[0036] See figure 1 Is a flowchart of the first embodiment of the ship speed control method provided by the present invention, and the method includes:

[0037] Step S11: Obtain ship operating parameters and environmental state data. Wherein, the ship operating parameters may include current speed, current output power, current load, etc., and the environmental state data may include current wind direction and wind speed, and current water flow direction and velocity.

[0038] Step S12. Calculate the optimal speed range based on the vessel operating parameters and environmental state data, where the optimal speed range is the most economical and safe speed range under current conditions, which can ensure the safety of the ship’s navigation and save fuel to the utmost extent. For shipping costs, enhance shipping competitiveness.

[0039] Step S13: Control the sailing speed of the ship according to the optimal speed range. For example, the optimal speed range can be provided to the c...

[0041] See figure 2 Is a flowchart of the second embodiment of the ship speed control method provided by the present invention, and the method includes:

[0042] Step S21: Construct a database based on the historical data of the ship itself and the historical data of the same type of ship from the shared platform, wherein the database includes the optimal speed range corresponding to the discrete ship operating parameter-environmental state data combination. Among them, the database can be updated regularly, for example automatically before the start of each voyage.

[0043] Step S22: Obtain ship operating parameters and environmental state data. Wherein, the ship operating parameters may include current speed, current output power, current load, etc., and the environmental state data may include current wind direction and wind speed, and current water flow direction and velocity.

[0044] Step S23: According to the currently acquired ship operating parameters and environmental sta...

Description

Technical field [0001] The invention relates to the field of navigation, and in particular to a method and system for controlling ship speed. Background technique [0002] The integrated automation of ships has attracted more and more attention, and speed control is an important part of it. When a ship is sailing at sea, the speed of the ship will inevitably change due to external disturbances such as wind, waves and currents. At present, the speed control of most ships is actually open-loop control. It is not easy to do this and it is not easy to control the speed of the main engine manually. Automatic control of ship speed is very necessary. It is of practical significance for both military and civilian ships. It can improve the maneuverability of ships, save fuel, and reduce operating costs. Summary of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a ship speed control method and system, which overcomes the ...
