巷道风速监测点由于人、车经过等因素造成气流波动,导致风速传感器监测值存在“噪声”数据,这种问题无法从现阶段传感器测量技术的本身上解决,使得巷道风速值虽然被实时监测却不能被很好的采信和应用的问题。依据巷道风速变化的特征和拉依达准则本身的特点,提出了应用改进的拉依达准则对实时测量的风速值是否异常进行判定的方法。依托某工作面连续500次巡检风速数据对方法进行了实例验证。结果表明,虽然这种处理方法对巷道风速确实发生变化的状况响应会有延迟,但是对由于风速监测点气流波动所导致的干扰数据能够很好的进行剔除,数据实时处理效果较好。
Roadway wind speed monitoring point due to people and vehicles through the air flow caused by fluctuations, resulting in the wind speed sensor monitoring the existence of “noise ” data, this problem can not be resolved from the current sensor measurement technology itself, making the alleyway wind speed value was real-time Monitoring can not be very good credit and application problems. According to the characteristics of the change of the wind speed and the characteristics of the Raida criterion itself, a method of judging whether the wind speed value is abnormal by using the improved Raida criterion is proposed. Relying on a face continuous 500 times the wind speed data inspection methods to verify the examples. The results show that although the response of this treatment method to the change of roadway wind speed may be delayed, the interference data due to the fluctuation of wind speed monitoring point can be removed well, and the real-time data processing effect is better.
