Calsens team has carried out the design and installation of a permanent and remotely controlled monitoring system in real time for the structure of the metal bridge of Line 9 of the Alicante TRAM Network of FGV over the Algar river. The system monitors the structural health of the viaduct 24 hours a day, through a system composed of more than 100 optical sensors, connected remotely and directly to the IoT platform developed by Calsens, in which the post-processing of the data collected occurs in real time.
