RFID复杂事件处理关键技术的研究与改进

摘要

RFID复杂事件处理是一个新兴的技术领域,它用来处理大量的简单事件,并从中整理出有价值的事件.RFID事件和传统的事件相比较具有海量性、空间性和时间性、数据不准确性等特征.文中在分析REID数据特点的基础上,对RFID复杂事件处理的关键技术进行研究和改进,主要介绍RFID数据的清洗和事件检测技术.对于RFID数据清洗部分,提出了多层次过滤的方法使得到的数据更接近真实情况,而事件检测方面则提出了局部检测和全局检测相结合的方法对相关数据进行检测以得到更有意义的数据供上层应用使用.最后,对RFID复杂事件处理的发展趋势做出展望.%RFID complex event processing is an emerging technology to handle a large number of simple events and sort out the valuable events. Compared to the traditional events,RFID events have the following characteristics:large volume,temporality and spatiality,inaccuracy etc. Based on the analysis of toe characteristics of RFID data,research and improve the key technology of RFID complex event processing,focus on RFID data cleaning technology and event detection technology. For the RFID data cleaning,a multi-level filtering approach,which can obtain data closer to the real situation,has been proposed. And for event detection,local detection and global detection has been combined to get more meaningful data for the upper application. Finally, give an outlook of development trend of RFID complex event processing.
