Abstract | 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.
