On the 15th of December, the 2nd Italian Pilot took place, at our AMT partner’s historical depot & car park complex, based in Catania – in the Sicily Region.

The Pilot focus was monitoring infrastructures and buildings of heritage value by using IoT sensors. A total of six sensor units have been deployed in the historical building to be monitored.

We used two different types of sensors.The first one is composed by two programmable sensors based on Raspberry technology and internally designed and realized by ALMAVIVA. They are equipped with accelerometers, gyroscopes and thermometer modules. The remaining 4 sensors were commercial BLE (Bluetooth Low Energy) beacon 3-axis accelerometer units. An additional BLE gateway was used to collect all the beacon sensors data and forward them to the three SCENE IGWs available, two of them installed in buses and the third one inside the building.

Due to the COVID-19 pandemic restrictions, only AMT staff participated in presence to the pilot. The other Consortium partners attended the pilot in a MS Teams virtual room, set up for all the duration of the pilot.

First, a stress test was executed to measure the central Service Platform performance level in processing high volumes of data. By configuring the raspberry sensors to fire data at a high frequency – one message each 100 milliseconds – we were able to increase the traffic load towards the Service Platform.After this first test, the pilot continued with a more standard traffic level for the whole day, with the raspberry sensors generating IoT measures each 250 milliseconds.

In addition, during the Catania Pilot, the Content Delivery System has also been tested inside a bus, with the aim to test content prefetching and caching in secure communication channels.

Despite the pandemic emergency, the Consortium has successfully deployed this complex test environment to validate the final prototype of the SCENE Platform. More than one million of different IoT sensor measures have been received, processed, and registered in the SCENE data lake during all the Pilot.All data hasbeen analyzed by the consortium team.

The pilot showed how the SCENE Platform final release is worth able. In fact, it can be used to monitor critical infrastructures – such as cultural heritage, historical buildings, or other infrastructures -even in sensitive areas due to their morphological nature. Catania is in fact, a seismic area due to the presence of the highly active Etna volcano.

Scene Platform dashboard allows to carry out appropriate maintenance interventions on the asset under monitoring avoiding any damage. It is indeed a valuable analysis tool!
