摘要
工业企业数字化转型的进程,包括实施智能制造和工业4.0的进程都迫切需要解决在工业环境下让所有的联网组件实现工业互联网的部署,现实的解决方案应该是采用以太网一网到顶的联网架构,实现从现场仪表和传感器到控制系统、到云基和预置企业管理系统的联接性。当前,单对以太网技术(SPE)和时间敏感联网(TSN)技术的针对性进展令人鼓舞。SPE运用到工业现场特别是流程工业,还需要先进物理层(APL)的支撑。APL是采用IEEE 802.3cg协议的加固的、二线制、回路供电的以太网物理层,在不久的未来,它将取代现有的现场总线和工业以太网,并带来极大的技术利益和经济利益。
In the process of digital transformation of industrial enterprises,including the implementation of intelligent manufacturing and industry 4.0,there is an urgent need to deal with the deployment of industrial Internet for all networking components in the industrial environment.The practical solution should be the adoption of an Ethernet-to-top networking architecture,to realize the connection of field instruments and sensors to control systems,to cloud based and on-promise enterprise management systems.At present,the progress of single-pair ethernet(SPE)technology and time sensitive network(TSN)technology is encouraging.The application of SPE to the industrial site,especially the process industry,also needs the support of advanced physical layer(APL).APL is a ruggedized,two-wire,loop powered Ethernet physical layer using IEEE 802.3cg protocol.In the near future,it will replace the existing field bus and industrial Ethernet,and bring about great technical and economic benefits.
