The invention provides an anti-overturning early warning method for an automobile crane, and belongs to the technical field of automobile cranes, and the anti-overturning early warning method for the automobile crane comprises the following steps: S10, collecting the working pressure of each supporting leg of the automobile crane through a pressure sensor; s20, the relative position of each supporting leg is collected through a distance sensor, and the relative coordinate of each supporting leg is determined; s30, based on the working pressure and the relative coordinates of all the supporting legs, the equivalent gravity center of the automobile crane is determined; s40, a threshold value is set according to the warning line, coordinates of all points in a warning area are determined on the basis of the relative coordinates of all the supporting legs, and then the warning area is obtained.The invention further provides a system for achieving overturning prevention of the automobile crane, stress of all the supporting legs and the automobile body posture of the automobile crane can be monitored in real time, and the gravity center position of the whole automobile is calculated and displayed in real time; an operator can observe the working condition of the whole vehicle more visually, and the problem that an existing moment limiter does not have the overturning early warning capacity and cannot effectively conduct early warning in advance is solved.

    本发明提供一种汽车起重机防倾覆预警方法,属于汽车起重机技术领域,一种汽车起重机防倾覆预警方法,包括以下步骤:S10:通过压力传感器采集所述汽车起重机各支腿的工作压力;S20:通过距离传感器采集各支腿的相对位置,并确定各支腿的相对坐标;S30:基于各支腿的工作压力和相对坐标,确定汽车起重机的等效重心;S40:根据警戒线设定阈值,并基于各支腿的相对坐标,确定警戒区域各点坐标,进而得到警戒区域,本发明还提供一种实现汽车起重机防倾覆的系统,本发明能够实时监测汽车起重机各支腿受力和车身姿态,计算整车重心位置并实时显示,让操作者更加直观的观测整车工况,以解决现有力矩限制器无倾覆预警能力,不能有效提前预警的问题。
