[Abstract]:At present, two-dimensional software tools such as AutoCAD are widely used for process layout planning in manufacturing enterprises. It is difficult to find the layout defects such as spatial interference and channel congestion. With the development and application of virtual reality and 3D digital technology, it is possible to carry out interactive process layout in virtual 3D environment. In this paper, the key technologies of the interactive 3D process layout system are studied, and the feasibility of the system is verified by a case study. Firstly, the modeling and description method of manufacturing resource information is studied in this paper, and the resource information model for process layout planning is established. This paper classifies the manufacturing resource objects, analyzes the information elements and the database storage structure of the workpiece, process and equipment resources, and defines the intermediate data description format of the information model by using XML technology. The data interface of the information index between the system and the database is realized. Secondly, the interactive three-dimensional process layout technology based on OSG virtual reality platform is studied. The key technologies of interactive layout in 3D virtual environment are studied from four aspects: pick-up technology of 3D model, manipulation technology, interactive roaming technology of scene and roaming technology of path. The interactive operation function of the system is realized. Based on the research of the bounding box collision detection technology, the interference test between the equipment resource models in the real-time dynamic layout of the system is realized, and the safety distance between the devices is considered to ensure the security of the layout. Thirdly, the 3D visualization technology of workshop logistics information is studied. Firstly, the visual information model of process route is constructed; the virtual path node is set up, and the shortest path of material transportation is calculated by using Dijkstra algorithm; the visualization standard of material flow is set up, and the information model of material flow is constructed. And in three-dimensional virtual environment for interactive visualization. Finally, based on the research of the above key technologies, the overall framework of the interactive 3D process layout system is designed, the key functional elements of the system are analyzed, and the application and feasibility of the system are verified with practical cases.
