    Safety monitoring method of underground operation in coal mine by integrating pyramid structure and attention mechanism

    • 摘要: 煤矿井下作业安全监控过程中,主要依靠固定传感检测,监测数据传输困难,导致作业异常安全监控预警频率下降,为此提出对融合金字塔结构与注意力机制的煤矿井下作业安全监控方法的设计分析。在煤矿井下建立局部坐标系,部署监控节点,通过坐标系和局部监控节点确定可监控空间,在该空间之内,将局部坐标系转换为全局坐标系,融合金字塔结构,将全局坐标系中节点采集的图像归类,作为可应用条件。利用采集的图像,进行空间特征的提取,明确空间注意力后,以特征为引导,映射关键监控区域,在该区域内计算出全局坐标系中各点位之间的安全监控均方误差。增设动态预警规则,根据监控均方误差的变化,利用规则判定监控情况是否存在异常,输出最终的监控结果。实验结果表明:所提方法得出的作业异常安全监控预警频率均可以达到205 Hz以上,说明对作业实况异常的感知速度较快,优越性较强。

       

      Abstract: In the process of underground operation safety monitoring in coal mine, it mainly relies on fixed sensing detection, and the monitoring data transmission is difficult, which leads to the decrease of abnormal operation safety monitoring and early warning frequency. Therefore, this paper proposes the design and analysis of underground operation safety monitoring method integrating pyramid structure and attention mechanism. The local coordinate system is established in the coal mine and monitoring nodes are deployed. The monitored space is determined through the coordinate system and the local monitoring node. Within this space, the local coordinate system is converted to the global coordinate system, and the image collected by the nodes in the global coordinate system is classified as the applicable conditions. By using the collected images, the spatial features are extracted, the spatial attention is clearly defined, and the key monitoring area is mapped with the guide of the features, and the mean square error of security monitoring between points in the global coordinate system is calculated in this area. Add dynamic warning rule, according to the change of monitoring mean square error, use the rule to determine whether the monitoring situation is abnormal, output the final monitoring result. The experimental results show that the monitoring and warning frequency of operation anomaly safety obtained by the proposed method can all reach more than 205 Hz, which indicates that the proposed method has a fast perception speed and strong superiority in the abnormal perception of operation reality.
