【摘要】：随着全球社会经济的快速发展,船舶运输需求的不断增大,船舶安全也成为了密切关注的焦点。在海上,基于标准的电子海图显示与信息系统(ECDIS, Electronic Chart Display and Information System)和S57标准电子海图(ENC, Electronic Navigation Chart)重要技术手段的辅助,船舶航行安全得到有效保障；在内河,多数流域由于缺少电子航道图,船舶依然长期依靠着船员经验和雷达信号定位,无法满足现代航运的需求。为了保障内河船舶的航行安全,提高船舶救助能力,本文基于经济和技术上的考虑,提出了一种MapInfo电子矢量数据变换为S57标准数据以制作S57标准内河电子航道图的方法,继而将该电子航道图加载到ECDIS或电子海图系统(ECS, Electric Chart System)上,以提高内河船舶导航能力。除此之外,一方面,拓展了ECDIS/ECS的应用空间；另一方面,节省了制作内河电子航道图数据采集时间和构建内河电子航道图信息显示系统的经济开销。在充分研究MapInfo电子矢量数据和S57标准数据结构和内容的基础上,本文从数据的空间几何特性、特征描述信息和文件内容结构三个方面对比分析了MapInfo矢量数据与S57标准数据间的差异性和关联性,并分别设计了两种数据间的几何结构变换算法,特征信息匹配模型和文件结构内容映射模型；在理论分析的基础上,针对于数据变换系统功能上的需求,本文总体上设计了六个功能模块：主控模块、人机交互模块、参数配置模块、数据处理模块、数据映射模块和文件设计模块,基于Linux操作系统上QT软件开发平台,应用C++面向对象的编程思想,详细设计相应的类和对象以实现了各个模块的具体功能,完成了MapInfo矢量数据变换为S57标准数据的系统开发过程；然后,以吉林省松花湖水域的数据变换为例,展示了该数据变换系统的操作流程和数据变换后的电子航道图的应用效果,并对比分析了本课题研究的价值和实用效果；最后,对本文进行了总结。本论文的研究内容是导航研究所承担的国家支撑计划课题‘'AIS/GNSS船载导航设备关键技术与系统研制”(2012BAH36B02)研究内容的一部分。
[Abstract]:With the rapid development of global economy and the increasing demand of ship transportation, ship safety has become the focus of close attention. At sea, the safety of ship navigation is effectively guaranteed by the important technical means of ECDIS (Electronic Chart display and Information system) and S57 (Electronic Navigation Chart). Due to the lack of electronic waterway maps in most watersheds, ships still depend on crew experience and radar signal positioning for a long time, so they can not meet the needs of modern shipping. In order to ensure the navigation safety of inland water vessels and improve the ship salvage ability, a method of converting MapInfo electronic vector data to S57 standard data to make S57 standard inland river electronic channel map is proposed in this paper, based on economic and technical considerations. Then, the electronic channel chart is loaded into ECDIS or ECS (Electric Chart system) to improve the navigation ability of inland ships. In addition, on the one hand, it expands the application space of ECDIS / ECS, on the other hand, it saves the time of data acquisition and the economic expense of constructing the information display system of inland river electronic waterway map. Based on the full study of MapInfo electronic vector data and S57 standard data structure and content, the spatial geometric characteristics of the data are discussed in this paper. The differences and correlations between MapInfo vector data and S57 standard data are compared and analyzed in three aspects of feature description information and file content structure, and the geometric structure transformation algorithms between two kinds of data are designed respectively. Feature information matching model and file structure content mapping model. Based on the theoretical analysis, this paper designs six functional modules: main control module, human-computer interaction module, and according to the functional requirements of the data transformation system, the paper designs six functional modules: the main control module, the human-computer interaction module, the main control module and the human-computer interaction module. Parameter configuration module, data processing module, data mapping module and file design module, QT software development platform based on Linux operating system, using C object oriented programming thought, The corresponding classes and objects are designed in detail to realize the specific functions of each module, and the system development process of converting MapInfo vector data into S57 standard data is completed, and then, taking the data transformation of Songhua Lake in Jilin Province as an example, The operation flow of the data transformation system and the application effect of the electronic waterway map after the data transformation are shown, and the value and practical effect of the research are compared and analyzed. Finally, the paper is summarized. The research content of this thesis is a part of the research on the key technology and system development of AIS / GNSS shipborne navigation equipment (2012BAH36B02).
