Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] When the power generated by the main engine of the ship is constant, the speed of the ship depends on the resistance it suffers. When a ship sails in flowing water, as long as the speed of the ship is equal to the speed of sailing in still water, the resistance it suffers is the least.

[0050] A ship travels a full voyage from point A to point B, and the ship will encounter resistance during its travel. Among them, water resistance and wind resistance are the main resistances encountered by the ship during its travel.

[0051] The water resistance suffered by a ship is related to the relative speed of the ship and water, and also related to the water receiving area; the wind resistance received is related to the relative speed of the shi...

Abstract

The invention discloses a method and device for controlling energy-saving sailing of a ship. The method comprises the steps of configuring the preset instantaneous oil supply amount of a main engine of the ship, and controlling the current opening degree of an accelerator to enable the preset instantaneous oil supply amount of the main engine of the ship to be unchanged during routing sailing. Compared with the prior art, the method and device have the advantages that energy waste is reduced greatly and sailing cost is reduced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of ship navigation, and in particular relates to a control method and device for energy-saving navigation of ships. [0003] 【Background technique】 [0004] With the development of our country and the world economy, the volume of logistics has been increasing, so the shipping market has also continued to grow and develop. For shipping companies, the cost of fuel oil is the main cost of the company's operations. Therefore, it is very important to study new technologies for energy-saving ship fuel to further save fuel consumption. It is very important to reduce ship operating costs and do a good job in energy conservation and emission reduction, which is of great significance to the development of enterprises and the protection of the natural environment. [0005] Oil is a major part of a ship's voyage expenses, so saving fuel is a very important aspect of ship improvement efforts. After saving fuel,...
