Automatic piling control system and automatic piling control method
The invention discloses an automatic piling control system and an automatic piling control method. The automatic piling control method comprises the steps of according to the actual depth of mud entering after a pile is hammered before the mth hammering of the jth pile, calculating to obtain the accumulated depth of mud entering of the pile before the mth hammering of the jth pile; through a multiple linear regression equation model, fitting a mathematical relationship between piling resistance borne by the jth pile when the pile is located at any depth and the mth hammering of the jth pile reaches any target mud entry depth; predicting an estimated value of hammering energy required when the mth hammering of the jth pile reaches a target mud-entering depth according to the calculated accumulated mud-entering depth of the pile and the mathematical relationship between the mth hammering of the jth pile reaching the target mud-entering depth and the piling resistance when the pile is ata depth; and controlling a pile hammer to pile according to the predicted estimated value of the hammering energy.
本申请公开自动打桩控制系统和自动打桩的控制方法，其中自动打桩的控制方法包括以下步骤：根据第j根桩的第m次锤击前的所述桩被锤击后入泥的实际深度，计算得到第j根桩的第m次锤击前，所述桩累计入泥的深度；通过多元线性回归方程模型，拟合所述桩处于任一深度时，第j根桩的第m次锤击达到任一目标入泥深度所受打桩阻力之间的数学关系；根据计算得到的所述桩累计入泥的深度和所述桩处于一深度时，第j根桩的第m次锤击达到一目标入泥深度与打桩阻力之间的数学关系，预测第j根桩的第m次锤击达到所述目标入泥深度时，所需要的锤击能量的预估值；根据预测的所述锤击能量的预估值控制打桩锤打桩。
