2, lockhole switch be one without self-locking type pushbutton switch, within being contained in ring flange, expose button.

For having a clear understanding of the meaning of the technical program, first will make the following instructions:

1, before this, inventor is studied antitheft door, and propose normal door and opened the door without mechanical key, but the measure of the mode of opening the door with electronics telecontrol engineering or phone.Be in the time of normal door, send instruction by remote control to the propulsion system that are installed in door, promote lockset action, realization is opened the door.Meanwhile, still retain the form that mechanical key opens the door, its objective is that in the time that automatic system goes wrong, can have one to open the door makes up, so antitheft door can be made lockhole semiclosed processing, its meaning is, when normal use, lockhole is covered, and only when out of order special circumstances, just lockhole is covered to sheet and is opened.

2, it is reported, to the security personnel of family, the most important thing is the security personnel of opposite house, and the security personnel of opposite house, emphasis is again the security personnel to lockhole, because great majority crime is all by cracking of lockhole entered house.For this reason, inventor has covered cover plate above lockhole, Men Bulu lockhole at ordinary times, otherwise with the people that hand is taken off lid be mostly suspectable people.The record so should make a video recording, and be the important front shooting of case record.

3, based on above-mentioned situation, before the case of measure of the present invention, record three kinds of functions, one of function be that shooting starts immediately as long as hand touches lockhole top cover plate, if stop continuing, automatically stop shooting.Two be in the time that automatic camera records, to have recorded the time occurring at that time simultaneously, three be occurrence record after, will have the Presentation Function recording before case, announcements in people once there is overwriting situation, to watch.

4, can preset the initiatively shooting of rule with the time period, be artificially will be set on one's own initiative a certain period time above, and now automatic camera is recorded ambient conditions by video camera, instead of will contact lockhole cover plate.This situation is mainly used for the active monitoring of people to environment in family.It should be noted that it is whole shootings of 24 hours all day that this period comprises.

5, the shooting to the overall process after crime generation.

6, produce the principle explanation of above function: (explain with Fig. 1.）

Produce the principle of contact lockhole cap automatic camera record: when criminal's hand touches after the signal leading sheet of lockhole top, just be imported in the in-phase end of operational amplifier of the first order and amplify, being input to again afterwards comparison amplifier further amplifies, this have a very large gain, can fully ensure sensitivity and the reliability of pre-alarm signal.Its reason is in this circuit, the resistance of first order operation amplifier level (in Fig. 1 103) can be adjusted the gain of this grade flexibly, and the divider resistance ratio (109 in accompanying drawing 1) of adjusting the comparison amplifier end of oppisite phase of second level operation amplifier level composition can be adjusted again the gain of this grade flexibly.

Produce the principle of period shooting record: 116 in Fig. 1 is a kind of instruments (abbreviation time-controlling apparatus) with time controller and demonstration, as long as preset the time, it will output signal, through or door (in Fig. 1 111) after, open electronic switch (in Fig. 1 112), then allow video camera work.

The principle of shooting record writing time before generation case: when each or door has output to open electronic switch 112, have signal to trigger time controller, so can automatically record the moment of generation.

7, produce warning function principle: when door and doorframe are subjected to displacement, the travel switch contact of pacifying every and doorframe junction changes, and has produced warning enabling signal; When becoming flexible or opening completely after the cover plate of lockhole top, the lockhole shift knob of being satisfied with cover plate below, lockhole top does not suffer oppression and contact changes, also produce warning enabling signal, the contact of biswitch starts video camera work, has opened warning system work simultaneously.

8, the such installation benefit of warning starting switch be sensitive, reliable, simultaneously can generation not make us terrified wrong report.Reason one is alarm switch while there is not event, and contact can not be subjected to displacement.The 2nd, do not affect the normal habits and customs of people, thereby do not affect the normal work of the each starting of security system.

9, the principle of sound system is: formed by a triode prestage that sound equipment amplifies, form complementary circuit by a power amplifier PNP pipe with power amplifier NPN pipe audio frequency has been carried out to power amplifier, in the time having pre-alarm signal, the power supply of having opened this part is controlled in its output, so have voice to produce, due to this electric circuit constitute be an OTL instead of OCL circuit, so debugging is simple, and have element not perishable, and the higher advantage of efficiency.

After the invention process, anti-theft security goalkeeper presents a kind of brand-new looks, has following outstanding advantage:

1, after the invention process, anti-theft safety door and alarm have been realized the combination of science, three kinds of functions integrate, one of be to there is the function that people is kept outside the door, two are the functions with automatic camera record, three are the functions of reporting to the police, three kinds of functions are all very important, promote all sidedly security personnel's performance of anti-theft safety door, enriched the kind of antitheft door.

2, shooting with video-corder operation circuit has very high sensitivity and reliability, after debugging, is all applicable to all-environment needs, and circuit is simple, and debugging is convenient.

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.These 5 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, have really realized workable feature and have 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.

4, warning function is reliable and sensitive, does not importantly produce wrong report.

5, reliable, easy to use.Reason one be video camera recorder and warning system at ordinary times most cases in no power state, do not produce electrical wear, at any time all in a kind of " highly waiting " state, the 2nd, user between the whole operating period closing the door when opening without any need for other additional move, do not affect normal habits and customs, can not produce malfunctioning situation.

6, produce easily, do not need the instrument and meter of price top grade.
