The invention provides a rapid updating method for complete static information of a shipborne automatic identification system, and the method comprises the following steps: S1, constructing a database which comprises an MMSI number and ship information corresponding to the MMSI number; s2, acquiring an AIS signal of the ship in real time, and analyzing data in the AIS signal; s3, judging whether the MMSI number in the AIS signal data exists in a database or not, and if yes, updating ship data corresponding to the MMSI number in the AIS signal data to ship information corresponding to the MMSI number in the database; and if not, writing the MMSI number in the AIS signal data and the corresponding ship information into a database. Through the method, the static information of the ships in the database can be quickly updated and stored, so that the ship information is complete, AIS information matching and scheduling can be accurately carried out when the ships communicate with each other or the ships communicate with the scheduling center, and thus the ship navigation safety is effectively ensured.
本发明提供的一种船载自动识别系统完整静态信息快速更新方法,包括以下步骤:S1.构建数据库,数据库包括MMSI号以及MMSI号对应的船舶信息;S2.实时获取船舶的AIS信号,并解析AIS信号中的数据;S3.判断AIS信号数据中的MMSI号是否存在于数据库中,如是,则将AIS信号数据中的MMSI号对应的船舶数据更新至数据库中该MMSI号对应的船舶信息中;如否,则将该AIS信号数据中的MMSI号以及对应的船舶信息写入至数据库中。通过上述方法,能够快速的对数据库中的船舶的静态信息进行更新、存储,使得船舶信息完整化,当船舶之间或者船舶与调度中心之间通信时能够准确进行AIS信息匹配以及调度,从而有效确保船舶航行安全。
