Method for predicting storage life of electromagnetic relay

The invention discloses a method for predicting the storage life of an electromagnetic relay. The method comprises the following steps: step 1, acquiring a certain degradation performance parameter of the electromagnetic relay; 2, preprocessing the degradation performance parameters to form a data set; step 3, obtaining an optimal weight and an optimal threshold in the data set through a snake optimization algorithm; 4, an ELM neural network is constructed, the ELM neural network is trained through the data set, and the input of the ELM neural network is actual degradation performance parameters; outputting a prediction degradation performance parameter, and taking the optimal weight and the optimal threshold obtained in the step 3 as the optimal weight and the optimal threshold of the ELM neural network; and step 5, the actual degradation performance parameters pass through the trained ELM neural network to obtain predicted degradation performance parameters, and life prediction is completed.
