Description
Technical field
It the utility model is related to smart home field, and in particular to a kind of intelligent detection device for antitheft door.
Background technology
Common safe-guard door lock is all to be exposed at outdoors, and the reinforcing of in general theftproof performance is all the internal junction from safe-guard door lock
Structure is started with, and with the improvement of lockset, unlocking tool also gradually increases, and simple lifting lockset internal structure can not meet existing
In the safety requirements of people.It is that unlocking tool is inserted into lockhole mostly when being opened the door using unlocking tool, carries out anti-
Multiple amendment so that unlocking tool progressively pushes up out the thimble in lock core, so as to realize unlocking.
Existing antitheft door uses mechanical anti-theft lock mostly（Use mechanical key）, do not possess and detected whether unlocking tool
The function of unlocking.With attention of the people to safety, there is antitheft door and detected whether that unlocking tool enabling is that have huge city
Field potentiality.
Therefore, be badly in need of now it is a kind of enable to antitheft door have detect whether unlocking tool open the door detection means.
Utility model content
The technical problem of solution of the present utility model is to provide a kind of so that antitheft door, which has, has detected whether unlocking work
Has the intelligent detection device for antitheft door to open the door.
Base case provided by the utility model is：For the intelligent detection device of antitheft door, including：
Sleeve pipe, sleeve pipe is interior to be provided with magnet steel, induction coil is wound with outside sleeve pipe, sleeve pipe is embedded in antitheft door, magnet steel and sleeve pipe
It is slidably matched, elastic component is provided between the end of magnet steel and antitheft door, sleeve pipe includes inner spout and outer spout, and inner spout is positioned at anti-
Steal in door, outer spout flushes with antitheft door；
Contact reed, contact reed include movable contact spring and determine reed, determine reed and be fixed on the doorframe of antitheft door, move
Reed is fixed on the side of antitheft door, movable contact spring and determines reed and is brought into close contact when antitheft door is closed, movable contact spring and induction coil
Between be provided with wire；
Voltage detector, voltage detector and determines to be provided with wire between reed；
Controller, controller electrically connect with voltage detector, and controller is electrically connected with timer and buzzer, and controller connects
After the signal for receiving voltage detector feedback, controller sends enabling signal to timer, and timer starts timing, and controller stops
After the signal for receiving voltage detector feedback, controller sends stop signal, timer timing parameter zero to timer；Meter
When device timing exceed threshold value after, timer feeds back abnormal signal to controller, and controller receives the abnormal letter of timer feedback
Enabling signal is sent to buzzer after number, buzzer sends sound after receiving enabling signal.
Operation principle and advantage of the present utility model are：When antitheft door is closed, if someone unlocks
Instrument is unlocked, during correcting repeatedly, it will so that antitheft door produces vibration.If it happens antitheft door vibrates, that
Magnet steel in sleeve pipe also can be relative to set tube vibration, and magnet steel can move, the line of induction in vibration processes relative to induction coil
Induced electromotive force will be produced in turn coil, induced electricity dynamic formula is delivered to voltage detector by conductive contact formula reed and is detected
Out.
Testing result is fed back to controller by voltage detector, and controller sends enabling signal to timer, and timer is opened
Beginning timing, controller stop after receiving the signal that voltage detector feeds back, and controller sends stop signal, timing to timer
Device timing parameter is zeroed；After exceeding threshold value during timer（I.e. vibration is more than after certain time）, timer is anti-to controller
Abnormal signal is presented, controller receives after receiving the abnormal signal of timer feedback to buzzer transmission enabling signal, buzzer
Sound is sent after to enabling signal.If only needing the 5-10 seconds if the just normally opened door of owner, if unlocking tool is opened
If door, according to the standard of present B levels lock, anti-technology is opened（Prevent unlocking tool from opening）Time requirement at 5 minutes
More than.Therefore add timer and threshold value can effectively distinguish the just normally opened door of owner or abnormal unlocking tool opens the door.
Contact reed, contact reed include movable contact spring and determine reed, determine reed and be fixed on the doorframe of antitheft door, move
Reed is fixed on the side of antitheft door, movable contact spring and determines reed and is brought into close contact when antitheft door is closed.So design be in order to
Stop the detection to vibration after opening door, avoid reporting by mistake.Only under shutdown state, there are abnormal vibrations in antitheft door, during vibration
Between exceed threshold value after, buzzer can just alarm, and reduce the possibility of wrong report.
If owner needs carry out technology unlatching, or because enabling posture is not right, delays many times, now also have
It is likely to occur the situation of wrong report.But because the outer spout of sleeve pipe flushes with antitheft door, owner is only needed magnetic with a push rod
Steel heads into sleeve pipe depths, and magnet steel would not vibrate, and further reduce the possibility of wrong report.
The utility model is used for the intelligent detection device of antitheft door, passes through the phase interworking of magnet steel, sleeve pipe and induction coil
Close, be able to detect that the vibration of antitheft door, by the design of contact reed, allow this vibration detection to be only capable of in shutdown state
Avoid the possibility of wrong report.By timer, tell owner and opening door or other people use unlocking tool
Opening door.So that antitheft door is provided with the function that detection room-mate has unlocking tool to open the door.
Further, camouflage baffle plate is provided with outer spout, camouflage baffle plate is connected with casing threads, pretended between baffle plate and magnet steel
Provided with spring.Such design one is to avoid other people from finding magnet steel so as to withstand magnet steel, does not allow magnet steel to vibrate；Second, pass through bullet
Spring coordinates sensitivity of the increase magnet steel to vibration with elastic component
Further, analog-to-digital conversion device is provided between controller and voltage detector.Such design is to control for convenience
Device identifies the signal of voltage detector feedback.
Further, the both ends of magnet steel are provided with the rhotanium collar, and elastic component and spring are connected with the rhotanium collar respectively.
The rhotanium collar more grinds more light, can reduce the friction between magnet steel and sleeve pipe, ensures sensitivity of the magnet steel to vibration detection.
Further, induction coil includes first coil and the second coil, and gap is left between first coil and the second coil,
First coil and the second coil are wrapped in outside of sleeve, are connected between first coil and the second coil and allow both induction electrics
The wire that gesture is added.The sensitivity that the vibration of magnet steel is converted into voltage by induction coil can so be improved.
Further, it is impregnated with one layer of inorganic insulation layer on first coil and the second coil.Such design is to protect
First coil and the second coil are protected, improves service life.
