Design And Implementation Of Data Management Module In Embedded RFID Middleware

Radio Frequency Identification (RFID) is a technology that can identify objects automatically and acquire relevant information through radio frequency signals. As the rapid development of the technology, RFID expands its domains and finds wide application in our daily life. It will be a basic technology in the construction of information society in future. RFID middleware's functions include three facets. First, controlling the working modes of RFID readers according to concerted ways and assuring different reader facilities working in phase. Second, filtering most of redundant data according to some rules, and sending available data to the back information system. Third, communicating RFID readers and enterprise distributed application platforms.The author develop data management module of the embedded RFID middleware. The work includes the parsing of data from RFID readers, the setting of filtering rules, the storing of data and how to control those functions through Web.This thesis introduces the frame of embedded RFID middleware and analyzes the data management module. The main work includes constructing embedded database and embedded WEB on ARM developing board through cross compiling, picking RFID tag information by parsing the data from RFID readers, storing the data after filtering in the embedded database and offering the data to users through embedded WEB. By combination of the technology of RFID middleware and embedded Linux, the author builds an embedded RFID middleware. It will be a good help to widely usage of RFID middleware.
