The invention relates to the technical field of elevator operation and maintenance, and particularly provides a method and system for recognizing elevator faults through an acceleration sensor, and the method comprises the steps that the acceleration sensor is adopted to obtain acceleration data of x, y and z three freedom degrees of an elevator; decomposing data of the acceleration sensor into uplink and downlink state data and static door opening and closing state data; the ascending and descending operation state data and the static door opening and closing state data of the elevator are preprocessed, and data of a training set under the ascending and descending operation state of the elevator and data of a training set under the static state of the elevator are obtained; deep learning training is conducted on the training sets of the two stages of elevator ascending and descending and elevator static through an LSTM model, and parameter models corresponding to the two stages are obtained; and elevator acceleration sensor data to be processed are input into the two models respectively for fault recognition. According to the invention, the elevator fault is analyzed by using the data of the acceleration sensor, so that the elevator fault analysis is more accurate and higher in efficiency.
