Embodiment
Below with reference to accompanying drawing, elaboration is further given to the utility model.
Refer to Fig. 1, accompanying drawing 1 is the circuit structure block diagram of the finger hand vein recognition smart lock of the utility model band acquisition window illumination instruction, and it comprises: a Master control chip 1, this Master control chip 1 is for controlling the storage of finger print information, finger print information identification, unblanks to start control, and warning reminding etc.One vein module 2, this vein module is connected with described Master control chip 1 by serial communication interface.One acquisition window lighting pilot lamp 3, this acquisition window lighting pilot lamp 3 is connected to the general I/O port of described Master control chip 1, and this acquisition window lighting pilot lamp 3 is controlled by described Master control chip 1.One slip lid detection circuit 4, this slip lid control circuit 4 is connected to described Master control chip 1; One keyboard circuit 5, this keyboard circuit is connected to described Master control chip 1 equally; The motor drive circuit 7 that one operates relevant information for showing, the display panel module 6, of recognition result information controls lock core action.And sound out-put circuit 8 and a pilot lamp 9.
In more detail, described finger vein module 2 is electrically connected with Master control chip 1 by serial communication interface, and Master control chip 1 is controlled by specific instruction finger vein module 2, operates and obtain data.Wherein, refer to that venous collection, storage, comparison all complete in finger vein module 2.Comprising, first, the access information acquisition of user, then, this refers to that vein module 2 stores gathered information, as the comparative information storehouse identified later.When user inputs identifying information again, this refers to that vein module 2 completes the comparison of information automatically, thus draws to the feedback signal of Master control chip 1 one respective action.Refer to that vein module 2 issues Master control chip 1 comparison result by serial communication interface, Master control chip 1 is according to the comparison result information received.Show corresponding information by the display panel module 6 be connected with Master control chip 1, meanwhile drive the sound out-put circuit 8 be connected with Master control chip 1 and pilot lamp 9 to send acousto-optic hint.When referring to the success of vein comparison, Master control chip 1 sends unlocking signal to the motor drive circuit 7 be attached thereto, and motor drive circuit 7 receives unlocking signal rear drive motor and performs unlocking action.
Refer to accompanying drawing 2 to accompanying drawing 4, wherein accompanying drawing 2 locks the locking face structure schematic diagram installed for above-mentioned Intelligent Recognition, and the slip lid that accompanying drawing 3 and accompanying drawing 4 are respectively smart lock locking face is in the side sectional view of closing and opening two states.This smart lock face comprises, locking face 10 before, is installed on the finger vein module 2 on described front locking face 10, is installed on the finger venous collection window lighting pilot lamp 3 on front locking face 10, and is slidably installed on the slip lid 11 on described front locking face 10.Further, described finger vein module 2 and acquisition window lighting pilot lamp 3 are installed in the shrinkage pool on described front locking face 10, and described acquisition window lighting pilot lamp 3 is installed on the top of described finger vein module 2.The finger venous collection window of described finger vein module 2 is skewed.
Refer to accompanying drawing 3, when slip lid is in closed condition, slip lid 11 can cover and refer to venous collection window, and adopt edge snapping between wherein said slip lid 11 and front locking face 10, can slide up and down mounting structure.Refer to that vein module 2 is due to the protection of slip lid 11, can avoid being accidentally impacted, simultaneously can be dust-proof, finger vein module is referred to, and venous collection window keeps clean.When under slip lid 11 closure state, the permanent magnet 12 be fixed on slip lid 11 is positioned at above the slip lid detection circuit 4 of use magnet-sensitive switch device realization, and described slip lid detection circuit 4 is a magnetic induction control circuit.Described magnet-sensitive switch device comprises tongue tube, hall device etc.Described slip lid detection circuit 4 is in closed condition or opening for detecting slip lid.The signal detected is delivered to master control coremaking 1 input port by described slip lid detection circuit 4, when Master control chip 1 input port inquire slip lid detection circuit 4 be in predetermined level state time, described Master control chip enters periodic queries slip lid detection circuit state model, operational motion can have been known whether by inquiry slip lid detection circuit state, unlatching is not needed to refer to intravenous sensor under this pattern, and only after slip lid is unlocked just open refer to intravenous sensor, realize low-power consumption standby.
Refer to accompanying drawing 4, under described slip lid 11 is in opening, permanent magnet 12 is away from the top of slip lid detection circuit 4, thus make permanent magnet 12 be in outside its detection sensor scope, slip lid detection circuit 4 exports the logic level contrary with under slip lid 11 closure state, when Master control chip 1 input port scans this level state, export control signal, light and refer to intravenous set window lighting pilot lamp 3, user can clearly be observed and refers to venous collection window situation, be convenient to fast finger is placed into assigned address, open simultaneously and refer to vein module 2, make finger vein module 2 in running order, wait for that user puts into finger.When referring to that vein module 2 detects the finger that user puts into, refer to venous collection window lighting pilot lamp 3 and then start collection refer to venous information by first closing to Master control chip 1 instruction, avoid referring to that the impact of venous collection window lighting pilot lamp refers to venous collection effect, also reach saves energy object simultaneously, as referred to venous information collection failure, then Master control chip controls to refer to that venous collection window lighting pilot lamp is lighted again, and reminding user adjustment finger position and attitude, until gather successfully.The finger venous information collected carries out buffer memory according to the instruction of Master control chip 1 in finger vein module 2, compare peering, refer to that vein module 2 issues Master control chip 1 comparison result by serial communication interface, Master control chip 1 is according to the comparison result information received, corresponding information is shown by the display panel module 6 be connected with Master control chip 1, send acousto-optic hint by the sound out-put circuit 8 that is connected with Master control chip 1 and pilot lamp 9 simultaneously, when referring to the success of vein comparison, Master control chip 1 also sends unlocking signal to the motor drive circuit 7 be attached thereto, motor drive circuit 7 receives unlocking signal rear drive motor and performs unlocking action.
In sum, the finger hand vein recognition smart lock of the utility model band acquisition window illumination instruction, while waking reduction power consumption up by slip lid, slip lid also can prevent from referring to that vein module suffers abnormal shock to a certain extent, dust-proof.Display screen display relevant information, go back acousto-optic prompting, more convenient operation is directly perceived, more energy-conservation simultaneously.After slip lid is opened, refer to that venous collection window lighting pilot lamp user can clearly be observed and refers to venous collection window situation by lighting, when gathering unsuccessfully, control to refer to that venous collection window lighting pilot lamp is lighted again by Master control chip, reminding user adjustment finger position and attitude, be convenient to user and fast finger be placed into assigned address, improve collecting efficiency.
