【摘要】：随着“工业化4.0”概念的提出,逆向工程在智能制造领域的应用越来越广,逆向设计在数字化平台设计开发领域发挥着举足轻重的作用。现在人们对数字化平台的功能要求越来越多,比如:可视化程度高、现场还原能力强、内容丰富、操作方便等。特别是一些大型工业基地的工作人员,一个完善的数字化平台给他们带来很多工作上的便利,这就要求数字化平台的设计师不断的学习,在设计方法上不断的创新。针对以上问题,三维逆向设计在数字化系统设计的基础设计方面提供了一种新方法。油库热力系统在油库的储备运营中起到至关重要的作用,油库热力系统三维数字化平台在油库的管理运营中更是突显出很多便利。本文结合油田信息化创新试点工程项目,首先利用三维激光扫描仪对油库热力系统进行现场的扫描,获取现场实景三维点云数据。点云数据在三维激光扫描仪配套软件SCENE中进行拼接、降噪处理。由于油库热力系统在现场的占地面积较大,包含的工艺设备较多,工艺流程也相对复杂,因此,在现场进行扫描作业时,要求合理的布局每一站的扫描位置,以保证点云数据的完整和精度,同时还要考虑扫描工作的效率。本部分重点介绍点云数据的采集过程和方法以及数据在SCENE中拼接、降噪处理过程和点云数据的精度控制。然后利用三维CAD建模软件3Ds MAX 2015的逆向工程设计模块对点云数据进行加载预处理,然后对处理好的数据中的工艺设备和外部景观进行三维建模,并创建灯光和赋予贴图材质进行烘焙处理,建立一个虚拟现实的三维数字化场景。将完整的三维模型导入到Virtools虚拟开发平台中,对三维模型数据进行参数设置,利用Virtools内部集成的模块化程序和一些脚本程序设计方式设计出角色巡检模拟以及相应的操作说明的交互模式,结合现场汇总的油库热力系统设备属性信息,建立设备属性信息数据库,对热力系统中设备维修维护及设备参数,工艺流程实现快速查询,同时以动画演示的方式实现对工作人员的安全培训。实现了对油库热力系统的数字化和虚拟化。通过交互界面的设计和加入的音效处理丰富了系统的功能,增强了系统的可操作性。最后本文按照功能实现目标对设计完成的数字化系统进行运行和分析,三维模型场景真实感强,交互界面直观全面,各模块功能实现完备,系统具有很强的实用性,也有很大的推广价值,达到设计目的。课题关键技术包括逆向建模技术和脚本程序的设计。三维数字化油库热力系统的设计应用具有很好的代表性和推广意义。
[Abstract]:With the development of the concept of "industrialization 4.0", reverse engineering is more and more widely used in the field of intelligent manufacturing, and reverse design plays an important role in the design and development of digital platform. Nowadays, there are more and more demands on the function of digital platform, such as high degree of visualization, strong ability of field restoration, rich content, convenient operation and so on. In particular, some large industrial base staff, a perfect digital platform to bring them a lot of work convenience, which requires the designers of the digital platform to constantly learn, in the design method of continuous innovation. In view of the above problems, 3D reverse design provides a new method for the basic design of digital system design. The thermal system of oil depot plays an important role in the storage operation of oil depot, and the three-dimensional digital platform of thermal system of oil depot is more convenient in the management and operation of oil depot. In this paper, the 3D laser scanner is used to scan the thermal system of the oil depot in order to obtain the 3D point cloud data of the actual scene. The point cloud data is stitched and processed in the three-dimensional laser scanner software SCENE. Because the thermal system of the oil depot occupies a large area in the field, contains more process equipments, and the technological process is relatively complex, therefore, the scanning position of each station is required to be reasonably arranged when the site is being scanned. In order to ensure the integrity and accuracy of point cloud data, the efficiency of scanning should be considered at the same time. This part mainly introduces the acquisition process and method of point cloud data, the data splicing in SCENE, the process of noise reduction and the precision control of point cloud data. Then the reverse engineering design module of 3D CAD modeling software 3Ds MAX 2015 is used to load and preprocess the point cloud data, and then the process equipment and external landscape in the processed data are modeled. And create lighting and texture for baking, and create a virtual reality 3D digital scene. The complete 3D model is imported into the Virtools virtual development platform to set the parameters of the 3D model data. The interactive mode of role patrol simulation and corresponding operation instructions is designed by using the modular program integrated within Virtools and some script programming methods, and the equipment attribute information of oil depot thermal system is combined with the field summary. The database of equipment attribute information is set up, the maintenance and maintenance of equipment and the equipment parameters in the thermal system are carried out, the process flow is quickly queried, and the safety training of the staff is realized by animation demonstration. The digitization and virtualization of the thermal system of oil depot are realized. The design of the interface and the sound effect processing enrich the function of the system and enhance the maneuverability of the system. Finally, according to the function realization goal, this paper runs and analyzes the digital system completed by the design. The 3D model scene is realistic, the interactive interface is intuitive and comprehensive, the function of each module is complete, and the system has strong practicability. Also has the very big promotion value, achieves the design goal. The key technologies include reverse modeling and script design. The design and application of three-dimensional digital oil depot thermal system has good representativeness and popularization significance.
