摘　　要：智慧矿井平台能够提高采矿产量,其中通信、定位和传感系统能够保证矿工和矿物的安全。传统射频信号带宽不足、衰减严重和通信设备笨重等因素限制了其在矿井中的应用,第五代移动通信技术可应用在矿井下,但依然存在电磁干扰问题。无线光信号具有免疫电磁干扰和带宽宽的优势,而且无线光通信、定位和传感可借助矿井下光源设施,减少了通信设备成本和损耗。文章分别从无线光传播特性、通信方案、定位和传感几个方面介绍了矿井无线光研究现状,最后对矿井无线光通信小区布设、光源设计、中继方案和矿车防碰撞的发展进行了展望。Intelligent mine platform is able to increase mining production,among which communication,positioning and sensing system can guarantee miner and mineral safe.However,the lack of bandwidth of traditional redio frequency signal,serious attenuation and heavy communication equipment limit its application in mine.5G signals can be applied in mines,but electromagnetic interference is still existed.The wireless optical signal has the advantages of immune electromagnetic interference and high bandwidth,and the wireless optical communication,positioning and sensing can rely on the underground light source facilities,which reduce the cost and loss of communication equipment.This paper introduces the research status of mine wireless light from the aspects of wireless light propagation characteristics,wireless light communication scheme,wireless light positioning and wireless light sensing.Finally,we forecast the development of mine wireless light communication district layout,light source design,relay scheme and mine car collision prevention.
