Based On The Rfid Middleware

RFID or radio frequency identification technology is a highly efficient data collection and identification technology. Widely used in logistics, transport information health care retail and other industries, could significantly enhance the management and operational efficiency and lower costs. With the formal release of RFID White Paper, China will celebrate the climax of RFID applications.RFID applications system is made up of several components such as RFID tags RFID readers and application software etc . Along with the continuous deepening of RFID applications, application system faces many problems, such as the problem of equipment incompatible the problem of data preprocessing, the problem of data security , which are discussed in this paper, which prevent the RFID technology . RFID Middleware as the core technology, plays a very important role when RFID systems will be deployed in reality. Its main task is to filter aggregation release date which is relevant to tags coming from readers, to reduce the massive amount of raw data which is transmitted from readers to application system , to increase the abstract meaningful information. It decreases the complexity of the enterprise information system reform improves the accuracy of data collection and enhance the security of data access. It establishes a strong message bridge between RFID equipment and application systems.At present, domestic and international research has been done on the RFID middleware, but which still is the trial stage, rarely have mature products which are more or less restricted and have shortage, the paper put forward RFID middleware system framework which is made up of the data collection layer data process layer information distribution layer. This paper has also done a lot of research and exploration on the design and implementation of RFID middleware , and do a lot of work in some key technologies such as middleware technology virtual storage space technology In-memory database technology and data distribution technology. It also give a preliminary design model and realization of the RFID middleware at the end.
