RFID（無線射頻識別，Radio Frequency Identification）是一種自動識別技術，通過無線射頻方式進行非接觸雙向數(shù)據(jù)通信從而對目標加以識別。由于直接從RFID 閱讀器獲取電子標簽上的EPC 數(shù)據(jù)會產(chǎn)生大量的冗余數(shù)據(jù)，且這些數(shù)據(jù)不能被應用程序直接使用，
同時必須考慮與各種閱讀器的兼容。本文基于EPCglobal ALE1.0 標準提出了RFID 數(shù)據(jù)采集中間件，通過對原始標簽數(shù)據(jù)進行處理生成ALE 事件數(shù)據(jù)，實現(xiàn)對冗余數(shù)據(jù)的過濾和整合，通過中間件中的硬件適配器和邏輯閱讀器配置實現(xiàn)對各種硬件設施的靈活兼容。本文最后研究了基于RFID 數(shù)據(jù)采集中間件的倉庫管理系統(tǒng)。

Research of the RFID ALE Server Middleware

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.
