数据挖掘技术在海流要素辅助船舶导航中的应用研究

The Application Research of Data Mining Technology in the Assisting Ship Navigation Using Ocean Current

海流对船舶导航、航行安全影响较大。本文在对海流研究成果和海洋环境数据库进行深入研究的基础 上,详细考察了船舶在航行过程中对海流信息的应用环境及需求。为提高业务化应用能力,采用模式分析等 数据挖掘技术,提出了实测数据融合的技术方案,给出了海流要素辅助船舶导航的应用模式。最后,以电子海 图系统为平台,初步建立了海流要素辅助航迹模拟、船位校正等应用系统。

Ocean current exerts a great influence on ship navigation and sailing safety. Based on the further investigation in the research results of ocean current and ocean environmental database, the ship applied environment and demand for ocean current information in the navigating course are studied in this paper. For improving the application ability of operation, authors set up meta-knowledge applica- tion environment of ocean current information, put forward the technological scheme that merges the surveyed data adopting the data mining technology such as mode analysis etc and the assisting navigation application mode using ocean current. Finally, the application system is designed in which ocean current assists simulative navigation , checks and corrects location of ship, offers reference for the sailing on the platform of ECDIS.
