摘要
针对武器动态测试中的数据参数进行研究,设计了基于TMS320F2812 DSP的数据采集与处理系统。在深入了解信号特征的基础上,结合当今数据压缩发展的前沿技术,设计、改进得到一种可应用于实际情况、能够满足实际需求的LZW和游程混合压缩算法。对数据压缩效果进行了测试,试验证明采用该算法能实时、高效地对AD采集到的数据进行压缩。
The parameters of a weapons test are studied, and a data acquisition and processing system are designed using TMS320F2812 DSP. Based on a full understanding of signal characteristics and the current cutting-edge technology of data compression, a mixed-compression algorithm of LZW and run-length coding is developed. The algorithm can meet the actual needs in an actual situation. The data compression effect is tested. And the result shows that the algorithm can efficiently compress the data from the AD converter in real time.
