在早期有人驾驶的宇宙飞船飞行期间,地面遥测系统的主要作用是对飞行控制器的数据进行显示。当有人驾驶的空间飞行变得复杂以后,对飞行控制器能同时监控系统和重新调整系统工作的要求更高了。这样对能减少飞行控制的工作负荷的自动遥测监控系统引起了兴趣。伦登的B.Johson航空中心的飞行操作管理局研究出了五层模型以综合各种监控和分析技术,如:数字滤波、故障检查算法及专家系统。本文介绍了这五层模型,并且说明了它如何用于指导飞行控制的样机制作工作。介绍了一些初始专家系统的结果。本文还介绍了当前正在研制的综合样机,它能提供实时专家系统,帮助在飞行控制中心的飞行控制器来监控航天飞机通讯系统。
During the early manned spacecraft flight, the primary function of the terrestrial telemetry system was to display the flight controller’s data. As manned space flight becomes more complex, there is a greater need for a flight controller to be able to monitor and readjust the system simultaneously. This has drawn interest for an automated telemetry monitoring system that can reduce the workload of flight control. The Flight Operations Authority at B. Johnson Air Center in Lundon has developed a five-layer model to integrate various monitoring and analysis techniques such as digital filtering, fault checking algorithms and expert systems. This article introduces the five-layer model and shows how it can be used to guide flight control prototype production. Introduced the results of some initial expert systems. This article also presents a comprehensive prototype that is currently being developed that provides a real-time expert system to help flight controllers in flight control centers monitor the space shuttle communications system.
