摘要
实现船舶精确定位及航行状态远程实时监控,不仅对船舶的安全生产和任务执行情况做到实时跟踪、监管,还可通过航行轨迹回放协助事故追责及为船舶本身提供安全导航与避碰服务。通过采集大量山区航道中船舶接收北斗、GPS定位信息,分析数据特征,提取了速度、航向特征;综合两种定位方法的优点,提出了一套完整的信息融合方案,实现北斗、GPS定位信息的航迹融合纠偏。为内河山区航道船舶安全航行和监管通过了可靠的定位数据源。
To realize vessel＇s accurate positioning and its real-time sailing monitoring, we can not only monitor and control timely ships＇ safe operation, but also are able to help determining the accident responsibility by track playback and provide safe navigation and collision avoidance service for the vessel itself. The characteristics of the data for BDS and GPS location information in mountainous waterway are analyzed, and features such as the speed and direction of the vessel are extracted. A complete set of information fusion scheme algorithm is proposed to correct some error data of GPS or BDS. The experiments show that a reliable data source of navigation in the inland mountainous waterway can be ensured by the methods proposed for safety supervision.
