Problems solved by technology

[0002] At present, the control methods of domestic combine harvesters are all based on the detection and control of the feed amount. This method has some defects, because the load of the threshing drum and the threshing effect are not only related to the feed amount, but also related to the nature and state of the crop.

Abstract

The invention discloses a fuzzy control system for an intelligent combine harvester and belongs to the technical field of automatic control. The fuzzy control system is characterized by comprising an ARM controller (1), a serial interface module (2), a display module (3), an interrupt module (4), a fuzzy controller (5), a signal conversion module (6), an alarm module (7), a JTAG (8), an emulator (9), a personal computer (10), an LCD (11), a pulse signal (12), a Hall sensor (13), a buzzer (14), a driving module (15), a stepping motor (16), a hydraulic stepless transmission (17) and a walking mechanism (18). Compared with the prior art, the fuzzy control system has the advantages of being simple in structure, convenient to mount and debug, high in system reliability, high in measurement accuracy, low in power consumption, easy in popularization and promotion and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery control, more specifically, it belongs to a fuzzy control system of an intelligent combine harvester. Background technique [0002] At present, the control methods of domestic combine harvesters are all based on the detection and control of the feed amount. This method has some defects, because the load of the threshing drum and the threshing effect are not only related to the feed amount, but also related to the nature and state of the crop. . The control method proposed by the invention is based on the detection and control of the rotating speed of the drum. On the one hand, the drum speed is easy to detect; on the other hand, there is a great correlation between the threshing effect and the drum speed. The control system automatically adjusts the speed of the harvester, and then changes the rotation speed of the drum, which strengthens the relationship between the threshing eff...
