2, 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, the explanation of signal shaping amplifier:
Be made up of preposition amplifying triode (02 in Fig. 1), phase inverter, control triode (08 in Fig. 1), driving relay (09 in Fig. 1), wherein phase inverter is made up of first order phase inverter (03) and second level phase inverter (06).
1, reliable trigger.Preposition amplifying triode is large power triode, employing is penetrated with output form, there is very strong feedback character, current base stage of putting amplifying triode has faint signal, it is the touch signal producing after hand contact lockhole cover plate, the output signal of preposition amplifying triode passes to phase inverter, phase inverter is converted to non-type touch signal 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.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, each phase inverter has been joined a sensitivity adjustment resistance, i.e. 05 in Fig. 1 and 07, its sensitivity resistor resistance is large, sensitivity step-down, resistance is little, and sensitivity raises, and has very strong adjustable.
3, drive the constant open contact of relay (09 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, being arranged on the lockhole switch on lockhole under lockhole cover plate is a key in the present invention, 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: amplifier tube (302 in Fig. 3) is a triode, form complementary circuit by a PNP triode (304 in Fig. 3) and NPN triode (305 in Fig. 3) audio frequency has been carried out to power amplifier, in the time having pre-alarm signal or lockhole switch to have warning enabling signal, open the power supply of warning circuit, so there are voice to produce, due to this electric circuit constitute is an OTL circuit, instead of OCL circuit, so debugging is simple, and there is element not perishable, the advantage higher with efficiency, voice sheet (301 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 make the dislike haveing nothing to do.
After the invention process, promoted the security performance of anti-theft safety door, outstanding advantage is as follows:
1, promote all sidedly security personnel's performance of anti-theft safety door, stranger can have been kept outside of the door at ordinary times, when someone commits 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, 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, 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.
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.
