列车网络控制系统研究

Research on Train Network Control System

随着世界各国经济的发展,城市规模和人口规模的扩大,城市交通变得更加拥堵,许多发达国家在多年前就着手研究如何使用轨道交通解决城市的拥堵问题,地铁已成为当今城市交通的重要组成部分,地铁列车在运营过程中如何保证其运行状态能够实时受到监控,靠的就是列车网络系统;文章介绍了海外某项目的网络系统结构、硬件配置;阐述了列车级控制、牵引系统、车窗系统、辅助系统、制动系统、空调系统、烟火系统等子系统的关键控制功能,并对系统的故障诊断功能、PTU功能进行了介绍;本项目网络系统的设计符合预期,系统硬件的性能完全满足功能需求,系统软件的可靠性、稳定性达到了列车运行要求。

With the development of world economy,the expansion of city size and population,urban traffic is becoming more congestion,many developed countries in many years ago you set out to research how to use the rail transit solve the problem of congestion of the city,the subway has become an important part of today's urban traffic,subway trains in operation in the process of how to ensure its running state can be real-time monitored,It depends on the train network.This paper introduces the network system structure and hardware configuration of an overseas project.The key control functions of train level control system,traction system,window system,auxiliary system,braking system,air conditioning system and pyrotechnic system are described,and the fault diagnosis function and PTU function of the system are introduced.The design of the network system of this project meets the expectation,the performance of the hardware of the system fully meets the functional requirements,and the reliability and stability of the system software meet the requirements of train operation.
