Research on the safety controlling and emergency system for satellite launching

With the aim at building a intelligent emergency system for space launching, the paper discusses the system structure, the emergency decision-making, the rocket status computation and judgment, the knowledge representation model of goal-rule base-character status entities and the master-slave inferring mechanism for normal and abnormal rocket flying status. Especially the paper gives out the trajectory data processing model for the rocket status judgment. And with the support of the knowledge representation model of goal-rule base-character status entities and the master-slave inferring mechanism, the paper introduces a methods of building real-time emergency system.
