摘　　要：火箭遥测数据的实时挑点处理结果是发射中心实时监视火箭飞行状态的重要依据,尤其是时间指令参数的处理结果为判别运载火箭发动机点火、关机、星箭分离等关键事件发生与否提供主要依据。根据某型号运载火箭时间指令参数在遥测帧格式中的波道和码位分配,分析目前箭遥时间指令实时处理方法存在的缺陷,提出"增加判别帧数,充分利用冗余信息",通过分析"时序指令"与"时串指令"间存在的"关联"建立"关联知识库",使用知识库进行辅助判别,实现不错判、不漏判的改进设想。The result of real-time processing for rocket telemetry data is an important information to monitor the rocket's flying state real-timely for the launch center.Especially the processing result of time-injunction parameter offers the main information to differentiate the start-up and stop of the launch vehicle engine,and the breakaway of launch vehicle and satellite.According to the assignment of byte and bit of one launch vehicle's time-injunction parameter in the telemetry data frame format,the disfigurement of real-time processing method of rocket telemetry time-injunction parameter at the present time is analyzed,and an improved method is put forward,which increases the frames to differentiate,uses the redundance information adequately,upbuilds the correlative repository after analyzing the relationship between the time-order injunction and time-bunch injunction,uses the repository to distinguish assistantly,and achieves no fault distinguishing and no missing distinguishing.
