| 摘 要： | 对柑橘实时水分监控与旱情预警系统中的数据参数进行拟合分析,在探讨SDT和LZW 2种压缩算法的基础上,提出一种二次压缩算法:第1次压缩采用基于SDT算法思想的甲均值方法;第2次压缩采用改进的LZW算法实现.对压缩效果进行测试,仿真实验证明,在相同的硬件和软件环境下,该算法能实时、高效地压缩数据.

| Abstract: | Aiming at the data parameters fitting and analysis in Real-time Water Monitoring and Drought Early Warning Systems,and based on the discussion of Swing Door Trengding(SDT) and Lemple-Ziv-Welch(LZW) algorithm,this paper proposes a second compression algorithm.In the first compression,it uses average method based on SDT compression algorithm;in the second compression,it uses the modified LZW algorithm to achieve.Through testing the compression effect,simulation experimental results show that in the same hardw... |
