Title:
SLIPPAGE ESTIMATION DEVICE AND SLIPPAGE ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/188636
Kind Code:
A1
Abstract:
A slippage estimation device (100, 101, 102) comprises: a slippage acquisition unit (110) that acquires slippage information indicating slippage of a rope (23) for moving a car (24), which has been measured in a test operation during an inspection implemented on an elevator (20); a clustering unit (150) that classifies a characteristic of elevator (20) slippage into one cluster from a plurality of predetermined clusters on the basis of the slippage information for the elevator (20) acquired by the slippage acquisition unit (110) and outputs the cluster information indicating the classified cluster; and a slippage estimation unit (160, 161) that estimates the slippage in a test operation during the next inspection to be implemented on the elevator (20) on the basis of the cluster information output by the clustering unit (150) and the slippage information for the elevator (20) acquired by the slippage acquisition unit (110) and that outputs the estimated slippage information indicating the estimated slippage.
