摘要
针对煤矿监测监控系统数据接口众多,无法实现数据的统一通信和共享的现状,结合EPON技术的优势,设计了一种基于EPON技术的矿用综合数据接入网关。该网关可实现煤矿井下不同接口数据的综合接入和不同系统之间的数据共享。井下实际测试结果表明,该网关主干网络通信速率达到了750Mbit/s,主干网络传输距离达15km,线路冗余切换时间小于100ms。
On account of many data interfaces of coal mine monitoring and control system and it cannot achieve data unified communication and sharing at present, the paper designed a mine-used integrated data access gateway based on EPON technology combining with advantages of EPON technology. The gateway can realize data integrated access of different interfaces and data resources sharing of different systems. The actual test results show that backbone network communication rate of the gateway is 750 Mbit/s, transmission distance of backbone network is 15 km, and line redundancy switching time is less than 100 ms.
