Description
Technical field
This utility model belongs to the fingerprint comparison work attendance electronic product in living things feature recognition field.
Background technology
The development of work attendance series products has successively produced the three generation products form so far, it at first is the paper tape telltale clock, the IC-card telltale clock has appearred again then, this two pratices fraud after diligent series products comes out, once unusually fiery, but develop into the later stage, and situation is serious, consumable quantity is huge, card is damaged to lose or forget these drawbacks easily and constantly occurred owing to replace checking card, a lot of people are disappointed gradually to this two diligent product of praticing fraud, and third generation work attendance product---fingerprint attendance at this moment occurred.
Since the fingerprint attendance product comes out, the branch of put it briefly online fingerprint attendance system and off-line fingerprint attendance recorder the product of variform successively appearred.The two is compared, and the advantage of off-line fingerprint attendance recorder is more obvious, and it is more flexible than the former, need not take PC during normal operation in normal, saves resource, is easy to safeguard.
Summary of the invention
The purpose of this utility model is exactly to utilize characteristics of human body's fingerprint to come unique identity of checking personnel individuality, and notes the detail time of each checking, proves to do work attendance.Fingerprint one is pressed, and gets final product work attendance, needn't worry to leave behind card, forget worries such as password, and is easy to use.
This utility model realizes by the following method: the archives that come a newly-built employee earlier with the Chinese character coding input method in the embedded system, gather finger print image by the CMOS fingerprint capturer then, through the USB main control chip fingerprint image is transferred to embedded type CPU, embedded type CPU extracts feature to the fingerprint image of gathering, and is stored in the Employee Profile.When work attendance, existing fingerprint is compared in fingerprint image that fingerprint capturer is collected and the storer, find out the pairing job number of fingerprint, the more pairing Chinese Name of this job number is presented on the liquid crystal display, utilize speech synthesis technique that Chinese Name is reported out simultaneously.When statistics, can checking-in result be sent on the USB flash disk by the USB interface on the telltale clock, also can pass through RS232 standard serial port line or CF Ethernet card and compunication, can also on telltale clock, directly browse attendance record, simple statistics attendance record, print attendance record.
Technical essential of the present utility model is: as shown in Figure 1, the work attendance mode has three kinds, if user's work attendance that accesses to your password, just the password that directly enters cryptographic libraries and job number counterpart personnel according to " 1, password " among Fig. 1 is compared.If the user uses fingerprint comparison, judge whether to import job number earlier.If "No", program will directly enter fingerprint collecting and begin 1 according to " 2, directly by fingerprint " among Fig. 1: the N comparison; If "Yes", program will further judge it is the input packet number then according to " 3, Enter Number " among Fig. 1, still import job number, if packet number, program will enter fingerprint collecting and carry out 1 according to " 4, packet number " among Fig. 1: the G comparison, if job number, program will enter fingerprint collecting and carry out comparison in 1: 1 according to " 5, member's job number " among Fig. 1.The time keeping of after comparison finishes the employee press fingerprint and then is got back to the fingerprint attendance place and is waited for work attendance next time in writing down the storehouse.
The principal feature of this utility model and effect are: can be directly on this product directly the input Chinese Name, directly carry out work attendance, phonetic synthesis, directly on machine, browse and add up and print attendance data, can carry out characteristics such as exchanges data in several ways with fingerprint.Solved code name in the off-line fingerprint work attendance product unclear, obscure easily, the problem of data transmission trouble, statistics confusion, be very easy to the attendance management personnel and add up.
