Primarily, the paper demonstrates that the importance of the development of the subway for the development of our national economy. Then, with citing the development experiences of the other developed countries in the world, it shows that our country’s economic development is inseparable from the development of the subway system. Currently, the metro is the stage of rapid development in our nation. So, there is a lot of demand of the related operators and dispatchers to the subway system, and then the training of these personnel is to ensure the normal and safe operation of the subway system, one of the important guarantees of safe operation. Therefore, design of the subway signal simulation is definitely necessary. This requires a simulation system to simulate, which is with real similar to the subway signal system. So, the design of the subway signal simulation system is very necessary. It is clear that the research work for this project to improve the personnel operations and ensure the normal security of the actual subway system have a very important social significance.Based on my participation in the actual project in the Shanghai electrical automation R&D Institute, the paper describes the design and implementation of the subway signal simulation system in detail, and the same to many other aspects. First of all, this paper analyzes the function of the actual operation and the requirements of subsystem based on the depth analysis of the subway signal system, in order to determine a series of functional requirements of the subway signal simulation system. On the other hand, from the perspective of software design we analyze the software architecture of the system and design specifications and software development methods and software architecture development method. According to the functional requirements and system software design principles of subway signal simulation system, from the perspective of subway operations and signal logics to design the subway signal simulation system. One of the key points of the signal simulation system is the database which should be with detailed design and analysis. Finally, the simulation system uses the Microsoft Visual studio 2008 as the development platform and SQL Server 2008 as the database software, using C# to achieve the design of the various modules in the subway simulation system, and then integrate the modules. At last, the overall functional requirements of the signal simulation system will be achieved.In addition, in view of the simulation system to train various types dispatchers, operators and some other people in the subway system, it makes user-friendly, simple, approachable, simple but not monotonous of the interface as far as possible when it was designed, which will make the trainees feel comfortable and relax, then it will become a subway signal simulation system that truly widely promoted by the subway system. In view of the using of the system, the subway signal simulation system achieves to simulate urban rail transit train traffic for monitoring the implementation of daily operations. What is more, it makes the trainer feel that they are working on the edge of the territory which will build a better foundation for the safe operation of the subway. In addition of training, it also increased the editing module of the basic data that it is more helpful for operators to understand the subway signal system.
