【発明の実施の形態】
以下、図面を参照し、本発明の実施形態について説明する。
図１は、本発明の第１の実施形態による環境制御システムの構成を示すブロック図である。この図１に示す環境制御システムは、温度等の環境を制御するための環境制御処理を行う環境制御装置１と、この環境制御装置１の制御に従って温度等の空気状態を調節する空調装置２と、無線により通信可能な無線端末３と、この無線端末３との間で無線により通信し、該無線端末３と環境制御装置１との間で情報の伝達を行う無線基地局４とから構成される。上記無線端末３はその利用者により携帯可能な構造を有する。
【００１４】
空調装置２はそれぞれの空調対象の領域Ａ−１〜Ｎ（Ｎ；自然数）に設置されている。例えば、図２に示すように、建物内の空調対象の全領域を九つの領域Ａ−１〜９に分割し、それぞれの領域Ａ−１〜９に空調装置２を設置する。なお、各領域Ａ−１〜Ｎには空調装置２が一装置だけ設置されていてもよく、あるいは複数が設置されていてもよい。また、上記領域Ａ−１〜Ｎがそれぞれ環境制御対象領域に対応する。
【００１５】
図１の環境制御装置１において、符号１１は、無線基地局４を介して無線端末３との間で通信を行う通信部である。符号１２は、通信部１１により無線端末３の環境情報を収集し、この情報に基づいて環境制御指示処理を行う処理部である。符号１３は、処理部１２の指示に従って空調装置２の制御を行う制御部である。上記環境情報は、無線端末３の位置を特定可能な位置情報と、無線端末３の利用者の体感情報とを含む。この体感情報は、「暑い」、「寒い」、「適温」のいずれかの情報であり、利用者によって無線端末３に設定されるものである。
【００１６】
なお、上記処理部１２は専用のハードウェアにより実現されるものであってもよく、また、この処理部１２はメモリおよびＣＰＵ（中央処理装置）により構成され、処理部１２の機能を実現するためのプログラムをメモリにロードして実行することによりその機能を実現させるものであってもよい。
【００１７】
また、無線端末３は、人工衛星からの信号を受信し、この受信信号により自己の位置を示す位置情報を取得可能なＧＰＳ（Global Positioning System）装置（以下、単にＧＰＳと称する）３１を備える。無線端末３は、このＧＰＳ３１により自装置の位置情報を取得する。また、無線端末３は、上記体感情報の設定手段を備える。この設定手段は「暑い」、「寒い」、「適温」のいずれかを選択して設定可能な構成となっている。
【００１８】
例えば、体感情報設定手段は、「暑い」設定ボタンと「寒い」設定ボタンと設定・解除ボタンからなり、いずれかの設定ボタンを押下して設定・解除ボタンを押下すれば当該設定（「暑い」または「寒い」のいずれか）を保持する。この後、再度、設定・解除ボタンを押下すれば設定が解除される。この解除状態において体感情報は「適温」となる。
【００１９】
次に、図１の環境制御システムが温度環境を制御する動作について説明する。図３は、図１に示す環境制御装置１の処理部１２が行う第１の環境制御指示処理の流れを示すフローチャートである。図４は、図１に示す環境制御装置１の処理部１２が行う第２の環境制御指示処理の流れを示すフローチャートである。
以下の説明において、環境制御装置１の通信部１１と無線端末３はそれぞれ無線基地局４を介して接続されているが、特に説明がない場合は、この無線基地局４を介してデータ等の送受が行われるものとする。
【００２０】
初めに、図３を参照して、第１の環境制御指示処理による動作を説明する。利用者は無線端末３を携帯して領域Ａ−１〜Ｎのいずれかの領域へ進入する。ここで、各領域Ａ−１〜Ｎには、利用者が単数または複数居てもよく、あるいは誰も居なくてもよい。また、環境制御装置１の処理部１２には、無線端末３の位置情報と各領域Ａ−１〜Ｎとの対応付けが予め設定されている。
【００２１】
先ず、環境制御装置１の処理部１２は、通信部１１により各無線端末３からそれぞれの位置情報を取得する。処理部１２は、これら位置情報に基づいてそれぞれの無線端末３が位置している領域を領域Ａ−１〜Ｎの中から特定する（図３のステップＳ１、Ｓ２）。次いで、処理部１２は、領域Ａ−１〜Ｎ毎に、無線端末３の数を求め、この数と過去に求めた当該領域の無線端末３の数との差分から無線端末３の増減数を算出する。この端末増減数がゼロの場合には、処理部１２は、その処理を終了する（図３のステップＳ３、Ｓ４）。
【００２２】
一方、無線端末３の増減があった場合には、処理部１２は、増減があった領域毎に、その端末増減数に基づいて当該領域内の発生熱量の増減量（発生熱増減量）を算出する。この発生熱量とは領域内に居る人から発生される熱量のことである。処理部１２は、一人当りの所定発生熱量に各領域の端末増減数を乗じて、各領域の発生熱増減量を求める。次いで、処理部１２は、各領域の発生熱増減量を制御部１３へ通知して当該領域内の温度を所定温度に保つように指示する（図３のステップＳ５、Ｓ６）。
【００２３】
次いで、制御部１３は、温度制御を指示された領域の空調装置２に対し、それぞれ通知された発生熱増減量に基づいて温度調節動作の制御を行う。これにより、利用者の増減があった領域内の温度が自動的に所定温度に保たれることになる。
【００２４】
次に、図４を参照して、第２の環境制御指示処理による動作を説明する。利用者は無線端末３を携帯して領域Ａ−１〜Ｎのいずれかの領域へ進入している。また、利用者は、自己の無線端末３の体感情報設定手段により、「暑い」、「寒い」、「適温」のいずれかを選択して体感情報を設定する。これにより、無線端末３は「暑い」、「寒い」、「適温」のいずれかの体感情報を有することになる。
【００２５】
先ず、環境制御装置１の処理部１２は、各無線端末３からそれぞれの位置情報と体感情報を取得する。処理部１２は、各位置情報に基づいてそれぞれの無線端末３が位置している領域を領域Ａ−１〜Ｎの中から特定する（図４のステップＳ１１、Ｓ１２）。次いで、処理部１２は、領域Ａ−１〜Ｎ毎に、各無線端末３の体感情報を集計する。ここで、処理部１２は、領域Ａ−１〜Ｎ毎に、「暑い」の無線端末３の数と「寒い」の無線端末３の数を求め、いずれの体感情報を有した無線端末３の数が多いか判断する（図４のステップＳ１３）。
【００２６】
次いで、処理部１２は、その集計結果に基づいて各領域Ａ−１〜Ｎの温度制御指示を実行する。ここで、処理部１２は、体感情報「暑い」を有した無線端末３の数が多い領域に対しては、制御部１３へ温度下降を指示する。一方、体感情報「寒い」を有した無線端末３の数が多い領域に対しては、制御部１３へ温度上昇を指示する。また、体感情報「暑い」と「寒い」を有した各々の無線端末３の数が同数の領域に対しては、温度制御指示を行わない。
【００２７】
次いで、制御部１３は、指示された領域の空調装置２に対し、それぞれの温度制御指示に基づいて温度調節動作の制御を行う。これにより、利用者の体感情報がそれぞれの領域内の空調に反映されることになる。
【００２８】
なお、上述した実施形態において、図１に示す環境制御装置１の処理部１２が、上記図３に示す第１の環境制御指示処理、または図４に示す第１の環境制御指示処理のいずれかの処理を行うようにしてもよく、あるいは双方の処理を組み合わせて行うようにしてもよい。
【００２９】
次に、本発明の第２の実施形態について説明する。図５は、本発明の第２の実施形態による環境制御システムの構成を示すブロック図である。この図５において図１の各部に対応する部分には同一の符号を付け、その説明を省略する。図５に示す第２の実施形態は、無線端末の位置を特定可能な無線通信システムを利用して、無線端末の位置情報を取得するようにしたものである。この無線通信システムとしては、ＰＨＳ（登録商標）（Personal Handy-phone System）が利用可能である。
【００３０】
図５に示すように、領域Ａ−１〜Ｎにはそれぞれ無線基地局４１が設置される。この無線基地局４１は、領域Ａ−１〜Ｎの内で自己が設置された領域を含み、且つこの領域にほぼ等しい範囲を無線通信提供範囲としている。これら無線基地局４１は環境制御装置１の通信部１４に接続される。通信部１４は、それぞれの無線基地局４１を介して、領域Ａ−１〜Ｎ内に位置する無線端末３２との間で通信を行うことができる。また、無線基地局４１は、自己の無線通信提供範囲内に位置する無線端末３２を把握可能である。通信部１４は、無線基地局４１からその無線通信提供範囲内に位置する無線端末３２の位置情報を取得する。この位置情報は、無線端末３２がいずれの領域Ａ−１〜Ｎの無線基地局４１を介して通信しているかを示す。環境制御装置１の処理部１２は、この位置情報によりその無線基地局４１の設置領域を当該無線端末３２が位置する領域として特定する。また、無線端末３２は上記図１の無線端末３と同様に、体感情報設定手段を備える。
【００３１】
図５の環境制御システムにおいて、環境制御装置１の処理部１２は、第１の実施形態と同様に、上述した図３に示す第１の環境制御指示処理、または図４に示す第１の環境制御指示処理のいずれかの処理を行う。あるいは双方の処理を組み合わせて行うようにしてもよい。
【００３２】
なお、上述した実施形態においては、環境調節手段として空調装置２を備え、この空調装置２により温度の高低を調節するようにしたが、調節する環境は温度に限定されるものではない。例えば、湿度の高低を調節するようにしてもよい。この場合には体感情報は、「湿気が多い」、「適度」、「乾燥」のいずれかの情報となる。また、環境調節手段として照明調節装置を備え、この照明調節装置により照明の強弱を調節するようにしてもよい。この場合には体感情報は、「暗い」、「適度」、「明る過ぎ」のいずれかの情報となる。
【００３３】
また、上述した実施形態は、オフィスビル、ホテル、美術館、博物館、イベント会場等の建物の他、列車や船舶などにも応用可能である。
【００３４】
以上、本発明の実施形態を図面を参照して詳述してきたが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。
【００３５】
【発明の効果】
以上説明したように、本発明によれば、携帯可能な無線端末の位置を特定可能な位置情報を取得し、この位置情報に基づいて無線端末が位置する環境制御対象領域を特定し、環境制御対象領域内に位置する無線端末の増減数を求め、この増減数に基づいて、環境調節手段が行う環境制御対象領域の環境調節動作を制御する。これにより、その無線端末を携帯した人の移動に応じて、その移動先または移動元の領域の環境（温度等）を調節することができるという効果が得られる。
【００３６】
また、携帯可能な無線端末の位置を特定可能な位置情報を取得し、この位置情報に基づいて無線端末が位置する環境制御対象領域を特定し、無線端末に設定された体感情報を取得し、環境制御対象領域に係る体感情報を集計し、この集計結果に基づいて、環境調節手段が行う環境制御対象領域の環境調節動作を制御するようにすれば、その無線端末を携帯した人の好みに応じて体感情報が設定されるので、この結果、人の好みに応じてその人が位置する領域の環境（温度等）を調節することができ、過分なエネルギー消費を抑制するという効果が得られる。
