摘　　要：针对现有煤矿井下基于电磁波的定位系统存在定位精度不高的问题,提出了基于可见光通信的煤矿井下精确定位方法。该方法应用可见光通信技术,采用LED光源广播自身位置信息,依据移动终端接收光信号的强度,计算出移动终端与特定LED光源点的距离,进行二维和三维的精确定位,定位精度可以达到几厘米。相比电磁波定位手段,该方法有效克服了多径干扰现象,定位效果显著。In view of problem of low accuracy of localization system based on electromagnetic wave in underground coal mine,an accurate localization method based on visible light communication in underground coal mine was proposed.The method uses visible light communication technology and adopts own situation information of LED light source to compute the distance between mobile terminal and specific LED light source according to received light signal intensity of mobile terminal,so as to locate by twodimension positioning and three-dimension positioning.The positioning accuracy is a few centimeters with the method.The method overcomes multipath interference and improves localization quality compared with other localization method of electromagnetic wave.
