深圳地铁1号线续建工程多功能车辆总线网络系统的可靠性分析

Reliability of Multifunctional Vehicle Bus for Shenzhen Metro Line 1

对于列车网络系统来说,可靠性最为关键。列车网络系统可靠性越高,列车运营越安全,可使调试和维护的成本极大地降低。分析列车网络系统的可靠性,寻找列车网络系统可靠性的提升措施,对列车网络系统的设计和维护具有重要的现实意义。以深圳1号线续建工程为例,从列车多功能车辆总线(MVB)的各个方面分析了列车网络系统的可靠性,提出了列车MVB网络系统的可靠性提升措施。建议在列车控制领域,在满足功能的情况下应尽量地减少硬连线积极地推广和使用车辆网络系统。

Regarding the train network system, reliability is most pivotal. The higher reliability of train network system, the safer train service, the lower debugging and maintenance cost. So it is of important meaning for the design and maintenance of train network system to analyse the reliability and find the upgrade measures of train network system. This article takes the extension project of Shenzhen metro Line 1 as example and analyses train network system reliability from various sides of multifunctional vehicle bus（MVB）network system, puts forward some upgrade measures, then calls on extending and using network in train control field to reduce the hard wire as far as the system function is performed.
