摘　　要：针对煤矿井下煤矿综合监控系统,对不同的本质安全型电源供电设备的RS-485接口连接问题,提出在矿用隔爆兼本质安全型电源中使用隔离型RS-485中继器。看重对不同的RS-485隔离中继器进行比较。经现场应用,具有RS-485隔离中继功能的隔爆兼本质安全型电源运行稳定、可靠。Aiming at the RS-485 interface connection problem of different essential safety power supply equipment in the mining underground comprehensive monitoring system, the use of isolation repeater RS-485 in mine flameproof and intrinsically safe power supply was proposed. Different isolation repeater RS-485 has been compored.Through field application,flameproof and intrinisically sofe power supply with isdation repeater RS-485 run steadily and reliably.
