S型双环冗余工业控制以太网

S-Type Dual-Ring Redundancy Industrial Control Ethernet

在分析了现有解决网络中产生环路方法的基础上,提出了一种应用在以太网的基于双环S型的冗余工业控制通信方案.研究表明使用该方案的网络是一种具有较短故障恢复时间的高可靠性冗余网络,可以运用在对可靠性要求较高的行业.

After analyzing the existing means to resolve ring topology in redundancy network, this paper proposes a scheme of S-type redundancy industrial control communication based on the dual-ring topology applied in industrial Ethernet. The results indicate that this is a highly reliable redundancy automation net-work with short grace time and can be applied in industry which requires high reliability.
