【摘要】：随着城市基础设施建设步伐的加快,地下管网的类型不断增加,使得城市地下管网变得越来越复杂,因此,对地下管网的有效管理就显得越来越重要。现阶段大多数的管网信息系统是二维图形化的,其在表达管网错综复杂的空间关系上存在着明显的不足；另一方面,随着三维建模软件的出现和日益成熟,人们已渐渐不满足于二维图形化的地下管网信息系统。建立管网可视化信息系统,从而科学、准确的描述地下管网的分布状况,为城市规划和建设提供直观的场景展现逐渐成为人们的共识。本文论述了当前地下管网信息系统的现状与存在的不足,讨论了地下管网可视化信息系统构建的基础理论与关键技术,在此基础上结合地下管网管理的实际需求,基于Skyline和3dsMax软件构建研究区三维场景,并在微软Visual C#开发环境下设计实现了三维地下管网可视化信息系统。系统实现了三维管网的数据录入、综合管网的可视化展示、场景的基础操作,并根据管网管理的日常需求实现了管网属性的查询与统计、管网标注与量算以及管网的各项分析功能。论文主要内容如下： 1)研究背景和研究目的。阐述了地下管网管理和三维地理信息系统在国内外的研究现状,确定了本论文的研究内容与技术路线。 2)论述了管网可视化信息系统构建中的理论基础并对其中的关键技术进行了分析。首先介绍了地下管网的基础知识,其次详细介绍了Skyline软件及其二次开发接口,并总结了基于Skyline的开发流程,最后深入分析了三维模型可视化的方法与关键技术以及数据接口ADO.NET。 3)对系统进行了详细的设计。先是从功能需求和逻辑结构两方面对系统的总体结构进行设计,选择Skyline二次开发接口和Visual C#开发环境构建系统,进而对系统功能模块进行了详细的设计。 4)管网可视化信息系统的实现。以研究区2011年地下管网数据和影像数据为基础,通过Skyline软件构建研究区的三维场景并完成各项功能开发,生成研究区三维地下管网综合场景,验证了系统的可行性和实用性。 5)对系统的设计与实现进行了总结,谈到了系统的不足并提出展望。
[Abstract]:With the acceleration of urban infrastructure construction, the type of underground pipe network is increasing, which makes the urban underground pipe network more and more complex. Therefore, the effective management of underground pipe network becomes more and more important. At the present stage, most pipe network information systems are two-dimensional graphic, and there are obvious shortcomings in expressing the complicated spatial relationship of pipe network. On the other hand, with the appearance and maturity of 3D modeling software, People are not satisfied with the two-dimensional graphic underground pipe network information system. In order to describe the distribution of underground pipe network scientifically and accurately, it has become a common understanding to establish a visual information system of pipe network and provide an intuitive scene for urban planning and construction. This paper discusses the present situation and shortcomings of underground pipe network information system, discusses the basic theory and key technology of constructing underground pipe network visualization information system, and combines with the actual demand of underground pipe network management. Based on Skyline and 3dsMax software, the 3D scene of the research area is constructed, and the 3D underground pipe network visualization information system is designed and implemented in Microsoft Visual C # development environment. The system realizes the data input of 3D pipe network, the visual display of comprehensive pipe network, the basic operation of scene, and realizes the query and statistics of pipe network attribute according to the daily demand of pipe network management. The marking and calculation of pipe network and the analysis function of pipe network. The main contents of this paper are as follows: 1) the research background and purpose. The research status of underground pipe network management and 3D geographic information system at home and abroad is described. The research content and technical route of this paper are determined. 2) the theoretical basis of the construction of the pipe network visualization information system is discussed and the key technologies are analyzed. Firstly, the basic knowledge of underground pipe network is introduced, then the Skyline software and its secondary development interface are introduced in detail, and the development process based on Skyline is summarized. Finally, the methods and key technologies of 3D model visualization and the data interface ADO. Net. 3) are analyzed in detail. Firstly, the overall structure of the system is designed from the aspects of function requirement and logic structure, and the Skyline secondary development interface and Visual C # development environment are selected to build the system. Then the system function module is designed in detail. 4) the realization of the pipe network visual information system. Based on the underground pipe network data and image data of the research area in 2011, the 3D scene of the research area was constructed by Skyline software and the functions were developed to generate the comprehensive scene of the three-dimensional underground pipe network in the research area. The feasibility and practicability of the system are verified. 5) the design and implementation of the system are summarized, the shortcomings of the system are discussed and the prospect is put forward.
