Automated system development and control of operational train schedule during “free zones”

This paper presents the architecture and technological foundations of process control automation of the site during the period of “free zones” to determine the composition, functions and conditions of interaction using the satellite technology. The objective function of the presented system based on the condition ensuring passage of the maximum number of trains was developed. Limits and conditions governing the tolerance range of the design parameters were defined. The authors implemented a system of site simulation, taking into account the principles of the “polygon box” and trains on its space-time model, information on approach of trains with a “polygon box” to “section of the zone” and “stretch of the zone” and allowing to construct a projected operational schedule of trains to approach “the stretch of the zone” and to develop an operational packet traffic schedule.
