Olympia Odos is one of the most important national motorway projects in Greece, with strategic importance for the development of the Peloponnese, Western Greece and Epirus. The motorway, a total of 201.5 km, connects the three regions and the capital of the country with the most important gate of Greece to Europe, the port of Patras.
Olympia Odos S.A. was working on a more efficient way to do the heavy maintenance of their assets and be able to monitor their conditions. They had drafted a first design of a wireless IoT sensor system, backed by cloud services that would provide big data and AI algorithms, with the ultimate goal being building a platform capable of providing predictive maintenance using all the aforementioned technologies. Ex Machina had worked previously with similar projects in Athens Airport and elsewhere, making them a great candidate for the job. Ex Machina, accepting the challenge, assembled a consortium of top notch partnering companies, ES Systems and Delphis, to address the project goals.
The project aimed to the pilot installation of an innovative tunnel equipment monitoring and maintenance system on the first tunnel of the motorway. The said system, called “Smart Tunnel”, would continuously monitor the tunnel equipment using sensors and send all data wirelessly to the cloud through “smart” data collection hubs, while populating the system with detailed maintenance data. The sensors covered a wide spectrum of the tunnel’s use cases, namely vibration analytics for jet fans, electric pumps and power generator, electric systems monitoring (batteries, UPSs) and transformer monitoring (corrosion, humidity, temperature).
Ex Machina had the platform and contributed on the systems design and, most importantly, knew the key players in order to be able to carry out this job. They were swift and capable to adapt a different approach and thanks to them, the project has been so successful.
Ex Machina designed the solution, including a custom IoT gateway and a unique network topology setup, and coordinated the installation of the sensors, ensuring their seamless connectivity and operational integrity. The data collected by Ex Machina’s IoT platform are analysed in real time, already producing valuable insights. The project was delivered in respect to the customer’s deadlines and operations.
This is a comprehensive equipment monitoring solution that uses artificial intelligence and machine learning algorithms. This solution will be gradually rolled out in all the tunnels of the motorway.
The “Smart Tunnel” aims at better planning and implementing the infrastructure maintenance campaigns, using the new tools offered by the Internet of Things. Moreover, the system will also contribute to increase the equipment lifetime, to improve the safety and the service levels, as well as to make considerable tunnel maintenance cost savings.
