Data relating to error reports and monitoring is sent to the cloud to enable better monitoring of both the Saarlouis central energy supply and a well system. The program’s success has led the German city to consider expanding the cloud projects.
Between 1824 and 1829, when the Prussians expanded parts of the old fortifications from the Thirty Years’ War into command posts and housing for soldiers, horses and provisions, they created a bomb-proof project. To this day, the historical ramparts, the so-called casemates, form an important part of the Saarlouis cityscape. However, their use has changed fundamentally: Restaurants have been set up under the arches and attract visitors from near and far to the longest buffet in the Saarland. But though the casemates are easy to reach from the center, they are far from the telecommunications network. Data connections are therefore difficult to establish, even though they are important for regulating the local district heating used by ten cafes and restaurants. The energy control center, with two pumps for providing hot water to the restaurants, is installed at the head of the casemates. If they fail, guests will get cold feet, since a great deal of time can pass before the damage is reported, a city employee gets to the site and the problem is solved.
