摘　　要："张衡一号"卫星搭载的空间电场探测仪,可采集全球范围的电场数据,为空间科学研究及实验提供原位观测数据.该载荷产出的波形和功率谱数据都是以H5格式的文件方式存储,但由于电场观测数据量巨大,文件方式储存导致数据应用效率极低.因此,本文提出了一种基于关系性数据库的数据存储方法,可以显著提高数据访问时间.试验结果表明本文存储方法可应用到张衡一号卫星其他载荷数据,为电磁卫星海量观测数据的高效应用提供了有效的技术支撑.The space electric field detector onboard ZH-1 satellite can collect the electric field data of most part of the earth and provide in-situ observation data for space scientific research and experiment.The waveform and power spectrum data generated by the load are stored in H5 format files,but due to the huge amount of electric field observation data,file storage results in extremely low data application efficiency.Therefore,in this paper,a data storage method based on relational database was proposed to improve the efficiency of data usage and reduce the processing time of mega data.The experimental results show that the Storage method can also be applied to other load observation data of ZH-1 satellite,thus provides an effective technical support for the efficient exploration of mega data collected by electromagnetic satellite.
