A wind farm in northwest China's Ningxia Hui Autonomous Region has employed AI-powered industrial acoustic sensors to help with wind turbine maintenance, improving efficiency and reducing risk.
The Huadian Ningxia Ningdong Wind Farm in Gobi Desert, with 212 turbines, introduced industrial acoustic sensor, a palm-sized device equipped on turbine's blades. Thanks to the new assistance, high-frequency signals inaudible to the human ear can be captured, such as early-stage micro-cracks and abnormal friction in the equipment.
If abnormal sounds are detected, the intelligent system driven by large acoustic models enables in-depth analysis of massive amounts of voiceprint data using artificial intelligence, so as to accurately locating which part of which blade is abnormal and triggering immediate alerts to the control room.
This greatly reduced manual jobs in the past when technicians used binoculars and drones to observe blade rotation trajectories from the ground before climbing to the nacelle, performing detailed troubleshooting, and carrying out repairs.
The new approach not only saved long hours of labor but also protected the technicians from significant safety risks.
As part of its push toward a fully smart, unattended wind farm, the acoustic intelligence has been set up across the site. Transformers and other key equipment now feature similar sound-based monitoring, while humanoid and wheeled robots handle routine patrols.
The new mode of maintenance is expected to reduce annual inspection time at station by about 3,000 hours, cut labor costs by about 60 percent, and enable unmanned monitoring of core equipment around the clock.

Nicaragua's co-foreign minister Valdrack Jaentschke has warned that militarism must never be allowed to rise again, as Japan's recent moves to lift its arms export ban and revise the pacifist Constitution continue to draw international concern.
This year marks the 80th anniversary of the opening of the Tokyo Trials, where Japan's Class-A war criminals from World War II were brought to justice.
In an interview with China Global Television Network (CGTN), Valdrack Jaentschke voiced his concern that today's world order is being undermined by interventionism and other challenges.
"It is necessary for us to remember that after the end of World War II, countries worked hard to build a new international order based on international law. However, regrettably, more than 80 years later, we are seeing that this once explored and attempted order is being challenged by interventionism, a confrontational mindset, and tendencies like 'might makes right.' These are precisely the conditions that gave rise to fascism and militarism in the past, which ultimately led to the tragedy of World War II," he said.
He said the international community has a responsibility to pursue a new international order -- one fundamentally grounded in peace.
"Looking back at the history more than eight decades ago and comparing it with today's reality, it is our responsibility to recognize that the world should, and must, build a new international order that is more just, fairer, rooted in international law, based on a logic of mutual benefit and shared success, and fundamentally grounded in peace," said the minister.
"Today, as we revisit the Tokyo Trials, it is meant to remind the world that such a tragedy must never be repeated -- and that we must do everything in our power to prevent it from happening again. We must stop that dark world -- born from militarism, interventionism, and fascism -- from ever returning," he said.
