3, the dialing integrated circuit is WE9142.

4, feedback capacity is electrodeless electric capacity in the timing feedback circuit.

5, feedback diode is face fit type diode in the timing feedback circuit.

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 propulsion system 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 normally behavior of opening the door is to open the door with electronic technology, rather than opens the door with mechanical key.When normal method was used electronic open-door, the identification circuit input had electronic signal, and the input of crime behavior identification circuit will start warning system without electronic signal.

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

The switch of one, 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, warning of the present invention having been accomplished more scientific, also is 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 usefulness ' key ' that is absent from the scene of owner is opened the door by lockhole within doors, is the crime behavior, and the warning of this moment 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 affect the normal habits and customs of people, thereby do not affect the normal operation of the each starting of security system.

The 3rd, protection is tight, no matter is to force open the door or the perpetrator wants by cracking lockhole the ABC ofly with barbarous mode, all can produce warning.

The 4th, the warning starting 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.

Two,Be positioned on the warning starting in the door, telephone call adopts wireless remote control to contact with being placed within doors, so telephone call is laid a little arbitrarily, has strengthened confidentiality.

Three, dialing integrated circuit chip among the present invention in the information processing part is following function, the one, can store a plurality of telephone numbers, in the situation that oneself stores complete in advance, (the present invention can utilize former existing phone that this integrated circuit is stored), as long as being stored pin, it adds a trigger pip, this sheet will automatically be controlled and send a phone number dial, so its a plurality of storage number ends have been connected on respectively on a plurality of output terminals in the sequential circuit cell, the dialing output terminal of this integrated circuit has been connected on the telephone set, so when the starting telephone call, the multi-section telephone number that a plurality of output terminals of 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 the number, so telephone alarm function is very powerful.

Four, the program circuit in this unit can be made of a variety of circuits, and the Copper Foil that the Hands-free key of the telephone set in its first output terminal and this part is corresponding links to each other, other output respectively with the dialing integrated circuit in multidigit store pin and link to each other.The program control rule that forms is that the high-order Hands-free key of opening base is at first exported in the first output, produces the off-hook program, triggers the first storage number pin in the dialing integrated circuit chip again; Call out the conversation of First receiver; Such as method repeatedly, can call out all receiver numbers that this sheet is stored.

Five, since adopted in the technical scheme one report to the police to start, the two-part closely combination of telephone call, just formed such defence program and protection philosophy, when normal the anti-theft security door knob other people keep outside the door.When having the people to force open the door by barbarous mode, when door separates with doorframe, the travel switch contact that is loaded on door and doorframe junction changes and produces alerting signal; When committing a crime by lockhole, in case open lockhole cap, the lockhole switch that is loaded between locking closure and the door can be because becoming non-oppression state from oppression state, and the normally closed contact of lockhole switch will become the signalling state; 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 antitheft 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.

Six, the timing feedback circuit has played vital role 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 forms 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, the feedback branch Capacitance derivative is full of electricity, 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 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 had the action that cracks lockhole, the warning initiating signal was sent in the action of lockhole protection switch, starts immediately the radio remote-controlled circuit starting, allows within doors telephone set 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 being security personnel's products, its wireless remote control all is to adopt the multi-code transmitter circuit, 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 remote control 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, the second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of the second pipe is fed back the charging of feedback capacity differential, until differential finishes.Second aspect is that the rejuvenation 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 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, satisfies fully the necessary preparation of feedback next time.

3, feedback capacity is little has formed charging rate altogether with feedback resistance, adjustable flexibly, is adapted to dissimilar switch.

4, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is larger, 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, sometimes be difficult for looking for, and price is higher, so proposed 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 the first pipe, not produce loss of signal branch road to positive feedback branch.

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; 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 suppress the crime behavior generation; and whether waiting for passively its destruction) 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.

2, 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 starting 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 is being subject to oppressing the variation that the contact occurs to occur when not suffering oppression.

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 preliminary work, the 2nd, the malfunctioning chance of mechanical switch is far superior to electronic component.

The 3rd, easy to use.Do not affect normal habits and customs after the installation fully.If increased trouble with former life, the shortcoming of obviously bringing to the people is or is to use inconvenience, or forgotten necessary operation and bring the malfunction of warning or malfunctioning.

The 4th, on-the-spot and two kinds of warnings of phone are arranged, deterrent force is larger, and is used because both complementations respectively have.

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

One of be the warning great efforts, can store the multi-section phone, simultaneously mass-sending, 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 again the fixed line phone in relevant place, 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 only have 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 set unification, can save many circuit, such 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 that 1 machine is multiplex, the telephone set after the repacking namely is a kind of telephone alarm, but still has kept all properties of telephone set, still can be used as communication telephones, such largest benefit is that family does not have too much device ornaments and to affect family attractive in appearance.

4, use the timing feedback, relaxed the requirement to switch, improved sensitivity and the reliability of the starting of reporting to the police.
