High-Tech under the Ground - WinCC employed in the Control and Safety Systems of the Engelberg Tunnel
|
|
|
|
From the viewpoint of travelers, road tunnels are above all enormous
structures that help avoid long detours and shorten distances. Few notice that
sophisticated control and automation equipment -located behind the spacious
concrete tubes - is employed to ensure trouble-free and smooth operation
around the clock.

As a matter of fact, a multitude of variablesneed to be measured, controlled and regulated. This means that
in both pipes of the Engelberg base tunnel, there are 29 CO sensors, 16
blurred vision test points, 4 NOx sensors, 70 optical smoke detectors, 15
colour cameras, 39 emergency alarms and a large number of other measuring
instruments for the direction of air flow,wind speed, temperature and other
parameters.
