Abstract


With the depth of the RFID applications, the deployment of the RFID system gradually to the trend of large-scale network distributed development, conventional data processing system can not meet the demand for such data processing how to handle the collection from the distribution on the network a plurality of reader Massive RFID data has become a key issue in the application of RFID Enterprise article in the Shanghai Jiaotong University reconfigurable RFID middleware architecture and design of a data processing module, obtained from the network of distributed reader massive redundancy random sequence of the data after the processing of the module, into the upper complex event processing module needs cleaning data data redundancy filtering, data smoothing, and a real-time database for RFID applications designed together form the data processing module wherein , data redundancy two different filtering mechanisms designed for different business, a real-time redundancy filtering mechanism out of order for the real-time requirements of the application design, and the other is for the tab order demanding applications delay redundant filtering mechanism design of the full sequence, two ways to complement each other, increase data redundancy filter smoothing effect data from three dimensions to guarantee the integrity of the data the first time smoothing compensation from the time dimension reader Read loss; Secondly, the spatial smoothing the use of the space of the reader is arranged for complementary, thereby avoiding leakage reading of the tags; Finally, data integrity constraints between different reader is on the same logic from the business logic definition of compensation rules, and to achieve the reader dynamic binding with complementary real-time memory database is designed according to the RFID data features a streamlined but efficient dedicated data storage model, we learn from the T-tree structure for the database design of the TT index structure, which effectively improve the real-time data processing efficiency, and provide a buffer mechanism Firstly RFID data processing technology review, discuss current RFID data processing technology for the further use of the data, analysis and comparison of the major companies in RFID data processing solutions and common international norms; Secondly, summed up the needs and the problems of the RFID reader management; then RFID data cleaning algorithms and real-time memory database; described adapt RFID network applications data processing architecture and its implementation method
