臺灣博碩士論文加值系統

有鑑於目前工業上傳輸及訊息協定混亂，為了有效整合各家廠商，微軟等大企業提出OPC UA協定來試圖標準化整個產業，且由於資料來源過多缺乏整理與整合，學界與業界均有聚合伺服器的雛形出現，本論文提出解決當使用者過多時，傳統被動式更新節點方式所導致的網路負荷量過大之方法，讓被動式更新結合新一代OPC UA所提出的標準OPC UA Pub/Sub來主動式更新節點，再結合訊號伺服器的網路頻寬監控，一方面可以解決使用者過於頻繁存取聚合伺服器使得伺服器一直向來源OPC UA 伺服器存取所造成的重複或流量過大的問題，另外也可透過參數調試，避免Pub/Sub主動式更新若來源OPC UA 伺服器節點更新太過頻繁導致的網路阻塞。

In view of the messy in the communication protocols in the industry, many companies such as Microsoft have proposed the OPC UA protocol to try to standardize the entire industry to effectively integrate various vendors. Due to the excessive sources of data and the lack of collation and integration, the academic community and the industry have the prototype of aggregating servers. To solve the problem of excessive network load caused by traditional passive updating node, the method is proposed to combine passive updating and OPC UA Pub/Sub which is the newest standard proposed by OPC foundation for actively updating the node. With the help of network bandwidth monitoring which is part of signaling server, this method can not only solve the problem of excessive repetition or excessive traffic caused by the user accessing the aggregation server too frequently but avoid network congestion caused by too frequent source OPC UA server node updates when use Pub/Sub to update node.
