Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model access control device.
Fig. 2 is the circuit block diagram of the utility model access control device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment: as shown in Figure 1 and Figure 2, a kind of access control device, comprises Fingerprint Identification Unit 1, supervising device 2 and locking mechanism 3.
Particularly, locking mechanism 3 comprise with lockhole with the use of locking bolt 30, lock 31, back-moving spring 32, connecting rod 33, screw rod 34 and drive unit 35.Locking bolt 30 is through the back-up block 310 with lock 31, and back-moving spring 32 one end is fixedly connected with locking bolt 30, and the back-up block 310 of the other end lock 31 of back-moving spring 32 is fixedly connected with.Outstanding formation screw sleeve 311 on lock 31, connecting rod 33 is bending, one end of connecting rod 33 and locking bolt 30 hinge-connection, the other end of connecting rod 33 is placed on screw sleeve 311, connecting rod 33 is provided with pin hole 330 in the junction with screw sleeve 311, screw rod 34 passes lock 31 and screw rod 34 is movably set with the latch 340 matched with pin hole 330, screw rod 34 is a hollow structure, one end of latch 340 is fixedly connected with screw rod 34 wall by spring, the other end of latch 340 passes the inner space of screw rod 34, screw rod 34 is provided with electromagnet 341 with the junction of spring, latch 340 is equipped with the first permanent magnet with the junction collection of spring.The gear set that drive unit 35 comprises stepper motor 350 and is connected with the rotation axis of stepper motor 350, one end of gear set and screw rod 34 is meshing.
Supervising device 2 comprises: the Hall element 21, the controller 22 be connected with Hall element 21 and the smoke detector 23 be connected with controller 22 that be arranged at the second other permanent magnet 20 of pin hole 330, arrange near the second permanent magnet 20.Second permanent magnet 20 is arranged on connecting rod 33 simultaneously, and Hall element is also fixedly installed on lock 31.Along with the rotation of connecting rod 33, the second permanent magnet 20 changes relative to the position of Hall element 21, thus Hall element 21 detects the position of pin hole 330 by the size of the field signal detecting position.Whether smoke detector 23 has smog to exist for detecting access control device place environment, thus whether detection has fire to occur, when there being fiery residence to occur, controller 22 sends signal control locking device 3 locking bolt 30 by receiving smoke detector 23 is opened automatically, for people run away passage easily, avoid cannot runing away because door lock closes.
Generally, the controller 22 of supervising device 2 is connected with Fingerprint Identification Unit 1, and controller 22 is connected with stepper motor 350 by motor-drive circuit 351 simultaneously.Controller 22 is electrically connected with electromagnet 341, for whether controlling the energising of electromagnet 341.
Principle of work of the present utility model: user squeezes into fingerprint, this fingerprint sends fingerprint matching pass signal after being verified by Fingerprint Identification Unit 1, first, in control lower electromagnet 341 power-off of the controller 22 of supervising device 2, spring-return original position is extended, and latch 340 is inserted in the pin hole 330 of connecting rod 33.Then, supervising device 2 receives signal that Fingerprint Identification Unit 1 sends and sends opened lock bolt signal (that is: starting stepper motor signal and stepper motor corner), start to rotate by the effect stepper motor 350 of motor-drive circuit 351, the gear set drive screw rod 34 that rotates through of stepper motor 350 rotates, at the rotation lower link 33 of screw rod 34, locking bolt 30 is pulled out in lockhole, back-moving spring 32 is forced to stretch, and door is opened.After stepper motor 350 worked for ten seconds, the controller 22 of supervising device 2 sends control signal and electromagnet 341 is energized, permanent magnet is adsorbed after electromagnet 341 is energized, latch 340 is rushed in pin hole 330 depart from, thus connecting rod 33 is released, back-moving spring 32 return shrinks, and locking bolt 30 is retracted original position, door automatic locking, for user provides convenience.After connecting rod 33 is released, under the control of the controller 22 of supervising device 2, stepper motor 350 reverses, and makes latch 340 go back to initial angle.When again needing to open locking bolt 30, owing to being provided with the second permanent magnet 20 on connecting rod 33, Hall element 21 detect the second permanent magnet 20 produce magnetic field size than and output voltage signal, controller 22 obtains the rotational angle of connecting rod 33 according to the voltage signal received, thus controller 22 calculates the deviation of pin hole 330 and latch 340 position, and send control signal and make screw rod 34 drive latch 340 to rotate to pin hole to correspond to position.After latch 340 forwards pin hole 330 correspondence position to, controller 22 sends control signal and makes electromagnet power-off, and latch 340 extends through pin hole 330, locking bolt 30 is entered and works next time.Before task again, carry out the contraposition again of latch 340 and pin hole 330, error when avoiding back-moving spring 32 to reset, avoid cannot carrying out to the work of unlatching again of locking bolt 30 because screw rod 34 and connecting rod 33 are not connected to position influence.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing the utility model instructions and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
