The invention relates to a railway vehicle anti-collision system and method on the basis of absolute displacement, and solves the problems in the existing technology that anti-collision control is not accurate enough and anti-collision hazards exist. The system comprises at least two railway vehicles running on the same rail, each railway vehicle is provided with a speed displacement information acquisition unit, a network connection unit, a position state detection unit, a variation trend relation judgment unit, a front and back position relation judgment unit, a running status analysis unit and an anti-collision strategy output unit. Through the detection of the front and back position relation between the railway vehicles and the variation trend relation of absolute displacement values of the railway vehicles, the movement relation between the two railway vehicles is judged, the current limiting speed is calculated, and compared with the current speed, whether the anti-collision control is output or not is judged. The railway vehicle anti-collision system and method on the basis of the absolute displacement have the advantages that the running status of the railway vehicles can be analyzed and judged through the absolute displacement values, the relations of distance and movement between the railway vehicles are accurately analyzed, accurate data are provided for the anti-collision calculation, and the anti-collision control accuracy is improved.
