The invention provides a lifting appliance zero position detection method, a lifting appliance zero position detection device and a crane, and solves the technical problem that in the prior art, due to the fact that a sensor is influenced by external temperature, a direct output value of the sensor has a temperature drift phenomenon, and zero position measurement of a lifting appliance is not accurate. According to the zero detection method for the lifting appliance, after the tilt angle sensor directly measures the output tilt angle data, online temperature drift compensation is carried out on the output tilt angle data, and the problem that zero measurement of the lifting appliance is not accurate due to the temperature drift phenomenon of the direct output value of the sensor caused by the influence of the external temperature is solved; in addition, the zero value of the lifting appliance at any position can be calculated in real time, and the accuracy and consistency of zero measurement are improved.

    本申请提供了一种吊具零位检测方法及其装置、起重机,解决了现有技术中现有技术中传感器受外界温度影响导致其直接输出值发生温漂现象,进一步引起吊具零位测量失准的技术问题。本申请提供的一种吊具零位检测方法,当倾角传感器直接测量输出倾角数据后,然后对输出倾角数据进行在线温漂补偿,克服了传感器受外界温度影响导致其直接输出值发生温漂现象,进一步引起吊具零位测量失准的问题;另外,可以实时计算吊具在任意位置处的零位值,提高了零位测量的准确性和一致性。
