| Abstract: | To meet the practical demands of vehicle safety detection in Shanghai rail transit Pearl Line, this paper proposes a general plan for the adoption of DSP technology to collect vibration signals, introduces the hardware support in detecting the flat wheel and its software design flow. As the result shows, the DSP technology could accomplish high-speed, multi-channel data collection and thus ensure the reality and validity of the signal data in detecting the running cars, which are demanded by data analysis. |
