The invention provides a subway wheel rail damage online detection method, device and system. The method comprises the steps that a vibration acceleration signal of a subway wheel rail is collected through a vibration acceleration sensor; preprocessing the vibration acceleration signal to obtain a longitudinal vibration acceleration signal; carrying out integral processing on the longitudinal vibration acceleration signal according to a preset frequency range to obtain a displacement amount generated by the wheel in a preset time period; carrying out segmented superposition on the displacement according to a preset wheel perimeter to obtain a target wheel abrasion loss; and subtracting the target wheel abrasion loss from the displacement amount to obtain the target track abrasion loss, and completing online detection of the subway wheel track damage. The vibration acceleration sensors are installed on the wheel sets of the running vehicle, online detection of the wheel sets and the track can be achieved, abnormal abrasion of the wheel sets and the track is recognized by analyzing the vibration acceleration signals collected by the vibration acceleration sensors, and the pertinence and efficiency of wheel track detection are improved.
