The invention discloses an electric energy meter automatic verification assembly line meter position operation state evaluation method and system, and the method comprises the steps: obtaining the historical test data of a meter position on a verification assembly line in different operation states, carrying out the batch effect removal of the historical test data based on the normal meter position data, and carrying out the calculation of the normal meter position data; feature vectors of all the epitopes in different operation states are constructed; constructing a twin neural network, updating network parameters by setting a boundary value when the twin neural network is trained based on the feature vector of each epitope, and constructing a state evaluation model by introducing a state judgment threshold; carrying out parameter optimization on the state evaluation model by adopting a Wild-gull optimization algorithm and taking the model evaluation reliability as a fitness function to obtain an optimized s
