Abstract

The invention discloses a control river reach ship water supply and drainage judgment method based on a grid reference course, and belongs to the field of intelligent shipping and ship navigation application. The method comprises the following steps: on the basis of a calculation range of a control river reach and coordinates of a channel mileage line, gridding the control river reach and establishing an index by combining the actual condition of the control river reach and the advantages of a two-dimensional array, and calculating the position of a grid distance close to the channel mileage line by taking a grid center point as a coordinate; and then calculating the reference course of each grid by using the reference course of the channel mileage line. Through the method, the longitude and latitude of the ship AIS in the control river reach are subjected to coordinate change to obtain the grid index, the grid reference course is used for ship water supply and drainage judgment, a command system is provided for commanding, a powerful basis is provided for ship commanding in a channel, the working efficiency and accuracy of the command system are improved, and safe navigation of the ship is guaranteed.

Description

technical field

[0001] The invention belongs to the application field of intelligent shipping and ship navigation, and in particular relates to a method for judging the launching and launching of ships in river sections based on grid reference course. Background technique

[0002] The Yangtze River is the largest river in China and is known as the "Golden Waterway". The Yangtze River route starts from Shuifu Port in Yunnan Province and ends at the mouth of the Yangtze River, with a total length of 2,838 kilometers. It has formed an overall pattern that radiates the entire river basin with major national ports as the backbone and regional important ports as the basis. It has formed a relatively complete container, iron ore The river-sea transshipment system of stone and coal, as well as the specialized transportation system of automobile ro-ro and liquefied products, is the only large waterway transportation channel running through the eastern, central and western regions of m...
