摘要: 目前煤矿井下人员定位系统不能二维精确定位。为满足煤矿事故应急救援和机电运输事故防治对煤矿井下人员二维精确定位的需求,提出了煤矿井下人员二维精确定位方法:在井下巷道中,间隔一定距离安装定位分站,定位分站沿巷道一侧布置,并保证定位卡可与两个邻近分站同时进行通信。任意定位卡的相邻两定位分站采用TWR或SDS-TWR测距方法,分别测得两定位分站与定位卡之间的距离。因两定位分站之间距离在定位分站安装时已知,则根据定位卡与两定位分站之间的距离和两定位分站之间的距离,计算出定位卡距定位分站巷道水平径向距离、定位卡距两定位分站巷道轴向距离,再根据两定位分站位置,计算出定位卡在巷道中二维位置。煤矿井下人员二维精确定位方法具有计算量小,定位速度快、定位精度高、定位分站用量少、定位卡和定位分站成本低等优点。

Abstract: Abstract Proposing underground coal mine two-dimension accurate personnel positioning method: locating substations are installed interval at certain distance in the underground gallery,in underground galleries,locating substations are arranged along one side of the gallery, and ensure that the positioning card can communicate with two neighboring locating substations at the same time.The adjacent two locating substations of any positioning card use TWR or SDS-TWR ranging method to measure the distance between the positioning card and the two locating substations respectively.Since the distance between the two locating substations is known when locating substationsare installed, based on the distance between the positioning card and the two locating substations and the distance between the two locating substations, the gallery horizontal radial distance between the positioning card and the locating substations, andthe galleryaxial distancebetween the positioning card and the locating substations are calculated, then according to the positioncoordinates of the two locating substations, calculate the two-dimensional positioncoordinates of the positioning card in underground galleries.
