矿井互逆双环光纤主干通信网研究

结合下一代矿区通信网分层模型和矿井通信网的总体架构,提出矿井通信网的整体拓扑结构应该是:主干部分沿主要巷道构成光纤自愈环,在地面与矿区通信环网相切,井下其它部分则根据巷道分布特点、信息流量和可靠性等要求,构成分支树型或局部环型,就近连接到主干环的结点上.矿井主干环采用互逆双环拓扑结构,通过空间重利用技术提高带宽利用率,采用插入缓冲技术实现数据的快速转发.

Research on network topology and bidirectional dual-ring trunk of mine communication

The layer model and whole structure of next generation mine network were presented to describe the whole topology of mine network. Its trunk should be self-healing ring tracing along the main roadway, which tangencies with the ring network on the ground. The left branches underground can be constructed following the topology of tree or ring according to the distribution characteristic, flow and reliability in the area. Then they can be connected to the nearest nodes on the trunk ring. The topology of mine network should be bidirectional dual-ring. Spatial Reuse Technology was to improve the utilization of channel, and buffer insertion technology was to fork information faster.
