Abstract
Description
図1は、本実施の形態に係る空気調和システム100の概要構成例図である。図2Aは、第1の制御部4の構成例を説明するブロック図である。図2Bは、第2の制御部24の構成例を説明するブロック図である。図1、図2A及び図2Bを参照して空気調和システム100の構成などについて説明する。
空気調和システム100は、冷凍サイクル装置50を制御する集中コントローラ20及び冷凍サイクル装置60を制御する集中コントローラ31と、集中コントローラ20及び集中コントローラ31を統括制御する集中管理装置1とを有しているものである。なお、各図では、集中管理装置1は親機として、集中コントローラ20及び集中コントローラ31は子機として表記されている。
集中管理装置1は、2台の集中コントローラ20及び集中コントローラ31と、各種データのやりとりをする外部操作端末80とに通信自在に接続されているものである。集中管理装置1は、子機である集中コントローラ20及び集中コントローラ31を統括制御するものであり、これらの親機に対応する構成である。
また、集中管理装置1は、各種構成を制御する第1の制御部4と、ユーザー及び管理人などに操作される第1の操作部5と、ユーザー及び管理人などのために予め設定された情報などを表示する第1の表示部6と、集中コントローラ20及び集中コントローラ20との間でデータを出力をするときに同期をするのに利用される第1のデータ同期部7とを有している。
また、第1のデータ部9に格納されたデータは、子機である集中コントローラ20及び集中コントローラ31の有する第4のデータ部29にて格納され、親機側のデータのバックアップがなされる。
集中コントローラ20は、冷凍サイクル装置50と通信してこれらを制御するのに利用される第2の専用通信部21と、集中管理装置1などと通信するのに利用される第2のLAN通信部23とを有しているものである。
集中コントローラ20は、各種構成を制御する第2の制御部24と、ユーザー及び管理人などに操作される第2の操作部25と、ユーザー及び管理人などのために予め設定された情報などを表示する第2の表示部26と、集中管理装置1との間でデータ出力をするときに同期をするのに利用される第2のデータ同期部27とを有している。
図3Aは、本実施の形態に係る空気調和システム100において、集中管理装置1と集中コントローラ20とでデータの二重化をするときの動作の流れの一例を説明するフローチャートである。図3Bは、集中コントローラ20側から集中管理装置1側へデータが出力され、按分計算部10で按分計算が実施される様子を説明する図である。図3Cは、按分計算の結果が第1のデータ部9及び第2のデータ部8に格納され、その後集中管理装置1側から集中コントローラ20側へデータが出力される様子を説明する図である。なお、説明の便宜上のため、図3A~図3Cでは、集中コントローラ31については集中管理装置1とデータのやり取りをせず、集中コントローラ20のみが集中管理装置1とデータのやりとりをしている様子を示している。
図4Aは、空気調和システム100の集中コントローラ31を交換したときに、新たに設置する集中コントローラ31に対してデータの復元をする様子を説明する模式図である。図4A及び前述した図1及び図2を参照して、データ復元の手段について説明する。図4Aに示すように、集中コントローラ31が故障などして、新しいものに交換している。
また、各集中コントローラは、第3のデータ部28に格納され、第1の識別番号データと比較される第2の識別番号データを有している。第2の識別番号データは、各集中コントローラの識別番号及び親機である集中管理装置1の識別番号を有している。ここで、新しい集中コントローラ31には、識別番号がない(たとえば、識別番号000など)。
集中管理装置1は、二重化を実施しているとき及び按分計算を実施しているときには、第1の専用通信部2を通じた各集中コントローラの冷凍サイクル装置60との通信を無効とするように構成されている。二重化の動作及び按分計算の動作は、集中管理装置1の各種回路にかかる負担が増大している。そこで、二重化の動作及び按分計算を実施しているときには、第1の制御部4の第1の専用通信部制御手段4Aは、第1の専用通信部2と冷凍サイクル装置60との通信が無効となるように、第1の専用通信部2を制御する。これにより、集中管理装置1は、より円滑に二重化の動作及び按分計算の動作を実施することができる。
外部操作端末80は、集中管理装置1及び各集中コントローラに通信自在に接続されているものである。外部操作端末80は、たとえば、パーソナルコンピュータなどで構成することができる。集中管理装置1及び各集中コントローラは、外部操作端末80の有するデータによって、集中管理装置1及び各集中コントローラのうちの少なくとも一方のデータが変更されたときは、二重化を実施する。これにより、第1のデータ部9のデータとバックアップ用のデータが格納される第4のデータ部29のデータとが異なる期間、及び第3のデータ部28のデータとバックアップ用のデータが格納される第2のデータ部8のデータとが異なる期間を短くすることができ、バックアップデータの信頼性を向上させることができる。
本実施の形態に係る空気調和システム100は、集中管理装置1が第1のデータ部9及び各集中コントローラのバックアップ用の第2のデータ部8を有するとともに、各集中コントローラが第3のデータ部及び集中管理装置1のバックアップ用の第4のデータ部29を有する。たとえば、集中管理装置1及び各集中コントローラのうちのいずれかを交換したとしても、新しく交換したものにデータを復元することができる。これにより、たとえば、空気調和システム100が消費電力に基づいて課金をする態様のものである場合において、ユーザーに課金することができなくなって利便性が損なわれてしまうことを回避することができる。
図5は、第2の制御部240がフラグ設定手段24F及びフラグ判定手段24C1を有する態様についての説明図である。各集中コントローラは、第3のデータ部28に格納される運転データが修正されたときにフラグを立て、第3のデータ部28に格納された運転データのうちフラグを立てた運転データを第2のデータ部8に出力するように構成されていてもよい。すなわち、各集中コントローラの第2の制御部240は、第3のデータ部28に格納される運転データが修正されたときにフラグを立てるフラグ設定手段24Fを有していてもよい。また、第2のデータ同期部制御手段24Cが第3のデータ部28に格納された運転データのうちフラグを立てた運転データを第2のデータ部に出力するフラグ判定手段24C1を有していてもよい。フラグ設定手段24F及びフラグ判定手段24C1を有すると、データの二重化時に第3のデータ部28に格納されたデータの全てを第2のデータ部8に転送することを回避することができ、データ転送量の増大を抑制することができる。
