Abstract

High speed railway signal system works in the complicated electromagnetic environment. During the interference analysis and data processing, a universal platform for various analog and digital signals should be established. An integrated data processing platform based on LabVIEW software was developed, consisting of data acquisition, data format conversion and signal processing. The platform can collect the signals of the analog source, and import the data stored in the recorder, thus constructing a universal processing platform. On this basis, the impact of the transient characteristics of high speed railway traction current on the signal was analyzed, and the detection of singularity of transient interference based on wavelet analysis was accomplished. Finally, by processing of the actual waveform recorded at the railway site, the validity of the platform function and algorithm were verified. The functions of the signal processing include real-time measurement in time domain, waveform display, filtering and spectrum analysis.
