Airborne Imaging and Acoustic Detection Solution
Enables high-altitude flight-based inspections, suitable for remote live-line inspections and fault location of overhead transmission and distribution lines as well as outdoor substation equipment; proactive predictive maintenance inspections of power equipment such as railway lines; and application scenarios including petrochemicals, forest fire prevention, emergency rescue, industry, and inspection services. It provides a new paradigm of safe, efficient, and intelligent aerial inspections for industries such as power, petrochemicals, and new energy.
Scheme Overview
The R3 and R4 airborne acoustic imaging systems are acoustic detection devices that integrate sound source localization and ultrasonic imaging technologies. They are compatible with DJI drones and feature a dual-layer noise-reduction design—combining a noise-resistant algorithm inspired by drone rotor simulations with a specially engineered noise-resistant structure—to ensure excellent anti-interference performance and stability. These systems effectively suppress drone-generated noise interference, enabling the detection of even the tiniest signals. Operating in the frequency range of 1 kHz to 100 kHz, they deliver real-time imaging at 25 frames per second, with a positioning accuracy of ≤1 cm. This allows for truly “zero-altitude, zero-power outage, and zero-contact” inspection of leaks and partial discharges during comprehensive surveys.
Scheme Comparison
Ground-based remote control, with aerial scanning to cover blind spots such as tower tops and cable clamps, enabling “zero-altitude” operations.
Manual inspections require lift trucks or climbing iron towers, which are physically demanding and carry a high risk of falls from heights.
Operates under live conditions, enabling comprehensive inspections without needing to change the equipment’s status, thereby reducing outage time to zero.
The detection environment is complex and easily affected by factors such as ambient temperature, which limits its applicability.
30-second imaging, 10-minute completion—each flight covers the entire line, enabling rapid inspection.
Relying on individual maintenance experience often requires repeated, point-by-point inspections, which is inefficient and prone to missed detections.
The airborne acoustic imaging device focuses on the ultrasonic frequency band, leaving no trace of even the tiniest leaks.
Microscopic partial discharges are difficult to detect (with no heating), the detection results are not intuitive, and it’s inconvenient to record them.
