Automatic and manual mode switching device for agricultural machinery, control method thereof, and agricultural machinery

Abstract

The invention relates to an automatic and manual mode switching device for agricultural machinery. The automatic and manual mode switching device for the agricultural machinery comprises a stepper motor, an encoder, a single-chip microcomputer, a transmission mechanism and a manual control component. The stepper motor drives the manual control component to move from a stop gear to a forward gear through the transmission mechanism. The stepper motor and the encoder rotating synchronously with the stepper motor are connected with the single-chip microcomputer separately. The single-chip microcomputer reads a feedback signal of the encoder to determine whether man-made interference occurs to the manual control component, and the single-chip microcomputer controls the stepper motor to start and stop. When the man-made interference occurs, the stepper motor stops running, and the agricultural machinery enters a manual mode and moves forward manually. When the stepper motor runs, the agricultural machinery enters an automatic mode and moves forward automatically. The invention also relates to a control method of the automatic and manual mode switching device for the agricultural machinery, and also relates to the agricultural machinery. According to the invention, the automatic and manual mode switching device for the agricultural machinery, the control method thereof and the agricultural machinery have the advantages of simple structure, convenient installation and convenient switchover between automatic and manual driving modes, and belong to the technical field of agricultural machinery.

Description

technical field [0001] The present invention relates to the field of agricultural machinery, in particular to an automatic and manual mode switching device for agricultural machinery and a control method thereof, and also relates to an agricultural machine equipped with an automatic and manual mode switching device. Background technique [0002] Precision agriculture technology is the frontier of modern agricultural development in the world today, and it is the fundamental way to realize the sustainable development of agriculture in our country.
