Abstract

The invention relates to an iterative calculation method for ship trim, belonging to the technical field of ship operation process calculation methods. The technical scheme of the present invention is as follows: (1) before the ship operates, the ship parameters are entered into the system; (2) during the operation, the shore machine loads and unloads goods at different positions in each cabin, and the PLC can read the real-time position of the cart mechanism to obtain x_n, read Taking the flow data of the belt scale, P_n can be obtained, and the drainage time t_B can be automatically calculated. Through successive iterations, the draft difference t can be calculated in real time. The beneficial effects of the present invention are: through the data entry of the ship before the operation, the data collection of the belt scale and the cart encoder during the operation, the working relationship between the ship and the shore machine is established, so that the shore machine can grasp the trim situation of the ship in real time. Without any hardware cost investment, the calculation speed is fast and the applicability is strong.

Description

technical field [0001] The invention relates to an iterative calculation method for ship trim, belonging to the technical field of ship operation process calculation methods. 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 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 ship loading, it involves the calculation of the ship's trim during the tank-moving 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 adjustment process and the real-time control of th...
