Examination Management Fingerprint Identification System

With the development of the society at a high speed,the management level of the examination has continued to be improved.Base on the fingerprints is unique,the fingerprints identification method is becoming a very useful personal identification method.Besides,the short distance wireless transmission has also widely been used in sorts of data transmission system which is characterized by quickness,accuracy.In this article,using both of the advanced technologies above,an automatic personal system of the examination management using fingerprints was designed.Make sure the system examination system more and more fairly and justly.The article make a detailed design,mainly including the hardware circuit,data Transfer Protocol,software Computer monitored system,data encryption arithmetic and CRC checking algorism.Using the SM-L62 fingerprint recognition module was selected to finish the fingerprints getting and comparing,and other functions of personal identification.Selecting the NRF24L01 to complete the data wireless transmission,the hand-set can wirelessly connect to the centery workplace,meanwhile the centery data-workplace can download the fundamental information and examination public information by wireless transmission,and some information of the examination and cheating also can be recorded.Finally,candidates messages will be send to the centery workplace,and establish a real test for the wireless transmission network of the whole system refering to the FDMA communion theory.All make sure the trait of the system is rapid and steady.To make maximum use of the system resources of PC, adopt the Visual Basic6.0 to exploit the visual operation software parts of the Computer monitored system which can collect fingerprints information, invoking the API function of the SM-L62.At last,check the function of the whole system.The main features of system were as follows:easily to use,conveniently to maintenance and has a large realistic meaning.
