The invention discloses a tower crane anti-swing control method based on a movement compensation technology. The tower crane anti-swing control method comprises the following steps: step 1, acquiring swing angle data of a crane hook and length data of a steel wire rope and transmitting the data to a data processing module in real time; 2, the data processing module monitors the swing angle of the crane hook, and when the swing angle exceeds a set swing angle threshold value and the time from sending of the last compensation displacement instruction exceeds a time interval threshold value, compensation is triggered; 3, the data processing module calculates compensation displacement and time corresponding to the compensation displacement according to the swing angle data and the length of the steel wire rope, converts the compensation displacement and the compensation time into a compensation displacement instruction, and sends the compensation displacement instruction to the frequency converter; and step 4, the frequency converter drives the variable-amplitude trolley to perform compensation at the operation frequency corresponding to the compensation displacement instruction.
本发明公开了一种基于移动补偿技术的塔式起重机防摇摆控制方法,步骤包括:步骤1、获取起重机吊钩的摆角数据以及钢丝绳长度数据实时传递给数据处理模块;步骤2、数据处理模块监测起重机吊钩的摆角大小,当摆角大小超过设定的摆角阈值时并且离上一次补偿位移指令发送的时间超过时间间隔阈值时触发补偿;步骤3、数据处理模块通过摆角数据和钢丝绳长度计算补偿位移以及补偿位移对应的时间,将补偿位移以及补偿时间转换为补偿位移指令,将补偿位移指令发送至变频器;步骤4、变频器以补偿位移指令对应的运行频率驱动变幅小车进行补偿。
