Design and Implementation of TT&C Baseband Equipment Resource Pool

针对传统测控基带紧耦合架构引起的扩展性差、资源冗余和布线复杂等问题,提出了资源池化的测控基带云管理方法。基于构建测控基带资源池的目的,在综合分析业内各类虚拟化技术的基础上,提出了基于I/O融合技术的基带设备虚拟化方案,采用UDP确认传输协议确保端到端信息传输高效可靠,结合应用需求制定了关键指标测试方案。测试结果表明,虚拟化后的基带板卡在模式重构时间、典型数据传输时延和传输性能等方面均有提升,在集约型航天测控地面系统中有广阔的应用前景。

Aiming at the problems of poor scalability,resource redundancy and complex wiring caused by the traditional tight coupling structure of TT&C equipment,a resource pooling management method is proposed.On the basis of comprehensive analysis of I/O device virtualization technology in the industry,the baseband equipment virtualization scheme based on I/O fusion technology is adopted,and the UDP-based confirmation transfer protocol is briefly introduced.The experimental results show that the virtualized baseband card has been improved in reconfiguration time,typical data transmission delay and transmission performance.It has broad application prospects in TT&C ground system.
