An agricultural machinery steering wheel motor-driven automatic driving device and method

Abstract

The invention provides an agricultural machine steering wheel motor drive automatic driving device which comprises a guidance controller, a touch display device, a motor control steering wheel and a mechanical limiting switch; the guidance controller is used for receiving differential signals, and sending locating information and corresponding data to the touch display device after treatment; themotor control steering wheel comprises a steering wheel motor and a driving device, wherein the driving device controls the steering wheel motor to rotate relatively, and further drives the wheels torotate; and the mechanical limiting switch is used for detecting whether rotating angles of the wheels are rotated to the largest degree, and sending limiting trigger signal feedback to a steering wheel motor driver. Compared with existing agricultural machine automatic driving device steering system controlling function, a front wheel angle encoder is omitted, front wheels rotating angle positionfeedback is achieved by an external mechanical limiting switch and an built-in encoder (incremental type and absolute type) of an electric control steering wheel motor; and agricultural machine steering control is achieved by controlling steering wheel motor incremental motion.

Problems solved by technology

However, the external angle feedback device used in the automatic driving device increases the production cost of the system. At the same time, during the use of the whole system, the transmission parts of the angle feedback device follow the movement of the front wheels. After frequent movements, problems such as loose screws and loose connecting parts are prone to occur. In turn, the angle data feedback is abnormal. For this reason, the angle feedback device needs to be calibrated regularly after reinstallation

While reducing system reliability, it also increases equipment maintenance costs
