The Study And Application Of Data-collection And Data Processing Based On ISO15693 Technology

Auto-ID System applies some identification instruments to collect the information of objects,and then provides this information to background computer systems for further processing.Auto-ID technology has been developing rapidly all over the world and it has been playing a key role in many fields.Among the various Auto-ID technologies,RFID technology is the most promising one because of its security,reliability and high collecting speed.With the development of technology and science,the cost of RF hardware decreases continuously,and the applying edge of RFID technology is more and more manifest.In the 21st Century,RFID technology will be the mainstream of Auto-ID.Generally,RFID System consists of hardware instruments,such as RF reader,antenna,transponder,and software components such as data collecting and processing Middleware.In this thesis we study the structure and working principle of components constituting RFID system detailedly and systematically,and play emphasis on the study of data-collection middleware.Data-collection middleware is a very complicated sub-system,which includes data filtering and management,reader coordination,data routing and integration,process management,data security management,outer interface,etc.In this thesis,using STU650A reader,Tag-it HF-I transponder and software Jbuilder9.0,Visual C++6.0,SQL Server,we build up a complete RFID system.In this real system,based on the principle of data-collection middleware,we realize a data-collection module,which has some functions such as reader management,data adapting,data filtering,data queuing and so on.Finally,through path-tracing system and family-school communication system,we show that RFID technology can be applied in many different fields.In these two systems, we encode for each object,and then write these codes into transponder,so the data represent the actual product or student.We focus on the discussion of data processing and application in these systems and show the advantages of RFID technology and accumulate precious experience for the further development of RFID.
