[Abstract]:In order to solve the problem that a large amount of industrial floating-point data can be transmitted on GPRS network,A lossless compression method (IFPC) based on the combination of scientific double floating-point compression algorithm and interval coding is proposed to realize the compression transmission and decompression of industrial floating-point data.First of all, the compression effect of FPC algorithm and general lossless compression algorithm is compared with that of general lossless compression algorithm in floating-point part.Experimental results show that the FPC algorithm has better compression ratio and shorter compression and decompression time than the general lossless compression algorithm.The experimental results of FPC algorithm combined with interval coding for compression and decompression of the whole data domain show that the proposed method is better than the general lossless compression algorithm.The lowest compression ratio can be increased by 7.6, the minimum compression time can be reduced by 49.1, the comprehensive transmission time is reduced by 21.3, and the real time of transmission is improved.
