Design of an Interactive Visualization System for the Process Workflow of an Intelligent Sub-Assembly Workshop

With the rapid development of intelligent manufacturing in the inland shipbuilding industry, traditional sub-assembly workflows urgently require transformation toward visualization, interactivity, and intelligence. This paper develops an interactive process workflow visualization system based on Unity. The system reconstructs the workshop environment and major equipment through 3D modeling, covering key operations such as steel plate cutting, laser cutting, intelligent sorting, AGV transportation, and welding. Users can select individual operations or the complete workflow via interface controls, enabling autonomous process control and dynamic demonstration. Furthermore, the system integrates a real-time equipment monitoring module, which leverages IoT technology to acquire operational parameters, working states, and performance indicators of critical equipment including laser cutters, welding robots, and AGVs, and presents them in a 3D visualized form. Compared with traditional flowcharts or video demonstrations, the proposed system provides greater intuitiveness and interactivity, supporting applications such as process training, production planning, bottleneck analysis, and equipment monitoring. This approach demonstrates significant application value and potential in process visualization, workforce training, equipment monitoring, and digital twin construction.
