摘　　要：针对目前煤矿井下光通信设备受环境干扰严重、必须有电源才能实现光纤分支的问题,探索一种新的煤矿井下全光网络冗余技术方案,实现矿井无源光分支多级串联,解决瓦斯监控系统井下光纤多级无源分支及通信抗干扰问题。从F5G组网原理出发阐述全光网络组冗余保护机制,设计一种光纤全矿井广泛覆盖方案及井下F5G通信设备。实验室和现场测试表明,F5G技术可实现井下无源光多级串接,减小煤矿井下环境干扰,保证安全监控系统正常运行。Aiming at the problems of the serious environmental interference of underground optical communication equipment in coal mines and the need to have power sources in coal mines to achieve fiber optic branching,a new technology solution for all-optical network redundancy in coal mines was explored to achieve multi-level series connection of passive optical branches in mines,which solves the gas monitoring system underground optical fiber multi-level passive branch and the communication anti-interference problem.Starting from the principle of F5 G networking,the all-optical network group redundancy protection mechanism was described,and a fiber-optic full-mine wide coverage scheme and underground F5 G communication equipment were designed.Laboratory and field tests show that F5 G technology can realize the multi-stage serial connection of underground passive light in the coal mine,reduce the interference of the coal mine environment and ensure the normal operation of the safety monitoring system.
