Description
Technical field
The utility model relates to a kind of mobile memory medium, especially a kind of USB flash disk having a display function.
Background technique
The fingerprint recognition USB flash disk with liquid crystal display is roughly divided into two kinds currently on the market, needs to be inserted into calculating one is USB flash disk
Machine provides power supply by computer, and completes the related algorithm of fingerprint recognition by the processor of computer, realizes that fingerprint is recognized
Card；Another kind is can to realize fingerprint recognition in offline state, and realization principle is to increase independent power supply in the inside of USB flash disk
And processor greatly increases the cost of USB flash disk although the fingerprint recognition under realizing off-line state.
The fingerprint recognition USB flash disk of above two type there are the drawbacks of be: when multiple USB flash disks occur and storing together, USB flash disk is held
The person of having needs to open power supply one by one, and the USB flash disk of oneself is distinguished by the display content on liquid crystal display, troublesome in poeration, convenient
Property is low.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides that a kind of structure is simple, production cost is low, can accomplish
The fingerprint recognition USB flash disk of the novel electron paper of rapid identification USB flash disk.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of fingerprint recognition USB flash disk of novel electron paper, including shell are provided with USB interface, the shell on the shell
It is inside provided with Central Control Module, fingerprint identification module, data memory module and electronic paper display module, the center controls mould
The input terminal of block is electrically connected with the USB interface, the output end of the Central Control Module respectively with the fingerprint identification module,
Data memory module and the electrical connection of electronic paper display module, the electronic paper display module includes driving plate and electronic paper display
Screen, the input terminal of the driving plate is electrically connected with the output end of the Central Control Module, the driving plate output end with it is described
The surface of the shell is arranged in electronic-paper display screen electrical connection, the electronic-paper display screen.
The fingerprint identification module includes fingerprint recognition chip and fingerprint identification region, the fingerprint recognition chip with it is described
Central Control Module electrical connection, the fingerprint identification region are arranged on the electronic-paper display screen.
The Central Control Module includes MCU processing chip.
The data memory module includes FLASH memory.
The beneficial effects of the utility model are: the utility model can be by electronic-paper display screen come in customized setting display
Hold, and display can still be maintained in screen after disconnecting power supply, people can pass through the U of content rapid identification oneself shown above
Disk avoids the trouble for finding USB flash disk, has many advantages, such as that structure is simple, production cost is low, easy to use.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is one of structural schematic diagram of the utility model；
Fig. 2 is the second structural representation of the utility model.
Specific embodiment
Referring to Fig.1, Fig. 2, a kind of fingerprint recognition USB flash disk of novel electron paper, including shell 1 are provided on the shell 1
It is aobvious to be provided with Central Control Module 3, fingerprint identification module 4, data memory module 5 and Electronic Paper in the shell 1 for USB interface 2
Show module 6, the input terminal of the Central Control Module 3 is electrically connected with the USB interface 2, the output of the Central Control Module 3
End is electrically connected with the fingerprint identification module 4, data memory module 5 and electronic paper display module 6 respectively, the electronic paper display
Module 6 includes driving plate 7 and electronic-paper display screen 8, the output of the input terminal of the driving plate 7 and the Central Control Module 3
End electrical connection, 7 output end of driving plate are electrically connected with the electronic-paper display screen 8, and the electronic-paper display screen 8 is arranged in institute
State the surface of shell 1；In the present embodiment, the USB interface 2 can be connect with computer 9, be mentioned for the modules in the shell 1
Power supply source；And realize the interaction of data between computer 9 and USB flash disk.
The fingerprint identification module 4 includes fingerprint recognition chip and fingerprint identification region, the fingerprint recognition chip and institute
The electrical connection of Central Control Module 3 is stated, the fingerprint identification region (capacitance type fingerprint identification) is arranged in the electronic-paper display screen 8
On, in the present embodiment, the model PS1802 of the fingerprint recognition chip has many advantages, such as high-performance, low-power consumption, the fingerprint
Identification module 4 can effectively prevent the significant data in USB flash disk to be stolen by other people, preferably protect the privacy of people；The center
Control module 3 includes that MCU handles chip, in the present embodiment, using STM32 series monolithic as MCU processing chip, is had
The advantages that controlling high precision, control simple, cheap and long service life.
In the present embodiment, the data memory module 5 includes FLASH memory, specifically, the FLASH memory packet
Public memory space and encryption memory space are included, in no progress fingerprint recognition, the public memory space can only be used, only
Have by the way that the encryption memory space after fingerprint recognition, could be used.
In the present embodiment, the electronic-paper display screen 8 is EINK display screen, has many advantages, such as easily manufacture and low-power consumption,
After fingerprint recognition, the display content of EINK display screen can be defined using computer end drive software, and is kept when power is off
