This course aims to equip students with the core concepts and applications of Human-Machine Interface (HMI), covering fundamental principles, graphical monitoring design, system development, practical applications, and future trends. First, the course introduces the definition, historical development, and industrial automation applications of HMI, helping students understand its key role in production monitoring and equipment management. Next, it delves into graphical monitoring design, including human-machine interaction principles, visual design, information display, and operational logic, ensuring that interfaces are both efficient and user-friendly. Additionally, the course covers HMI system development, including hardware and software architecture, communication protocols (such as Modbus and OPC), and data processing capabilities, enabling students to build a comprehensive technical understanding. To strengthen practical applications, students will study SCADA systems, touchscreen panels, and industrial monitoring case studies, gaining insights into the connection between theory and practice while fostering hands-on learning. Finally, the course explores the applications of IoT, AI, and big data in HMI, analyzing future trends in smart manufacturing. This course not only enables students to master theoretical and technical knowledge but also enhances their industry readiness and competitiveness in the job market.
