Title:
ハンドレール駆動力診断装置及びハンドレール駆動力診断方法
Document Type and Number:
Japanese Patent JP6884728
Kind Code:
B2
Abstract:
To solve the problem in that a handrail may be delayed with respect to a footstep surface at the timing when handrail driving force larger than driving force of the traveling handrail is required.SOLUTION: The handrail driving force diagnostic device 19 includes a footstep speed detection unit 20 for detecting the footstep speed, a handrail speed detection unit 21 for detecting the handrail speed, a drive acceleration setting unit 25 for setting second acceleration normally driving a driving motor 2 in an operation direction, which is larger than first acceleration, to a control device 5 as the acceleration set for the control device, and a diagnostic unit for diagnosing that the driving force of a handrail 15 is normal in the case where a period required until the footstep speed is synchronized with the handrail speed from the time point when the driving motor 2 is driven at the second acceleration, which is set to the control device 5, is less than a control value and diagnosing that the driving force of the handrail 15 is abnormal in the case where it exceeds the control value.SELECTED DRAWING: Figure 4
