The invention discloses a method for controlling steel wire rope winding, and belongs to the technical field of steel wire rope winding. The method comprises the steps of detecting the current rotating speed ndjjt of a crane drum, determining the real-time rope winding diameter Ddja of the crane drum, determining the real-time rope paying-off diameter Da of a steel wire rope drum, determining the rotating speed ns of a rotating motor according to the current rotating speed ndjjt of the crane drum, the real-time rope winding diameter Ddja of the crane drum, the real-time rope paying-off diameter Da of the steel wire rope drum and the speed reducer transmission ratio is of a rotating device, and controlling the rotating device to rotate at the rotating speed ns of the rotating motor. Through the technical scheme, the method can be used for adjusting the tightness of the steel wire rope winding by controlling the speed of the rotating device, and compared with the existing manual adjusting mode, the method saves more labor and is more accurate. Meanwhile, the invention discloses a system for controlling the steel wire rope winding. The system comprises a crane drum current rotating speed detecting module, a crane drum real-time rope winding diameter determining module, a steep wire rope real-time paying-off diameter determining module, a first processing module and a first control module.
