For having a clear understanding of the meaning of the technical program, first will make the following instructions:
According to the existing achievement technology of inventor, normal door does not need mechanical key, but with telecontrol engineering, therefore lockhole is covered, if crack lockhole, must first take off lockhole cover plate, and just produce touch signal in hand contact lockhole cover plate, and send pre-warning, will commit a crime and prevent before occurring, as further crime, more can produce formal warning, no matter continue to crack lockhole or cruelty enters room, alarming effect is not only on-the-spot warning, also possess the record of making a video recording before concluding a case, antitheft series products is obtained further perfect.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is further explained as follows:
The utility model is the antitheft series products that possesses multiple protective.
First heavily protection be pre-warning.The warning of just sending in hand contact lockhole cover plate, is called pre-warning, and warning now, from producing also distance very of consequence, has therefore increased perpetrator's psychological pressure to a great extent, probably allows perpetrator receive hand at this point, avoids the generation of consequence.
Second heavily protection be that the warning that lockhole switch produces starts.This fails to prevent for pre-warning and produces, and loosening when lockhole cover plate, lockhole switch is no longer subject to the compressing of lockhole cover plate and contact is changed, and has produced formal warning enabling signal.
Triple protection is that the warning that door switch produces starts.If perpetrator adopts the mode crack lockhole to commit a crime, but forces open the door by the mode of the cruelties such as jack, when door and the firm displacement of doorframe, travel switch is no longer subject to the compressing of doorframe and has produced formal warning and start.
Quadruple protection is that alarming effect is not only on-the-spot warning, has followed especially shooting record, records accurately the cause and effect that event produces, and the important informations such as time personage are convenient to understand the truth of event.
One, produce the principle of pre-warning, i.e. the explanation of control circuit before case:
Before case, control circuit is comprised of preposition integrated circuit, phase inverter, control triode, power discharging transistor.
1, multiplication factor is strong, reliable trigger.Preposition integrated circuit (3 in Fig. 1) is as prestage, element is few, reduce the bad probability of element, the touch signal producing when hand contact lockhole cover plate is after preposition integrated circuit one-level is amplified, through phase inverter secondary, shaping is amplified again, trigger and control triode (13 in Fig. 1), finally encourage the rear output of power discharging transistor (16 in Fig. 1), circuit is shot with video-corder in startup and on-the-spot warning circuit sends pre-warning.
2, the pre-warning of generation is sensitive reliable.Integrated circuit multiplication factor is high, compare with the amplifying circuit of discrete component, circuit is simpler, adjusts more convenient, performance is stronger, phase inverter can be converted to irregular touch signal the signal of telecommunication of standard, and then triggers and control triode, and control triode and power discharging transistor form form of tubes, as long as it is low to control the colelctor electrode of triode, the colelctor electrode of power discharging transistor is just high, substantially do not need debugging, and triode is not fragile.
3, shooting record performance is excellent, has to pay a return visit to save time, economize energy, saves device resource etc. serial advantage.
Shoot with video-corder rest-set flip-flop, the manual control switch composition of circuit or door start-up circuit, electronic switch, video camera, time controller, band demonstration.
In Fig. 2 20 is a kind of instruments that the time is controlled and show that have, i.e. time controller, as long as preset the time, it will output signal, through or door start-up circuit (17 in Fig. 2) after, open electronic switch (in Fig. 2 18), then allow video camera (19 in Fig. 2) work.
Produce the principle that overall process is recorded in shooting: although hand has left lockhole coverage sheet after forcing open the door, but the lockhole shift knob being pressed under lockhole coverage sheet is oppressed by lockhole coverage sheet no longer, there is variation, lockhole switch (27 in Fig. 2) is closed, so opened video camera (19 in Fig. 2) logging.
(1) before, generation case, after shooting record, there is displaying principle: in Fig. 2,21 is a kind of rest-set flip-flops with demonstration, thereby there is Memorability, when each or door has output to open electronic switch (in Fig. 2 18), the rest-set flip-flop that has memory is triggered in capital, once so after rest-set flip-flop is triggered, additional LED can luminescence display.
(2) principle of shooting record writing time before, generation case: when each or door start-up circuit has output to open electronic switch, there is signal to trigger time controller, so can automatically record the moment of generation, thereby each hand contact lockhole coverage sheet all can produce and shoot with video-corder and onsite alarming.
Two, for pre-warning, fail to prevent, or barbarous mode forces open the door, alarm switch can produce to report to the police and start.Exactly because there has been alarm switch, just make warning of the present invention accomplish more scientific, be also the place different from a lot of alarms, its reason is:
1, can not produce wrong report.When house owner people stays out, what now produce opens the door, and must not be normal door, if now crack lockhole, opening the door, must be crime behavior, and warning is now very crucial, and work as owner oneself, with key, by lockhole, open the door, because own on the scene, therefore can not make us terrified.Without forcing open the door under remote signal, be also crime behavior, reporting to the police, it is very crucial to start.And opening the door while having had correct remote signal, door switch can not produce to report to the police and start.
2, very reliable, standby at any time, because in opening the door normally and closing the door, lockhole switch can not move, thereby lockhole switch can not damage, and open the door to close the door, do not need artificial additional move yet, do not affect the normal habits and customs of people, thereby do not affect the each normal work starting of security system.
3, be that alarm switch is sensitive reliable, when crime behavior is not accomplished, just do not report to the police, thereby loss is reduced to minimum.Because when lockhole cover plate is loosening, lockhole switch contact will change and send warning enabling signal, and in without remote signal situation, door and the firm displacement of doorframe, the button of door switch no longer assign frame compressing and contact is changed, produce formal warning enabling signal.
Three, alarming effect is obvious, no matter be pre-warning, or alarm switch starts and the formal warning of generation, can start on-the-spot warning circuit and shoot with video-corder circuit, the record of making a video recording when reporting to the police.
All very strong tracing properties, and when nil case non-transformer, so circuit can not damage.In acoustics circuit, use audio-frequency power amplifier, simple in circuits, quiescent dissipation is low, and 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.
After the invention process, promoted the security performance of anti-theft safety door, outstanding advantage is as follows:
Promoted 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 warning again, the situation of the passive defence of anti-theft safety door in the past that is through with completely, is mainly manifested in following several respects:
1, warning function is outstanding reliable, highly sensitive, and the multiplication factor that circuit is shot with video-corder in touch is strong, 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.
2, shooting record performance is excellent.The one, before case, record is given prominence to the key points.The 2nd, after having record, can automatically show the owner of announcement, can " not leak visit ".The 3rd, there is to do cases and can record overall process.The 4th, shooting records various ways.The 5th, when recording, there is time of generation.The 6th, video camera is also not fragile, and these 6 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, has really realized workable feature and has been.(in the situation of work strain, family can not impunity carry out " returns visit " to shooting, more impossible in return visit, watch a lot of useless impunities general to record).Thereby for understanding family public security present situation, there is very important positive role.
3, warning startup is sensitive reliable, shows:
(1), there is automatic identification function, and at any time all in a kind of " highly waiting " state, protection is tight.
(2), easy to use, dependable performance, alarm switch does not affect normal habits and customs, initiative alarming when event occurs after installing completely.
4, circuit is simple, and debugging is convenient, is applicable to coordinating with door, improves security personnel's performance of anti-theft safety door.
