The invention discloses an elevator control system and method, a controller, an elevator and a readable storage medium. The elevator control system comprises a bus capacitor, a first switch module, a voltage converter and a controller. The motor is used for driving a traction sheave in the elevator. And the first switch module is used for realizing power-on or power-off of the motor. The voltage converter is used for operating when the voltage of the input power supply is smaller than a first voltage threshold value so as to convert the voltage on the bus capacitor into a first voltage and a second voltage and outputting a feedback signal to the controller, the first voltage is used for supplying power to the first switch module, and the second voltage is used for supplying power to a band-type brake of the motor; normal operation of the first switch module and the motor is kept. The controller is used for controlling operation of the motor in a preset control mode in response to the feedback signal. By means of the mode, operation of the elevator can be maintained through the voltage of the bus capacitor, and the success rate of passenger rescue is increased.

    本申请公开了一种电梯控制系统及方法、控制器、电梯及可读存储介质。电梯控制系统包括母线电容、第一开关模块、电压转换器与控制器。电机用于驱动电梯中的曳引轮。第一开关模块用于实现电机的得电或失电。电压转换器用于在输入电源的电压小于第一电压阈值时运行,以将母线电容上的电压转换为第一电压与第二电压,并输出反馈信号至控制器,其中,第一电压用于为第一开关模块供电,第二电压用于为电机的抱闸供电,以保持第一开关模块与电机的正常运行。控制器用于响应于反馈信号而以预设控制方式控制电机的运行。通过上述方式,能够利用母线电容的电压维持电梯的运行,提高对乘客救援的成功率。
