Collision prevention method and device and computer-readable storage medium

The invention discloses a collision prevention method and device and a computer-readable storage medium. The distance between two mechanical shafts and the actual motion status of the two mechanical shafts can be determined by monitoring the position and motion parameters of the first and second mechanical shafts sharing the same rail, according to the corresponding relationship between the presetminimum safety distance and the state of the motion, the minimum safety distance corresponding to the actual motion status of the two mechanical shafts is determined and used as the target safety distance, and the fact that when one mechanical shaft suddenly stops, the other mechanical shaft cannot collide with the stopped mechanical shaft can be ensured by the minimum safety distance. Accordingto the collision prevention method, when the difference between the distance between the two mechanical shafts and the target safety distance is not in the preset range, the motion parameters of at least one shaft of the two m
