Abstract
A diagnostic apparatus acquires time series data during a time period in which a door closes, upon occurrence of a condition in which a door-side pin in a train carriage is maintained in a state where a locking device does not restrict the pin from moving downward, the time series data including first time series data of a position of the door, and second time series data of an output of a detector configured to detect whether the pin has dropped. The diagnostic apparatus diagnoses, based on the acquired time series data, an abnormality in a positional relationship between the pin and a car-side recess in an opening and closing direction of the door that is in a locked state.
Claims12
A diagnostic apparatus comprising:
- circuitry configured to:
- acquire time series data during a time period in which a door closes, upon occurrence of a condition in which a car-side pin in a train carriage is maintained in a state where a locking device does not restrict the pin from moving downward, the pin being configured to drop into a door-side recess in the train carriage by weight of the pin to allow for a locked state of the door, and the time series data including
- first time series data of a position of the door, and
- second time series data of an output of a detector configured to detect whether the pin has dropped, and
- diagnose, based on the acquired time series data, an abnormality in a positional relationship between the pin and the recess in an opening and closing direction of the door that is in the locked state.
A diagnostic system comprising:
- circuitry configured to:
- close a door in a train carriage, upon occurrence of a condition in which a car-side pin in the train carriage is maintained in a state where a locking device does not restrict the pin from moving downward, the pin being configured to drop into a door-side recess in the train carriage by weight of the pin to allow for a locked state of the door,
- acquire time series data during a time period in which a door closes, the time series data including
- first time series data of a position of the door, and
- second time series data of an output of a detector configured to detect whether the pin has dropped, and
- diagnose, based on the acquired time series data, an abnormality in a positional relationship between the pin and the recess in an opening and closing direction of the door that is in the locked state.
A diagnostic method executed by an information processing apparatus, the diagnostic method comprising:
- acquiring time series data during a time period in which a door is closed, upon occurrence of a condition in which a car-side pin in a train carriage is maintained in a state where a locking device does not restrict the pin from moving downward, the pin being configured to drop into a door-side recess in the train carriage by weight of the pin to allow for a locked state of the door, and the time series data including
- first time series data of a position of the door, and
- second time series data of an output of a detector configured to detect whether the pin has dropped;
- and
- diagnosing, based on the acquired time series data, an abnormality in a positional relationship between the pin and the recess in an opening and closing direction of the door that is in the locked state.
