Event-Driven RFID System Development for Retailer Supermarket

RFID system´s event processing ability immediate influence to entire RFID system´s operating efficiency. This article designs the model and frame of event-driven RFID system, and defines the RFID event. Based on this, designs the filtering mechanism and complex event matching processing strategy based on the Hash table, can realize real-time analysis and processing of the RFID data, and provided the basis for the high-level application. By developing the simulative retailer supermarket management system, the rationality of design and the accuracy of algorithm are proved.
