Abstract: TIS integrates the interfaces and functions of the computer based interlocking system and the train control center system, which brings a number of advantages in field equipment maintenance and real-time system control, but also brings the complexity of software functions. Considering that the equipment needs to have better maintainability and operability in the field, it is divided into levels from the functional structure. For example, the station interlocking relationship, section signal control, track circuit coding, etc. are taken as the functional requirements of CTCS-0 train control system lines, and the temporary speed restriction and switchable balise function are taken as the functional requirements of CTCS-2/CTCS-3 train control system lines. Combined with the data configuration, multi-level modular management can be carried out. The software is designed in structural method with independent modules. The data configuration and software upgrade of different functions do not affect each other, and the coupling between different functional modules is reduced. This is not only conducive to the project implementation, data configuration, software maintenance and fault analysis and location, but also conducive to the analysis of the overall safety of the system.
