In addition to internal sensors, the node can be connected to external sensors such as strain gauges, LVDTs, load cells, etc. The acquisition device not only reads the signal but is programmed to select and clean the data to be transmitted, greatly reducing the influx of data.
The MonStr system is fully integrated with the Opensource OpenSees computing program and artificial intelligence algorithms through the use of the STKO software. The artificial intelligence algorithms allow for Optimal Sensor Placement (OSP) and model calibration. They also interpret the damage and emit alarm signals that are then checked against the finite element model to assess whether the signal is a false positive. This reduces the number of false positives, especially during the first years of use when the data pool acquired is not sufficient for reliable interpretation using artificial intelligence.
