IN-MOTION WEIGHING SYSTEM FOR MOTOR VEHICLES BASED ON RIGID AND FIBER OPTIC SENSORS

The present invention relates to a weigh-in-motion system for motor vehicles based on a set consisting of loop sensors and fiber optic sensors mounted on a rigid metal profile. Its technical field of application corresponds to systems for measuring dynamic physical events that are caused directly or indirectly by the passage of a motor vehicle over its sensors. The rigid weighing sensor is made of rigid or semi-rigid metal, plastic, composite or similar material, with a deformation profile optimized for transforming vertical stresses into horizontal stresses and containing damping and protection material to attenuate external horizontal stresses. This set makes it possible to measure parameters with high precision and in a reliable and simple way, with the advantages of being installed and molded to any floor, of being minimally intrusive, of not suffering electromagnetic interference, of being low cost, of having a long service life, and of having simple manufacturing technology at a lower cost than that demonstrated in the state of the art.
