According to the high-voltage door lock detection circuit and the elevator, voltage reduction processing is carried out on a high-voltage door lock signal, when the voltage of the processed high-voltage door lock signal is between a first preset voltage and a second preset voltage, a first potential signal is output, and otherwise, a second potential signal is output. And the high-voltage door lock detection circuit judges the on-off state of the high-voltage door lock according to the first potential signal and the second potential signal. The first potential signal and the second potential signal are obtained by comparing the high-voltage door lock signal subjected to voltage reduction processing with the first preset voltage and the second preset voltage. Therefore, the time for judgingthe on-off state of the high-voltage door lock according to the first potential signal or the second potential signal is shortened. 本申请公开了一种高压门锁检测电路和一种电梯，通过对高压门锁信号进行降压处理，当处理后的高压门锁信号的电压介于第一预设电压和第二预设电压之间时，输出第一电位信号，反之，则输出第二电位信号
