摘　　要：以ARM与uC linux嵌入式系统为软硬件平台,对河道上浮标的GPS定位数据的接收和处理作了详细的论述。本系统以三星公司的s3 c44b0x微控制器为核心,GPS模块采用诺瓦泰(NOVATEL)公司生产的OEM板卡superstarⅡ,两者通过串口通讯。用C语言编写的应用程序(运行于uC linux操作系统上)接收从GPS串口发送的浮标定位信息,经过处理,可利用uC linux对TCP/IP的支持,通过无线GPRS网络发送到远端监控中心,重点实现了浮标定位信息的获取。By using ARM and uClinux embedded system as the platform of hardware and software,the receiving and processing of positioning data from the river buoy are described in detail. Taken s3c44b0x processor as the core, the NOVATEL GPS superstar Ⅱ board is adopted in the system. The communication is realized through the serial ports. The buoy position information from GPS is received and processed by the application program with C language running on the uClinux operating system. The data received from GPS can be transmitted to the remote supervisory center through the wireless GPRS network by using the stack of TCP/IP on uClinux. The buoy position information is then obtained.
