基于CANopen的列车通信网络研究与应用

Research and Application of Train Communication Network Based on CANopen

首先分析了CANopen的应用现状,接着对其物理层、链路层、应用层分别进行了介绍,最后建立了CANopen的通信模型。利用此模型对城轨列车CANopen的拓扑进行分析并改进,降低了总线负载率,为CANopen的应用提供借鉴。

The application status of CANopen is analyzed firstly.Then the physical layer,link layer and application layer of CANopen is illustrated.Finally,a CANopen communication model is established.The CANopen topology of a metro is analyzed and improved by using this model,which may provide a reference for CANopen applications in future.
