Abstract: The structure of whole CBTC simulation test system and functions of each subsystem were introduced. Based on the study and analysis of line data, a scheme for line data visual display and generation was proposed. Both static model and dynamic model were constructed by using UML to explain the process of data generation. As for the storage of results, the line equipment information was saved using the database tables, and XML files were used to format the line topology information. According to the result of simulation testing, anticipative target was successfully achieved.
