Research And Implementation On Train Station Graph For The ATS Based On CBTC

Based on CBTC (Communication Based Train Control), Automatic TrainSupervision (ATS) system mainly implements the function of monitoring, controlling,and manually managing the running trains of the whole line from human-machineinterface of the ATS with the dispatcher.As the most important human-machineinterface of the ATS, Train Station Graph reflects the precise position, type, drivingmodel, the direction of trains and other information in real-time, and meanwhile, adjuststhe status of the train running.This thesis overviews the state and development trend of domestic and foreigntechnology, system architecture, system principle in CBTC, and meanwhile, analysesthe system structure of the ATS based on CBTC, and then studies and implements thehuman Train Station Graph.Firstly, the paper elaborates the design principles of Train Station Graph.Secondly, the paper analysis the composition, data structure design, interfacedesign and drawing of Train Station Graph.Thirdly, the paper elaborates the back-office services support of the line of the train,train positioning, appropriative and human-machine dialogue in Train Station Graph,which includes the following parts:1. The algorithm of Depth-First-Search and Breadth-First-Search can search linesof Train Station Graph and complete the path data of the running train.2. Train Station Graph receives the real-time data of the Compatible DevicesClasses in ATS and refreshes the status of signal devices in Train Station Graph, inorder to implement the train positioning and display of the train ID.3. Train Station Graph provides appropriative and human-machine dialogue is tomanually adjust the status of the signal equipment and the running train.4. By simulating the running of the train is to verify the realization of the basicfunctions in Train Station Graph.Finally, the work of the project is summarized, and a prospect of the further work todo is made as well.
