摘　　要：由于煤矿井下环境的特殊性,无线信号易受折射、散射、反射等因素的影响,造成了传统的定位技术得不到有效的发挥。通过分析煤矿井下巷道的无线信号传输模型,结合井下巷道自身的特点,提出了一种改进的信号强度指纹井下目标定位算法,利用均值滤波方法去除受多径效应或遮挡产生的野值点。实验结果表明,该算法能够很好地解决其他指纹定位方法在个别点上定位误差较大的问题,提高了总体的定位精度,获得了煤矿井下目标的理想定位结果。The environment in a coal mine is of specificity,where the factors of refraction,reflection tend to interfere with the transmission of wireless signals.Traditional localization algorithms fail to work effectively in the coal mine.The wireless signal transmission model in coal mine is explored.A novel target-location algorithm of fingerprinting technique is proposed for coal mine underground.The outliers that are caused by multipath effect or shadowing are removed by average filter.The experiment results show that proposed algorithm is effective in making up the deficiency of RSS finger-location algorithm in positioning some reference points and improved location accuracy.
