Better than moving mountains

Systematic tunnel automation – intelligent and highly available

Tunnels are actually the most ingenious element of the traffic infrastructure: They overcome the greatest obstacles using the shortest possible route. They also muffle noise and make traffic flows nearly invisible. They connect cities and communities with one another and ensure a higher quality of life. When driving through a tunnel, you have surely noticed the installations for illumination and ventilation before – as well as signal systems or life-saving emergency systems. These are modern tunnel automation solutions that we are implementing with our integrated portfolio.

The digital twin of your tunnel

Progressive digitalization has many clear advantages in the field of tunnel automation. The gains in efficiency that can be achieved with virtualization pay off, especially when it comes to planning, engineering and commissioning aspects. The digital map of a tunnel, known as the digital twin, enormously speeds up the engineering and commissioning processes. The gains in safety and availability are the most important operational advantages. Because digitalization opens up new opportunities here as well with regard to preventive maintenance and servicing. On the basis of data collected with the aid of Cloud technologies, e.g. MindSphere, impending faults, failures and subsequently occurring downtimes in the production process can be detected early on and the corresponding maintenance can be initiated. This allows continuous modernization and optimization of the tunnel without negatively impacting ongoing operations.

PROFINET

In addition to the worldwide proven PROFIBUS bus system, in the meantime PROFINET has established itself as a future-oriented, Ethernet-based fieldbus system. The data points that arise in the tunnel are connected to the fault-tolerant controller by means of PROFINET I/O systems via a PROFINET ring.
 

With the new PROFINET system, more flexible network structures can be implemented due to the different layout variants that PROFINET can provide. The trendsetting and Ethernet-based fieldbus system architecture provides a uniform standard, from the SCADA system up to the IO level.

PROFIBUS

With PROFIBUS, the world's leading industrial fieldbus system, a redundant ring for recording the control of data points in the tunnel can be implemented. The control system itself is operated in hot-standby mode. Optionally, a distance of up to 10 km can exist between the two redundant controllers.
 

The availability of the overall system can be increased due to the layout with a redundant I/O connection.
