Design And Verification Of CAD Used For Train Control System Dedicated For Passengers Based On CTCS-2

Train Control Center system is an important device in the CTCS-2 level transponder that can select message and send it from transponder, it was based on a temporary speed limit orders generated by the command system and current state of the interlocking system and then calculate, select correct transponder message data, control the dynamic active transponder sent to train in order to achieve dynamic operation of train control. Transponder packets of information generated according to different conditions of the temporary speed limit and approach will be pre-coded and stored in the center control system. The column then select appropriate transponder message according to condition in the field and send it to equipment in the train through ground equipment such as LEU.In this paper, aided design system used in ground equipment that based on computer which is contained in CTCS-2 level Train Control System will be researched. It changed the way for designing current CTCS-2 level control system which is inefficient, of low quality and it can design the project for ground signal system of train for passengers automatically and intelligently. It can improve the efficiency and quality of the design work for signal project greatly. This paper analyzes the system requirements, describes the research background and significance of the system; According to the overall system requirements and related needs of each module, in accordance with the software engineering of the system architecture, it mainly discuss the access to the original EXCEL format data and check for its format, the generation and storage of the graph for the system, the design way for the access module, the draw module, the print module and the message print module. Then the whole system is designed. This paper describes the main function blocks:lines slope simplified module, line speed merge modules and so on and the the detailed design methods is also described; Finally, the system interface and operational processes are introduced.
