The invention discloses an elevator power supply system, an elevator and an elevator power supply switching control method.In the elevator power supply system, an input port of a power supply conversion module is connected with a power grid power source and a standby power source, and an output port of the power supply conversion module is connected with a main loop of the elevator; the power supply conversion module sends a power grid power supply switching request to the main control board if detecting that the power grid power supply returns to normal when the standby power supply supplies power, the main control board determines whether a power supply switching condition is met when receiving the power grid power supply switching request, and if yes, a power grid power supply switching instruction is sent to the power supply conversion module; when the power supply conversion module receives the power grid power supply switching instruction, standby power supply power supply is switched to power grid power supply power supply, so that it is ensured that power supply switching is conducted when the elevator stops running and meets the power supply switching condition, safety failures, sudden stop and the like caused by power supply switching during elevator running are avoided, the risk of safety accidents during power supply switching is reduced, and the safety of the elevator is improved. And the safety performance and the riding experience of the elevator are improved.

    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,供电转换模块的输入端口分别与电网电源和备用电源连接,供电转换模块的输出端口与电梯的主回路连接,供电转换模块在备用电源供电时若检测到电网电源恢复正常,向主控板发送电网电源切换请求,主控板在接收到电网电源切换请求时确定是否满足供电切换条件,若是,则向供电转换模块发送电网电源切换指令,供电转换模块在接收到电网电源切换指令时,从备用电源供电切换至电网电源供电,以确保电梯停止运行满足供电切换条件下进行电源切换,避免了电梯运行时进行电源切换发生安全故障、急停等,降低了电源切换时发生安全事故的风险,提高了电梯的安全性能和乘坐体验。
