3, when after door and doorframe closure, the button of door switch is subject to the compressing of doorframe.
To each technical measures of the present invention, be explained as follows:
One, the present invention is the theft-proof monitor with multiple warning.
The firstth, pre-warning: according to the existing achievement technology of inventor, normal door is to open the door with opening door of remote-control or phone, do not need mechanical key, therefore lockhole is covered, but retain the mode that mechanical key opens the door, if remote control or phone have occurred problem and can also open the door also therefore possessed recognition capability, can reliable recognition go out oneself open the door or commit a crime and open the door.Stranger wants to enter house by cracking lockhole, hand rigidly connects tactile pilferproof closure and just produces touch signal, alarm function effect unit is sent pre-warning immediately, the sound can send " please noting ", or the language such as " please not staying at this " is prevented, can cause very large psychological pressure to possibility criminal by the benefit of gender neutral language, but can not damage being not intended to person, more can not cause in terror neighbours, the generation of pre-warning can make him know clearly, in room, early there is preparation, if continued, must there is " below " waiting for, by have thereby hint obliquely at later difficult, probably impel it to stop as early as possible, halt at this point, so played the initiatively effect of protection.
The secondth, warning device, i.e. lock-switch and door switch.Lock-switch is: if pre-warning fails to prevent, destroy pilferproof closure, because the button of lock-switch is subject to the compressing of pilferproof closure, if pilferproof closure is loosening, lock-switch contact must change, and sends various functional effect warnings thereby start alarm function effect unit; Door switch is: door switch is arranged on door and doorframe junction, when after door and doorframe closure, doorframe is oppressed the button of door switch, if forced open the door by barbarous mode, when door and doorframe are subjected to displacement, the contact of door switch is no longer subject to the compressing of doorframe and contact is changed, and opens various functional effects and start alarm function effect unit.
The 3rd is the various functional effects in effect warning unit, not only has onsite alarming, also has photorecorder shooting record.
Two, signal amplifies the explanation of shooting with video-corder control circuit (Fig. 1):
Signal amplifies shoots with video-corder control circuit, can, by faint touch signal, amplify and be converted into the available signal of telecommunication, thereby start alarm function effect unit, at the beginning of crime, just sends pre-warning.
1, there is good function, in the time just having crime behavior, just can give warning in advance and show: enter room when crime personnel prepare to crack lockhole, due to the existing achievement technology of inventor, lockhole is covered, the pilferproof closure (06 in Fig. 1) that must first open coverage lockhole just can crack lockhole, and in the time that crime personnel's hand has just touched pilferproof closure, just produced touch signal, and amplify the amplification of shooting with video-corder control circuit through signal, start the effect function of rear class.
In Fig. 1 011 a kind ofly has the time to control with the instrument showing is time controller, as long as preset the time, it will output signal, through shooting with video-corder or (in Fig. 1 016) after, open electronic switch (in Fig. 1 019), then allow video camera work.
2, pilferproof closure is sensitive reliable: touch signal has been taked AC signal, add strengthening touch signal, the increase of this product communication channel, so improved widely the sensitivity of touch signal, this is the first feature, and the second feature is that communication channel designs in the low-pressure secondary side of transformer in order to ensure safety, low-pressure secondary side is far below human safety voltage, so can not produce unsafe conditions.Thereby become all very high forms of the high and touch sensitivity of a kind of degree of safety.
3, circuit is reliable, product has good performance, as long as there is crime behavior, hand rigidly connects tactile pilferproof closure (06 in Fig. 1) just can produce touch signal, touch signal has adopted two-stage to penetrate with isolation amplification, highly sensitive, and voltage amplifying tube (012 in Fig. 1) afterwards and power tube (014 in Fig. 1) have adopted the complementary type amplification of NPN triode and PNP triode, gain high, carrying load ability is strong, can reliably start various functional effect (as: video cameras, camera, alarm etc.), thereby touch dependable performance, that is to say that pre-warning can be reliable.Even touch signal is very faint, penetrate with after amplifying through two-stage, then carry out voltage amplification and power amplification, more reliable, and this circuit does not need debugging substantially, and also triode is not fragile.
4, Design of Amplification Circuit has sensitivity adjustable resistance (013 in Fig. 1), is convenient to batch production.
Two, produce shooting and record the principle of overall process: although crack hand after lockhole and left the pilferproof closure of lockhole top, but the lockhole shift knob being pressed under pilferproof closure is oppressed by pilferproof closure no longer, there is variation, lock-switch (021 in Fig. 1) is closed, so opened video camera logging.
If cruelty forces open the door, when door and doorframe are subjected to displacement, the contact of door switch is no longer subject to the compressing of doorframe and contact is changed, so opened video camera logging.
Before generation case, after shooting record, there is displaying principle: in Fig. 1,018 is a kind of rest-set flip-flop with demonstration, thereby there is Memorability, shoot with video-corder or when door has output to open electronic switch (in Fig. 1 019) at every turn, 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.
The principle of shooting record writing time before generation case: shoot with video-corder at every turn or when door has output to open electronic switch, have signal to trigger time controller, so can automatically record the moment of generation.
Three, there is further protection; fail in pre-warning the criminal who prevents; if think that further cracking lockhole enters room; just open pilferproof closure; be subject to the lock-switch of pilferproof closure compressing to make lock-switch button that displacement occur because of becoming flexible of pilferproof closure; start warning system, thereby sent formal warning enabling signal.It is more scientific that the use of lock-switch has been accomplished warning of the present invention, because the installation site of lock-switch is under pilferproof closure on lockhole, pilferproof closure one is loosening, lock-switch button no longer suffers oppression, must change the contact of lock-switch, thereby produce warning enabling signal, and report to the police thereby start, opening warn functional effect unit.Lock-switch starts warning dependable performance, shows:
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, in opening the door normally and closing the door, lock-switch can not move, thereby lock-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 lock-switch is sensitive reliable, lock-switch can be travel switch, just reports to the police, thereby loss is reduced to minimum in the time that crime behavior is not accomplished.Because in the time that pilferproof closure is loosening, lock-switch contact will change and send warning enabling signal.
Four, there is the defencive function that barbarous mode is forced open the door.This is the effect because of door switch, and when after door and doorframe closure, doorframe is oppressed the button of door switch, under improper door opening state, and door and the firm displacement of doorframe, door switch contact will change and produce formal warning enabling signal.
Door switch can not produce warning enabling signal in the situation that of normal door, therefore can not affect people's habits and customs, without people's additional move, and be not to open the door normally yet, and door separates with doorframe is firm, and door switch can start immediately, sensitive and reliable.
Five, in alarm function effect unit, also have photorecorder, no matter be that to crack at the beginning of lockhole be that hand rigidly connects tactile pilferproof closure, still continuing to crack lockhole is that pilferproof closure souththern pine is moving, all can start photorecorder shooting record, so that people observe simultaneously.
The amplifier tube of onsite alarming circuit in alarm function effect unit (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 lock-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.
When only having, alarm function effect unit just starts, when without event, can be not fragile so can not start, and all standby at any time, once event occurs, start immediately effect unit and form various functional effects.
After the invention process, promoted the security performance of anti-theft safety door, outstanding advantage is as follows:
Anti-theft safety door has possessed " initiatively protection ", is stranger can 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, has promoted security personnel's performance of anti-theft safety door all sidedly.Show: 1, this good performance can embody in the following areas fully, the one, be not subject to the impact of floor, no matter be the ground floor joining with ground, or mezzanine, or there is good performance in a building.The 2nd, be not subject to the impact of weather.No matter be the night higher in humidity, or on lower daytime, or any season throughout the year, all thering is good performance, this is all very important for the product for the equipment class of ensuring public security, and is also very important prerequisite.Otherwise be directly connected to the reliability of security personnel's product.
2, can assurance function effect: reason one is that early warning circuit is made up of triode, and the required anti-phase operating voltage of triode is flexible, has very large space, (as a lot of integrated circuits, operating voltage is had to higher requirement) while therefore joining alternating current source, not fragile, also easily join.Can ensure that integrated form is shot with video-corder control circuit in the time having people to want to destroy lockhole will start immediately, and the 2nd, load capacity is strong thereby can ensure the embodiment of various alarming effects.
3, working power can adopt full-wave rectification, expanded can supporting power supply space.Full-wave circuit advantage is, can be less with two commutation diode, and commutation diode is easy failed part.
4, report to the police and start reliably, can not produce wrong report, because after coordinating with existing achievement, have automatic identification function, opening the door when owner is absent from the scene, must be crime behavior, as long as there has been crime behavior, lock-switch must send warning enabling signal, and this is because oppress when the button of lock-switch is subject to pilferproof closure, and has crime behavior, pilferproof closure souththern pine is moving, the button of lock-switch is no longer subject to the compressing of pilferproof closure, and the contact of lock-switch is bound to send variation, thereby produces warning enabling signal.And without crime when behavior, the button of lock-switch is the compressing that is subject to pilferproof closure, the contact of lock-switch can not change.Lock-switch does not affect people's normal life custom, lock-switch at any time in etc. life state, easy to use, protection is tight.
5, force open the door in the face of cruelty, still there is protectiveness.This is because there is door switch, door and doorframe displacement, and door switch button is no longer subject to the compressing of doorframe and contact is changed, and produces formal warning enabling signal.
6, tracing property is strong, at the beginning of crime, just produce pre-warning and shoot with video-corder, commit a crime as continued, can formally report to the police and shooting record, and alarm function effect unit just just starts in the time having the possibility of crime, tightly follow the step of crime, and in the time of normal door, alarm function effect unit can not be opened, so can not damage.
7, circuit is simple, easily produces.
8, cheap, easily universal.
