Monitoring device and construction machine
A monitoring device calculates, on the basis of shape data, a first slope angle that is the inclination angle of a slope with respect to a ground contact surface of a construction machine; detects a ground contact surface angle that is the inclination angle of the ground contact surface with respect to a horizontal surface; adds the first slope angle to the ground contact surface angle so as to calculate a second slope angle that is the inclination angle of the slope with respect to the horizontal surface; calculates a relative angle, with respect to the slope inclination direction, in the longitudinal direction of a lower-part traveling body; and determines that the construction machine is in an unstable state when the second slope angle is greater than a first threshold value and the relative angle is greater than a second threshold value.
一种监控装置，基于形状数据计算坡面相对于工程机械的接地面的倾斜角度即第一坡面角度；检测接地面相对于水平面的倾斜角度即接地面角度；将第一坡面角度与接地面角度相加，计算坡面相对于水平面的倾斜角度即第二坡面角度；计算下部行走体的长度方向相对于坡面的倾斜方向的相对角度；在第二坡面角度大于第一阈值并且相对角度大于第二阈值的情况下，判断工程机械处于不稳定状态。
