The invention discloses a ship electronic water gauge measuring method and system. The method comprises the following steps: establishing a ship drawing size database; synchronizing the measuring nodes, and collecting a ship tail water level height value and angle values, angular velocity values and acceleration values of the front part, the middle part and the rear part of the two sides of the ship side in the trim direction at a unified measurement starting time point; based on dynamic data change characteristics of the angular velocity value and the acceleration value, extracting a measurement starting time point conforming to a ship equilibrium state, and establishing an equilibrium state data table by taking the measurement starting time point as an index; based on the equilibrium state data table and the ship drawing size database, a set of front, middle and rear water gauge values of the equilibrium state of the ship are obtained through calculation. According to the ship electronic water gauge measuring method disclosed by the invention, filtering calculation is carried out on the front, middle and rear water gauge values of the balance state corresponding to multiple repeated groups of different measurement starting time points, so that the measurement calculation precision can be further improved.

    本发明公开了一种船舶电子水尺测量方法及系统,包括建立船舶图纸尺寸数据库;同步各测量节点并以统一的测量起始时间点采集船舶尾部水位高度值以及船舷两侧前、中、后部的纵倾方向上的角度值、角速度值和加速度值;基于角速度值和加速度值的动态数据变化特征提取符合船舶平衡态的测量起始时间点,以此为索引建立平衡态数据表;基于平衡态数据表和船舶图纸尺寸数据库,分别计算得到船舶平衡态的一组前、中、后部水尺数值。根据本发明公开的船舶电子水尺测量方法,对重复多组的不同测量起始时间点对应的平衡态的前、中、后部水尺数值作滤波计算,可以进一步提升测量计算精度。
