摘要
为获取指定时间内到达指定区域或港口的船舶联系信息,开发基于自动识别系统(Auto-matic Identification System,AIS)数据的预抵船舶联系信息查询系统.该系统运用直接匹配、别名匹配和模板匹配等,结合预先建立的地理层次树,筛选出指定时间段内到达指定区域或港口的船舶;根据AIS数据与船舶资料数据库的关联,建立预抵船舶联系信息查询系统.实验表明,该系统可为船舶服务公司提供方便的查询途径,提高工作效率.
In order to obtain the contact information of the ships which are estimated to arrive at the des-ignated area or port during the designated period,an inquiry system for the contact information of the estimated arrival ship based on Automatic Identification System（AIS） data is developed.By using direct matching,alias matching and template matching,combining with the pre-built geographical hierarchy tree,the ships which are estimated to arrive at the designated area or port during the designated period are screened out.According to the relevance of the AIS data and the ship information database,the inquiry system for the contact information of the estimated arrival ship is developed.The experiment shows that the system provides a convenient way for shipping services,and improves the efficiency.
