The Train Wheel PtByPt VI reports on all wheels for all trains that pass through the data acquisition system. The Train Wheel PtByPt VI also reports any potentially defective wheels.

Every time a wheel passes the strain gauge, the Train Wheel PtByPt VI captures its waveform, analyzes it, and reports the event. The following table describes the components of a report on a single train wheel.

Information Source Meaning of Results
Counter mechanism for waveform events Stage One: Wheel number four has passed the strain gauge.
Analysis of highpass filter data Stage Two: Wheel number four has passed the strain gauge and the wheel might be defective.
Counter mechanism for end-of-train events Stage Three: Wheel number four in train number eight has passed the strain gauge, and the wheel might be defective.

The Train Wheel PtByPt VI uses point-by-point analysis to generate a report, not to control an industrial process. However, the Train Wheel PtByPt VI acquires data in real time, and you can modify the application to generate real-time control responses, such as stopping the train when the Train Wheel PtByPt VI encounters a potentially defective wheel.
