The invention discloses an elevator car anomaly detection method and system for electric vehicle recognition, and the method specifically comprises the following steps: a special training data set isconstructed for an electric motor car, an electric vehicle picture is downloaded on a Baidu search engine, the position of the electric vehicle in the training set is marked through an image marking tool, the data is used as a label of training data; in the model training step, based on the electric vehicle training data set in the first step, 1000 rounds of iterative optimization are carried out,and the accuracy of the electric vehicle recognition model is improved. A self-built electric vehicle data set is used for training a neural network model, the recognition precision for the electricvehicle is improved, the safety of a lift car is guaranteed, and the risk of safety accidents in the later period is reduced; by constructing a special electric vehicle data set, the electric vehiclerecognition and detection precision is improved; an edge computing mode is adopted, and a microcontroller is utilized to solve the problem of time delay depending on a cloud network and even the problem of electric vehicle detection and recognition with an unavailable network.
