【摘要】：目前制造企业普遍采用二维软件工具如AutoCAD进行工艺布局规划，，难以发现空间干涉、通道拥挤等布局缺陷。随着虚拟现实技术与三维数字化技术的发展与应用，为在虚拟三维环境下进行交互式工艺布局提供了可能。本文结合企业应用需求，重点研究了交互式三维工艺布局系统的相关关键技术，并通过案例对系统的可行性进行了验证。 本文首先对制造资源信息建模与描述方法进行了研究，建立面向工艺布局规划的资源信息模型。对制造资源对象进行了分类，分析工件、工艺和设备资源的信息元素与数据库存储结构；利用XML技术定义了信息模型的中间数据描述格式，实现了系统与数据库之间信息索引的数据接口。 其次对基于OSG虚拟现实平台的交互式三维工艺布局技术进行了研究。分别从三维模型的拾取技术、操纵技术、场景交互式漫游技术和路径漫游技术四个方面对三维虚拟环境下的交互式布局关键技术进行了研究，实现了系统的交互操作功能；通过对基于包围盒碰撞检测的安全距离检测技术的研究，实现了系统实时动态布局过程中设备资源模型之间的干涉检验，考虑了设备之间的安全距离，保证了布局的安全性。 再次对车间物流信息的三维可视化技术进行了研究。首先构建工艺路线可视化信息模型；设置虚拟路径节点，并利用Dijkstra算法计算物料运输的最短路径；设定物流量的可视化标准，构建物流量的信息模型，并在三维虚拟环境下进行交互式可视化。 最后在上述关键技术的研究基础上，对交互式三维工艺布局系统的总体框架进行了设计，分析了系统的关键功能要素；结合实际案例，对系统进行了应用和可行性验证。
[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.
