摘　　要：随着城市轨道交通智能化的发展,对网络冗余提出了更高的要求。IEC 62439-3标准提出了一种高可用性无缝环网结构,保证了单节点故障下数据的零延时恢复。为实现单节点设备接入HSR环及HSR环间信息的交互,研究了一种环网冗余装置,并阐述了该装置的软硬件设计思路和工作原理。With the intelligent development of urban rail transit,higher requirements are put forward for network redundancy.The IEC 62439-3 standard proposes a high-availability seamless ring network structure to ensure zero-delay recovery of data under a single node failure.The IEC 62439-3 proposes a high availability seamless ring network structure,which ensures zero delay recovery of data under single node failure.In order to realize the single-node device access to the HSR ring and the exchange of information between the HSR ring,a ring network redundancy device is studied,and the software and hardware design ideas and working principles of the device are introduced.
