Provide the automation system for keeping the longest tunnel in the Balkans, in optimal safety conditions.
SOLUTION
RESULT
Integrated total solutions that meet stringent safety requirements.
Subcontractors for SIEMENS for the automation of the SCADA/TMS system for the three tunnels under construction in the region “Tempi Valley”.
The 3 tunnels have a total length of 11 km (2km, 3km, and 6km). The third one is the longest in the Balkans and bypasses the winding and rock slide – plagued Tempi Valley on the main Athens-Thessaloniki highway.
The project has more than 20.000 control points. The automation is supervising and controlling the following tunnel subsystems: Lighting, Ventilation, Fire Detection, Fire Fighting, CCTV, Emergency Roadside Telephones, Radio communication, Power Supply distribution system, EDGs, Network Supervision, Traffic Data Counting System and Traffic Management System (TMS).
Subcontractors for SIEMENS for the automation of the SCADA/TMS system for the three tunnels in the region Tempi Valley and Platamonas.
The 3 tunnels have a total length of 11 km (2km, 3km, and 6km). The third one is the longest in the Balkans and bypasses the winding and rock slide – plagued Tempi Valley on the main Athens-Thessaloniki highway. There are more than 20.000 physical control points and network measurements.
The automation is supervising and controlling the following tunnel subsystems:
We designed our solution around SIEMENS SIMATIC S7-400H for a fault-tolerant automation system, which minimizes the probability of failure to nearly 0%!
In each tunnel, we used the CPU 417-5 H controller to collect all the control signals and perform the automation program. We used the SIEMENS ET200S series in 120 remote I/O stations, for the benefits of the highest quality and the extremely rugged design.
Some of the most important technical aspects of this project are summarized below:
The Motorway Management System (MMS) in the control room of the three tunnels always has a full picture of the traffic conditions and oversees the safe operation of the motorway. Incidents are immediately acknowledged to allow for quick and efficient response.
System operators can see the operation of all control points and alarms in real-time, while they can remotely control most of the equipment.
This is a major infrastructure project in Greece with major benefits. The drivers experience uninterrupted and constant traffic flow even in adverse weather conditions, cleanliness and respect for the surrounding area, and maximum road safety and economy! At the same time, the region benefits from the provision of many direct and indirect jobs and environmental protection of the Tempi Valley due to reduced pollution levels!
