RFID middleware system, as the nerve center of many RFID systems, is being more and more concerned on by the people. It plays a key role in the development of the entire RFID industry. Firstly, this paper briefly introduces the present situation of RFID middleware, and then focuses on data filtering, data aggregation and information transmission three important technologies. According to the function demand, the next section introduces the hierarchical design idea for RFID middleware system. Based on the layered design idea, we construct a hierarchy structure of RFID middleware and present a kind of enterprise class applied model, in which RFID event manager module is responsible for processing data streams and RFID information service module is responsible for system integration. This applied model is easy to build a new RFID middleware system provides a kind of reference. Simulation and practical tests prove that the middleware system can real-time reads the important information of tracked objects such as goods in storehouse, achieve a more efficient management and facilitate practical application for Internet of things technology.
