Abstract

The invention relates to the field of automatic control of cranes, and discloses a crane, a positioning system and a positioning method for the hoisting operation of the crane, and a storage medium. The positioning system comprises a panoramic image acquisition device arranged on an arm support of the crane and configured to acquire a panoramic image in a predetermined operation area; a regional image acquisition device which is arranged on the arm support; a processing device which is configured to determine an initial target position of an operation target according to the first position ofthe operation target in the panoramic image; when it is determined that the arm support of the crane moves to a preset spatial distance range of the initial target position, acquiring a regional imageof the position where the operation target is located through the regional image acquisition device with the focal length adjusted; and determining an accurate target position of the operation targetaccording to the second position of the operation target in the region image. Therefore, the full coverage and accurate positioning of a crane hoisting operation scene can be realized, the operationintensity and proficiency of operators are reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of crane automatic control, in particular to a positioning system, a positioning method, and a storage medium for a crane and its hoisting operation. Background technique [0002] For current cranes, such as wheeled cranes, crawler cranes or jib tower cranes, the control of hoisting operations is the core content of the control system. During the hoisting operation, it is necessary to carry out real-time coordinated control of hoisting, luffing, and slewing. It realizes the target positioning of the hoisted load by continuously adjusting the slewing angle, luffing amplitude, and hook height. The existing control system mainly relies on the operator to manually observe the operation target when performing crane hoisting operations, and manually cooperates with the hoisting, luffing, and slewing operations. Firstly, the crane hook is controlled to be positioned at the initial position of the suspended load, and then th...
