The invention relates to the field of engineering machinery, and provides an anti-rollover early warning method and an anti-rollover early warning system for an operation machinery, and the operation machinery, and the method comprises the following steps: obtaining the whole vehicle gravity center position and the whole vehicle mass of the operation machinery, the inclination angle of the operation machinery relative to the horizontal plane, and the walking acceleration of the operation machinery; and a supporting point position of the working machine on the inclined working surface. Calculating a first moment and a second moment; when it is determined that the first moment is larger than or equal to the second moment, alarm prompt information is sent out, and the alarm prompt information indicates that the operation machine has the overturning risk. According to the arrangement, the key parameter information of the working machine in the moving working process is obtained, real-time analysis and judgment of dynamic stress of the working machine are achieved, and therefore accurate pre-judgment of the overturning risk is achieved, manual intervention judgment is not needed, the probability of overturning accidents is reduced, and the safety performance of the working machine in the working process is improved.

    本发明涉及工程机械领域,提供一种作业机械的防侧翻预警方法及防侧翻预警系统、作业机械,包括:获取作业机械的整车重心位置和整车质量,作业机械相对于水平面的倾斜角度,作业机械的行走加速度,以及作业机械在倾斜作业面上的支撑点位置;计算第一力矩和第二力矩;当确定第一力矩大于或等于第二力矩时,发出报警提示信息,报警提示信息表示作业机械存在倾覆风险。如此设置,通过获取作业机械在移动工作过程中的关键参数信息,实现对作业机械动态受力的实时分析与判断,从而实现对倾覆风险的精准预判,无需人为介入判断,降低了倾翻事故发生的可能性,提高了作业机械作业过程中的安全性能。
