Method and apparatus for measuring dynamic loads produced by vehicles on a road.

摘要

A method for measuring dynamic loads using one or more piezoelectric sensors (30). The signal supplied by the said sensor (30) undergoes impedence matching (32) followed by controlled-gain amplification (35), sampling and conversion (36). The microcircuit (36) carries out the computation by single or multiple integration, controls the gain and corrects the value linearly or non-linearly as a function of the speed. <IMAGE>
