| 摘 要： | 过程数据的实时压缩和趋势提取可以显著提高过程控制系统的整体性能.传统的SDT数据压缩算法不能很好地适应现今过程控制的要求,无法获得满意的压缩结果.针对SDT算法的弊端,提出了一种改进的SDT数据压缩算法,并进行了两种算法的性能对比.对合成数据仿真计算的分析结果表明,基于ISDT算法的过程数据压缩性能有大幅度的提高,更好地满足了现今过程控制中实时数据处理和趋势分析的要求.

| Abstract: | The real-time compression and trending of process data can improve the performance of process control system greatly.The traditional SDT algorithm isn't adaptable to requirements of modern control system,which contributes to be incapable to obtain satisfactory compression results.Considering to the limitations of SDT algorithm,this paper proposes an improved SDT compression algorithm and compares compression quality between the two algorithms comprehensively.The analyses of the data simulation compression indicates that the performance of data compression based on ISDT algorithm is improved remarkably,and ISDT satisfies well the need of data compression and trending in the modern process control system. |
