摘要
针对卫星在轨管理中实时故障检测与解决较弱的现状,应用专家系统工具Jess构建了实时卫星状态诊断系统。系统可以适应遥测组合模式的复杂约束关系和频繁变化,收集、整理领域知识,实时检测卫星的工作状态,发现并提示卫星状态变化,显示状态诊断过程和结果,提供解决异常问题的参考方案,积累故障处理的经验。文章给出了系统总体结构的设计及关键技术的实现,从而为Jess在航天测控领域其他方面的应用提供了一种思路和方法。系统已成功应用于卫星的在轨管理中。
In order to overcome the weakness of real-time fault detection and resolve for the on-orbit geostationary satellite management,a satellite fault diagnosis system based on jess expert system is designed and realized.The system fits in with the complicated constrain relationships among many telemetry parameters combination and many flexible business rules.By collecting and programming knowledge resource in satellite management,this system can detect satellite states in real-time,find and notify the changes of satellite states,then display the diagnosis process and results,give the reference key to solving problem,at the same time,and accumulate the experience knowledge of solving fault.This paper describes the architecture of the satellite fault diagnosis system and the main techniques of implementation.The research presents a new way and founds for further application of Jess on other aspects in TTC system.It has been successfully used for on-orbit satellite management at present.
