基于VB.NET的GPS接收机串口通信的实现

Achievement of Serial Communication of GPS Receiver Based on VB.NET

首先介绍了串口通信和GPS数据格式,然后通过实例详细讨论了在VB.NET环境下应用MSComm控件实现计算机与GPS接收机之间利用串口传输并提取定位信息的方法。所设计的算法可以应用于基于PC机的车载GPS道路信息更新中。实验表明,系统运行稳定、实时性高、准确、简便。

This paper firstly introduced the serial communication and GPS data format.Then,the method using MSComm component to achieve serial communication and extraction of location information between computer and GPS receiver in VB.NET environment was discussed in detail by example.The designed algorithm can be applied to PCbased in-car GPS road information updating.Experimental results show that the system is stable,high real-time,accurate and convenient.
