Problems solved by technology

[0002] At present, in the process of ship navigation, due to some task requirements, the ship needs to be sailed to reach a specific location. The traditional method is for the navigator to manually calculate the motion plan based on the model knowledge on the paper chart, which is not only time-consuming and laborious. And it belongs to static calculation, the real-time performance is not high, and it is prone to human calculation errors

Embodiment Construction

[0027] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0028] A calculation method for nautical motion plotting based on electronic charts, such as figure 1 with figure 2 shown, including the following steps:

[0029] Step 1. Obtain the motion parameters of the target ship and the own ship, and superimpose and plot with the electronic chart information;

[0030] The concrete steps of described step 1 include:

[0031] (1) Collect radar sensor equipment, AIS equipment, simulated targets and fused target data in real time, obtain target motion parameters such as course, speed, azimuth, distance and time, and overlay and plot with electronic chart information;

[0032] (2) Real-time acquisition of sensors (GPS, log, wind speed and direction) to obtain the own ship's motion parameters including latitude and longitude, speed, course, wind speed and direction, and time, and superimpose plotting with elec...

Abstract

The present invention relates to a method for plotting and calculating navigational motions based on electronic charts. Its technical features include the following steps: step 1, acquiring target ship motion parameters and own ship motion parameters; step 2, selecting corresponding navigational motions according to navigation purposes The calculation model sets the navigation purpose parameters; step 3, real-time calculation of the ship's navigation movement command parameters; step 4, superimposing the navigation situation information of the own ship and the target ship based on the electronic chart information; step 5, according to the ship's motion parameters, operability and electronic charts The information calculates the rationality of the parameters of the own ship's navigation motion command; step 6, adjust the navigation purpose parameter according to the calculated rationality of the own ship's navigation motion command parameter, and then recalculate until it is reasonable. The present invention is based on the electronic chart information, according to the real-time motion parameters of the own ship and the target, applies the navigation motion calculation model, can quickly, conveniently, intuitively and real-time plot and calculate the navigation motion, and provides an auxiliary decision-making scheme.

Description

technical field [0001] The invention belongs to the technical field of navigation and navigation, and relates to a navigation motion plotting calculation method, in particular to a navigation motion plotting calculation method based on an electronic chart. Background technique [0002] At present, in the process of ship navigation, due to some task requirements, the ship needs to be sailed to reach a specific location. The traditional method is for the navigator to manually calculate the motion plan based on the model knowledge on the paper chart, which is not only time-consuming and laborious. Moreover, it belongs to static calculation, the real-time performance is not high, and human calculation errors are prone to occur. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide an electronic chart-based calculation method for navigational movement plotting that is reasonably designed and capable ...
