AI Technical Summary
Existing technologies are insufficient for non-contact, long-distance leak detection of steel wire-wound reinforced polyethylene composite pipes in complex industrial environments, and their accuracy and adaptability are inadequate.
Non-contact scanning is performed using an acoustic imager, and an acoustic image is generated by combining a beamforming algorithm. Acoustic signals are captured by a microphone array and environmental noise is suppressed. Leakage points are evaluated by analyzing the dominant frequency characteristics, and a model of the correspondence between the leakage aperture and the dominant frequency characteristics is established.
It enables precise visualization and accurate location and assessment of leak points, improving the accuracy and adaptability of detection, and effectively identifying minute leaks in complex environments.
