For having a clear understanding of the meaning of the technical program, first will make the following instructions:

Present inventor is studied to security door, and present stage is open the 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.

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 alarm of several functions.

Its first function is those people that may commit a crime of warning, this function is exactly: when the hand of crime rigidly connects, touch above lockhole after cover plate, 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 " prevents, by the benefit one of " neutrality " language, be impossible to being not intended to person, damage, because do not send excessive language.

The 2nd, to criminal, but can cause very large psychological pressure, the generation of its such warning of reason can make him know clearly, early has preparation in room, if continued, must there is " below " waiting for, by having thereby hinting obliquely at later risk and difficult, produce and halt the idea into very wise move at this point.

So played the initiatively effect of protection.

The 3rd, this warning can more or not cause in terror neighbours, so the problem that scientifically technical solution background proposes.

Two, the principle that pre-warning produces is: when criminal's hand touches after the signal leading sheet of lockhole top, just be imported in the in-phase end of operational amplifier of the first order and amplify, being input to again afterwards comparison amplifier further amplifies, this have a very large gain, can fully guarantee sensitivity and the reliability of pre-alarm signal.

Its reason is in this circuit, the resistance of first order operational amplifier (in accompanying drawing 1 103) can be adjusted the gain of this grade flexibly, and the divider resistance ratio (106 in accompanying drawing 1) of adjusting the comparison amplifier end of oppisite phase that second level operational amplifier forms can be adjusted again the gain of this grade flexibly.

Three, the principle of alarming starter is: when there being people to force open the door by barbarous mode, door is subjected to displacement with doorframe, be contained in door and the dry-reed tube switch of doorframe junction because of magnet away from and contact is changed, send warning initiating signal, lockhole switch is mainly the criminal for the pre-warning of not preventing, if think formal damage lock port lid, while entering house by cracking lockhole, to send out and displacement by the shift knob of lockhole cover plate (being also that early warning signal takes out sheet) lower compression, and send the signal of formal warning, because alarming starter has been connected on sound system, so when alarming starter has had after signal, sound system can start immediately and sends chimes of doom.

Four, the principle of sound system is: by a triode, formed the prestage that sound equipment amplifies, by a PNP triode 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 measure 1, implemented wireless remotecontrol radiating circuit, the distance of its transmitting is that sensitivity and weather have a significant impact, and the present invention is very high to the requirement of sensitivity, if by traditional method for designing, very difficult assurance meets designing requirement of the present invention, its reason is, position and distance that general transmitting can Iterim Change transmitting can receive that signal just could as long as can meet at that time reception.And transmitting of the present invention and receiving position are definite, in use procedure, can not change because of the difference of weather, (can affect like that normal life is breezy is used to), once at bad weather temporarily, just be difficult to guarantee the performance of product, so essential, increase necessary measure.And the present invention can largely improve sensitivity, the copper foil antenna and the increase external antenna that are specific a kind of English lower case n shape improve sensitivity, but increase external antenna, must do certain processing to radiating circuit, so just can reach best effect.The first must increase an electric capacity, isolates with antenna.It two is that this electric capacity must be welded in a special position, this position must be to be one end of high-frequency emission pipe collector at the antenna Copper Foil output at printed panel, and can not be in other place, this external antenna can adopt printed panel to be cut into rectangular-shaped and size, its benefit is, the reception having had, is also convenient to install.

Six, in information processor, have two kinds of electronic circuits, a kind of is radio reception circuit, and the wireless remotecontrol that its energy reliable reception sends from user transmits; 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.

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.

People's hand contact lockhole cap once there be the heart of crime, will send neutral warning language, immediately because this early warning also has distance from forcing open the door very much, so criminal is still had to very large deterrent effect.

2, having people to want to enter room by barbarous mode, door is separated with doorframe, and alarming starter also can promote sound system, sends warning.

3, do not affect neighbours's relation, do not injure person unintentionally, energy science is processed the relation of " having a mind to " and " being not intended to " behavior.

4, do not lose the due function of common alarm.

5, lockhole switch, does not need artificial additional move, and (as opened the door at every turn, closing involution behind the door), does not affect the normal habits and customs of people, thus do not affect the each starting of security system normal operation.

6, 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.

7, pre-warning circuit has very high sensitivity and reliability, after debugging, is all applicable to all-environment needs, and circuit is simple, and debugging is convenient.

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

9, the utilization of wireless remotecontrol radiating circuit, has improved remote-control sensitivity, makes launching effect better.

10, when nil case occurs, the telephone in message handler can be used as common communication telephones.
