Embodiment Construction
[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0028] The boom control system generally sets a first coordinate system for controlling the movement of the end of the boom, such as image 3 Shown, the first coordinate system x 1 oy 1 Generally, the center of rotation of the boom is taken as the origin O of the coordinate system, the length direction of the concrete pump truck body is the X1 axis, and the direction perpendicular to the length of the concrete pump truck body is the Y1 axis.
[0029] For the remote control of the intelligent control boom, a second coordinate system x for obtaining the angle and orientation of the universal remote control handle is generally set 2 oy 2 ,Such as image 3 As shown, the second coordinate system ...

The invention discloses an arm support control method, which comprises an intelligent control mode. The intelligent control mode comprises the following steps that: step 1, a coordinate calibration hand lever is turned on on a remote controller, a universal remote control hand lever is pulled in the fixed reference direction of engineering machinery, and a first angle signal is obtained; step 2, the coordinate calibration hand lever is turned off on the remote controller, the universal remote control hand lever is pulled to a target moving direction of the tail end of the arm support, and a second angle signal is obtained; and step 3, an arm support controller receives the first angle signal and the second angle signal, and the tail end of the arm support is controlled to move in the target moving direction. The invention also provides the engineering machinery and an arm support control system. Regardless of the operation position of an operator, the pulling direction of the universal remote control hand lever is identical to the target moving direction of the tail end of the arm support; the manufacturing cost is low; and the operation stability is good.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery and boom control system and method. Background technique [0002] The boom of construction machinery, such as the boom of a concrete pump truck, is generally composed of 4-section arms, 5-section arms, and 6-section arms hinged to each other, and the concrete is transported to the target pouring point through the boom. For the control of the boom, there are currently manual control methods. Generally, the manual control method is provided with a corresponding boom segment remote control handle on the remote control. If the boom consists of 4 arms, the remote control is provided with 4 boom segment remote control handles. , one boom section remote control handle controls the movement of one boom section, and the operator uses the remote control to control each boom section separately, so that the whole boom can move from the initial posture to the targ...
