以太网、CAN与LON3种总线控制网络静态网络性能分析

Static Network QoS Analysis on Three Bus Control Networks:Ethernet,CAN and LON

在工业底层现场仪表与自动化装置中,控制网络和现场总线技术的应用已经成为发展趋势。本文通过图表详细分析和对比了3种基于CSMA协议的总线控制网络(以太网、CAN和LON)静态网络性能指标。由三者静态网络性能的分析,进一步归纳和总结了它们在控制领域中的不同应用范围。本分析方法对于其他控制网络同样适用,其结论对于实际工程控制网络设计具有一定的指导意义。

In industrial bottom instruments and automatic control devices,application of control networks and fieldbus technologies has become a trend.The static network QoS of three control networks,Ethernet,CAN and LON,is analyzed and compared through charts and figures.Moreover,the different applications of the three control networks in control field are drawn.The method can also be applied to other control networks and the analysis results have much significance in practice.
