一种基于公共无线移动IP网络的 新型船舶自动识别模型

 为解决内河及沿海非公约适用船舶的避碰和安全航行问题,弥补基于VHF通信方式的AIS系统的不足,提出了基于公共无线网络移动IP的船舶自动识别模型——MIP-AIS.在研究该模型基本工作原理和船舶自动识别搜索算法的基础上,解决船舶在公共无线网络通信系统条件下,发现"邻近"船舶,"识别"船舶之间的实时信息传输和网络通信压力最小化等问题;分析了搜索算法的执行效率和系统数据传输的带宽需求等性能指标.实验表明,MIP-AIS能够满足当前沿海和内河船舶的自动识别需求,功能和性能均能满足国际标准要求.

A New Automatic Identification System(AIS) Model-MIP-AIS

An automatic identification system based on the public wireless mobile IP network—MIP-AIS is put forward,to give a solution of the navigation and collisions of non-IMO Convention ships in the coastal and inland waterways,which will compensate the AIS based on VHF communications for the application limitations.Based on the research of the foundation principle and search algorithm in MIP-AIS,some key technologies are resolved about finding the "adjacent" ships by the public wireless communications,achieving the real time information transmission among the "adjacent" ships and minimizing the burdens on the wireless communications.The efficiency of the search algorithm and the bandwidth demand of data transmission are analyzed.The experiments show that the MIP-AIS is capable to realize the ship identification in coastal and inland waterways,the function and performance of MIP-AIS can satisfy the requirements of IMO international standards.
