如何開創出基於物聯網的架構，滿足資料傳輸的需求，確保資料的連續性、一致性，是物聯網時代即時大數據收集的重要課題。本研究設計了一個具精密時間同步的藍牙即時資料收集網路，系統由三個功能模組所組成，包括檔案系統模組、時間同步模組、和資料同步模組，該系統採主從架構，在面對藍牙網路的低可靠度資料通訊問題，確保從屬端與主控端斷線期間還能獨立運作且資料具備連續性和一致性。我們將原本基於以太網的IEEE-1588精密時間同步協定導入藍牙物聯網中，以降低時間誤差並有效提高資料的正確性。通過一系列實驗，驗證藍牙即時資料收集、傳輸和儲存的連續性和一致性需求。;How to create a web-based architecture, meet the need for adequate data transmission and achieve the continuity and consistency of information, is an important topic of instant data collection in the Internet Era. The research designed a Bluetooth instant data collection network with precise time synchronization, the system consists of three functional modules, including the file system module, time synchronization module and data synchronization module. The system takes the master-slave architecture. In this way, the system can operate independently and achieve data continuity and consistency when the subordinate end and the main control end are disconnected, thus avoiding Bluetooth network low reliability data communication problems. We will introduce the Ethernet based IEEE-1588 Precision Time Synchronization Protocol into Bluetooth Internet of Things to reduce time error and effectively improve data correctness. Through a series of experiments, we verify the continuity and consistency requirements of Bluetooth real-time data collection, transmission and storage.
