Abstract:
1. A stability control system for an engineering machine comprises a detection device, a control device and an alarm device wherein: the detection device detects the current center-of-gravity positions of each component of the engineering machine to obtain the center-of-gravity position signals of each component and transmits the center-of-gravity position signals to the control device; the control device receives the center-of-gravity position signals from the detection device, calculates the center-of-gravity position of the engineering machine according to a center-of-gravity calculation strategy, and compares it with a preset balance range wherein the control device controls the alarm device for warning when the center-of-gravity position of the engineering machine exceeds the balance range; the balance range ensures that the supporting point of legs of the engineering machine is in the projection point in horizontal plane, the area formed by the connecting line of two adjacent projection points passes through the safe area upon the first safety calculation, and the center-of-gravity position of the engineering machine is the position of the center-of-gravity projection point of the center-of-gravity of the engineering machine in horizontal plane passing through the safety point upon the second safety calculation.
