摘　　要：船舶交通管理系统VTS监管港区的所有船舶的安全航行,港区中船舶通航密度大,情况复杂.在该区域中部分船舶的AIS设备没有正常使用,VTS无法接收相应的信息导致管理受到影响.通过AIS传递的北斗卫星的定位数据与雷达信息转换为一致,然后利用程序计算出这两系统之间的固定误差,按照该值判定船舶AIS设备工作情况.船舶一进入港区报告线,数据库系统就开始不停地记录位置信息,VTS的统计方法按照设定时间阈值监控船舶的AIS是否正常运行,同时监控范围内的所有船舶的航行动态.Vessel Traffic services(VTS)supervises the safe navigation of all vessels in the port area.The navigation density of vessels in the port area is large and the situation is complex.In this area,AIS equipment of some vessels is not in normal use,VTS cannot receive corresponding information,and management is affected.In this paper,the positioning data of Bei Dou Satellite transmitted by AIS is converted to be consistent with the radar information.Then,the fixed error between the two systems is calculated by the program,and the working condition of the ship’s AIS equipment is determined according to the value.As soon as the ship enters the port reporting line,the database system starts to record the position information continuously.The statistical method of VTS monitors whether the AIS of the ship operates normally according to the set time threshold,and also monitors the navigation dynamics of all vessels in the area.
