| dc.description.abstract | 在工業物聯網的潮流下，工廠的控制裝置與設備聯網成為迫切需求，然而目前現場總線閘道器在系統擴充性及通訊頻寬上，難以滿足大量裝置在工業環境傳輸的即時性、大量資料收集、管理等需求。因此本研究提出多通道現場總線網路閘道器的硬體架構，以微控制器為核心，結合FPGA的八通道高速串列Modbus控制器以及上層可平行管理八通道的感測網路控制器，構成一個支援八通道主控端的現場總線網路閘道器。此系統可支援Modbus大量周邊裝置擴充，以及即時資料收集的功能。論文最後，我們以相同實驗環境下，模擬傳統Modbus現場總線並與本系統進行比較，實驗結果顯示本系統具有明顯的性能優勢，並以即時資料收集應用，驗證本系統有較佳的即時資料收集能力。 | zh_TW |
| dc.description.abstract | In Industrial Internet of Things, networking has become increasingly necessary for device controllers and factory equipment. However, current fieldbus gateways generally cannot meet the requirements for real-time transmission between numerous devices and substantial data collection and management in an industrial environment because of system peripheral expansion and insufficient communication bandwidth. Therefore, in this paper, we propose a hardware accelerator architecture for multichannel fieldbus gateways. The proposed system was combined with a microcontroller and hardware accelerator. The system core relies on a microcontroller to perform fieldbus gateway management. Additionally, we used a field-programmable gate array to implement a hardware accelerator, combining an eight-channel high-speed serial Modbus controller; the sensor network controller facilitates parallel management of the eight-channel Modbus controller. This system can support increases in the number of Modbus slave devices connected to the gateway, and it also provides functionality for real-time data collection. We simulated the conventional Modbus fieldbus and compared it with the proposed system in the same experimental environment. The results showed that the proposed system had a faster response time. We used a real-time data collection application to verify the proposed system’s performance and found that its capabilities were superior to those of the conventional system. | en_US |
