The invention provides a train running direction detection method, device and equipment and a storage medium, and belongs to the technical field of rail transit train detection.The method comprises the steps that detection area vibration data of a train in all detection areas in a preset time window are obtained based on a grating array vibration sensing network; determining a maximum cross-correlation value between a current measurement area and an adjacent measurement area adjacent to the current measurement area based on the measurement area vibration data, and determining a time difference between data pairs corresponding to the maximum cross-correlation value; obtaining a position difference between the current measurement area and the adjacent measurement area; and the running speed of the train and the positive and negative values of the running speed are determined based on the position difference and the time difference, and the running direction of the train is determined based on the positive and negative values. According to the invention, accurate detection of the running direction of the train is realized.
