The invention discloses an elevator power failure emergency rescue device, a control method, an elevator and a medium. The elevator power failure emergency rescue device comprises a control module, a sampling module, an H bridge module, an emergency power supply and a voltage transformation module. When the power grid normally supplies power, the H-bridge module is controlled to work in a rectification mode to charge the emergency power supply, the problem that the emergency power supply is idle for a long time and is insufficient in electric quantity due to natural discharge is solved, and the reliability of the elevator power failure emergency rescue device is improved. The H-bridge module in an existing elevator power failure emergency rescue device is utilized to work in the rectification mode to charge the emergency power supply, an additional charging module does not need to be added, and the material cost and the maintenance cost of the elevator power failure emergency rescue device are reduced. When the elevator is powered off due to the fact that the power grid is abnormal, power is supplied to the elevator control system in time, the elevator control system drives a motor M to operate so as to enable an elevator car to operate to the closest flat layer, trapped elevator passengers are released, and the elevator riding safety is improved.

    本发明公开一种电梯停电应急救援装置、控制方法、电梯及介质,电梯停电应急救援装置包括控制模块、采样模块、H桥模块、应急电源及变压模块。在电网正常供电时,控制H桥模块工作在整流模式,以对应急电源充电,避免应急电源长期闲置因自然放电导致电量不足的问题,提高了电梯停电应急救援装置的可靠性。且利用现有的电梯停电应急救援装置中的H桥模块,让其工作在整流模式,对应急电源充电,无需增加额外的充电模块,降低了电梯停电应急救援装置的物料成本和维护成本。在电网异常导致电梯断电时,及时为电梯控制系统供电,电梯控制系统驱动电机M运行,以便轿厢运行至最接近的平层,释放被困的乘梯人员,提高了乘梯安全性。
