The invention relates to a tower crane rotation process state control method. According to the method, a pose sensing device is adopted to obtain pose change data of the top end of a tower crane in the rotation process of the tower crane, and when the pose change exceeds a set safety threshold range, a system can give an alarm for reminding, and meanwhile, an intelligent control strategy is automatically started to obtain the vibration direction of the tower crane; and a reverse driving force opposite to the vibration direction of the tower crane can be applied by the system to the tower crane by controlling an electrical system of the tower crane and modifying relevant parameters of a frequency converter for controlling rotation actions, so that the vibration direction of the tower crane is opposite to the acceleration direction of the tower crane along an X axis or a Y axis, the vibration condition of the top end of the tower crane is inhibited, and stable operation of the tower crane is ensured.

    本发明涉及一种塔机回转进程状态控制方法,该方法采用位姿感知装置获取塔机在回转过程中获取塔机顶端的位姿变化数据,当位姿变化超出所设定的安全阈值范围时,系统将会发出报警提醒,同时自动开启智能控制策略,获取塔机振动方向,系统可以通过控制塔机电气系统,修改变频器控制回转动作的相关参数,为塔机施加一与塔机振动方向相反的反向驱动力,使塔机振动方向与塔机加速度方向在沿X轴或Y轴相反,以达到抑制塔机顶端振动情况,保障塔机稳定运行。
