抵御中心机系统异常风险的策略研究

为解决因中心机异常可能造成的飞行器试验指挥控制失灵问题,研究物理与信息冗余相结合的解决策略,通过规避导致软件系统瘫痪的数据处理周期,自动接收飞行器起飞时间,人机结合判断系统故障等技术,采用异构备份方法,构建了一个具有异常控制机制的中心机系统。当中心机系统异常导致瘫痪故障时,该系统可在数秒内使数据处理功能恢复正常并完成后续任务,抵御中心机系统异常带来的风险,提高了中心机系统的可靠性。

Study on Strategies against Abnormal Risks of Central Computer Systems

A strategy combining physical and information redundancy is studied to prevent failure of command and control in spacecraft flight experiments because of breakdown of the central computer system.Spacecraft liftoff time is automatically received through avoidance of the data processing cycle resulting in breakdown of the software system.Human-machine combined system fault judgment technology and heterogeneous backup method are used to construct a central computer system with an abnormal fault control mechanism.The system can restore the data processing function within a few seconds and resume a mission in case of a breakdown caused by abnormal system faults.This minimizes the risks brought by the central computer system and increases reliability.
