A kind of intelligent arm support control, system, method and engineering machinery

The invention discloses a kind of intelligent arm support control, system, method and engineering machinery.Described jib comprises interconnective single oil cylinder joint, and described device comprises: receiver, often saves the current inclination of arm joint, the changing coordinates of arm support tail end and coordinates of targets for receiving; Controller, is connected with receiver, for according to the changing coordinates of arm support tail end and coordinates of targets, determines the changes in coordinates amount of the arm support tail end of expecting; According to the maximum permissible value that the changes in coordinates amount of expection, the current inclination often saving arm joint, default inclination angle change order and each inclination angle change at every turn, calculate the change of pitch angle amount needing controlled arm joint; And according to described change of pitch angle amount adjustment respective arms joint.By technique scheme, setting arm support tail end coordinates of targets after, jib can Automatic-expanding to the attitude corresponding with this coordinates of targets, without the need to manual intervention, reduce the workload of tractor driver, reduce the requirement to tractor driver's operant level and experience, improve work efficiency.
