Work Performance of Railway Station Plan Terminal Over CTC System

摘要

Traffic Dispatching and Command System works as the train dispatching center to make the operational decision on almost every train. The new generation dispatching system called Centralized Train Control (CTC) System works as the train dispatching command system of the China's high-speed rail. The center dispatcher terminal of CTC is the only plan decider to make the final decision on each plan and send them to the stations in its section. In order to make the plan more flexible, this paper put forward a new terminal Station Plan Terminal (SPT) embedded in the existing CTC system to server as the final plan decider. SPT is the terminal used by station dispatcher to receive phase plan from the center and modulate them according to the station situation. After introduction of the new system, we did some simulation and analysis on the function of SPT working in the integrated CTC system. The methodology in our simulation is using SPT to modulate plans according to the station situation, and sent all the plans including the modulated ones to the autonomous machine. The whole work flow of the simulation traverse all the information flow control and logic of SPT. Through the simulation results, we can get that plans refined by SPT and were sent to the autonomous machine took more accurate on route execution, so that the work flow efficiency of the whole dispatching system can be enhanced to some extent.
