AI Technical Summary
Existing leak location methods are unstable and difficult to verify and achieve high-precision location under conditions of multipath noise and array geometric errors. In particular, they are difficult to generate reliable alarms in complex pipe section scenarios, which affects the implementation of closed-loop fault prediction and health management.
By extracting multipath propagation characteristics and determining propagation compensation parameters to correct infrasound signals, and combining array geometry parameter updates and azimuth filter noise parameter updates, the correction and fusion of multi-channel infrasound signals are achieved, and the refined wave arrival azimuth is output. Finally, the leak location is determined by combining pipeline geographic information.
It achieves high-precision leak location under multipath noise and array geometric error conditions, provides verifiable leak location results, and provides traceable and verifiable spatial location basis for fault prediction and health management, reducing the instability and error of the location results.
