摘要
综述PROFIBUS现场总线实时性能研究方法。从PROFIBUS现场总线的网络数据传输技术、介质访问控制技术等方面对网络实时性能指标进行了论述,并分析网络负载对网络系统实时性能的影响,论述和对比应用图论和Petri网技术对网络实时性进行建模研究的方法。建立合理的系统网络结构、采用先进的控制技术以提高网络分布式节点的快速响应性,以及选择合适的网络系统建模与仿真方法,是今后对PROFIBUS网络实时性能研究的主要方向。
This paper mainly summarizes the study method of real - time performance of PROFIBUS, and discusses the network data transmission technology, the media access control technology, etc. The influences of network load on real - time performance are ana- lyzed. The modeling methods of graph theory and Petri net are described and contrasted. The main direction of research includes two aspects : one is to improve quick response of distributed network nodes by setting up a reasonable structure of network and adopting advanced control technology, the other is to select a felicitous method of modeling and simulation for network system.
