摘要
文章介绍了多路遥测数据采集系统在数据存储过程中的特点,根据预测差值大小将遥测数据分为缓变参数和速变参数部分,有针对性地采用LZW算法和Huffman算法混合编码的设计方法,并从理论上阐述了该算法的优点及较优的压缩性能。
This article introduced the characteristic of multichannel telemetry data acquiring system in the process of data storaging,the telemetry data is divided into the slow variable element and the fast variable element parts according to the forecast differential value size,and thus the LZW algorithm and the Huffman algorithm mixed coding method is adopted.Finally,the advantages and the higher performance of this algorithm are described in theory.
