Embodiment Construction

[0013] The obstacle recognition system detects whether there are obstacles in front of the machine, and sets a safe distance of 3m. When there is an obstacle ahead and the measured distance is less than 3m, the alarm device is activated to remind the driver to take corresponding measures; when there is no obstacle ahead or the measured distance is greater than 3m, the harvester continues to work.

[0014] The crop height recognition system detects the current crop height and its lodging situation, and the hydraulic cylinder position sensor detects the current position signal of the header. When the crop height is low or encounters lodging crops, the height of the control header is lowered; on the contrary, the height of the header is raised.

[0015] The grain moisture content sensor and the feed amount sensor respectively detect the grain moisture content, crop straw moisture content and feed amount signals in real time, and send them to the ECU together with the threshing dr...

Abstract

The invention relates to an electrically-driven intelligent combine-harvester control system, and belongs to the field of agricultural machinery. Different sensors are used for detecting feed quantity signals, grain loss rate signals, grain moisture content signals, crop height signals, barrier existing situation signals, seed lift conveyer rotation speed signals, traveling speed signals, header height signals, threshing drum rotation speed signals and winder position and rotation speed signals of a harvester, measured values are sent to an ECU, after the compared processing is carried out between the measured values and setting values, the ECU sends out control commands, automatic adjustment on the traveling speed, the header height, the threshing drum rotation speed, the winder rotation speed and position and the centrifugal fan rotation speed is respectively carried out, corresponding alarm devices are started, and the harvester works in the best state. The intelligent level is improved, the grain losses are reduced, and the labor strength of a driver is greatly relieved.

Description

technical field [0001] A control system for an electrically driven intelligent combine harvester belongs to the field of agricultural machinery. Background technique [0002] Grain combine harvesters are playing an increasingly important role in agricultural production. However, at present, my country's grain combine harvesters have many transmission parts, complex transmission devices, long transmission routes, and low transmission efficiency. Most of them use belt transmission and chain transmission, which has poor reliability. In addition, the deformation of the frame during the use of the harvester will also cause Failures occur frequently. [0003] The grain combine harvester is complex to operate, the driver is labor-intensive, the working conditions are harsh, and the degree of intelligence is low. [0004] With the rapid development of computer technology, electronic technology, and automatic control technology, it is very necessary to use these advanced technologie...
