摘要
工业控制网络在工业通信及先进制造领域起到关键性作用。回顾了工业控制网络的发展历程,重点分析了工业以太网的实时通信技术,针对通信实时性的强弱性质将目前主流工业以太网进行了分类研究,将其划分为软实时、硬实时以及同步硬实时3类,重点探讨了各自的实时通信机制。同时阐述了正在进入工业控制领域的实时异构网络及无线网络,最后讨论了工业控制网络研究的技术难题,并提出了新的发展方向。
Industrial control network is needed for industrial communication and advanced manufacture. An overview on the evolution process was given, and the real time technology of industrial ethernet was summarized. By analyzing the real time behavior of industrial ethernet, this paper divided it into soft real-time, hard real-time and isochronous real-time classes, and expatiated the real-time research methods of each class in detail. The architecture of real time hetero- geneous networks was described, and the researches of wireless industrial network were proposed. Finally, the prospects and the further research direction were pointed out.
