The invention discloses a method for anti-falling safety protection, a controller and an elevator. The method comprises the steps that the running state of the elevator is obtained; under the condition that the operation state of the elevator is accelerated operation, the estimated operation distance and the actual operation distance of the elevator are obtained; determining a difference value between the estimated running distance and the actual running distance to obtain a sliding distance; judging whether the sliding distance is greater than a preset distance; and when it is judged that the car sliding distance is larger than the preset distance, a hovering instruction is sent to the frequency converter to control the motor to hover. According to the method, the probability that the elevator is in danger when falling abnormally can be reduced by judging the sliding distance in the whole working process of the elevator in real time.

    本申请公开了一种用于防坠安全保护的方法、控制器及升降机。该方法包括:获取升降机的运行状态;在升降机的运行状态为加速运行的情况下,获取升降机的预估运行距离和实际运行距离;确定预估运行距离和实际运行距离的差值,以得到溜车距离;判断溜车距离是否大于预设距离;在判定溜车距离大于预设距离的情况下,发送悬停指令至变频器,以控制电机悬停。本申请能通过对升降机在工作全过程中对溜车距离的实时判断,降低升降机在异常下坠时发生危险的概率。
