Abstract


Uninterrupted dynamic track scale is a large scale, which can weigh weight,verloading and partial load of the trains which keep moving.It is widely used in ports, mines, railways and other rail transportation and safety inspection.The test platform is constantly rail mode.when the train is running,the dynamic test data are measured.Installtion of uninterrupted dynamic track scale is simple and efficient.the data sensor detected must be analysis and processing and get an accurate weight of the train.The main contents are as follows:1. Analysis of continuous rail track scale test method and Customized design of based on the way bogie weighing weighing system;2. Analysis of the auto-detection vehicles, vehicle identification, digital filter, Removal of the train nose and the calculation of the train speed, completed a weight control system software design;3. Analysis of the empirical mode decomposition, Improved interpolation model of the algorithm and get a more stable interpolation curve.The improved empirical mode decomposition method is applied to the analysis of weight data obtained the weight of the train, and solve the issue of partial load;4. Data processing of the Hilbert-Huang transform applied to the dynamic weighing system data processing, and simulation results show its effectiveness and advantage.Paper introduces the principles of uninterrupted dynamic track scale and data processing of hardware and software.
