摘　　要：快速正确的遥测数据处理是航天发射试验结果鉴定评估的前提。针对传统遥测处理软件因型号需求变化造成的维护困难问题,设计并实现了一套智能化多站遥测数据处理系统。该系统将数据处理过程分为预处理层、协议解析层和参数还原层,在预处理层,提出一种帧计数约束的多站遥测数据拼接方法;在协议解析层,提出嵌套协议树和标准化1553B总线消息的解析方法,解决了传统结构化数据处理难题;在参数还原层,提出一种基于公式流处理的参数物理量还原方法。系统为多型号遥测参数处理提供了一个统一的架构,解决了遥测数据处理软件任务准备时间长和程序维护困难等难题。Processing telemetry data fast and correctly is the premise of launch experiment result evaluation.Aiming at the difficulty of telemetry data processing software maintenance,an intelligent multi-station telemetry data processing system is designed and implemented in this paper,which includes three key layers of pretreatment layer,protocol parsing layer and parameter recovering layer.A data splicing method is presented to combine the multi-station telemetry data in the pretreatment layer.Then in the protocol parsing layer the parsing methods of nested protocol tree and standard1553B bus message are provided to process the structured data.Lastly the physical parameter recovering method based on formula-tube is proposed in the parameter recovering layer.The system provides a unified construction to process telemetry data in multiple tasks,which perfectly solves the difficult problem of telemetry data processing software maintenance.
