摘要
桥式起重机工作在大载荷,大冲击场合,钢丝绳张力传感器测量吊重载荷瞬时冲击效应明显,吊重载荷测量波动大,给控制系统、故障诊断、安全作业提示带来了过多干扰数据。通过分析当前旁压式传感器的测量原理,将其应用到容积卡尔曼数字滤波中,实现了过滤冲击效应带来的瞬时波峰,提升了桥式起重机控制系统的安全性。
On the occasion of bridge crane bearing heavy workload and shock, the steel wire tension sensor indicates an obvious effect of instantaneous shock of lifting load. The fluctuation of lifting load measurement brings about overmuch interference data to the control system, fault diagnosis and safe operation tips. By analyzing the measurement principle of current bypass pressure sensor, applied to the volumetric Kalman Digital Filter, instantaneous wave crest caused by filter shock effect is realized, which improves the safety of bridge crane control system.
