Low-Frequency Encoding Data Inspection Software Of Track Circuit Encoding Module For Train Control Center And Interlocking Integrated System

CTCS-2 and CTCS-3 systems have been widely used along my country’s railways.With the development of technology and the needs of high-speed railway operations,the next generation of more advanced train control system signal equipment is also actively researched and developed.In order to reduce the problem of interface failure between systems and improve the management efficiency of the system,signal system equipment integration is a trend in the development of railway signal equipment,and train control center and interlocking integrated system is a representative technology for equipment integration research.In the active research and development process,the signal equipment of train control center and interlocking integrated system may have undiscovered software logic design defects that endanger driving safety.Therefore,how to effectively find defects and errors at the level of software design and implementation,and improve the reliability of the equipment and the credibility of the software are problems that must be solved in the process of equipment development and software development.The thesis takes track circuit encoding module of the train control center and interlocking integrated system as an example to design an inspection software,which can inspect the low-frequency encoding data of the track circuit encoding module of the train control center and interlocking integrated system.This thesis firstly realizes the requirement analysis of low-frequency encoding data inspection of track circuit encoding module from the five aspects of dynamic data,function analysis,inspection method,software structure,inspection execution process.Secondly,the UML language is used to complete the modeling design of the inspection software,and the functional requirements,static structure and dynamic interaction behavior of the inspection software are clarified.Then,using C#language to program the low-frequency encoding data inspection software of the track circuit encoding module,which mainly includes static data initialization function,data communication function,and inspection function.Finally,in the virtual simulation environment,the test of the low-frequency encoding data inspection software function of the track circuit encoding module is completed through the fault injection technology.Through the work of this thesis,the inspection of the logical correctness of lowfrequency encoding data of track circuit encoding module of the train control center and interlocking integrated system has been achieved,and the operation status of track circuit encoding module of the train control center and interlocking integrated system has been monitored,and the design defects and errors at the software level have been inspected in advance.The purpose is to avoid the occurrence of logic errors in the track circuit encoding module,and to improve the reliability and operational safety of the train control center and interlocking integrated system.The method of inspection the low-frequency encoding data of the track circuit encoding module in this thesis is also applicable to the inspection of other functional modules in the train control center and interlocking integrated system.
