摘要

为了保证高可用性,工业自动化系统如变电站自动化系统往往依赖于IEC 62439无缝冗余协议,如PRP和HSR[1]。然而,这些协议实现的高可用性依赖于网络设备的正确布线。这种网络的错误布线可能发生不可忽视的可能性,特别是在网络扩展或翻新期间。本文提出了一种新的分布式解决方案,利用物联网边缘编排层提供的优势,即在工业自动化系统的设备上动态无缝地部署上下文感知应用程序。通过使用编排层,我们的解决方案部署了系统范围的分布式代理,不仅可以以自动化的方式发现PRP和HSR网络中的错误布线,还可以减少错误布线。

Automatic Mitigation of Wrong Cabling in High Availability Industrial Networks
In order to ensure high availability, industrial automation systems such as substation automation systems often rely on IEC 62439 seamless redundancy protocols like PRP and HSR [1]. However, the high availability achieved by these protocols relies on the correct cabling of the network devices. Wrong cabling of such networks can happen with non-negligible likelihood, especially during network extensions or refurbishments. This paper proposes a new distributed solution that leverages the benefits offered by an IoT edge orchestration layer, namely dynamic and seamless deployment of context-aware applications on devices of an industrial automation system. Using the orchestration layer, our solution deploys system-wide distributed agents to not only discover but also mitigate wrong cabling in PRP and HSR networks in an automated fashion.
