Problems solved by technology

In order to solve the problem that massive ship position data occupies a large amount of memory resources and the time efficiency of finding ships that meet the rescue conditions is relatively low, a method is needed to quickly find the nearest and closest ships to the wrecked ship to carry out rescue, and further improve the implementation of ship rescue at sea. efficiency and effectiveness

Embodiment Construction

[0036]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.

[0037] The embodiment of the present invention relates to an effective rescue and search method for ships at sea based on the gridded neighborhood, which performs gridded encoding on the longitude and latitude of the ship's position, and converts the two-dimensional coordinates into one-dimensional string encoding; on this basis, according to The effective rescue distance is set, and the adjacent ships of the wrecked ship are se...

Abstract

The invention relates to a gridding neighborhood-based marine ship effective rescue search method, which comprises the following steps of: performing gridding encoding on ship position data, storing agridding encoding result, and representing two-dimensional longitude and latitude space information of a ship by using encoded one-dimensional character string data; receiving position information ofthe wrecked ship, and determining a grid code corresponding to the wrecked ship based on the position information; searching ships meeting effective rescue distance conditions in neighborhoods of thewrecked ships according to the grid codes, and finding out to-be-selected rescue ships; and searching the nearest ship from the to-be-selected rescue ships as a priority rescue ship. A nearest ship and a closer ship of the wrecked ship can be quickly found.

Description

technical field [0001] The invention relates to the technical fields of maritime rescue and spatial information, in particular to an effective rescue search method for marine ships based on gridded neighborhoods. Background technique [0002] With the frequent occurrence of extreme weather events, the frequency of marine disasters is increasing year by year; at the same time, due to the continuous improvement of my country's economic extroversion, maritime transportation has entered a period of rapid development, and sea routes are dense. The sea navigation and operation environment of fishing vessels is becoming more and more complex. Compared with other ships, fishing boats are less capable of resisting marine natural disasters and preventing traffic and production accidents. Various marine accidents such as self-sinking, wind damage, contact damage, and collisions of fishing boats occur from time to time, posing a serious threat to the lives and property of fishermen. . ...
