The invention provides a method for measuring lifting precision, which comprises a lifting arm, a winch, a steel wire rope, an AHC control system and an attitude motion measurement sensor, the AHC control system further comprises a CDP system and an encoder, the displacement of the steel wire rope is detected through the AHC control system, the displacement of a load is detected through the attitude motion measurement sensor, and the displacement of the load is measured through the CDP system. And then the displacement of the steel wire rope is compared with the displacement of the load to judge whether the displacement is within an error range or not, so that the lifting height of the crane is accurately verified.
本发明提供一种测量起吊精度的方法,包括吊臂、绞车、钢丝绳、AHC控制系统、姿态运动测量传感器,AHC控制系统还包括CDP系统和编码器,通过AHC控制系统对钢丝绳位移量进行检测,通过姿态运动测量传感器对负载位移量进行检测,然后将钢丝绳位移量与负载位移量进行对比,判断其是否落在误差范围内,从而对起重机的起升高度进行精准验证。
