一种改进的分段线性趋势压缩算法及应用

An Improved Piecewise Linear Online Trending Algorithm and Its Application

目前在过程数据压缩方面应用最广泛的是各种分段线性算法,但在处理工业生产线监控数据时,这些算法都存在各自的缺点。本文提出了一种改进的分段线性趋势压缩算法,在保持原算法的优势的同时克服了其不适于处理平稳数据的缺点,大大提高了数据压缩比和压缩速度。

Many algorithm of piecewise linear has been used in process data compression. But all of this have different disadvantage in processing the data of product line monitor system. An improved Piecewise Linear Online Trending algorithm has was developed in this work. With kept the advantage of original algorithm, it has solved the problem in processing steady data and improved the compression ratio and speed.
