Description

Multiple guarantee guard safety door

Technical field

Belong to the electromechanical technical field.

Background technology

Security personnel are both important, and the face that security personnel relate to is also very wide because it is the basis of life, and list is opinion with family, just relates to hundreds of millions families, so have great significance, the inventor is ready to carry out its research with bigger energy, and hope can have effect preferably.

Anti-theft safety door is to can use the most general security personnel's equipment in the society.Its biggest advantage is, it is protecting important within doors access site---Men, if can not crack it, it just can be kept outside the door reliably non-personnel within doors.The user feels safe relieved, and it is also convenient to use simultaneously, it be a kind of most important also be basic and the most essential a kind of protection.

But the anti-theft safety door major defect is a kind of protection of passive type, and its implication is, if objectively unmanned on the scene again, and when the crime behavior is arranged, then can only " passive " and wait for destroyed " helpless ".And the crime behavior has the sound of movement mode of savagely forcing open the door significantly, also there is sound littlely to crack the form that lockhole is started with " civilization ", means are increasing, unsafe factor is strengthening, in allegro today, young man is busy with work, and the old men will go out to lie fallow, situation unmanned in the family is everlasting, and nobody situation also is not difficult to produce all around.So objectively created condition for the crime behavior.The shortcoming that security door exposes also appears gradually.

Imagination if security door has the function of alarm, can obviously can reduce to minimum to loss in advance with the house owner people outside of not accomplished crime behavior announcement.

At present in the product, though there are a lot of alarms, the advantage of alarm is the weakness that can remedy the anti-theft safety door passive protection, its greatest weakness have following some:

1, do not possess non-personnel within doors the most important basic functions of keeping outside the door.

2, a lot of alarms do not possess the function of excellent in performance telephone call, the not outstanding implication one of performance is can not reliably solve the problem of correct identification, as sound letter sensor, can not tell exactly is the sound that sends of people within doors, or the sound that sends of criminal; As the signal that infrared ray sensor takes out, can not tell one of own side or other people accurately, other tactile sensor etc. and for example all exists the problem of accurate resolution.Wrong report brings in terror to the people, and this is in lifely least to want to take place.The 2nd, though or can identify, certain additional program and formality must be increased before each the use, otherwise it is unreliable to report to the police for the second time.The 3rd, be not equipped with no telephone alarm function, namely be there is warning function, but can only be that wherein a receiver is received signal, and can not be that the multi-section receiver is received signal simultaneously that the warning dynamics weakens greatly.These have all seriously influenced the warning function effect.

3, because the starting of reporting to the police is the key element of alarm, whether reliably he directly relate to starting, or malfunction is not arranged.Show after deliberation, address this problem, must work hard simultaneously aspect machinery and two in the circuit, cooperatively interact, the effect that can obtain, but to use what kind of frame for movement, and what kind of circuit of joining be only best processing method, this also is an important topic that is worth research.

4, present senior product often has (maybe must have) wireless link link, and the product radio transmission mainly is to adopt the solid size radiating circuit emission that coding is arranged now, 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 social upward wireless remotecontrol has been widely used in various fields now, as the lock of locking of automobile burglar, all will use remote control, and these all become wide interference source.Also there is artificial instrument interference and cracks.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to serial problems such as cost again, therefore which type of encodes to realize thoroughly to stop all interference in the society with, and reaches cost low purpose again, also becomes a difficult problem.

5, the present invention relates to audible alarm, what kind of circuit, and meet the requirement of simplification, exercisable requirement, but can achieve the goal.

6, good electronic product needs a kind of good voltage-stabilized power supply supporting with it.Because the present invention is a kind of special application product, because its main effect is to realize that phone opens the door, it should be in a kind of armed state at any time, namely is should be in normal duty at any time, otherwise can not opens the door, directly influence life.Obviously supporting with it with the power supply design of ordinary electrical home appliance is to be difficult to reach such purpose, thereby just also can operate as normal during the no alternating current of needs, so this power supply must be furnished with battery, just must must carry out floating charge to it and be furnished with battery.But by traditional method for designing, the contradiction in the time of can not solving battery floating charge and regular picture.Its reason is, if battery tension is nominally 12 volts, and its float charge voltage should be between 13,2 to 13,8 volts science.If according to the method for designing of a lot of products, allow the direct bypass accumulator of alternating current, and by battery again to the work system power supply, whole system on the voltage of floating charge, 12 volt exceeds 1 than normal voltage with long-term work like this.About 4 volts, high if distributor requires, then be difficult to accept.If it is simply that the step-down of battery float charge voltage is low to normal 12 volts, again to system's power supply of joining, produce new contradiction again, because battery is after discharge work a period of time, drop to 12 volts with very fast by higher float charge voltage, therefore when floating charge originally correct voltage falls again with low 1,4 volt, it is undesired to have influenced supporting electronic circuit performance.Thereby now a lot of products can't address this problem.Can only be connected on bridge-type output to battery simply, to the battery floating charge, though solved the correctness of institute's distributor operating voltage like this, can't consider the science of floating charge with bridge rectifier at all.With seriously easily influencing into the life-span of battery, to much requiring the high product of auxiliary products obviously inapplicable.

The society the development, the product needed progress, market demand is enriched the kind of alarm and anti-theft safety door, the new product that more needs anti-theft safety door to combine with alarm, bring to the user safer, more reliable fail-safe.

Need the compound of multiple technologies but address this problem, need the innovation of technology, be difficult to for a long time break through, do not properly settled all the time.

Summary of the invention

Be the clear meaning of understanding the technical program, at first will make the following instructions:

The inventor has done to study for a long period of time to anti-theft safety door, and anti-theft safety door has arrived the stage of following progress:

The firstth, normal door is opened the door without mechanical key, but the mode of opening the door with electronics telecontrol engineering or phone.When normal door, be installed on the power set in the door, will promote the lockset action, realize opening the door.Meanwhile, still kept the form that mechanical key opens the door, its objective is to have a kind of opening the door to remedy when automatic system goes wrong.This namely is if open the door with mechanical key, and great majority are to want also to be the situation that needs telephone call by joining the situation of mechanical key crime.And a few cases is own oneself to want the situation of opening the door with mechanical key because electrical equipment goes wrong, but this situation is own clearly situation on the scene, produces alert sound and oneself does not also feel fearful and nervous.

The secondth, have identification circuit, can correctly identify is the situation of crime behavior or owner's normal door.Its reason is that the behavior of opening the door normally is to open the door with electronic technology, rather than opens the door with mechanical key.When normal method was opened the door with electronics, the identification circuit input had electronic signal, and the no electronic signal of crime behavior identification circuit input will start warning system.

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

One, the switch of pacifying in the measure scheme one is the key component that warning of the present invention starts, and also is a bright spot of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, making warning of the present invention accomplish more science, also is the place different with a lot of alarms, and its reason is:

The firstth, 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 ', all is crime behaviors, and warning at this moment all is very significant.

The secondth, very reliable, because the opening the door at closing time of normal life, do not need artificial additional move, do not influence the normal habits and customs of people, thereby do not influence the operate as normal of the each starting of security system.

The 3rd is that protection is tight, moves into one's husband's household upon marriage in the inlet chamber because the criminal comes round, only may two kinds of methods, and a kind of situation is to open the door and come in jack with barbarous method, a kind of method is to crack behind the lockhole the ABC ofly, but this two method all can be reported to the police.

The 4th is that the warning firing switch is sensitive and reliable, can just report to the police when the crime behavior is not accomplished, thereby loss is reduced to minimum.The initiating signal of reporting to the police because the switch contact when lockhole cap is becoming flexible on the lockhole will change.If in like manner the door and doorframe this be subjected to displacement, the switch of pacifying this place also can start alarm signal immediately.

Two, be positioned on the warning starting on a ground, telephone call adopts wireless remotecontrol to contact with being placed within doors, so telephone call is laid a little arbitrarily, has strengthened confidentiality.

Three, after the processing in the information processing part following function is arranged among the present invention, the one, can store a plurality of telephone numbers, under the situation that oneself storage finishes in advance, (the present invention can utilize former existing phone that this integrated circuit is stored), as long as the starting of programming start device, all storage signals of telephone will be transferred to the phone signal of storing in the phone automatically.And such characteristics are arranged, and the one, together with can both notifying from a phone call each phone, rather than only notify from a phone call wherein one one, improved the dynamics of notifying from a phone call, the 2nd, can listen to on-the-spot certain situation, strengthened telephone alarm function.

Four, the program circuit in this unit can be made of a variety of circuits, the Copper Foil that the Hands-free key of the telephone in its first output and this part is corresponding links to each other, other output links to each other with the key of respectively storing of phone respectively, the program control rule that forms is, first output is the high-order Hands-free key of opening base of output at first, produce the off-hook program, trigger the first storage number pin in the phone again; Call out first receiver conversation; As method repeatedly, all store all receiver numbers in keys can to call out out phone.

Five, each road output of first programme control circut connects the line bag of a relay, the a pair of constant open contact of each relay then connects the pair of lead wires of drawing by in the telephone key dish respectively, each the road output that specifically is first programme control circut has all connected a triode, the colelctor electrode of triode has connected the lower end of relay again, when programme control circut receives that signal has output, drive relay, make the phone action then.

Six, owing to adopted the startup of reporting to the police, the two-part combination closely of telephone call in the technical scheme one, just formed such defence program and protection philosophy, just often anti-theft safety door is kept other people outside the door.And other people are subjected to displacement between door and the doorframe when destroying door by barbarous method, and the switch that is positioned on door and doorframe can send signal.When committing a crime by lockhole, in case open lockhole cap, the no locking press button switch that is loaded between locking closure and the door can be because becoming non-oppression state from oppression state, the constant close contact of no self-locking press button will become the signalling state, no matter that a kind of switch motion of two kinds of switches, through the identification of lines of this bright person in being fruitful, conclude whether this warning.Report to the police if belong to, can produce two functions, a kind of function is to connect to promote alert acoustic-electric source, produces onsite alarming, and caution is caused at the scene, prior a kind of function is to be positioned on the controlled emissions plate radiating circuit starting of security door part, receive transmit after, the warning that produces the multi-section phone, the owner of notice mobile phone, in time determine, with processing.Loss is reduced to minimum, or remedy.

Seven, the timing feedback circuit has played important function in the present invention, and to this, circuit has following explanation:

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, this moment, current collection was very low, second transistor collector is high, output signal, meanwhile, because the positive feedback branch that electric capacity is formed 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, it is high that second transistor collector is always, and signal output is arranged all the time, arrived certain hour after, feedback branch electric capacity differential is full of, feedback branch lost efficacy, so positive feedback is regularly, was not eternal.

For this circuit also should illustrate following some:

So 1 will add positive feedback branch, 3 meanings are arranged, (1), relaxed requirement to switch, namely be that switch can be by of bonding, also can be button-type, and the power of contact is not had influence, so can adopt miniature, to reduce the switch mounting hardness, increase 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 had the action that cracks lockhole, the warning initiating signal was sent in the action of lockhole protection switch, starts the radio remote-controlled circuit starting immediately, allows within doors telephone receive and produces telephone alarm function.If therefore have the people cracking lockhole, (referring to unclamp the behavior of the screw on the 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 be security personnel's products, its wireless remotecontrol all is to adopt many yards radiating circuits, needs the regular hour when emission, if without this circuit, in some cases, just might not guarantee the so long time.And this circuit has been arranged, just can guarantee that the emission of starting each time all is very reliable.Reason three is that the inventor is applied to the series products of ensuring public security, non-one of radio coding integrated circuit, but polylith, this is more much longer than the simple radiating circuit time, feedback branch has been arranged after, that is operation of short duration I guess, can both guarantee to launch required time at every turn.Reason four is to strengthen amplification quantity, has improved the reliability of control 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 this moment, second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of second pipe is fed back the charging of feedback capacity differential, finishes until differential.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, namely be second triode when full, the positive pole of feedback capacity links to each other with ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, satisfies the necessary preparation of feedback next time fully.

3, feedback capacity is little has formed charge constant altogether with feedback resistance, adjustable flexibly, is adapted to dissimilar switches.

4, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is bigger, be that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but select electrodeless electric capacity capacious for use, sometimes be difficult for looking for, and price is higher, so proposed in the measure 6 to become electrodeless method with electrochemical capacitor, choose the method that the negative pole of having used two electrochemical capacitors is connected together among the figure, adopt this method after, capacitance can conveniently make up, and leakage coefficient can improve a lot of a lot, in this programme because the positive feedback circuit is arranged, 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 first pipe, not produce loss of signal branch road to positive feedback branch.

The timing feedback circuit is equivalent to the pecker of switch, and the signal that switch is spread out of amplifies, and passes to next stage again, has guaranteed contact more reliably between system.

Eight, implemented the wireless remote control emission in technical scheme 1 and adopted many yards launch scenarios, 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.Because producing telephone call is a very serious thing, if wrong report, unnecessary terrified with causing, consequence is very serious.And use the apparatus of remote control many now, as locking that the automobile door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the artificial disturbance that just can thoroughly stop this class after many yards.After otherwise many yards radiating circuits have been arranged, must be non-normal door if alarm call is arranged, so have improved the confidence level that the present invention reports to the police greatly.This circuit realizes that its principle of many yards emissions is; When 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 that is connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner have only corresponding section's chip select work.The 3rd, the 4th reason is the same.Since each the coding integrated circuit with or the door mode be input to modulating tube, so form the form of many yards emissions.

Nine, implemented the onsite alarming part in measure, formed such principle, the doorbell sound system unites two into one at circuit and power supply, thus produced following outstanding advantage, one of be that doorbell circuit merges with alarm circuit, the circuit simplification.Two be not occupy between effective appearance of door, can utilize the position of dress doorbell in the original door.Three are the batteries that need not often change doorbell because the doorbell power supply can replace with the AC power of warning system.It is above-mentioned that some is very beneficial for engineering reality.Four, owing to adopted behind such circuit and the position of adorning, warning gives great volume, and can produce to deter effect.

Ten, power supply is an emphasis of the present invention, is directly connected to performance of the present invention.The specific explanations of circuit is as follows:

1, measure meaning summation:

Circuit of the present invention can become three parts from the functional perspective classification, first's output power supply, and general output voltage is nominal battery voltage; Its electric second portion output float charger, this power supply is the required science voltage of floating charge, and is higher by 1 than nominal battery voltage usually.About 4 volts.Third part is electronic switch, and they mainly are the automatic control of implementing battery floating charge and discharge, simultaneously the valuable pressure drop of can not lose battery basically when discharge.

2, the explanation of first's working power:

This part is served as by first three end integrated circuit (661) and peripheral element.It exports three tunnel reason, one of road (662) be that three ends are protected, to the output clamper, output end voltage is higher than about PN joint of input at most.Two circuit (663,664) three end integrated circuit output values are compensated, because the output of three end integrated circuits has had isolating diode (665), reduced by a PN joint, press so three end integrated circuits must improve a PN economize on electricity at output.Three-circuit (665) be isolating diode, it mainly acts on, when no city during by storage battery power supply, by storage battery power supply, because electronic switch is open-minded, must isolate three end integrated circuits, do not produce and flow to the shunting here of three end integrated circuits, this is to saving the electric current of battery preciousness, and is beneficial.This part has formed such operating principle: when civil power, this part work is because these part three end integrated circuits have carried out the compensation of voltage stabilizing value, so exported the operating voltage of nominal, by storage battery power supply the time, this part is not outwards powered and and external isolation.

It should be noted that if nominal battery voltage and floating voltage difference are excessive can increase the number of diode at the earth terminal of this three ends integrated circuit, perhaps string is gone up resistance again.Its relation is, if more than PN joint of difference then string is gone up diode, as difference a PN joint with next string on resistance, at this moment can mainly regulate the operational voltage value that this resistance then can be transferred requiredly.Adopting another benefit of diode is that the diode nominal value is strong, also favourable batch process.

3, the explanation of second portion floating charge part:

This part is served as by second three end integrated circuit (669) and peripheral element.Because float charge voltage is higher than nominal battery voltage 1, about 4 volts, so that the output voltage stabilizing value of transferring these piece three end integrated circuits and first three end integrated circuit are exported voltage is inconsistent.At this moment can adjust the ratio of its peripheral element two resistance (670,671) implements.Its rule is that earth terminal and ground wire series resistance 14 resistances are more big, and then output voltage is more high, and can obtain float charge voltage accurately.

The adjustment of first's working power voltage simultaneously is the same, if output and the nominal battery voltage of three end integrated circuits are excessive, can increase the number of diode at the earth terminal of this three ends integrated circuit, and perhaps string is gone up resistance again.Its relation is, if more than PN joint of difference then string is gone up diode, as difference a PN joint with next string on resistance, at this moment can mainly regulate the operational voltage value that this resistance then can be transferred requiredly.Adopting another benefit of diode is that the diode nominal value is strong, also favourable batch process.

4, third part electronic switch explanation:

When rectifier output voltage, having shown has alternating current, battery to should be the floating charge stage at this moment, at this moment bridge-type voltage is through the transmission of control diode (676), make the base stage of switching tube PNP pipe that voltage be arranged, PNP pipe can conducting and become closed state, the colelctor electrode no-output.The present invention of this stage has only the output of first three end integrated circuit.When bridge-type output no-voltage, from the additional control voltage of bridge rectifier, the electronic switch that the PNP pipe constitutes does not become opening state to PNP pipe base stage.Output of the present invention then comes from the battery discharging power supply.Because above-mentioned reason and principle so electronic switching transistor just can be distinguished the situation that civil power has or not electricity reliably, and are switched two stages of floating charge and battery discharging automatically.Should point out heavily that this pipe PNP pipe is a state automatic control switch pipe not only, and very the more important is arranged, when battery was in discharge condition, this pipe was in saturation state, and the voltage that falls is very low, can not lose the most valuable pressure drop of battery basically.

After the utility model is implemented, security door will present a kind of brand-new looks, and following outstanding advantage is arranged:

One, 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 produce the crime behavior and suppress; and whether waiting for its destruction passively) all be 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.

Two, the warning system partial properties is very excellent, is most valuable for alarm, embodies in the following areas:

The one, warning system can not reported by mistake fully.Because after existing achievement cooperates, has automatic recognition property.The warning that produces when owner is absent from the scene may be the crime behavior only.Otherwise the behavior of not committing a crime, the warning firing switch can not send signal, at this moment because the structures shape of switch is installed.Because the intrinsic property of switch, when shift knob takes place the variation of contact must take place when not suffering oppression being subjected to oppressing.

The 2nd, reliable, its reason one is, the user is closing the door when opening without any need for other additional move, thereby warning system all is in a kind of " highly waiting " state at any time, do not need any preparation, the 2nd, the malfunctioning chance of mechanical switch is far superior to electronic component.

Three are to use conveniently.Do not influence normal habits and customs after the installation fully.If increased trouble with former life, obviously the shortcoming of bringing to the people is or is to use inconvenience, or has forgotten operations necessary and bring the malfunction of warning or malfunctioning.

The 4th, protection is tight, has prevented from directly destroying with barbarous method the possibility of door, has also protected the practice that cracks lockhole.

The 5th, on-the-spot and two kinds of warnings of phone are arranged, deterrent force is bigger, and is used because both complementations respectively have.

Three, single also have following characteristic with regard to telephone call:

One of be the warning great efforts, can store 2 phones sends out simultaneously, such benefit one is to carry out Advise By Wire to 2 personnel, the 2nd, both can call out the mobile phone of carrying, can call out the fixed line phone in relevant place again, can be will reducing to minimum to the various objective factors that are unfavorable for Advise By Wire, even stop fully.

Two be that the multi-section phone of calling out all can be known, stopped to have only limitation that a people knows with may be errorless.
