This invention discloses a signal post-processing method and apparatus for improving the accuracy of train passing identification, belonging to the field of high-speed railway condition monitoring technology. Based on candidate train passing events initially identified by existing methods, the method first performs time-domain waveform screening to eliminate events whose time-domain waveforms do not conform to a preset impact pattern.
