| 摘 要： | 为解决远程控制系统中海量数据需要压缩的问题,采用小波压缩的方法对过程控制数据趋势进行分析,以Matlab为仿真工具,选取适当的小波基函数和分解层数及阈值,采用Symlets 8的小波分解可得到较好的压缩比率及较高的信号恢复质量.

| Abstract: | To solve the problem of data compress at the remote control system which has the larger data, the paper introduces the data -compressing method which involves wavelet theory and the trend of analyzed data with the wavelet compress in process control. Based on Matlab as emluator, the wavelet function, the delaminating and the threshold value have been selected. The Symlets8 wavelet has been chosen to achieve a higher compression rate and a better signal recovery. |
