摘要:	物聯網閘道器扮演著大量智慧物件(Smart things)與雲端連網伺服器的關鍵中介角色，目前學術界和產業已投入大量的研發資源從事物聯網閘道器相關技術和產品的研發。在小型、低功耗的物聯網應用，傳統閘道器系統使用微控制器作為核心，來實現底層裝置網路的管理和上層雲端伺服器功能和遠端行動計算服務。然而，使用單一微控制器的解決方案在系統擴充性及計算和通訊效率上難以應付物聯網的大量資料收集、管理、和通訊網路以及多樣性服務需求。本研究提出一個創新的多微控制器系統架構，結合一個基於FPGA的硬體橋接器，以及可擴充的多重微控制器，構成一個主從架構的高性能多微控制器的物聯網閘道器。此一系統具有分散式處理、微控制器間的高速通訊、豐富週邊的優點。在論文最後，我們以一個物聯網應用系統開發案例，來驗證我們所提出的多微控制器物聯網閘道器，並與現有的架構進行比較，實驗結果顯示本系統具有明顯的性能優勢。;The Internet of Things (IoT) gateway serves as a key intermediary between a considerable amount of smart things and their corresponding cloud networking servers. Academics and industry members have invested substantial research and development resources into developing IoT gateway-related technology and products. In small and low-power IoT applications, conventional gateway systems mainly use microcontrollers to perform lower-layer device network management, upper-level cloud server functions, and remote mobile computation services. However, regarding system scalability and computation and communication efficiency, solutions that use a single microcontroller cannot cater to the demands of IoT regarding large data collection, management, communication networks, and various other services. Therefore, this study proposed an innovative multimicrocontroller system framework, combining a field-programmable gate array-based hardware bridge and scalable multiple microcontrollers to construct a master–slave architecture of a high-performance multimicrocontroller IoT gateway. The proposed system features distributed processing, high-speed communication among microcontrollers, and compatibility with a wide variety of peripheral devices. In the end of this study, we implement an IoT application system case to verify our multimicrocontroller IoT gateway which has obviously more performance advantages than before.
