摘要
针对小变化量数据的传输提出一种转置矩阵位压缩算法,将变化位和非变化位清晰地分开,并对变化位以位为单位进行压缩。实验结果表明:该算法的对小变化量数据的压缩效果很好,即使使用极为简单的行程编码压缩算法也可以取得极高的压缩率;该算法用于处理类似于工业控制系统状态参数等数据时,可缓解系统的网络负荷压力,提高网络的传输效率。
A bit compression algorithm of transposing matrix for slow varying data is presented in this paper. The algorithm separates the changed bits and unchanged bits clearly and the changed bits are compressed on bit level. The experiment result shows that the compression ratio of the algorithm is very high even if the simplest run-length coding is used. The algorithm can reduce web load and improve transmission efficiency in processing data similar to the status parameters of industrial control system.
