Title:
ELEVATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/106709
Kind Code:
A1
Abstract:
This elevator system (100) is provided with an elevator (20) having a seismic sensor (220), and a monitoring center (300). The elevator (20) pauses operation when the seismic sensor (220) has detected a high acceleration that exceeds an operation pause threshold value, and transmits a high acceleration detection signal and an operation pause signal to the monitoring center (300). The monitoring center (300) has elevator passenger data (45) which stores the ground amplification factor of the region where the elevator (20) is installed. Upon receiving a high acceleration detection signal and an operation pause signal from the elevator (20), if the seismic intensity in the region where the elevator (20) is installed is less than a seismic intensity threshold value and the ground amplification factor of said region is less than a prescribed threshold value, the monitoring center (300) transmits a signal for the elevator (20) to perform an automatic recovery diagnostic operation.
