Abstract

The present invention relates to a method for controlling an operation of an elevator, which is capable of moving the elevator to a near floor by using an auxiliary power supply such as a battery in an emergency situation where a commercial power supply cannot be used, while minimizing power consumption through automatic control. The method includes: detecting the current operation zone of the elevator when an auxiliary power supply driving situation occurs; and operating the elevator by using the auxiliary power supply to correspond to the detected current operation zone. The detected current operation zone corresponds to one of an acceleration zone, a constant speed zone, a creep zone and a seating zone.

First claim

What is claimed is:

1. A method for controlling an operation of an elevator, comprising:
detecting a current operation zone of an elevator when an auxiliary power supply driving situation occurs;
operating the elevator by using the auxiliary power supply to correspond to the detected current operation zone;
measuring an output current in a forward test operation for the elevator;
measuring an output current in a backward test operation for the elevator; and
making a comparison in output current between the forward test operation and the backward test operation;
determining that a difference in output current between the forward test operation and the backward test operation falls within a margin of error; and
determining the operation direction of the elevator as a direction in which the elevator is closer to a near floor, based on position information of the elevator,
wherein the detected current operation zone corresponds to a constant speed zone.
