[0042] This embodiment provides an automatic adjustment control method for the working posture of the excavator working device, such as figure 1 As shown, the automatic adjustment control method for the working posture of the excavator working device includes:

[0043] S1, after the excavator completes the material collection, obtain the initial attitude value A0 of the working device of the excavator; and collect the attitude measurement value A of the working device of the excavator in real time after obtaining the initial value A0 of the attitude;

[0044] It should be noted that the storage conditions for the initial value A0 of the attitude of the excavator working device are: the direct or indirect driving cylinder of the excavator working device does not move (the controller has no output), the excavator has a driving or steering action, and maintains the preset time; specifically, in this embodiment, the preset time is 3 seconds.

Abstract

The present invention provides a control method and system for automatically adjusting the working attitude of the excavator working device. The method includes: after the excavator completes the collection of materials, obtaining the initial value of the attitude of the excavator working device; and after obtaining the initial value of the attitude Collecting the posture measurement value of the working device of the excavator in real time; calculating the difference between the measurement value of the working device of the excavator and the initial value of the posture in real time, and generating a control signal of the working device of the excavator according to the difference; according to the The control signal adjusts the attitude of the working device of the excavator in real time, so that the attitude change of the working device of the excavator remains within a preset range. The present invention can adjust the posture of the working device of the excavator in real time according to the change of the driving road surface of the excavator, so that the excavator can maintain the follow-up control of the angle of the working device to the bumps of the road during the driving process, so as to offset the influence of the bumps of the road on the posture of the working device.

Description

technical field [0001] The invention relates to the technical field of excavator control, in particular to a control method and system for automatically adjusting the working posture of an excavator working device. Background technique [0002] Excavator is a kind of earth-moving machinery, which is used for earthwork excavation, loading, leveling, slope repairing, shoveling and collecting of loose materials, etc. Its working devices include arm frame, stick, bucket, driving cylinder and accessories Wait. [0003] When the excavator is transported with load, due to the bumpy road surface, the bucket bumps along with the whole vehicle, which in turn causes the materials in the bucket to spill, which affects the working efficiency of the excavator and also affects the safety of the excavator working site. Clean and safe to work with. [0004] At present, there is no feasible control scheme in the prior art that can actively and real-time control the attitude of the working d...
