Title:
エレベーターシステム
Document Type and Number:
Japanese Patent JP7138773
Kind Code:
B2
Abstract:
An elevator system includes a car that ascends and descends a hoist way, a power feeding device installed at a specific power feeding point of the hoist way, a power receiving device that receives power from the power feeding device when the car stops at the power feeding point, a battery that is charged by the received power, and an elevator control panel that controls ascent and descent of the car. When the remaining capacity of the battery is equal to or less than a predetermined capacity, the elevator control panel performs a rescue operation of a passenger in the car, and after the rescue operation, performs an automatic search operation of searching for a power feeding point where the power feeding device is installed according to the remaining capacity of the battery. As a result, when the battery of the car is depleted and the power feeding point cannot be detected, it is possible to return to a normal operation state without performing an operation by a maintenance worker.
