Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method and system for automatically adjusting the working posture of the working device of the harvester and the system, which can solve the problem that the whole machine, especially the header, bumps along with the driving road during the working process of the harvester, and realize the control of the harvester. The attitude of the working device is actively controlled in real time to offset the impact of road bumps on the header of the harvester, especially to offset the impact of road bumps on the angle of the header of the harvester

no. 1 example

[0061] This embodiment provides a control method for automatically adjusting the working posture of the working device of the harvester, such as figure 1 As shown, the automatic adjustment control method of the working posture of the harvester working device includes:

[0062] S1, after the harvester starts the harvesting operation, obtain the initial attitude value A0 of the working device of the harvester; and collect the attitude measurement value A of the working device of the harvester in real time after obtaining the initial value A0 of the attitude;

[0063] It should be noted that the storage conditions for the initial attitude value A0 of the working device of the harvester are as follows: the direct or indirect drive cylinder of the working device of the harvester does not move (the controller has no output), the harvester has a driving action, and the preset time is maintained; Specifically, in this embodiment, the preset time is 3 seconds.

Abstract

The invention provides an automatic operating attitude adjustment control method and system for an operating device of a harvester. The method includes: after the harvester starts harvesting, acquiring an attitude initial value of the operating device of the harvester; acquiring an attitude measurement value of the operating device of the harvester in real time after the attitude initial value isobtained; calculating a difference value between the attitude measurement value and the attitude initial value of the operating device of the harvester in real time, and generating a control signal ofthe operating device of the harvester according to the difference value; adjusting an attitude of the operating device of the harvester in real time according to the control signal to keep attitude variation of the operating device of the harvester in a preset range. The attitude of the operating device of the harvester can be adjusted in real time according to harvester driving road surface changes, road bump following control of an angle of the operating device can be kept in a running process of the harvester, and accordingly influences of road bump on the attitude of the operating deviceare neutralized.

Description

technical field [0001] The invention relates to the technical field of harvester control, in particular to a method and system for automatically adjusting the working posture of a harvester working device. Background technique [0002] Harvester is a kind of crop harvesting machine, which is used in rice, wheat, corn, cotton, fodder and other crop harvesting occasions. Its working devices include headers, conveying devices, lifting cylinders and accessories. [0003] When the harvester is harvesting, the angle of the header fluctuates with the harvester due to the undulations of the driving road in the field, which in turn causes the harvesting height to become larger or smaller, which affects the working efficiency of the harvester and may also cause crops to waste. [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 device of the harvester to offset the impact of road bumps on the at...
