Radio Frequency Identification RFID (Radio Frequency Identification) is 21 the world's most high-tech development prospects and transformative , due to the maturity of the technology and the falling cost of RFID in a number of areas ( such as production , logistics , retail , transportation , pharmaceutical and other industries ) have a wide range of applications . Complex Event Processing CEP (Complex Event Processing) extracted for the first time as a real-time data analysis and event monitoring technology , composite information to the enterprises concerned or for corporate decision-making . Processing of complex event processing technology to RFID middleware , not only can greatly improve RFID middleware data processing capabilities , and can reduce the amount of RFID data storage , the massive RFID applications has had an extraordinary significance . The purpose of this project is to study a generic RFID complex event description language processing technology , the establishment of complex event processing models of computation and processing framework , integrated the existing laboratory RFID public service middleware to a service-oriented architecture platforms which provide complex event detection services for high-level enterprise applications . Description of complex event is an important part of a complex event processing technology , the current RFID complex event processing technology has been widespread concern and research , but less research and application of complex event description language paper in the basis of relevant studies on an XML-based RFID complex event description language , compared with the traditional complex event processing language , the language introduced instance space , the concept of detection mode, consumption patterns , with stronger skills scalability. In addition , the article describes the implementation details of a complex event processing engine , including engine architecture , data representation of complex events , and was a non-deterministic finite state automata (NFA) combined with matching tree complex event processing mode , complex event processing engine optimization strategy . Finally, we achieve a service-oriented framework , complex event processing engine integrated into the framework of the service , you can think that different users with different complex event detection service .
