| 摘 要： | 工业控制中需要记录大量的历史数据，因其数据量庞大，需要的存储空间也及其庞大，同时网络传输过程的实现比较困难，针对这一情况，提出了一种基于整数小波变换和多级树集合分割编码压缩新算法，并在DSP平台上实现，给出仿真结果，结果表明此算法可方便地控制数据压缩比和重构误差，并且具有压缩速度快、熏构误差小和压缩比高的特点。

| Abstract: | A novel compression algorithm for the history data recording of industry control system is proposed.This algorithm is based on integer wavelet transform and set partitioning in hierarchical trees for controlling data's compression ratio and reconstruction difference expediently.The simulation results showed that the features of algorithm were fast compression rate,high compression ratio and small reconstruction difference when the method was applied to the compression decompression process of temperature signals. |
