Description

The protection type intelligent anti-theft apparatus

Technical field

Belong to household electrical appliance technical field.

Background technology

Anti-theft safety door is the protector of each family's indispensability; but anti-theft safety door can only be the protection of passive type; do not possess the performance that the people is kept outside of the door; so it is far from being enough only having the passivity protection of door; alarm has just become the commonly used antitheft equipment that coordinates with door; can make up the some shortcomings of anti-theft safety door, but want to become outstanding antitheft series products, it is inadequate that alarm is only arranged.

The kind of alarm is a lot of at present; but most products all only has in flagrant delict and is just producing onsite alarming; if imagination just begins crime; just sound a warning; producing a very large benefit is because " from succeeding " has very large lead, and the criminal is understood within doors early has preparation, and " risk " is very large; thereby can receive as early as possible hand, thereby become a kind of " protection initiatively ".And the product with such " initiatively protection " type also lacks very much.

Present senior product often has (maybe must have) wireless link link, mainly to adopt the solid size radiating circuit emission that coding is arranged and produce now the device radio transmission, this is feasible for general household electrical appliances, but can not satisfy the requirement of precision for the product of higher gears, not only because existing wireless remotecontrol socially has been widely used in various fields, as the lock of locking of automobile burglar, all will use remote control, and these all become wide interference source.Also exist artificial instrument to disturb and crack.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to again the series of problems such as cost, therefore which type of encodes to realize thoroughly to stop all interference in society with, and reaches cost low purpose again, also becomes a difficult problem.

Now to the meaning of each technical measures of the present invention, concrete condition further is explained as follows:

One,Be the clear meaning of understanding the technical program, at first will make the following instructions: the existing achievement in research of the present invention is, to opening the door of security door, without mechanical key, but adopt the wireless remotecontrol method to open the door, and be only a kind of backup with the lockhole that mechanical key opens the door, just enable when breaking down, so lockhole can seal.

Two,Effect of the present invention is that a kind of band has levels and the alarming device of several functions is arranged.Be that the two different triggering starting devices of cover are arranged, two kinds of different cautions, thereby produce two kinds of different effects.

The first level is pre-caution: main purpose is to prevent the heart that crime is arranged, or firm crowd when bud.Function is to rigidly connect at the hand when crime to touch after above lockhole, early warning signal takes out sheet, sound system will send pre-caution, this caution is more neutral, can send " please noting " as the sound, or language such as " please not staying at this " is prevented, benefit one with gender neutral language is will cause very large psychological pressure to the criminal, the 2nd, can not damage being not intended to the person, and the 3rd, more can not cause in terror the neighbours.

The second level protection is to report to the police.Mainly for not preventing the criminal of the pre-caution of living, at this moment, if think formal damage lock port lid, when entering house by cracking lockhole, to send out and displacement by the shift knob of lockhole cap lower compression, thereby the starting warning system will be sent chimes of doom severe and deterrent that give great volume.

Three, the principle of pre-caution generation is: touch the early warning signal taking-up sheet of aspect on lockhole when hand after, after the base stage of touch signal process prestage emitter follower enters, the amplifying stage that enters into this grade amplifies, after enough voltage has been arranged, touch at last electronic switch at the corresponding levels (being that merit at the corresponding levels enters) and remove to promote to warn in advance acoustics circuit.

Four, the sound equipment principle is: be comprised of a triode prestage that sound equipment amplifies, formed complementary circuit by a PNP and NPN triode audio frequency has been carried out 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 efficient.

Five, implemented the wireless remote control emission in technical scheme 1 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 firing 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 begins telephone call within doors.Be a very serious thing owing to producing telephone call, if wrong report, unnecessary terrified with 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 disturbances 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 that connects 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 modulating tube, so form the form of multi-code transmitter.

Six, two kinds of electronic circuits are arranged in information processor, a kind of is the radio reception circuit, and it can transmit from the wireless remotecontrol that the user sends by reliable reception; Another kind is to receive programme control circut, connects the lead-out wire from telephone key rosette copper paper tinsel, allows the number of storing in telephone transfer to successively.

Seven, hybrid source of stable pressure is significant in the present invention, and the spy is explained as follows power circuit:

1, the reason that has good anti-lightning effect: when thunderbolt is arranged, being usually power supply perishable the time, is that take the to cut off the power supply mode in source is avoided as common household electrical appliances, because these class household electrical appliances are made interim power down process, can not produce serious consequence.But as the specialities of security personnel's class, will become security personnel as resolute power down source blank, be first emphasis of the present invention so improve lightning protection effect.

The first, overvoltage voltage-limiting protection second unit and overvoltage fast tripping protection first module, formed " fast tripping protection function ", and excellent performance has very strong lightning protection overvoltage capabilities.

(1), the principle that forms is: if thunderbolt and when causing output too high and after surpassing the door of diac (6); silicon controlled trigger element voltage-stabiliser tube (6) conducting; thereby triggering controllable silicon (4) conducting; immediately to the base stage short circuit of the triode (5) in overvoltage voltage-limiting protection first module; make the complete no-output of this pipe; three end integrated circuit input no-voltages form lightning protection overvoltage fast tripping protection.

(2), why be called " fast tripping protection function ", in case be because output when too high, controlled silicon conducting has very strong positive feedback, can will adjust the base stage short circuit of pipe rapidly, protection whole process is both very rapid, and protection thoroughly.Realize sealing up a door fully.

(3), the automatic restorability of protection controllable silicon is good.Reason is after producing protection, triode in first module (5) no-output, and triggerless voltage, the controllable silicon anode has resistance in addition; to automatically lose the self-sustaining electric current, revert to voluntarily open-circuit condition, if again be struck by lightning; again start, form protection, until output voltage is normal value.

(4), the controllable silicon that shields and peripherally trigger " the fast tripping protection function " that part forms be in " open-circuit condition " when work, as long as just work when thunderbolt or overvoltage, so be not easy to damage, all be in a kind of guard mode constantly.

Its reason is power output end when being normal condition, and controllable silicon is in off state, there is no " electrical wear ", can not damage.Its external trigger is enclosed part voltage-stabiliser tube voltage stabilizing value higher than output end voltage, so also be in open-circuit condition, there is no " electrical wear ", also can not damage, and all can be at any time a kind of " armed state ".

The second, overvoltage voltage-limiting protection first module has formed the secondary voltage-limiting protection function of anti-lightning protection to thunderbolt, further perfect protection to integrated circuit.

Its reason is, the base stage of triode (5) has Zener diode over the ground, therefore should pipe output by clamper, pressure limiting has been carried out in shoving that this diode pair thunderbolt produces, and is the further Supplementary and perfect to " fast tripping protection ".

2, the reason one that can not damage circuit in the higher place of civil power and period is that civil power can not gush pressure higher than thunderbolt when high, the 2nd, and triode (5) is that high inverse-voltage tube has very strong back-pressure value.

3, can be in the main cause of the lower place of civil power and period work: because preposition triode is high inverse-voltage tube, so can design the bridge-type output voltage higherly when design, when civil power was low, at this moment bridge-type voltage can not be very low, just can do certain compensation.

4, can adjust the reason of different output voltage stabilizing values.Owing to having increased peripheral element adjustable resistance (9) and (10) in measure, thereby can be on reference voltage, realize that again output voltage adjusts flexibly, to realize the normal voltage required to the battery floating charge, as 6.6 volts; 12.8 volt, etc.

After the invention process, following outstanding advantage is arranged:

1, in the present invention, hybrid source of stable pressure used has following advantage:

(1), anti-thunder and overvoltage protection effect are fine.So at thunderstorm season, needn't make power down process, institute's adapted equipment can be because thundery sky quit work, if be used on security personnel's equipment, guaranteed that " security personnel " do not produce blank, and be difficult to reach this effect with three traditional end integrated circuits and uniting of triode.

(2), this line thunder protection effect is more much better than anti-thunder tube commonly used.Its reason one is that lightning protection function is and rear class quick-break rather than shorted to earth, to prime without negative role.The 2nd, the model of the anti-thunder tube that " suctioning through voltage " is low is difficult for having bought, and the model scope of diac of the present invention 6 is extremely wide, is easy to required " suctioning through " magnitude of voltage of supporting one-tenth, suctions through 30 volts of following protections of voltage so be easy to supporting one-tenth.The 3rd, the present invention has " quick-break " and pressure limiting duplicate protection, thereby effective.

(3), adapt to widely, than traditional voltage-stabilized power supply, wider adaptive capacity is arranged, high at the voltage that meets accident, can not damage.And also can work in voltage lower place and period.

(4), there is the voltage stabilizing value of decimal in available adjustment output generation, be convenient to the floating charge of battery science.Has simultaneously overcurrent protection.Be fruitful or other electronic products have excellent performance after supporting.

(5), voltage regulation performance is excellent, because it has all advantages of three end integrated regulated power supplies.

(6), easily produce.Reason one has adopted complex function, and simple in circuits is compact; The 2nd, because the debug point in circuit is few.The 3rd,, debug point very easily quantizes, and the debugging scope is loose.

(7), cheap, cheap more a lot of than a lot of satisfactory a lot of voltage-stabilized power supplies.

2, telephone can as warning device, general the time, be exactly common communication telephones when there is something special.

3, improve the defence rank, more paid attention to the idea of putting prevention first.Can prevent the symptom of a trend that much may occur in advance.The reason one that why can reach this purpose is, hand rigidly connects when touching locking closure, and (it is reported, be the main channel of committing a crime at present by cracking the lockhole crime) may be only the beginning that the heart of crime has just been arranged, if stopped immediately crime, can not produce such or such consequence.The 2nd, this caution will produce very large pressure at heart to the criminal's, because the criminal knows very well, this distance from " succeeding " is also far, and will be very large if crime continues certainly " risk ".

4, single for alarm, kept all advantages of existing warning product.

5, after the invention process; anti-theft safety door and alarm have been realized the combination of science; the advantage that has possessed two kinds of protectors; usually both can keep the people outside the door; when running into other people and committing a crime; can send two kinds of cautions; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will suppress the crime behavior generation; and whether waiting for passively its destruction) be all very significant, the situation of the passive defence of anti-theft safety door so this product is through with has fully promoted security personnel's performance of anti-theft safety door all sidedly.

The switch of 6, pacifying in measure scheme one is the key component that warning of the present invention starts, and is also a bright spot of putting of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, warning of the present invention having been accomplished more scientific, is also the place different from a lot of alarms, and its reason is:

The one, can generation not make us terrified wrong report, this is the most important.Its reason is, the door that is absent from the scene of owner is opened (opening with improper door) within doors, or opens the door by lockhole with ' key ', is all crime behaviors, and warning at this moment is all very significant.

The 2nd, very reliable because the opening the door at closing time of normal life, do not need artificial additional move, do not affect the normal habits and customs of people, thus do not affect the each starting of security system normal operation.

7, the pre-warning line of touch road is sensitive and reliable, and the one, in the line owing to having adopted emitter follower input, improved the input internal resistance, so touch signal is easily taked.The 2nd, the amplifying circuit that is comprised of a plurality of not gates has higher multiplication factor.The 3rd, circuit is simplified, and this part adopts an integrated circuit 4069 just can implement.The 4th, power amplifier is served as by a plurality of not gates, has stronger power, and reliable.The 5th, this circuit is strong from motion tracking in addition, and pre-caution is opened automatically when hand contact lockhole early warning signal takes out sheet, autoshutdown after hand leaves,

8, emission is used many yards, has stopped to exist in society various electrical equipment to disturb.

9, the line power of sound equipment caution system is large, and is simple, and debugging is convenient, power saving.
