Description
One, technical field
The utility model relates to a kind of security door product, specifically is a kind ofly can carry out analysis and judgement to a plurality of sensor input signals, and can takes the intelligent anti-theft door of anti-theft measure automatically.
Two, background technology
Along with the development of electronic technology and modern manufacturing industry, a kind of security product that is called as intelligent anti-theft door quietly comes out.Intelligent anti-theft door is generally made a general reference the logical process chip is installed on the basis of common security door, has situation more than at least 2 kinds (input signal) is carried out analysis and judgement and taked the class product of anti-theft measure (output) automatically.The appearance of these products has greatly improved the technological prevention ability of security door, and cracking a crib to the robber has increased technical difficulty.In the past, the steadiness that increase security door generally all adopts the intensity that increases door or improve lockset, methods such as structure realize.Along with development of electronic technology, the intelligent level of security door is more and more higher.The anti-theft measure major part that these products are taked is automatic alarm type, and its type of alarm has on-the-spot sound and light alarm and the remote alarms by communication tool.Also have plenty of the mode of employing image scene (video), sound (audio frequency) record, give a clue to ex-post analysis.It perhaps is exactly the various combination of above-mentioned several precautionary measures.But no matter above-mentioned what precautionary measures can only be deterred robber's psychology of committing a crime, and can not stop and continue crime.For some professional robbers, when these containment facilities start, can also open door leaf in the same old way and continue crime.In case door is opened by the robber, the robber can in time close warning, destroys all deterrent measures (as cut off the electricity supply etc.), erases all and leaves over vestige (as destroying record facility etc.).Make all precautionary measures perform practically no function.These measures all can not really be played the effect that prevents stolen property from the strict sense, onsite alarming, and on-the-spot record all is an anti-theft measure passive behind the something.Door is opened after all, and property loss is unavoidable.Though, also have can be when finding the robber technology of automatic stuck lock core, reach the purpose that the robber can't continue to unblank.But the robber often destroys this weakest link of lock core and the crime of entering the room, and continues crime so also can't stop the robber to open door leaf.Really, a kind of security and guard technology that is called the robber-captured type anti-theft measure is arranged also, when finding the robber, with automatic handcuffss or refer to handcuff the robber and limit its freedom of person, as if can stop the robber to continue to commit a crime.But, this method human body is constituted the risk of injury and to owner's potential threat much larger than stolen risk, also have a suitable segment distance from practicality.The product close with the present invention seen patent documentation ZL01107211.3, the patent of invention of " intelligent anti-theft door " by name.A kind of intelligent anti-theft gate technique is disclosed.But because this invention self-locking device adopts motor-driven, shortcoming is that slow movement, response time are long, and when robber's violence was opened the door, self-locking device did not also have the reaction door to be opened, has lost the meaning of self-locking.Moreover, in case self-locking device works, must input password by motor counter-rotating ability " release " by keyboard.This has just brought two problems: if a robber cuts off the electricity supply in advance, just might make self-locking device malfunctioning, perhaps can not lock, and perhaps can not release.Two, the pilferage accident taking place is a small probability event, a people also seldom runs into once a lifetime, allow a people go all one's life to remember or preserve one group of unlocking pin, allowing a tripper that overlaps the complexity of being made up of code keypad, motor etc. guarantee its result of use under rare expendable situation, almost is impossible.In addition, also owing to the circuit complexity, link is many, reliability is lower etc., and reason also can hinder its application.Therefore, it is simple, reliable, easy to use how to utilize high-tech means and modern manufacturing industry level to produce, really can stop the robber enter the room the crime intelligent anti-theft door be the product that this industry is being seek assiduously always.
Three, summary of the invention
The purpose of this utility model is the above-mentioned defective at present like product, designs a kind of simple in structure, reliable in action, convenient and practical; A unification of structure, the security door intelligent platform that can constantly upgrade; Can not only in time report to the police when discovery has the robber, write down (on-the-spot audiovisual/visual information) automatically, and can rapidly door leaf be pinned automatically; Can only door leaf is further locked when the robber continues to destroy, what increase the difficulty of forcing open the door can really resist the multifunctional intellectual security door that the robber enters the room and commits a crime.
The technical scheme in the invention for solving the technical problem is:
One cover intelligent inductor is housed, a cover central processing unit and a cover self-locking alarm device and the supply unit that energy is provided for whole system in the door leaf of common security door.Described intelligent inductor include, but is not limited to can sensed activity image, take in the intelligent electron eye of environment sound equipment, the human body sensor that constitutes by ultrasonic wave, microwave, principle such as infrared, can respond to the door condition sensor of door leaf position, the lock core sensor on the door lock, prevent classical signal devices such as the heat sensor of flame cutting, the modern sensor part such as vibrating sensor that prevents machine cut (comprise hit door, force open the door) and button, switch.Described central processing unit include, but is not limited to carry out little process chip of logical operation and for its supporting I/O, clock, the big capacity non-volatile solid state memory that peripheral chip such as latchs, provide operand store, the program storage that operational order is provided and the store data of the temporary usefulness of microprocessor operational data to use.Described self-locking alarm device includes, but is not limited to the output device of a series of anti-theft measures such as automatically controlled automatic locking, audible-visual annunciator, long-distance alarm apparatus, on-the-spot digitizing video automatically.Described supply unit is the double power-supply system of the complementary power supply of a cover alternating current-direct current.
Described intelligent inductor connects with described central processing unit by input circuit, and described central processing unit connects with described self-locking alarm device by output circuit.Described input circuit, output circuit and central processing unit have constituted the intelligent platform of described intelligent self-locking security door, can extend application and the function that makes new advances by increase or combinatorial input, output condition.For example, increase a button, can increase the doorbell function at input circuit; Increase a display screen again at output circuit, can increase the video doorbell function again.。。。。Or the like.
Described door condition sensor is a switching mode sensor, is installed on the door leaf from door-hinge place farthest.Such installation is to consider to improve transducer sensitivity to greatest extent.State of (state of closing the door) sensor output when door leaf is close to doorframe, (door opening state) sensor is exported another state when door leaf leaves doorframe.The conversion of two states (distance of reaction that claims sensor), design is left about 5 mm distance at door leaf and doorframe from being close to the position.Distance of reaction is decided on the machining accuracy of door.Principle is: door all can not make the state sensor action in any case shake door under lock-out state.Be sure of that door has left latched position, state sensor must move immediately.
Described lock core sensor is one group of switching mode sensor that is installed on the door lock.Whether the output state of sensor should be able to reflect has key to insert lock core, and whether lock core rotates, and whether door lock is opened by Internal handle, and whether stop button is in safety position.
Described central processing unit adopts the array scanning technology, constantly each intelligent inductor is passed the signal of telecommunication of coming and carries out analysis and judgement.In case find to have illegal invasion, start the self-locking alarm device by output circuit immediately and automatically lock, and start automatic sound-light alarm and the on-the-spot audiovisual/visual information of automatic record.A kind of typical illegal invasion approach is: the robber unblanks with so-called master key.At this moment, the lock core sensor provides a signal that key unlocking is arranged, and central processing unit picks up counting.(lock core rotation sensor and door condition sensor send signal in succession) just started at gate time end back door in regulation, and promptly decidable is non-method invasion.Because, there are data to show open the door also slow tens times of speed of the fastest master key than the slowest normal door speed, central processing unit just is being based on that this time difference judges.Another kind of typical illegal invasion approach is: the robber walks around lock core and unblanks by the other technologies means.At this moment, the lock core sensor has not provided key unlocking and lock core turn signal, or has only one of them signal, and door is started (door condition sensor sends signal) and can think illegal invasion in this case.Other several typical illegal invasion approach ratios are easier to judge, for example, flame cutting, machine cut (comprise pound the door, force open the door etc.), chemical explosion etc. all have the supply of commodity sensor on the market, do not repeat them here.Along with the development of technology, reply lawless person's intellectuality trend, new senser element also can continue to bring out.These all may become the initial conditions of described central processing unit, increase the arbitration functions of central processing unit.
Described lock core sensor and door condition sensor are judged the illegal invasion condition except central processing unit is provided, can also provide central processing unit to judge that whether owner forgets key on lock core, whether door closure has been locked etc. that some are slipped up once in a while, prevents the accidental loss that people cause because of accidental error in modes such as warning, self-lockings.
Described automatically controlled automatic locking is locked by electric pulse control, and pure machine driving resets (release), is made up of locking bolt, energy storage device, linkage, electromagnet and resetting-mechanism, is installed on the position of door-hinge about 2/3.Described locking bolt is connected with described linkage respectively put up and down one (be commonly called as world lock, also can increase severally at side again, principle is identical) of door leaf, makes two locking bolts to stretch simultaneously.Described energy storage device is installed between locking bolt and the linkage.Linkage is blocked by electromagnet armature on the position of corresponding locking bolt indentation, and at this moment, described energy storage device is in the energy storage position.Described resetting-mechanism is made up of the coupling mechanism of lock core, the big speed ratio transmission mechanism (for example ratchet, screw rod, worm gear etc.) with self-locking property and energy drivening rod mechanism action.This coupling mechanism has self-destroying function, when any one is destroyed when lock core, transmission mechanism or linkage, can break away from connection automatically, and automatically controlled automatic locking can not be resetted.When central processing unit provided lock signal, electromagnet obtained a pulse voltage adhesive armature.Locking bolt is under the acting in conjunction of linkage and energy storage device, and moment ejects door leaf and blocks doorframe, finishes the action of once locking.In case lock, can only slowly locking bolt be resetted by resetting means with owner's key.If also entertaining a gleam of hope attempt, robber's this moment unties automatic locking, two selections nothing but, continue to use master key: because the design that resets of automatically controlled automatic locking is based on interim application, adopt the big speed ratio transmission mechanism consciously reseting procedure to be prolonged (also helping the energy storage in the reseting procedure) so that use when locking once more.For example, have a design to adopt worm gear to make transmission mechanism, lock core drives worm screw and resets by the worm gear drives locking bolt.This design is lock core will be rotated tens to change even commentaries on classics up to a hundred could reset locking bolt, and master key can only tackle the sort of lock core as long as change the lock that can open once, two circles.Therefore for this design, master key is helpless.Even the robber has improved master key, owing to this moment alarm bell your writing, the patient continuation crime of the exhausted at this moment nothing of robber.Perhaps destroying lock core attempt stirs linkage and unblank: for example punch lock core with electric drill in previous example, cut off the connection of resetting-mechanism and linkage this moment in fact, and automatically controlled automatic locking can't reset again, and door leaf will can't be opened forever.Do not say the robber, even owner goes home also must remove whole door and doorframe just can be entered the room.This moment, the robber lost original intention and the meaning destroyed.Naturally beat a retreat in the face of difficulties.
Described audible-visual annunciator is formed (also can add warning lamp in case of necessity) by speech chip and high-decibel loudspeaker, and controlling it by central processing unit, to send chimes of doom still be doorbell sound.Report to the police in case start, as long as find that it is continuous alarm at the scene that the people is arranged, deterring criminal hastens to leave the scene on the one hand, reminds other people's vigilance on the other hand.Very important person one leaves the scene, when for example leaving 0.5 meter of door leaf, promptly stops to report to the police.Demonstrate fully the level of intelligence of central processing unit, avoided meaningless electrical source consumption again.
Described long-distance alarm apparatus is according to the suitable communication exchange device of communication terminal equipment configuration, for example beeper, mobile phone, multimedia message, note, broadband, phone etc.Can finish the real time remote transmission of voice, literal, image scene even live video.For in time handling alert event, the victim provides on-the-spot first-hand data.
The automatic digitizing video in described scene is made up of camera, microtelephone, high speed A device, digital video-audio compression process chip, non-volatile solid-state memory etc.Under the control of central processing unit, promptly begin video recording as the people near door (for example 0.5 meter in), the people leaves and promptly stops video recording.If there is not alert event to take place, next video recording will cover the video recording (if video recording mode that memory span enough also can adopt repeatedly record circulation to cover greatly) of last time.If there is alert event to take place, promptly stay all Video Documents that this has comprised alert event several periods of front and back for the last time, no longer cover.For the ex-post analysis merit is given a clue.Described non-volatile solid-state memory volume is very little, can be installed in the insulated steel seal box, and the test of adverse circumstances such as ability fire, big flood, earthquake, artificial destruction for studying the natural and man-made calamities of these bursts, keeps valuable data.
Described power-supply system is made up of AC/DC convertor, dc-battery group and power management module.When powering with the mains ac power supply, alternating current becomes direct current by AC/DC convertor powers to system, and gives batteries charging by power management module, and system's electricity consumption is required during in order to the alternating current outage.Because system has adopted the power saving design, so also can adopt the power supply of dc-battery group separately.At this moment, power management module can detect battery electric quantity automatically.When electric weight is not enough, can report to the police automatically, remind the user to change battery or charging in time.
Above-mentionedly being the input system of feature, arithmetic system that central processing unit is the center and being the intelligent platform of the intelligent anti-theft door formed of the output system of representative by the self-locking alarm device by intelligence sensor, is a kind of modularization, building block system mentality of designing.On this platform, above-mentioned each functional module is the function that makes new advances of independent assortment as required; Or the increase module increases the new function of security door.For example, increasing a camera behind the door, just the monitoring of outdoors single face can expanded to outdoors, indoor bidirectional monitoring.Or the deletion certain module, reduce cost, adapt to the more consumer group.For example, the minimum system that door condition sensor, lock core sensor and automatically controlled automatic locking just can be formed an intelligent self-locking security door only is installed.With the basic model of this minimum system as product.Other add module as extended pattern according to user's needs, can form the series of products of intelligent self-locking security door thus.
The beneficial effects of the utility model are: one, introduced central processing unit for the intelligent anti-theft door product, made up intelligent platform, for industrialization, the producing in serial form of intelligent anti-theft door product lays the foundation.Two, invented automatically controlled automatic locking.Its, auto-lock function guaranteed that door is not illegally opened moment, really made security door become robber's unbreakable barrier together.Its pure mechanical slow-action resetting means has guaranteed that legal people does not untie self-locking with not taking thinking at any time, and allows the robber hope lock heave a sigh.Three, owing to made up intelligent platform, introduce central processing unit, simplified input circuit (sensor) greatly, strengthened output function (anti-theft measure).

Fig. 9 is the A-C sectional drawing of Fig. 2, expression be the schematic diagram of door condition sensor (6) at operating position.Door condition sensor (6) is served as by travel switch, and its stroke distances is adjusted into 5mm.
Below in conjunction with the various situations that door is unlocked, the operating principle of present embodiment is described:
When 1, normally turning the key in the lock, key insertion lock core (52) promotion fan shape baffle A (55) slides vertically and at first blocks photoelectric tube (57) as shown in Figure 5, G1 provides a key and inserts signal, and then rotational lock core (52) is pushed dead bolt (51) open and is unblanked, drive fan shape baffle A (55) rotation simultaneously, block photoelectric tube (58) G2 then and provide unlocking signal.Central processing unit (3) promptly picks up counting after receiving the G1 signal, receives the unlocking signal of G2 in predetermined delay time, promptly thinks normally to unblank, and door is normally opened.
When 2, owner is from the door inward, moving Internal handle unblanks, this moment, Internal handle (53) promoted fan shape baffle B (56) rotation when pushing dead bolt (51) open as shown in Figure 5, block photoelectric tube (57) and (58) in succession, situation is identical when opening the door with normal key, G1, G2 provide signal in succession, and central processing unit (3) is thought normally to unblank, and door is allowed to open.
3, after door was normally opened at every turn, central processing unit (3) a period of time of all will delaying time shielded the signal of vibrating sensor (9), is judged by accident disconnected to avoid normal vibration at closing time.
4, when the guest rings a doorbell button (10), central processing unit (3) output doorbell signal, the prompting owner opens the door.
If after 5 owners open the door key is forgotten to pull up at Men Shangwei, photoelectric tube this moment (57) continues to be blocked, and central processing unit (3) will be exported prompting and pipe, and reminds owner to pull up key.
If 6 central processing units (3) detect door condition sensor (6) show gate for a long time in opening, i.e. output prompting pipes, and reminds owner to close the door.If consciously door is in opening, Internal handle (53) can be fastened with stop button (54), central processing unit (3) can decision gate be normal opening, cancellation prompting automatically.If forget, door closure should be prevented that accidental error from causing robbery accident with door closure.Also might owner go out no one's processing prompt message.Central processing unit (3) will be opened automatically controlled automatic locking (4) door will be pinned and the startup automatic sound-light alarm automatically after output prompting a period of time.To avoid accident further to enlarge.
7, when the robber unblanks with master key, three kinds of situations will take place: a kind of situation is fan shape baffle A (55) not to be promoted, central processing unit (3) is at the signal that can not get G1, G2, just detect door that door condition sensor (6) the provides signal that is opened, can export self-locking this moment immediately and report to the police automatically.Second kind of situation is that fan shape baffle A (55) is pushed, but because the time that master key is unblanked is much larger than the uncaging time of normal key, the sigtnal interval that is G1 and G2 has surpassed predetermined delay time, central processing unit (3) still can be given the signal moment of going out and being opened at door condition sensor, opens automatically controlled automatic locking automatically and starts automatic sound-light alarm.The third situation is fan shape baffle A (55) not to be promoted, but fan shape baffle A (55) also can rotate under the drive of lock core or other external force, do not endwisely slip owing to fan shape baffle A (55) this moment, can not block photoelectric tube (57) (58) even rotate yet, its situation is the same with first kind of situation, also can suffer the self-locking of central processing unit (3) and warning automatically.
8, when the robber unblanks with additive method, for example unblank with inserted sheet picking lock tongue, this moment, fan-shaped catch A and B all can not move as seen from Figure 5, photoelectric tube (57), (58) do not have any output, and first and third situation same central processor (3) can be exported self-locking and warning automatically immediately in the situation and above-mentioned 7.
9, when the robber destroys door leaf (1) with the mode of flame cutting, be distributed in door leaf heat sensor (8) everywhere meeting output signal at once, as long as there is a heat sensor to send the thermoinduction signal, central processing unit (3) will store signal, in the regular hour, as long as Men Yidong (door condition sensor signal) will export self-locking immediately and report to the police automatically.
10, when the robber destroyed door leaf (1) or doorframe (2) with door or the crowbar mode such as force open the door of hitting, huge bump vibration can make vibrating sensor (9) output signal immediately.With above-mentioned 9 in like manner, central processing unit (3) can be taked anti-theft measure by same handling procedure.Though, normally also can produce the bump vibration sometimes at closing time, central processing unit this moment (3) has a refractory period (seeing above-mentioned 3) so can not occur judging by accident disconnected.
Vibrating sensor (9) is a kind of like this sensing device: export a signal of telecommunication when the vibration amplitude of impression or vibration frequency surpass certain threshold value.
11, when the robber with other machine cuts devices, when for example destroying door leaf (1) or doorframe (2) with apparatuses such as Abrasive cutting off machine, pistol electric drills, the high-frequency vibration of machine cuts can make vibrating sensor (9) output signal immediately, and central processing unit (3) starts self-locking at once and reports to the police automatically.
12, as people's mischief or child are unconscious when hitting, though vibrating sensor might output signal, this moment, door can not be opened, and central processing unit (3) can not exported any action.Prevented this have a mind to or the situation of being not intended under erroneous judgement disconnected, improved the operation precision and the degree of reliability of intelligent anti-theft door.
13, Figure 10 is the contour structures schematic diagram of intelligent electron eye (7), and wide-angle imaging head (71), high-sensitivity miniature microphone (72) and Infrared Detectors (73) are housed above.The detection range of Infrared Detectors (73) is adjusted into 0.5 meter.When having the people to enter detection range near door leaf, Infrared Detectors (73) output induced signal, central processing unit (3) starts digitizing video device (13) and begins video recording, the looking of camera (71) and microtelephone (72) picked-up, audio signal are recorded in the solid-state memory (32) after the overcompression process chip is handled, leave the infrared acquisition scope until the people.Selected solid-state memory (32) is a non-volatile solid state memory, and memory capacity is 2Gbits.Can store about 40 minutes video recording data.For conserve storage, filter invalid information, Useful Information can be remained again simultaneously, central processing unit (3) has been taked following video recording strategy: record a video when only having the people movable in detection range, each video recording produces a file, each document order storage is covered with whole memory until N file.(N+1) individual file covers the memory location of first file, so repeatedly circulation.In case alert event has for example taken place in the generation alert event when K file, then cover to (K-J) individual file stop to cover (N 〉=K〉0, N J 0).Solid-state memory this moment (32) has just kept incident front and back Video Document has for several times taken place.For review the cause of accident and the police solve a case the sound of the most directly perceived, best opportunity is provided, as data.
14, when producing the self-locking alarm incident, central processing unit (3) can be according to the signal output situation of Infrared Detectors (73), the course of action of guide sound light crossing-signal (11).Have only when the people is close just to allow audible-visual annunciator send the sound, the people leaves promptly and stops.The deterrence robber dare not continue crime, reminds other people that there is something special herein, avoids consuming meaningless electric energy.
15, when producing the self-locking alarm incident, central processing unit (3) can also start long-distance alarm apparatus (12), the communicating terminal (for example telephone) that is preset in the long-distance alarm apparatus is connected, sent to communicating terminal according in advance setting or with alarm voice or with photo site or with live video.So that in time handle alert event.
