METHOD FOR COUNTING AXLES WITH COMPUTER-AIDED EVALUATION

Abstract Method for counting axles with computer-assisted evaluation The subject matter of the disclosure is a method for counting axles, in which an axle counting sensor installed on a track is passed by a wheel, the axle counting sensor generates a measurement signal (Ul... U2) and the waveform (VL1... VL2) of the measurement signal (Ul... U2) is evaluated on a computer assisted basis and thus the wheel is identified. During the evaluation of the measurement signal (Ul... U2), at least one maximum (Ml... M4) of the signal amplitude is searched for in the waveform (VL1... VL2) of the measurement signal (Ul... U2). The amplitude of the measurement signal (Ul... U2) is normalized during an amplitude normalization in such a manner that the maximum (Ml... M4) is identical to a predefined target value (ZW). A dynamic time normalization is performed before and after the maximum (Ml... M4) for the waveform (VL1... VL2) of the measurement signal (Ul... U2). The waveform (NV1... NV2), which has been normalized by amplitude normalization and time normalization, of the measurement signal (Ul... U2) is compared with patterns (Ml... M2) both of at least one waveform (VL1... VL2) for the measurement signal (Ul... U2) when a wheel (RD) passes and of at least one waveform (VL1... VL2) for the measurement signal (Ul... U2) when an error occurs. The disclosure further comprises a computer program product and a provision apparatus for the computer program product.
