Double-opening type security device

Technical field

Belong to safety technique field.

Background technology

Allow work that people feel at ease, learn, have a holiday; the security problem of family is crucial; the alarm coordinating with anti-theft safety door is at present of a great variety; but can only be all the protection of a kind of " passive type "; that is: just when having had crime behavior, could produce onsite alarming, rather than just give a warning in the beginning of likely crime.Imagine, if a kind of alarm can make anti-theft safety door have the protection of a kind of " active ", that is: crime just start just give a warning, allowing and reporting to the police in advance, criminal is understood within doors early to be had and prepares and stop in advance, thereby avoids continuing stolen possibility.

Yet form the protection of " active ", but had two hang-ups: the one, how just can make alarm there is standby lead? possessed lead and how to have improved again the dynamics of warning.

The startup of reporting to the police is critical element, direct relation the reliability of reporting to the police and starting, show after deliberation, address this problem, must, make an effort aspect machinery and two, circuit simultaneously, cooperatively interact, the effect that just can obtain, but will use what kind of frame for movement, and what kind of circuit of joining is only best processing method, this is also an important topic that is worth research.

Summary of the invention

The deficiency existing in order to make up alarm, inventor proposes a kind of new technical measures again, coordinate existing patented technology achievement, form a kind of novel protector kind, can prepare the crime stage, just send immediately pre-warning, thereby the state of affairs is prevented in advance, enrich the kind of anti-theft safety door, strengthened the dynamics of reporting to the police.

The technical solution used in the present invention is:

1. double-opening type security device takes out sheet by early warning signal, and early warning electronic circuit is warned sound system in advance, alarming starter, and timing self-locking switch circuit, several parts of alarm sound system form jointly.

Wherein: it is to be made by a sheet metal that early warning signal takes out sheet, is arranged on lockhole place on security door, and lockhole is covered completely, with wire, pre-alarm signal is drawn.

Early warning electronic circuit is by prestage, amplifying stage, and electronic switch level three parts form.

Prestage is to be connected on early warning signal taking-up sheet with one end of wire, and the other end of wire is connected in the base stage of a triode, and the colelctor electrode of this triode is by system power supply, and emitter stage connects the input of amplifying stage.

Amplifying stage consists of with peripheral element jointly a plurality of not gates: with a plurality of not gate inputs, be connected with output, be with the output of first not gate, to have connected the input of second not gate, as the form being connected in series of many not gates of method generation, every not gate input has been connected a resistance with output; With prestage transistor emitter, connected the input of first not gate, the output of last not gate is the output of amplifying stage.

Electronic switch level is to connect together with the input of several not gates, becomes this input, and several non-gate output terminals connect together, and become output at the corresponding levels, and the input of this grade is connected in the output of amplifying stage, and output has connected pre-warning sound system power supply.

Alarming starter consists of a travel switch and lockhole switch.

Lockhole switch is mounted in the hollow position of flange, and early warning signal takes out under sheet, with screw, early warning signal is taken out to sheet and docks with flange, and early warning signal takes out the button that sheet is oppressed lockhole switch; Draw with wire the contact of lockhole switch.

Travel switch is mounted in door and doorframe junction, and after door and doorframe close and close, doorframe is oppressed the button of travel switch, with going between, the contact of travel switch is drawn.

Timing self-locking switch circuit is: after the resistance of lead-in wire series connection with alarming starter, be connected on the base stage of first triode, the grounded emitter line of this triode, colelctor electrode has connect two-way, one of be to join with power supply after having connect a resistance; Two are the one end that connect a resistance, another termination of this resistance the base stage of second triode.

Second transistor collector connect two-way, one of be to have connected after a resistance to be connected on power supply; Two are the one end that connect a feedback capacity, the other end of this feedback capacity has been connected and has been connected on the base stage of first triode after a diode and resistance, also connects a resistance between this end of this feedback capacity and ground;

Second transistor collector outwards exported and drawn holding wire.

Alarming starter has connected the power supply of alarm sound system after timing self-locking switch circuit.

2, lockhole switch is a pocket buttons switch, and its mounting means is to be first welded on a bar printing plate, and printed panel is screwed in lockhole top again.

3, the amplifying stage in early warning electronic circuit is to be formed by two to three not gate strings, and electronic switch is that output and the input by three to four not gates connects together respectively, and not gate adopts integrated circuit 4069.

4, in timing self-lock switch circuit, triode used is high power valve NPN and PNP.

5, the feedback capacity in timing self-lock switch circuit is the form of electrodeless electric capacity that is in series into two capacitance cathodes.

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

1,the existing achievement in research of the present invention is, to opening the door of security door, without mechanical key, but adopt wireless remotecontrol method to open the door, and the lockhole opening the door with mechanical key to be only a kind of backup, when breaking down, just enables, so lockhole can seal.

,effect of the present invention is that a kind of band has levels and has the alarming device of several functions.Be the triggering starting device that has two covers different, two kinds of different warnings, thereby produce two kinds of different effects.

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

The second level protection is to report to the police.Mainly the criminal for the pre-warning of not preventing, or with the barbarous mode person of forcing open the door, now, if think formal damage lock port lid, while entering house by cracking lockhole, to send out and displacement by the shift knob of lockhole cap lower compression, produce warning enabling signal, if forced open the door by barbarous mode, be installed on door with the dry-reed tube switch of doorframe junction because of having surpassed coverage with the distance of magnet, contact changes, and also can produce warning enabling signal, thereby starting warning system will be sent the chimes of doom of deterrent severe and that give great volume.

3. the principle that pre-warning produces is: the early warning signal that touches aspect on lockhole when hand takes out after sheet, touch signal is after the base stage of prestage emitter follower enters, the amplifying stage that enters into this grade amplifies, after having had enough voltage, finally touch electronic switch at the corresponding levels (being that merit at the corresponding levels enters) and remove to promote to warn in advance acoustics circuit.

4, in measure 1, used timing self-lock switch circuit, it has played critical effect, makes each startup of reporting to the police all very reliable, at this, timing self-lock switch circuit is made the following instructions:

When not receiving signal, first transistor collector is high-order, and the current collection of second triode is very low, not output signal.

When on off state changes, signal has been sent to first triode NPN base stage, 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 this circuit also should illustrate following some:

(1) so 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 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 remotecontrol 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 remotecontrol 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 recovery process 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-and feedback resistance has formed charge constant altogether, 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 select 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.

After the invention process, there is following outstanding advantage:

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

2, single for alarm, retained all advantages of existing warning product.

3, 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 people can be kept outside the door; when running into other people and committing a crime; can send two kinds of warnings; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will suppress crime behavior generation; and whether waiting for passively that it destroys) and be all very significant, the situation of the passive defence of anti-theft safety door so this product is through with completely, has promoted security personnel's performance of anti-theft safety door all sidedly.

The switch of 4, 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 owner is absent from the scene is within doors opened (with improper, opening), or opens the door by lockhole with ' key ', is all crime behaviors, and warning is now 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, thereby do not affect the normal work of the each starting of security system.

5, touch pre-warning line road sensitive and reliable, the one, owing to having adopted emitter follower input, improved input internal resistance in the line, so touch signal is easily taked.The 2nd, the amplifying circuit being 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 when hand contact lockhole early warning signal takes out sheet, pre-warning is opened automatically, after hand leaves, automatically closes.

6, used the benefit of timing self-lock switch: the one, relaxed the requirement to switch, reduce the difficulty that switch is installed, increase the attractive in appearance of door.The 2nd, improved sensitivity and the reliability of the starting of reporting to the police.
