Problems solved by technology

However, because the existing technology relies on measured data, on the one hand, it takes a long time to accumulate sufficient data, and on the other hand, the collected measured data usually has a narrow range of parameters, so the applicable range of the established model is also narrow.

Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] At present, in the field of smart ships, the speed optimization algorithm has been continuously developed and applied. The algorithm flow is roughly as follows: ① When the ship is in operation, various data are collected in real time through sensors, including main engine power, shaft power, speed, displacement, water depth and various Class meteorological parameters. ② After...

Abstract

The invention provides a model construction method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps of obtaining first sample data of a ship,and determining the relation between the first sample data, wherein the first sample data is used for representing the performance of the ship; correcting the first sample data based on a preset correction formula and preset parameters to obtain second sample data; and constructing a shaft power model based on the second sample data. According to the invention, the applicability of the model canbe improved while the data collection time is shortened.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a model building method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In the design stage of a ship, it is generally necessary to consider the output power of the ship’s main engine and the rotational speed of the propeller under a certain speed condition; Forecasting problems. In the prior art, various types of data are usually collected by sensors in real time when the ship is in operation, and the relationship between the shaft power (or main engine power) and the speed, displacement, water depth and various meteorological parameters is determined after collecting enough data (ie shaft power model). However, because existing technologies rely on measured data, on the one hand, it takes a long time to accumulate sufficient data, and on the other hand, the collected measured data usually has a narrow range of parameters, ...
