For having a clear understanding of the meaning of the technical program, first will make the following instructions:
The existing achievement technology of inventor is that normal door no longer needs mechanical key, but open the door with electronics telecontrol engineering, thus lockhole can be covered, but also remain the mode of mechanical key enabling simultaneously, can also open the door with mechanical key if electronic telecontrol is opened the door when there is problem.If stranger wants to enter house by cracking lockhole, hand has just contacted lockhole cover plate will produce warning, and oneself because electronic telecontrol goes wrong by the situation that mechanical key opens the door, although warning also can be produced, because one of own side is on the scene, so can not feel alarmed.Also therefore identification circuit can differentiate that to open the door be that the normal door of owner or the preparation of perpetrator crack lockhole and enter room automatically.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is explained as follows further:
One, the explanation of pre-warning:
The signal amplification circuit be made up of enlarge leadingly triode (02 in Fig. 1), phase inverter, control triode (08 in Fig. 1), driving relay (09 in Fig. 1), the touch signal produced after hand being touched lockhole cover plate carries out shaping amplification, be converted into the available signal of telecommunication, and then start on-the-spot warning circuit, form early warning, wherein phase inverter is made up of first order phase inverter (03 in Fig. 1) and second level phase inverter (06 in Fig. 1).
1, reliable trigger.Enlarge leadingly triode is large power triode, employing is penetrated with output form, there is very strong Feedback polarity, when the base stage of enlarge leadingly triode has faint signal, namely the touch signal produced after hand contact lockhole cover plate, the output signal of enlarge leadingly triode passes to phase inverter, the voltage that non-type touch signal is converted to standard by phase inverter exports, and then trigging control triode, start and drive relay, drive relay adhesive, drive relay adhesive contact change and start acoustics circuit, and then produce warning.
2, pre-warning is produced reliable in time.Phase inverter quiescent dissipation is extremely low, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, so when there being triggering signal, pre-warning triggers reliable in time.The sensitivity of phase inverter adjusts very well, and a sensitivity adjustment resistance joined by each phase inverter, i.e. 05 in Fig. 1 and 07, and its sensitivity resistor resistance is large, sensitivity step-down, and resistance is little, and sensitivity raises, and has very strong adjustable.
3, the constant open contact of relay (09 in Fig. 1) is driven to connect power supply, normal pin contact, as output, drives the application of relay, enhances the reliability triggering late-class circuit (being on-the-spot warning circuit) here, small area analysis can be converted to big current by it, triggers late-class circuit more reliable and more stable.
4, further protection is: warn pre-the criminal failing to prevent; if think that further cracking lockhole enters room; just open lockhole cover plate; lockhole switch by the compressing of lockhole cover plate makes shift knob there occurs displacement because of loosening of lockhole cover plate; start warning system, thus send formal warning enabling signal.
Two, formal principle of reporting to the police: be fail to prevent for early warning, or whether crack lockhole crime and design.
Fail to prevent in pre-warning, when continuing to crack lockhole, the button being arranged on the lockhole switch under lockhole cover plate on lockhole, no longer by the compressing of lockhole cover plate, makes contact create change, thus is formed to report to the police and start.
Commit a crime if not by lockhole, but force open the door by other barbarous mode, as door backs down by jack by force, or with noise reduction cutting machine, lock is separated with door, only in right and wrong enabling under normal circumstances, door can start warning immediately with the door switch that doorframe is installed in conjunction with place, and door switch is magnetic switch, is made up of magnet-sensitive switch and magnet segment, the coverage of magnet and magnet-sensitive switch only has 3 centimetres, exceeded this virtual value, magnet-sensitive switch contact can change, thus forms startup of reporting to the police.
Door switch and lockhole switch are arranged on two different place's key places respectively, are to form the key of reporting to the police and starting, and make warning more fair and sensible, it shows: 1, can not produce wrong report.When house owner people stays out, the enabling now produced is not normal door, must be crime behavior, and warning is now very crucial, and when owner oneself is opened the door by lockhole with key, because oneself is on the scene, therefore can not make us terrified.
2, be very reliable, the normal life custom of people is affected not, in normal enabling is closed the door, lockhole switch can not action, thus lockhole switch can not damage, and door switch is because have correct electronic recognition signal in normal door situation, so in each normal door situation, need magnet segment and magnet-sensitive switch away from, but can not warning be produced, and open the door and close the door and also do not need artificial additional move, do not affect the normal habits and customs of people, thus do not affect the normal work that security system starts at every turn.
3, be that lockhole switch and door switch are reliably sensitive, just report to the police when crime behavior is not accomplished, thus loss is reduced to minimum.Because when lockhole cover plate loosens, lockhole switch contact will change and send warning enabling signal, the enabling under abnormal condition, door and the firm displacement of doorframe, namely magnet segment is just separated with magnet-sensitive switch, and magnet-sensitive switch sends warning enabling signal immediately.
Three, the explanation of on-the-spot warning circuit: amplifier tube (302 in Fig. 4) is a triode, constitute complementary circuit by a PNP triode (304 in Fig. 4) and NPN triode (305 in Fig. 4) and power amplifier is carried out to audio frequency, when having pre-alarm signal or lockhole switch to have warning enabling signal, open the power supply of on-the-spot warning circuit, so there are voice to produce, what form due to this circuit is an OTL circuit, instead of OCL circuit, so debugging is simple, and have element not perishable, the advantage higher with efficiency, voice sheet (301 in Fig. 4) can record some language in advance, as " please not stopping at this " or " asking speed to be left " etc., and don't the dislike that has nothing to do can be made.
Four, remote annunciator be in family nobody time there occurs event and the protection played, make people learn thing in family outside, allowing security personnel not start a leak.
1, in technical scheme 1, implement multi-code transmitter circuit arrangement, have important meaning, key benefit not easily produces malfunction.Be a very serious thing owing to producing telephone call, if wrong report, unnecessary terrified by causing, consequence is very serious.And use now the apparatus of remote control many, as locking of protecting car door, with unblock etc., all want straighforward operation, just define possible interference source.And adopt many yards just can thoroughly stop this kind of artificial disturbance afterwards.Otherwise after having had multi-code transmitter circuit, if there is alarm call must be non-normal door, so substantially increase the confidence level of the present invention's warning.Its principle that this circuit realizes multi-code transmitter is; When the first end launching programme control circut exports high-order, the not gate connected exports and makes the chip select end of this encoding block connected be low, institute's this chip select work, and remaining chip select does not work.When second exports as time high, in like manner only has corresponding chip select work.3rd piece, the 4th piece of reason is the same.Due to each coding integrated circuit with or door mode be input to modulating tube, so form the form of multi-code transmitter.
2, telephone alarm by telephone, receive programme control circut, interface circuit, form with radio receiver circuit, a few part dresses up one jointly, be arranged in telephone, its reason is this few part is several parts be closely related, be convenient to receive the signal sent by multi-code transmitter circuit, notify party.Its another reason is that the present invention can realize a tractor serves several purposes, namely can make communication telephones, can realize again relief logical.
In the common communication phone in market, general all have a number storage function, what telephone designed the argument of this function is easy to use with the telephone number often put through, its reason is if in advance by after often dialling storage key that plane No. code is stored in telephone, put through often dial time, the mode that multiple key could transfer to the code of long number should be dialled, become and only press the simple and direct form that a key just can transfer to multidigit number, thus use very convenient, because there is such characteristic, thus create important prerequisite for receiving unit implementing measure of the present invention, utilize this characteristic, in advance in phone, store the telephone number of related personnel.
After the invention process, improve the security performance of anti-theft safety door, outstanding advantage is as follows:
One, machinery and electronics perfect adaptation; anti-theft safety door is possessed early warning, formal advantage of reporting to the police; usually both people can be kept outside the door; run into other people when committing a crime, can warning in advance, can formally report to the police again; to " initiatively the protectiveness " that increase anti-theft safety door; be all very significant, so this product finishes the situation of the passive defence of anti-theft safety door completely, improve security personnel's performance of anti-theft safety door all sidedly.
Two, warning function is reliably outstanding, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, highly sensitive, reliable trigger.Attempt when there being people to destroy lockhole crime, just contact lockhole cover plate, early warning type system starts immediately, strengthens the psychological pressure of perpetrator.
Three, startup of reporting to the police is reliably sensitive, shows:
(1), warning system can not be reported by mistake.Because after coordinating with existing achievement, there is automatic recognition property.The enabling produced when owner is absent from the scene may be only crime behavior.Otherwise behavior of not committing a crime, lockhole switch and door switch can not send signal, this is the intrinsic property due to lockhole switch, with caused by the magnetic control character of door switch, when lockhole shift knob is being subject to oppressing and the change that contact occurs inherently to occur when not suffering oppression.And when the distance of magnet segment distance magnet-sensitive switch can make the contact of magnet-sensitive switch change.When without crime behavior, the button of lockhole switch is subject to the compressing of lockhole cover plate, thus lockhole switch contact can not change, and enabling is not under normal circumstances because there being correct identification signal, so door switch can not start warning, and when there being crime behavior, lockhole cover plate souththern pine moves, the button of lockhole switch is no longer by the compressing of lockhole cover plate, thus the contact of lockhole switch there occurs change, thus starts warning, but not enabling under normal circumstances, because magnet segment is separated with magnet-sensitive switch, therefore magnet-sensitive switch contact there occurs change and starts warning.
(2), easy to use, dependable performance, protection is tight, and two switches do not affect normal habits and customs after installing completely, and when without event, switch is standby, the initiative alarming when event occurs.
Four, stop the upper various electrical equipment interference existed of society, make tele-alarm more reliably credible.
Five, advanced in performance, irrelevant with people place distance, notification great efforts, can store multi-section phone, send out mass-sending simultaneously, such benefit can carry out Advise By Wire to multiple personnel, telephone can, as warning device, general time, be exactly common communication telephones when there is something special.
