Title:
ELEVATOR CONTROL DEVICE AND ELEVATOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/171423
Kind Code:
A1
Abstract:
This elevator control device comprises a first controller that executes safety monitoring control, a second controller that controls operation of a car, a first power supply line that is always supplied power, and a second power supply line that switches, on the basis of a control signal output from the first controller, to one of either a power supply state or a shutoff state. The second controller determines from the operation status of the car whether to place the second power supply line in the shutoff state and sends a shutoff request command to the first controller when it has been determined to place the second power supply line in the shutoff state; when the shutoff request command is received from the second controller, the first controller outputs a control signal so that the second power supply line is placed in the shutoff state.
