上一筆

隨著物聯網技術的發展，其應用層面也日益廣泛。現今物聯網技術已擴及各行各業，其中也包括了應用於工業製造領域的工業物聯網，其透過感測器、網際網路、巨量資料收集及分析等技術整合，進而有效提高現有產業的生產效率並創造新商機。

由於廠區中不同製造商生產的設備通常採用不同的通訊協議，要使它們進行通訊整合需要編寫大量的通訊程式，使得製造業要自行創建廠區的工業物聯網架構相當困難。本研究使用樹莓派作為物聯網架構中的閘道器，透過乙太網將廠區中所有設備連接起來，使用 Node-RED以各種通訊協定與不同加工機臺控制器及感測器建立資料交換並對資料進行處理製作成可視化圖表顯示在創建的人機介面網站上或存至SQLite資料庫中以備後續分析。

為了驗證此系統的可行性，本研究實際將前述的系統架構實施在台灣科技大學工業 4.0中心中，連接設備包含使用OPC UA通訊協定的西門子 Sinumerik 840D sl控制器、發那科 0i Tf控制器與使用Modbus通訊協定的AH500 PLC及各電能感測器。並運用從設備取得的資訊製作了有價值的可視化圖表，能夠進行分析並提供管理人員進行更準確的判斷以減少能源的損耗。

With the development of the Internet of Things (IoT) technology, the application of IoT is increasingly extensive.The IoT technology integrates techniques such as sensors, the Internet, and big data analytics, thereby effectively improving the productivity of industries. Nowadays, IoT technology has gradually penetrated various sectors in the industry.

Since the equipment produced by different manufacturers usually adopts different communication protocols, it is necessary to work with many protocols in a workshop for communication, making it difficult for the manufacturing industry to implement the IoT structure of the factory. The objective of this research was to use the low cost Raspberry Pi and open source Node Red to realize an IoT that small and medium sized enterprises can use. The IoT architecture can connect many devices, machine tool controllers, and sensors through various communication protocols and illustrate the data in charts of the human machine interface or stored in the SQLite database for subsequent analysis.

To verify the feasibility of this system, we implemented it in the Industry 4.0 Center of the National Taiwan University of Science and Technology. We used the OPC UA communication protocol in Node RED to connect Siemens Sinumerik 840D sl controller and Fanuc 0i Tf controller and used Modbus/TCP to communicate with Delta PLC AH500. Various charts were created to visualize data, which can then be analyzed to provide more information, such as the availability of the machines and the power usage of the building.
