基于嵌入式的农机GPS辅助导航系统串口通信的实现

Realization of Agricultural Machinery GPS-assisted Navigation System Serial Communication Based on Embedded

介绍了在Visual Studio 2008环境下运用VB.NET的Serialport控件实现GPS接收机和嵌入式系统之间的串口通信,研究了主程序通过串口读取GPS数据后,在对GPS数据信号解码后获得当前位置的经纬度等信息,进而实现导航功能。经过实测,该农机GPS辅助导航系统串口通信程序运行稳定,效果良好。

The use of SerialPort control of VB.NET to realize serial communication between GPS receiver and embedded under Visual Studio 2008 environment was introduced,the main program read by the GPS data from the serial port was studied,the decoded GPS data of the current position,latitude and longitude and other information of current position were obtained to realize the navigation.After be measured,the agricultural machinery GPS-assisted navigation system with serial communication programs run stable,and the effect was better.
