In a typical year, over 35 million passengers and 96 thousand tons of cargo pass through the Barcelona El Prat Airport. AENA is responsible for airport operations, and its smart airport solution boasts a dynamic, intelligent infrastructure. The control environment handles over 1,000,000 signals and includes control of all escalators, elevators and passenger moving walkways; power management; air conditioning; and fire safety systems. It also involves monitoring support for the automated luggage transport system. This fully integrated, multi-hardware solution was made possible with the help of Wonderware software.
