Abstract:
The air turbulence caused by factors such as human or vehicles of wind speed monitoring points leads to the noisy data existing in monitoring values of wind speed sensor. As the problem has not been resolved by utilizing the measurement technology of sensor at the present stage, the wind speed values of roadway can not be acquired and used. Based on the change characteristics of wind speed in the roadway and the feature of Pauta criterion, a method on applying the improved Pauta criterion to determine the abnormality of real-time measurement values of wind speed was proposed. The method was verified by loop check for 500 times in a row data of wind speed at working face. The results show that although this method made the response delay on condition that the wind speed from the roadway indeed changed, the interfering data caused by the air turbulence of wind speed monitoring points would be culled well and the method would have a better effect on data process in real time.
