網路服務技術建置射頻識別相容的海鱺產銷履歷系統

Abstract

隨著越來越多的國際標準諸如HACCP、ISO 22000等的問世，食品追溯系統成為食品供應鏈中監控食品安全的有用工具。本研究提出使用網路服務技術以建構射頻識別相容的海鱺追溯系統。在這項新方法的架構下，以網路為基礎的追溯系統包含了服務提供者，服務仲介者以及服務需求者。由操作觀點而言，每個服務提供者利用網路服務描述語言文件發送本身的服務規格到通用描述、探索與整合仲介端註冊。每當服務需求者請求服務追溯一項食品的安全紀錄時，這項請求會將簡單物件存取協定為基礎的條碼或射頻識別標籤信息透過網際網路送到服務仲介端。接著服務仲介端會回應相對應的網路服務描述語言文件，將此請求轉傳到該項服務提供者以提供更多食品安全資訊的細節內容。進一步而言，有兩項主要的軟體成果已經達成。其一是稱為工作日誌的專用軟體系統，此系統實作於供應端，用以顯示如何扮演服務提供者的角色，例如蒐集食品安全相關資料，傳送網路服務描述語言文件等。另一項是附加條碼以及射頻識別介面的使用者友善介面的入口，此入口被用來展示服務需求端與服務仲介端之間的資訊互動。

Since the advent of more and more international standards such as HACCP, ISO 22000, etc, food traceability system becomes a useful management tool for monitoring food safety in food supply chains. In this thesis, web services technology has been proposed for constructing a RFID-compatible traceability system for cobia. Within the new approach, the web-based traceability system essentially consists of service providers, services brokers, and service requesters. From an operational viewpoint, each service provider submits its own service specification through WSDL documents to the UDDI registry of any service broker. Whenever a service requester asks for a service for tracing the safety record of a given food, the request is submitted by a SOAP-based barcode or RFID tag message through Internet to a service broker. Then the service broker replies a corresponding WSDL document which can be forwarded to a dedicated service provider for offering more detailed food safety information. Furthermore, two major software efforts have been achieved. One is a specific software system named working log which has been implemented at the supplier side for showing how to play the role of service provider such as collecting safety data, submitting WSDL documents, etc. The other is a user friendly portal with barcode and RFID interface which has been designed for showing how to interact between a service requester and a services broker.
