The invention provides a method and a system for controlling a support device of a construction machine. The method comprises the steps that under the condition that a supporting device of the engineering machine reaches a target position state, a to-be-adjusted target supporting leg is determined according to the characteristics of the inclination angle of the engineering machine in the preset direction; determining a target current value for adjusting a proportional valve of the target supporting leg according to a size relationship between a first inclination angle between the engineering machinery and the horizontal plane in the first preset direction and a second inclination angle between the engineering machinery and the horizontal plane in the second preset direction; performing leveling control operation on the target supporting leg based on the target current value; the first preset direction and the second preset direction are perpendicular to each other to form a rectangular plane coordinate system with the gravity center of the engineering machinery as the original point. According to the control method, the direction with the large deviation can be adjusted in a targeted mode, the leveling control efficiency and stability of the supporting device are effectively improved, and therefore the safety of the engineering machinery during operation is improved.

    本发明提供一种工程机械的支撑装置的控制方法及系统。该方法包括:在工程机械的支撑装置达到目标位置状态的情况下,根据工程机械在预设方向上倾斜角度的特征确定待调整的目标支撑腿;根据工程机械在第一预设方向上与水平面之间的第一倾斜角度和在第二预设方向上与水平面之间的第二倾斜角度之间的大小关系,确定调整目标支撑腿的比例阀的目标电流值;基于目标电流值对目标支撑腿进行调平控制操作;第一预设方向和第二预设方向相互垂直,构成以工程机械的重心为原点的平面直角坐标系。本发明提供的控制方法,能够针对性的调整偏差较大的方向,有效提高了支撑装置进行调平控制的效率和稳定性,从而提高了工程机械运行时的安全性。
