PROJECTS - Application Notes


High Fidelity Ground Truthing of Smart Sensor Signals

The RESONATE SYSTEMS developed DATAFLEX monitoring solutions was implemented and tailored to support SA Water’s Smart Network development.
At the core of the solution, the field remote data acquisition system FLEXDAQ provides sample accurate time synchronisation across distributed systems, regardless of their location.
FLEXDAQ systems acquire signals from multiple sensor types and this information is used to provide a “Ground Truth Reference” to support the wide scale deployment of smart IoT sensors across the Adelaide metropolitan network.
The tight temporal correlation provided by the systems allowed SA Water internal analytics capability  and academic partner to advance their understanding of the physical mechanism behind pipe leak acoustic signatures.

Both raw waveforms and processed metrics are stored locally. Alert limits can also be set by end-users with SMS messaging direct from the FLEXDAQ unit to nominated stakeholders. Edge device processed metric values (1 Hz) are automatically uploaded to the FLEXSPACE cloud service in batches every 2 - 3 Minutes. Distributed Systems Time Synchronisation To identify critical events occuring within the water distribution network, FLEXDAQ systems provide accurate time synchronisation of > 10 Nanosecond
