Intelligent arm support control device, system and method and engineering machine

The invention discloses an intelligent arm support control device, system and method and an engineering machine. An arm support comprises multiple connected arm sections. The intelligent arm support control device comprises a receiver and a controller. The receiver is used for receiving a current dip angle of each arm section and a current coordinate and a target coordinate of the tail end of the arm support. The controller is connected with the receiver and is used for confirming the expected coordinate change quantity of the tail end of the arm support according to the current coordinate and the target coordinate of the tail end of the arm support, changing the sequence and maximum allowable values of the dip angles changed for each time according to the expected coordinate change quantity, calculating the current dip angle of each arm section and preset dip angles, and dip angle change quantity of arm sections required to be adjusted and adjusting corresponding arm sections according to the dip angle change quantity. By adopting the technical scheme and after the target coordinate of the tail end of the arm support is set, the arm support can be automatically unfolded to be in a posture corresponding to the target coordinate, manual intervention is not required, the working amount of a machinist is decreased, the requirements for operating level and experiences of the machinist are reduced, and the working efficiency is improved.
