Challenges

  • Tight deadline pressure - Project had to be completed on time for the 2004 Summer Olympics in Greece with no room for delays.
  • Complex system integration - Managing 25,000+ I/O points across tunnels, lighting, ventilation, and emergency systems required sophisticated coordination.
  • Critical safety requirements - Monitoring air quality, fire systems, and emergency response in tunnels demanded zero-failure reliability standards.

Results

  • Fast emergency response - System response time under 2 seconds enables rapid identification and handling of emergency situations on the motorway.
  • Centralized control efficiency - Operators gain complete real-time visibility of all highway systems from a single monitoring location.
  • Olympic success delivery - Project completed on schedule, successfully supporting Athens' infrastructure for the 2004 Summer Olympics games.

“This monitoring and control application was designed and integrated on time by Algosystems SA in Athens, Greece. The SCADA graphics are very impressive, and the system allows our operators a complete picture anywhere on the highway. The system provides a fast and reliable centralized tool for our emergency personnel and support team. The GENESIS software helps make the Attiki Odos a world-class motorway.”

About Attiki Odos Motorway

The Attiki Odos Motorway is one of the most modern motorways in Europe. The highest standards have been observed in its design. The motorway extends over 60 km, is four lanes wide, and has 32 multi-level interchanges and hundreds of overpasses. The Attiki Odos uses the most modern equipment for incident detection and emergency response.

Software Deployed

GENESIS is used in a redundant configuration along with AlarmWorX™. The redundant GENESIS servers are responsible for the monitoring and control of all electromechanical equipment for the tunnels and highways. This includes the lighting and tunnel ventilation systems. The air quality within the tunnels is monitored, and GENESIS can allow exterior airflow, as needed, to keep the tunnels clear of carbon dioxide, smoke and nitrogen oxide.

Key Features

In addition to controlling the lights and ventilation system for all the tunnels, GENESIS software is also responsible for other systems within the Attiki Odos motorway. All emergency fire hose panels, irrigation pumps, power distribution (medium and high voltage), UPS systems and diesel generators are monitored and controlled by the GENESIS software. MSDE is used for all data logging.

Project Summary

Mitsubishi Electric Iconics Digital Solutions’ software system was installed at Attiki Odos to centralize motorway operations and provide the status of all electromechanical systems. The SCADA system enhances the ability of motorway operators to easily identify and handle emergency situations and overcome malfunctions of equipment in order to provide better quality of services.

With over 25,000 I/O points, the redundant GENESIS servers are interfacing in real time with Opto22 LCM4 redundant controllers and LCSX-Plus controllers over an Ethernet network. The system response time is less than two seconds. GenBroker is used to enhance communication of operator workstations with servers. Algosystems, using Mitsubishi Electric Iconics Digital Solutions’ OPC ToolWorX™, developed a multithreaded OPC server with redundancy features to interface with Opto22 controllers.
