摘要
针对干扰噪声的特点,采用中值滤波、均值滤波和移动平均滤波组合而成的复合数字滤波算法,可以有效滤除风机监测系统稳定工作状态下的各种噪声干扰信号。算法运算效率高,适合在在线系统中实现。
According to disturbed noise, the compound digital filer algorithm is designed on the base of median filter, mean filter and moving average filter. It's effective to filter disturbed signals in fan machinery monitoring system when it works on stabilized condition. The algorithm has high operational efficiency, and it is easy to realize in in-line system.
