- Abstract
Information modeling of spacecraft failure diagnosis system is a new challenge, because such systems contain many kinds of different entities, such as spacecraft entity, ground measure and control center entity, spacecraft user entity, spacecraft manufacturer entity and ground diagnosis center entity etc, and the framework and state of these entities are often dynamic. To say essentially, a lot of existing relevant modeling methods lean to the spacecraft entity, or lean to the ground diagnosis center entity, and are lack of capabilities to express thought of failure diagnosis, failure prediction and failure elimination based on integrated space-ground conception, and are lack of thought of system dynamics and aspect-orientation. We present in this paper a methodology for Information modeling of spacecraft failure diagnosis system based on integrated space-ground conception. The methodology is developed from several existing model notions such as information modeling, object-orientation, aspect-orientation, system dynamics, etc. At the same time, to spacecraft failure diagnosis system, integrated space-ground conception is put forward. Finally, an example is shown on how the methodology is applied in the paper.
