Abstract
A monitoring apparatus includes a sensing circuitry configured to sense a locked or released state of a door of a railway vehicle, or sense an open or closed state of the door, and a processor. The processor acquires an output of the sensing circuitry, and position information in an opening or closing direction of the door, and determines an abnormality in a configuration related to an opening or closing operation of the door, based on a match between the acquired output of the sensing circuitry and the position information.
