Development of the Communications-Based Train Control System for Modcow Metro

摘要

The ARS-R, communications-based train control (CBTC) system under development, is the key element of the integrated automatic train control network in the Moscow Metro. It accomplishes vital functions providing safety of traffic movement. The ARS-R system perfors automatic train speed regulation utilizing a radio channel for train-to-wayside data communication. The ARS-R system performs automatic tain speed regulation utilizing a radio channel for train-to-wayside data communications. The integrate network is combined to perform the safety-critical Automatic Train Protection 9ATP), as well as Automatic Train Supervision (ATS) and Automatic Train Operation (ATO) functions. Each function is provided by the additional fail-safe hardware which is installed along with the appropriate software utilizing mutual data communications architecture. This paperdescribes the configuration, design principles, operational algorithms and the number of technical characteristics of the ARS-R including the raio communications subsystem.
