摘要
简单介绍了GPS系统及GPS接收机的通信协议,给出了接收机和计算机之间的电平转换硬件电路,并着重讨论了VC++6.0环境下两者进行通信的2种实现方案:一种是API通信函数法,一种是MSComm控件法。最后给出了GPS用户数据提取的一般方法。这种通信方式和数据提取方法同样适合其他GPS OEM产品。
By analysing the GPS system and the communication protocols, the electric conversion circuit of GPS receiver to computer is introduced, and two realization schemes based on VC ＋＋ are discussed： one is the method of API, the other is MSComrn control. The general way of data separation is given. The com- munication modes and the means of data separation can he also used to other products of GPS OEM.
