摘要

With the extensive application of Weigh-In-Motion technique on highway, in this paper, the signal processing method of strip piezoelectric sensor is researched according to its output signal characters based on the development of Weigh-In-Motion system. Firstly, the time distribution of tire pressure of vehicles is deduced through the spatial distribution of vehicle's tire pressure. Secondly, the time distribution of tire pressure on sensor is deduced when the tire rolls the strip piezoelectric sensor based on the time distribution of tire pressure. Lastly, the calculated time distributions of tire pressure on sensor in dissimilar speeds are compared to the measured signals of strip piezoelectric sensor on spot, and then the signal processing method is obtained.
