Problems solved by technology
However, before the trial operation of the ship, it is necessary to set the parameters such as the speed and heading, the display mode, and the length of the vector line based on the navigation experience. The operation is cumbersome, and there is also great uncertainty in the final avoidance effect. The practicability is poor in large waters with variable course, and the application effect is not good
[0005] The traditional electronic chart or radar test ship has complex functions, the density of ships in the port is high, the practicability is poor in waters with variable course, and the application effect is not good

Embodiment Construction
[0054] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0055] It should be noted that, in the following specific embodiments, when describing the embodiments of the present invention in detail, in order to clearly show the structure of the present invention for the convenience of description, the structures in the drawings are not drawn according to the general scale, and are drawn Partial magnification, deformation and simplification are included, therefore, it should be avoided to be interpreted as a limitation of the present invention.
[0056] In the following specific embodiments of the present invention, an input module, a speed change avoidance calculation module and an output module are included;
[0057] The input module collects the navigation information of the ship and the target ship in real time, so that the collection time is 0 time, and the starting latitude and longitud...

The invention discloses a speed-changing and avoidance system for ships navigating in a channel. The navigation information of a target ship is collected in real time, and whether a collision will occur is judged according to the speed and course of the own ship and the target ship. Under the premise of the same heading, according to the expected meeting position of the own ship, only need to adjust the speed of the own ship without changing the course, and the collision avoidance can be realized, and the result can be displayed on the electronic chart in the form of images and / or numbers On the screen, the operation is simple and fast, and the display is intuitive.
Description
technical field [0001] The invention relates to the field of ship navigation, and more specifically, to a speed-changing avoidance system for ships navigating in waterways. Background technique [0002] The shortest time to closest point of approach (TCPA) and shortest distance to closest point of approach (DCPA) of two ships are two important factors that determine the collision risk of two ships. DCPA reflects the distance between two ships. The degree of risk of collision and TCPA reflects the urgency of the risk of collision between two ships. However, ships sail along their respective channels in the channel, and DCPA is not an important reference factor to measure the collision risk of ships. Before the ship passes the turning point of the channel, the driver needs to predict whether the own ship will meet the target ship at the turning point, and take measures to accelerate or decelerate to avoid this situation. [0003] Technicians have done a lot of research work ...
