Ship AIS Big Data Management, Analysis and Application Architecture Design

In order to fully explore the value of ship Automatic Identification System (AIS) big data in terms of statistical analysis and maritime supervision, the ship AIS big data management, analysis and application architecture was systematically proposed. Firstly, according to the characteristics of ship AIS big data, the processing flow and storage strategy of ship AIS big data were designed in order to support the following high efficient computation. Secondly, four basic algorithms based on ship AIS big data were proposed and realized, including ship trajectory reconstruction, section ship flow statistics, identification of ship entering and leaving the port, and ship navigation status judgement. Finally, on the basis of the four basic algorithms, ship AIS big data was applied to several scenes, including the section ship flow statistics, behavior supervision of ship normally using ship AIS equipment, behavior supervision of ship reporting its entering and leaving the port and so on. The application results show that ship AIS big data is valuable in terms of statistical analysis and maritime supervision to some extent.
