step four: when the first winding and unwinding drum and the second winding and unwinding drum reach the length of the collected wire, stopping rotating;
step five: when charging is finished, a motor drives a power wheel shaft to drive a driven wheel to control a first winding and unwinding reel and a second winding and unwinding reel to rotate towards the other direction and start winding, a first transition reel and a second transition reel which are fixedly connected with the first winding and unwinding reel and the second winding and unwinding reel respectively rotate in the same direction, and meanwhile, input power of an auxiliary power end drives a power main shaft and two sets of universal lead frames to rotate in opposite directions with the first transition reel and the second transition reel, so that the transfer of two cables in opposite directions with three phases in the steps between the first transition reel and the first fixed reel as well as between the second transition reel and the second fixed reel in the double-cable winding and unwinding device is realized, and the normal work of a far end and a near end of the cable outside the device is not influenced;
step six: when the cable is completely withdrawn, the power wheel shaft and the power main shaft stop rotating, and one period of operation is finished.
6. The two-wire cable pay-off and take-up method according to claim 5, wherein: in the third step and the fifth step, the cables respectively extending from the interior of the first winding and unwinding drum and the interior of the second winding and unwinding drum to the first transition drum and the second transition drum respectively have two opposite winding modes, when the first transition drum and the second transition drum in a certain winding mode rotate in one direction to pay out, the universal lead frames rotating in opposite directions drive the paid-out cables to be respectively wound to the first fixed drum and the second fixed drum, and when the first transition drum and the second transition drum in a certain winding mode rotate in the other direction to take up cables, the two sets of universal lead frames rotating in opposite directions drive the cables to respectively separate from the first fixed drum and the second fixed drum one by one and to be respectively wound on the first transition drum and the second transition drum.
7. The two-wire cable pay-off and take-up method according to claim 5, wherein: the number of turns of the cable wound on the first winding and unwinding reel is the same as that of the cable wound on the second winding and unwinding reel.
