Problems solved by technology

The existing method of manually drawing the main track line draws according to the direction of the river without considering the actual navigation of the ship, and there is a certain error in the direction drawn manually, and the direction of the water flow in the channel is complicated, which will also affect the actual direction of the ship's navigation. The accuracy of this judgment method using the tangent direction of the track line as the navigation judgment direction is not high

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail:

[0035] This example takes the Shenbeizui controlled river section of the Luzhou section of the Yangtze River as an example to illustrate the implementation plan. By determining the calculation range and grid spacing of the controlled river section, the controlled river section is gridded and indexed, and the waterway is entered through the electronic waterway map. Mileage coordinates, calculate and store the specific position of the grid in the control river section, and then calculate the reference heading of the grid through the reference heading of the channel mileage line. The system only needs to convert the analyzed ship position data into a grid index, and then it can obtain the reference heading of the grid where the ship is located to judge the ship's launching and launching, and provide help for ship command, such as figure 1 As shown, the sp...

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...
