Technical Field
The invention relates to the field of ship alignment, in particular to a ship alignment method based on ship AIS and ship-stage data.
Background
In the modern time, a new competitive era with ocean development as a theme, and the rapid development of trade economy promotes a water transportation network. The construction of "ocean forcing" has become a national important strategy. With the overall development of the water transportation industry in the modernization, intelligentization and integration directions, the Automatic Identification System (AIS) is used as a novel digital navigation aid system and equipment, and the only aim of the Automatic Identification System (AIS) is to automatically exchange information about names, routes, speeds, real-time position information, types, goods and the like of ships which are allowed to approach each other. By exchanging this information, the captain of each ship can make better decisions based on the necessity of changing course or speed in time, depending on various contingencies. The AIS may also make it easier for each vessel to contact other vessels wirelessly.
As is well known, each ship has a specific ship name, and theoretically, the ship names and the ships are in one-to-one correspondence, but as the situation that multiple ship companies supply ships for storage in order to save the transportation capacity often occurs, however, each ship company cannot always keep the ship names of the same ship in a ship database because the ship information is not updated in time, the situation that the ship names of the ship company for lifting the head and the ship company for transporting on the bill are not consistent may be caused, and thus, no trouble is caused to customers. Therefore, how to align the ships of each ship company is an urgent target to be completed, and a ship alignment method based on ship AIS and ship stage data is provided for this purpose.
