Design And Research Of Distributional Automatic Train Supervision System Central Subsystem

With economic development and urban expansion, the society gives more requirements about the passenger transportation efficiency and its human services. The track traffic signal system is the orbital transportation command system, immediate influence operation and service. At the same time, it also sees that the signal system of China's rail transit is relatively backward technology, which has seriously hampered China's urban rail transit construction. Therefore one of the important tasks of our country urban rail transport construction is to realize the urban rail traffic signal system's manufacture domestically.The central sub-system of the Automatic Train Supervision System is the hub of the urban rail traffic signal system. The system has a direct impact on the entire rail transport capacity and efficiency of the system. It is not related to security systems so that easy to achieve manufacture domestically. Starting from the domestic and international current research situation, this paper deeply discusses the train automatic control system。After that this paper studies and analyzes the structure, function and main characteristic of central sub-system in Automatic Train Supervision System. It also studies the system by using object-oriented methods, based on this ,it studies the main function principle,system data structure and main control logic of the system.At present, the introduced of automatic train control system uses a variety of operating systems, both Windows and Linux operating system; Linux occupies most of the market share. Almost of domestic simulation platform based on Windows systems. Using wxWidgets to build cross-platform software simulation platform, not only will greatly enhance the construction of different operating systems on the efficiency of the software simulation platform, but also to the benefit of all kinds of operating systems based on the system. At last, it introduces the realization of computer simulation platform which simulate the software of central sub-system by using wxWidgets and multiple threads technologies, mainly including platform development environment,the key technology,frame and the realization of every function module.
