Overall planning method for track and speed of ship

Abstract

The invention provides an overall planning method for a track and a speed of a ship. The method is characterized by comprising the following steps, 1), a ship fuel consumption monitoring system is used for collecting ship instantaneous fuel consumption data which comprises data such as ship position reports in all previous voyages, the original data are cleaned, wrong data or inaccurate data are removed, and a ship instantaneous fuel consumption navigation big database is established; 2), an attribute reduction theory and a dependency degree algorithm in a rough set or a clustering and decision tree analysis method are used for finding relevant variables with the most important influence on fuel consumption from influence parameters such as wind, wave and flow; and 3), an instantaneous fuel consumption model of the ship is extracted, and a relation between the ship fuel consumption and navigation environment parameters such as the wind, the wave, the flow and the ship speed is found. According the ship track optimization method, the ship safe obstacle avoidance is considered, and the energy conservation and the like of the ship are considered by comprehensively considering the running working conditions of equipment such as a ship main engine and a ship auxiliary machine and the environment of a sea voyage, so that it is guaranteed that the ship can adapt to complex sea conditions and navigation environments to the largest extent.

Description

technical field [0001] The invention relates to the field of ship navigation control, in particular to a ship track optimization method. Background technique [0002] Ship track planning directly affects the energy consumption level of the ship. Due to the changeable sea environment of the ship on the sea route, if the ship follows the same route, it will lead to excessive fuel consumption. With the continuous development of shipping business, shipowners have increasingly stringent requirements for ship track planning, and traditional track planning technology only meets the needs of ship safety. It is of great engineering significance to design the optimal route according to the energy consumption of the ship, which can make the ship sail to achieve the most economical effect. On this basis, the dynamic planning of the ship's track is conducive to the development of the shipping economy and the full utilization of resources. [0003] With the rapid development of the shipp...

Problems solved by technology

In the actual ship transportation process, there is a direct relationship between wind speed, waves and other factors and fuel consumption, which affects the ship’s track planning. However, due to the complexity of the ship’s energy efficiency and the consideration , the dynamic adjustment of the ship's track is often overlooked
