The invention discloses an electric workover rig crown block anti-collision control method, system and device and a medium. Based on the rotating speed n1 of a driving motor and the speed ratio i of a gearbox, the rotating speed n2 of a roller is calculated, and based on the rotating speed n2 of the roller, the number r of turns of winding of a steel wire rope on the roller is calculated; the method comprises the steps of calculating the lifting height lt of a large hook based on the number r of turns of a steel wire rope wound on a roller, the radius R1 of the roller, the radius R2 of the steel wire rope and the number r0 of turns of the steel wire rope capable of being wound on each layer of the roller, comparing the lifting height lt of the large hook with a preset safety limit value to obtain a corresponding comparison result, and outputting a corresponding control signal for brake control based on the comparison result.
