【摘要】：随着地理信息系统理论的发展和应用领域的扩大，基于地理信息系统的输油管网管理方式研究逐渐成为输油管网可视化管理领域的研究热点。现有的地理信息系统输油管网管理方式多为专属管理系统，未依托于管理模型，缺乏通用性。此外，管网数据模型粒度大，设备约束关系不完整且无法满足B/S下可视化空间分析等管理需求。因此以构建一个粒度划分合理、约束规则及功能完备的网络地理信息系统输油管网管理模型为目标，对管理模型的设计思路和实现方法进行了探索和研究。 首先，简化和抽象了输油管网业务模型，提取了核心工艺设备及辅助设备，给出了输油管网的多元组形式化定义。依照该定义构建了基于统一建模语言的输油管网逻辑数据模型，细化了数据划分粒度，经过模型转换，得到了基于Geodatabase的输油管网物理数据模型。在管网数据模型的基础上，设计了管理模型的层次架构，给出了数据层、服务层及交互层的内部模块组成、功能原理及交互方式并最终得到了管理模型的详细架构。 其次，给出了管理模型到原型系统映射的技术框架，分析了模型各层映射时的技术原理及路线。数据层中给出了基于关系数据库、Geodatabse和空间数据库引擎的输油管网空间数据和属性数据的组织结构及管理策略；服务层中完备了属性、行为和关系约束规则库，给出了基于ArcGIS的输油管网矢量图和空间服务的构建及调用方法；交互层中给出了交互层功能模块的组织方式及Web端调用各类数据管理及分析服务的方法。通过管理模型分层映射实现了从管理模型到原型系统的整体映射。 最后，以秦皇岛油港一公司输油管网管理需求为背景，应用本文提出的管理模型，通过Flex Viewer、.NET和SQL Server等技术在ArcGIS平台上设计并实现了输油管网管理系统。根据管理模型层次架构和模块划分来组装管理系统的数据结构、管网地图、业务逻辑、功能单元和系统界面，实现从管理模型到管理系统的映射。根据实验结果，，说明了所提出的管理模型具有通用性、正确性和实践价值。
[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.
