Abstract
Description
<1.実施の形態の概要>
図1は、第1の実施の形態に係る電力管理システム1を示す図である。図1の電力管理システム1は、HEMS(home energy management system)コントローラ10を含む。また、電力管理システム1は、電力情報管理装置の一例である通信端末100を含む。図1において、家電機器14~17は、交流電源11からの交流電力によっても、直流電源12,13からの直流電力によっても、動作する。そして、家電機器14~17は、状況に応じて、たとえばHEMSコントローラ10から、いずれの電源からの電力によって動作するかを制御される。
図1の電力管理システム1の構成を説明する。
図3は、HEMSコントローラ10の構成を示すブロック図である。
図4は、HEMSコントローラ10の記憶部704に格納されている動作情報710のデータ構造の一例を示す図である。
図6は、HEMSコントローラ10の記憶部704に格納されている切替情報720のデータ構造の一例を示す図である。
図8は、家電機器14のハードウェア構成の一例を概略的に示す図である。図8に示されるように、家電機器14は、制御部900と、アンテナ901と、無線通信部902と、機能実行部903と、動作記憶部904とを備える。
無線通信部902は、通信インターフェースの一例である。制御部900は、無線通信部902およびアンテナ901を利用して、ネットワーク600(図1参照)に接続して、HEMSコントローラ10等の他の機器と通信する。なお、家電機器14は、無線LAN規格、Bluetooth(登録商標)などの近距離無線通信の規格に対応している場合もあり得る。当該通信規格に従って、家電機器14は、HEMSコントローラ10等の他の機器と直接通信する場合もあり得る。
図9は、第1の実施の形態の通信端末100の構成を示すブロック図である。
図10は、通信端末100において、家電機器14~17における、直流電力の消費の量に関する情報を表示するために実行される処理のフローチャートである。当該処理は、たとえば、通信端末100にインストールされた電力管理用のアプリケーションによって実現される。
図12および図13は、電力の消費の量に関する情報の表示画面の変形例を示す図である。図12の画面520は、所定期間(表示対象の期間)が24時間である場合に対応している。画面520は、グラフ521を含む。グラフ521では、一定期間(15分)ごとにグラフの色が特定される。グラフ521の縦軸は電力の消費量であり、横軸は時間である。上記一定期間は、家電機器14~17のそれぞれがHEMSコントローラ10に「状態通知」(図5参照)を送信する時間間隔と同じまたは当該時間間隔に多少の余裕が加えられた時間とされてもよい。
以上説明された第1の実施の形態では、家電機器14~17によって、交流電力と直流電力との間で駆動するための電力を切り替えて動作する負荷機器が構成される。そして、通信端末100は、主に図10を参照して説明されたように、家電機器14~17のうち表示対象として指定された家電機器について、直流電力の消費の量に関する情報についての、表示用の画像データ(表示情報)を生成する。
以上説明された第1の実施の形態の電力管理システム1において、直流電源12,13から供給される直流電力を消費することは、ユーザにおいて、商用の交流電源11から供給される直流電力を消費することに対し、以下の利点をもたらすと言える。
第2の実施の形態の電力管理システム1のハードウェア構成は、第1の実施の形態のものと同じとすることができる。なお、第2の実施の形態の電力管理システム1において、通信端末100は、第1の実施の形態と比較して、図10のステップS50の制御を省略する。つまり、第2の実施の形態では、表示対象となった家電機器についての直流電力の消費の量に関する情報のみが表示される。
第3の実施の形態の電力管理システム1のハードウェア構成は、第1の実施の形態のものと同じとすることができる。ただし、第3の実施の形態では、通信端末100は、直流電力の消費量についての目標値の入力を受け付ける。そして、通信端末100は、図2等に示されたような家電機器の消費電力に関する情報の表示において、直流電力の消費量が上記目標値を達成できたか否か、つまり、当該消費量が目標値以上となったか否かを、表示する。
第4の実施の形態の電力管理システム1のハードウェア構成は、第3の実施の形態のものと同じとすることができる。また、第4の実施の形態では、通信端末100の制御部160は、さらに、記憶部150に格納された目標値を変更する情報の入力を受け付ける。
第5の実施の形態の電力管理システム1では、図2の画面510等の、家電機器の電力消費についての表示用の画像データは、HEMSコントローラ10において生成される。つまり、第5の実施の形態では、HEMSコントローラ10が電力情報管理装置の一例である。通信端末100は、電力消費の表示の指示を受けると、HEMSコントローラ10に、表示用の画像データの生成をリクエストする。
第6の実施の形態として、電力管理システム1における動作情報および切替情報の管理態様の変形例が示される。第1の実施の形態において動作情報と切替情報とが個別に管理されていたのに対し、第6の実施の形態では、動作情報と切替情報に相当する情報が「電力消費情報」として管理される。
図21は、電力消費情報の内容の一例を模式的に示す図である。
通知時刻1002は、各家電機器から「状態通知」(図5参照)を受けた時刻を示す。つまり、HEMSコントローラ10は、電力消費情報1000内の各レコードを、たとえば、図5を参照して説明された、家電機器14~17のそれぞれからの「状態通知」において取得する。そして、通知時刻1002は、「状態通知」を当該「状態通知」を受けた時刻である。
図22は、第6の実施の形態のHEMSコントローラ10の構成を示す図である。
図23は、第6の実施の形態の通信端末100の構成を示すブロック図である。
式(1)において、「43000(Wh)」は、「エアコン(1)」の2015年5月5日の13時15分のDC積算電力消費量である。「42000(Wh)」は、「エアコン(1)」の2015年5月5日の13時00分のDC積算電力消費量である。
第7の実施の形態の電力管理システムは、複数の家電機器を含む。当該複数の家電機器には、交流電力を動力源とする家電機器と直流電力を動力源とする家電機器が含まれる。当該複数の家電機器は、交流電力のみを駆動源とするもの、直流電力のみを駆動源とするもの、および、交流電力と直流電力のいずれも駆動源とするものを含み得る。つまり、第7の実施の形態の電力管理システムは、交流電力および直流電力よって動作する、複数の家電機器を含む。
