Wind Turbine Listening Device Ready for Commercialisation
Australian start-up Ping Services has raised almost 533,000 euros in funding to commercialise the Ping Monitor. The patented device uses acoustic analysis, machine learning and the Internet of Things (IoT) to continuously detect wind turbine blade damage.
The key piece of technology is the algorithm that can rate the health of the turbine based on its acoustic signature and monitor changes over time. The device easily attaches to wind turbine towers and actively listens to the blades’ acoustic signature while rotating to detect blade faults such as pitting or cracks caused by lightning strikes or hail.
Low Orbit Nanosatellite Technology
Its conical shape protects its microphone from rain, debris such as bird droppings and ground level noise. Data collected is transferred from remote sites via low orbit nanosatellite technology.
The second-generation Ping Monitor 2.0 will be launched next month. The Ping Monitor intelligent listening system is also being applied to asset monitoring in the mining, transport and power sectors.
