| 摘要: |
| 在分析铁路供电SCADA系统中E1环形远动通道的物理构成、逻辑拓扑的基础上，总结了点对点和环形2种通道的优缺点。根据通道和路由器的冗余特性，提出了变电站内通信设备的3种典型配置方案：双环单路由器、双环双路由器、单环单路由器。从设备造价、通信可靠性、实施和维护3个方面对3种方案进行了对比分析，发现单环单路由器方案简单实用，造价低，获得了最广泛的应用。最后实现了单环单路由器方案应用于京沪线的配置。 |

| Abstract: |
| The physical layers and logical topology of E1 ring communication channels are analyzed，and the advantages and disadvantages of peer-to-peer channel and ring channel are summarized. According to the redundancy characteristics of channel and router，three typical configuration schemes of communication devices in a substation are proposed：dual-ring single-router，dual-ring dual-router and single-ring single-router，which are compared in equipment cost，communication reliability，implementation and maintenance. The single-ring single-router scheme is simple，practical，inexpensive and widely used. The single-ring single-router scheme configured for Beijing-Shanghai railroad communication channel is presented. |
