摘要
卫星地球站监控系统是卫星通信地面总体中的子系统,能够自动采集被监控设备的实时状态及故障数据,而卫星系统又是上层通信管理系统的子系统。本文设计了一套基于数据分发服务(DDS)的北向接口,可用于实时、可靠、标准地传输监控系统与上层管理系统之间所需信息,该接口起到两者之间承上启下的作用。通过大量装备试验,有效验证了DDS可以明显提高系统之间传输的实时性、扩展性和耦合度。
Satellite earth station monitoring system is a subsystem of satellite communications ground system. It can automatically collect read-time status and fault data of monitored equipment. Then,satellite system is also a subsystem of upper communication management system. We design a set of DDS-based northbound interface which can be used for real-time,reliable and standard transmission of information between monitoring and upper management system. This interface serves as a link between the two. A large number of equipment experiments validates that DDS can significantly improve the real-time,scalability and coupling of transmission between systems.
