Research On Intercity Railway Train Control Simulation Training System Based On Multi-resolution Model

The intercity railway train control system is a complex system integrating multidisciplinary and cross-disciplinary fields such as computer,wireless communication and automatic control.Compared with the existing train control system,it has new features in system structure,equipment function and operation mode.The existing training methods on the railway site are difficult to be directly applied to the intercity railway train control system,which has caused certain obstacles to the application and popularization of the system.Therefore,the research on the training platform for intercity railway train control system is of great significance in system promotion,staff skill improvement and railway intelligent development.In order to solve the shortcomings of the existing training methods and combine theory with practice,the multi-resolution modeling method is used to study the simulation training platform of the intercity railway train control system in this dissertation.The system operation principle,fault situation and its solutions can be displayed from different angles and levels to meet the training needs of employees in different positions of the railway.The main works of this dissertation are as follows:(1)The hierarchical characteristics of the intercity railway train control system is analyzed from three aspects:structure,function and scene.The functional requirements of the simulation training system are proposed,and the target functional categories are determined.The framework of the simulation system is designed,which clarifies the follow-up research work from the three levels:scheduling,train and equipment.(2)According to the framework of the simulation system,three multi-resolution models are established including the train group section tracking model,the train automatic operation model and the equipment interaction and function implementation model.The hierarchical information and operation process of the system are studied,and the models are verified to ensure the correctness.(3)The MRMS formalization method is used to study the relationship between multi-resolution models.The structural changes of the system and the linkage between models are studied in the mathematical language.The consistency maintenance method suitable for the characteristics of intercity railway train control system is proposed,and the consistency maintenance process is designed to solve the inconsistency in non-concurrency situations.(4)The high-level architecture framework is used to simulate the system.The simulation federation definition,member division and the FOM design are completed,and the simulation management subsystem is designed to complete the federal operation control,resolution switching control and simulation result analysis.10 simulation training sequences are compiled,and the training effects of the simulation system are displayed according to the sequence contents,and the training objectives achieved by the system were verified.The simulation training platform established in this dissertation has been put into use at the production site of the GuanHui line electric power section.Through the feedback data,the training platform plays an active role in employee skill training,system cognition,and production skills improvement.
