摘要
简要介绍了数学形态学滤波的原理,提出一种利用数学形态学滤波器预处理tanδ在线监测数据的方法,它通过移动结构元素有效地检测并平滑tanδ在线监测数据中的突变点,物理意义明确,算法简单易行;同时也指出了应用中需注意的问题,并以实例分析验证了方法的有效性。
The principle of mathematical morphology is briefly introduced in this paper. Then a novel approach based on mathematical filter to preprocess on-line monitoring tanS data is presented. With moving structure element, the singular points among the data can be detected and smoothed effectively. The physical meaning of this approach is clear, and it is easy to be realized. Problems of its application in preprocessing tanS data are pointed out too. Finally, analysis results of practical data have verified its effectiveness.
