| Abstract: | According to the characteristics of the data of power system, the article gives a new scheme to compress the data of power. The article suggests to use Dynamic Huffman coding to compress preproeessed the real-time data of power system. Comparing the test results, it gives a simulation map about this design. Finally, the article gives a power long-range data communications design based on the CPLD and DSP. Being easy and feasible, this scheme is suitable for the power system. And this scheme makes preparation for the transplantation of the compression algorithm mentioned in this article. |
