Title:
SENSING DEVICE AND SENSING DEVICE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/005755
Kind Code:
A1
Abstract:
This sensing device (100) comprises: a plurality of sensing units (14), each of which has a magnetic sensor (15) that is an element arranged on one of a first structure and a second structure, and a magnet (16) that is an element arranged on the other of the first structure and the second structure, the plurality of sensing units (14) detecting a relative change in position of the magnetic sensors (15) and the magnets (16) on the basis of a change in magnetic flux detected by the magnetic sensors (15); a computation unit (25) that derives a measurement result pertaining to at least one from among the amount of movement of the first structure relative to the second structure, the amount of rotation of the first structure relative to the second structure, and an external force received by the first structure, the measurement result being derived according to a computation based on results of detection performed by each of the plurality of sensor units (14); and an assessment unit (26) that assesses, on the basis of the results of detection performed by each of the plurality of sensor units (14), whether an abnormality has occurred in which the magnetic flux changes due to a factor other than the relative change in position of the magnetic sensors (15) and the magnets (16).
