船舶静态信息数据

航海安全：船舶静态信息是船舶基本信息的集合，包括船舶长度、宽度、排水量等参数，能够帮助别的船只和海岸站了解该船的物理特征和位置参数，避免海难和碰撞。接收船舶实时AIS报文进行预处理，对预处理后的报文按照不同类型存储，将报文中的静态信息以mmsi为主键存储到数据库中，并对原有数据以mmsi为键值进行更新，再与ais动态信息相结合，形成完整的ais数据流。并对异常数据进行数据清洗。

Maritime Safety: Vessel static information is a collection of fundamental vessel parameters, including vessel length, width, displacement and other related metrics. It allows other vessels and coastal stations to acquire the physical characteristics and position data of the target vessel, so as to avoid maritime disasters and collisions. This dataset collects real-time AIS messages from vessels and conducts preprocessing on them. The preprocessed messages are stored according to their types, and the static information extracted from the messages is saved into the database with MMSI as the primary key. The original stored data is updated with MMSI as the key. Then, the static data is combined with AIS dynamic information to form a complete AIS data stream. Furthermore, data cleaning is carried out to handle abnormal data entries.
