Description
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。また、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。また、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「空調機」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の管理対象は空調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は空調機10の室外機11の室外機制御回路11Xに接続することで空調機10を制御するものである。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、を備える。なお、図3では、便宜上、制御端末20aの各構成の添え字を省略している。
管理装置30は、制御端末20及び監視端末40のそれぞれにネットワークを介して接続し、複数の空調機10a~10iの運転状態等を管理する。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に属する空調機10(機器)に関連する各種「要求」を管理装置30に送信する。また、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、空調機10の状態を監視する。監視端末40は、例えば、空調機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、空調機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調機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5は本実施形態に係る機器管理システム1における低減制御を説明するためのシーケンス図である。
(5-1)
以上説明したように、本実施形態に係る機器管理システム1は、1以上の空調機(機器)10a~10iを関連付けて制御し、空調機に関連する状態情報(機器情報)を送信する制御端末20a~20cと、空調機10a~10iに関連する要求を送信するとともに機器の状態を監視する監視端末40a~40cと、のそれぞれにネットワークを介して接続する管理装置30とを備える。ここで、管理装置30は、通信部33(受信部)と、処理部34とを有する。通信部33は、監視端末40からの要求及び機器情報を受信する。処理部34は、管理装置30における各種情報処理を実行する。
また、本実施形態に係る管理装置30は、低減制御部344が、演算部341による演算の負荷が閾値を超えたと判定された場合、制御端末20との間の通信条件を変更することにより負荷を低減する。ここで、制御端末20は、空調機10に関連する複数種類の状態情報(機器情報)を送信するものである。そして、制御端末20は、情報処理の負荷が閾値を超えた場合、複数種類の状態情報の一部の通信を抑制する。
また、本実施形態に係る管理装置30は、閾値を設定するための入力部32(閾値設定部)をさらに備える。これにより、管理装置30を操作する管理者が、機器管理システム1全体の通信に基づく管理装置30の負荷を調整することができる。
また、本実施形態に係る管理装置30は、低減制御部344が、負荷判定部343により負荷が閾値を超えたと判定された場合、低減制御を実行する旨を示す低減制御通知を制御端末20に送信する。これにより、制御端末20で低減制御を実行できるようになる。要するに、低減制御が、管理装置30と制御端末20との間の通信条件を変更する制御である場合には、処理部34の負荷が低減するように、制御端末20の通信条件を変更することができる。
また、本実施形態に係る管理装置30では、負荷判定部343が、演算部341による演算の負荷が閾値を超えたと判定した後、負荷が閾値を下回ったか否かを随時判定する。そして、負荷判定部343により負荷が閾値を下回ったと判定された場合、低減制御部344が、低減制御を解除する旨の解除通知を制御端末20に送信する。このような構成により、管理装置30は、機器管理システム1全体に対する負荷が高くないときには、低減制御を解除することができる。
また、本実施形態に係る管理装置30では、負荷判定部343により演算部341による演算の負荷が閾値を超えたと判定された場合、低減制御部344が、低減制御を実行する旨を示す低減制御通知を監視端末40に送信する。そして、低減制御部344は、低減制御通知の送信に応じて低減制御の実行を承諾する旨を示す承諾通知を監視端末40から受信したときに低減制御を実行する。
また、本実施形態に係る管理装置30は、負荷検出部342が、メモリ使用量、CPU負荷、ネットワーク負荷、及び外部システムからのアクセス量のいずれか1つ又は任意の組み合わせに基づいて、演算部341における演算の負荷を検出する。したがって、これらの情報に基づく負荷に対して、管理装置30は、スペックを増加させずに、負荷ピークに耐えることができる。
また、本実施形態に係る管理装置30は、複数種類の状態情報(機器情報)のうち通信を抑制する状態情報(機器情報)を、空調機10a~10i毎に関連付けて記憶する通信条件データベース31Dを備えるものである。管理装置30は、このような通信条件データベース31Dを用いることにより、低減制御の内容を決定することができる。
(6-1)変形例A
上記説明においては、管理装置30において低減制御の閾値が入力される構成としたが、本実施形態に係る機器管理システム1の構成はこれに限るものではない。具体的には、低減制御の閾値は監視端末40により設定されてもよい。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に請求される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、図7に示すように、管理装置30が低減制御の実行を決定する際に、管理装置30から監視端末40に「低減制御通知」を送信する(V4-Yes)。これにより、監視端末40では、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が可能になる(V6)。そして、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」が送信される(V6-Yes)。そして、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、低減制御の実行を決定する(V7)。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低減制御を実行しないことを決定する。具体的には、管理装置30は、演算部341による演算の負荷が閾値を超えてないとみなして処理を継続する(V4-No)。
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ことで、低減制御を実行するものであったが、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。すなわち、本実施形態に係る低減制御は、管理装置30の演算部341による情報処理の演算の負荷を低減する任意の制御により実現されるものである。
なお、上記機器管理システム1において、管理装置30の演算部341による負荷が所定期間にわたって低い場合、管理装置30はスケールダウンの提案を促す提案機能を具備していてもよい。さらに、提案機能は、管理装置30の演算部341による負荷が所定期間にわたって高い場合、管理装置30はスケールアップとスケールアウトの提案を促すものでもよい。さらに、提案機能は、これらの提案をする際に、それに伴う料金情報を付加するものでもよい。
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、演算部341の負荷の逼迫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、逼迫度が「少し逼迫」している場合は80項目が送信され、「逼迫」している場合は50項目が送信され、「かなり逼迫」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。
上述した実施形態及び変形例に係る機器管理システム1の応用例を以下に示す。ここでは、機器管理システム1は、演算部341の負荷を示す「負荷レベル」に応じて多段階の低減制御を実行する。すなわち、負荷の程度に応じた複数の閾値が設定されており、それにより負荷レベルが定義される。また、ここでいう、負荷レベルは、上記変形例Eにおける「逼迫度合い」を包含する概念である。そして、機器管理システム1は、負荷レベルと優先度とに応じて機器情報の通信条件を変更する。
以下の説明においては、他の応用例との区別のために、機器管理システム1の符号に英大文字Xを付して説明する。
以下の説明においては、他の応用例との区別のために、機器管理システム1の符号に英大文字Yを付して説明する。
以下の説明においては、他の応用例との区別のために、機器管理システム1の符号に英大文字Zを付して説明する。
第4応用例の機器管理システム1では、管理装置30が、制御端末20から受信した機器情報に基づいて、監視端末40に表示する監視情報を提供する。そして、管理装置30は、負荷レベルの判定がされた場合、機器10の優先度に応じて監視情報の表示項目を制限する。なお、監視情報の表示項目は監視端末40の種類に応じて異なる。例えば、監視端末40は、ビル管理者、データ分析者、エンドユーザ等により利用され、利用者毎に利用するアプリケーションが異なるものである。そこで、第4応用例の機器管理システム1では、利用者の種類等及び負荷レベルの判定に応じて、監視情報の表示項目を制限することで管理装置30における演算負荷を低減する。例えば、機器管理システム1は、監視端末40からの要求があったとしても、グラフィカルユーザインタフェース(GUI)等の処理負荷の高いアプリケーションを一時的に使用不可にしたり、GUIでのログインを制限したりする等の処理を実行することで、管理装置30における演算負荷を低減する。
第5応用例の機器管理システム1では、管理装置30と制御端末20との間の通信条件を変更する以外の低減制御を実行する。
本実施形態に係る機器管理システムは、上述した全ての内容を組み合わせて構成することができるものである。さらに、以下の特徴を有するものである。
