Embodiment
In Fig. 1, Fig. 2, this practicality relates to a kind of electronic identification, more specifically to a kind of electronic identification harvester, comprising acquisition module I, PC holds I, server, PC to hold II and acquisition module II, for the collection of the valid certificates data of electronic identification file, the validity of electronic identification, uniqueness and confidentiality can be guaranteed.
Acquisition module I and acquisition module II is made up of fingerprint sensor, analog to digital converter, single-chip microcomputer, touch screen, touch chip and RS232 interface.Touch screen provides operation interface and is transferred out by the touching signals collected.Touch chip is used for measuring voltage electrode, compares, and can carry out analog/digital conversion and D/A switch in inside to signal to the position coordinates of touch point.The touch chip that touch chip selects Texas Instrument to produce, its model is ADS7846.When using acquisition module I or acquisition module II to carry out fingerprint typing, transfer the interface for password input on touch screen, touch screen inputs proper password, code signal is transferred to single-chip microcomputer by touch screen, single-chip microcomputer is compared successfully to password, could carry out identifying to the input signal of fingerprint sensor and process.
Fingerprint sensor transmits for identifying fingerprint signal and fingerprint signal being converted into current signal.The fingerprint sensor that fingerprint sensor selects Tu Zheng Science and Technology Ltd. to produce, its model is TS1012.TS1012 collects the crestal line signal of fingerprint and valley line signal and to the corresponding electric current of generation, TS1012 inside containing amplifying circuit, and then is amplified the electric current of transmission, thus improves the transmission quality of fingerprint image.
Analog to digital converter is used for that simulating signal is converted into digital signal to be transmitted.The analog to digital converter that analog to digital converter selects Ya De promise Semiconductor Co., Ltd to produce, its model is AD9637.AD9637 is a kind of high precision, high-speed signal acquisition and modular converter, thus ensure that accuracy and the rapidity of signal typing.AD9637 is converted into digital data transmission to single-chip microcomputer after receiving the signal collected and process.
Single-chip microcomputer Received signal strength also exports steering order after processing signal.RS232 interface is used as single-chip microcomputer and peripheral data transmission channel.Single-chip microcomputer select Philips Radio&Video Co. to produce single-chip microcomputer, its model is 80C552.80C552 receives fingerprint signal and also carries out pre-service to fingerprint signal, and fingerprint signal is converted into matrix form and transfers to PC by RS232 interface and hold I.The time of fingerprint signal collection is sent to PC and holds I by single-chip microcomputer simultaneously.
