Abstract
In response to the problem of limited space and complex layout of coal mine downhole,wireless signals encounter a large number of obstacles and reflection surfaces during propagation process,resulting in signal attenuation,and producing multipath effects,which seriously affect the accuracy of distance measurement and positioning.Bidirectional distance measurement and intelligent positioning method for coal mine downhole personnel based on RSSI data and LQI wave filtering is proposed.The RSSI value of the LQI wave filter is obtained,and the joint estimation parameters of LQI bidirectional distance measurement are obtained by combining the distance measurement channel parameters.These parameters are used as inputs to construct downhole distance measurement and positioning model to avoid path loss of signal propagation and positioning errors caused by multipath effects.The positioning probability density at this time is calculated according to the RSSI attenuation value,thus completing the bidirectional distance measurement and intelligent positioning of coal mine downhole personnel.The experimental results show that the horizontal and vertical distance measurement and positioning error of the design method are less than 0.1 m,which can improve the accuracy of coal mine downhole personnel positioning system.关键词
