摘要
分析目前矿井使用主干网络传输系统的千兆工业以太环网系统和GEPON环网系统,研制了一种适用于大中型矿井的网络交换机(以下简称KJJ188交换机),该交换机具备矿井安全监测监控系统使用的RS-485总线和CAN总线,无需其他转换设备,在一台设备中即可实现一线接入可靠传输,可有效减少故障点,减少投资,简化操作。交换机在煤矿井下投入运行后,取得了良好的效果。
Analyzes the current kilomega industrial Ethernet and GEPON loop net system of main network transmission system at underground mine, researches one network switch （KJJ188 switch） that is suitable for middle or large size mine. The RS-485 bus and CAN bus are both suitable for mine safe monitoring system without any other switch equipment, which can realize the reliable transmission line access in one equipment. It can effectively reduce the faults and investment, and simplifies operation. This switch gains good effect when puts into operation at underground mine.
