Other features and advantages of the present invention will be better understood with reference to the following detailed description and accompanying drawings.
It is a block diagram which shows the principal part of the energy management system using the management apparatus which concerns on Embodiment 1 of this invention. It is a system configuration figure showing an energy management system using a management device concerning Embodiment 1 of the present invention. It is explanatory drawing which shows the operation example of the energy management system using the management apparatus which concerns on Embodiment 1 of this invention.
　（実施形態１）
　本実施形態の管理装置は、エネルギーの使用状況をユーザに通知するエネルギー管理システムに用いられる。以下では、エネルギー管理システムが一般住宅に用いられており、管理対象のエネルギーが電力（電気エネルギー）である場合を例として説明する。 (Embodiment 1)
The management apparatus according to the present embodiment is used in an energy management system that notifies a user of energy usage. Below, the case where the energy management system is used for a general house and the energy to be managed is electric power (electric energy) will be described as an example.
　このエネルギー管理システム１は、図２に示すように、管理装置２と、テレビ受像機（以下、「テレビ」と略称する）３とを備えている。管理装置２は、エネルギー（ここでは電力）の使用状況に関する情報を使用情報として、当該使用情報に基づいて生成したコンテンツをテレビ３に表示させる。 The energy management system 1 includes a management device 2 and a television receiver (hereinafter abbreviated as “TV”) 3 as shown in FIG. The management device 2 displays information generated on the basis of the usage information on the television 3 as information on the usage status of energy (here, electric power).
　図２では、商用電源の単相三線式の引込線１１～１３に接続された分電盤４が設けられ、分電盤４には、引込線１１～１３が接続される主幹ブレーカ４１と、主幹ブレーカ４１の二次側から分岐する複数の電路の各々に挿入される分岐ブレーカ４２とが設けられている。各分岐ブレーカ４２の二次側には負荷５が接続される。ここでいう負荷５には、屋内配線に接続される種々の電気機器の他、コンセント、壁スイッチ等の配線器具を含む。 In FIG. 2, a distribution board 4 connected to single-phase three-wire service lines 11 to 13 of a commercial power supply is provided. The distribution panel 4 includes a main breaker 41 to which the service lines 11 to 13 are connected, and a main circuit breaker. A branch breaker 42 is provided that is inserted into each of a plurality of electrical paths branched from the secondary side of 41. A load 5 is connected to the secondary side of each branch breaker 42. The load 5 here includes various electrical devices connected to the indoor wiring, as well as wiring devices such as an outlet and a wall switch.
　さらに、図２の例では、住宅に太陽電池６が設けられており、太陽電池６と電力会社から供給される商用電力系統とで系統連系が行われる。太陽電池６は、インバータ回路（図示せず）を有するパワーコンディショナ７に接続されている。パワーコンディショナ７は、太陽電池６で生成された直流電力をインバータ回路にて交流電力に変換して出力する。パワーコンディショナ７には蓄電池８も接続されており、パワーコンディショナ７は蓄電池８の充電および放電を行う。つまり、パワーコンディショナ７は、たとえば昼間に太陽電池６の出力によって蓄電池８を充電し、夜間には蓄電池８に蓄積された電力をインバータ回路にて交流電力に変換して出力する。 Furthermore, in the example of FIG. 2, the solar cell 6 is provided in the house, and the grid connection is performed between the solar cell 6 and the commercial power system supplied from the electric power company. The solar cell 6 is connected to a power conditioner 7 having an inverter circuit (not shown). The power conditioner 7 converts the DC power generated by the solar cell 6 into AC power by an inverter circuit and outputs the AC power. A storage battery 8 is also connected to the power conditioner 7, and the power conditioner 7 charges and discharges the storage battery 8. That is, the power conditioner 7 charges the storage battery 8 by the output of the solar cell 6 in the daytime, for example, and converts the power stored in the storage battery 8 into AC power by the inverter circuit and outputs it at night.
　パワーコンディショナ７は、分電盤４に設けられている連系ブレーカ４３に接続される。連系ブレーカ４３の二次側は主幹ブレーカ４１の二次側に接続されている。これにより、太陽電池６および蓄電池８の出力は、パワーコンディショナ７を介して分電盤４から負荷５に供給される。負荷５で消費される電力を太陽電池６および蓄電池８の出力のみで賄えない場合には、商用電力系統から負荷５へ電力供給される。また、太陽電池６で生成される電力が全ての負荷５で消費される電力の合計よりも大きい場合で、且つ蓄電池８が満充電状態にあれば、太陽電池６で生じた電力の余剰分（以下、「余剰電力」という）は、商用電力系統に逆潮流されて電力会社に売電される。つまり、余剰電力の発生時、パワーコンディショナ７は、余剰電力の電圧を商用電力系統よりも高くすることによって逆潮流を行う。 The power conditioner 7 is connected to an interconnection breaker 43 provided on the distribution board 4. The secondary side of the interconnection breaker 43 is connected to the secondary side of the main breaker 41. Thereby, the output of the solar cell 6 and the storage battery 8 is supplied from the distribution board 4 to the load 5 via the power conditioner 7. When the power consumed by the load 5 cannot be covered only by the outputs of the solar battery 6 and the storage battery 8, power is supplied from the commercial power system to the load 5. Further, if the power generated by the solar cell 6 is larger than the total power consumed by all the loads 5 and the storage battery 8 is in a fully charged state, the surplus power generated by the solar cell 6 ( Hereinafter, the “surplus power”) flows backward to the commercial power system and is sold to the power company. That is, when surplus power is generated, the power conditioner 7 performs reverse power flow by setting the surplus power voltage higher than that of the commercial power system.
　なお、このように系統連系を行う住宅においては、商用電力系統の停電時に太陽電池６の単独運転を防止する必要がある。そこで、パワーコンディショナ７には、商用電力系統の停電検出時にインバータ回路の動作を停止させるとともに、連系ブレーカ４３を解列（開放）させる保護機能が設けられている。 In addition, in the house which performs grid connection in this way, it is necessary to prevent the independent operation of the solar cell 6 at the time of a power failure in the commercial power system. Accordingly, the power conditioner 7 is provided with a protection function for stopping the operation of the inverter circuit when the power failure of the commercial power system is detected and disconnecting (opening) the interconnection breaker 43.
　また、分電盤４には、主幹ブレーカ４１を流れる電流を検出するセンサ部４４と、センサ部４４の出力を受けて、負荷５へ供給されている電力量を計測する計測器４５とが設けられている。計測器４５は、主幹ブレーカ４１を介して負荷５へ供給される電力の積算値を求め、当該積算値を電力量として計測する。センサ部４４は主幹ブレーカ４１の二次側（分岐ブレーカ４２側）に挿入され、計測器４５は他の内器（主幹ブレーカ４１や分岐ブレーカ４２）と一緒に分電盤４内に収納されている。また、センサ部４４は分岐ブレーカ４２ごとに設けられていてもよく、この場合、計測器４５はセンサ部４４の出力から負荷５ごとに電力量を計測する構成であってもよい。 Further, the distribution board 4 is provided with a sensor unit 44 that detects a current flowing through the main breaker 41 and a measuring device 45 that receives the output of the sensor unit 44 and measures the amount of power supplied to the load 5. It has been. The measuring device 45 obtains an integrated value of the electric power supplied to the load 5 via the main breaker 41 and measures the integrated value as an electric energy. The sensor unit 44 is inserted into the secondary side (branch breaker 42 side) of the main breaker 41, and the measuring instrument 45 is housed in the distribution board 4 together with other internal devices (the main breaker 41 and the branch breaker 42). Yes. Further, the sensor unit 44 may be provided for each branch breaker 42, and in this case, the measuring device 45 may be configured to measure the electric energy for each load 5 from the output of the sensor unit 44.
　さらに、パワーコンディショナ７は、太陽電池６で発電された電力量（発電量）を計測する発電量計測部７１（図１参照）を有し、蓄電池８は、残りの電力量（残容量）を計測する残容量計測部８１（図１参照）を有している。これら発電量計測部７１と残容量計測部８１と計測器４５との各々は、エネルギーの使用状況を計測し使用情報を管理装置２に提供する計測装置を構成する。 Furthermore, the power conditioner 7 has a power generation amount measuring unit 71 (see FIG. 1) that measures the amount of power generated by the solar cell 6 (power generation amount), and the storage battery 8 has a remaining power amount (remaining capacity). The remaining capacity measuring unit 81 (see FIG. 1) is measured. Each of the power generation amount measuring unit 71, the remaining capacity measuring unit 81, and the measuring device 45 constitutes a measuring device that measures the usage status of energy and provides usage information to the management device 2.
　管理装置２は、図１に示すように、コンテンツをテレビ３に表示させる処理を行う処理部２１と、各種のデータを記憶する記憶部２２とを有している。 As shown in FIG. 1, the management device 2 includes a processing unit 21 that performs processing for displaying content on the television 3 and a storage unit 22 that stores various data.
　処理部２１は、後述の生成部２６にて生成されるコンテンツをテレビ３に提供することによって、コンテンツをテレビ３に表示させる。具体的には、処理部２１がコンテンツを提供するＷｅｂサーバとしての機能を有し、テレビ３が処理部２１から提供されるコンテンツを閲覧するＷｅｂブラウザとして機能を有している。処理部２１は、テレビ３からコンテンツ要求を受けると、コンテンツ要求の送信元のテレビ３に対して、コンテンツ要求への応答としてコンテンツを提供する。 The processing unit 21 displays the content on the television 3 by providing the television 3 with the content generated by the generation unit 26 described later. Specifically, the processing unit 21 functions as a Web server that provides content, and the TV 3 functions as a Web browser that browses content provided from the processing unit 21. When receiving the content request from the television 3, the processing unit 21 provides the content as a response to the content request to the television 3 that has transmitted the content request.
　テレビ３は、管理装置２から提供されたコンテンツを画面の一部（たとえば右下の隅）に表示する。具体的には、テレビ３はテレビジョン放送を受信して表示する映像の一部に重なるようにコンテンツを表示する。なお、コンテンツの表示形態は上記形態に限らず、たとえばテレビジョン放送を受信して表示する映像を縮小し、この映像と並べてコンテンツが表示される形態であってもよい。あるいは、一時的にテレビジョン放送の表示を中断して、全画面にコンテンツが表示されてもよい。 The television 3 displays the content provided from the management device 2 on a part of the screen (for example, the lower right corner). Specifically, the television 3 displays the content so as to overlap a part of the video to be received and displayed. In addition, the display form of the content is not limited to the above form, and for example, a form in which a television broadcast is received and displayed and the content is displayed along with the video may be displayed. Alternatively, the television broadcast display may be temporarily interrupted, and the content may be displayed on the entire screen.
　また、管理装置２は、計測器４５と発電量計測部７１と残容量計測部８１との各々の計測結果（電力量）を、エネルギーの使用状況に関する使用情報として取得し、取得した使用情報を記憶部２２に記憶する情報取得部２０を有している。ここでは、計測器４５に接続される第１の計測インタフェース２３と、発電量計測部７１に接続される第２の計測インタフェース２４と、残容量計測部８１に接続される第３の計測インタフェース２５とが管理装置２に設けられている。情報取得部２０は、これら第１～第３の各計測インタフェース２３～２５に接続されている。 Moreover, the management apparatus 2 acquires each measurement result (electric power amount) of the measuring instrument 45, the power generation amount measuring unit 71, and the remaining capacity measuring unit 81 as usage information regarding the usage state of energy, and the acquired usage information is obtained. The information acquisition unit 20 is stored in the storage unit 22. Here, the first measurement interface 23 connected to the measuring instrument 45, the second measurement interface 24 connected to the power generation amount measurement unit 71, and the third measurement interface 25 connected to the remaining capacity measurement unit 81. Are provided in the management apparatus 2. The information acquisition unit 20 is connected to each of the first to third measurement interfaces 23 to 25.
　ここで、情報取得部２０は、定期的（たとえば５分ごと）に使用情報を取得し、取得した使用情報を時系列に従って記憶部２２に記憶する。なお、情報取得部２０が定期的に取得する使用情報は、発電量計測部７１と残容量計測部８１と計測器４５との各々で、前回の取得時点から今回の取得時点までの間に計測された電力量である。 Here, the information acquisition unit 20 acquires the usage information periodically (for example, every 5 minutes), and stores the acquired usage information in the storage unit 22 in time series. Note that the usage information periodically acquired by the information acquisition unit 20 is measured by the power generation amount measurement unit 71, the remaining capacity measurement unit 81, and the measuring instrument 45 between the previous acquisition time and the current acquisition time. Power amount.
　また、管理装置２は、コンテンツを生成する生成部２６と、テレビ３のオンオフの別を検知する動作検知部２７と、テレビ３がオンしたタイミングに関する条件情報を取得する条件取得部２８と、テレビ３に接続されるテレビ用インタフェース２９とを有している。テレビ用インタフェース２９はテレビ通信部を構成する。 In addition, the management device 2 includes a generation unit 26 that generates content, an operation detection unit 27 that detects whether the television 3 is on or off, a condition acquisition unit 28 that acquires condition information regarding the timing when the television 3 is turned on, 3 is connected to the TV interface 29. The television interface 29 constitutes a television communication unit.
　本実施形態では、管理装置２は、テレビ３、パワーコンディショナ７の発電量計測部７１、蓄電池８の残容量計測部８１、計測器４５と共に、住宅内において汎用の通信プロトコルを利用したＬＡＮ（Local Area Network）を構築する。テレビ３と管理装置（テレビ用インタフェース２９）２との間、並びにパワーコンディショナ７、蓄電池８、計測器４５の各々と管理装置２との間は、ＬＡＮケーブルによって有線接続されていてもよいし、無線ＬＡＮによって無線接続されていてもよい。なお、これらの接続形態はＬＡＮ接続に限らず、たとえばテレビ３と管理装置（テレビ用インタフェース２９）２との間はＨＤＭＩ（High-Definition MultimediaInterface）等の規格に準じた接続形態であってもよい。 In the present embodiment, the management device 2 includes a television 3, a power generation amount measuring unit 71 of the power conditioner 7, a remaining capacity measuring unit 81 of the storage battery 8, and a measuring device 45, and a LAN ( Build Local Area Network). The TV 3 and the management apparatus (TV interface 29) 2 and the power conditioner 7, the storage battery 8, and the measuring instrument 45 and the management apparatus 2 may be connected by a wired LAN cable. The wireless connection may be established by a wireless LAN. Note that these connection forms are not limited to LAN connections, and for example, connection forms conforming to standards such as HDMI (High-Definition Multimedia Interface) may be used between the television 3 and the management device (television interface 29) 2. .
　生成部２６は、記憶部２２に記憶されている使用情報に基づいて、処理部２１よりテレビ３に提供するコンテンツを生成する。生成部２６は、情報取得部２０が使用情報を取得する度に新しいコンテンツを生成し、この新しいコンテンツを記憶部２２に記憶する。このとき、記憶部２２においては古いコンテンツは常に新しいコンテンツに更新される。詳しくは後述するが、コンテンツの種類は複数種類あって、本実施形態では、生成部２６はこれら複数種類のコンテンツを全て生成し記憶部２２に記憶する。 The generation unit 26 generates content to be provided to the television 3 from the processing unit 21 based on the usage information stored in the storage unit 22. The generation unit 26 generates new content every time the information acquisition unit 20 acquires usage information, and stores the new content in the storage unit 22. At this time, in the storage unit 22, old content is always updated to new content. Although details will be described later, there are a plurality of types of content, and in the present embodiment, the generation unit 26 generates all of the plurality of types of content and stores them in the storage unit 22.
　動作検知部２７は、テレビ３から送信されるサーチ信号に基づいて、テレビ３が「オン」・「オフ」のいずれの状態にあるかを検知する。テレビ３は、自己に関連するサービスを提供する機器のアドレスが予め登録されており、登録されたアドレス宛に探索用のコマンドからなるサーチ信号をマルチキャストで送信する。管理装置２は、テレビ用インタフェース２９にてサーチ信号を受信すると、サーチ信号の送信元のテレビ３に対して、サーチ信号への応答としてテレビ用インタフェース２９からサーチ応答を返信する。 The operation detection unit 27 detects whether the television 3 is in an “on” or “off” state based on a search signal transmitted from the television 3. The television 3 has registered in advance the address of a device that provides a service related to itself, and transmits a search signal including a search command to the registered address by multicast. When receiving the search signal at the television interface 29, the management device 2 returns a search response from the television interface 29 as a response to the search signal to the television 3 that is the transmission source of the search signal.
　ここで、テレビ３は、電源がオンした後、所定時間（たとえば３分）間隔でサーチ信号を発信する。管理装置２は、テレビ３の電源がオンした後で当該テレビ３から最初に送信されたサーチ信号を受けると、このテレビ３がオンしたことを動作検知部２７にて検知する。その後、管理装置２は、所定時間間隔で送信されてくるサーチ信号を受信することにより、テレビ３がオン状態を継続していることを動作検知部２７にて検知し、サーチ信号を受信できなくなると、テレビ３がオフしたことを動作検知部２７にて検知する。なお、テレビ３の電源がオンしてから最初にサーチ信号が送信されるまでに要する時間は数秒程度である。 Here, after the power is turned on, the television 3 transmits a search signal at predetermined time intervals (for example, 3 minutes). When the management device 2 receives a search signal first transmitted from the television 3 after the power of the television 3 is turned on, the operation detection unit 27 detects that the television 3 is turned on. Thereafter, the management device 2 receives the search signal transmitted at a predetermined time interval, so that the operation detection unit 27 detects that the television 3 continues to be on and cannot receive the search signal. Then, the operation detection unit 27 detects that the television 3 is turned off. Note that the time required for the search signal to be transmitted for the first time after the television 3 is turned on is about several seconds.
　また、条件取得部２８は、テレビ３がオンしたタイミングに関する条件情報として、テレビ３がオンした時刻を表す情報を取得する。本実施形態では、テレビ３から送信されるサーチ信号に現在時刻を表す時刻情報が含まれており、条件取得部２８は、テレビ３の電源がオンした後で当該テレビ３から最初に送信されるサーチ信号を受けて、テレビ３がオンした時刻を表す条件情報を取得する。 Further, the condition acquisition unit 28 acquires information indicating the time when the television 3 is turned on as the condition information regarding the timing when the television 3 is turned on. In the present embodiment, time information indicating the current time is included in the search signal transmitted from the television 3, and the condition acquisition unit 28 is first transmitted from the television 3 after the television 3 is turned on. In response to the search signal, condition information indicating the time when the television 3 is turned on is acquired.
　なお、管理装置２は、処理部２１にて蓄電池８の充放電の制御、並びに各負荷５のオンオフ制御についても可能となるように構成されていてもよいが、処理部２１によるこれらの制御についての詳細な説明は省略する。管理装置２の主な機能である処理部２１、情報取得部２０、生成部２６、動作検知部２７、条件取得部２８は、マイコン（マイクロコンピュータ）を主体として実現される。 In addition, although the management apparatus 2 may be comprised so that the control of charging / discharging of the storage battery 8 and the on / off control of each load 5 may be possible in the processing unit 21, these controls by the processing unit 21 The detailed description of is omitted. The processing unit 21, the information acquisition unit 20, the generation unit 26, the operation detection unit 27, and the condition acquisition unit 28, which are main functions of the management device 2, are realized mainly with a microcomputer.
　ところで、本実施形態の管理装置２においては、処理部２１は、テレビ３がオンしたことをトリガとして、生成部２６で生成されたコンテンツをテレビ３に表示させる。さらに、処理部２１は、条件取得部２８で取得された条件情報に応じて、コンテンツの種類を複数種類の中から選択し、選択した種類のコンテンツをテレビ３に表示させる。 By the way, in the management device 2 of the present embodiment, the processing unit 21 displays the content generated by the generation unit 26 on the television 3 with the television 3 being turned on as a trigger. Further, the processing unit 21 selects a content type from a plurality of types according to the condition information acquired by the condition acquisition unit 28 and causes the television 3 to display the selected type of content.
　すなわち、管理装置２の動作検知部２７は、テレビ３がオンしたことを検知するとトリガを発生し、このトリガを受けて、処理部２１が記憶部２２に記憶されているコンテンツをテレビ３に提供する。このとき、管理装置２はテレビ３がオンしたタイミングに関する条件情報（ここでは、テレビ３がオンした時刻を表す情報）を条件取得部２８にて取得し、当該条件情報に応じたコンテンツの種類を処理部２１にて選択する。 That is, the operation detection unit 27 of the management device 2 generates a trigger when detecting that the television 3 is turned on, and the processing unit 21 provides the content stored in the storage unit 22 to the television 3 in response to the trigger. To do. At this time, the management apparatus 2 acquires the condition information regarding the timing when the television 3 is turned on (in this case, information indicating the time when the television 3 is turned on) by the condition acquisition unit 28, and selects the type of content corresponding to the condition information. Selection is made by the processing unit 21.
　ここにおいて、管理装置２の記憶部２２には、複数種類のコンテンツについて、コンテンツの種類と条件情報とが対応付けられた条件テーブルが予め記憶されている。つまり、記憶部２２の記憶領域の一部は、コンテンツの種類と条件情報との対応関係を表す条件テーブルを記憶する条件記憶部として機能する。処理部２１は、動作検知部２７でトリガが発生すると、記憶部２２の条件テーブルを参照して、条件取得部２８から取得した条件情報に条件テーブル上で対応するコンテンツの種類を選択する。 Here, the storage unit 22 of the management device 2 stores in advance a condition table in which content types and condition information are associated with each other for a plurality of types of content. That is, a part of the storage area of the storage unit 22 functions as a condition storage unit that stores a condition table representing the correspondence between the type of content and the condition information. When a trigger is generated in the operation detection unit 27, the processing unit 21 refers to the condition table in the storage unit 22 and selects the type of content corresponding to the condition information acquired from the condition acquisition unit 28 on the condition table.

　なお、本実施形態では、上述の通り、処理部２１がコンテンツを提供するＷｅｂサーバとしての機能を有し、テレビ３が処理部２１から提供されるコンテンツを閲覧するＷｅｂブラウザとして機能を有している。従って、利用者が管理装置２に付属の図示しない操作部を操作してテレビ３に表示されるＷｅｂブラウザを閉じるか別のコンテンツを選択することにより、当該コンテンツの終了要求が受け付けられ、処理部２１は当該コンテンツのテレビ３への表示を終了することになる。 In the present embodiment, as described above, the processing unit 21 has a function as a Web server that provides content, and the TV 3 has a function as a Web browser that browses content provided from the processing unit 21. Yes. Therefore, when the user operates an operation unit (not shown) attached to the management apparatus 2 to close the Web browser displayed on the television 3 or select another content, the end request for the content is accepted, and the processing unit 21 ends the display of the content on the television 3.
　ただし、この限りでなく、例えばテレビ３がオンしたことを検知して処理部２１がコンテンツをテレビ３に提供すると同時に図示しないタイマーで計時し、所定の時間（例えば２～３分）が経過すると終了コマンドを処理部２１からテレビ３へ送信してコンテンツのテレビ３への表示を自動的に終了するように構成されてもよい。また、この所定の時間は、例えば利用者によって予め自由に設定変更が可能であってもよい。また、所定の時間が経過するとコンテンツを終了させるのではなく、上書コマンドを処理部２１からテレビ３へ送信して表示優先度が高い別のコンテンツを表示させるように構成されてもよい。 However, the present invention is not limited to this. For example, when the television set 3 is detected and the processing unit 21 provides the content to the television 3, the time is counted by a timer (not shown), and a predetermined time (for example, 2 to 3 minutes) elapses. An end command may be transmitted from the processing unit 21 to the television 3 so that the display of the content on the television 3 is automatically terminated. The predetermined time may be freely set and changed in advance by a user, for example. Further, instead of ending the content when a predetermined time has elapsed, an overwriting command may be transmitted from the processing unit 21 to the television 3 to display another content having a high display priority.
　なお、コンテンツの終了については、上述のように管理装置２側で行うだけでなく、テレビ３側で行われてもよい。例えば、一定時間経過するとテレビ３側で強制的にＷｅｂブラウザを終了するように構成されてもよいし、利用者が図示しないテレビリモコンの操作を通じてＷｅｂブラウザを終了するように構成されてもよい。 Note that the end of the content may be performed not only on the management device 2 side as described above but also on the television 3 side. For example, the web browser may be forcibly terminated on the television 3 side after a predetermined time has elapsed, or the user may be configured to terminate the web browser through an operation of a television remote controller (not shown).
　次に、エネルギー管理システム１の動作について、図３を参照して説明する。なお、図３では住宅内にテレビ３が複数台（ここでは３台）ある場合を例示しており、これら第１～第３のテレビ３，３，３は各々が管理装置２に接続され、管理装置２から提供されるコンテンツを閲覧するＷｅｂブラウザとしての機能を有している。 Next, the operation of the energy management system 1 will be described with reference to FIG. Note that FIG. 3 illustrates the case where there are a plurality of televisions 3 (here, three) in the house. Each of the first to third televisions 3, 3, and 3 is connected to the management apparatus 2, It has a function as a Web browser for browsing content provided from the management apparatus 2.
　まず、第１～第３の全てのテレビ３，３，３がオフの状態では、管理装置２は、情報取得部２０にて使用情報を定期的に取得し、生成部２６にてコンテンツを生成して記憶部２２に記憶する。 First, when all the first to third televisions 3, 3, 3 are off, the management apparatus 2 periodically acquires usage information by the information acquisition unit 20 and generates content by the generation unit 26. And stored in the storage unit 22.
　第１のテレビ３がオンすると、数秒後、第１のテレビ３は管理装置２に対してサーチ信号を送信する。このサーチ信号を受けた管理装置２は、第１のテレビ３がオンしたことを動作検知部２７にて検知し、第１のテレビ３に対してサーチ応答を返信する。このとき、管理装置２は、条件取得部２８にて、サーチ信号に含まれる時刻情報から第１のテレビ３がオンした時刻を取得する。 When the first television 3 is turned on, after a few seconds, the first television 3 transmits a search signal to the management device 2. Upon receiving this search signal, the management device 2 detects that the first television 3 is turned on by the operation detection unit 27 and returns a search response to the first television 3. At this time, the management apparatus 2 uses the condition acquisition unit 28 to acquire the time when the first television 3 is turned on from the time information included in the search signal.
　さらに、管理装置２は、第１のテレビ３がオンしたことをトリガとして、処理部２１にてテレビ３に表示させるコンテンツを選択する。このとき、処理部２１は、条件取得部２８で取得された条件情報に応じて、コンテンツの種類を複数種類の中から選択する。 Further, the management device 2 selects content to be displayed on the television 3 by the processing unit 21 with the first television 3 being turned on as a trigger. At this time, the processing unit 21 selects a content type from a plurality of types according to the condition information acquired by the condition acquisition unit 28.
　処理部２１にてコンテンツが選択されると、管理装置２は、第１のテレビ３に対して、提供可能なコンテンツがある旨を知らせるイベント通知を送信する。第１のテレビ３は、イベント通知を受けると、コンテンツ要求を管理装置２に送信し、コンテンツ要求への応答（コンテンツ応答）として管理装置２から提供されるコンテンツを画面に表示する。 When content is selected by the processing unit 21, the management device 2 transmits an event notification notifying that there is content that can be provided to the first television 3. Upon receiving the event notification, the first television 3 transmits a content request to the management apparatus 2 and displays the content provided from the management apparatus 2 on the screen as a response to the content request (content response).
　その後、第１のテレビ３は、オフされるまでは所定時間間隔で管理装置２にサーチ信号を送信する。管理装置２は、所定時間間隔で送信されてくるサーチ信号を受信できなくなると、第１のテレビ３がオフしたことを動作検知部２７にて検知する。 Thereafter, the first television 3 transmits a search signal to the management device 2 at predetermined time intervals until it is turned off. When the management apparatus 2 becomes unable to receive a search signal transmitted at a predetermined time interval, the operation detection unit 27 detects that the first television 3 has been turned off.
　以上説明した構成の管理装置２によれば、エネルギー（電力）の使用状況に基づいて生成されたコンテンツが、プッシュ方式でテレビ３に表示されるので、ユーザはテレビ３の画面を見てエネルギーの使用状況に関する情報を得ることができる。この種のコンテンツを表示する場合、即時性は重要ではないが、ユーザの視界に入りやすい位置に表示することが求められる。そのため、コンテンツを表示する媒体として、ユーザの視界に入りやすいテレビ３が適している。 According to the management device 2 having the configuration described above, the content generated based on the usage state of energy (electric power) is displayed on the television 3 by the push method. Information on usage status can be obtained. When displaying this type of content, immediacy is not important, but it is required to display it at a position that is easy to enter the user's field of view. Therefore, the television 3 that easily enters the user's field of view is suitable as a medium for displaying content.
　ここで、コンテンツはテレビ３がオンしたことをトリガとして表示されるので、テレビジョン放送の視聴中にコンテンツがテレビ３の画面に表示される場合に比べて、テレビジョン放送の視聴というテレビ３本来の機能の妨げとなりにくい。すなわち、電力の使用状況のように即時性の高くない情報に関してはあまり頻繁に表示されるとテレビジョン放送の視聴の妨げとなるのに対し、本実施形態では、テレビ３がオンしたときにのみ表示されるのでテレビジョン放送の視聴の妨げとはなりにくい。 Here, since the content is displayed as a trigger when the television 3 is turned on, the content of the television 3 that is the viewing of the television broadcast is compared with the case where the content is displayed on the screen of the television 3 during the viewing of the television broadcast. It is hard to interfere with the function of That is, information that is not immediate, such as power usage status, is displayed too frequently, which hinders viewing of television broadcasts. In the present embodiment, only when the television 3 is turned on. Since it is displayed, it is unlikely to obstruct viewing of the television broadcast.
　しかも、テレビ３に表示されるコンテンツの種類は、テレビ３がオンしたタイミングに関する条件情報に応じて最適化されることになる。本実施形態の場合、条件情報はテレビ３がオンした時刻を表す情報であるから、テレビ３がオンした時間帯に応じてテレビ３に表示されるコンテンツの種類が最適化されることになる。 Moreover, the type of content displayed on the television 3 is optimized according to the condition information regarding the timing when the television 3 is turned on. In the case of the present embodiment, the condition information is information indicating the time when the television 3 is turned on, so that the type of content displayed on the television 3 is optimized according to the time zone when the television 3 is turned on.
　また、コンテンツの種類と条件情報との対応関係は記憶部２２に記憶された条件テーブルによって決められているので、ユーザは、記憶部２２内の条件テーブルを変更するだけで、コンテンツの種類と条件情報との対応関係を容易に変更できるという利点がある。そのため、記憶部２２内の条件テーブルを変更する機能が管理装置２に付加されていれば、ユーザにより適した種類のコンテンツをテレビ３に表示させることが可能になる。 In addition, since the correspondence between the content type and the condition information is determined by the condition table stored in the storage unit 22, the user can change the content type and the condition only by changing the condition table in the storage unit 22. There is an advantage that the correspondence with information can be easily changed. Therefore, if a function for changing the condition table in the storage unit 22 is added to the management device 2, it is possible to display on the television 3 a type of content that is more suitable for the user.
　ところで、管理装置２は、テレビ３がオフしてからオンするまでの経過時間が所定時間未満であれば、処理部２１がコンテンツの表示をキャンセルする構成であってもよい。この構成では、テレビ３がオフしてからオンするまでの経過時間が所定時間未満であれば、動作検知部２７にてテレビ３がオンしたことが検知されトリガが発生しても、テレビ３にはコンテンツが表示されることはない。 Incidentally, the management device 2 may be configured such that the processing unit 21 cancels the display of content if the elapsed time from when the television 3 is turned off to when it is turned on is less than a predetermined time. In this configuration, if the elapsed time from when the television 3 is turned off to when the television 3 is turned on is less than a predetermined time, the operation detector 27 detects that the television 3 is turned on and a trigger is generated. Will not display content.
　これにより、テレビ３がオフされた後すぐにオンされる場合には、テレビ３にコンテンツは表示されない。すなわち、テレビ３が頻繁にオンオフされるような場合において、テレビ３がオンする度にコンテンツが表示されると、テレビジョン放送の視聴というテレビ３本来の機能の妨げとなる可能性があるが、上記構成によればこのような事態を回避できる。 Thus, if the television 3 is turned on immediately after it is turned off, the content is not displayed on the television 3. That is, in the case where the television 3 is frequently turned on and off, if the content is displayed each time the television 3 is turned on, there is a possibility that the original function of the television 3 of viewing the television broadcast may be hindered. According to the above configuration, such a situation can be avoided.
　なお、図３では複数台のテレビ３の各々が管理装置２に接続されＷｅｂブラウザとしての機能を有する場合を例示したが、この例に限らず、管理装置２に接続されるテレビ３は１台だけであってもよい。 3 illustrates the case where each of the plurality of televisions 3 is connected to the management device 2 and has a function as a Web browser. However, the present invention is not limited to this example, and one television 3 connected to the management device 2 is provided. It may be only.
　また、管理装置２の情報取得部２０は、電気機器や給湯設備などの運転状態を通信により取得し、この運転状態に基づいてエネルギーの使用状況に関する使用情報を取得する構成であってもよい。 Further, the information acquisition unit 20 of the management device 2 may be configured to acquire the operation state of the electrical equipment, the hot water supply facility, and the like by communication and acquire the usage information regarding the energy usage state based on the operation state.
