Ship trajectory-based message acquisition method and device, storage medium and equipment

The invention discloses a message obtaining method and device based on a ship trajectory, a storage medium and equipment, and the method comprises the steps: obtaining coordinate pair information in a ship continuous trajectory collected by a positioning instrument in a transmission period of a Beidou terminal, and extracting a first coordinate pair from the coordinate pair information, obtaining the passing time, the coordinate longitude value and the coordinate latitude value of the first coordinate pair; performing data conversion respectively; encoding the passing time, the coordinate longitude value and the coordinate latitude value of the first coordinate pair after data conversion to obtain a corresponding transmission message header; obtaining a longitude difference value and a latitude difference value between other coordinate pairs in the coordinate pair information and the first coordinate pair so as to obtain a corresponding transmission message style; and obtaining the transmission message accord
