Information Change

Train Movement Authority(MA) concerns train movement safety. This paper proposed a formal model for Chinese Train Control System-3(CTCS-3) based on train MA. Paper analyzed the rounded CTCS-3, formed MA computation models for various application functions, and finished MA hierarchical and functional computation models based on Colored Petri Nets(CPN). The results of experiment demonstrates that the model proposed in this paper is effective, it can reflect the whole information change and transmission process of CTCS-3 accurately, and can help to design and develop MA of CTCS-3.

The Rich

Chinese train control system is abbreviated as CTCS. And there are five levels in CTCS, and CTCS-3 is used for the high speed railway which includes the long rail lines, the different regions, and the rich variety of scenes. It is very important to describe efficiently the relation of the objects for the design and the modeling of the railway visualization. This paper proposes the multi-resolution modeling of CTCS-3 visualization based on meta-model, and introduces the formal description of this meta-model by XML. The formal description examples have certified that this method can provide the enough grammar rules for the reusability of CTCS-3 visualization model.

Reliability And Availability

The reliability and availability of the onboard high-speed train control system are important to guarantee operational efficiency and railway safety. Failures occurring in the onboard system may result in serious accidents. In the analysis of the effects of failure, it is significant to consider the operation of an onboard system. This article presents a systemic approach to evaluate the reliability and availability for the onboard system based on dynamic Bayesian network, with taking into account dynamic failure behaviors, imperfect coverage factors, and temporal effects in the operational phase. The case studies are presented and compared for onboard systems with different redundant strategies, that is, the triple modular redundancy, hot spare double dual, and cold spare double dual. Dynamic fault trees of the three kinds of onboard system are constructed and mapped into dynamic Bayesian networks. The forward and backward inferences are conducted not only to evaluate the reliability and availability but also to recognize the vulnerabilities of the onboard systems. A sensitivity analysis is carried out for evaluating the effects of failure rates subject to uncertainties. To improve the reliability and availability, the recovery mechanism should be paid more attention. Finally, the proposed approach is validated with the field data from one railway bureau in China and some industrial impacts are provided.
