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

Abstract

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.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an intelligent control device, system, method and construction machinery for a boom. Background technique [0002] Concrete pump trucks have become widely used engineering machinery in modern building construction. Due to their application characteristics and complexity, they need to be controlled by professional operators. At present, the operator controls the movement of the boom through the remote control. Different buttons are set on the remote control to control different boom sections, and the operator operates the boom through the buttons. The experience and proficiency of the operator is very important when it is necessary to quickly position the end of the boom. When a certain arm section is moving in a certain direction, the operator needs to press the corresponding control button all the time. Although this can make the operator maintain a high degree of attentio...

AI Technical Summary

Problems solved by technology

When a certain arm section is moving in a certain direction, the operator needs to press the corresponding control button all the time. Although this can make the operator maintain a high degree of attention and ensure the safe movement of the boom, it does increase the operator's work. quantity

Moreover, in the construction of pump trucks, many boom postures are often used. Therefore, the operator often does some repetitive work, and the work efficiency is low.
