In order to solve the problem of large amount of data and low utilization rate of spacecraft vacuum thermal test.A test data query and statistics method based on database is proposed to improve the existing data storage model based on file system.Through the analysis of the experimental data format and the optimization of the existing workflow,the test data inquiry system is divided into four big function modules,such as system management,test management,tactic management and statistic analysis.The test time point information is automatically generated by using the filtering algorithm,and the statistical reports of the single test are generated automatically through the test time point,so as to realize the comprehensive inquiry and statistical function of all the test data.At present,the system has been applied to the spacecraft thermal test mission.After testing,the system functions and performance indicators meet the test requirements,and the system can solve practical problems.%针对航天器真空热试验数据量大、数据利用率不高的特点,提出了一种基于数据库的试验数据查询统计方法方法,以改善现有的以文件系统为主的数据存储模式;通过对试验数据格式的分析和现有工作流程的优化,将试验数据查询系统分为系统管理、试验管理、策略管理和统计分析等4个大的功能模块,利用过滤算法自动生成试验工况点信息,并通过试验工况点自动生成单次试验的统计报告,进而实现对所有试验数据的综合查询统计功能;目前系统已应用于航天器热试验任务中,经过测试,系统功能和性能指标满足试验需求,解决了实际问题.
