In this case, the control unit 110 indicates that the recorded person detection information indicates that a person has been detected when the door 20 is opened, and the person detection information indicates that the person has been detected when the door 20 is closed. Since it has been detected, it is determined that there has been no entry or exit. In this case, the output unit 140 does not output “room entry information” indicating that the person has entered the room or “room exit information” indicating that the person has exited. As described above, the control unit 110 does not detect entry or exit when a person comes near the front of the door 20 and opens and closes the door 20 but does not enter the room. That is, even if a person takes the above actions, the control unit 110 does not detect entry / exit by mistake.
- the time is as shown in FIG. 4F. That is, (1) When a person opens the door 20, the signal output from the open / close detection sensor 120 changes to an open signal (time point Tf1). Since there is no person on the front surface of the door 20 at this time, the signal output from the person detection sensor 130 is a person non-detection signal, and the control unit 110 indicates that no person has been detected when the door 20 is opened.
- the opening person detection information shown is recorded.

In this case, the output unit 140 does not output “room entry information” indicating that the person has entered the room or “room exit information” indicating that the person has exited. As described above, the control unit 110 does not detect entry or exit when a person comes near the back of the door 20 and opens or closes the door 20 but does not enter the room. That is, even if a person takes the above actions, the control unit 110 does not detect entry / exit by mistake.
- the entrance / exit detection device 100 erroneously indicates that there is no entrance or exit even if the open / close detection sensor 120 and the person detection sensor 130 may react individually. “Information” and “Exit information” are not output.

実施の形態1に係る入退室検出装置100は、人が監視対象の出入り口を通って入室したこと、あるいは監視対象の出入り口を通って退室したことを検出し、監視者あるいは他機器に入室あるいは退室があったことを通知する。
開閉検出センサ120は、扉の状態が開状態である間は、開状態であることを示す開信号を制御部110に供給し、扉の状態が閉状態である間は、閉状態であることを示す閉信号を制御部110に供給する。
人検出センサ130は、検出可能領域に人が存在する間は、人が存在することを示す人検出信号を制御部110に供給し、検出可能領域に人が存在しない間は、人が存在しないことを示す人非検出信号を制御部110に供給する。
図2Aに示すように、検出対象領域(領域A130)に人が存在しない場合、人検出センサ130は、人非検出信号を制御部110に供給する。また、図2Bに示すように、検出対象領域(領域A130)に人30が存在する場合、人検出センサ130は、人検出信号を制御部110に供給する。
機器40は、入室あり情報あるいは退室あり情報を受信すると、受信した入室あり情報あるいは退室あり情報を画面上に表示する。また、機器40は、入室あり情報を受信すると、入室あり情報に対応する効果音をスピーカーから出力し、退室あり情報を受信すると、退室あり情報に対応する効果音をスピーカーから出力する。このようにして、機器40は、入室があったことあるいは退室があったことを監視者に通知する。また、機器40は、入室あり情報および退室あり情報のそれぞれが供給された回数をカウントすることにより、入室した人の人数および退室した人の人数を計数する。
また、制御部110は、ユーザによる停止操作(入退室検出装置100のシャットダウン等)がなされるまで、ステップS110~161の処理を繰り返し実行する。
人は、監視対象の出入り口を通って入室する場合、(1)扉20の前面に立ち(この時点をTa1とする)、(2)扉20を開き(この時点をTa2とする)、(3)出入り口を通り(この時点をTa3とする)、その後に(4)扉20を閉める(この時点をTa4とする)、といった順に行動する。
以上において示したとおり、制御部110は、人が監視対象の出入り口を通って入室した場合、入室があったことを正しく検出する。
人は、監視対象の出入り口を通って退室する場合、扉20の背面に立ってから(1)扉20を開き(この時点をTb1とする)、(2)出入り口を通り(この時点をTb2とする)、(3)扉20を閉め(この時点をTb3とする)、(4)最後に扉20の前面から離れる(この時点をTb4とする)といった順に行動する。
以上において示したとおり、人が監視対象の出入り口を通って退室した場合、制御部110は退室があったことを正しく検出する。
人が扉20の前面に立ったものの、扉20を開閉することなく扉20の前面から離れた場合における、人検出センサ130の出力が「人検出信号」および開閉検出センサ120の出力が「開信号」となる時間は、図4Cに示したとおりである。すなわち、人が扉20の前面に立つことにより人検出センサ130が出力する信号は人検出信号となり(この時点をTc1とする)、人が扉20の前面から離れることにより人検出センサ130が出力する信号は人非検出信号となる(この時点をTc2とする)。人がこの一連の動作をしても、開閉検出センサ120が出力する信号は閉信号から変化しない。この場合、制御部110は、開時人検出情報あるいは閉時人検出情報の記録をせず、また入室があったことも退室があったことも検出しない。
以上において示したとおり、人が扉20の前面付近に来たが、扉20を開閉することなく立ち去った場合は、制御部110は入室も退室も検出しない。つまり、以上のような行動を人がとったとしても、制御部110が誤って入退室を検出することはない。
人が扉20の背面に立ったものの、扉20を開閉することなく扉20の背面から離れた場合、図4Dに示すとおり、人検出センサ130が出力する信号も開閉検出センサ120が出力する信号も一連の動作を通じて変化しない。この場合、制御部110は、開時人検出情報あるいは閉時人検出情報を記録せず、また入室があったことも退室があったことも検出しない。つまり、以上のような行動を人がとったとしても、制御部110が誤って入退室を検出することはない。
この場合、人は、(1)扉20の前面に立ち(この時点をTe1とする)、(2)扉20を開き(この時点をTe2とする)、(3)その後、扉20を閉じ(この時点をTe3とする)、最後に(4)扉20の前面付近から離れる(この時点をTe4とする)、といった順に行動する。
以上において示したとおり、制御部110は、人が扉20の前面付近に来て扉20を開閉したが、入室しなかった場合、入室も退室も検出しない。つまり、以上のような行動を人がとったとしても、制御部110が誤って入退室を検出することはない。
この場合、人は、扉20の背面に立って(1)扉20を開き(この時点をTf1とする)、(2)その後扉20を閉じて(この時点をTf2とする)戻る、といった順に行動をとる。
以上において示したとおり、制御部110は、人が扉20の背面付近に来て扉20を開閉したが、入室しなかった場合、入室も退室も検出しない。つまり、以上のような行動を人がとったとしても、制御部110が誤って入退室を検出することはない。
圧電センサ130bは、検出面に圧力が働いた場合に内部電圧が変化することにより、検出面上に人が存在することを検出する。図6Aに示すように、圧電センサ130bは、扉20前面付近の床面に設置される。そして、圧電センサ130bは、図6Bに示すように、圧電センサ130b上に人30がいる場合、人30の体重により検出面に圧力が加えられ、圧電センサ130bの内部電圧の変化を検出することにより、検出面上に人30が存在することを検出する。
また、他にも本発明に適用できる人検出センサは多々存在する。例えば人検出センサが赤外線センサ、超音波センサ、可視光センサのいずれであっても本発明は実現される。
さらに、出力部140は、他機器に情報を供給することに代えて、例えば出力部140に直接接続されたディスプレイの所定欄に「入室あり」あるいは「退室あり」と表示するようにしてもよい。また、出力部140は、出力部140に直接接続されたスピーカーから入退室があったことを音声出力してもよい。
本実施の形態では、実施の形態1で示した入退室検出装置と同等の機能を提供しつつ、さらに消費電力を低減した入退室検出装置について説明する。
開時人検出処理の最初に、制御部110は、人検出センサ130を動作状態にする(ステップS211)。具体的には、制御部110は、バス101を介し、人検出センサ130を動作状態にするための所定の信号を省電力制御部150に供給する。省電力制御部150は、制御部110からの所定の信号の供給を受信すると、人検出センサ130への電力供給を開始し、人検出センサ130の状態を動作状態に切り替える。
閉時人検出処理の最初において、制御部110は、人検出センサ130を動作状態にする(ステップS221)。具体的には、制御部110は、バス101を介して人検出センサ130を動作状態にするための所定の信号を省電力制御部150に供給する。省電力制御部150は、制御部110からの所定の信号の供給を受信すると、人検出センサ130への電力供給を開始し、人検出センサ130の状態を動作状態に切り替える。
上記実施の形態においては、開閉検出センサ120は、加速度センサ120aを備えるものであったが、扉20の開閉を検出できるものであれば加速度センサ120aの代わりに例えば接触スイッチ、位置センサ、距離センサのいずれかを備えていてもよい。
人検出部211は、焦電型赤外線センサ、重量センサ等の任意の人の存在を検出できるセンサを備え、扉の一面側の検出対象領域内の人を検出する。
開閉検出部212は、加速度センサ、位置センサ、接触センサ等を備え、扉が開いた状態か閉じた状態かを検出する。
開時人検出情報記録部213は、開閉検出部212が扉が閉じた状態から開いた状態に切り替わったことを検出したときに、人検出部211が、人を検出しているか否かを記録する。
閉時人検出情報記録部214は、開閉検出部212が扉が開いた状態から閉じた状態に切り替わったことを検出したときに、人検出部211が、人を検出しているか否かを記録する。
入退室検出部215は、開時人検出情報記録部213と閉時人検出情報記録部214とが記録した内容に基づいて、例えば、図3に示したステップS150、ステップS151、ステップS160、ステップS161と同等のロジックにより、入室・退室の有無を検出する。また、入退室検出部215は、検出した入室・退室の有無を他機器に出力する。
このような構成によっても、本発明の課題は達成され、また、本願発明の効果が奏される。
