The invention discloses a precise positioning method and device of a crane lifting hook and an aluminum packet lifting ring. The method is as follows: a vertical rangefinder used for measuring a vertical height and a horizontal rangefinder used for measuring a horizontal distance are installed on the crane lifting hook; an operator in a crane firstly moves the center of the crane lifting hook to the same height as the center of the aluminum packet lifting ring vertically, according to the measurement value of the vertical rangefinder and the height value from the center of the aluminum packet lifting ring to the ground; then, the X direction distance W of the center of the aluminum packet lifting ring is measured through a vehicle-mounted rangefinder on a remote control buggy, and the center of the crane lifting hook is moved to L=W along the X direction according to the measurement value L of the horizontal rangefinder; the center of the crane lifting hook is moved along the Y direction to contact the lifting hook with the lifting ring by keeping the state of L=W, so as to finish the precise positioning of the crane lifting hook and the aluminum packet lifting ring. According to the precise positioning method disclosed by the invention, a DSP control unit is used as a control core to finish the quick and precise positioning when an aluminum packet is lifted by the crane. The crane operation can be simplified, the labor intensity of workers is alleviated, the working efficiency is improved and the production cost is reduced.

The invention provides a crane control method and device. The crane control method comprises the steps that a target position is determined, and the positions of a large vehicle mechanism, a small vehicle mechanism and a hook clamp are determined; and after a crane is controlled to operate to a lifting position to lift a steel reel, the crane is controlled to operate to an unloading position to unload the steel reel. The control device comprises a first determining module, a second determining module and a crane control module. The first determining module is used for determining the target position. The second determining module is used for determining the positions of the large vehicle mechanism, the small vehicle mechanism and the hook clamp. The crane control module is used for controlling the steel reel in the lifting position to be lifted to the unloading position. The target position and the position of the hook clamp are determined, thus the longitudinal moving distance of thelarge vehicle mechanism, the transverse moving distance of the small vehicle mechanism and the descending moving distance of the hook clamp are calculated, the crane is controlled to lift the steel reel placed in the lifting position to the unloading position so that the crane can be controlled automatically without the need for manual operation, and the problems that a crane needs to be operatedand observed by people, consequently safety is low, and operation efficiency is low are solved.
