| titleOfInvention | Integrated Acousitic Leak Detection Apparatus and Method Using a Beamforming System |
| abstract | The present invention relates to a system that maps absolute sonic noise intensities to three-dimensional sonic noise regions and uses three-dimensional absolute noise intensities to infer operating or performance characteristics of the part or structure within the monitored region. The local noise source is extracted using the transducers of the remote array and the absolute intensity can be measured even if it is totally shielded by background noise at the transducer position. The system includes an integrated sensor device, a neural network detection system algorithm, a zoom system for accurately inspecting small areas within a steam generator vessel, a fuzzy logic system detection algorithm, and an expert detection system. Signal processing subsystems operate at three different levels of detection. Neural network systems trained at the highest level of detection monitor the length of the vessel to indicate leakage. The proposed approach uses a classifier that does not require beam shaping of the sensor signal. The presence of the leak and its general location in the container is determined using a fuzzy field expert system. The indication of the leak goes to the second level of detection; A beam-forming system that monitors the marking portion of the vessel. The third level of detection systematically monitors tagged locations to determine the actual presence of a leak for a particular location in order to accurately detect leaks above a defined threshold. The action taken is controlled by a second fuzzy logic expert interface controller. |
