The invention relates to a train speed detection method and device, electronic equipment and a medium, and belongs to the technical field of rail transit, the method comprises the following steps: obtaining target vibration data of each measuring point collected by a fiber grating array vibration sensing network in real time, the measuring points being arranged along a train rail; determining initial energy data of each measuring point based on the target vibration data of each measuring point; extracting target energy data of each measuring point with an energy value higher than a threshold value from the initial energy data of each measuring point; determining a time difference of the target energy data of each measuring point based on the target energy data of each measuring point; and calculating the train speed based on the time difference and the distance between the measuring points. The rail train speed is detected through the anti-electromagnetic interference fiber grating array vibration sensing network, and the problem that the train speed is not accurately calculated due to the fact that a train control system in current rail transit is prone to electromagnetic interference is solved.
