AI Technical Summary

Technical Problem

Existing technologies suffer from low accuracy in ship load calculation, especially when the ship's condition changes or the water surface is uneven, making it difficult to accurately calculate the ship's load capacity.

Method used

The average draft of the ship's perimeter is obtained by a three-point detection method. Combined with temperature compensation and weighted correction algorithms of ultrasonic sensors, the ship's center of drift is determined by trigonometric function relationships. The ship's load capacity is calculated by linear interpolation, taking into account changes in ship state and water surface.

Benefits of technology

It improves the accuracy of ship load calculation, enables real-time assessment of ship energy efficiency levels, and adapts to the precise measurement needs of ships under different conditions.

Abstract

This invention discloses a method for real-time ship load calculation, relating to ship load calculation technology. It involves obtaining the ship's average draft from its periphery using a three-point detection method; determining the ship's center of buoyancy; and obtaining the average draft of the ship's trim based on the trigonometric relationship between the center of buoyancy and the midships; applying a weighted correction to the average draft of the ship to obtain the average draft; determining an interpolation interval based on the average draft; and calculating the ship's load capacity using linear interpolation. This invention provides highly accurate ship weight measurement; it enables real-time acquisition of ship load capacity, timely and effective assessment of ship energy efficiency, and has a wide range of applications.
