Problems solved by technology

[0004] At present, the existing ship navigation speed control method cannot solve the above problems well, as described in CN111090911A "A kind of ship navigation speed energy-saving optimization auxiliary method", although it provides real-time adjustment of the navigation speed of the remaining section according to the wind and wave changes in the navigation area, However, it cannot judge the position of the propeller in the sea water and which stage the ship is in, so as to make accurate adjustments to the ship's sailing speed

Embodiment Construction

[0065] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] like Figure 1-5 As shown, a control method of a ship sailing speed control system under high wind and wave sea conditions, wherein the control system includes a propeller 1, a propeller installation main shaft 2, a thin-plate pressure sensor 71, a pressure sensor protective cover 4, a control system 5, and a main engine assembly of the ship. 6. Collection component 7 and operator 3;

[0067] The propeller 1 is installed on the propeller installation main shaft 2, the sheet pressure sensor 71 is fastened to the propeller installation main shaft 2 by bolts, and a pressure sensor protective cover 4 is provided on the outside of the thin film pressure sensor 71, and the pressure sensor protective cover 4 is bolted. It is fixedly connected to the main shaft 2 of the propeller installation;

[0068] The acquisition assembly 7 collects the da...

Abstract

The invention discloses a control method of a ship navigation speed control system under a heavy storm sea condition, the pressure of a propeller mounting main shaft is obtained through a pressure sensor to judge the state of a propeller in seawater, and the measurement and judgment process is simple and effective; the method is used for judging whether a ship is in a wind wave ascending stage or a wind wave descending stage through height changes of wave surfaces at different moments, different control strategies are adopted according to different wind wave stages of different ships, and the accuracy of ship navigation speed control is improved; by measuring the seawater density of different navigation sea areas, the critical pressure when the propeller is tangent to the sea level is determined, and meanwhile, the real-time flow speed and the real-time flow direction of ocean current are considered, so that the real-time performance and the applicability of the ship navigation speed control method are improved.

Description

technical field [0001] The invention belongs to the technical field of ship sailing speed control, and in particular relates to a control method of a ship sailing speed control system under strong wind and wave sea conditions. Background technique [0002] With the continuous development of the world trade economy, the shipping industry has become more and more important. Ship transportation is carried out every day, and due to the needs of trade competition, the speed and safety of ships have become more important. The changeable environment at sea, mainly refers to the strong wind and waves at sea, also greatly affects the navigation safety of ships. [0003] When the ship sails into the area with strong wind and waves, the ship will have more violent swaying motion, slowing down, unstable heading, and other difficulties in maneuvering caused by this, and even unpredictable dangers. For example, strong wind and waves will increase the sailing resistance of the ship, redu...
