Document Type and Number:
WIPO Patent Application WO/2024/062652
Kind Code:
A1
Abstract:
[Problem] To provide a height difference reducing device, platform, and user guidance assistance system with an accurate failure prediction function that can be used for condition-based maintenance. [Solution] A height difference reducing device 100 is embedded in a platform 200 to reduce the gap and height difference between a train entrance and the platform 200 is provided, and comprises a pivotally supported pivotable surface 110, a vertical lifting mechanism that raises and lowers the pivotable surface 110 by an inverted V-shaped link mechanism 300, a detection sensor comprising a plurality of sensors provided on the pivotable surface 110 or an extendable surface 120, a control unit 500 that controls the vertical lifting mechanism and the detection sensor, and a failure prediction unit 570 that predicts a failure of the vertical lifting mechanism.
