RFID Middleware's Study And Application Based On SOA

RFID (Radio Frequency Identification, RFID) is high technology which can acquisite information rapidly and real-timely and can treat information accurately, and RFID has broad application prospects in retail, logistics, transport, medical, defense and other fields. RFID middleware extends enterprise level middleware technology to the RFID domains and it is the the nerve center of various RFID industries applications.First,this thesis analyses and researches the components, the mechanisms and the advantages of many typical RFID middleware solutions.We presents a RFID middleware model which is on the basis of the thinking of SOA.The RFID middleware model is divided into Edge Server, information systems and data interface, each layer has specific functions and communication interfaces and layers are independent and collaborative.Then, the thesis elaborates the realation of RFID middleware which is related with Web Services and message queue. Edge Server includs such modules as RFID card reading and writing,the interface of reader,data checking ,sealing and sending message ; In the message system, we use object-oriented data-"Class" as message carrier to take out message merging,message classifing and message routeing; Data interface provides access interfaces for remoting applications with Web services ,and provides a stable and effective solution for information sharing between enterprises.Lastly, to solve a few issues of data acquisiting during the working procedures ,a set of of information gathering and managing system is presented with the RFID middleware which is developed in the thesis.This research specially obtains the Xi'an science and technology bureau information technology to fund (the project serial number:ZX06030).
