應用於智慧電網之ZigBee/TCPIP轉換器備援協定

為了解決能源耗竭的問題，各國政府陸續推動智慧電網（Smart Grid）的基礎建設以有效利用能源，而智慧型電表基礎建設（Advanced Metering Infrastructure, AMI）則是實現智慧電網的第一步。它讓電力公司從電表收集到用電量資訊，再對電表下控制命令來做出因應的動作，以有效管理用電量。智慧型電表基礎建設的網路多半用到ZigBee和TCP/IP這兩種通訊協定，並且需要一個協定轉換器連接不同網路。因此，這個協定轉換器在系統中通常容易成為一個單點故障（Single Point of Failure）的所在。在本篇論文中，我們提出協定轉換器的冗餘方法來解決這個單點故障問題，使智慧電網的通訊更可靠。

Smart Grid is an infrastructure promoted by governments in many countries for facilitating efficient management of engergy in order to tackle the global warming and energy shortage problem. Advanced Metering Infrastructure (AMI) is an important part of Smart Grid to provide two-way communications for meters. This will allow the information and commands to be sent and received between meters and facility companies for energy management. AMI networks usually adopt ZigBee and TCP/IP as the transport protocols and a ZigBee/TCPIP translator must be installed between the two protocols. Therefore, the translator usually becomes a single point of failure in a communication system. In this thesis we propose redundant translators as a solution to this problem to make communication in Smart Grid more reliable.
