| dc.description.abstract | 現代製造場域大量引入電腦系統蒐集加工資料，提供給操作員與決策者足夠的數據協助製程改善。然而不同的廠商的機器使用不同的通訊方式與格式，使得管理與機器間資訊交互十分困難。MTConnect 與 OPC UA 提供了傳輸協定與共通格式的選項，並被廣泛應用於電腦數值控制工具機中。近年來工業4.0的概念被廣泛採用，資訊安全措施也越發重要。然而古早時代的機器無法直接整合進現代系統，或符合現代資訊安全標準。本研究目標在利用MQTT之Application layer整合製造場域之古早機器、溝通受限機器之資訊傳遞與提升傳遞品質、降低邊緣設備負擔、使用者授權與憑證使用。並進一步探討未來OPC UA PubSub功能的可能性。 | zh_TW |
| dc.description.abstract | Computer systems are integral to modern manufacturing, providing operators and decision-makers with detailed insights into production processes. However, communication methods and format between machines and computers vary widely among manufacturers, posing challenges for managing and interoperability. Standards like MTConnect and OPC UA address transmission issues and data formatting, and widely adopted in CNCs. With rising cybersecurity concerns as Industry 4.0 has been widely adopted, legacy machines struggle to meet modern specifications. This thesis proposes methods to integrate legacy and communication-restricted machines transferring data with MQTT's application layer, enhance transmission quality, reduce burden for edge device, and usage of authentication and certification. Further discuss the possibility of using OPC UA PubSub. | en |
