Abstract
A diagnosing device identifies a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail; obtains drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door; and diagnoses an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.
Claims10
A diagnosing device comprising circuitry, the circuitry being configured to perform:
- identifying a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail;
- obtaining drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door;
- and
- diagnosing an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.
A diagnosing method comprising:
- identifying, by circuitry a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail;
- obtaining, by the circuitry, drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door;
- and
- diagnosing, by the circuitry, an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.
A non-transitory computer-readable medium storing a diagnosing program, when executed by circuitry, the diagnosing program causes the circuitry to perform:
- identifying a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail;
- obtaining drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door;
- and
- diagnosing an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.
