The Study of Improving The Speed and Precision in Weigh-in-motion System

摘要

In order to increase the speed by which the WIM system allows the vehicles to go through from it and improve the precision, the process of the system is analyzed and the physics and mathematics model of the system is introduced. According to the characteristics of the model, adapting the method of adaptive compensation with pole placement to shorten the transition time, and adopt FIR digital filters basing on haiming window function to decrease the effect of disturbance on the system, thus improve the speed and precision of the system.
