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。
In order to solve the problem of command and control failure of the aircraft pilot due to the abnormality of the center machine, this paper studies the solution strategy of the combination of physics and information redundancy. By automatically avoiding the data processing cycle which leads to the paralysis of the software system, it automatically receives the takeoff time of the aircraft, Fault and other technologies, the use of heterogeneous backup methods, the construction of a control system with abnormal center system. When the failure of the central computer system caused by paralysis, the system can restore the data processing functions within a few seconds and complete the follow-up tasks to resist the risks caused by the central computer system anomalies and improve the reliability of the central computer system.
