全数字仿真统一测控系统故障模块分析与研究

Analysis and Research on Fault Module of Numerical Simulation TT&C System

随着航天事业的快速发展,迅速提高岗位人员的操作维护及应急处置能力显得尤为重要;文中针对统一测控系统工作情况复杂的特点,借助HLA/RTI技术架构的分布式仿真平台,构建统一测控设备的数字仿真模型,提出了将设备显性和隐性故障分开、可扩展性强的测控系统故障告警仿真方法;通过上变频器故障仿真分析,结果表明该方法不受故障触发机制、触发时间的影响,可实时、正确给出告警信息,使仿真系统有良好的培训效果。

With the fast development of spaceflight enterprise, it becomes more and more important to improve quickly the ability of op- erating maintenance and emergency disposition for operating crew. According to the complex working instance, a numerical simulation model of TT^C system was established. At the same time, a fault warning architecture is proposed which is flexible and easy extensible, based on HLA/RTI distributed platform. The method proposed to separate the recessive and apparent fault. On the basis of the up transducer simula- tion, application result shows that the method not only make a breakthrough for the limit of burst mode and trigger time but also give real-- time, accurately alarming message and bring favorable training effect.
