| 摘 要： | This paper introduces a design of variable-speed large-capacity telemetry data acquisition scheme. By using a lossless compression algorithm to improve the compression ratio、the plurality of data compression、decompression speed and compression performance of the algorithm complexity, etc. It presented a data compression core algorithm of LZW (Lempel-Ziv-Welch) and simulated the results of its execution speed and compression algorithms through software. Using master chip FPGA it completed the high-precision data acquisition compression and acquiried the systems overall compression test. After a lot ofStests,it showed thatSthe schemeScompleted a six-way real-time acquisition and compression speed varying parameters, the compression ratio is above 1.8:1 and the indicators meet the design requirements.
