The measurement system consists in 3 optical boxes based on laser triangulation technology, that allow contactless measurements with high levels of accuracy. The geolocation of the measurements is guaranteed by a GNSS unit, combined with an odometrical system that calculates the displacement using a quadrature encoder. All the measurements are referred to the center of the running surface, thanks to a compensation system that allows monitoring of the horizontal and vertical displacements of the coach body. All the defects detected are saved in a file and sent to the infrastructure manager who can post-process the data and proceed with its maintenance.
