RFID 数据采集中间件研究

RFID（无线射频识别，Radio Frequency Identification）是一种自动识别技术，通过无线射频方式进行非接触双向数据通信从而对目标加以识别。由于直接从RFID 阅读器获取电子标签上的EPC 数据会产生大量的冗余数据，且这些数据不能被应用程序直接使用，
同时必须考虑与各种阅读器的兼容。本文基于EPCglobal ALE1.0 标准提出了RFID 数据采集中间件，通过对原始标签数据进行处理生成ALE 事件数据，实现对冗余数据的过滤和整合，通过中间件中的硬件适配器和逻辑阅读器配置实现对各种硬件设施的灵活兼容。本文最后研究了基于RFID 数据采集中间件的仓库管理系统。

Abstract: RFID(Radio Frequency Identification) is an automatic identification technology which identifies object via non-touching dual-directional data communication by using radio frequency technique. If the application uses the RFID reader to acquire the data from the RFID tags, it will face a lot of EPC data which would be redundant and couldn't be used, by the way, the application have to create many interfaces for different RFID hardware. This paper proposes a RFID ALE server middleware based on the standards of EPCglobal ALE1.0, which will filtrate and aggregate the raw EPC data into demanded ALE data, and support different RFID hardware by the hardware adapter within this middleware and the logic readers' configuration. At last, the application of this middleware in the warehouse management system was given as an example.
