The Design And Realization Of CTCS2+ATO On-board Subsystem Training Platform

Rapid development of high-speed railway in our country has achieved a larger range of high-speed transit, while for developed regions, the region of small-scale transport requires the inter-city railway. As passenger-dedicated railway, the inter-city railway is fast, convenient and high-density. The inter-city railway train control system varies in form, such as the inter-city railway of Beijing-Tianjin adopts the ETCS-1 level train control system, and the inter-city railway of Shanghai-Nanjing adopts the CTCS-3 level train control system. For the first time, Guangzhou Railway Bureau adopts CTCS2+ATO train control system. Compared to the other train control systems, CTCS2+ATO train control system has the advantages of both high speed-railway and urban rail transit, and it realizes not only the high speed of the train operation but also the automatic operation of the train, further improves the operating efficiency of the train. CTCS2+ATO, however, the proposing and application of the new system scheme put forward the new challenges for train drivers and related maintenance personnel. So the study of CTCS2+ATO train control training platform has important practical significance.First, based on the analysis of CTCS-2 levels of train operation control system specification and inter-city railway CTCS2+ATO train control system interim general technical scheme, this thesis studies and analyzes the functional requirements of the training platform.Second, starting with the overall design scheme of CTCS2+ATO train control system and combining with the training content and the requirement analysis of the field personnel, this thesis sums up four training parts of the platform, which are operating scenarios, patterns, functions, mode conversion and automatic train operation. Training points are distilled from every part, and the principle and operation logic of the training point are analyzed. According to the results of above analysis, combined with data of Guanhui lines, all scenarios of the training points are analyzed and designed. Based on all scenes of the above training points, all the training sequences are designed.Then, according to the requirement analysis of the system, overall scheme of the training platform is designed. The training platform mainly consists of three modules and has two modes, which are the training mode and learning mode. In the mode of training, trainees can drive the train in simulation environment by running sequence, and the linkage of the training interface realized to makes the interpretation of training point, station higure display, DM1 operating synchronously. As supplement of the training model, learning model allow the trainees to browse and review the training points when they have basically grasped the principle and logic of training points.Finally, with the.NET Framework 4.0 as development environment, this platform is developed by using Visual Studio 2010 software development tool, SQL Server. In order to achieve the overall control of the system, the platform applies.NET Remoting technology. The platform can run sequence, also can display simulation driving and training points’instruction in sync in the training mode; at the same time training points’ explain and switch between the two modes are applied in learning mode.
