The invention discloses an excavator working condition identification method and an excavator working condition identification device. The method comprises the following steps: acquiring pilot control signal data and double-pump pressure signal data of an operating handle of the excavator; preprocessing the operation handle pilot control signal data and the double-pump pressure signal data to obtain preprocessed data; constructing a feature vector according to the preprocessed data; performing feature dimension reduction on the feature vector to obtain a feature vector after dimension reduction; inputting the feature vectors after dimension reduction into a classification model to obtain a first working condition mode of the excavator; and verifying the first working condition mode and outputting a working condition identification result detail table. According to the method, the feature vector is constructed by combining the basic time domain feature of the composite signal and the actual mining situation, t
