Be the clear meaning of understanding the technical program, at first will make the following instructions:
1, before this, the inventor is studied antitheft door, and proposed 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 when normal door, send instruction by remote control to the propulsion system that are installed in the door, promote the lockset action, realize opening the door.Meanwhile, still kept the form that mechanical key opens the door, its objective is to have a kind of opening the door to remedy when automatic system goes wrong, so antitheft door can be made lockhole semiclosed processing, its meaning is, lockhole is covered during normal the use, only during out of order special circumstances, just lockhole is covered 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 the great majority crime all is by cracking of lockhole entered house.For this reason, the inventor has covered cover plate above lockhole, Men Bulu lockhole at ordinary times, on the contrary mostly be suspectable people with the people that hand is taken off lid.The record so should make a video recording, and be the important front shooting of case record.
3, based on above-mentioned situation, record three kinds of functions before the case of measure of the present invention, one of function be that shooting begins immediately as long as hand touches lockhole top cover plate, if stop to continue, automatically stop to take.Two be when automatic camera records, to have recorded simultaneously the time that occured at that time, three be occurrence record after, the Presentation Function of record before the case will be arranged, announcements in the people shooting situation once occured, to watch.
4, can preset with the rule of time period and initiatively make a video recording, namely be artificially will be set in the time on one's own initiative on a certain period, and this moment, video camera recorded ambient conditions with automatic camera, rather than will contact the lockhole cover plate.This situation mainly is for the active monitoring of the people of family to environment.It should be noted that it is whole shootings of 24 hours all day that this period comprises.
5, the shooting of the overall process after crime is produced.
6, produce the principle explanation of above function:
Produce the principle of contact lockhole cap automatic camera record: cover sheet when the hand contact is locked into lockhole, after being hole top cover plate (among Fig. 1 101), then the touch signal that has taken out human body enters the polystage amplifier amplification that not gate forms (among Fig. 1 105, to 108 etc.) by emitter follower (among Fig. 1 102) input, enter at last or door (among Fig. 1 111) input, enter at last electronic switch (among Fig. 1 112), open at last video camera work (among Fig. 1 113).If stop to continue, no touch signal then, so electronic switch is not open-minded, the camera system non-transformer is not worked.
Producing the principle of period shooting record: 116 among Fig. 1 is a kind of have time control and instruments (abbreviation time-controlling apparatus) that show, as long as preseted the time, it will output signal, through or door (among Fig. 1 111) after, open electronic switch (among Fig. 1 112), then allow video camera work.
Produce the principle of shooting record overall process: although hand has left lockhole top cover plate after forcing open the door, but above the lockhole and the alarm switch contact that is pressed under the cover plate is not oppressed by cover plate, variation has occured, and switch 119 is closed among this Fig. 1, so opened the video camera job record.
Behind the front shooting record of generation case displaying principle is arranged: 118 is a kind of rest-set flip-flops with demonstration among Fig. 1, thereby have Memorability, when each or door has output to open electronic switch 112, all can trigger the rest-set flip-flop of memory, in case so after rest-set flip-flop was triggered, additional LED can luminescence display.
The principle of shooting record writing time before the generation case: when each or door has output to open electronic switch 112, have signal to trigger the time controller, so can automatically record the moment of generation.
7, produce the warning function principle: when loosening or open the cover plate of lockhole top fully after, the alarm switch button of being satisfied with cover plate below, lockhole top does not suffer oppression and the contact changes, so started video camera work, has opened simultaneously warning system work.
8, the such installation benefit of warning starting switch be sensitive, reliable, can generation not make us terrified wrong report simultaneously.Reason one is alarm switch when event does not occur, and the 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 operation of the each starting of security system.
9, the power supply among the present invention is key component, so its circuit is made the following instructions:
(1), circuit totally consists of and principal feature: adopted traditional three end integrated circuit to make the last output of voltage stabilizing.Before the input of three end integrated circuit, increased the one-level emitter follower and made impact damper, but the design proposal one different from tradition is not contain consumable accessory zener diode, good reliability during this grade normal operation.The 2nd, thunderbolt (overvoltage) there are three grades of strick precautions, overvoltage is taken precautions against effective.The 3rd, adopted 3 measures to make adjustable, the easy accent of three end integrated circuit voltage stabilizing values.
(2), the explanation of three-level protective principle has been carried out in lightning protection.One of be between rectification and three end integrated circuit, to have increased emitter follower newly, high back-pressure high power valve is adopted in this pipe design, its back-pressure can reach hundreds of volts, almost is about 10 times of circuit of three-terminal voltage-stabilizing integrated input voltage of 78 series, is equivalent to ability to bear and has improved 10 times.Two be to have increased anti-thunder tube to make second class protection, the limiting voltage in the time of can be with thunderbolt is in the scope of tens of volts of voltage breakdown.Three be to have increased " lightning protection overvoltage backup " circuit in the base stage that output voltage is adjusted pipe, (stabilivolt 27 branch roads among Fig. 3), the duty of this pipe is, be at ordinary times the no current conducting state, its reason is that selected stabilivolt voltage stabilizing value has surpassed the over the ground pressure drop of two resistance series arms (28 and 29 series arm) of emitter follower base stage in the circuit, so by clamper.Formed like this benefit of two aspects, the one, no current during because of usual work does not produce electrical wear, so can not damage, has guaranteed reliable when using.The 2nd, when input end has high pressure; such as thunderbolt; or the civil power accident is when having high pressure; among Fig. 3 28 and 29 series arm pressure drops raise; at this moment " lightning protection overvoltage backup " branch road, (stabilivolt 27 branch roads among Fig. 3), automatically immediately conducting; newly-increased emitter follower base stage is produced pressure-limiting function immediately, implement protection.Owing to having formed the three-level protective to thunderbolt, so when bad weather, needn't be to the disconnected power down source of the present invention, and can work.
(3), can not damage the circuit explanation in civil power higher place and period.Its reason such as back and forward, thunderbolt are a kind of reasons of overvoltage.The lightning protection circuit effect is adapted to civil power unexpected the time too.
(4), can be in the explanation of the lower place of civil power and period work.Newly-increased emitter follower is high inverse-voltage tube, so the secondary low-voltage output end voltage of transformer can design higherly, when civil power is low, rectification output is had compensation like this.Therefore expanded the civil power lower range.
(5), can expand the explanation of civil power variation range.Its reason is that civil power does not damage circuit when high, and when low compensation is arranged, so expanded the operation interval that civil power changes.
(6), take three-terminal voltage-stabilizing value Several Measures adjustable and that easily transfer.One of, be designed with three ends adjustment voltage stabilizing and be worth adjustable peripheral circuit, formed by 33,34,35 3 elements in this circuit.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve easily batch production and the contradiction of adjusting flexibly voltage.Because three end integrated circuit models and individual difference, the electric current that earth terminal flows out is variant, if only is connected with resistance between its earth terminal and the ground connection, then the resistance of similar resistance is not easy to produce the consistance of pressure drop, the difficult batch production in batches.Then can address this problem with diode, only the electric current of pipe inflow diode has the difference of size, and its pressure drop is 0.7 volt, so batch production need not be adjusted.If but this branch road is only used diode, but can not adjust flexibly required voltage stabilizing fractional value, so the present invention has adopted the adjustment branch road of both series connection, in this branch road, diode is coarse adjustment, because being the major part of pressure drop; And the pressure drop of institute's resistance in series is minute portions, is accurate adjustment.Three, in adjustable peripheral element, increase by one road branch road (33 Fig. 3) from the output of three ends, to strengthen easy batch production.Because the electric current of this branch road occupies larger specific gravity in diode and resistance series arm, beneficial to overcoming three end integrated circuit models and individual difference, be conducive to batch production.The rule of adjusting the three-terminal voltage-stabilizing value is, resistance 34 among Fig. 3, and resistance is higher, and output voltage is higher, otherwise lower.
(7), improve the Several Measures of reliability: one of, in lightning protection circuit, formed three-level protective, (seeing second).Two, the impact damper base presses Circuit tuning to be comprised of resistance series arm (28 and 29 series arms among Fig. 3); do not contain easy failed part voltage stabilizing diode, not fragile, three; in the protection of the lightning protection third level, design " special substitutes " protected mode branch road, further improved reliability.
After the invention process, the anti-theft security goalkeeper presents a kind of brand-new looks, and following outstanding advantage is arranged:
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 have the function that the 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, the shooting record performance is excellent.The one, record is given prominence to the key points before the case.The 2nd, after being arranged, record can automatically show the owner of announcement, can " not leak visit ".The 3rd, cases has occured to do can record overall process.The 4th, shooting records various ways.The 5th, in when record time of generation is arranged.These 5 meanings have return visit and save time, economize energy, save device resource etc. serial advantage, have realized that really workable characteristics are.(in the situation of work strain, family can not carry out " return visit " to shooting by impunity, more impossible in return visit, watch a lot of useless general impunities records).Thereby for understanding the family public security present situation, very important positive role is arranged.
3, warning function is reliable and sensitive, does not importantly produce wrong report.
4, reliable, easy to use.Reason one be video camera recorder and warning system at ordinary times most cases be in the no power state, do not produce electrical wear, all be at any time a kind of " highly waiting " state, the 2nd, closing the door when opening without any need for other additional move user between the whole operating period, do not affect normal habits and customs, can not produce malfunctioning situation.
5, the amplifying circuit of shooting record automatic control unit is outstanding before the case, has guaranteed the reliable and sensitive of core circuit.Reason one is that emitter follower can realize that the coupling between lockhole cover plate and the amplifier takes out signal reliably after as impact damper well.The 2nd, the sensitivity at different levels of amplifier is adjustable flexibly, and very high amplification coefficient is arranged.The 3rd, functional level has good shaping operation, realized the Digital output conversion of (0) with (1) of standard, thereby resolving power is very strong; Export simultaneously energy large, there is very strong triggering ability in subordinate.
6, produce easily, the one, the simple and reliable debugging of circuit is easy, and the 2nd, do not need the instrument and meter of price top grade.
The power source performance of 7, joining is good: (1), performance are good, embody in the following areas: the one, and anti-thunder is effective, has the lightning protection three-level protective, and not fragile at thunderstorm season, supporting electrical equipment needn't quit work at thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage supply wider adaptive faculty is arranged, namely be to make the protector of joining work and can damaging when the high place of voltage and period or accidental cause, and also can work in voltage lower place and period.The 3rd,, can be used for exporting the voltage stabilizing value that there is decimal in generation.And the existing achievement of inventor is security personnel's classes, need to be to the floating charge circuit of accumulator, and this circuit can not be round values.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.
(2), reliable.Reason one is that in electronic circuit, voltage stabilizing diode also is one of easy failed part, and in the present invention, stabilivolt has been done special processing, so reliability is higher than traditional co-design.Reason two is, newly-increased emitter follower Guan Weigao back-pressure high power valve among the present invention, and reliability generally all is much higher than common triode.
(3), debug conveniently easily batch production.
