| The Beijing-Shanghai high-speed railway is the representative of the passenger dedicated lines, which reaches a speed of 350 km/h. Its construction and operation urgently requires high-speed detection trains to provide technical support for new line acceptance and periodic check. Balise detection is an important content of high-speed test train. Currently, there is no balise detection system for the use of high-speed on abroad. In China, the "No.0 high-speed comprehensive testing train" has achieved the balise detection for a speed of 250 km/h. But the data processing subsystem does not have a complete data processing functions for the balise electrical parameters. This thesis relies on the project "High-speed railway track circuit, the balise detection technology", which is the sub-project of "Maximum testing speed of 400km/h high-speed testing train" in National High Technology Research and Development Program (863 Program). The thesis will make a thorough research on the requirements analysis, architectural design, detailed design, realization and debugging of data processing subsystem of balise detection system.This thesis covers following aspects:1,Through literature review, analysis the application status of high-speed comprehensive testing train, signal detection system structure, balise system theory and testing system configuration;2,Establish information flow model of the balise testing system, and use UML to analyze functional requirements for the data processing subsystem and given the system's use case diagrams and activity diagrams;3,Design the overall software architecture based on UML and given the class diagrams, sequence diagrams and state diagrams;4,Design the system's network connection module, display module and the data manipulation module. Complete programing of the data processing software based on Labwindows/CVI development platform;5,Completion of system debugging and simulation.This thesis basically realize the functions of data processing subsystem of balise detection system for high-speed comprehensive inspection train, including balise testing data analysis, storage, display, query, playback and other functions, which provided the conditions for balise detection system joint debugging and realization. |
