The invention discloses a method and a system for determining the lifting height of a floating crane. The method comprises the following steps: acquiring the reading of an absolute value encoder on a main hook winding drum side and the absolute angle of a boom; determining a reel release layer according to the reading of the absolute value encoder; according to the reel release layer, determining the residual rope capacity of the reel layer and the diameter of the reel release layer steel wire rope winding the reel by one circle; determining the residual rope capacity of the reel release layer according to the diameter of the reel release layer steel wire rope around the reel; subtracting the residual rope capacity of a reel release layer and the residual rope capacity of a reel layer from the highest lifting height, and then subtracting the height of a hook head body to obtain an initial lifting height; according to the absolute angle of the arm support, the lifting compensation height caused by the absolute angle change of the arm support is determined; the sum of the initial lifting height and the lifting compensation height caused by the absolute angle change of the arm support is the final lifting height of the crane. Accurate calculation of the lifting height is achieved.

    本发明公开的一种浮式起重机起升高度确定方法及系统,包括:获取主钩卷筒侧绝对值编码器读数和臂架绝对角度;根据绝对值编码器读数,确定卷筒释放层;根据卷筒释放层,确定卷筒层剩余容绳量和卷筒释放层钢丝绳绕卷筒一圈的直径;根据卷筒释放层钢丝绳绕卷筒一圈的直径,确定卷筒释放层的剩余容绳量;将最高起升高度减去卷筒释放层的剩余容绳量和卷筒层剩余容绳量后再减去钩头本体高度,获得初始起升高度;根据臂架绝对角度,确定臂架绝对角度变化引起的起升补偿高度;初始起升高度与臂架绝对角度变化引起的起升补偿高度之和,为最终的起重机起升高度。实现了对起升高度的准确计算。
