Problems solved by technology

For the time of fishing boats in port and out of port, the captain’s report or port RFID monitoring is generally used. Some fishing boats are not counted, and sometimes the information is not timely. Using the monitoring data of the fishing boat’s Beidou position can monitor the status of fishing boats in port and going out to sea. Calculating the length of time, there is no effective use of Beidou ship position data to analyze the time of fishing boats in port and out to sea.

Abstract

The invention relates to a method for analyzing in-port and sailing time of a fishing boat based on Beidou ship position data, comprising the following steps: extracting an anchored ship position according to the speed of the fishing boat, and screening out the anchored ship position data in each location; converting the ship position data into vector files and projecting; defining the dense pointin the location as the mooring port of the ship and marking the port, assigning the administrative division to the port location; judging whether the ship is in port or sailing in the sea by the relationship between the port location and the fishing boat; and extracting the sailing time and return time, and calculating a timetable for in-port and sailing time.

Description

technical field [0001] The invention relates to the technical field of ship position data mining, in particular to an analysis method for fishing boats in port and out to sea based on Beidou ship position data. Background technique [0002] Due to the continuous decline of offshore fishery resources, countries have paid more and more attention to the conservation of fishery resources, and the time of fishing boats in port and at sea is important information for research on fishery resources. The Beidou satellite navigation system has both positioning and information communication functions, and can provide fishing vessels with various valuable service information such as fishery policy notices and management regulations in text. The ship-borne Beidou satellite navigation system with two-way message communication and positioning functions can greatly meet the performance requirements of the fishing boat safety rescue information system for the ship-borne information terminal,...
