice to produce, what form due to this circuit is an OTL instead of OCL circuit, so debugging is simple, and have element not perishable, and the advantage that efficiency is higher.

After this measure is implemented, improve the security performance of anti-theft safety door, outstanding advantage is as follows:

One, after implementing, possessed warning function, shooting-recording function, formal warning function, improved security personnel's performance of anti-theft safety door all sidedly, enriched the kind of security door.

Two, Forewarning Measures excellent performance can ensure this functional effect.Reason is highly sensitive, can ensure that pre-warning circuit will start immediately when there being people to want to destroy lockhole.

Three, record performance of making a video recording is excellent.One is that record is given prominence to the key points before case, and two is the owners that automatically can show announcement after having record, " can not leak visit ", and three is there occurs to make cases and can record overall process, and four is that shooting records various ways, and 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, alarm switch is reliably sensitive, can not report by mistake.Because after coordinating with existing achievement, there is automatic recognition property.The warning produced when owner is absent from the scene may be only crime behavior.Otherwise behavior of not committing a crime, alarm switch can not send signal, at this moment because install the structures shape of alarm switch.Due to the intrinsic property of alarm switch, there is inherently to occur the change of contact when alarm switch button is being subject to compressing and is not suffering oppression, thus start warning.

Five, the use in the floating current source of band display, can " initiatively " show after burglary-resisting installation is short-circuited fault, ensure that burglary-resisting installation possesses good service behaviour at any time, its advantage is as follows: 1, the floating current source of band display, stable voltage can be provided, again to arrange and standby serve monitoring effect, if arrange standby breaking down, source current is increased, overcurrent protection monitoring indicator lamp sends light warning immediately, and when being fault-free at ordinary times, warning can not be produced, if supporting security personnel's product, avoid the security personnel do not known because of power failure blank.

2, lightning protection and overvoltage capabilities strong, can not quit work because of thundery sky, selected anti-thunder tube is resistance to be pressed between tens volts, exceed and disconnected immediately, the component wear in power supply can not be made because of being struck by lightning, and triode used in power supply is high back-pressure large power triode, that can bear is resistance toly pressed in hundreds of volt, greatly exceed three traditional end integrated stable voltage circuits.

3, anti-overflow is effective, and protection is large, reduces the heating degree of Voltage Cortrol triode.

4, adaptive faculty is strong, and the place high at civil power can not be damaged, and the place low at civil power also can normally work.

5, easy to adjust, achieve the science floating charge to battery, there is overcurrent protection ability simultaneously.Applicability is strong, easy-to-use supporting with other electronic product, strengthens the performance of electronic product.
