摘要
针对目前多数瓦斯监测预警体系采用单一的传感器设备所存在的瓦斯误报率高、监测精度差、可靠性不足的缺陷,提出了一种新的多类型传感器综合瓦斯监测预警体系。该体系将多类型传感器设备进行相互配合,利用多证据匹配理论,对各个传感器监测数据进行综合判断,最终确定井下精确的瓦斯浓度,具有监测精度高、可靠性好的优点,极大地提升了井下瓦斯监测结果的精确性。
A new multi-type sensor integrated gas monitoring and warning system is proposed for the defects of high gas false alarm rate,poor monitoring accuracy and insufficient reliability in most gas monitoring and warning systems.The system combines the multi-type sensor equipments with each other,and uses the multi-evidence matching theory to judge the monitoring data of each sensor synthetically,finally determines the downhole accurate gas concentration,which has the advantages of high monitoring precision and good reliability,which greatly improves the accuracy of downhole gas monitoring results mechanized mining.
