The invention discloses a crane closed-loop anti-swing method for detecting a swing angle of a crane lifting rope based on an acceleration sensor, which comprises the following steps of: controlling coordinated work of each driving motor by adopting an encoder, a frequency converter and an anti-swing system, and analyzing a swing length parameter fed back by the encoder; the swing angle of a hoisted heavy object is detected through the acceleration sensor swing angle detection system, and acceleration and deceleration of the cart and the trolley are controlled in real time, so that the cart and the trolley of the crane are prevented from generating load swing in the moving process. The invention has the advantages of simple control, simple operation, small crane swing amount, small load movement swing amount, simple maintenance, low economic cost, long service life and the like.

    本发明公开一种基于加速度传感器检测起重机吊绳摇摆角的起重机闭环防摇摆方法,通过采用编码器、变频器以及防摇摆系统对各个驱动电机的协调工作控制,分析编码器反馈的摆长参数,通过加速度传感器摇摆角检测系统检测起吊重物的摇摆角度,实时地控制大车小车的加减速,从而起到防止起重机大车以及小车在运动的过程中产生负荷摇摆。本发明控制简单,操作简便,起重机摇摆量小,负载移动摆动量少,维护简单,经济成本低,使用寿命长等优点突出。
