航天测量信息实时质量分析方法

Information Real-time Quality Analysis Method in Aerospace Measurement

针对航天测量信息数据分析依靠事后处理时效性差的问题,提出一种实时数据质量分析方法。根据数据质量分析一般方法和航天测量信息的特点,建立规范性、实时性、准确性和可靠性4个维度的测控信息质量分析模型和质量分析规则,通过按需组合规则、定制分析流程,实现了对航天测量信息的动态实时监视预警、异常数据捕获和故障判断。在测控网中测试结果表明:该方法能够及时发现航天试验中测量信息在采集、传输、处理过程中的问题,并对任务完成情况进行准确评价,对其他面向实时数据流系统的数据清洗也有一定的参考价值。

In view of problem that bad timeliness of post processing of aerospace measurement intbrmation data analysis, put forward the method for real-time data quality analysis. According to feature data quality analysis method and aerospace measurement information, establish measurement and control information quality analysis model and quality analysis rule of standardization, reality, accuracy and reliability. Recognize rule according to requirement and customization analysis process, realize dynamic real-time monitoring pre-alarming, abnormal data capturing and fhilure judgment. The result in test and control net show that the method can find out problems of measurement intbrmation in collecting, transportation and processing in aerospace test. Evaluate the completion of the mission accurately. Furthermore, it has some values for other real-time data stream systems.
