Embodiment Construction

[0025] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0026] The embodiment of the present invention relates to a method for extracting voyages based on ship position data, comprising the following steps: buffering outwards from the port where the ship departs and returns, as well as the land and islands where the port is located, to form a buffer surface; obtaining the position track of the ship , the intersection point generated by the intersection of the ship's position traject...

Abstract

The invention relates to a method of extracting a voyage number based on vessel position data, which comprises the following steps: outward buffer is carried out on a port for departure and return of a vessel and the land and the island where the port is located, and a buffer face is formed; the position trajectory of the vessel is acquired, a crossing point where the position trajectory of the vessel and the buffer face cross is the departure position of the return position of the vessel, the process between two crossing points is one voyage number, and all voyage numbers are acquired through sequencing according to the time sequence. Voyage numbers of the vessel can be extracted in real time, rapidly, automatically and in a large range.

Description

technical field [0001] The invention relates to the technical field of ship position data mining, in particular to a method for extracting voyages based on ship position data. Background technique [0002] Vessel Monitoring System (VMS, Vessel Monitoring System) can provide ship time, location and dynamic information. At present, nearly 50,000 Chinese fishing boats are equipped with automatic identification equipment (AIS), nearly 50,000 Beidou satellite ship position monitoring, and 110,000 CDMA public mobile communication equipment. ship, initially realizing real-time contact and tracking monitoring of the position of ocean fishing vessels. There are many ways to record voyages, such as: (1) manual recording of voyages and survey points in the voyage during the survey; (2) design of voyages according to the shortest distance and optimal route in route planning; (3) voyages In the management, the voyage is entered and managed by the computer. These voyage recording method...
