Abstract

A portable, multi-function WIM sensing system based on Fiber Bragg Grating (FBG) technology is developed to measure the total weight, the distribution of weight of vehicle in motion (the weights of left front, right front, left rear and right rear wheels respectively), the distance of wheels axles and distance between left and right wheels. Currently the speed of vehicle to be tested can be up to 15 mph, the full scope of measurement for this system is 4000 lbs, and the static sensitivity of sensor head is 20 lbs. This system has been tested respectively at Stevens' campus and Army base. Compared to other schemes, our method has a number of advantages such as immune to electromagnetic interference, high repeatability, lightweight, low power consumption, high sensitivity to dynamic strain caused by load of vehicles in high-speed. The accuracy of whole system can be improved by simulating the mathematical model of sensor heads and improving the quality of manufacture as well as the calibration condition in the future.
