递推平滑滤波在矿用通风机性能测试中的应用

The application of recursive filtering in mine ventilation performance test

本文对递推平滑滤波的原理及性能进行了分析,得到了滤波器截止频率与采样频率、滤波器队列长度的关系。将递推平滑滤波应用在通风机压力测试中,取得了较好的效果。

The principle and performance of recursive filtering was analyzed in this paper, and the relationship in cut-off frequency, sampling frequency and filter queue length of recursive filtering was obtained. The recursive filtering was applied in the ventilation pressure test and achieved good results.
