The embodiment of the invention provides an elevator state detection method and device, equipment and a storage medium, and the method comprises the steps that an obtained nearest acceleration sequence is subjected to frequency domain transformation to obtain a target frequency spectrum, and the target frequency spectrum is converted into a power spectrum; then, under the condition that the power value corresponding to the power spectrum jumps from the first power area to the second power area, recording of the real-time acceleration value is started, recording is stopped until the real-time acceleration value is within a preset critical range, a target acceleration sequence is obtained, the target acceleration sequence is compared with a set state template sequence, and the state template sequence is obtained; the vertical movement state of the elevator is determined; and finally, carrying out difference value calculation on elements in the obtained nearest air pressure sequence and a reference air pressure value to obtain an air pressure difference value sequence, inputting the air pressure difference value sequence into the trained neural network model to obtain a prediction result, and determining the elevator floor position based on the prediction result. According to the scheme, the accuracy of elevator state detection is effectively improved, and reliable state data reference is provided.
