摘　　要：智能移动作业平台是实施“精细农业”的基础。自动导航控制技术是智能移动作业平台的重要技术之一。为了开展农田智能移动作业平台及其导航控制技术研究,将计算机技术、传感器技术、GPS技术和数据通讯技术等集成与融合,研制了一种以蓄电池为电源,电动机为动力的农用智能移动作业平台模型。在平台模型的基础上,开发了基于GPS和电子罗盘的导航控制系统。详细论述了导航控制系统的工作原理、控制方法。试验结果表明,该平台模型能按预定的路线行走,直线行走偏差在1m以内,弯道行走偏差在2m以内。通过对导航误差进行分析,提出了进一步改进的方法。该研究为“精细农业”作业平台研究进行了有益的尝试。Intelligent flexible farming platform is the basis of precision farming. Automatic guidance was one of the important technologies for intelligent farm machine. For studying the intelligent farm machine and its automatic guidance control, a field intelligent chassis for precision farming was developed. Two electric motors were used to drive the chassis by means of speed reducing mechanism and control unit. The navigation control system was developed based on the intelligent chassis using GPS and digital compass. The chassis could move along the fixed line, turn around and stop automatically. Test results indicated that the navigation error was less than 2 m when the intelligent chassis ran following the predefined route. The improved method was put forward based on the analysis of the test results. The chassis could be used as a working platform for precision fertilizing, spraying and so on.
