Abstract:
    This invention relates to a fault diagnosis system for underground locomotives traction circuit based on waveform identification, the output load of a tested traction circuit and standard load, in which, an embedded controlling machine picks up voltage input from both ends of the standard load, the end voltage of which is input into the input end of a data collector at the fore front of the controlling machine, the output end of which is connected with the input of an A/D converter, the output of which is connected with the write-in port of a data buffer storage, the numerate port of the buffer storage is connected with the readin port of a central processor, the fault database module of the tested circuit , the recording sign buffer storage, a software packet nodule based on a waveform identification algorithm realize dual way interaction by data bus and the central processor and the output of which is connected with the display output device by VGA.
