摘要
分析了CAN总线的高层协议CANopen及其在城市轨道交通列车通信网络中的应用。以1辆国产化直线电机车辆为对象,设计研制了基于CANopen协议的轨道交通直线电机车辆通信网络,包括CANopen通信网络的构架与硬件选型、通信网络参数设计、网络通信流程,以及车载主控制器与制动单元的通信实现等。通过现场试验运行,验证了该通信网络的适用性和可靠性。
With an analysis of CANopen protocol and its application in urban rail transit communication network, and taking the localized linear motor-driven rail transit vehicle as exam- ple, the hardware frame, communication parameters and communication flow chart of the network system based on CANopen are designed, the realization of communication between vehicle on-board controller and brake system is presented. The developed vehicle network system has verified its applicability and reliability in a test operation.
