基于GNSS-RTK水田平地机的设计与试验OA

A paddy field motor grader based on GNSS-RTK is designed in this study.According to the requirements of paddy field leveling operation,the mechanical structure,hydraulic pressure and control system of paddy field grader are designed.The control system is based on GNSS-RTK satellite positioning technology,adopts Cortex M3 series controller and RT-Thread embedded real-time operating system to complete the high-precision detection of the leveling shovel ele-vation,and realizes the automatic adjustment of the leveling shovel height.The field test results show that the design of the grader mechanism is reasonable,the control system runs stably and reliably,and the leveling accuracy meets the re-quirements.The system has a certain reference value for the study of paddy field graders.
