基于WinCE的农机导航监控终端软件系统设计与实验

随着农业机械自动导航技术的发展,农机导航监控终端技术已经成为农业机械自动导航技术的重要组成部分。为了满足农业信息化发展的需求,更好地管理控制农机自动导航系统,实现对农机自动导航系统的实时监控与农机作业的控制,开发了农机自动导航监控终端软件系统,可进行农机车辆的导航状态监控、农机具的操纵控制及系统的故障诊断等。通过对农田工作的特点与导航需求分析,采用VS2005开发环境,C++语言,开发基于Win CE嵌入式操作系统的农机车辆自动导航监控终端软件。软件程序的总体功能模块包括:人机交互界面显示、基于RS232的串口通讯模块、路径规划模块、文件读写模块及系统参数调节模块等,并制定导航监控终端与导航控制器之间的数据通讯协议。将该导航监控终端软件系统装在拖拉机上测试运行,结果表明:导航监控终端软件系统可长时间连续稳定的工作,有效实现了对农机车辆导航系统的操作与监控。

Design of Navigation Monitoring Software Based on WinCE for Agricultural Vehicle

Intelligent navigation monitoring terminal is an important component of automatic navigation technology system for agricultural machinery.In order to meet the needs of agricultural informationization development,and real-time moni-tor and control the agricultural machinery operation, the navigation monitoring software for agricultural vehicle is devel-oped.The navigation state of the agricultural vehicle can be monitored, controlled, and the fault can be diagnosed with the intelligent monitoring terminal.According to the feature of field work, the automatic navigation monitoring terminal software is designed based on WinCE with embedded touching screen technology.The navigation monitoring terminal soft-ware included the following modules : man-machine interaction interface, serial port communication module with RS232, measure control module, path planning module, file read and write module.Besides, data communication proto-col between navigation monitoring terminal and navigation controller is formulated.The actual test result showed that nav-igation monitoring terminal software system could realize the operation and monitoring of the navigation system for agricul-tural vehicle.
