Abstract

The invention discloses a cable drum control method and a cable drum control device. The method comprises the following steps of positioning and calculating the relative distance between a shore cabledrum and a wharf boat power connection box; calculating the actual length of a cable; measuring the tensile force borne by the cable; and judging the stress of the cable, wherein if the tensile forceborne by the cable exceeds a normal range, the winding and unwinding of the cable are controlled according to the deviation between the actual length of the cable and the relative distance. By introducing a cascade control system and using the stress of the cable as a given value for cable length adjustment, the length of the cable can be adjusted according to the stress of the cable, disturbancegenerated by a sudden stress change of the cable is overcome, and the problem of insufficient GPS precision is solved.

Description

technical field [0001] The invention relates to the technical field of cable reels, in particular to a method for controlling a cable reel and a control device for a cable reel. Background technique [0002] In recent years, with the continuous and rapid development of the national economy, the pace of port construction has become faster and faster. As a technology that can effectively reduce the discharge of pollutants in ports, the use of shore power for ships has attracted more and more attention. In order to realize the transmission of electricity from the shore to the ship, it is necessary to connect the cable across the river to the barge connection box. The cable length needs to be adjusted according to the position of the barge on the water. In the cable reel control system, how to control the retraction and release of the cable according to the position information from the shore connection box to the pontoon has become an inevitable problem in the shore power syst...
