Simulation Study Of CTCS-2Train Control Center For Dedicated Passenger Lines

CTCS-2Train Control Center for Dedicated Passenger Lines is an important part of theCTCS-2Train Control System, and also the core equipment for ground signaling system.CTCS-2Train Control Center for Dedicated Passenger Lines doing logical operations bycapturing the approach information、speed limit information、track occupation information andinterstation adjacency critical information, and output the track circuit code order, section signallight code order and Balise Telegram, finally through the track circuit and active transpondertransport information to the vehicular equipment.The vehicular equipment such as LKJ must be debugged in scene at present, and thenimprove the function after debugging; but it needs to spend large quantity of financial andmaterial resources. Therefore, if we can simulate the function of the train control center by themean of software, vehicle equipment can be debugged in the laboratory. It not only reduces theproduction cost, but also shortens the development cycle.This article mainly focuses on researching the Technical Specification and the interfacialprotocol for CTCS-2Train Control Center for Dedicated Passenger Lines, and realizes thefunction simulation of the train control center by using computer simulation technology. Themain contents of this article include the following:1.Design the simulation system. Introduce the function of each module and the dataexchange between the modules.2.Research the way of recognizing the track circuit state, and put forward the correspondingprotection methods.3.Introduce the section track circuit coding principle, and realize the section track circuitcoding logic function.4.Introduce the station track circuit coding principle, and realize the station track circuitcoding logic function.5.Realize the function to control the logic of signal light by using code sequence.6.Design active Balise Telegram editor software. 7.Test the simulation system function.
