AI Technical Summary
In complex industrial environments, existing technologies struggle to effectively monitor acoustic energy sources, especially as receivers struggle to determine the direction of noise sources due to echoes and overlapping signals from multiple sources. Furthermore, traditional beamforming algorithms are limited by static receiver arrays and cannot adapt to the self-noise interference of mobile platforms.
By employing a space-dynamic beamforming method, a receiver array is deployed on a mobile platform. Combined with beamforming algorithms and self-calibration technology, noise associated with the platform is isolated, and a high-resolution energy map is generated, enabling precise monitoring and self-health diagnosis of acoustic energy sources.
It improves the monitoring accuracy of acoustic energy sources, effectively separates foreground and background signals, provides insights into the platform's operational status, and enhances signal quality and platform health monitoring in dynamic environments.
