Design And Implement Of Enviroment Simulator For ATS System Test

With the development of economy and the improvement of industrialization,major cities have increasingly higher requirements on rail transportation capacity.In addition,the development and improvement of China’s rail signal system informatization provides technical support.More and more cities in China choose to upgrade or build subways using CBTC signal systems that can improve traffic efficiency and reduce equipment along the route.As an important subsystem of CBTC,ATS can realize the centralized supervision and adjustment control of the signal equipment of the entire line,and assist the operation professionals in the operation management of the train operation of the entire line with the assistance of other subsystems.However,ATS has the disadvantages of on-site condition limited training,complicated system testing process,and high time cost in practical application and on-site testing.To solve the above problems,this thesis designs an environment simulator for ATS system testing.First,the theoretical basis of the structure,principles,and models of the CBTC and ATS systems are studied,and on this basis,from the overall system architecture to each module,requirements analysis and functional design of the environment simulator for ATS system test are carried out.Second,the environment simulator is designed and implemented in detail,including the data structure of the station diagram,the initial display of the station diagram,the interface operation function,the design and implementation of the communication module,and the train operation simulation and scene realization of the key research.The train operation simulation function is designed through the train data requirements,positioning display function,automatic route triggering function,and driving data processing,and on this basis,the train operation scenario is analyzed from the two aspects of principle analysis and data command,which includes the main line tracking operation,platform parking and train return.Then,the detailed design and implementation of the function test of ATS system,including ATS system test data,interlocking data structure,communication data display interface,interlocking module,etc.In addition to the commonly used route control functions,the interlocking modules that are mainly studied include a fault simulation module and a signal device control module that provide a logical operation basis for the manual operation function of the environment simulator interface and the dynamic commands during driving,so as to realize route control,fault simulation and signal equipment operation logic and drive function.Finally,the environment simulator is combined with the interlocking and external VOBC through the communication module to conduct simulation test on the environment simulator for ATS system test,and verify the realization of the above basic functions and the dynamic graphical display of common train operating scenarios,so as to simulate the on-site environment and achieve the intended simulation purpose.
