SP2539多串口芯片在海洋浮标控制终端上的应用

Application of SP2539 Multiple Serial Port Based on Ocean Buoy Terminal Controller

针对海洋浮标的海洋环境监测,介绍了一种利用GPS定位和卫星通信技术实时传输海洋环境参数的系统。该系统终端采用SST89C58单片机控制,通过SP2539多串口芯片将数据采集模块中的数据存储并通过发射模块发射,同时可以接收通信中心站下行指令。系统运行结果表明,数据发射成功率100%,接收下行指令成功率100%,通信中心站接收误码率<1e10-6。

According to remote controlling based on ocean buoy, a system using GPS and satellite communication for real-time transferring data was introduced. The terminal of this system was controlled by SST89C58. The received data was stored and launched by emission module through SP2539. At the same time the communication command was received through SP2539 too. The results of running this system indicate that success percent of data emission is 100%, and success of command receiving is 100% and BER of receiving communication station is less le10-6.
