The invention discloses a method for lowering a wing-shaped sail decided by wind speed. The method comprises the following steps of: respectively arranging a bow draft sensor and a stern draft sensor at the bottoms of a bow and a stern of a ship, establishing a ship body coordinate system, monitoring the relative wind speed of a sail top in real time, judging the difference value between the artificially set wind speed and the relative wind speed, and lowering the sail surface section by section. According to wing-shaped sail boosting devices with different sections, the posture of a ship in the marine environment, the distance between the highest point of the sail and the horizontal plane and the real-time wind speed are considered, sail lowering control strategies suitable for different wind speeds are established, the maximum use time can be provided for the sail with multiple sections, and the use efficiency of the sail is improved. Through alarm when the wind speed does not reach the limit value, buffering is provided for sailors, meanwhile, sail descending is directly conducted when the limit value is reached, safety guarantee is provided for the sail, and the optimal sail descending control strategy is achieved based on the sail top wind speed.
一种由风速决定的翼型风帆降帆方法,在船舶艏部、艉部的底部分别设置有艏吃水感应器和艉吃水感应器,建立船体坐标系,实时监测风帆顶的相对风速,对人为设定风速与相对风速的差值进行判断,对帆面进行逐节下降。针对不同节数的翼型风帆助推装置,考虑了船舶在海洋环境中的姿态、风帆最高点距水平距离以及实时风速,建立了适用于不同风速的降帆控制策略,可为多节数风帆提供最大的使用时长,增加了风帆的使用效率。通过未达到风速限值时的报警,为船员提供了缓冲,同时在达到限值时直接降帆,为风帆提供了安全保障,基于帆顶风速实现了最优的降帆控制策略。
