摘要
介绍了Savitzky-golay光滑滤子的滤波原理,分析了使用滑线变阻器对断路器动作进行实时采样所采集的数据以及用一般数据处理方法对数据进行预处理的不足。提出了采用Savitzky-golay滤子滤除数据干扰信号的软件滤波方法。最后给出了实际计算结果并作了分析。
On the basis of introducing the theory of Savitzky-golay digital smooth filter, and analyzing the disadvantage of real-time data that is acquired by periodic sampling from the action vacuum circuit breaker (VCB) with slippery line rheostat, a new method is proposed using Savitzky-golay smooth filter to filter the jam signals in this paper. The results are presented.
