Modbus/TCP通信在地铁列车网络显示屏的应用

Application of Modbus/TCP Communication on Human-machine Interface for Train Control and Monitoring System

提出一种基于Modbus/TCP的列车网络显示屏以太网通信的解决方案,详细介绍该方案的实现方法,开展通信冗余性、可靠性的深入研究,并最终应用到某国外地铁列车通信网络项目中。现场运行结果表明,利用该方案实现的显示屏运行稳定,实时性及冗余性均符合要求。

This paper presents a TCMS HMI Ethernet communication solution based on Modbus/TCP,introduces in detail the implementation of this solution,takes in-depth research on the communication redundancy and reliability.This solution had eventually been applied to a metro project of a foreign city.The on-site operation results show that the HMI implemented by this solution operates stably,and both the real-time performance and redundancy meet the requirements.
