摘　　要：针对传统矿难救援方法设备昂贵、探距较短、误报率高等问题,提出了一种基于信道状态信息的矿难人员检测方法.首先,提出了基于高斯混合模型前景检测方法,以判断被困人员的活跃程度;其次,根据信道状态信息周期性变化,利用自相关函数捕捉人员呼吸频率,以检测非活跃人员;最后在多种实验参数下对所提方法进行性能评估.结果证明,所提方法具有较高的准确度和鲁棒性,平均准确率可达90%.Aiming at the problems of high cost,short detection distance and high false alarm rate in traditional rescue methods,a new method for personnel detection based on channel state information is proposed.First,the state detection module determines the degree of the activity according to the Gaussian mixed distribution.Second,the breath detection module uses periodicity of the influence of human on channel state information to extract breathing,and to find the breathing frequency of the people who remain inactive.Finally,we evaluated the system in a variety of parameters.The experimental result verifies that the system has high accuracy and robustness,and the average recognition rate can reach 90%.
