Research on Calibration Method for Tractor Automatic Navigation Control System
Abstract: A lower computer control system of tractor automatic navigation based on double-antennas Beidou satellite is developed, including the controller unit, bipolar output unit, RS232 bus communication unit, a switch reset unit and the power conversion unit. To obtain a continuous voltage output, the calibration method of lower control system using least square method to fit calibration curve has been studied. The lower computer control system receives navigation angel and navigation angel offset instruction provided by the host computer through RS232 bus communication unit. Continuous voltage from -10V to +10V is output through the bipolar output unit to adjust hydraulic valves to control the tractor steering after these are processed by the lower computer.
