The invention discloses an elevator power supply system, an elevator and an elevator power supply switching control method.In the elevator power supply system, the input end of a power module of the elevator is connected with a power grid power source and a power supply conversion module, the input end of the power supply conversion module is connected with a battery and a standby power source, and the power supply conversion module is in communication connection with a main control board; the power supply conversion module detects whether the standby power supply is normal or not when the power supply conversion module receives a power grid power supply abnormal signal from the power supply module and communication with the main control board is abnormal in the power supply process of the power grid power supply, if yes, the standby power supply supplies power to the power supply module, and if not, the battery supplies power to the power supply module, so that the power supply conversion module is connected to the battery and the standby power supply; when the power grid power supply is abnormal, the standby power supply is used for supplying power preferentially, the problem that the elevator stops service after the battery power supply is used up is avoided, the standby power supply can be used for supplying power to the elevator when the power grid power supply is abnormal, and the elevator can normally serve after the power grid power supply is abnormal.

    本发明公开了一种电梯供电系统、电梯及电梯供电切换控制方法,在电梯供电系统中,电梯的电源模块的输入端分别与电网电源和供电转换模块连接,供电转换模块的输入端分别与电池和备用电源连接,供电转换模块与主控板通信连接,供电转换模块在电网电源供电的过程中,从电源模块接收到电网电源异常信号且与主控板通信异常时,检测备用电源是否正常,若是,通过备用电源对电源模块供电,若否,通过电池对电源模块供电,实现了供电转换模块接入电池和备用电源,在电网电源异常时优先通过备用电源供电,避免了采用电池供电电量耗尽后导致电梯停止服务的问题,能够在电网电源异常时通过备用电源为电梯供电,使得电梯在电网电源异常后能够正常服务。
