Design And Implementation Of Interface Software For Train Control Center Simulation Test System

With the gradual networking of Chinese high-speed railways,many new high-speed railway lines need to get access to the existing high-speed railway network,causing the transformation of the signal system of the hub station.The transformation has brought a lot of works and difficulties to the test of the train control system in hub station.On the one hand,the hub station has complicated lines and many kinds of equipments,which makes the transformation test of the train control system complex and huge.On the other hand,because of the transportation tasks at the hub station are busy,and the limitation of condition.It is difficult to ensure the quality of the test for the train control system's transformation.Moreover,the on-site system test will affect safety of the line transportation,and the contradiction between the transformation task and the transportation task is serious.As the core control device of the CTCS-2 train control system,the function of train control center(TCC)is complex.The on-site manual test method will greatly affect the transformation progress and test coverage of the train control system.Through the development of the TCC simulation test system,the work originally relying on the manual test can be transferred to the simulation test system,which can greatly improve the efficiency and quality of the train control system transformation test,and reduce the conflict between the transformation task and the transportation task.Combining the functional requirements of the high-speed railway TCC simulation test system,the paper designs and implements the interface software of the TCC simulation test system.The interface software can realize the interface data encoding and decoding function between TCC and Computer Based Interlocking,Temporary Speed Restriction Server,Centralized traffic control and TCC,and the network communication management function for realize data interaction between the simulation test system and TCC.The interface software is designed in detail using UML modeling language,and is programmed by C++ and Qt.Finally,the thesis introduces a laboratory test environment for the TCC simulation test system,and tests the interface software with a real TCC device.The test results show that the interface software can accurately and quickly complete the codec work of interface data,and has good usability.
