摘　　要：针对现有VTS(Vessl Traffic System)模拟器缺少利用AIS(Automatic Idnentification System)数据进行历史交通流规律的相关统计功能的不足,采用Postgre SQL建立用于存储天津港AIS历史数据的数据库,以电子海图为显示平台,结合Tee Chart图表插件作为辅助显示工具,对AIS原始数据按照通常操作人员的需求进行处理,实时给出天津港港区的历史船舶交通概况。设计出良好的人机交互界面,实现船舶历史轨迹的简单重绘,按照船舶类型、吃水、长度以及任意门线(进出港航道的截面)得出统计结果,可再现天津港的历史交通流规律,且以图表的形式展现统计结果,为研究天津港的交通流模型及VTS操作人员进行决策提供数据支持。The existing VTS simulator is unable to provide historical traffic flow by processing AIS data. To overcome the shortcomings,a database is built by using Postgre SQL to store Tianjin Port AIS history data,and real time Tianjin Port historic vessel traffic is provided based on electronic chart display platform. Combining with Tee Chart plug-in as auxiliary display tool,AIS raw data is processed in accordance with generally demands of the operator. A good man-machine interface is designed to realize the simple redraw of the ship history trace according to the type,draft,scale and arbitrary gate line（ inbound and outbound channel cross-section）,with statistical results obtained. The historical traffic flow rule of Tianjin Port can be recalled,and the results are showed in the form of chart and statements,which can provide the data support for studying the traffic flow model of Tianjin Port for decision making by VTS operators.
