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.

    本发明公开了一种电动修井机天车防碰控制方法、系统、设备及介质,基于驱动电机转速n1和变速箱速比i,计算得到滚筒转速n2,基于滚筒转速n2,计算滚筒上钢丝绳缠绕的圈数r;基于滚筒上钢丝绳缠绕的圈数r、滚筒半径R1,钢丝绳半径R2和滚筒每层可缠绕钢丝绳圈数r0,计算大钩提升高度lt,将大钩提升高度lt与预设的安全限制值进行比较,得到相应的比较结果,基于比较结果,输出相应的控制信号进行制动控制。
