The Realization Of Hardware And Software Of DSP Fingerprint Technology

In the work of student management in higher vocational colleges,the fingerprint management system can play a positive role,although currently on the market there are corresponding products can buy,but to lead the Vocational College Students'development of fingerprint management system,and application of DSP chip TM S320C5402 processor as the core of the design of the fingerprint management system,can fully meet the students' management needs,with important theoretical significance and practical value.Firstly,the advantages of the fingerprint technology in a variety of biometric identification technology,and based on the in-depth study of DSP technology and application,determine the overall design scheme based on DSP fingerprint technology.Under the comprehensive consideration of the current technology of expansion,performance and cost factors,reference to the relevant academic papers,the design report data from recent years design a based on TI company DSP chip TM S320C5402 processor as the core of the fingerprint identification system,in order to achieve a low cost,and easy to upgrade the development,application and operation simple.Secondly on fingerprint identification system hardware circuit design and software algorithm realization are described,with TM S320C5402 processor as the core,using FPS200 fingerprint sensor to complete fingerprint acquisition,the software using C programming language to complete the fingerprint image collection and processing,the VB language to achieve software interface.This paper mainly introduces the selection of DSP,the characteristics of fingerprint identification sensor,the design method of fingerprint software and the method of budget processing in every link..Finally,through the software and hardware settings,the background interface realizes the fingerprint management system and applied to the students management in higher vocational colleges..After debugging,the system collected high efficiency of fingerprint,the fingerprint comparison to achieve identification is less time consuming and processing data is accurate and reliable,in a very short period of time to complete the target fingerprint matching,fast and accurate records to collect information,the whole system in theoretical research and practical application of most broad prospects.
