摘　　要：针对射频识别技术(RFID)应用技术中亟待解决的海量数据存储问题,提出了RFID路径数据的双编码压缩存储模型.该方法首先分离出RFID路径数据的位置信息和时间信息,采用一种改进的素数编码方法PrimeLabel对位置信息编码,每条路径的编码用该路径上的最后一个位置的编码来表示.其次使用一种新的区域编码(Durableregion based numbering,DRB)方法对时间信息编码,最后在此基础上设计了RFID路径数据的双编码存储模型.实验结果表明:此编码存储模型能更好存储压缩路径数据,且能更高效地满足RFID路径数据的各种查询需要.Concerning the problem of massive data storage in the RFID application fields, this paper proposed dual coding compression storage model for RFID path data. First, this model separated location infor mation and time information from RFID path data, took use of an improved prime number labeling named PrimeLabel to code location information,and the code of last location of the goods movement path was re garded as the path code. Secondly, a new regionbased numbering scheme（Durable region based numbering） was used to encode time information. And then a dual coding storage model for RFID path data was de vised. The experiment results show this dual coding storage model not only can store compression path in formation but also can meet the needs of various query of RFID data effectively.
