列车网络控制系统研究

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.

Design of Train Control and Monitoring System for Line 13 Sao Paulo, Brazil

Subway has become an important part of urban traffic. How to ensure the real-time monitoring of the running status of subway trains in the process of operation depends on the train control and monitoring system. This paper introduces the system structure and hardware configuration of the train network control system of Sao Paulo Line 13 in Brazil. The key control functions of train-level control, traction system, pantograph system, window system, auxiliary system, braking system, air conditioning system, pyrotechnic system, flange lubrication system and other subsystems are described. The fault diagnosis function and PTU function of the system are also introduced. The design of the train control and monitoring system of Sao Paulo Line 13 in Brazil meets the expectation, the performance of the system hardware fully meets the functional requirements, and the reliability and stability of the system software meet the requirements of the train operation. However, for the trains running on the main line, the safety and reliability of the train network control system still need to be verified by the actual operation.
