Abstract

The utility model discloses a safety door with a pre-warning function, and belongs to the technical field of telephone control. On the basis of the safety door, two different types of switches are mounted on two specially treated portions, different treatments are conducted due two the fact that the characteristics of the switches are different, when a criminal commits a crime by breaking the door or through a key hole, a switch contact changes and an alarm is given, a silver-alloy brazing soldering lug is glued on a key hole cover plate, a wire lead of a touch switch is connected to the soldering lug, when the criminal commits the crime, a beam of hard light emitted from inside the safety door is right against the face of the criminal, thus the criminal experiences mental stress, and therefore the crime is prevented before committed. According to the safety door with the pre-warning function, existing patent achievements of inventors are fully used, a novel scheme is put forward, and a broad space is provided for developing door products.

Description

The safety door that has pre-caution

Technical field

The invention belongs to phone control technology field.

Background technology

Security personnel follow safety, and safety is followed happiness, and the safety that improves family is that society is a kind of demand.

Because security personnel are not only important but also relate to hundreds of millions families, to this, the inventor has multinomial achievement, but a good product usually determines success or failure by details, and along with going deep into of research, the existing achievement that I am applied for is done further to replenish with perfect.

At present in security personnel's product, though have a lot of alarms, its greatest weakness have following some:

1, most alarm all is a kind of warning of passive type, its implication is, in flagrant delict just report to the police, and can not just sound a warning immediately when the heart of crime is just arranged, produce and prevent, can only in flagrant delict begin to report to the police, obviously can only be a kind of warning of passive type, this passive warning, the deficiency of generation is tangible.

2, warning in flagrant delict, a lot of alarms do not possess the function of excellent in performance telephone call, and 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 can become weak link on multiple link like this, the warning dynamics weakens greatly.These have all seriously influenced the warning function effect.

3, not possessing the key property of security door, namely is not possess non-personnel within doors, the most important functions of keeping outside the door.

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, and its warning performance accomplishes more initiatively some, can be in advance with the house owner people outside of not accomplished crime behavior announcement, obviously can reduce to minimum to loss, obvious this product also must become a kind of protector assortment class of excellence.

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

The present situation of security door for a change, remedy all weakness that alarm exists, main task of the present invention and purpose are to take full advantage of the existing patent of inventor and technological achievement, a kind of new technical measures are proposed again, form an integral body with above-mentioned achievement, become a kind of anti-theft safety door kind of combined type.The characteristics one of this new product are for alarm; has excellent character; the 2nd, the new product of formation alarm and security door one, opposite house forms system protection again, namely is when opposite house carries out cruelty destruction; door can send caution; when door lock being carried out civilization when destroying, also can produce caution, also may send the signal of prevention especially when might be to antitheft the crime; the state of affairs was prevented before may taking place, thereby become a kind of new more perfect security personnel's kind.

The technical solution used in the present invention is:

1, has the safety door of pre-caution, it is characterized in that: by alarm unit, warn the unit in advance, anti-theft safety door, the common composition.

Wherein: alarm unit is by, warning starter, radio transmitter circuit, and information-processing circuit is formed jointly.

Touching the protection position is a hard sheet, and this sheet covers above lockhole, and the lead of being introduced by the hard sheet is connected to the output of contact witch, and the output of soft-touch control has connected a warning lamp.

The warning starter is: at two parts of security door two switches have been installed respectively, first switch is installed on the shop front of security door activity, be positioned at closure doorframe behind doorframe and can oppress the position of switch one button, connected a pair of pile crown of switch one contact with one side of one group of two lead-in wire, another side is outwards exported; Second switch is installed in the top in door lock hole, upper fixed in the door lock hole has a cover plate, be equipped with the hollow packing ring of certain altitude between cover plate and the door, switch is welded in earlier on the bar printing plate, the copper-clad surface of printed panel has sticked insulant, be installed in then within the hollow packing ring, when cover plate is fixed on the lockhole upper gasket, cover plate will be pushed down shift knob; When cover plate is loosening, separate with the button of switch; One side with two lead-in wires of another group has connected switch contact two pile crowns partly, and the another side of lead-in wire is outwards exported, and the lead-in wire of switch has been connected to a wireless remotecontrol radiating circuit that is contained in the door.

Information-processing circuit is: draw 4 groups of totally 8 lead-in wires from telephone dialing button printed panel Copper Foil matrix, wherein two Copper Foils being connected with the hands-free button of telephone of the termination, one side of first group two lead-in wires are connected; The termination, one side of two lead-in wires of second group and telephone are stored two Copper Foils that a key is connected and are connected; The termination, one side of two lead-in wires of the 3rd group and telephone are stored two Copper Foils that two keys are connected and are connected; The termination, one side of two lead-in wires of the 4th group is connected with two Copper Foils that telephone storage triple bond is connected; 4 groups 8 all another side terminations of lead-in wire respectively be contained in telephone in the end of going into of electronic program control circuit be connected.

Output with wireless remote control receiving device is connected with electronic program circuit start end points.

2, door is travel switch with the switch of doorframe junction, and the switch of lockhole top is no self-locking button P cock.

3, travel switch is to be contained in the square box with screw earlier, and square box is to be connected with screw with the fixed form of door.

4, pre-warning lamp is installed within doors the shop front, and the position is the position of opal.

5, electronic program unit and radio system are to be contained in the improved communication telephones base box.

6, the relay of warning operating part in advance has alarm, and alarm is alert sound or language.

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, and this situation does not belong to improper warning, should get rid of.

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:

1, the scheme of measure 1 of the present invention, be actually triple security personnel's schemes of formation: for the pedestrian that passes by on one's way, security door will be kept outside the door, be first weight, for the people who sprouts the bad heart, when preparation or when souning out, when wanting to commit a crime by lockhole, during soft-touch control, pre-caution starting among the present invention, the caution of generation warning lamp makes it to know the existing preparation of family, prevents action.For criminal intentionally, the starting of reporting to the police produces bigger deterrence, notifies household or personnel outside simultaneously.Such triple protection collection security door and warning one have the advantages that both have, so protection is tight.

2, the measure of taking, single with regard to warning function, also have following characteristics:

Early warning is expressed strong greatly, is a kind of very important protection, and the benefit of generation is initiatively to dissolve a lot of contingent items, and personnel in the minor matter notice man greatly not, and it is unnecessary terrified that personnel are outside produced.

Principle and the function of this part be, the position that touches protection is that the key position of lockhole (it is reported that present way of committing offenses, most applications all are can cross to crack the lockhole place and start with.); attempt by cracking lockhole as the people; also do not have to produce when taking off the action of lid; touch signal imports circuit into by the cover plate of covering the lockhole top and produces warning function immediately, and this function namely is to penetrate beam of intensive light directly to criminal's face in security door, makes the criminal feel psychological pressure; stop crime; at this moment owing to also do not reach the program that cracks lockhole, thereby can avoid consequence in advance, so be a kind of important and special anti-theft protection.

This circuit has been formed high impedance input circuit by two triodes, thus very high sensitivity is arranged, through after the triode of level amplify again and become the power amplifier prestage, functional circuit is made up of controllable silicon, controlled silicon ribbon the needed relay of warning lamp.

Whole circuit has high-gain, circuit letter, reliable high characteristics.

Here it should be noted that, consistent explanations all in textbook, the silicon controlled conducting is to trigger control gate, and by being disconnected silicon controlled anode, but what adopt here is that conducting triggers the silicon controlled control gate, and allow controllable silicon end the way that adopts the clamper control gate, test shows it is feasible, in theory also is correct, and its reason is for one-way SCR, anode flows into the electric current of negative electrode, very major part is to enter negative electrode behind the anode process internal control grid, in case the control gate short circuit, cathode current own reduces, the characteristic of controllable silicon itself will cause strong negative-feedback again simultaneously, silicon controlled be produced end.So the present invention in the physical process that this circuit forms is, when prestage is output as a high position, controllable silicon is triggered, the relay adhesive, warning lamp is bright, produces the caution effect, and controllable silicon ends immediately when for low level, relay electric-loss and warning lamp puts out.Whole process is all automatic, warns with touch, and behavior termination and warning lamp are from putting out.

Warning lamp is on the door that is contained within doors, and the opal of light through moving into one's husband's household upon marriage penetrates, and can directly impinge upon possibility criminal's the very big warning function of generation on the face, and the passerby is not produced what effect of doing.

3, being the switch of reporting to the police and starting, 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 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 ', all is crime behaviors, and warning at this moment all is 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 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, 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, 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.

The function relevant issues of the telephone call that 4, produces are described as follows:

(1), in the common communication telephones in market, generally all have the storage function of number, telephone design this function argument be can be used for easily number increasing contact between the kith and kin with emotional affection.But the present invention has utilized this storage function of telephone just, change and store thinking, play emotional affection number used multidigit password with originally being designed to store, change the number that is stored as the multi-section mobile phone respectively into, thereby created important prerequisite for the invention process measure one.

(2), two kinds of electronic circuits have also been increased owing to being equipped with in the telephone.A kind of is the radio reception circuit, it can reliably receive the radio signal of sending in the anti-theft safety door, another kind is that a kind of electronics journey is filled control circuit, and the logic function of this electronic program circuit is to contact by the lead-out wire of 4 groups of buttons in the measure 1, the at first instantaneous Hands-free key of opening, then open and store button one key, behind the certain hour, close Hands-free key again, realize the open-minded of the cycle first time, to realize the call to a mobile phone of being stored.And then again by similar program, open and store the mobile phone that two keys are stored, form the call dialing to second storage phone, in like manner, open triple bond and store key, circulation up to termination, is finished the call to 3 mobile phones or base so repeatedly.Mainly to act on be the starting point of control electronics sequence circuit to the radio reception circuit in the telephone, and in a single day he receive signal, just can send instruction, allows sequence circuit start and start working.

(3), for above-mentioned reasons, so the formed telephone call of the present invention is distinguished be, can form the repeatedly calling to each machine, to alternately calling out of 3 machines, can only report a people and know all disadvantages of bringing so stopped a lot of telephone calls fully.

(4) and technical scheme proposed by the invention is one of a kind of mode of producing, and the another kind of mode of producing in batches is, can form new integrated circuit to the circuits such as dialing of programme-control part and telephone, and more be conducive to produce and reduce cost.

After the invention process, the anti-theft security goalkeeper presents a kind of brand-new looks, and following outstanding advantage is arranged:

1, after the invention process, anti-theft safety door and alarm have been realized the combination of science, have possessed the advantage of 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.Two big benefits one like this are; increase " initiatively protectiveness " function 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 fully; promoted security personnel's performance of anti-theft safety door all sidedly; the 2nd, increased the active warning of warning function; its meaning is; in the time may criminal motive being arranged, just can send caution, prevent it to continue, and do not really want the beginning of warning by the time.

2, warning function is powerful, produces serial characteristics: the one, there is not lockhole on the security door, and can not bring out crime thought.The 2nd, concerning the people that may commit a crime,, to may the criminal then producing very big psychological pressure, prevent the continuation of crime, so can ease contradictions in advance.The 3rd, inoperative to the pedestrian, therefore do not make widely known, do not influence environment.

3, 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 can be 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.

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

One of be the warning great efforts, can store the multi-section phone, mass-sending simultaneously, such benefit one is to carry out Advise By Wire to a plurality of 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.

Three persons that are the acknowledge(ment) signal can hear language or the alert sound of warning, and can listen to the scene.

Four be easy production, the one because report to the police part and telephone unification, can save many circuit, as general off-hook element circuit, store the keypad of number etc., and the part that increases is very limited, the 2nd, used element all belongs to part commonly used.

Five, can accomplish a tractor serves several purposes, the telephone after the repacking namely is a kind of telephone alarm, but still has kept all properties of telephone, still can make communication telephones usefulness, such largest benefit is that family does not have too much device ornaments and to influence family attractive in appearance.
