“…For the case study, a sorting station that has industrial sensors and actuators was used and the results showed that it is a generic and flexible architecture based on existing DT frameworks, and since they are open architectures for smart manufacturing, they are key to solving problems of interoperability. In [18], they developed a DT that has integrated visualization technologies and the simulation of process parameters. The implementation is carried out in a typical machining process, which has an S7-1200 PLC and bidirectional communication based on the TCP/IP protocol, with the simulation module based on finite element modeling (FEM), which was implemented in ANSYS, and the virtual model was developed in Unity.…”

The present research proposes the implementation of an architecture for industrial process monitoring and control for a manufacturing execution system (MES) using an immersive digital twin (DT). For the design of the proposal, cyber–physical systems (CPS), MES, robotics, the Internet of Things, augmented reality, virtual reality, and open platform communication-unified architecture (OPC UA) communication protocols were used to integrate these technologies and enhance the functionalities of the DT by providing greater performance. The proposed work is implemented in an Industry 4.0 laboratory that is composed of Festo Cyber–Physical Factory and CP-Lab stations. The implementation of the architecture is based on ISO 23247, where the following requirements were considered for the design of DTs: (1) observable attributes and 3D design and visualization of all physical production lines in all of their stages, (2) a communication entity through the OPC UA protocol for the collection of state changes of manufacturing elements, (3) a DT entity where digital models are modeled and updated based on the collected data, and (4) user entities through the use of AR and VR to make manufacturing more efficient. The experimental results showed that the architecture enables interoperability between different platforms and control subsystems. It allows for the detection and diagnosis of problems during the execution of the production line; in addition, the high-fidelity simulation and AR and VR environments provided by the DT with data obtained in real time can improve the accuracy and efficiency of manufacturing through a more detailed analysis of the process, providing advantages such as interactive creation for customized products and continuous innovation.

In a fully automated factory, the Visualized Production Line serves as a crucial tool for management personnel to understand production progress and monitor the manufacturing process. The synchronization between the visualized line and the actual production line significantly impacts the efficiency of production supervision. Taking Controlled Logistics Terminals as an example, this article proposes the AS-TA-KS Method, which encompasses three steps: Animation Simplification, Timing Alignment, and Keyframe Synchronization. This method aims to achieve precise synchronization between the Simulated Production Line and the Visualized Production Line, while ensuring that the process data of the simulated line is not directly accessed. The experiment demonstrates that the method can maintain the time difference between simulated and visualized production line below an average of 0.08 seconds, with a synchronization rate of 99.97%. Our method advances the state-of-the-art method by an average of 5.22%. This case provides support for the real-time and reliability of modern intelligent manufacturing.

In conventional engineering education, issues such as the discrepancy between virtual and real environments, rigid practical operations, lack of reflective support, and a disconnect between online and offline learning prevail. Digital twin technology, with its high fidelity and real-time interaction features, presents an innovative instructional aid for engineering education. This study developed a digital twin learning system to assist instructors in implementing project-based teaching models in landscaping technology courses. To assess the effectiveness of this system, a quasi-experiment was designed. Seventy students from a vocational high school majoring in landscaping technology in China were recruited as participants. These students were divided into two groups, each consisting of 35 students, with the same teaching pace. The experimental group utilized the system to supplement the instructor’s teaching of landscaping courses, while the control group received instruction through traditional methods. The experiment lasted for eight weeks, comprising a total of 16 classes. Ultimately, the results indicated that students in the experimental group significantly outperformed those in the control group in critical thinking, cognitive load, learning experience, and academic performance. Additionally, this research examined the acceptance of learners toward using the digital twin learning system and its influencing factors based on the Technology Acceptance Model, aiming to provide insights into enhancing engineering education courses teaching effectiveness and targeted technological development.
