煤矿井下有线宽带信息传输研究

Research of wired broadband information transmission of coal mine underground

  • 摘要: 指出要实现煤矿井下固定岗位无人值守、综采和综放等采煤工作面少人作业,应装备具有地面远程控制功能的煤矿监控系统、监视系统、矿用调度通信系统和矿井移动通信系统等;提出矿井信息传输系统应满足传输带宽宽、有线与无线相结合、抗故障能力强、传输距离远、可靠性高、标准化、安全性好等要求;在分析星型、环型、树型和总线型等煤矿井下有线传输网络结构优缺点的基础上,提出了双巷双缆、单巷双缆、单缆双树冗余结构,认为理想的煤矿井下有线传输网络应采用双巷双缆或单巷双缆双树冗余结构;提出煤矿井下有线宽带传输应采用基于无源光网络的矿用以太网或基于有源光网络的矿用以太网的观点,并提出了这两种矿用以太网的主要性能与技术指标要求。

     

    Abstract: The paper pointed out that realization of unattended operation of fixed workplace of coal mine underground and limited worker operation of fully mechanized mining face and fully mechanized caving face needs to establish control system of coal mine with remote control function, video monitoring system, mine-used scheduling and communication system, mobile communication system, etc. It proposed that information transmission system of mine should meet requirements of wide transmission bandwidth, wired transmission mode combined with wireless mode, strong anti-fault ability, long transmission distance, high reliability, standardization, perfect safety performance, etc. It proposed double-tree redundancy structures of double cables in two tunnels separately, double cables in a tunnel and single cable based on analying advantages and disadvantages of structures of wired transmission networks of coal mine underground including star, ring, tree and bus mode, and considered ideal wired transmission network of coal mine underground should be the double-tree redundancy structure of double cables in two tunnels separately and double cables in a tunnel. It also put forward a view that wired broadband information transmission of coal mine underground should use mine-used Ethernet based on passive optical network or active optical network, and proposed main performances and technique requirements of the two Ethernets.
