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, anti-theft safety door is to the stage of following progress: normal door is opened the door without mechanical key, but the mode of opening the door with electronics telecontrol engineering or phone, when opening the door, be installed on the power set in the door, will promote the lockset action.Meanwhile, kept the form that mechanical key opens the door, why like this, be automatic system a kind of the remedying that Shi Nengyou opens the door that go wrong.This namely is if open the door with mechanical key, is a kind of improper situation of opening the door.The generation of this mode may be two kinds of situations only, and a kind of situation is that system breaks down, and what owner was on the scene within doors oneself opens the door, and to be others enter house by the lockhole crime taking off lid a kind of situation, and this is to need to report to the police owner's the situation of announcement.

In the common communication phone in market, generally all have a number storage function, telephone design this function argument be to use easily the long-distance call card to make a long-distance call, to economize words money.Used method is, can use the storage button one in the keyboard, button two, store in advance respectively necessary two groups of multidigit passwords in the long-distance key, at this moment, when using long-distance card to make long-distance call, but only need by corresponding first group of required multidigit password of storage button one automatic poking card release, and needn't press out the corresponding a plurality of buttons of this group multidigit password fully bothersomely, in the time of should needing second group of password together, only need press store key two at this moment phone will can automatically transfer to again and play second group required multidigit password of long-distance call card, also needn't press out a plurality of buttons corresponding to multidigit password fully bothersomely.But the present invention has utilized this storage function of telephone just, change and store thinking, with originally being designed to store the two groups of used multidigit passwords of card of making a long-distance call, change the number that is stored as respectively two mobile phones into, thereby created important prerequisite for the invention process measure one.

The meaning of abovementioned technology, concrete condition further is explained as follows:

In the technical scheme of network alarming part of the present invention, in telephone, except having adopted measure one described technical scheme, two kinds of electronic circuits have also been increased.A kind of is the radio reception circuit, the radio signal that its can reliable reception sends in the anti-theft safety door, another part is a kind of electronic program circuit, and the logic function of this programme control circut is to contact by the lead-out wire of 5 groups of buttons in the measure one, the at first instantaneous Hands-free key of opening, then open and store button one key, behind the certain hour, close again Hands-free key, 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 the second key is stored, form the call dialing to second storage phone, such iterative cycles is until termination.

Radio reception circuit Main Function is the starting point of control electronic program circuit in the telephone, and in a single day he receive signal, just can send instruction, allows first programme control circut starting start working.

In the measure scheme one to processing and the installation of two switches, it is warning actuating section of the present invention, it also is a bright spot of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, make warning of the present invention accomplish science, also be the place different from a lot of alarms, major embodiment in the following areas:

The one, report to the police very correct, more can generation not make us terrified wrong report, this is the most important.When normal life is opened the door, because all be that electric device starts, and all can produce identification signal, all can not report to the police with electronics remote control thereof or phone door opening method.The situation that the hole top cover plate that uncages opens the door only has two kinds of situations: a kind of situation is that other people want the situation of entering house by cracking lockhole, and this also is necessary alarm condition, also is most applications, also is our desirable alarm condition.Next is that system breaks down, owner need to open the situation that locking closure opens the door with mechanical key, and this situation is owner's lower warning of knowing the inside story on the scene, not only is not to report by mistake, can also be this situation as at ordinary times to a kind of maintenance test of product, thereby this situation can be got rid of from wrong report.So the people has the situation of telephone call outside, draws attention, extremely be necessary because this must be to have the people taking off the lockhole cover plate, and do not have other reason.The 2nd, protection is tight, enters indoorly because crime coming round to move into one's husband's household upon marriage, and most cases is to cross the threshold after selecting to crack lockhole, but this method can be reported to the police.Three be two switches sensitive such as the korean pine lid, the contact of switch can change and reliable, if take off lid fully, it is certain that the contact changes, so be sensitive and reliably.

Owing to having adopted closely combination of two parts in the technical scheme one, just formed such guard mode and protection philosophy, when normal the anti-theft security door knob other people keep outside the door.And other people are when committing a crime with lockhole, in case open lockhole cap, the 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 switch will become connection by disconnection, the electronic circuit of its control produces two functions, a kind of function is to connect the alert acoustic-electric source that promotes, produce onsite alarming, caution is caused at the scene, and prior a kind of function is with the launch start of control expelling plate, after the network alarming in the measure of the present invention is partly received and transmitted, start immediately two mobile phones storing in the telephone and store number to outcall, the owner of notice mobile phone in time determines, with processing.Loss is reduced to minimum, or remedy.

Multi-code transmitter is adopted in wireless remote control emission in the scheme one, and important meaning is arranged in the present invention, and 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 now the apparatus of remote control many, such as locking that car door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the many yards artificial disturbances that just can thoroughly stop afterwards this class.After otherwise the multi-code transmitter circuit has been arranged, must be non-normal door if alarm call is arranged, so have greatly improved the confidence level that the present invention reports to the police.This circuit realizes that its principle of multi-code transmitter is; When the 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 of connected, this chip select work of institute, and remaining sheet is not worked.When the second end is output as when high, in like manner only has corresponding section's chip select work.The 3rd end, the 4th end reason is the same.Since each coding integrated circuit with or a door mode be input to modulating tube, so form the form of multi-code transmitter.

Electronic self-locking circuit has played important function in the present invention, its Main Function has 2 points, one of, relaxed the requirement to switch, namely switch can be key type, also can be button-type, and on the power of contact without impact, so can adopt miniaturely, the difficulty of installing to reduce switch increases the attractive in appearance of door simultaneously.Two be improved the starting of reporting to the police sensitivity and reliability.Its 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 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.Its reason two is that owing to being security personnel's products, its wireless remotecontrol 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.

Excellent performance of the present invention wherein also has the very important point, is exactly in the situation that cost is low, has good wireless remotecontrol receiving ability.The benefit that produces is if receiving ability is strong, the telephone of putting within doors after the innovation can be more random, can be placed on a very wide scope within doors, also can be placed on more hidden within doors place, and not be subjected to the impact of the things such as furniture, this both had been beneficial to the attractive in appearance of family, and be conducive to countersabotage, thereby very strong practicality is arranged, because after having adopted measure 3, the radio reception ability improves a lot.

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

1, after the invention process, anti-theft safety door not only original function does not change, and two kinds of alarm functions have been increased, on-the-spot alarm function wherein, can produce psychological pressure to the crime personnel, reduce the result, wherein the phone caution can be sent unsafe caution to house owner people, takes more strong anti-crime measure can make owner.So two kinds of alarm functions possesses, plant the security personnel's performance that has promoted all sidedly security door.

2, telephone call excellent performance.The first receives the mobile phone of telephone call because utilized the advanced network platform, and is incompetent in this locality, or in the other places, all can receive.After receiving the caution that mobile phone sends, incapability is for I, still authorizes other people to the scene, and positive meaning is arranged.It two is that the telephone alarm signal received of personnel is very timely outside, and service center is very wide.If the behavior of opening locking closure is arranged, contact switch will send the signal onsite alarming, and so the while telephone call is very timely.And because the telephone call of profit of the present invention has been used advanced communication network system, so very advanced, personnel can receive in this area as long as can both receive at network service area outside, still can receive in the other places, in time for prevention, remedy etc. all very beneficial.

3, sensitive alarm and reliable.First starting is sensitive and reliable, because the scientific structure of this part, newly-increased locking closure is contact switch compressing tightly at ordinary times, and contact switch can be reliably disconnects the constant close contact of contact, in case become flexible lockhole cap, produce displacement, contact switch can alleviate state because becoming from oppression state, and the constant close contact of switch will become connection by disconnection, and this is sensitive, if take off lid fully, the connection of constant close contact is very reliable.Its two telephone calls calling procedure is reliable, because the telephone call part in the measure one, in case starting can be called out by iterative cycles, the mobile phone holder can receive signal.

4, warning system is not reported by mistake basically.Reporting to the police if produce, may be two kinds of situations only, and a kind of situation is that system breaks down, and owner itself opens the door at the scene within doors, and owner is on the scene to be known, can be not alarmed.A kind of situation then is dangerous, is that others wants to crack the situation that anti-theft safety door is entered house and need to be proposed to warn to owner.

5, 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 be used as communication telephones, and family does not have too much ornaments and affects attractive in appearance.

6, easy to use, some are used for the alarm product of door protection the first, open the door at every turn or close the door and all need the action of once involution after finishing, obviously very numerous and diverse, and this does not brightly need at ordinary times, only taking off when covering, just produces an involution, and during this situation seldom, so do not affect normal life between the operating period fully; It two is that involution was easy after lockhole cap was taken off lid.

7, be easy to produce, can utilize a lot of circuit parts in the telephone, relatively simple.

8, objectively increased the aesthetic property of door, because do not show lockhole, assumed an entirely new aspect, do not occurred lockhole simultaneously, refreshing close, also to a certain degree avoided simultaneously bringing out by the lockhole crime may.

9, can improve greatly ability without electric receiving unit behind the implementing measure 3, like this telephone call put a very wide scope can relaxing in doors, can be placed on more hidden within doors place, be not subjected to the impact of the things such as furniture, strengthened the countersabotage ability.

10, stopped social upper electronic interferences when going to lock such as automobile fully, made warning more credible reliably.
