| Abstract(in English) | Distributed railway interlocking system(DRIS) is a new system where all interlocking devices are intelligent and connected via a ring network. The main differences from current interlocking system are that there is no centralized computer processing interlocking logic and all field devices are at the same logic layer. For such a safety-critical system, the specification design and safety assurance are vital steps. In this paper the design and safety assurance approach with Petri Nets are presented. The top-down and bottom-up approaches are used. The designed system model is validated by constructing the reachability graph of Petri Nets. Further, the net is modified by considering fail-safe principle of DRIS. |
