【摘要】：隨著“工業(yè)化4.0”概念的提出,逆向工程在智能制造領域的應用越來越廣,逆向設計在數字化平臺設計開發(fā)領域發(fā)揮著舉足輕重的作用。現(xiàn)在人們對數字化平臺的功能要求越來越多,比如:可視化程度高、現(xiàn)場還原能力強、內容豐富、操作方便等。特別是一些大型工業(yè)基地的工作人員,一個完善的數字化平臺給他們帶來很多工作上的便利,這就要求數字化平臺的設計師不斷的學習,在設計方法上不斷的創(chuàng)新。針對以上問題,三維逆向設計在數字化系統(tǒng)設計的基礎設計方面提供了一種新方法。油庫熱力系統(tǒng)在油庫的儲備運營中起到至關重要的作用,油庫熱力系統(tǒng)三維數字化平臺在油庫的管理運營中更是突顯出很多便利。本文結合油田信息化創(chuàng)新試點工程項目,首先利用三維激光掃描儀對油庫熱力系統(tǒng)進行現(xiàn)場的掃描,獲取現(xiàn)場實景三維點云數據。點云數據在三維激光掃描儀配套軟件SCENE中進行拼接、降噪處理。由于油庫熱力系統(tǒng)在現(xiàn)場的占地面積較大,包含的工藝設備較多,工藝流程也相對復雜,因此,在現(xiàn)場進行掃描作業(yè)時,要求合理的布局每一站的掃描位置,以保證點云數據的完整和精度,同時還要考慮掃描工作的效率。本部分重點介紹點云數據的采集過程和方法以及數據在SCENE中拼接、降噪處理過程和點云數據的精度控制。然后利用三維CAD建模軟件3Ds MAX 2015的逆向工程設計模塊對點云數據進行加載預處理,然后對處理好的數據中的工藝設備和外部景觀進行三維建模,并創(chuàng)建燈光和賦予貼圖材質進行烘焙處理,建立一個虛擬現(xiàn)實的三維數字化場景。將完整的三維模型導入到Virtools虛擬開發(fā)平臺中,對三維模型數據進行參數設置,利用Virtools內部集成的模塊化程序和一些腳本程序設計方式設計出角色巡檢模擬以及相應的操作說明的交互模式,結合現(xiàn)場匯總的油庫熱力系統(tǒng)設備屬性信息,建立設備屬性信息數據庫,對熱力系統(tǒng)中設備維修維護及設備參數,工藝流程實現(xiàn)快速查詢,同時以動畫演示的方式實現(xiàn)對工作人員的安全培訓。實現(xiàn)了對油庫熱力系統(tǒng)的數字化和虛擬化。通過交互界面的設計和加入的音效處理豐富了系統(tǒng)的功能,增強了系統(tǒng)的可操作性。最后本文按照功能實現(xiàn)目標對設計完成的數字化系統(tǒng)進行運行和分析,三維模型場景真實感強,交互界面直觀全面,各模塊功能實現(xiàn)完備,系統(tǒng)具有很強的實用性,也有很大的推廣價值,達到設計目的。課題關鍵技術包括逆向建模技術和腳本程序的設計。三維數字化油庫熱力系統(tǒng)的設計應用具有很好的代表性和推廣意義。
[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.
