The invention discloses a cargo boom device control method and system and a crane. The cargo boom device control method comprises the steps that the current pitching position and the current pitching speed of a cargo boom device are determined in real time; determining safe operation conditions of the cargo boom device according to the current pitching position and the current pitching speed; under the condition that it is determined that the current pitching speed meets the safe operation condition, the cargo boom device is controlled to continue to operate at the current pitching speed; according to the method, the safe operation condition of the cargo boom device is updated in real time based on the current pitching position and the current pitching speed of the cargo boom device, normal operation of the cargo boom device is maintained on the premise that safety is guaranteed, and the situation that the cargo boom device executes deceleration operation too early is avoided; and the time consumed for the crane boom device to run to the stop point is shorter, so that the working efficiency of the crane is effectively improved.
本发明公开一种起重臂装置控制方法、控制系统及起重机,起重臂装置控制方法包括:实时确定起重臂装置的当前俯仰位置和当前俯仰速度;根据当前俯仰位置和当前俯仰速度确定起重臂装置的安全运行条件;在确定当前俯仰速度满足安全运行条件的情况下,控制起重臂装置以当前俯仰速度继续运行;该方法基于起重臂装置的当前俯仰位置和当前俯仰速度对起重臂装置安全运行的条件进行实时更新,在保证安全性的前提下维持起重臂装置的正常运行,避免了起重臂装置过早地执行减速操作,起重臂装置运行至停止点所耗费的时间更短,有效提高了起重机的工作效率。
