The invention relates to an automatic anti-swing control method for a marine crane, and belongs to the technical field of marine cranes. The automatic anti-swing control method comprises the following steps: mounting an attitude sensor on the marine crane, and acquiring rolling and pitching attitude data of a ship in real time by using the attitude sensor; calculating the displacement of a lifting point at the front end of the rhombic mechanism in an absolute coordinate system according to space coordinate conversion; the real-time position where the lifting point needs to reach is calculated according to the displacement, a first telescopic power device and a second telescopic power device of the compensation mechanism are controlled to act to compensate the rhombic mechanism, the influence of ship swing on the lifting point displacement is eliminated, the lifting point is kept relatively static in an absolute coordinate system, and the swing angle of a heavy object is reduced. The automatic ...

The invention provides a hoisting equipment load posture recognition method and system, and belongs to the technical field of hoisting equipment load posture recognition. In the process that hoisting equipment hoists a load, in order to carry out anti-swing control on the load, a load posture needs to be obtained. At present, load posture acquisition through a mechanical sensor has the problems of steel wire rope twisting, guide wheel clamping stagnation and the like, and load posture acquisition is affected. In the hoisting process, the hoisting point coordinate system is determined by taking the hoisting point as an original point, and the rotation angle of the load rotating around the hoisting point coordinate system is obtained, so that the position of the load in the hoisting point coordinate system is determined. And then rotating conversion of positions between the two coordinate systems can be realized by utilizing an included angle between corresponding coordinate axes of the control ...
