Description
以下、本開示の第1実施形態に係る機器管理システム1について説明する。なお、以下の実施形態は、具体例であって、技術的範囲を限定するものではなく、趣旨を逸脱しない範囲で適宜変更可能である。
図1は本開示の一実施形態に係る機器管理システム1の構成を示す模式図である。なお、以下の説明において、同様の機能を有する複数の装置について共通の説明をする場合は同一符号を付して説明する。同様の機能を有する複数の装置から、一の装置を区別して説明するときには英小文字の添え字を付して説明する。例えば、制御端末20a~20cはそれぞれ同様の機能を有する装置であるので、説明が共通する場合は制御端末20と表記する。説明の便宜上、添え字a~c等を用いるが、これらは任意の数を表しており、数量がこれに限定されるものではない。
以下、本実施形態に係る機器管理システム1の管理対象である機器として、対象空間の冷房や暖房を行う「空気調和機」を例として説明する。ただし、本実施形態に係る機器管理システム1の管理対象は空気調和機に限られるものではなく、以下の特徴を有する任意の機器を採用することができる。例えば、「機器」として換気装置、調湿装置、エアハンドリングユニット、チラーユニット、及び/又はその他の冷凍装置等を採用してもよい。
図3は本実施形態に係る機器管理システム1を構成する各装置の機能ブロックを示す模式図である。
制御端末20は室外機制御回路11Xに接続することで空気調和機10を制御するものである。各制御端末20は、図3に示すように、記憶部21と、通信部22と、処理部23と、接続部24と、を有する。
管理装置30は、制御端末20及び監視端末40のそれぞれに通信ネットワークNW1を介して接続し、空気調和機10a~10iを含む複数の空気調和機10の運転状態等を管理する。管理装置30は、制御端末20と通信ネットワークNW1を介して通信する。管理装置30は、図3に示すように、記憶部31、入力部32、通信部33、処理部34、及び出力部35を有する。
監視端末40は、いずれかの制御端末20に関連付けられており、その制御端末20に属する空気調和機10(機器)に関連する各種要求を管理装置30に送信する。換言すると、制御端末20を操作する監視者が、いずれかの制御端末20と関連付けられており、その制御端末20に属する空気調和機10に関連する各種要求を管理装置30に送信する。なお、監視端末40(監視者)は、制御端末20と、1対1に関連付けられてもよいし、1対多に関連付けられてもよいし、多体多に関連付けられてもよい。監視端末40は、管理装置30から送信される監視情報に基づいて、空気調和機10の状態を監視する。監視端末40は、例えば、空気調和機10に対して各種制御を実行する権限が付与された監視者により操作される。
保守端末50は、空気調和機10の保守作業者が操作する端末である。保守端末50は、異常発報を管理装置30から受け取る。これにより、保守作業者が、異常発報が検出された空気調和機10の異常診断及び故障対応等を行なうことが可能となる。
図10は本実施形態に係る機器管理システム1における低減制御の例を説明するための模式図である。なお、図10では、1台の管理装置30と、1台の制御端末20と、1台の監視端末40と、の関係における処理の流れが示されているが、管理装置30と、各制御端末20、及び/又は監視端末40と、の間においては、図10のような処理が個別に行われる。
(5-1)
本実施形態では、管理装置30は、機器情報を送信する装置である制御端末20と所定の通信条件に基づき通信ネットワークNW1を介して通信し、通信ネットワークNW1における通信品質を測定する通信品質測定部342と、通信品質の低下の度合いを判定する通信品質判定部343と、通信品質の低下の度合いに応じて低減制御を実行する低減制御部344と、を有している。低減制御部344は、低減制御において、制御端末20及び管理装置30間で伝送される各情報の優先度に応じて通信条件を変更する。これに伴い、通信量が低減する。
本実施形態においては、低減制御部344は、低減制御において、管理装置30から制御端末20への情報の送信に関して通信条件を変更する。これにより、通信ネットワークNW1を介した管理装置30及び制御端末20間の通信に関して、通信ネットワークNW1における通信品質が低下した場合に、管理装置30から制御端末20への情報の送信に関して通信条件が変更されるようになっている。
本実施形態においては、低減制御部344は、低減制御において、制御端末20から管理装置30への情報の送信に関して通信条件を変更させる指令(低減制御通知)を、制御端末20へ送信する。これにより、通信ネットワークNW1を介した管理装置30及び制御端末20間の通信に関して、通信ネットワークNW1における通信品質が低下した場合に、制御端末20から管理装置30への情報の送信に関して通信条件が変更される。
本実施形態においては、制御端末20によって送信される機器情報は空気調和機10に関するものであり、優先度は、空気調和機10の設置状況、利用状況、属性、及び監視目的の少なくとも一つに基づき決定される。これにより、通信ネットワークNW1を介して空気調和機10の管理を行うシステムにおいて、管理装置30と制御端末20間の通信に関して、通信ネットワークNW1における通信品質が低下した場合に、通信条件を細やかに決定することが可能となっている。
本実施形態においては、管理装置30の処理部34及び通信部33(第1通知部)は、低減制御部344が低減制御を実行する際に所定の監視端末40に対して低減制御を実行していることを通知する。これにより、低減制御が行われていることを監視者(ユーザやシステム運用者)が把握可能となっている。
本実施形態においては、低減制御部344は、低減制御の実行を解除(停止又は中止)する旨のコマンドを監視端末40等の他の装置より受信した場合には、低減制御を解除する。これにより、低減制御の実行及び解除を任意に決定することが可能となっている。
本実施形態においては、通信品質判定部343は、所定期間における通信品質の計測結果に基づいて決定される通信品質の基準値SVに基づき、通信品質を判定する。これにより、通信品質の低下の度合いを高精度に判定することが可能となっている。
本実施形態では、低減制御のための基準値SVについて、監視端末40等の他の情報処理装置によって決定可能である。これにより、低減制御の契機を任意に適宜設定することが可能となっている。
第1実施形態に係る内容は、以下の変形例に示すように適宜変形が可能である。なお、各変形例は、矛盾が生じない範囲で他の変形例と組み合わせて適用されてもよい。
低減制御の基準値SVは、主として、監視端末40により設定されるようにしてもよい。このような構成により、監視端末40を操作する監視者等の意向を反映した機器管理システム1を提供できる。例えば、機器管理システム1において、通信量に応じて通信料金が請求される場合、監視端末40を操作する監視者等が、自己のニーズに応じた通信量に設定することができる。これにより、監視端末40を操作する監視者等の通信料金を抑えることができる。
本実施形態に係る機器管理システム1は、低減制御を実行する際に、監視端末40を操作する監視者等による承諾を得る構成であってもよい。具体的には、低減制御の実行が決定に関して、監視端末40において低減制御通知の受信に応じて、低減制御の実行を承諾するか否かの選択を監視者に行わせるようにしてもよい。そして、監視端末40において、低減制御の実行を承諾することが選択された場合、監視端末40から管理装置30に、低減制御の実行を承諾することを示す「承諾通知」が送信され、管理装置30では、監視端末40から承諾通知を受信した場合に低減制御の実行を決定するようにしてもよい。なお、所定の時間内に監視端末40からの承諾通知が受信されない場合、管理装置30が低減制御を実行しないことを決定するようにしてもよい。
上記説明では、通信条件を変更し、複数の状態情報(機器情報)の一部の通信を抑制する、又は通信頻度を変更することで、低減制御を実行するものであるが、本実施形態に係る低減制御はこのような内容に限定されるものではない。本実施形態に係る低減制御は、通信ネットワークNW1を介した管理装置30及び制御端末20間の通信に関して通信品質の低下を抑制又は改善する任意の制御により実現されるものである。
なお、本実施形態に係る機器管理システム1では、低減制御は、通信品質の低下の度合いに応じて多段階的に強弱を付けてもよい。そして、このような機器管理システム1では、送信するデータ項目が100個あるとすると、低減制御が実行されない場合(「不要」の場合)は100項目が送信されることになる。一方、このような機器管理システム1では、通信品質が「少し低下」している場合は80項目が送信され、「さらに低下」している場合は50項目が送信され、「著しく低下」している場合は20項目が送信されるように低減制御が実行される。
管理装置30の処理部34における通信品質測定部342、通信品質判定部343、低減制御部344のいずれかについては、処理結果が管理装置30に適宜送信される限り、他の装置に含まれていてもよい。例えば、通信品質測定部342、通信品質判定部343、低減制御部344のいずれかについては、処理結果が管理装置30に適宜送信される限り、監視端末40に含まれていてもよい。
上記実施形態においては、機器情報は空気調和機10に関するものであるが、機器情報は空気調和機10以外の機器(例えば換気装置、調湿装置、エアハンドリングユニット、チラーユニット、及び/又はその他の冷凍装置等)に関するものであってもよい。
上記実施形態においては、低減制御においては、管理装置30及び制御端末20間における通信に関する通信条件が変更されている。より具体的に、上記実施形態に係る低減制御においては、管理装置30から制御端末20へ送られる情報に関する通信条件、及び制御端末20から管理装置30へ送られる情報に関する通信条件の双方が変更されうるようになっている。しかし、低減制御は、管理装置30から制御端末20へ送られる情報に関する通信条件、及び制御端末20から管理装置30へ送られる情報に関する通信条件の一方のみを変更するものであってもよい。
図4に示される各通信条件は、あくまでも例示である。通信条件については、設計仕様や使用環境に応じて適宜変更されうる。例えば、管理装置30から制御端末20へ送られる情報に関しても、優先度に応じて、通信条件が適宜変更されうる。
図5に示される優先度の決定において考慮される事項は、あくまでも例示である。優先度の決定において考慮される事項は、設計仕様や使用環境に応じて適宜変更されうる。
図6-図9に示される優先度の決定態様については、あくまでも例示である。優先度の決定態様については、設計仕様や使用環境に応じて適宜変更されうる。
図10に示される処理の流れについては、あくまでも例示である。管理装置30、制御端末20及び監視端末40の処理の流れについては、設計仕様や使用環境に応じて適宜変更されうる。
図1に示される機器管理システム1の構成態様については、適宜変更が可能である。例えば、いずれか又は全ての制御端末20については、空気調和機10に内蔵されていてもよい。具体的に、いずれか又は全ての制御端末20は、いずれかの室外機11に内蔵されていてもよい。また例えば、いずれか又は全ての制御端末20は、いずれかの室内機12に内蔵されていてもよい。また、制御端末20が通信ネットワークNW1にアクセスするためのルータ等の通信装置については、制御端末20とともに空気調和機10に内蔵されてもよいし、独立して配置されてもよい。また、制御端末20を内蔵する空気調和機10と、内蔵しない空気調和機10と、が混在していてもよい。
以下、本開示の第2実施形態に係る機器管理システム1Aについて説明する。なお、以下の実施形態は、具体例であって、技術的範囲を限定するものではなく、趣旨を逸脱しない範囲で適宜変更可能である。第1実施形態に係る機器管理システム1との相違部分について主に説明する。以下において説明を省略している部分については、原則として機器管理システム1におけるのと共通である。
