Control method and device for cooperative operation of double cranes and double-crane system

The embodiment of the invention provides a control method and device for collaborative operation of double cranes and a double-crane system, and belongs to the technical field of double-crane operation. The control method comprises the following steps: decomposing an operation action of a main crane under a preset operation type into a plurality of reference actions, and determining an operation parameter value of an auxiliary crane under each reference action according to each working condition parameter, corresponding to each reference action, of the main crane and initial position parameters of the main crane, the auxiliary crane and a load, and determining a target operation parameter value of the auxiliary crane, and controlling the auxiliary crane based on the target operation parameter value. According to the invention, the double-crane operation steps can be preset in advance, and a double-crane collaborative operation control method is provided for the operation actions of the double cranes in differ
