Abstract (en)

[origin: EP3907336A1] A monitoring system calculates, based on a contour data, a first slope angle representing an inclination angle of a slope to a ground surface on which a construction machine stands, detects a ground surface angle representing an inclination angle of the ground surface to a horizontal plane, calculates a second slope angle representing an inclination angle of the slope to the horizontal plane by adding the first slope angle to the ground surface angle, calculates a relative angle of a longitudinal direction of a lower traveling body to an inclination direction of the slope, and determines that the construction machine is in an unstable state when the second slope angle is larger than a first threshold and the relative angle is larger than a second threshold.
