BRIDGE WEIGH IN MOTION SYSTEM USING REACTION FORCE OF SUPPORTING POINTS AND METHOD FOR CONTROLLING THE SAME

摘要

The present invention relates to a BWIM system using the reaction force response of supporting points capable of measuring a load response caused when a vehicle passes using bridge bearings on which a sensor for measuring vertical load is installed to accurately and conveniently obtain the axle weight, the gross weight, the distance between axles, and the driving speed of the passing vehicle In order to calculate the load of the vehicle through the reaction force measurement using the bridge bearings, the present invention comprises: a load response measuring and preprocessing part for measuring the reaction force response caused by the vehicle passing a bridge and preprocessing the data on the measured load response; an axle number determining and wheel base calculating part for determining a number of the axles of the passing vehicle and calculating the distance between the axles of the passing vehicle; a passing crossroad determining and passing speed calculating part for determining a passing crossroad of the vehicle passing the bridge and calculating the passing speed of the vehicle; and an axle weight and gross weight calculating part for calculating the axle weight and the gross weight of the passing vehicle.
