Abstract
The present application discloses a control method, a control system, and a device for a grab of a portal crane. The control method for a grab of a portal crane includes: acquiring a height information of the grab; acquiring an amplitude variation information of a luffing mechanism; acquiring a slewing angle information of a rotation of a slewing mechanism; determining a horizontal relative position information of the grab relative to a center point of the slewing mechanism according to the amplitude variation information and the slewing angle information; determining an actual position information of the grab relative to the center point of the slewing mechanism according to the horizontal relative position information and the height information; acquiring a scanning information of a hull, and determining a position information of a material; and planning an operation route of the grab.
