The invention provides a crane lifting control method and system and a crane. According to the method, human participation is not needed, automation can be achieved, the automation degree of crane lifting control is improved, interference of human factors on the control process can be avoided, and the control accuracy can be improved. Moreover, when one working winch is available, a specific control strategy is given, and through initial difference information between the initial working lifting hook height and the target lifting height, the automatic lifting control precision of the crane can be improved, and it is ensured that the real-time working lifting hook height can accurately reach the target lifting height.

    本发明提供一种起重机起升控制方法、系统及起重机,该方法并不需要人为参与,可以自动化实现,不仅提高了起重机起升控制的自动化程度,还可以避免人为因素对控制过程的干扰,提高控制准确度。而且,在工作卷扬的数量为一个时给出了具体控制策略,通过初始工作吊钩高度与目标起升高度之间的初始差异信息,可以提高起重机起升的自动控制精度,确保实时工作吊钩高度能精确达到目标起升高度。
