Crane hoisting control method and system

Abstract

The invention relates to the technical field of crane automatic control and discloses a crane hoisting control method and system. The crane hoisting control method comprises the steps that initial state information of a crane and the lifting hook target position corresponding to first hoisting operation are obtained, wherein the initial state information comprises the initial rotary angle, the change amplitude and the lifting hook initial position of the crane with respect to first hoisting operation; a hoisting path is determined according to the initial state information and the lifting hooktarget position, wherein the hoisting path comprises the to-be-executed initial rotary angle, the to-be-executed change amplitude and the to-be-executed lifting hook height of the crane; and the crane is controlled to execute first hoisting operation according to the hoisting path and complete first hoisting operation when a lifting hook of the crane arrives at the lifting hook target position. Accordingly, it is guaranteed that hoisting operation can be conducted safely, reliably and automatically, the manual operation intensity can be lowered, and manual misoperation can be reduced.

Description

technical field [0001] The invention relates to the technical field of crane automatic control, in particular to a crane hoisting control method and system. Background technique [0002] The hoisting operation control of the crane is the core content of the crane control system. During the hoisting operation, it is necessary to carry out real-time coordinated control of hoisting, luffing, and slewing. It continuously adjusts the slewing angle, luffing range, and hook height To achieve the target positioning of the suspended load. [0003] The existing control system mainly relies on the operator to manually cooperate with the hoisting, luffing, and slewing operations during the hoisting operation of the crane. Firstly, the crane hook is controlled to be positioned to the initial position of the suspended load, and then the target positioning of the suspended load is realized by continuously adjusting the slewing angle, luffing range, and hook height. During the entire hois...

AI Technical Summary

Problems solved by technology

This manual operation method has at least the following technical defects: first, the existing control method is complicated to operate, and requires very high requirements for operators who have rich operating experience; second, the degree of automation is not high, which increases the operating Third, the entire operation process relies too much on human subjective judgment, which is prone to misoperation; fourth, the quality of operation varies from person to person, which has a certain impact on the safe use of the crane; fifth, due to the low degree of automation It is also impossible to carry out hoisting operations in dangerous working environments
