For having a clear understanding of the meaning of the technical program, first will make the following instructions:
The existing achievement technology of inventor; normal door is without mechanical key; but with telecontrol engineering; therefore the lockhole on anti-theft safety door is covered, and does not reveal at ordinary times lockhole, and this becomes the measure of a protection; but retain the mode that mechanical key opens the door; once remote control is malfunctioning, can also opens the door, instead of cannot enter house.
The present invention is security personnel's monitor a kind of and that door is supporting, the function that it produces is at the beginning of event occurs, just to produce pre-warning, and pre-warning fails to prevent no matter continue to crack lockhole or cruelty is forced open the door, can formally report to the police, in warning, also comprise shooting record, lower time of accurate recording and process, to check.
Because only just start video recorder and warning in generation event, therefore can not damage and can not waste resource yet.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is further explained as follows:
One, pre-warning produces principle and effect:
1,, in the time of no touch signal, when hand does not contact lockhole cap, the bridge circuit of four electric capacity (7 in Fig. 1,8,9, the 10) composition in electric bridge does not have output and exists, thereby the preposition unit of bridge type no-output; In the time having touch signal, while being hand contact lockhole cap, bridge circuit parameter changes, be the output that has had alternating current, again through after four diodes are bridge rectifier (11 in Fig. 1), become direct current output, triggering sound warning unit after by two-stage integrated amplifier, signal being amplified, produces warning in advance.
2, simple in circuits, integrated amplifier is outstanding reliable:
(1), bridge type amplifying unit amplification effect is good, dependable performance: its reason is in the time of no touch signal, four electric capacity (7 in Fig. 1,8,9,10) parameter in electric bridge is consistent, internal current balance, thereby the preposition unit of bridge type no-output, and when after hand contact lockhole cap, there is touch signal, lockhole cap has connected commissure electric capacity (6 in Fig. 1) parameter serious variation has occurred, so there is signal output the preposition unit of bridge type, highly sensitive, circuit is reliable and stable, for integrated amplifying unit has been established fine basis.
(2), in integrated amplifying unit, there is two-stage to amplify, once the preposition unit of bridge type signal output, first order integrated amplifier is worked immediately, signal after amplifying is for the first time transferred in the integrated amplifier of the second level, and the signal after amplifying for the second time can start later circuit more reliably; Sensitivity adjustment resistance in circuit can be adjusted the sensitivity of integrated amplifier easily.Use integrated circuit to make amplifier, its benefit is that element is few, reduces the probability of component wear, and simple in circuits is easily produced.
3, video recorder is tightly followed warning and is produced, and can not produce useless record.
In Fig. 1 23 is a kind of instruments that have time control and show, i.e. time controller, as long as preset the time, it will output signal, through startup or door (21 in Fig. 1) after, open electronic switch (in Fig. 1 24), then allow photorecorder (25 in Fig. 1) work.
Produce the principle that overall process is recorded in shooting: although hand has left lockhole cap after forcing open the door, but the lockhole shift knob being pressed under lockhole cap is oppressed by lockhole cap no longer, variation has occurred, and lockhole switch (20 in Fig. 1) is closed, so opened photorecorder logging.
(1) before, generation case, after shooting record, there is displaying principle: in Fig. 1,26 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. 1 24), 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: shoot with video-corder at every turn and control or when door 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 cap all can produce and shoots with video-corder and onsite alarming circuit.
Two, alarm switch is made up of lockhole switch and door switch, door switch is magnetic switch, the intersubjective coverage of the magnet of magnetic switch and magnetic switch only has 1.5cm, therefore, if not normal door, door has only had displacement with doorframe and has exceeded the distance of 1.5cm, and magnetic switch moves immediately, starts warning.
Lockhole switch is arranged on lockhole cap below, and lockhole cap is oppressed the button of lockhole switch, and therefore loosening when lockhole cap, lockhole switch moves immediately, starts and reports to the police.
1, can not produce wrong report.When house owner people stays out, what now produce opens the door, and is not normal door, if crack that lockhole opens the door or force open the door by barbarous mode, warning is now very crucial, and opens the door by lockhole with key as owner oneself, because own on the scene, therefore can not make us terrified.
2, alarm switch is very reliable, standby at any time, in opening the door normally and closing the door, alarm switch can not move, thereby alarm 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 alarm switch is sensitive reliable, in the time that crime behavior is not accomplished, just report to the police, thereby loss is reduced to minimum.
Four, warning circuit has very strong tracing property, and in the time of nil case non-transformer, therefore 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:
1, 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.
2, warning function is outstanding reliable, highly sensitive, when there being people to attempt to destroy lockhole crime, rigidly connects tactile lockhole cap, early warning type system starts immediately, because amplification effect is good, carrying load ability is strong, thereby can ensure various effect functions, use integrated circuit to make amplifier, simple in circuits is reliable, is easy to produce.
3, shooting record performance excellence.The one, before case, record is given prominence to the key points.The 2nd, there iing the owner that can automatically show announcement after record, can " not leak visit ".The 3rd, there is to do cases and can record overall process.The 4th, shooting records various ways.The 5th, in the time recording, there is time of generation.The 6th, video camera is tightly followed warning and is started, and can not damage.These 6 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, have really realized workable feature and have been.Thereby for understanding family public security present situation, there is very important positive role.
4, report to the police and start reliably, can not produce wrong report, do not affect opening the door and closing the door in normal life, there is automatic identification function, and at any time all in a kind of " highly waiting " state, protection is tight, does not affect normal habits and customs.
5, circuit is simple, and debugging is convenient, is applicable to coordinating with door, improves security personnel's performance of anti-theft safety door.
