摘要
提炼了PCM体制卫星遥测帧的特征结构,在特征结构的基础上,提出一种PCM体制卫星遥测帧通用的,对测控通道遥测、数传通道遥测均适用的自动分类提取的方法。对该方法进行了三种提取模式的试验,结果表明,该方法可实现对大数据量、多源PCM体制遥测数据帧的一次性高效分类提取。
This paper extracted the feature structure of telemetry frames of satellite using PCM telemetry system. Based on the feature structure,an automatic method of classification and extraction,which is universal for all PCM system-based satellites and suitable for telemetry data no matter from measurement and control channels or form telemetry of payload channels,is proposed. The method was tested in three modes,and the results show that the method can achieve one-time efficient classification and extraction of large data volume and multi-source PCM telemetry data frames.
