REAL-TIME MASS OF EVENTS FUSION BASED ON COMPLEX EVENT PROCESSING IN RFID- BASED MANUFACTURE SYSTEM

摘要

RFID technologies are widely used to collect information to support control and optimization of production implementations in manufacture enterprise. RFID devices continually report mass of data to manufacture system. How to collect and integrate big data from RFID devices is a key problem to popularize RFID technologies. Most existing researches focused on realtime data sensing techniques, but real-time data integration is rarely discussed. Mass of data and time constraints lead to challenges for information integration. In this paper, we present an architecture of RFID-based manufacture system. In order to solve the problem of information integration, as a core component of the manufacture system, an information integration framework based on complex event processing is proposed. Some key techniques are developed, including specification of events, a high-performance algorithm for events fusion, and a method that guarantee events fusion satisfy time constraints. A prototype system is developed, and experiments indicate that the architecture is feasible.
