Abstract EN
This work describes a network of low power/low-cost microelectromechanical- (MEMS-) based three-axial acceleration sensors with local data processing and data-to-cloud capabilities.
In particular, the developed sensor nodes are capable to acquire acceleration time series and extract their frequency spectrum peaks, which are autonomously sent through an ad hoc developed gateway device to an online database using a dedicated transfer protocol.
The developed network minimizes the power consumption to monitor remotely and in real time the acceleration spectra peaks at each sensor node.
An experimental setup in which a network of 5 sensor nodes is used to monitor a simply supported steel beam in free vibration conditions is considered to test the performance of the implemented circuitry.
The total weight and energy consumption of the entire network are, respectively, less than 50 g and 300 mW in continuous monitoring conditions.
Results show a very good agreement between the measured natural vibration frequencies of the beam and the theoretical values estimated according to the classical closed formula.
As such, the proposed monitoring network can be considered ideal for the SHM of civil structures like long-span bridges.
