Abstract

The invention relates to an iterative calculation method for a ship draught difference, and belongs to the technical field of ship operation process calculation methods. According to the technical scheme, the method comprises the steps that (1) ship parameters are input into a system before ship operation; and (2) in the operation process, the shore machine loads and unloads goods at different positions of each cabin, the PLC reads the real-time position of the cart mechanism to obtain x _ n, reads the flow data of the belt weigher to obtain P _ n, automatically calculates the drainage duration t _ B, and can calculate the draught difference t in real time through sequential iteration. The method has the beneficial effects that the working relation between the ship and the shore machine isestablished through ship data input before operation and data collection of the belt weigher and the cart encoder in the operation process, so that the shore machine masters the ship trim condition in real time, and the method is free of any hardware cost investment, high in calculation speed and high in applicability.

Description

technical field [0001] The invention relates to an iterative calculation method for ship trim, and belongs to the technical field of calculation methods for ship operation processes. Background technique [0002] In recent years, smart port application technology has developed rapidly. The research content of smart port is extensive, and the calculation and control of ship's trim in the working relationship between shore machine and ship is an important topic. During the loading and unloading process, the status of the ship changes in real time, and the hardware detection technology is not yet mature, which restricts the development of intelligent ship loading and unloading. For intelligent loading, it involves the calculation of the ship’s trim during the relocation stage and the real-time control of the ship’s trim during the loading process; for intelligent unloading, it involves the calculation of the ship’s trim during the tank adjustment process and the real-time cont...
