摘要
通过对传统商用以太网优缺点的分析,指出了以太网在工业界应用的优势以及在实时控制网络中的致命弱点。在此基础上提出了基于令牌的以太网实时调度方法,来改进传统基于CSMA/CD介质访问控制机制的实时性能。
Ethernet in industrial control networks has been widely used.Based on the analysis of traditional commercial Ethernet,its application advantages in industry and the weakness in real-time control network were listed,and the token-based Ethernet real-time scheduling method was proposed to improve real-time performance of medium access control mechanism based on the traditional CSMA/CD.
