Description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model circuit structure block diagram；
Fig. 3 is fingerprint identification module circuit diagram.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further details.
As depicted in figs. 1 and 2, USB flash disk of the present utility model includes that an open end is provided with the housing 2 of usb 1,
Be provided with housing 2 circuit board and with main control chip on circuit boards and storage chip are set, be provided with fingerprint on circuit boards
Identification module and voice cue module, additionally, being additionally provided with fingerprint collecting metal derby 4 and indicator lamp 3, the instruction in surface of shell
Lamp is two, respectively red led and green indicating lamp.
When using usually, user likes the fingerprint of certain finger of typing oneself in USB flash disk in advance according to personal habits,
During use, USB flash disk is connected into computer by usb 1 by user, by oneself corresponding finger print by 2 surface of housing
Fingerprint collecting metal derby 4 is contrasted with the fingerprint in USB flash disk, can open storage chip after completing matching.If it fails to match, language
Sound reminding module USB flash disk user's fingerprint matching can be pointed out unsuccessful or resurvey fingerprint or, now cannot just open USB flash disk
Storage chip.
This example also has fingerprint attendance function, as one embodiment of the present utility model, is additionally provided with the circuit board
Lithium battery power supply and signal are received and sending module, and the signal receives electric with fingerprint identification module and lithium respectively with sending module
Pond power supply is connected, and the signal receives and completes the reception of signal, processes and transmission with module is started, and completes function of registering.
The function concrete methods of realizing of registering of this example is as follows：
During roll-call, teacher presses the start button of signal generator, and student is in certain area（Classroom）It is interior to receive
Roll-call signal, then fingerprint of the fingerprint collecting metal derby 4 on USB flash disk by collection student, completes fingerprint matching, uploads a point concrete number
According to, during circuit turn-on, the green light of indicator lamp 3, when signal is registered in upload, the when red of indicator lamp 3 points out to have registered.U
It is that student is operated that fingerprint recognition on disk can be assisted in；Fingerprint attendance data can also be present in USB flash disk automatically,
Insertion computer can see the record of registering of oneself.
The signal generator and USB flash disk of this example is analogous to " mobile phone is with base station ", and they inherently have mutually biography
The function of news；Student everyone USB flash disk, teacher's also everyone signal generator, signal generator gather teacher's fingerprint in advance,
A fingerprint recognition is also carried out on signal generator, it is determined that being the signal of the operation transmission of teacher；The reality of function of registering
Now method is：
In view of a class size typically not over 1000 people, this example takes 10 2 system counting numbers to learn to each
Raw numbering, the signal receiving module of USB flash disk after the signal that signal generator sends is received, before confirming to have passed through fingerprint recognition
Put, the signal of USB flash disk is received and can feed back a signal with sending module, and such as No. 1 is just returned " 0000000001 ", and No. 1023 just
Feedback " 1111111111 ".
As another embodiment of the present utility model, by the signal send button on shell 2, the fingerprint collecting
Part is arranged in the signal send button, the signal send button respectively with main control chip and by fingerprint identification module with
Signal is received and is connected with sending module.When needing to register, by pressing signal send button, circuit turn-on is completed, so as to complete
Reception, fingerprint collecting and process and the transmission of signal of registering into signal.During circuit turn-on, the green light of indicator lamp 3 works as upload
Register signal when, the when red of indicator lamp 3, point out registered.
Additionally, in order to be further ensured that the accuracy registered, reload temperature sensor, the temperature are gone back on the circuit board of this example
Degree sensor is connected with fingerprint identification module, and when signal send button is pressed, the temperature sensor passes through body warming
Know the whole circuit of activation, realize collection, storage and the transmission of fingerprint.
