The invention discloses a hydraulic mooring device constant tension control method and system for ship mooring. The method comprises the steps that historical external disturbing force data of a hydraulic mooring device and a ship mooring rope are obtained; according to the historical external disturbing force data, training to obtain a disturbing force prediction model, and according to the disturbing force prediction model, obtaining an external disturbing force after the control valve is adjusted for a preset delay time; and inputting the external disturbing force into a preset fuzzy PID controller to obtain the opening degree of a control valve, and performing constant tension control on the hydraulic mooring device according to the opening degree of the control valve. The opening degree of the control valve of the hydraulic mooring device can be adjusted according to external disturbance force, so that tension fluctuation of a ship mooring rope is reduced, the situation of economic loss caused by breakage of the mooring rope or collision between a ship and a wharf during mooring is reduced, the mooring safety and reliability are improved, and the hydraulic mooring device can be widely applied to the technical field of ship safety.

    本发明公开了一种用于船舶系泊的液压系泊装置恒张力控制方法及系统,方法包括:获取所述液压系泊装置和船舶系泊缆绳的历史外部干扰力数据;根据所述历史外部干扰力数据训练得到干扰力预测模型,根据所述干扰力预测模型得到调节所述控制阀延时预设时间后的外部干扰力;将所述外部干扰力输入预设的模糊PID控制器,得到控制阀开度,根据所述控制阀开度对所述液压系泊装置进行恒张力控制。本发明能够根据外部干扰力调节液压系泊装置的控制阀开度,以降低船舶系泊缆绳的张力波动,并降低因系泊缆绳断裂或系泊时船舶与码头碰撞造成的经济损失的情况发生,提升系泊安全性和可靠性,可广泛应用于船舶安全技术领域。
