Research on Formal Modeling Based on CPN for Movement Authority of High-Speed Railway CTCS-3
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.
