Noise reduction method for underground coal mine monitoring data

The invention relates to a noise reduction method for underground coal mine monitoring data, and belongs to the technical field of monitoring data noise reduction. Comprising the following steps: S1, collecting gas real-time data X0; the gas real-time data comprises a peak value of the gas concentration in a period; s2, judging whether the peak value is in a range of X1 < = X0 < = X2; s3, starting the data noise filtering identification model; judging whether the duration T0 of the peak value in one period is greater than or equal to T1 and less than or equal to T2; s4, judging whether the lifting speed V0 of the peak values of two adjacent periods is greater than or equal to V1 and less than or equal to V2 or not; s5, marking and classifying the invalid data and the valid data and separately storing the invalid data and the valid data; and if the judgment result of any one of the steps S1 to S5 is no, re-executing from S1. According to the scheme, invalid data can be screened and cleaned ...
