摘　　要：针对现有矿用千兆环网接入器不能满足煤矿井下信息传输带宽要求的问题,设计了一种矿用隔爆兼本质安全型万兆环网接入器。该环网接入器为多电压等级输入,集成了高可靠性的工业级万兆交换机,并扩展出了本质安全型RS-458和CAN现场总线接口,还有后备电池组及电池组信息检测功能。实际应用结果表明,该环网接入器使用方便,性能良好,运行稳定。For the existing mine Gigabit ring network access device can not meet the requirements of coal mine information transmission bandwidth, the design of the mining flameproof and intrinsically safe type 10 Gigabit network access device. The looped network access device for many grades voltage input, integrated with high reliability industrial grade Gigabit switches, and extended the nature safety RS-458 bus interface, has its own back- up battery pack and battery information detection function. The practical application results show that the looped network access device is easy to use, good performance and stable operation.
