Ship-shore satellite link construction and operation method based on polar sea area fishery service system

Abstract

The invention discloses a ship-shore satellite link construction and operation method based on a polar sea area fishery service system, and the method comprises the following steps: (1) carrying out the projection of a high-latitude or polar sea area through employing a polar coordinate projection mode, and carrying out the asymmetric spacing grid division of a fishing ground area; (2) performing thematic map publishing on the fishery condition elements by a publishing technology; (3) the shore-based fishery service terminal compresses the made graphic and text information and then sends the graphic and text information to the iridium satellite constellation network every day, and the graphic and text information is sent to the ship-based fishery service terminal through the iridium satellite transmission terminal; and (4) the operation ship feeds back to the ship-end fishery service terminal according to the actual offshore production condition. Based on ship-shore double-link intercommunication, a new method is provided for operation and release of a polar region fishery service system, the functions of ship-base-shore-base and shore-base-ship-base two-way link satellite communication are achieved, and the fishing assisting functions such as receiving and displaying of a krill system fishery fishing condition product map from a shore base to a ship end, fishery decision making and commanding are achieved.

Description

technical field [0001] The invention relates to the field of marine fishery system services, in particular to a method for building and operating a ship-to-shore satellite link of a polar sea area fishery service system. Background technique [0002] Since my country started Antarctic krill exploration in 2009, the scale of Antarctic krill exploration has expanded steadily, and a series of results have been achieved. There have also been major breakthroughs in key technologies such as fishing gear, fishing methods, and product processing that restrict the development of my country's Antarctic krill industry. [0003] However, with the gradual development of Antarctic marine biological resources and the scarcity of satellites in orbit in the polar region, information such as sea conditions, fishing conditions, and weather in the operating area need to be transmitted to the ship's end in a timely manner, and some sonar, pictures and other data on the ship's end also need to be ...

Problems solved by technology

[0003] However, with the gradual development of Antarctic marine biological resources and the scarcity of satellites in orbit in the polar region, information such as sea conditions, fishing conditions, and weather in the operating area need to be transmitted to the ship's end in a timely manner, and some sonar, pictures and other data on the ship's end also need to be transmitted in time To the shore system, however, there is no related research and technology realization at home and abroad

Therefore, the two-way interconnection of ship-side and shore-side data transmission has become an urgent problem. At the same time, construct a commercial operation method and case demonstration based on the fishery service system to improve the ship-shore satellite link guarantee and fishery prediction and analysis capabilities in polar seas It is extremely important for the safe production of enterprise fishing boats, but related methods have not been reported yet
