Abstract

The invention relates to a transport ship transshipment characteristic information extraction method. The method comprises the following steps: obtaining ship position data of a transport ship and a fishing boat; searching time slots of all ships with navigation speed less than preset values; determining starting time and ending time of each voyage of the transport ship based on the time periods when the voyage speed values of all the transport ships are smaller than a preset value, and obtaining the time periods when the voyage speed values of all the voyages are smaller than the preset value; finding out a time period overlapped with the track of the fishing boat in time periods of which the navigational speed values are smaller than a preset value in each voyage; and outputting information corresponding to a time period overlapped with the track of the fishing boat. Transfer characteristic information of the transport ship can be extracted from Beidou ship position data.

Description

technical field [0001] The invention relates to the technical field of application of fishing vessel position data, in particular to a method for extracting characteristic information of a transport vessel. Background technique [0002] The catch transport ship (hereinafter referred to as the transport ship) is a kind of fishing auxiliary ship, which can provide supplies and reload catches for multiple fishing ships at the same time. The reloading of fish catches by transport ships is generally at sea far from the port, and the reloading location is the place where the catches are reloaded after the transport ships and fishing boats meet at sea. The transport ship can save the voyage time of the marine fishing motorized fishing boat (hereinafter referred to as the fishing boat) to and from the fishing port, reduce fuel consumption, increase the operating time, and improve the operating efficiency of the fishing boat, but it also increases the fishing intensity of the fishing...
