Abstract

An axle load scale with a load signal generation portion having a platform receiving an axle load of a vehicle running for generating a load signal according to the received axle load. The platform being a given size in a running direction of the vehicle and the axle load shows a sinusoidal variation with running of the vehicle The load signal shows a waveform including a top slope reflecting a portion of a waveform of the sinusoidal variation and a net weight of the axle load; a sinusoidal variation prediction portion for predicting the sinusoidal variation from the load signal; and a net axle load prediction portion for predicting and outputting a net axle load value from the predicted sinusoidal variation. The sinusoidal variation prediction portion predicts the waveform of the sinusoidal variation of axle load through detecting a magnitude an inclination of a detected top slope of a pulse of the load signal or the least squaring method. N load signal generation portions having N platforms arranged in a path of the vehicles generates intermittently continuous waveform of the sinusoidal variation, so that a waveform detection portion for detecting the intermittently continuous waveform and the net axle load prediction portion predicts similarly.
