Engineering machine, method for controlling mechanical arm of engineering machine, apparatus thereof, and system thereof

Abstract

Engineering machinery and a method, an apparatus and a system for controlling a mechanical arm of engineering machinery, used for solving the problem in the prior art that using a remote controller to operate a mechanical arm of the engineering machinery is relatively inconvenient. The method comprises: taking a reference benchmark direction (O1X1) as a starting edge and a remote operation direction (O1A1) as an ending edge, acquiring the size of an angle (ß1) formed in a predetermined rotational positive direction; determining a mechanical arm control direction which forms the size of the angle (ß1) with respect to the reference benchmark direction (O1X1) in the rotational positive direction, and then transmitting a control message to control the mechanical arm according to this direction. Using this method means that the direction of travel of the distributing points of a mechanical arm of the engineering machinery can be kept spatially consistent with the remote operation direction and, in this way, with an operator in any position and having provided any operation direction, the distributing points of the mechanical arm will all move according to the operation direction, thereby realizing direct operation of the mechanical arm, bringing convenience to the operator.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to a construction machine and a method, device and system for controlling a mechanical arm of the construction machine. Background technique [0002] At present, the posture of the mechanical arm of construction machinery such as pump trucks is usually realized by the operator using the remote control. The operation method is shown in figure 1 middle, figure 1 is a schematic diagram of the way of using the remote control to control the robotic arm according to the prior art. [0003] Such as figure 1 As shown, the operator 11 holds the control handle 121 of the remote controller 12 to operate, so that the mechanical arm 131 of the pump truck 13 rotates in the horizontal direction, so that the distribution point 132 moves. Because the control starting direction of the control handle 121 is the positive direction of the Y axis in the figure, that is, when the cont...
