ROOM ENTRY/EXIT DETECTION APPARATUS, ROOM ENTRY/EXIT DETECTION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON

摘要

A person detector detects a person in an area facing one door surface. An open/close detector detects whether the door is in an open or closed state. When a detected state of the door switches from a closed state to an open state, an open-state person detection information recorder records whether the person detector is detecting a person or not. When the state of the door detected by the open and close detection sensor switches from the open state to the closed state, a closed-state person detection information recorder records whether the person detector is detecting a person or not. A room entry and exit detector detects that there occurs an entry into the room and there occurs an exit out of the room on the basis of a content recorded by the open-state person detection information recorder and the closed-state person detection information recorder.

主权项

1. A room entry and exit detection apparatus comprising:
a person detection sensor configured to detect a person in an area facing one surface of a door; an open and close detection sensor configured to detect whether the door is in an open state or in a closed state; an open-state person detection information recorder, wherein when a state of the door detected by the open and close detection sensor switches from a closed state to an open state, the open-state person detection information recorder is configured to record whether the person detection sensor is detecting a person or not at that point in time; a closed-state person detection information recorder, wherein when the state of the door detected by the open and close detection sensor switches from the open state to the closed state, the closed-state person detection information recorder is configured to record whether the person detection sensor is detecting a person or not at that point in time; and a room entry and exit detector configured to detect that there occurs an entry into the room and there occurs an exit out of the room on the basis of a content recorded by the open-state person detection information recorder and the closed-state person detection information recorder.
