Research On Environment Simulator Of C3 Train Control Simulation System

The CTCS-3 is a train control system based on wireless information transmission,the locomotive flight attendant is driven by the vehicle signal and used for the line of 300-350km/h.The C3 train control system has the characteristics of complex control principle and high safety requirements,but the field test has the disadvantages of large manpower and material consumption,therefore,it is necessary to develop a simulation test platform that meets the C3 train control system standard.The perfect train control system simulation test platform not only can quickly and repeatedly test,but also test the functions in different operating scenarios,with the advantages of less capital investment,flexible configuration,safe and efficient,and a large amount of static data and dynamic data made in the simulation test process,through the analysis of the data,it is easy to solve problems in the test process.This thesis mainly discusses the structure design and function realization of the environment simulator module in the C3 simulation test platform,the main research contents are: combined with the specific requirements of the C3 simulation test platform project and the overall technical content of the C3 level control system,the environment simulator module performs detailed requirements analysis;based on the real line basic data information provided by the design institute,realizes the data structure and database table design of different objects;using the computer programming language and database software developing interface,and completed the realization of the functions of the three sub-modules in the software.The functions of the train dynamics calculation sub-module include: train force analysis,train running state analysis,train speed and position calculation.The functions of the virtual trackside device sub-module include: ground transponder activation and message transmission,track circuit occupancy check and code sequence transmission.The functions of the random fault information injector sub-module include: random fault information generation,random fault information injection,and comprehensive information analysis;the environment simulator realizes communication with the ATP,TCC,CBI,RBC through interface communication,the data interaction enables the C3 simulation test platform to perform joint debugging and joint testing to realize the collaborative work of the system.Combined with the content of the above research and the final simulation test results,the environmental simulator of this thesis has the functions of simulating train speed and position,virtual trackside equipment and random fault information,and has the ability to test fault information of other C3 platform sub-modules.
