摘要
阐述了轨道交通综合监控系统中央级和车站级综合监控工业以太网二、三层组网方案,同时对其性能进行了比较。无论是车站内部链路故障、车站交换机故障、车站交换机上联链路故障,还是车站交换机之间级联线故障,三层组网方案都显示出冗余切换的灵活性、快速性和安全性。
According to the demands of integrated supervisory control system （ISCS） of urban rail transit, the industrial Eth-ernet network scheme with two and three layers on station-level and centre-level ISCS are expounded, and their performances are compared. Whether the links fault or the station switch fault occurs, the network scheme of three layers shows more flexibility, speedy and security of redundancy switching.
