2, integrated amplifier phase inverter is COMS phase inverter.
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, thereby lockhole can be covered, but also retained the mode that mechanical key opens the door simultaneously, if opening the door, electronic telecontrol can also open the door with mechanical key while having there is problem.If stranger wants to enter house by cracking lockhole, hand rigidly connects and touches lockhole cover plate and will produce warning, and own to the electronic telecontrol situation of opening the door with mechanical key that goes wrong, although also can produce warning, on the scene because of one of own side, so can not feel alarmed.Also therefore identification circuit can automatically be differentiated the owner's that opens the door normal door or perpetrator's preparation and cracks lockhole and enter room.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is further explained as follows:
One, warn in advance the utilization of integrated amplifier and phase inverter in amplifying circuit, strengthened amplification effect, improved load-carrying ability, make pre-warning more accurately and reliably.
Be made up of integrated amplifier (3 in Fig. 1), phase inverter, control triode (13 in Fig. 1), driving relay (17 in Fig. 1), wherein phase inverter is made up of first order phase inverter (8) and second level phase inverter (12).
1, reliable trigger.The lead-in wire of lockhole cover plate has connected the normal phase input end of integrated amplifier, the multiplication factor of integrated amplifier is more much bigger than the multiplication factor of discrete component, therefore when hand contact lockhole cover plate has had touch signal, its signal is through the amplification of integrated circuit, pass through again the shaping of phase inverter, non-type touch signal is converted to the Voltage-output of standard, and then trigger and control triode, start and drive relay, drive relay adhesive, drive relay adhesive contact to change and start acoustics circuit, and then producing warning.
2, produce pre-warning in time reliably.The fine adjustment of sensitivity of integrated amplifier, sensitivity adjustment resistance (2 in Fig. 1) resistance of integrated amplifier is large, its sensitivity step-down, resistance is little, and sensitivity raises, and has very strong adjustable, compared with the amplifying circuit of discrete component, circuit is simpler, adjusts more conveniently, and performance is stronger.Phase inverter quiescent dissipation is extremely low, when input signal changes, can automatic fitration reconcile, so the voltage of output can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, so in the time having had triggering signal, pre-warning triggers reliable in time.The fine adjustment of sensitivity of phase inverter, every grade of phase inverter has all been joined a sensitivity adjustment resistance, i.e. and 6 in Fig. 1 and 7, has very strong adjustable.
3, drive the constant open contact of relay (17 in Fig. 1) to connect power supply, normal pin contact, as output, drives the application of relay, has strengthened the reliability of triggering late-class circuit (being warning circuit) here, it can be large electric current by little current conversion, triggers late-class circuit more reliable and more stable.
4, further protection is: fail in pre-warning the criminal who prevents; if think that further cracking lockhole enters room; just open lockhole cover plate; be subject to the lockhole switch of lockhole cover plate compressing to make shift knob that displacement occur because of becoming flexible of lockhole cover plate; start warning system, thereby sent formal warning enabling signal.
Two, lockhole switch, is arranged under lockhole cover plate on lockhole, is a crucial existence, exactly because there has been lockhole switch, just makes warning of the present invention accomplish more scientific, is also the place different from a lot of alarms, and its reason is:
1, can not produce wrong report.When house owner people stays out, what now produce opens the door, and is not normal door, opening the door if now crack lockhole, must be crime behavior, and warning is now very crucial, open the door by lockhole with key and work as owner oneself, because own on the scene, therefore can not make us terrified.
2, be very reliable, on people's normal life custom impact not, in opening the door normally and closing the door, lockhole switch can not move, thereby lockhole switch can not damage, do not need artificial additional move and open the door to close the door, do not affect the normal habits and customs of people, thereby do not affect the each normal work starting of security system yet.
3, be that lockhole switch is sensitive reliable, in the time that crime behavior is not accomplished, just report to the police, thereby loss is reduced to minimum.Because in the time that lockhole cover plate is loosening, lockhole switch contact will change and send warning enabling signal.
Three, the explanation of warning circuit: with audio-frequency power amplifier, simple in circuits, quiescent dissipation is low, operating voltage range is wide, and peripheral cell is few, and voltage gain adjustment degree is wide, to advantages such as the distortion factor of sound are low, voice sheet (201 in Fig. 3) can be recorded some language in advance, as " please not stopping at this " or " asking speed to be left " etc., and don't can cause irrelevant dislike.
After the invention process, promoted the security performance of anti-theft safety door, outstanding advantage is as follows:
1, machinery combine with electronic circuit, General Promotion the security performance of anti-theft safety door, in the time having people to commit a crime, can give warning in advance, can formally produce again warning, the situation of the passive defence of anti-theft safety door in the past that is through with completely.
2, warning function is outstanding reliable, and integrated amplifier amplifying power is strong, and when input signal changes, the automatic fitration of phase inverter energy is reconciled, the voltage of output can be protected, and antijamming capability is strong, promotes load-carrying ability, reduce time delay, highly sensitive, reliable trigger.When there being people to attempt to destroy lockhole crime, rigidly connect and touch lockhole cover plate, early warning type system starts immediately, strengthens perpetrator's psychological pressure, will commit a crime and prevent before starting.
3, warning startup is sensitive reliable, shows:
(1), warning system can not be reported by mistake.Because after coordinating with existing achievement, there is automatic recognition property.What when owner is absent from the scene, produce opens the door, and may be only crime behavior.Otherwise the behavior of not committing a crime, lockhole switch can not send signal, and this is the intrinsic property due to lockhole switch, and the variation of contact occurs to occur in the time that lockhole shift knob is being subject to compressing and is not suffering oppression.When without crime behavior, the button of lockhole switch is subject to the compressing of lockhole cover plate, thereby lockhole switch contact can not change, and in the time having crime behavior, lockhole cover plate souththern pine is moving, the button of lockhole switch is no longer subject to the compressing of lockhole cover plate, thereby variation has occurred in the contact of lockhole switch, reports to the police thereby start.
(2), easy to use, dependable performance, protection is tight, lockhole switch does not affect normal habits and customs after installing completely, when without event, lockhole switch is standby, initiative alarming in the time that event occurs.
4, simple in circuits is easily produced, and no matter is to warn in advance amplifying circuit or warning circuit, and peripheral element is all little, and debugging is convenient.
