As part of this project, Médiane Système has developed a system for measuring and automatic acquisition by optical cells to track the movement of the cardboard through the various elements constituting the machine in real time. The optical cells are arranged at different places on the machine: these cells detect the front (AV) and rear (AR) edges of the cardboard, which makes it possible to deduce the measures of register and cross variation by element. Médiane Système has developed and produced an acquisition box in charge of acquiring the signals coming from the cells and which interfaces with a PC through an Ethernet link. Médiane Système also realized the software of parameterization, acquisition and treatment of the results.
Technology used: Windows Seven, LabVIEW, LabVIEW FPGA, Banc de test, Cellules optiques, Extension Rio.
