Simulation And Research On Active Balise Telegram And The Managing Of Temporary Speed Restriction Module Of Train Control Center Simulation System In Passenger Railway Lines

The train control center of train station is the core equipment of train control system in passenger railway lines. It is not only active to achieve the control of active balise message output and the checking and executing of temporary speed restriction,but also responsible for those functions such as ZPW-2000A/K track circuit code,the logic of section signal lighting, inter-station communication, direction-changing of section and station.The train control center takes on the major responsibility for traffic safety,therefore,it is necessary to do some research and improve the function of it.However, the constructure and functional requirements are so complicated, and there are too many communicaton interfaces, and it costs a lot. So it is difficult to do research with actual equipments in laboratory circumstances.As a comprehensive method which has been using for many years, simulation has replace the entity and has character of economical, safe, and efficiency.The computer simulation includes active balise message generation process, the check and execution of temporary speed restriction, and the output of active balise's telegram, and the application of the model such as track circuit code and direction-changing in section, this method means too much about saving expenditure and research on the actual train control center.The main contents of this dissertation includes introduction,the analysis of train control center simulation system, analysis of active balise telegram module,the analyses of active balise telegram data, and the generating of active balise telegram and the managing of temporary speed restriction.Based on the analysis of the simulation of the train control center system, this dissertation analyzes the requirement of the generating of active balise telegram and the managing of temporary speed restriction module. The software design is under the standard for software design principle and system demands. This dissertation describes the detail design method of the primary function modules which consists of generating of active balise route telegram, check and executing of temporary speed restriction, the generating of temporary speed restriction telegram, and active balise telegram packet and sending. At last, it has well reached the purpose of systematic function simulation through debugging systematically.
