An Efficient Route Control Model of the Train-centric Control System

The Train-centric control system integrates the main functions of the whole system into the vehicle, so the train can control the route resources independently. In this system, the route control method which is mainly reflected in the control of the switch is the root to ensure driving safety. This paper focuses on the route control method of the Train-centric system, to find ways to assure the safety of the switch control process and compare track capacity of different control methods. Firstly, we discuss the structural and compositional differences between the Train-centric control system and the traditional Communication Based Train Control (CBTC) system, present the route control process of the new system, as route control method matters the security of the whole system, one of the key problem in this process is the logic to add resource lock to switches, we propose a model to calculate safe distance, and propose two route control approaches, using Simulink/Stateflow hybrid modeling approach to model for both of them, get the visual curve, then build math model to measure and compare the efficiency of the models.
