Document Type and Number:
WIPO Patent Application WO/2021/186621
Kind Code:
A1
Abstract:
Provided is an information collection system that is suitable for collecting information used for inferring a portion of a rope in which an abnormality has occurred. An information collection system (15) is provided with a storage unit (17), a candidate extraction unit (19), and a path calculation unit (22). The storage unit (17) stores, for each of a plurality of sense units, a positional relationship between a cage (6) and a portion of a rope present within the sensibility range. The plurality of sense units provided to the rope react to an abnormality of the rope present in a plurality of the sensibility ranges. When an abnormality of the rope is detected, the candidate extraction unit (19) extracts portions of the rope present in the sensibility ranges of the plurality of sense units as a plurality of candidates of the portions to which the abnormality has occurred, by using the relationships stored in the storage unit (17). The path calculation unit (22) calculates at least one operation path in which at least one of the plurality of candidates passes at least one of the sensibility ranges of the plurality of sense units.
