航天器故障诊断软件平台中诊断平台的研究和实现

为解决多种复杂航天器系统的故障诊断问题，探讨建立航天器系统故障诊断的平台技术，分析了航天器邦联诊断系统软件平台的总体结构，深入研究了作为软件平台核心部分的故障诊断平台的要求、结构、功能与系统组成，设计了诊断平台的系统总体结构。应用事件代数的方法，分布式的思想与Ｐｏｗｅｒｂｕｉｄｅｒ技术，作为诊断平台任务管理策略与运算规则。最后，通过对航天器系统故障诊断系统的实际研究，证明该技术是有效的、可行的。

Research on and implementation of diagnosis platform in spacecraft fault diagnosis software platform

Because of the increasing complexity of spacecraft fault diagnosis, it is necessary to explore the platform technique for spacecraft of fault diagnosis software. The general architecture of software platform of fault diagnosis for spacecraft is analyzed. The general software platform consists of network platform, database platform and fault diagnosis platform etc. The architecture and function of the diagnosis platform, which is the kernel part of the software platform, are researched deeply and designed.The event algebra and distributed calculation and Powerbuilder are applied for database structure and distributed task management policies. Finally, the efficient and feasible of these technique are proved in fault diagnosis of spacecraft.
