| 摘 要： | 介绍了小波分析的基本概念，小波变换用于信号压缩和消噪的基本理论和算法。分析了电器采集数据的特点。并针对该特点提出了一种基于分解系数最大值的阈值选取方法，确定最佳小波函数的选取，并给出了仿真实例，证明了本方法的实用性。井计算了采用不同小波函数以度不同阈值选取方法时信号的压缩比。比较了压缩和消噪效果的不同。

| Abstract: | The paper introduces the concept of the wavelet analysis,and also the basic theory and method of the application of wavelet analysis in the field of electrical data processing.The characteristic of the electrical data is discussed,a method selecting the limen based on the max analysis coefficient is put forward,and a simulation instance is given to prove the practicality of the method.The comparison of compression ratio between different plans is done;these plans are concerned with different method selecting the limen and different wavelet functions. |

| Keywords: | discrete wavelet transform selection of the limen compression ratio |
