The System Of Tracking Test Data Management And Analysis

For system analysis of climate (temperature, wind, rain and snow), line conditions (track, more tunnels, more bridges), the use of different maintenance and use of mileage (wheel wear, etc.) on the EMU service performance, the proposed high-speed EMU as the center of key parameters of the system through long-term tracking test, grasp the EMU in the dynamic behavior of high-speed operation and its service time with the variations arising.This track trials for mass data management and analysis technology research, design a file format based on HDF5 hierarchical superiority, Python language is simple, flexible and Delphi2007 user-friendly, practical high-speed rail track in the experimental data processing system. Purpose is to facilitate data processing personnel to master high-speed EMU in the dynamic behavior of high-speed operation and its service time with parameter changes resulting from the trend of critical system performance, reliability and security issues to study, to optimize high-speed train design and development to provide a reasonable basis for repair and maintenance cycle, thus establishing the key components in service time with the database.Paper first introduces the domestic and international data management and analysis of existing technologies, and the advantages of HDF5 file format, illustrates the combination of the HDF5 format and python applied to data management and analysis system advantage. Starting from the general to determine the system's various functional modules. Including: document management, data processing, data, graphics, search functions and so on. Secondly, is introduced in the system design applied to the specific strategies and methods, which include Delphi, Python and HDF5 library data communications, software interface, functional design, data analysis algorithm, designed graphical display of data, etc. Finally, practical application software problems, make the software needs to improve.Results of this study show that:Based on HDF5 file format for data management and analysis system in the tracking experiment, data processing is feasible, it is not only vast amounts of data tracking experiments have played a good management role, and their product time-domain analysis, frequency domain analysis, as well as comfort and stability characteristics of graded-in-one, but also facilitates the data processing speed of data processing staff and deal with reports, picked up speed. And Delphi visual development environment, and easy to learn Python to speed up the developer's development speed.
