工業 4.0 推動智慧製造的演進變革，透過工業互聯網路串連製造系統中的感測器、生產機台與可程式化控制設備，讓大量的生產數據得以即時收集並且傳遞到生產監控系統進行後續的分析與處理。但是工廠內的生產機台與控制設備有著各自不相容的通訊協定，這些無法彼此溝通的通訊協定往往造成資料交換的傳輸瓶頸與衍生網路設備難以有效管理的問題。因此本研究提出以硬體加速的方式，設計 CANopen 通訊協定的硬體加速器，利用乙太網路為資料傳輸介面，透過 UDP 封包傳輸 CANopen 訊息，解決不同設備之間資料交換的問題，也讓網路設備得以有效地管理。本研究利用 Intel Altera FPGA作為實驗平台，以 MIAT 硬體設計方法論設計與實作 CANopen slave 通訊協定，搭配影像串流傳輸的應用來驗證網路資料封包的高速傳輸效能。;Industry 4.0 promotes the evolution of smart manufacturing. Sensors, production equipment and programmable logic controllers in manufacturing systems connect through industrial internet and allow a large amount of production data can be collected in real-time and passed to the production monitoring system for subsequent analysis and processing. However, the production equipment in the factory have their own incompatible communication protocols. Different communication protocols that cannot communicate with each other often cause the transmission bottleneck` of data exchange and the problem that derivative the network equipment are difficult to manage effectively. Therefore, this study proposes to design the hardware accelerator of the CANopen communication protocol using Ethernet as the data transmission interface. The CANopen messages are transmitted through UDP packets, which solve the problem of data exchange between different devices and also allow network devices to be effectively managed. This study uses Intel Altera FPGA as the experimental platform and use the MIAT hardware design methodology to design and implement the CANopen slave controller. With the application of video streaming to verify the high-speed transmission performance of network data packets.
