摘要
提出了一种无损压缩的数据存储方法,对测控系统中的历史数据进行高效的管理,在监控的过程量很多的情况下,一般能达到1∶30的压缩比,而且将大大提高数据的检索效率。给出了其具体实现,该方法在类似系统中有着广泛的适用性。
In this paper,a method of data compression storage is proposed.It can manage history data in a measurement and control system efficiently.Even with a large number of data to monitor,a compression ratio up to 1∶30 can be obtained.Moreover,it has the advantage of more effective data retrieval.The details of its implementation are provided here.This method can be used in many other applications.
