Calculation is performed using information stored in the recording unit 22 as necessary.
　制御部２０は、電力情報サーバ１２から電力に関する情報を受け取る。受け取る方法としては、電力情報サーバ１２からのプッシュまたは、電気機器制御装置１からの定期的な問い合わせによる方法があり、そのどちらか、もしくは両方の方法で電力に関する情報を受信する。電力に関する情報としては、所定の期間に電気料金を指定するものがある。期間については、一定間隔で連続した指定がなされる場合や、一定期間のみの指定がなされる場合などがある。指定される情報については、優先度が指定される場合がある。情報が更新されるタイミングは、定時で更新される場合、任意のタイミングで更新される場合がある。通常は少なくとも指定期間が終了する前までには更新される。 The control unit 20 receives information about power from the power information server 12. As a receiving method, there is a method by push from the power information server 12 or a periodic inquiry from the electric equipment control device 1, and information on power is received by either or both methods. As information about electric power, there is information that specifies an electricity bill for a predetermined period. As for the period, there are a case where designation is made continuously at regular intervals, and a case where designation is made only for a certain period. For information to be specified, a priority may be specified. When the information is updated at a fixed time, it may be updated at an arbitrary timing. Usually, it is updated at least before the end of the designated period.
　制御部２０は、電気機器を制御する計画を立てるために、宅内の電力の需給予測を行う。その手順は下記の通りである。まず、記録部２２で蓄積されている気象情報と電力量に関する情報を利用して予測を行う。例えば、気象情報に含まれる特定の項目と電力の実績情報との相関に基づく予測を行い、予測日の天気予報に最も適合した消費電力の予測結果情報を計算する。 The control unit 20 predicts the supply and demand of electric power in the house in order to make a plan for controlling the electrical equipment. The procedure is as follows. First, prediction is performed using weather information stored in the recording unit 22 and information on the amount of electric power. For example, prediction based on the correlation between a specific item included in weather information and actual power information is performed, and power consumption prediction result information most suitable for the weather forecast on the prediction date is calculated.
　予測結果情報としては、予測消費電力と予測発電電力がある。予測消費電力はエアコン５等の電気機器で消費されると予想される電力であり、予測発電電力は太陽光発電ユニット１０が発電すると予想される電力である。 The prediction result information includes predicted power consumption and predicted generated power. The predicted power consumption is power that is expected to be consumed by an electrical device such as the air conditioner 5, and the predicted power generation is power that is expected to be generated by the solar power generation unit 10.
　制御部２０は、予測結果情報に基づき、電気機器の制御情報を計算する。制御情報とは、機器を制御する内容と制御のタイミングがセットになった情報である。計算の方法については後述する。 The control unit 20 calculates control information of the electrical device based on the prediction result information. The control information is information in which the content for controlling the device and the control timing are set. The calculation method will be described later.
　なお、制御の方針はさまざまな方針が考えられるが、複数の方針を記録部２２に登録しておき、登録した複数の方針を表示部２３で表示させ、ユーザが選択できるようにしてもよい。 Although various control policies can be considered, a plurality of policies may be registered in the recording unit 22, and the registered plurality of policies may be displayed on the display unit 23 so that the user can select them.
　次に、予測結果情報と制御情報に基づき、電力状態情報を計算する。電力状態情報としては、蓄電池ユニット９の予測蓄電量と予測買い電力がある。予測蓄電量は予測開始時点の蓄電量実績を起点に制御情報に従って充放電が進んだと仮定することで、蓄電池ユニット９で蓄電されると予想される電力量である。また、予測買い電力は、予測消費電力と予測発電電力と蓄電池ユニット９の充放電電力の和から計算し、電力会社から買う必要があると予想される電力である。 Next, power state information is calculated based on the prediction result information and control information. As the power state information, there are a predicted power storage amount of the storage battery unit 9 and a predicted purchased power. The predicted storage amount is the amount of power that is expected to be stored in the storage battery unit 9 by assuming that charging / discharging has progressed according to the control information starting from the storage amount record at the start of prediction. The predicted purchased power is calculated from the sum of the predicted power consumption, the predicted generated power, and the charge / discharge power of the storage battery unit 9, and is expected to be purchased from an electric power company.
　以上のように、制御部２０は、予測結果情報、制御情報、電力状態情報を生成し、これらを記録部２２に記録する。さらに、制御部２０は、記録された各情報に基づき、画面情報を生成し、表示部２３や表示端末１１に生成した画面情報を表示させる。また、制御情報に従って、電気機器の制御を行う。 As described above, the control unit 20 generates prediction result information, control information, and power state information, and records them in the recording unit 22. Further, the control unit 20 generates screen information based on each recorded information, and displays the generated screen information on the display unit 23 or the display terminal 11. In addition, the electric device is controlled according to the control information.
　電気機器制御装置１が、宅内の電気機器を制御する方法について図３を用いて説明する。図３は電気機器制御のための計画を生成する手順を示したフローチャートである。 A method in which the electrical equipment control apparatus 1 controls electrical equipment in the house will be described with reference to FIG. FIG. 3 is a flowchart showing a procedure for generating a plan for controlling the electrical equipment.
　制御部２０は、記録部２２に蓄積している電気料金と蓄積データから最適抑制可能快適度を算出する（１０１）。最適抑制可能快適度の計算方法については後述する。ここで快適度とは対象の環境に滞在している人間が快適であるか否かを示す尺度である。 The control unit 20 calculates the optimum restrainable comfort level from the electricity charges and accumulated data stored in the recording unit 22 (101). A method for calculating the optimum restrainable comfort level will be described later. Here, the comfort level is a scale indicating whether or not a person staying in the target environment is comfortable.
　快適度は、対象の環境の情報より快適度算出部２５で算出する。一例として、温度、湿度、放射温度、風速、人間の着衣の程度、人間の活動の程度を用いて人間が感じる快適度を計算する。計算方法としては温熱環境評価指数ＰＭＶ（Predicted Mean Vote,予測温冷感申告）などがある。 The comfort level is calculated by the comfort level calculation unit 25 from the information on the target environment. As an example, the degree of comfort felt by humans is calculated using temperature, humidity, radiation temperature, wind speed, human clothing level, and human activity level. As a calculation method, there is a thermal environment evaluation index PMV (Predicted Mean Vote).
　制御部２０は、最適抑制可能快適度を用いて電気機器を制御する計画を生成する（１０２）。 The control unit 20 generates a plan for controlling the electrical device using the optimum restrainable comfort level (102).
　制御部２０は、生成した計画を記録部２２に記録する（１０３）。 The control unit 20 records the generated plan in the recording unit 22 (103).
　制御部２０は、計画を記録した後、計画を更新するべきタイミングかどうか判断する（１０４）。ここで更新するべきタイミングとはユーザが計画更新を必要とするような操作を電気機器制御装置１に対して行った場合、電力情報サーバ１２からの情報が更新された場合、現在時刻が所定の時刻に達した場合、センサ４から得た情報に変動があった場合、などがある。 After recording the plan, the control unit 20 determines whether it is time to update the plan (104). The timing to be updated here means that when the user performs an operation that requires a plan update on the electric device control apparatus 1, when the information from the power information server 12 is updated, the current time is predetermined. There are cases where the time has been reached, information obtained from the sensor 4 has changed, and so on.
　手順１０４の判断にて計画更新が必要と判断された場合、手順１０１の処理に戻る。 If it is determined that the plan needs to be updated in step 104, the process returns to step 101.
　手順１０４の判断にて計画更新が不要と判断された場合、制御部２０は、記録部２２に記録した計画を参照して、制御実施が必要かどうか判断する（１０５）。 When it is determined that the plan update is unnecessary in the determination of the procedure 104, the control unit 20 refers to the plan recorded in the recording unit 22 and determines whether the control needs to be performed (105).
　手順１０５の判断にて制御実施が必要と判断された場合、制御部２０は、記録部２２に記録した計画を参照して、実施するべき制御を実施する。例えば、制御部２０は通信部２４と通信路３を介して、エアコン５の設定温度を更新する、照明のＯＮ／ＯＦＦを行う、テレビのＯＮ／ＯＦＦを行う、および蓄電池ユニット９に充放電を指示する、などの制御を行う。制御を実施した後は、手順１０４の判断に戻る。 When it is determined in the step 105 that the control needs to be performed, the control unit 20 refers to the plan recorded in the recording unit 22 and performs the control to be performed. For example, the control unit 20 updates the set temperature of the air conditioner 5 through the communication unit 24 and the communication path 3, turns on / off lighting, turns on / off the TV, and charges / discharges the storage battery unit 9. Control such as instructing. After the control is performed, the process returns to the determination in step 104.
　手順１０５の判断にて制御実施が不要と判断された場合、手順１０４の判断に戻る。 If it is determined in step 105 that control is not required, the process returns to step 104.
　制御部２０は、記録部２２に蓄積したデータを分析することで最適抑制可能快適度を計算する。使用するデータについて図４、図５を用いて説明する。 The control unit 20 calculates the optimum restrainable comfort level by analyzing the data accumulated in the recording unit 22. The data to be used will be described with reference to FIGS.
　図４は本実施例で使用するデータテーブルの一例である。このテーブルは電子情報として記録部２２に保持されている。抑制可能快適度１１０と電気料金差分１２０、対象期間１２１のデータが１セットとして格納されている。制御部２０は図４のテーブルのデータを用いて最適抑制可能快適度を算出する。 FIG. 4 is an example of a data table used in this embodiment. This table is held in the recording unit 22 as electronic information. Data of the controllable comfort level 110, the electricity rate difference 120, and the target period 121 are stored as one set. The control unit 20 calculates the optimum restrainable comfort level using the data in the table of FIG.
　図５は使用するデータの意味を表す図である。グラフ１３０は横軸の時間帯と縦軸の電気料金の関係を示している。グラフ１３１は横軸の時間帯と縦軸のエアコン５の設定温度の関係を示している。グラフ１３２は横軸の時間帯と縦軸のエアコン５が設置されている部屋の快適度の関係を示している。快適度が高いほど、快適である。 Fig. 5 shows the meaning of the data used. The graph 130 shows the relationship between the time zone on the horizontal axis and the electricity rate on the vertical axis. A graph 131 shows the relationship between the time zone on the horizontal axis and the set temperature of the air conditioner 5 on the vertical axis. The graph 132 shows the relationship between the time zone on the horizontal axis and the comfort level of the room where the air conditioner 5 is installed on the vertical axis. The higher the comfort level, the more comfortable.
　図５では、対象期間１２１で示している期間に、電力情報サーバ１２から電力料金が上昇すると指定された場合を前提としている。上昇した電力料金分、すなわち電気料金差分１２０は、臨時の電力料金１３４から通常の電力料金１３５を引くことで計算できる。あらかじめ契約してある基本的な電力料金がある場合は、通常の電力料金１３５は、契約した内容に従った電力料金とする。毎日電力料金が更新される場合は、定期的に更新される電気料金を通常の電気料金１３５として扱う。 In FIG. 5, it is assumed that the power information server 12 specifies that the power charge will increase during the period indicated by the target period 121. The increased power charge, that is, the electricity charge difference 120 can be calculated by subtracting the normal power charge 135 from the temporary power charge 134. When there is a basic power charge contracted in advance, the normal power charge 135 is a power charge according to the contracted contents. When the electricity rate is updated every day, the electricity rate that is regularly updated is treated as a normal electricity rate 135.
　グラフ１３１は、対象期間１２１において、ユーザが設定温度を変更した場合を示している。変更の結果、変更された設定温度１３６になる。あらかじめ設定された設定温度１３７は、制御部が手順１０６の処理において設定したものである。 The graph 131 shows a case where the user changes the set temperature in the target period 121. As a result of the change, the set temperature 136 is changed. The preset temperature 137 set in advance is set by the control unit in the process of step 106.
　グラフ１３２は、対象期間１２１において、ユーザが設定温度を変更した結果、快適度が変化した場合を表している。対象期間１２１に入る前の快適度から対象期間１２１中の最低の快適度を引いたものが、抑制可能快適度１１０である。 The graph 132 represents a case where the comfort level changes as a result of the user changing the set temperature in the target period 121. The controllable comfort level 110 is obtained by subtracting the minimum comfort level during the target period 121 from the comfort level before entering the target period 121.
　最適抑制可能快適度を計算する方法を説明する。計算方法の一例として回帰分析を用いる方法がある。抑制可能快適度１１０を目的変数、電気料金差分１２０を説明変数とした一次方程式で表される関係にあると仮定して、図４のテーブルのデータをサンプルとして、一次方程式のパラメータを最小自乗法などの方法で算出する。算出したパラメータを一次方程式に適用することで、ある電気料金差分１２０が与えられた場合に、抑制可能快適度１１０を決定することができる。 説明 Explain how to calculate the optimal comfort level. As an example of the calculation method, there is a method using regression analysis. Assuming that the controllable comfort level 110 is an objective variable, and the electricity rate difference 120 is an explanatory variable, the relationship is expressed by a linear equation. The data in the table of FIG. Calculate by such a method. By applying the calculated parameter to the linear equation, the restrainable comfort level 110 can be determined when a certain electricity rate difference 120 is given.
　サンプルとするデータは対象期間ごとに集計する。例えば図４のテーブルの場合、対象期間１２１が一致しているＮｏ１とＮｏ３が集計対象となる。対象期間１２１は完全に一致している必要はなく、例えば午前または午後のどちらに振り分けて集計してもよい。このようにすることで、時間帯ごとのユーザの振る舞いを区別することができる。 ∙ Collect data for each sample period. For example, in the case of the table in FIG. 4, No1 and No3 that have the same target period 121 are counted. The target periods 121 do not need to be completely coincident, and may be aggregated, for example, in the morning or in the afternoon. By doing in this way, a user's behavior for every time zone can be distinguished.
　一次方程式では一対のパラメータの関係性しか表すことができないが、例えば図６に示すような複数のパラメータであっても、重回帰分析の手法で関係性を計算可能である。 In the linear equation, only the relationship between a pair of parameters can be expressed, but even for a plurality of parameters as shown in FIG. 6, for example, the relationship can be calculated by the method of multiple regression analysis.
　ここで抑制可能快適度（温熱環境）１１１は、抑制可能快適度１１０と同等のパラメータである。 Here, the controllable comfort level (thermal environment) 111 is a parameter equivalent to the controllable comfort level 110.
　抑制可能快適度（テレビ）１１２は、テレビ視聴中は快適であるという前提に基づくパラメータである。値が１であれば電源がＯＮ、０であればＯＦＦであることを示す。 The controllable comfort level (TV) 112 is a parameter based on the premise that the user is comfortable while watching TV. A value of 1 indicates that the power supply is ON, and a value of 0 indicates OFF.
　外気温１４１は、センサ４から取得した室外の気温を表す。室外にセンサ４を設置しない場合は、気象情報サーバ１３から取得した天気情報から設定してもよい。 The outdoor temperature 141 represents the outdoor temperature acquired from the sensor 4. When the sensor 4 is not installed outside, the weather information acquired from the weather information server 13 may be set.
　湿度１４２は、センサ４から取得した室内の湿度を表す。 Humidity 142 represents the indoor humidity acquired from the sensor 4.
　例えば抑制可能快適度（温熱環境）１１１と、抑制可能快適度（テレビ）１１２を目的変数とし、外気温１４１、湿度１４２および電気料金差分１２０を説明変数として、蓄積したデータで重回帰分析を行うことで、説明変数から目的変数の値を示すことができる。 For example, the multiple regression analysis is performed on the accumulated data using the controllable comfort level (thermal environment) 111 and the controllable comfort level (television) 112 as objective variables, and the outside air temperature 141, humidity 142, and electricity rate difference 120 as explanatory variables. Thus, the value of the objective variable can be shown from the explanatory variable.
　最適抑制可能快適度の初期設定値については、０とすることで、快適性抑制を一切しないことを表すことができる。また、図７に示すような画面でユーザにその程度を指定してもらうことで、初期値を決定しても良い。図７の画面２００は、快適性と電気料金のどちらを優先するかの程度を示しており、画面を触れて操作をする。例えば最適抑制可能快適度が０の場合は、バー２０１が左端まで寄っている状態で表される。また最適抑制可能快適度が十分大きい場合は、バー２０１が右端までよっている状態で表される。バーの位置が左に寄るほど、最適抑制可能価値的度が０に近づくような関係である。 ∙ By setting the initial value of the comfort level that can be optimally suppressed to 0, it is possible to indicate that comfort is not suppressed at all. Further, the initial value may be determined by having the user specify the degree on the screen as shown in FIG. A screen 200 in FIG. 7 shows the degree of priority given to comfort or electricity charge, and is operated by touching the screen. For example, when the degree of comfort that can be optimally suppressed is 0, the bar 201 is expressed in a state where it is close to the left end. In addition, when the optimum restrainable comfort level is sufficiently large, the bar 201 is expressed in a state where it extends to the right end. The relationship is such that the closer the bar position is to the left, the closer the optimal suppression possible value level becomes to zero.
　制御部２０は、図３の手順１０２において、各電気機器を制御するために、方針に従う所定の期間分の計画を生成する。 The control unit 20 generates a plan for a predetermined period according to the policy in order to control each electric device in the procedure 102 of FIG.
　制御内容は各電気機器に応じて異なる。例えばエアコン５の場合は、制御可能なパラメータに設定温度がある。例えば、所定の電気料金ができるだけ安くなるようにしつつ、所定の快適度を達成できるような方針に基づいてエアコン５の時系列にそった設定温度の計画を立てる。 The control content varies depending on each electric device. For example, in the case of the air conditioner 5, there is a set temperature as a controllable parameter. For example, a plan for the set temperature in accordance with the time series of the air conditioner 5 is made based on a policy that can achieve a predetermined comfort level while making a predetermined electricity price as low as possible.
　計算のため時系列は離散的な時間として扱う。例えば１０分単位で設定温度を制御可能とし、所定の時刻に達したら設定温度を変えるような動作をすることで、所望の快適度、消費電力を実現していく。 For the calculation, the time series is treated as discrete time. For example, the set temperature can be controlled in units of 10 minutes, and a desired comfort level and power consumption are realized by performing an operation of changing the set temperature when a predetermined time is reached.
　時系列の設定温度の組み合わせには多くの場合があるため、適切な設定温度の組み合わせを発見する必要がある。解法として、設定温度と所定の快適度と電気料金の制約条件を線形の式にて表現することで、線形計画法などの数理的手法を用いて解く方法や、最適性は保証せずに事前に決定したポリシーに応じて設定温度を決定する方法などがある。 Since there are many cases of time-series set temperature combinations, it is necessary to find an appropriate set temperature combination. As a solution method, by expressing the set temperature, the predetermined comfort level, and the constraint condition of the electricity rate with a linear expression, it can be solved using a mathematical method such as linear programming, or the optimality is not guaranteed in advance. There is a method of determining the set temperature according to the policy determined in (1).
　複数の計画候補から最適な計画を選び出す方法について、図８のフローチャートを用いて説明する。 A method for selecting an optimum plan from a plurality of plan candidates will be described with reference to the flowchart of FIG.
　はじめに制御部２０は、目標快適度を計算する（１５１）。目標快適度とは、ある対象期間に達成するべき快適度である。目標快適度は、対象期間に対応する理想的な快適度から最適抑制可能快適度を引いた快適度とする。 First, the control unit 20 calculates a target comfort level (151). The target comfort level is a comfort level to be achieved in a certain target period. The target comfort level is a comfort level obtained by subtracting the optimally restrainable comfort level from the ideal comfort level corresponding to the target period.
　次に制御部２０は、目標快適度を達成することを目標とした設定温度の制御計画の候補を計算する（１５２）。 Next, the control unit 20 calculates a control plan candidate for the set temperature aimed at achieving the target comfort level (152).
　制御部２０は、計画の設定温度を元に、制御部２０は快適度算出部２５を用いて快適度を計算する（１５３）。ある対象期間の快適度は、制御部２０が、事前に予測した、湿度、放射温度、風速の情報とあらかじめ仮定した情報の組み合わせから計算する。 The control unit 20 calculates the comfort level using the comfort level calculation unit 25 based on the set temperature of the plan (153). The comfort level in a certain target period is calculated from a combination of information on humidity, radiation temperature, and wind speed predicted in advance by the control unit 20 and information assumed in advance.
　計画の設定温度を元に、エアコンの消費電力を計算する（１５４）。気象情報サーバ１３から得た天気予報の情報とエアコンが設置されている部屋の気密性や日当たりの情報を総合して熱負荷を仮定することで、消費電力を計算できる。 Calculating the power consumption of the air conditioner based on the set temperature of the plan (154). The power consumption can be calculated by assuming the heat load by integrating the weather forecast information obtained from the weather information server 13 and the airtightness of the room where the air conditioner is installed and the daily information.
　そして制御部２０は、電力料金が安くかつ目標快適度を達成できているかどうか判断する（１５５）。 Then, the control unit 20 determines whether the power rate is low and the target comfort level is achieved (155).
　手順１５５の判断の結果、達成できていると判断した場合は、制御部２０は、制御計画候補を解として、記録部２２に格納する。 As a result of the determination in step 155, when it is determined that it has been achieved, the control unit 20 stores the control plan candidate as a solution in the recording unit 22.
　手順１５５の判断の結果、達成できていないと判断した場合は、制御部２０は、これ以上計算を継続するかどうか判定する（１５７）。 As a result of the determination in step 155, if it is determined that it has not been achieved, the control unit 20 determines whether or not to continue the calculation (157).
　手順１５７の判断の結果、計算を継続する場合は、手順１５２へ戻る。継続するかどうかの判断には、制御計画候補を生成した回数が所定の閾値を超えたかどうかを判断する方法や、目標快適度の達成の度合いを尺度として、収束するかどうかを判断する方法などがある。 If the result of determination in step 157 is to continue calculation, the process returns to step 152. In determining whether to continue, a method of determining whether the number of generations of control plan candidates has exceeded a predetermined threshold, a method of determining whether to converge using the degree of achievement of the target comfort level as a scale, etc. There is.
　手順１５７の判断の結果、計算を継続しない場合は、制御部２０は、計算した範囲で最良の制御計画候補を採用し（１５８）、手順１５６に従って計画を記録部２２へ格納する。もしくは、あらかじめ定めてある電力料金を優先するか快適度を優先するかの優先度方針に従って、組み合わせを選択してもよい。 If the calculation is not continued as a result of the determination in step 157, the control unit 20 adopts the best control plan candidate within the calculated range (158), and stores the plan in the recording unit 22 in accordance with step 156. Alternatively, the combination may be selected in accordance with a priority policy that gives priority to a predetermined power rate or to give priority to comfort.
　以上の手順でエアコンの設定温度と消費電力を繰り返し計算し、電力料金が安くかつ所定の快適度を達成できるような設定温度の組み合わせを決定する。 The above procedure repeatedly calculates the set temperature and power consumption of the air conditioner, and determines the combination of set temperatures that can achieve a specified comfort level at a low price.
　図４や図６に示すデータを、集める方法を説明する。最適抑制可能快適度は、電力料金が変化したことによる行動を反映したものでなければならないため、データの選択が重要である。不適切なデータを対象としてしまうと、ユーザの意図が正しく反映されないため、ユーザの意図を反映した適切なデータを選択する必要がある。適切なデータを用いることで、電気料金とユーザの行動の関連性を正しく学習することができる。 A method for collecting the data shown in FIGS. 4 and 6 will be described. The optimal controllable comfort level must reflect the behavior due to changes in the electricity rate, so data selection is important. If inappropriate data is targeted, the user's intention is not correctly reflected, so it is necessary to select appropriate data that reflects the user's intention. By using appropriate data, it is possible to correctly learn the relationship between electricity charges and user behavior.
　適切なデータを選択するための手順のシーケンスを図９に示す。 Figure 9 shows the sequence of procedures for selecting appropriate data.
　図９では、エアコン５の制御に着目している。 FIG. 9 focuses on the control of the air conditioner 5.
　電力情報サーバ１２が設定した電力情報が、通信路３を介して電気機器制御装置１に送信される（１６１）。 The power information set by the power information server 12 is transmitted to the electric equipment control apparatus 1 via the communication path 3 (161).
　電気機器制御装置１は、電力情報を受け取ったのちに、エアコン５の設定温度を確認する（１６２）。確認した設定温度は、後の処理でユーザの操作による温度変更があったかどうかを確認するために記録部２２へ格納しておく。 After receiving the power information, the electric equipment control device 1 confirms the set temperature of the air conditioner 5 (162). The confirmed set temperature is stored in the recording unit 22 in order to confirm whether or not the temperature has been changed by a user operation in a later process.
　電気機器制御装置１は、表示部２３にデマンドレスポンス情報を提示する（１６３）。 The electrical equipment control device 1 presents demand response information on the display unit 23 (163).
　そしてデマンドレスポンス情報の表示が完了した、もしくはユーザが確認ボタンなどを押されたら、表示を終了する（１６４）。デマンドレスポンス情報の種別によっては、一定期間表示したのちに、ユーザの確認を待たずに自動的に表示を終了してもよい。 When the display of demand response information is completed or the user presses a confirmation button, the display is terminated (164). Depending on the type of demand response information, after displaying for a certain period, the display may be automatically terminated without waiting for user confirmation.
　電気機器制御装置１は、ユーザが確認したことを電力情報サーバ１へ通知する（１６５）。デマンドレスポンス情報の種別によっては通知を省略してもよい。 The electric equipment control apparatus 1 notifies the power information server 1 that the user has confirmed (165). Notification may be omitted depending on the type of demand response information.
　ユーザの確認の後、電気機器制御装置１は、制御計画を生成する（１６６）。処理の内容は手順１０１、１０２、１０３と同等である。 After the user confirmation, the electric equipment control device 1 generates a control plan (166). The contents of the processing are the same as the procedures 101, 102, and 103.
　電気機器制御装置１は、制御部２０が生成した計画に基づいて、エアコン５に対して温度設定を行う（１６７）。 The electric equipment control device 1 performs temperature setting for the air conditioner 5 based on the plan generated by the control unit 20 (167).
　手順１６７以降、電気機器制御装置１は、手順１６８の範囲で示すように定期的に電気機器の監視を行う。この監視は電気料金が上昇している期間が終わるまで継続する。 After step 167, the electric device control apparatus 1 periodically monitors the electric device as shown in the range of the step 168. This monitoring will continue until the end of the period when electricity charges are rising.
　電気機器制御装置１は、定期的にエアコン５の設定温度の確認を定期的に行う（１６９）。 The electric equipment control apparatus 1 periodically checks the set temperature of the air conditioner 5 (169).
　電気機器制御装置１は、定期的にセンサ４の情報の確認を定期的に行う（１７１）。 The electrical equipment control device 1 periodically checks the information of the sensor 4 (171).
　ユーザがエアコン５の設定温度を変える（１７０）と、電気機器制御装置１は、定期的に設定温度を確認していることによって、変更されたことを知ることができる。ここで、エアコン５の設定温度変更のためには、リモートコントローラ等の操作装置を使っても良いし、ユーザの指示によって電気機器制御装置１が間接的にエアコン５の設定温度変更を行ってもよい。 When the user changes the set temperature of the air conditioner 5 (170), the electric equipment control device 1 can know that the change has been made by checking the set temperature periodically. Here, in order to change the set temperature of the air conditioner 5, an operating device such as a remote controller may be used, or even if the electric device control device 1 indirectly changes the set temperature of the air conditioner 5 according to a user instruction. Good.
　電気機器制御装置１は、電気料金が上昇する期間が終わったのちに、データ解析の判断を行う（１７２）。 The electric equipment control device 1 makes a data analysis decision after the period when the electricity rate increases (172).
　以上のような手順を踏むことで、電力情報サーバ１２からの情報をユーザに展開し、データの解析に必要な情報を収集することができる。 By following the above procedure, the information from the power information server 12 can be expanded to the user and information necessary for data analysis can be collected.
　手順１６３において、電気機器制御装置１がユーザに提供する画面は、ユーザへ電力に関わる情報を提供するためのものであり、分かりやすい情報を提供することで、ユーザに電力情報に応じた適切な行動を促すことができる。図を用いてその例を示す。 In step 163, the screen provided to the user by the electric appliance control device 1 is for providing information related to power to the user. By providing easy-to-understand information, the user can select an appropriate screen according to the power information. Can encourage action. An example is shown using the figure.
　図１０は、デマンドレスポンスをユーザに通知する画面２１０である。画面上には１４時から１６時の間の電気料金が、通常の料金の３倍になることを示している。 FIG. 10 shows a screen 210 for notifying the user of a demand response. The screen shows that the electricity charge between 14:00 and 16:00 is three times the normal charge.
　ユーザはこの画面を目視することで、電気料金が変わることを確認する。確認した場合には、ユーザは確認ボタン２１１を押す。確認ボタン２１１を押すと、制御部２０が画面を消す処理を行う。 The user confirms that the electricity price changes by viewing this screen. If confirmed, the user presses the confirmation button 211. When the confirmation button 211 is pressed, the control unit 20 performs a process of deleting the screen.
　図１１は、画面２１０が提供している情報に加えて、「一日の電気料金が、通常と比較して１００円増える見通しです。」という文面で一日の積算として計算した電気料金の上昇の度合いを示し、ユーザに電気料金上昇の影響を分かりやすく伝えている画面２２０である。 In addition to the information provided on the screen 210, FIG. 11 shows an increase in the electricity charge calculated as the total of the day in the text “The electricity charge per day is expected to increase by 100 yen compared to normal”. This is a screen 220 that shows the degree of power and conveys to the user the effect of an increase in the electricity bill in an easy-to-understand manner.
　上昇を考慮した電気料金は、制御部２０が、制御計画は変更せずに、電気料金のみを変更したと仮定して、一日の電力需給予測から計算する。 The electricity bill considering the rise is calculated from the daily power supply and demand forecast, assuming that the control unit 20 has changed only the electricity bill without changing the control plan.
　制御部２０が行うデータ解析の判断（１７２）について、図１２を用いて説明する。 Determination of data analysis (172) performed by the control unit 20 will be described with reference to FIG.
　制御部２０は、電気料金が上昇している対象期間１２１が終了しているかどうか判断する（３０１）。終了するまで待機する。 The control unit 20 determines whether or not the target period 121 in which the electricity rate is rising has ended (301). Wait for it to finish.
　手順３０１で、電気料金が上昇している対象期間１２１が終了したと判断できた場合、制御部２０は、ユーザの操作が、対象期間１２１の時間帯にあったかどうかを判断する（３０２）。エアコン５の場合のユーザの操作とは、設定温度の変更を指す。操作があったかどうかを区別する方法としては、電気料金が上昇している対象期間１２１対象期間１２１の開始時刻の一定時間前から対象期間１２１の終了時刻までの間に、設定温度の変更があった場合に、操作有りと判断すればよい。 When it is determined in the procedure 301 that the target period 121 in which the electricity rate is rising has ended, the control unit 20 determines whether the user's operation was in the time zone of the target period 121 (302). The user's operation in the case of the air conditioner 5 indicates a change in the set temperature. As a method for distinguishing whether or not there has been an operation, there has been a change in the set temperature from a certain time before the start time of the target period 121 to the end time of the target period 121 during the target period 121 where the electricity rate is rising In this case, it may be determined that there is an operation.
　制御部２０が、手順３０２で、操作有りと判断した場合、制御部２０は、記録部２２に格納してある計画のデータから、ユーザの操作によって変更される前の設定温度が、自動的に設定したものかどうか判断する（３０３）。 When the control unit 20 determines in step 302 that there is an operation, the control unit 20 automatically determines that the set temperature before the change by the user operation is made based on the plan data stored in the recording unit 22. It is determined whether it has been set (303).
　設定温度が自動的に設定されたものでない場合、制御部２０は、センサ４の情報を用いて、快適度算出部２５により快適度を算出する。算出する期間は対象期間１２１の間である。そしてユーザの操作がなかった場合に想定していた快適度とセンサ４で実測して計算した快適度の差を用いて実測した快適度が想定していた快適度より低下したかどうか判断する（３０４）。 When the set temperature is not automatically set, the control unit 20 calculates the comfort level by the comfort level calculation unit 25 using the information of the sensor 4. The period to calculate is during the target period 121. Then, it is determined whether or not the actually measured comfort level is lower than the assumed comfort level using the difference between the comfort level assumed when there is no user operation and the comfort level actually measured and calculated by the sensor 4 ( 304).
　快適度が低下したと判断できる場合は、制御部２０は、図４に示すデータテーブルに情報を登録する（３０５）。 If it can be determined that the comfort level has decreased, the control unit 20 registers information in the data table shown in FIG. 4 (305).
　手順３０４において、快適度が低下したと判断できない場合は、処理は終了する。手順３０４の判断によって、自動設定されていない設定温度に対して、快適度を下げたような温度設定をした場合のみ、その操作が学習対象となる。このようにすることで、電気料金が上がったことに対応して快適度を我慢したという行動を計画に反映できる。 If it cannot be determined in step 304 that the comfort level has decreased, the process ends. The operation is a learning target only when the temperature setting is set such that the comfort level is lowered with respect to the set temperature that is not automatically set based on the determination in step 304. In this way, it is possible to reflect in the plan the behavior of having put up with comfort in response to an increase in the electricity bill.
　手順３０３において、設定温度が自動的に設定されたものである場合、制御部２０は、センサ４の情報を用いて、快適度算出部２５により快適度を算出する。算出する期間は対象期間１２１の間である。そしてユーザの操作がなかった場合に想定していた快適度とセンサ４で実測して計算した快適度の差を用いて、実測した快適度が想定していた快適度に対して変化したかどうか判断する（３０６）。 In step 303, when the set temperature is automatically set, the control unit 20 calculates the comfort level by the comfort level calculation unit 25 using the information of the sensor 4. The period to calculate is during the target period 121. Whether or not the actually measured comfort level has changed with respect to the assumed comfort level, using the difference between the comfort level assumed when there was no user operation and the comfort level actually measured by the sensor 4 Judgment is made (306).
　そして快適度が変化したと判断できる場合は、制御部２０は、図４に示すデータテーブルに、抑制可能快適度１１０、電気料金差分１２０、対象期間１２１を登録する（３０５）。 If it can be determined that the comfort level has changed, the control unit 20 registers the controllable comfort level 110, the electricity rate difference 120, and the target period 121 in the data table shown in FIG. 4 (305).
　登録した際に、表示部２３に、図１３で示すような画面２３０を表示させてもよい。画面２３０では、データテーブルに情報を登録する前に、計算した最適抑制可能快適度に対応する快適性バランス２３１と、データテーブルに情報を登録した後に、計算した最適抑制可能快適度に対応する快適性バランス２３２を示している。ユーザはこの画面をみることで、自身の操作がどの程度、快適性バランスに影響したかを見てとることができる。 When registered, a screen 230 as shown in FIG. 13 may be displayed on the display unit 23. On the screen 230, the comfort balance 231 corresponding to the calculated optimum restrainable comfort before registering information in the data table and the comfort corresponding to the calculated optimum restrainable comfort after registering information in the data table. The sex balance 232 is shown. By viewing this screen, the user can see how much the user's operation has affected the comfort balance.
　手順３０６で、変化したと判断できない場合は、処理は終了する。手順３０６の判断によって、自動設定された設定温度に対して、快適度が変化するような温度設定をした場合のみ、その操作が学習対象となる。このようにすることで、計画に基づく快適度に対してユーザの希望がずれていたということを検知して、計画に反映できる。 If the procedure 306 cannot determine that it has changed, the process ends. Only when the temperature is set such that the comfort level changes with respect to the automatically set temperature based on the determination in step 306, the operation becomes a learning target. By doing in this way, it can detect that a user's hope has shifted | deviated with respect to the comfort based on a plan, and can reflect it in a plan.
　以上の構成および手順を実施することで、電気機器制御装置１は、ユーザの手を煩わせることなく自動的に電気料金とユーザの行動の関係性を学習することが可能である。学習の結果、ユーザが直接操作することなく、電気料金が変化したときに、電気機器制御装置１が適切な制御が行うことできるようになる。また電気料金の変化とは関係なくユーザが行った操作を学習対象としないことで、適切なデータを学習して、ユーザの意図を反映しない温度設定に基づく計画を立てないようにできる。また学習が進んだ後も、自動設定された温度設定かどうかを区別していることによって、学習の結果を随時最適に更新していくことができる。 By implementing the above configuration and procedure, the electric device control apparatus 1 can automatically learn the relationship between the electricity charge and the user's action without bothering the user. As a result of the learning, the electric appliance control device 1 can perform appropriate control when the electricity rate changes without direct operation by the user. Further, by not considering the operation performed by the user regardless of the change in the electricity bill, it is possible to learn appropriate data and avoid making a plan based on the temperature setting that does not reflect the user's intention. Further, even after learning progresses, by distinguishing whether or not the temperature setting is automatically set, the learning result can be updated optimally at any time.

　まず電力情報サーバ１２が設定した電力情報が、通信路３を介して電気機器制御装置１に送信される。（４０１）
　電気機器制御装置１は、電力情報を受け取ったのちに、エアコン５の設定温度を確認する（４０２）。確認した設定温度は、後の処理でユーザの操作による温度変更があったかどうかを確認するために記録部２２へ格納しておく。 First, the power information set by the power information server 12 is transmitted to the electrical device control apparatus 1 via the communication path 3. (401)
After receiving the power information, the electric equipment control device 1 checks the set temperature of the air conditioner 5 (402).

　そしてデマンドレスポンス情報を表示し、ユーザによって確認されたら、表示を終了する（４０５）。 Then, the demand response information is displayed, and when confirmed by the user, the display is terminated (405).
　電気機器制御装置１は、ユーザが確認したことを電力情報サーバ１２へ通知する（４０６）。デマンドレスポンス情報の種別によっては通知を省略してもよい。 The electrical equipment control device 1 notifies the power information server 12 that the user has confirmed (406). Notification may be omitted depending on the type of demand response information.
　電気機器制御装置１は、制御部２０が生成した計画に基づいて、エアコン５に対して温度設定を行う（４０７）。 The electric equipment control device 1 performs temperature setting for the air conditioner 5 based on the plan generated by the control unit 20 (407).
　手順４０７以降、電気機器制御装置１は、手順４０８の範囲で示すように定期的に電気機器の監視を行う。この監視は電気料金が上昇している期間が終わるまで継続する。 After step 407, the electric device control apparatus 1 periodically monitors the electric device as shown in the range of step 408. This monitoring will continue until the end of the period when electricity charges are rising.

　電気機器制御装置１は、定期的にセンサ４の情報を定期的に確認する（４１０）。 The electrical equipment control apparatus 1 periodically checks the information of the sensor 4 (410).
　手順４１０では、センサ４の赤外線センサの情報を取得している。この情報はエアコン５が設置されている部屋に人が在室しているかどうかを判断できるような精度をもった情報である。確認した情報は、確認した時刻と共に記録部２２へ格納する。 In step 410, information on the infrared sensor of the sensor 4 is acquired. This information is information having such an accuracy that it can be determined whether or not a person is present in the room where the air conditioner 5 is installed. The confirmed information is stored in the recording unit 22 together with the confirmed time.
　電気料金が上昇する期間が終わったのちに、データ解析の判断を行う（４１１）。 After the period when the electricity rate increases, the data analysis is judged (411).
　以上のような手順を踏むことで、電力情報サーバ１２からの情報をユーザに展開し、ユーザの在室を踏まえたデータの解析に必要な情報を収集することができる。 By following the procedure as described above, information from the power information server 12 can be expanded to the user, and information necessary for data analysis based on the user's occupancy can be collected.
　手順４０３において、表示する画面の例を図１５、図１６、図１７に示す。 Examples of screens to be displayed in the procedure 403 are shown in FIG. 15, FIG. 16, and FIG.
　図１５は、電力需給の状態を表す情報を備えた画面２４０を示している。画面２４０は、デマンドレスポンス情報の他に、通常の電力需給を示す画面２４１と、電気料金が３倍の場合を示す画面２４２と、確認ボタン２４３を持っている。 FIG. 15 shows a screen 240 having information indicating the state of power supply and demand. In addition to the demand response information, the screen 240 has a screen 241 indicating normal power supply and demand, a screen 242 indicating a case where the electricity rate is triple, and a confirmation button 243.
　画面２４１の詳細を図１６に示す。画面２４１は、通常の電気料金の上昇を考慮しない場合の宅内の消費電力グラフ２５０と、エアコン５の制御計画グラフ２５５から成っている。宅内の消費電力の積算値から一日の消費電力量予測２５１を表示している。また電力料金が上昇する対象期間を矢印２５２で図示している。 Details of the screen 241 are shown in FIG. The screen 241 includes a power consumption graph 250 in the house when a normal increase in electricity charges is not considered, and a control plan graph 255 of the air conditioner 5. A daily power consumption prediction 251 is displayed from the integrated value of power consumption in the house. Further, the target period during which the power rate increases is indicated by an arrow 252.
　制御計画グラフ２５５では、通常の電気料金の上昇を考慮しないエアコン５の設定温度グラフを示す。このグラフは手順１０２で生成した情報を用いている。 The control plan graph 255 shows a set temperature graph of the air conditioner 5 that does not take into account a normal increase in electricity charges. This graph uses information generated in step 102.
　画面２４２の詳細を図１７に示す。画面２４２は、通常の電気料金の上昇を考慮した場合の宅内の消費電力グラフ２６０と、エアコン５の制御計画グラフ２６５から成っている。宅内の消費電力の積算値から一日の消費電力量予測２６１を表示している。また電力料金が上昇する対象期間を矢印２５２で図示している。 Details of the screen 242 are shown in FIG. The screen 242 includes a power consumption graph 260 in the house when a normal increase in electricity charges is considered, and a control plan graph 265 of the air conditioner 5. A daily power consumption prediction 261 is displayed from the integrated value of power consumption in the house. Further, the target period during which the power rate increases is indicated by an arrow 252.
　制御計画グラフ２６５では、通常の電気料金の上昇を考慮しないエアコン５の設定温度グラフを示す。このグラフは手順１０２で生成した情報を用いている。 The control plan graph 265 shows a set temperature graph of the air conditioner 5 that does not take into account a normal increase in electricity charges. This graph uses information generated in step 102.
　対象期間２５２の間、グラフ２５５と比較するとグラフ２６５の設定温度が高い。これは、最適抑制可能快適度の分、快適度を下げても良いため、設定温度を上げる計画となっている。設定温度を上げたことで、グラフ２６０の対象期間２５２の間の消費電力が、グラフ２５０と比較して、下がっている。 During the target period 252, the set temperature of the graph 265 is higher than that of the graph 255. This is because the comfort level may be lowered by the degree of optimum restrainable comfort level, so the set temperature is planned to be raised. By increasing the set temperature, the power consumption during the target period 252 of the graph 260 is lower than that of the graph 250.
　ユーザは画面２４０を見ることで、電力使用量への影響範囲を容易に把握できる。 The user can easily grasp the range of influence on the power consumption by looking at the screen 240.
　手順４１１の詳細について、図１８を用いて説明する。図１８は、手順４１１の詳細を表すフローチャートである。 Details of the procedure 411 will be described with reference to FIG. FIG. 18 is a flowchart showing details of the procedure 411.

　手順５０１で、電気料金が上昇している対象期間２５２が終了したと判断できた場合、制御部２０は、対象期間２５２の間にユーザが在室していたかどうかを判断する（５０２）。ユーザの在室を確認するために、手順４１０で収集した赤外線センサの情報を確認して、対象期間２５２の間に人が居ると判断できる閾値を超えている場合に在室と判断する。 When it is determined in the procedure 501 that the target period 252 in which the electricity rate is increasing has ended, the control unit 20 determines whether or not the user is present during the target period 252 (502). In order to confirm the presence of the user, the information of the infrared sensor collected in step 410 is confirmed, and it is determined that the user is in the room when the threshold that can be determined that there is a person during the target period 252 is exceeded.
　手順５０２で、在室していないと判断した場合は、データを蓄積する必要がないため処理を終了する。 If it is determined in step 502 that the user is not in the room, the process is terminated because there is no need to accumulate data.
　手順５０２で、在室していると判断した場合、制御部２０は、デマンドレスポンス情報の確認をしたかどうか判断する（５０３）。判断のために手順４０５の確認がユーザの操作によってなされたか否かを基準とする。 When it is determined in step 502 that the user is in the room, the control unit 20 determines whether the demand response information has been confirmed (503). For the determination, it is based on whether or not the confirmation of the procedure 405 has been made by a user operation.
　手順５０３で、確認がされなかったと判断した場合は、ユーザはデマンドレスポンス情報を意識しなかったものとして、データを蓄積せずに処理を終了する。 If it is determined in step 503 that confirmation has not been made, it is assumed that the user has not been aware of demand response information, and the process ends without accumulating data.
　手順５０３で、確認されたと判断した場合は、制御部２０は、図４に示すデータテーブルに、抑制可能快適度１１０、電気料金差分１２０、対象期間１２１を登録する（５０５）。 When it is determined in step 503 that the information has been confirmed, the control unit 20 registers the restrainable comfort level 110, the electricity rate difference 120, and the target period 121 in the data table shown in FIG. 4 (505).

Can be.
　また、センサ４によってユーザが室内に居るかどうかを確認することによって、ユーザが不在の場合の状況を学習することを防ぎ、ユーザの意図を反映したデータを学習していくことができる。 Also, by checking whether the user is in the room by the sensor 4, it is possible to prevent learning of the situation when the user is absent, and to learn data reflecting the user's intention.

　次に計画管理サーバ１５は、最適抑制可能快適度を用いて計画を生成する（６０２）。 Next, the plan management server 15 generates a plan using the optimal degree of comfort that can be suppressed (602).
　計画管理サーバ１５は、生成した計画を対象となる住宅へ通信路３を介して送信する（６０３）。 The plan management server 15 transmits the generated plan to the target house via the communication path 3 (603).

　更新が完了したか、手順７０１の確認の結果、新しい計画が届いていないと判断した場合は、最新の計画を参照して、電気機器の制御を実行するタイミングかどうか判断する（７０３）。 If it is determined that the update has been completed or the new plan has not arrived as a result of the confirmation in step 701, it is determined whether or not it is time to execute control of the electrical device with reference to the latest plan (703).
　手順７０３の判断の結果、電気機器の制御を実行する場合は、記録された計画の内容に従って、電気機器を制御する（７０４）。 As a result of the determination in step 703, when the electric device is to be controlled, the electric device is controlled according to the contents of the recorded plan (704).
