The invention provides a train wheel diameter correction method and device, electronic equipment and a medium. The method comprises the following steps: determining a first train speed based on the resolution of a speed sensor, a preset wheel diameter value and the number of pulses output in unit time; determining a second train speed based on the included angle error between the installation position of the radar speed measurement sensor and the horizontal plane, the included angle error between the installation position and the longitudinal axial plane where the train advances, and the included angle between the direction of transmitting electromagnetic waves and the horizontal plane; determining the acceleration of the train based on the acceleration measurement value of the train, the included angle error between the installation position of the accelerometer and the horizontal projection of the train acceleration direction, the included angle error between the installation position and the longitudinal projection of the train acceleration direction, the inherent error and the measurement noise; determining a target wheel diameter value based on the first train speed, the second train speed and the train acceleration; and correcting the preset wheel diameter value based on the target wheel diameter value. According to the train wheel diameter correction method, it can be guaranteed that the train wheel diameter correction result is more accurate.
