摘　　要：针对目前农机作业过程中土地利用率低、农机使用效率不高、驾驶员劳动强度过高、机械化损失严重等问题,设计了一种基于Linux和STM8的农机自动导航辅助驾驶系统。系统通过双天线定位定向模块、数据采集模块、控制模块、电机驱动模块、图形化操作界面对农机进行自动控制,从而解放劳动力、提高土地利用率。试验结果表明,本系统在农机作业时能够提供高精度导航,实现自动驾驶,将作业横向误差和交接行误差控制在±2.5 cm左右,有效提高了土地资源利用率、减少了机械化损失。Aiming at the problems of low land utilization rate,low efficiency of agricultural machinery,high labor intensity of drivers and serious mechanization loss in the process of agricultural machinery operation at present,an agricultural machinery automatic navigation assistant driving system based on Linux+STM8 is designed.The system automatically controls the agricultural machinery through the dual antenna positioning and orientation module,data acquisition module,control module,motor drive module and graphical operation interface,so as to liberate the labor force and improve the land utilization rate.The experiment results show that the system can provide high-precision navigation during agricultural machinery operation,realize automatic driving,control the operation error to about±2.5 cm,improve the land utilization rate,and reduce the loss of mechanization.
