【摘要】：我国边防界河、界湖众多,界河航道的岸线、水深、航标、跨江建筑等情况复杂多变；碍航物、浅滩水域多,且位置尚不明了,不但给界河航行安全带来极大的隐患,而且也降低了界河通航效率。当前大部分界河没有水深等航道数据,仅较小一部分界河的某些河段有航道管理部门提供的航道图数据,在界河航行的边防巡逻艇没有相应的地理信息系统作为参考,没有精准的定位方法,对周边的地理信息、河床底质、水深变化等没有可依靠的数据支持。当河道发生改变时,仍然采用最为原始探深的办法进行航行,全凭经验进行航路探视。因此,从边防巡逻艇在中国界河内的航行需求,现场监管等的角度,迫切需要得到准确、丰富的电子航行图数据的支持。首先,本课题通过对中国界河的特点进行分析,结合边防巡逻艇在界河航行的信息需求得出了中国界河电子航行图的信息需求,提出了中国界河电子航行图系统的三大功能：水深的动态变化、等深线随水深变化的动态生成以及航道边界线随水位涨落的动态变化。其次,由于中国界河电子航行图系统是一个从航行信息的采集、信息的传输、制作与更新都独立完成的系统,这完全区别于电子海图的生产者与使用者不统一的模式。因此系统设计包括了从信息的采集、传输到航行图的制作与更新的整个流程,并且详细阐述了界河航行信息的采集方式、传输方式和电子航行图的制作方式。再次,系统设计完成后,对中国界河电子航行图的水深动态变化、等深线动态生成以及航道边界线随水位涨落的自动变化这三项关键技术进行了研究,并且对这几项关键技术进行了编程仿真验证,验证了研究成果的正确性。
[Abstract]:There are many border rivers and lakes in our country, and the waterfront, water depth, navigation marks and cross-river buildings of the border river channel are complex and changeable; the navigation obstructions, many shoals, and the location are still unclear, which not only bring great hidden dangers to the navigation safety of the border rivers,It also reduces the navigation efficiency of the boundary river.At present, most of the border rivers do not have waterway data such as water depth, and only a small part of some reaches of the boundary rivers have the channel map data provided by the waterway management department. The border patrol boats sailing in the border rivers do not have corresponding geographic information systems for reference.There is no accurate positioning method, and no reliable data support for the surrounding geographic information, river bed bottom, water depth change and so on.When the river course changes, it still uses the most original method of navigation, all based on experience to access the route.Therefore, from the point of view of navigation demand and on-site supervision of frontier patrol boats in China, it is urgent to obtain accurate and abundant electronic navigation chart data.First of all, by analyzing the characteristics of China's border rivers and combining the information needs of border patrol boats navigating along the border rivers, this paper obtains the information requirements of the electronic navigation map of China's border rivers.Three main functions of the electronic navigation map system for boundary rivers in China are presented: the dynamic variation of water depth, the dynamic generation of isobath with water depth and the dynamic change of waterway boundary line with the fluctuation of water level.Secondly, because the electronic navigation chart system of China boundary river is a system which is independent from the collection, transmission, production and update of navigation information, it is completely different from the unified mode of producer and user of electronic chart.Therefore, the system design includes the whole process from the collection of information, transmission to the making and updating of navigation map, and expounds in detail the collection mode, transmission mode and electronic navigation map making mode of navigation information of boundary river.These key technologies are verified by programming and simulation, and the correctness of the research results is verified.
