Design And Implementation Of CTC Simulation System Based On CTCS-3 Train Control

With the rapid popularization of high-speed railway in China,the CTC system,as an important part of the CTCS-3 train control system,has been rapidly developed and applied.For CTC system operators and students in related majors,not only need to master the relevant theoretical knowledge of CTC,but also be familiar with the overall structure and operating process of CTC system,in order to better understand and give play to the huge commanding advantages of CTC system in transportation organization operation.Aiming at the dispatch command role and teaching simulation requirements of CTC in CTCS-3 train control system,the CTC simulation system are designed and implemented based on the laboratory CTCS-3 train control simulation platform.The CTC simulation system has good practical value.On the one hand,it can intuitively and clearly show the closed-loop control process of train operation,and is conducive to understanding and learning the operation method and control concept of the CTC system.On the other hand,it can improve the overall architecture of the laboratory CTCS-3 train control simulation platform,and can provide certain platform support for theoretical research related to CTC and train operation control.Firstly,learn about the true architecture and core functions of the CTC system by consulting relevant materials and related research results at home and abroad of the CTC system.Based on the functional requirements of the laboratory CTCS-3 train control simulation platform and the CTC system,the functional requirements of the CTC simulation system were analyzed,and the overall architecture and functional modules of the CTC simulation system were designed.Secondly,based on the requirements analysis of the CTC simulation system,the specific content and implementation process of each functional module were designed in detail,including the train graphs,dispatching command and temporary speed limit modules of CTC dispatch center system,route selection,command signing and logbook modules of the CTC station system,and public function modules such as station monitoring,network communication and teaching functions.Finally,the CTC simulation system is programmed and implemented on the Visual Studio2012 platform using the C ++ programming language and MFC framework.Combined with the laboratory CTCS-3 train control simulation platform,the real line information in the range from Huashan North Station to Lintong East Station on the Zhengxi Line is used as simulation data to demonstrate the simulation results of each functional module of the CTC simulation system.
