GS 1組織簡介 p EAN是創立於 1977年的非營利中立性國際組織總部設在布魯塞爾。 p 目前據有108個國家或區域會員，另外有28個國家由總會直轄。 p 2002年 11月UCC加入EAN成為會員之一，促使標準發展全球一致化。 p

GS 1宗旨與策略基礎商業的全球共通語言整體的益處：改善整體供應與需求鏈的效率及資訊的透通度自動化識別全球標準商業訊息電子交換全球標準全球資料同步化的環境無線射頻識別技術為基礎的全球標準快速及準確的商品，資產或者地區的識別

EPCglobal簡介 p 1999年MIT成立了Auto-ID中心 (Auto-ID Center)，並且提出了「產品電子碼 (Electronic Product Code, EPC) 」的概念 p 2003年 10月31日，由EAN與UCC創建了另一個非營利性國際組織EPCglobal Inc. ，之後與七所知名大學共同經營Auto-ID Labs p EPCglobal負責管理和推廣EPC 作，並與Auto-ID Labs保持密切合作，使研究機構與使用者之間架起一座溝通的橋樑 © 2011 GS 1 TW

EPCglobal簡介(續) p EPCglobal成立的目的是為了推動EPC機制，並且訂定標準規範，使這個機制能在全球廣泛地應用 p EPCglobal建立的網路架構可稱為「物聯網」(The Internet of Things)或EPCglobal Network p EPCglobal Network利用現有網際網路架構，在全球建立起一個龐大的物品資訊交換網路，並且使所有參與流通的物品都具有唯一的產品電子碼，藉由EPCglobal網路架構相關元件，將使具備EPC號碼的物品，在網路上準確的定位與追蹤，並且為每項物品建立一套完整的電子履歷，使偽造商品不能流通 © 2011 GS 1 TW

The Reader Interface Host/ Client Reader module Specifications of the interactions = Reader Interface

Low Level Reader Protocol - LLRP p LLRP 提供Client端和Reader之間溝通的程序和格式。 p 其協議數據單元稱之為訊息。 n 由Client端傳送Reader端之訊息包括Reader的組態 (configuration)獲得和設定、搜尋Reader能力以及管理Reader盤查和存取操作。 n 由Reader端傳送Client端訊息包括回報Reader狀態、無線射頻調查(RF Servey)以及盤點和存取結果。 © 2011 GS 1 TW

LLRP功能 p 將命令從RFID讀取器傳送至物件標籤、讀取標籤資料、寫入資料至標籤、處理標籤使用者與標籤身份資料、並進行其他如刪除、鎖定等功能。 p 以標籤讀取事件為基礎來達到讀取器控制。 p LLRP應用RFID空中通信協定的指令和計時的參數，提供更底層讀取器運作的存取控制。 p LLRP目前是針對EPCglobal C 1 G 2的空中協定，但其規格架構可以允許未來其他的空中介面協定整合進來。 © 2011 GS 1 TW

What should the middleware do? Middleware should include 7 core capabilities: 1) Reader and device management Allows users to configure, deploy & issue commands to readers through common interface. 2) Data management Ensures captured data is intelligently filtered & routed to appropriate destinations 3) Application integration You need messaging, routing & connectivity features to reliably integrate RFID data into existing systems (e. g. ERP, WMS or CRM) 4) Partner integration You need B 2 B integration features (e. g. partner profile management & communication protocols) to efficiently integrate with partner’s data over EDI or web-based systems © 2011 GS 1 TW

What should the middleware do? 5) Process management Allows orchestrating RFID related end-to-end processes. E. g. link receiving process to inventory & POS process so system automatically reorders more products without human intervention when inventory is too low 6) Packaged RFID content You don’t have to start developing RFID applications (e. g. shipping or asset tracking) from scratch. 7) Architecture scalability Allows system to balance processing load across multiple servers & reroute data automatically if a server fails. © 2011 GS 1 TW

Core Business Vocabulary (CBV) p 本部標準定義符合EPCIS使用之特定字彙和其資料值，使得不同公司以及公司內部進行資料交換時能有得以依據的機制。 p CBV定義EPCIS之Event data內核心字彙，並適用於一般商業情境之資料分享。因此該標準提供統一的字彙及其代表的意義，讓供應鏈裡不同的節點對該物件資料能有相同的理解。

Core Business Vocabulary (CBV) p 在EPCglobal架構裡，CBV與 EPCIS為並行的標準。 n EPCIS定義架構裡的資料格式和事件資料。 n CBV屬於EPCglobal資料標準之一，定義存在於EPCIS資料格式內的特定資料值(data values)。

Core Business Vocabulary (CBV) p 每一個EPCIS事件資料內，說明物件為何(Why)被讀取時，用biz. Step field表示。biz. Step field內容在符合CBV 標準要求下，以URI格式呈現。e. g. 下圖biz.

Core Business Vocabulary (CBV) Business Steps Value Definition Examples Shipping 出貨 Indicates the overall process of picking, staging, loading and departing. It may be used when more granular process step information is unknown or inaccessible. It may indicate a final event from a shipping point. 代表揀貨、理貨、裝貨和啟運之整體程序。該字彙可使用於上述程序之資訊，代表出貨步驟的最終事件。 Manufacturer A loads and reads product into the shipping container and closes the door. The product has been read out of the shipping facility. 製造商裝貨入出貨貨櫃並讀取，關上貨櫃門。產品出貨時可由讀取設備讀取。 © 2011 GS 1 TW
