Title:
ELEVATOR CONTROL SYSTEM AND ELEVATOR CONTROL METHOD
Document Type and Number:
Japanese Patent JP2020179959
Kind Code:
A
Abstract:
To provide an elevator control system capable of reducing sound caused by intake/exhaust device.SOLUTION: An elevator control system controls an atmospheric pressure in a car by controlling an intake/exhaust device according to an atmospheric pressure control pattern that defines the relation between time and atmospheric pressure. The elevator control system comprises: a storage part to store multiple atmospheric pressure control patterns that the maximum pressure difference in the time variation of the atmospheric pressure in the car is different when the atmospheric pressure in the car is not controlled; a changing part to change the atmospheric pressure control pattern used for controlling the atmospheric pressure in the car to the atmospheric pressure control pattern that the maximum atmospheric pressure difference is small; and an atmospheric pressure control part to control the atmospheric pressure in the car through controlling the intake/exhaust device according to the atmospheric pressure control pattern changed by the changing part.SELECTED DRAWING: Figure 1
