  3. 標準發展組之介紹

  4. EPCglobal簡介 • 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 • 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 • EPCglobal負責管理和推廣EPC工作，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

  5. EPCglobal簡介(續) • 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 • EPCglobal建立的網路架構可稱為「物聯網」(The Internet of Things)或EPCglobal Network • 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

  24. Capture – The Reader Interface EPCglobal Core Services and other Shared Services Shared Service Interactions Exchange of data about EPCs Company A Company B Capture 1010101010101 Low-Level Reader Protocol (LLRP) Reader Protocol Exchange of Physical objects with EPCs

  25. The Reader Interface Reader module Host Specifications of the interactions = Reader Interface

  26. Reader Protocol

  27. Reader Protocol 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。 以標籤讀取事件為基礎來達到讀取器控制。 包括預先設定的觸發（trigger）參數、初步的過濾（filter）機制等。

  28. Low-Level Reader Protocol (LLRP)

  29. LLRP 原理 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。 以標籤讀取事件為基礎來達到讀取器控制。 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。 LLRP目前是針對EPCglobal C1G2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。

  30. Capture – The Reader Management Interface EPCglobal Core Services and other Shared Services Shared Service Interactions Exchange of data about EPCs Company A Company B Reader Management Capture 1010101010101 Exchange of Physical objects with EPCs

  31. Reader Management 針對RFID讀取器中，管理各個讀取器之設定、狀態監控、以及事件警示通知等功能標準，其功能為： 可以搜尋RFID讀取器例如身份、天線數量等設定資訊。 可以監控RFID讀取器的作業狀態，例如讀取的標籤數量、通訊頻道狀態、健康狀態監控、天線連線程度、傳遞能量等級等。 可控制RFID讀取器的設定，例如啟動/關閉特定天線或功能等。 可以使用RFID讀取器管理功能，包括搜尋、韌體/軟體設定與更新，並管理讀取器耗電量。

  32. The Discovery, Configuration, and Initialization (DCI)

  33. DCI功能 讓讀取器能搜尋到一或多部存取控制器。 讓存取控制器能搜尋到一或多部讀取器。 讓讀取器能搜尋到一或多位Client端。 讓讀取器及存取控制器之間交換及驗證身分識別資訊。 讓Client端及存取控制器之間能驗證其連線和運作。
