Application of the InfraWatch Technology
During a recent renovation project, a total of 145 sensors were embedded in and attached to the Hollandse Brug by Strukton. These sensors include strain sensors, vibration sensors, temperature sensors, and also a video camera. This large array of sensors continuously monitor all events on the bridge, and provides a huge data flood from it: every day, about 5 GB of non-video data is gathered, more than one DVD a day!
Having all this data is a good start, but making sense of all this data is even better. In order to get a better understanding of how the bridge behaves over time, we need to store data over a very long time span, and use this to find interesting changes and behaviours. This is the real challenge, as current data analysis techniques often operate on data that is just a fraction of this size.
