摘要
针对传统航标布设作业对人工经验的依赖,提出集成定位数据、测深数据和航道流向信息的航标布设定位方法。该方法利用测深数据计算漂流半径,将漂流半径与流向信息联合确定欲至位,以欲至位与目标位的空间关系实现抛标船引导。同时,分析传统浮标法获取流向图的不足,提出以ADCP断面流向采集并插值加密的方式获取流向图。在此基础上,设计了集成GPS、测深仪和流向图的航标布设辅助定位系统,实现了不增加硬件成本前提下的航标布设引导自动化,提高了作业效率。
According to artificial experience dependence in placing navigation mark,it presents the integrated positioning method of placing navigation mark based on GPS data and depth data and flow graph.Floating radius can be got through depth data,and the wanted position of navigation mark can be got through floating radius and flow graph.Acoustic doppler current profilers(ADCP)is adopted to measure direction of the section.The flow graph can be drawed by using interpolation.And the buoy method can be replaced by this method.Positioning system and depth sounder and flow graph are included in this system.Automation level and work efficiency can be improved by the premise of not increased cost.
