Automatic control device of agricultural machinery plow and control method

Abstract

The invention provides an automatic control device of an agricultural machinery plow and a control method. The automatic control device of the agricultural machinery plow comprises a signal monitoring module, a programmable controller, a hydraulic dive module and a plow execution module; the programmable controller drives a plow in the plow execution module through the hydraulic drive module to implement deep plowing, steering and obstacle crossing actions and the like; and the signal monitoring module is used to monitor a plow state and a tractor running state and to feed the plow state and the tractor running state to the programmable controller. The automatic control method for the agricultural machinery plow comprises a plow steering automation control and plow obstacle crossing automation control. The problem that the traditional agricultural machinery has a plow using control difficulty is effectively solved, the facts that the agricultural machinery plow automatically completes deep plowing control, steering control and obstacle crossing control are achieved, use is simple, and a requirement for a driver's degree of proficiency and driver's labor intensity are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic agricultural machinery plows, and in particular relates to an automatic control device and control method for agricultural machinery plows. Background technique [0002] The traditional agricultural machinery used for cultivating land includes two parts: a tractor and a plow. The function of the tractor is to provide driving and working power, and to perform necessary control on the plow. [0003] When the agricultural machinery is plowing, it is necessary to control the plow as follows: 1. Control the depth of tillage, that is, generally drive the plow through hydraulic pressure to control the depth of the plow cutting into the soil; 2. Lift the plow when turning, and when the agricultural machine turns , the plow tool needs to be fully lifted, otherwise it will cause deformation or damage to the plow tool; 3. Obstacle-crossing control, that is, when the agricultural machine crosses obstacles s...

AI Technical Summary

Problems solved by technology

The key to obstacle control is to control the timing of lifting and lowering the plow. If the timing is too early or too late, it will have a negative impact on the quality of work.

[0004] Traditional agricultural machinery implements manual control of the plow tools. The above-mentioned control of the plow tools needs to be completed manually by the driver, which requires high proficiency of the driver, resulting in high labor intensity for the driver.
