The invention discloses a method and system for protecting a lifting device, a driving device and a storage medium. The method comprises the following steps: receiving a pulse feedback value sent by a lifting device; determining a working voltage and a voltage interval where the working voltage is located; under the condition that the working voltage is in the first voltage interval, determining a pulse threshold according to a preset curve; judging whether the pulse feedback value is greater than or equal to a pulse threshold; and when the pulse feedback value is judged to be greater than or equal to the pulse threshold value, starting a zero servo function. Under the condition that the working voltage is in the first voltage interval, the pulse threshold value is determined according to the preset curve, the possibility that the load falls can be reduced, and the safety of the lifting device and the load is improved.
本申请公开了一种用于保护提升装置的方法、系统、驱动装置及存储介质。该方法包括:接收提升装置发送的脉冲反馈值;确定工作电压以及工作电压所处的电压区间;在工作电压处于第一电压区间的情况下,根据预置曲线确定脉冲阈值;判断脉冲反馈值是否大于或等于脉冲阈值;在判定脉冲反馈值大于或等于脉冲阈值的情况下,启动零伺服功能。本申请在工作电压处于第一电压区间的情况下,根据预置曲线确定脉冲阈值,能够降低负载坠落的可能,提高提升装置及负载的安全性。
