Abstract
A winch control system includes: a distance measurement unit that measures a winch-to-winch distance between first and second winches based on the wound length of a second wire or the unwound length of a first wire when an object suspended through the first wire from the first winch and suspended through the second wire from the second winch is moved from the first winch to the second winch; and a relative position determination unit that determines the relative position of the second winch with respect to the first winch based on the winch-to-winch distance. The length of the first wire unwound from the first winch and the length of the second wire unwound from the second winch are calculated based on the relative position of the second winch with respect to the first winch and the target position of the object.
