The invention discloses an elevator automatic brake-releasing power supply system, an elevator and a control method.In the elevator automatic brake-releasing power supply system, a control module controls a system power supply to work when the mains supply is abnormal, and if a detection signal that a lift car is not flat is received, a star sealing removing instruction is sent to a star sealing processing module to remove star sealing; the height of the lift car and the capacity of a standby battery are obtained, the rescue speed is calculated, a brake release signal is generated according to the rescue speed and sent to a brake power source to enable the brake power source to supply power, a star sealing contactor is driven to be disconnected to release star sealing, and a brake device is driven to release brake to enable the lift car to level at the rescue speed. The rescue speed is calculated through the height of the lift car and the capacity of the standby battery, compared with car sliding leveling under the dead weight, the rescue speed is increased, the emotion of passengers waiting for rescue is relieved, the power supply duration of the standby battery is shortened, the battery capacity requirement and cost are reduced, on the one hand, manual intervention is not needed, and the cost is reduced. The method is suitable for carrying out emergency rescue in time in buildings with low occupancy rates or low-peak scenes with ladders.

    本发明公开了一种电梯自动松闸电源系统、电梯及控制方法,电梯自动松闸电源系统中,控制模块在市电异常时控制系统电源工作,若接收到轿厢未平层的检测信号,向封星处理模块发送解除封星指令解除封星,并获取轿厢的高度和备用电池的容量计算出救援速度,根据救援速度生成松闸信号发送到抱闸电源使得抱闸电源供电,驱动封星接触器断开解除封星以及驱动抱闸装置松闸使得轿厢以救援速度平层,一方面,通过轿厢高度和备用电池的容量计算救援速度,相比较于在自重下溜车平层,提高了救援速度,缓解等待救援乘客的情绪,缩短备用电池的供电时长,降低电池容量要求和成本,另一方面,无需人工干预,适用于入住率低的楼宇或用梯低峰场景及时实施紧急救援。
