基于Socket的卫星地球站数据管理系统

Design of Data Management System for Satellite Earth Station Based on Socket

本文简要介绍了基于CAPS系统的海洋环境卫星监测系统(CAPS-OC),研究了卫星地球站数据管理系统的实现方法,比较了单接收机和多接收机两种模式下数据管理系统客户端软件和服务器端软件的框架设计,提出了基于Socket技术的多接收机管理系统框架。在Windows环境下采用WinSock控件实现了系统由单接收模式到多接收机工作模式的转变。结果表明,该工作模式结构设计合理,编写的系统软件性能稳定,运行可靠,大大提高了服务器对硬件资源的利用率,降低了卫星地球站的硬件成本和人力成本,为站点的业务化运行及未来系统的进一步升级提供了技术支持。

A design method of the software framework for Data Management System （DMS） in earth station for low-rate Marine Environmental Monitoring System based CAPS was introduced and studied. The single and multi-data receiving modes of DMS were represented respectively. In comparison with the software frameworks design of client and server for DMS with the two modes, a multireceiving framework based socket technique for DMS was proposed finally. A multi-data receiving framework mode evolved from a single-receiving mode by using WinSock module in Windows environment were more efficient and reasonable, furthermore, having higher software reliability in system. The software implement designed for the earth station improved the effective utilization of server hardware, and reduced the cost in using earth ground hardware and human resource, as well as providing well technique support for the station operation and the system updating in future.
