Abstract

The invention provides a crane control method and system and a crane, and the crane control method comprises the following steps: acquiring hoisting tension and hoisting displacement of the crane, acquiring image data of a hoisting device of the crane, further acquiring an offset direction and an offset amplitude of the hoisting device, and judging whether the crane has inclined pulling action and hoisting action or not; and controlling a telescopic mechanism, a jib lubbing mechanism, a swing mechanism, the hoisting mechanism and the like of the crane when necessary to reduce and eliminate the damage to the crane caused by hoisting operation in a cable-stayed state and avoid the possible safety accidents of the crane in the cable-stayed state, so that the service life of the crane is prolonged, and the safety of the crane is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical control, in particular to a crane control method, a system and a crane. Background technique [0002] Crane is a kind of hoisting and transporting machinery, including lifting device, used for hoisting, hoisting and other operations. [0003] When the crane is performing lifting operations, its lifting device should be in a vertical state. For example, for a crane whose lifting device is a wire rope and a hook, its wire rope should be in a state perpendicular to the horizontal plane during lifting operations. When the crane cannot make its hoisting device in a vertical state due to the limitation of the current position, the crane should be moved to a suitable position before starting the hoisting operation, so that the hoisting device of the crane is in a vertical state when the crane is performing hoisting operations. [0004] In actual operation, when the hoisting device of the crane cannot...
