摘要:
随着我国高速铁路的迅猛发展,列车控制系统虽能充分保障行车安全,但其可靠性不足,严重制约了运营效率的提升,如何快速、有效地提高其可靠性已成为日益突出的关键问题。文章通过对列控车载信号系统进行可靠性建模和分析,阐述了实施外设冗余方案的必要性,并提出配置级冗余和设备级冗余两种具体方案;根据对车载信号系统各类外设的功能要求、工作原理、通信交互、外部依赖对象等方面的研究,进一步分析了这两种方案的适用性;最后介绍了主机单元对冗余外设的管理策略和对冗余数据的选择策略,以说明本文所提方案的适用性。在实际项目中的成功应用验证了文中所提方案的可行性。
Abstract:
With the rapid development of high-speed railway in China, the train control system has been able to guarantee sufficient safety, but reliability issue could still seriously restricts the improvement of operational efficiency. So how to quickly and effectively improve system reliability has become a key issue. By modeling and analyzing the reliability of the onboard signaling system, the necessity to implement redundancy scheme of external devices was expounded and two redundancy schemes were proposed that one is configuration-level redundancy and the other is device-level redundancy. According to the research on the functional requirements, working principle, communication interaction and external dependent objects of different types of external device in the onboard signaling system, the applicability of the two schemes was analyzed. Finally, the management strategy of the redundant external devices and the selection strategy of the redundant data by the onboard host unit were introduced to illustrate the feasibility of the schemes. Practical results show the validity of the device redundancy scheme.
