Abstract: A set of aerospace sealed relay signal detection method is designed based on the Particle Impact Noise Detection(PIND) method and several representative features are selected by analyzing the time domain and frequency domain of the signal.By applying the machine learning method and using multi-layer perceptron as well as super-parameter optimization,the optimal hyper-parameter combination is found.The signal is processed and analyzed to determine if there is any excess in the sealed relay.The accuracy of the classification is improved,and the overall performance of the model is also improved.
