For having a clear understanding of the meaning of the technical program, first will make the following instructions:
It one is that normal door is opened the door without mechanical key that inventor has been fruitful, but the mode of opening the door with electronics telecontrol engineering or phone.When normal door, be installed on the propulsion system in door, will promote lockset action, realization is opened the door.Meanwhile, still retained the form that mechanical key opens the door, its objective is and when automatic system goes wrong, can have a kind of opening the door to make up.This be if opened the door with mechanical key, and great majority are to want by joining the situation of mechanical key crime, are also the situations that needs telephone call.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 oneself and does not also feel fearful and nervous.
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 is normally to open the door by electronic technology, rather than opens the door with mechanical key.When normal method is used electronic open-door, identification circuit input has electronic signal, and the input of crime behavior identification circuit is without electronic signal, will start warning system.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is further explained as follows:
One, the present invention design is that a kind of band has levels and has the alarming device of several functions.
(1), the first level is pre-warning: fundamental purpose is to prevent the heart that has crime, or firm crowd when bud.Function is to rigidly connect and touch above lockhole after cover plate at the hand when crime, 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 of gender neutral language, be to may criminal causing very large psychological pressure, but can not damage being not intended to person, to neighbours, more can not cause in terror, because causing consequence, pre-warning and crime also have very large gap, can produce so very large benefit, be to produce pressure very greatly at heart to criminal, the generation of pre-warning can make him know clearly, in room, early there is preparation, if continued, must there is " below " waiting for, by have thereby hint obliquely at later difficult, probably impel it to stop as early as possible, halt at this point, so played the initiatively effect of protection.
(2), the protection of the second level is warning device; mainly the criminal for the pre-warning of not preventing, if think formal damage lock port lid, while entering house by cracking lockhole; to be subjected to displacement by the shift knob of lockhole cap lower compression, and send formal warning enabling signal.
Two, pre-warning produces principle and effect:
1, touch principle: when no touch signal, the bridge diagram no-output that four electric capacity in communication channel form, the preposition unit of bridge type, no-output.When having touch signal, the bridge diagram parameter generation great change that former four electric capacity form, has alternating current output, has passed through by diode D1, D2, D3, after the rectification circuit that D4 forms, has direct current output, through penetrating with isolated location, amplifying unit has finally encouraged onsite alarming unit after amplifying, thereby has produced the various effects that various functional units produce.
2, circuit is outstanding reliable: sensitive reliable.
(1), the preposition unit of bridge type, performance is good: its reason is when no touch signal, 4 capacitance parameters of electric bridge are consistent, internal current balance, the output of bridge-type output terminal no signal, after hand contact chip, there is serious variation in the capacitance parameter that contains touch sheet end, so output terminal has signal output, bridge diagram and bridge rectifier circuit all belong to classical circuit in circuit, theoretical show with test, and this circuit has very high sensitivity, and circuit is very reliable and stable, for the present invention has established fine basis.
(2), isolated location played matching effect well between the preposition unit of bridge type and amplifier stage, further promoted the performance of measure of the present invention.This grade of the first has very high input impedance, played good buffer action in two-stage.It two is that output impedance is low, and the excitation of rear class is had to very strong surplus.
(3), amplifier stage has outstanding performance.In this grade of unit of the first, the door of NPN triode input is very low, only has 0.7 volts.The 2nd, second three utmost point of this grade have very strong amplifying power, because NPN triode and PNP triode have formed complementary relationship, and the 3rd, second PNP triode of amplifier stage has very strong carrying load ability, formed the form of electronic switch.
(4) it is that operating voltage can have relatively wide scope that, in the present invention active all adopts the benefit of triodes, thereby can save mu balanced circuit in working power, and its benefit has two, the first, and circuit simplifies, more reliable.The secondth, if while adopting three end contain integrated regulator, when civil power changes when too high, fragile.
(5), when no touch signal, system power saving has also reduced having " electrical wear " of element, the reliability of having promoted circuit from another angle simultaneously.
The lockhole switch of three, pacifying in measure scheme one, it is the key component that warning of the present invention starts, also be 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 has been accomplished more scientific, also be the place different from a lot of alarms, 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 operation of the each starting of security system.
The 3rd, warning starting switch is sensitive and reliable, can when crime behavior is not accomplished, just not report to the police, 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 lockhole will change.
Four, in onsite alarming, by a triode, formed the prestage that sound equipment amplifies, by a PNP and NPN triode, formed complementary circuit audio frequency has been carried out to power amplifier, when having pre-alarm signal, 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 efficiency.
Five, in technical scheme 1, implemented wireless remote control radiating circuit, there is important meaning, if remote control be subject to weather and surrounding environment influence large, if can not notify in time personnel outside when there is something special, that is very serious, description of test, the distance of radio controlled transmitting has much relations with size when same circuit.Because it has a great impact with reliability the stable of radio ttransmitter and receiver.Therefore to take following measures: the one, copper foil antenna has been made English lower case n shape, antenna Copper Foil width is 2MM, left and right is the Copper Foil of two vertical parallel shapes, Copper Foil length is 30MM, article two, 20 MM of the distance between the Copper Foil of vertical parallel shape, connect with arc Copper Foil kiss above the Copper Foil of two vertical parallel shapes.The 2nd, the input end of copper foil antenna increases an electric capacity over the ground, copper foil antenna output terminal is that high-frequency emission pipe collector place has increased an electric capacity, one end of electric capacity is that high-frequency emission pipe collector is connected with copper foil antenna output terminal, the electric capacity other end is connected with one end of external antenna, and external antenna has been used the long line of one 1 meter.Two kinds of measures are used jointly, allow transmitting with receive between can realize well and mating, be convenient to installation simultaneously.
Six, in signal conditioning package, have two kinds of electronic circuits, a kind of is radio reception circuit, and the wireless remote control that its energy reliable reception sends from user transmits; Another kind is to receive programme control circut, connects the extension line from telephone key rosette copper paper tinsel, allows the number of storing in telephone set transfer to successively.
Dialing integrated circuit in telephone set has following function, the one, can store a plurality of telephone numbers, in the situation that prior oneself storage is complete (the present invention can utilize former existing phone to store this integrated circuit), as long as being stored to pin, it adds a trigger pip, this sheet will automatically be controlled and send a phone number dial, so being connected on respectively, its a plurality of storage number ends receive on a plurality of output terminals in programme control circut, the dialing output terminal of this integrated circuit has been connected on telephone set, so when starting telephone call, the multi-section telephone number that a plurality of output terminals of reception programme control circut can start this element storage outwards dials.The models of a lot of dialing integrated circuit have powerful storage number function, and a lot of integrated circuit storage capability are all at 10 more than number, so phone circular function is very powerful.
After the invention process, anti-theft security goalkeeper presents a kind of brand-new looks, has following outstanding advantage:
1, 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.
2, Forewarning Measures performance is outstanding reliable, can guarantee this functional effect.Reason one is highly sensitive, can guarantee that early warning system will be started immediately when having people to want to destroy lockhole.The 2nd, load capacity is strong, thereby various effect can fully demonstrate, and the 3rd, circuit is reliable, not fragile.
3, warning system partial properties is very excellent, for alarm, is most valuable, embodies in the following areas:
The one, warning system can not reported by mistake completely.Because after coordinating with existing achievement, there is automatic recognition property.The warning producing when owner is absent from the scene may be only crime behavior.Otherwise the behavior of not committing a crime, switch can not send signal, at this moment because the structures shape of switch is installed.Due to the intrinsic property of switch, when being subject to compressing and not suffering oppression, shift knob there is to occur the variation of contact.
The 2nd, reliable, its reason one is, user is closing the door when opening without any need for other additional move, thereby warning system is at any time all in a kind of " highly waiting " state, do not need any preliminary work, the 2nd, the malfunctioning chance of mechanical switch is far superior to electronic component.
The 3rd, easy to use.After installation, do not affect normal habits and customs completely.If increased trouble with former life, the shortcoming of obviously bringing to people is or is to use inconvenience, or forgotten necessary operation and bring the malfunction of warning or malfunctioning.
The 4th, protection is tight, has laid special stress on protecting the practice that cracks lockhole.
The 5th, advanced in performance, owing to utilizing network platform transmission of information, hurry up, and with people place range-independence, report great efforts, can store multi-section phone, send out mass-sending, such benefit is to carry out Advise By Wire to a plurality of personnel simultaneously, and telephone set can be as warning device when there is something special, general time, it is exactly common communication telephones.
