摘　　要：为了解决煤矿类软件系统在大规模数据量情况下的数据高效存储和查询问题,提出了一种将旋转门SDT数据压缩算法应用于煤矿类软件系统的方案。介绍了该算法的原理及应用推导,给出了模拟量和开关量压缩数据解压还原方法和特殊情况处理方法。应用结果表明,该算法压缩比高,节省了大量的存储空间,能准确地反映出数据的走势和变化。In order to solve problem of efficient data storage and query under condition ot large amount of data in coal mine software system, a scheme of applying SDT data compression algorithm into coal mine software system was proposed. Principle and application derivation of the algorithm were introduced, and decompression method and treatment method under special circumstances of analog and switching compression data were given. The application result shows that the algorithm has high compression ratio, saves great storage space, and can reflect trend and change of data.
