The invention discloses an elevator car passenger abnormal behavior identification method and device, and the method comprises the steps: S1, collecting a vibration acceleration signal through a control variable method with the passenger abnormal behavior type as a variable, calculating a peak value and a kurtosis value, and constructing an evaluation set; s2, constructing a second membership function by using an expert scoring method in combination with the evaluation set, obtaining corresponding experimental probability distribution results when different passenger abnormal behaviors occur, and constructing an abnormality judgment function used for calculating real-time probability distribution corresponding to the passenger abnormal behaviors; s3, collecting a real-time vibration acceleration signal, constructing a real-time signal evaluation set, judging the type of the abnormal behavior of the passenger by using an abnormality judgment function and an experimental probability distribution result, and identifying an abnormality level according to a peak value; and S4, giving an alarm prompt according to the abnormal behavior type and the abnormal level of the passenger. The elevator operation can be monitored, the abnormal behaviors of passengers are recognized, and manual abnormal vibration of the elevator is effectively reduced.
