Research On Interface Technology And Application Of Train Control Center

In recent years, the rapid development of China’s high-speed railway has made remarkable achievements, CTCS train control system technology has also made great progress. The Train Control Center(TCC) is the ground core equipment of the CTCS train control system, which is connected with other systems through different interfaces to perform information exchange to realize the operation control of the high-speed train. Therefore, TCC interface technology is very critical in the train control system. This paper focuses on the TCC interface technology in the field of application, analyzing the reasons for TCC interface failure, researching fault treatment plan, and according to the technical characteristics of the interface of the train control center, combined with the actual situation of the field, developed a set of measures to improve the application interface technology.This paper briefly introduces the principle and structure of the train control system, expounds the information exchange between the Train Control Center and the related system through the Train Control Center interface, and briefly introduces the content of the interaction. Three physical interfaces between the Train Control Center and the other systems are described, and the constitution of physical interface is introduced. In addition, it also briefly introduces the railway safety communication protocol used in the communication of the train control system and other systems.Secondly, this paper makes a deep research on the interface standard of the Train Control Center. The communication methods and contents of the Train Control Center and other systems are analyzed, including the interface topology map, the communication cycle, the communication data, the communication failure mechanism and so on.What’s more, this paper focuses on the Nanning Railway Bureau as an example to analyze the field application of the interface technology of the train control center, and obtains the high security and stability of the application of the column control center interface technology; through the statistical analysis of telecommunication section Train Control Center fault conditions, get the ratio of the train control center interface failure. Then analyzes the interface failure between the train control center and other systems, focusing on the cause of the fault and the disposal process, put forward the existing problems and deficiencies.Finally, in the full study of the Train Control Center interface technology in the field of application, the paper inductive analyzes train control interface fault reasons and on the basis of this, a set of effective measures to reduce the fault of the interface of the Train Control Center and the test content of the interface of the Train Control Center are studied.
