Description
Technical field
The invention belongs to computer equipment technical fields, and in particular to be a kind of double subregion USB flash disks.
Background technique
Existing product function is single, and a USB flash disk can only be used in a kind of occasion, security performance, and privacy is imperfect.Body
Product is small to be easily lost.The USB flash disk loss of unencryption can cause privacy leakage, and oneself also can be due to the loss of significant data very
Puzzlement.Service life and data safety issue, and easy squeeze because easy to carry, drop and cause loss of data.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, provide a kind of double subregion USB flash disks, the subregion have it is easy to operate,
The characteristics of differentiated control, design are simplified, efficient ST processor, software and hardware perfect combination a, plate is pulled entirely.
In order to solve the above technical problem, the present invention provides following technical schemes：
A kind of double subregion USB flash disks, including USB flash disk ontology 1 are provided with master switch 2, No.1 switch 3, two switches on USB flash disk ontology 1
4, master switch is unlocked by fingerprint master switch, is used to complete unlatching, setting, registration, deletion and emptying step operation；USB flash disk ontology 1,
Including pcb board, main control chip 5, crystal oscillator, capacitance-resistance capacitor, USB interface 6, two flash chips 8, sensor, it is equipped on pcb board
Main control chip 5, crystal oscillator, capacitance-resistance capacitor, USB interface, two flash chips, sensors.
Preferably, USB flash disk ontology 1, further includes fingerprint identification module, patch 6*6*5 microswitch 7, and fingerprint identification module connects
Unlocked by fingerprint master switch is connect, a patch 6*6*5 microswitch connects No.1 switch, another patch 6*6*5 microswitch connection two
Number switch.
Preferably, main control chip is STM32F205RC import ST advanced digital processor, input time<0.1 second.
Preferably, sensor is infrared optics fingerprint collecting head, comparison time<0.1 second.
Preferably, flash chip (FLASH) fingerprint capacity is 8 pieces.
Compared with prior art, the present invention has following beneficial effect：
Product of the present invention is master switch (unlocked by fingerprint) respectively in three keys of increase in appearance of common U disk, remaining
Two switches are two changeable subregions；One is used in life, and one is used work, and life and work is neglected neither, encryption function
Completely.Design is simplified：Efficient ST processor, software and hardware perfect combination, a plate are pulled entirely.It is easy to operate：Human oriented design is grasped step by step
Control, unavoidably maloperation.Algorithm is advanced：Optimize image procossing, creates high-precision effect fingerprint identification technology.Differentiated control：Administrator (3
Piece) with read-write capability control (5 pieces) of ordinary user have look facility.Three key operations：It completes to open, setting, registration, delete
With empty (this step carries out in individual program bag).Stablize anti-interference：Circuit uses the anti-external electromagnetic interference of low frequency designs.
