摘要
该文探讨了将交换式以太网应用于实时控制领域的改进策略。介绍基于与现有以太网技术兼容程度的分类。其中该文的重点在保持兼容性的修改策略中的异构策略,且将异构策略划分为了基于端节点的策略和基于网络节点的策略。对各类策略进行了定性的分析和比较,并针对当前基于网络节点的异构策略的不足提出了一种改进思路。最后总结了基于交换式以太网的实时工业通信今后的研究方向。
Switched Ethernet improvements toward real time for industrial applications are discussed.The investigation follows the classification according to the solutions' degree of compatibility with standard Ethernet.The heterogeneous solutions which belong to modifications that keep compatibility are emphasized in this paper and are categorized into two subclasses:solutions in end nodes and solutions in switches.The qualitative analysis and comparisons of all kinds of solutions are given.In addition,an improvement is proposed by the author considering the shortages of current heterogeneous solutions in switches.Finally the future work and directions about the real--time industrial communication based on switched Ethernet are summarized.
