Abstract
En 中文
Due to the diversity of products and small batch sizes, production lines are often faced with reconfiguration or even line changes. Applying digital twin technology to production lines is one of the most promising approaches. However, factory personnel are not all aware and familiar with digital twin technology, and they have difficulty adapting or implementing digital twin scenarios. To more easily construct or reconfigure production line digital twin scenarios, this paper proposes a graphics-based, modular, and user-oriented digital twin software framework for production lines. The framework divides the digital twin implementation process into five functional modules: twin model construction, model operation, connection and interaction, control logic, visualization assistance and interaction, which are graphically encapsulated. The modular format helps standardize the construction and operation of the digital twin production line, and improves the flexibility and versatility of the framework. Meanwhile, multiple functional libraries are encapsulated to simplify the construction steps and processes based on graphical user interface. Combining visual programming to implement control logic in a low-code visual programming manner, reducing the difficulty of getting started. And various UI elements are used to enhance human-computer interaction. A digital twin platform was developed based on the proposed framework, and experiments were conducted with a hardware production line as an example. The experimental results show that it is feasible to construct digital twin production lines conveniently and reduce the complexity of the constructing process based on this platform, thus the feasibility of the framework is verified.
