The invention provides a low-position control method and system for a full-automatic control bridge crane, and relates to the technical field of automation, the method comprises the following steps: S1, receiving steel coil data, and calculating a predetermined descending height; s2, descending the steel coil; s3, the steel coil is suspended when descending to a preset height; s4, the steel coil swing angle is judged according to the hovering time, and the steel coil re-starting coil falling moment is calculated; s5, steel coil descending is started; and S6, when the swing angle is equal to 0, the steel coil falls to the ground. According to the invention, the precision of the drop point of the hoisted object of the full-automatic control bridge/portal crane can be improved, and the production requirements are met.

    本发明提供一种全自动控制桥式起重机的低位控制方法及系统,涉及自动化技术领域,该方法包括:步骤S1:接收钢卷数据,计算预定下降高度;步骤S2:下降钢卷;步骤S3:下降钢卷到预定高度时悬停;步骤S4:利用悬停时间判断钢卷摆动角度,计算钢卷再次启动落卷时刻;步骤S5:启动钢卷下降;步骤S6:在摆动角度等于0时使钢卷落地。本发明能够提高全自动控制桥式/门式起重机的吊物落点精度,满足生产要求。
