【摘要】：隨著地理信息系統(tǒng)理論的發(fā)展和應(yīng)用領(lǐng)域的擴(kuò)大，基于地理信息系統(tǒng)的輸油管網(wǎng)管理方式研究逐漸成為輸油管網(wǎng)可視化管理領(lǐng)域的研究熱點。現(xiàn)有的地理信息系統(tǒng)輸油管網(wǎng)管理方式多為專屬管理系統(tǒng)，未依托于管理模型，缺乏通用性。此外，管網(wǎng)數(shù)據(jù)模型粒度大，設(shè)備約束關(guān)系不完整且無法滿足B/S下可視化空間分析等管理需求。因此以構(gòu)建一個粒度劃分合理、約束規(guī)則及功能完備的網(wǎng)絡(luò)地理信息系統(tǒng)輸油管網(wǎng)管理模型為目標(biāo)，對管理模型的設(shè)計思路和實現(xiàn)方法進(jìn)行了探索和研究。 首先，簡化和抽象了輸油管網(wǎng)業(yè)務(wù)模型，提取了核心工藝設(shè)備及輔助設(shè)備，給出了輸油管網(wǎng)的多元組形式化定義。依照該定義構(gòu)建了基于統(tǒng)一建模語言的輸油管網(wǎng)邏輯數(shù)據(jù)模型，細(xì)化了數(shù)據(jù)劃分粒度，經(jīng)過模型轉(zhuǎn)換，得到了基于Geodatabase的輸油管網(wǎng)物理數(shù)據(jù)模型。在管網(wǎng)數(shù)據(jù)模型的基礎(chǔ)上，設(shè)計了管理模型的層次架構(gòu)，給出了數(shù)據(jù)層、服務(wù)層及交互層的內(nèi)部模塊組成、功能原理及交互方式并最終得到了管理模型的詳細(xì)架構(gòu)。 其次，給出了管理模型到原型系統(tǒng)映射的技術(shù)框架，分析了模型各層映射時的技術(shù)原理及路線。數(shù)據(jù)層中給出了基于關(guān)系數(shù)據(jù)庫、Geodatabse和空間數(shù)據(jù)庫引擎的輸油管網(wǎng)空間數(shù)據(jù)和屬性數(shù)據(jù)的組織結(jié)構(gòu)及管理策略；服務(wù)層中完備了屬性、行為和關(guān)系約束規(guī)則庫，給出了基于ArcGIS的輸油管網(wǎng)矢量圖和空間服務(wù)的構(gòu)建及調(diào)用方法；交互層中給出了交互層功能模塊的組織方式及Web端調(diào)用各類數(shù)據(jù)管理及分析服務(wù)的方法。通過管理模型分層映射實現(xiàn)了從管理模型到原型系統(tǒng)的整體映射。 最后，以秦皇島油港一公司輸油管網(wǎng)管理需求為背景，應(yīng)用本文提出的管理模型，通過Flex Viewer、.NET和SQL Server等技術(shù)在ArcGIS平臺上設(shè)計并實現(xiàn)了輸油管網(wǎng)管理系統(tǒng)。根據(jù)管理模型層次架構(gòu)和模塊劃分來組裝管理系統(tǒng)的數(shù)據(jù)結(jié)構(gòu)、管網(wǎng)地圖、業(yè)務(wù)邏輯、功能單元和系統(tǒng)界面，實現(xiàn)從管理模型到管理系統(tǒng)的映射。根據(jù)實驗結(jié)果，，說明了所提出的管理模型具有通用性、正確性和實踐價值。
[Abstract]:With the development of GIS theory and the expansion of application field, the research of pipeline network management mode based on GIS has gradually become the research hotspot in the field of pipeline network visual management. The existing GIS pipeline network management mode is mostly exclusive management system, not relying on the management model, lack of generality. In addition, the pipe network data model has large granularity, incomplete equipment constraints and can not meet the requirements of visual spatial analysis under B / S. Therefore, with the goal of constructing a network pipeline network management model with reasonable granularity partition, constraint rules and complete functions, the design idea and implementation method of the management model are explored and studied. Firstly, the operation model of pipeline network is simplified and abstracted, the core process equipment and auxiliary equipment are extracted, and the formal definition of multivariate group of pipeline network is given. According to this definition, the logical data model of pipeline network based on unified modeling language is constructed, and the granularity of data partition is refined. After model transformation, the physical data model of pipeline network based on Geodatabase is obtained. Based on the data model of pipe network, the hierarchical structure of the management model is designed, and the internal modules of the data layer, the service layer and the interaction layer are given, and the function principle and interaction mode are obtained. Finally, the detailed framework of the management model is obtained. Secondly, the technical framework of the mapping from the management model to the prototype system is given, and the technical principle and route of the mapping of each layer of the model are analyzed. In the data layer, the organization structure and management strategy of pipeline network spatial data and attribute data based on relational database Geodatabse and spatial database engine are given. The construction and transfer method of vector diagram and space service of pipeline network based on ArcGIS are given, and the organization mode of interactive layer function module and the method of calling all kinds of data management and analysis services by Web terminal are given in the interaction layer. The whole mapping from management model to prototype system is realized by hierarchical mapping of management model. Finally, based on the requirement of pipeline network management in Qinhuangdao Oil Port Company, a pipeline network management system is designed and implemented on the platform of ArcGIS by using the management model proposed in this paper and using Flex Viewer,.NET and SQL Server technologies. The data structure, network map, business logic, function unit and system interface of the management system are assembled according to the hierarchical structure and module partition of the management model, and the mapping from the management model to the management system is realized. The experimental results show that the proposed management model is universal, correct and practical.
