摘　　要：针对目前岸台基站或卫星基站还不能对全球尤其是位于交通繁忙海域的船舶进行连续有效的监控的问题,设计一种海上船舶自动识别系统(automatic identification system,AIS)移动基站(简称船舶基站),仿真大量船舶基站对全球船舶的监控效果。从全球所有船舶中随机选取部分船舶作为船舶基站进行仿真得出:在每天更新一次船位的情况下,全球船舶基站的最佳设置数是3500,覆盖率约为84.31%;船舶基站的AIS信号监控范围基本覆盖全球所有有航线海域,且单片海域的覆盖率普遍在85%以上。In view of the problem that shore base stations or satellite base stations can not conduct continuous and effective monitoring on the global ships,especially ships in busy traffic sea areas,the offshore automatic identification system(AIS)mobile base stations(ship base stations,in short)are designed,and the monitoring effect of a large number of ship base stations on global ships is simulated.Some ships are randomly selected from all ships worldwide as ship base stations for simulation.It is concluded that,under the condition of ship position update once a day,the optimal setting number of the global ship base stations worldwide is 3500,and the coverage rate is about 84.31%;the AIS signal monitoring range of ship base stations basically covers all the route sea areas worldwide,and the coverage rate of single sea area is generally above 85%.
