现场总线技术在城市轻轨和地铁车辆控制系统中的应用

Application of Fieldbus Technology in Control System of Trams and Metros

从轻轨车和地铁车辆的控制系统网络拓扑的结构上对多种现场总线进行了对比 ,并且介绍了各种现场总线的传输介质、通信速率、介质访问方式、数据交换方式、帧结构、差错控制方式等。

From the view of network topology of control systems in trams and metros, many kinds of fieldbus are compared in this paper. And it also introduces the communication medium, transmission rate, function model of medium access, data exchange mode, data frame construction and error control method of different types of fieldbus.
