The invention belongs to the technical field of elevators, and discloses an elevator operation abnormal state analysis method which comprises the following steps: collecting signals in an elevator operation process through a sensor; performing time domain and frequency domain analysis on the signals, and extracting signal features; performing principal component analysis on the signal features; inputting the signal features into a BP neural network for learning and training, wherein the BP neural network is optimized through an improved whale optimization algorithm; and elevator signals collected in real time and the extracted signal features are input into the trained BP neural network, and the BP neural network outputs an elevator operation abnormal state analysis result. According to the method, the BP neural network is optimized through the improved white whale optimization algorithm, the optimized BP neural network has high learning ability, the abnormal state of elevator operation can be analyzed from the elevator operation data, and therefore the elevator is maintained.
