Abstract: To automatically and accurately obtain the concrete physical world data in real-time circumstance, the idea of real-time enterprise based on smart items technologies (Radio Frequency IDentification(RFID), Wireless sensor networks) was put forward. The application scenarios of smart items in manufacturing enterprise were provided. It could not only provide new data sources for existing information systems, but also improve the business processes to some extent. The system hierarchy architecture and its key research trends were described in detail. The event-based middleware was the critical to system integration. Hierarchy and functionalities of the middleware were analyzed in particular. The application in some enterprises showed that smart items technologies were effective to integrate the physical world with information system.

Key words: smart items, radio frequency identification, wireless sensor networks, event-based middleware, information systems of manufacturing enterprise
