1Reliability
If traditional audio monitoring systems are used for space systems, then the system structure is simple, but the capability to identify and predict impending anomalies in real-time is insufficient
Solution Approach 1:
The patent replaces traditional mechanical audio monitoring systems with an intelligent system based on neural networks and machine learning algorithms. The IAAA uses deep learning models including auto-encoders, recurrent neural networks, and convolutional neural networks to process audio and vibration data, substituting conventional signal processing methods with advanced computational intelligence to achieve superior anomaly detection capability
Solution Approach 2:
The patent introduces an intelligent processor module as an intermediary between the audio input array and the output system. This module contains neural network algorithms that act as mediators to analyze temporal dynamics in audio data, bridge the gap between raw sensor signals and actionable anomaly predictions, and enable real-time decision-making without requiring complex human intervention
2Measurement precision
If advanced neural network algorithms are deployed for real-time anomaly prediction, then anomaly detection accuracy is improved, but computational resource consumption increases
Solution Approach 1:
The patent segments the neural network processing into distinct functional modules: an intelligent processor module for real-time inference containing optimized neural network algorithms, and a separate training phase that can be performed offline. The audio processing is divided into feature extraction, temporal dynamics analysis, and anomaly classification stages, allowing computational resources to be allocated efficiently and reducing real-time energy consumption while maintaining high detection accuracy
Solution Approach 2:
The patent employs parameter optimization techniques to adjust neural network hyperparameters, activation functions, and network architecture to achieve the best balance between accuracy and computational efficiency. The system dynamically adapts processing parameters based on the specific anomaly detection task, reducing unnecessary computational operations while maintaining high detection precision
3Reliability
If comprehensive temporal dynamics analysis is performed on audio data, then anomaly prediction capability is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary feature extraction and data preprocessing on audio signals before they are fed into the neural network for anomaly detection. The system pre-processes audio data to extract relevant temporal dynamics features, pre-trains neural network models offline, and prepares classification thresholds in advance, significantly reducing the processing time required during real-time operation while maintaining comprehensive analysis capability
Solution Approach 2:
The patent implements continuous monitoring and processing of audio data streams without interruption. The neural network processes audio inputs in real-time as they arrive, maintaining a continuous analysis pipeline that processes temporal dynamics continuously rather than in batch mode. This ensures timely anomaly detection while optimizing processing throughput to minimize latency
