　続いて、規則生成装置４０の動作について説明する。 Subsequently, the operation of the rule generation device 40 will be described.
　始めに、規則生成装置４０で、空調機群５０毎に、消費電力の削減に寄与する操作の事例を収集する事例収集処理の動作について説明する。予め定めた時間毎（例えば、１時間毎）に、規則生成装置４０の制御部４３は、図５のフローチャートに示す事例収集処理を実行する。 First, the operation of the case collection process for collecting case examples of operations that contribute to the reduction of power consumption for each air conditioner group 50 by the rule generation device 40 will be described. At every predetermined time (for example, every hour), the control unit 43 of the rule generation device 40 executes a case collection process shown in the flowchart of FIG.
　まず、制御部４３（情報取得部４０１）は、各コントローラ１０から、コントローラ１０が保持している空調機群５０に関する最新の各種情報を取得し、情報格納部４０２に記憶する（ステップＳ１０１）。具体的には、制御部４３は、インターネットＮ２を介して、各コントローラ１０に情報取得要求を送信する。情報取得要求を受信した各コントローラ１０の制御部１４は、電力ＤＢ１３１から電力情報、空調機ＤＢ１３２から各空調機３０の運転情報、環境ＤＢ１３３から各空調機３０の人数情報を取得して、規則生成装置４０に送信する。 First, the control part 43 (information acquisition part 401) acquires the latest various information regarding the air conditioner group 50 which the controller 10 hold | maintains from each controller 10, and memorize | stores it in the information storage part 402 (step S101). Specifically, the control unit 43 transmits an information acquisition request to each controller 10 via the Internet N2. The control unit 14 of each controller 10 that has received the information acquisition request acquires the power information from the power DB 131, the operation information of each air conditioner 30 from the air conditioner DB 132, and the number information of each air conditioner 30 from the environment DB 133, thereby generating a rule Transmit to device 40.
　続いて、制御部４３（検出部４０３）は、空調機群５０を１つ選択する（ステップＳ１０２）。以下の説明では、ステップＳ１０２で選択した空調機群５０を選択空調機群５０とも表記する。 Subsequently, the control unit 43 (detection unit 403) selects one air conditioner group 50 (step S102). In the following description, the air conditioner group 50 selected in step S102 is also referred to as a selected air conditioner group 50.
　続いて、制御部４３（検出部４０３）は、情報格納部４０２から選択空調機群５０の最新の電力情報を取得し、その電力情報が示す消費電力が、前回取得した選択空調機群５０の電力情報が示す消費電力から、閾値以上（例えば、１０パーセント以上）削減されているか否かを判別する（ステップＳ１０３）。 Subsequently, the control unit 43 (detection unit 403) acquires the latest power information of the selected air conditioner group 50 from the information storage unit 402, and the power consumption indicated by the power information indicates the previously acquired selected air conditioner group 50. It is determined whether or not the power consumption indicated by the power information is reduced by more than a threshold (for example, 10% or more) (step S103).
　削減されていないと判別した場合（ステップＳ１０３；Ｎｏ）、この選択空調機群５０では、消費電力を削減する操作はなされていないこととなり、処理はステップＳ１０７に移る。 If it is determined that it has not been reduced (step S103; No), the selected air conditioner group 50 has not been operated to reduce power consumption, and the process moves to step S107.
　一方、削減されていると判別した場合（ステップＳ１０３；Ｙｅｓ）、制御部４３（事例収集部４０４）は、選択空調機群５０を構成する各空調機３０の最新の運転情報と前回取得した運転情報とを情報格納部４０２から取得して比較し、運転情報が変更された（即ち、操作された）空調機３０を特定する（ステップＳ１０４）。なお、以下の説明では、ステップＳ１０４で特定した空調機３０を操作空調機３０とも表記する。 On the other hand, when it is determined that the amount has been reduced (step S103; Yes), the control unit 43 (example collection unit 404) displays the latest operation information of each air conditioner 30 configuring the selected air conditioner group 50 and the operation acquired last time. The information is acquired from the information storage unit 402 and compared, and the air conditioner 30 in which the operation information is changed (that is, operated) is specified (step S104). In the following description, the air conditioner 30 identified in step S104 is also referred to as an operation air conditioner 30.
　そして、制御部４３（事例収集部４０４）は、操作空調機３０の最新の環境情報を、選択空調機群５０を構成する他の空調機３０（即ち、操作されなかった空調機３０）の最新の環境情報と比較し、両者で違いが有るか否かを判別する（ステップＳ１０５）。なお、制御部４３は、環境情報のうち人数情報については、人数差が閾値（例えば２）以下の場合は、環境情報に違いは無いと判別してもよい。 Then, the control unit 43 (the case collection unit 404) uses the latest environment information of the operation air conditioner 30 as the latest information of the other air conditioners 30 (that is, the air conditioners 30 that have not been operated) constituting the selected air conditioner group 50. To determine whether there is a difference between the two (step S105). Note that the controller 43 may determine that there is no difference in the environmental information when the difference in the number of persons is equal to or less than a threshold (for example, 2) in the environmental information.
　環境情報に違いが無いと判別した場合（ステップＳ１０５；Ｎｏ）、ステップＳ１０７に処理は移る。一方、環境情報に違いが有ると判別した場合（ステップＳ１０５；Ｙｅｓ）、操作空調機３０でなされた操作は、その周囲の環境に応じて、省エネ目的を目的としてなされた操作（省エネ操作）となる。従って、制御部４３（事例収集部４０４）は、その省エネ操作を示す省エネ操作情報を、環境情報と対応付けて事例情報として事例格納部４０５に格納する（ステップＳ１０６）。 If it is determined that there is no difference in the environment information (step S105; No), the process proceeds to step S107. On the other hand, when it is determined that there is a difference in the environmental information (step S105; Yes), the operation performed in the operation air conditioner 30 is different from the operation performed for the purpose of energy saving (energy saving operation) according to the surrounding environment. Become. Therefore, the control unit 43 (case collection unit 404) stores the energy saving operation information indicating the energy saving operation in the case storage unit 405 as case information in association with the environment information (step S106).
　続いて、制御部４３（事例収集部４０４）は、ステップＳ１０２で全ての空調機群５０を選択したか否かを判別する（ステップＳ１０７）。選択していない場合（ステップＳ１０７；Ｎｏ）、処理はステップＳ１０２に移り、未選択の空調機群５０を選択して、事例情報を収集する処理を繰り返す。全ての空調機群５０を選択した場合、事例収集処理は終了する。 Subsequently, the control unit 43 (case collection unit 404) determines whether or not all the air conditioner groups 50 have been selected in step S102 (step S107). If not selected (step S107; No), the process proceeds to step S102, the unselected air conditioner group 50 is selected, and the process of collecting case information is repeated. When all the air conditioner groups 50 are selected, the case collection process ends.
　続いて、上述した事例収集処理について、例を挙げて説明する。図６は、９台の空調機３０「Ａ」～「Ｉ」からなる空調機群５０が配置された空調対象空間の平面図を示す。 Subsequently, the case collection process described above will be described with an example. FIG. 6 is a plan view of the air-conditioning target space in which the air conditioner group 50 including nine air conditioners 30 “A” to “I” is arranged.
　また、図７は、ステップＳ１０１で最新の情報を取得する直前（省エネ操作前）の、空調機３０「Ａ」～「Ｉ」からなる空調機群５０の電力情報と、各空調機３０「Ａ」～「Ｉ」の運転情報及び周囲の環境情報と、を示す図である。なお、環境情報のうち、窓フラグと出入口フラグは、それぞれ、空調機３０が窓に近いか、出入り口に近いかを示す情報であり、場所情報で設定されている。なお、窓フラグ「０」、出入口フラグ「０」は、窓、出入口に空調機３０が近くないことを示す。窓フラグ「１」、出入口フラグ「１」は、窓、出入口に空調機３０が近くにあることを示す。 FIG. 7 shows the power information of the air conditioner group 50 including the air conditioners 30 “A” to “I” and the air conditioners 30 “A” immediately before acquiring the latest information in step S 101 (before the energy saving operation). It is a figure which shows the driving | operation information and surrounding environmental information of "I". Of the environmental information, the window flag and the entrance / exit flag are information indicating whether the air conditioner 30 is close to the window or the entrance / exit, and are set by the location information. The window flag “0” and the entrance / exit flag “0” indicate that the air conditioner 30 is not close to the window / entrance. The window flag “1” and the entrance / exit flag “1” indicate that the air conditioner 30 is close to the window / entrance / exit.
　また、図８は、ステップＳ１０１で取得した空調機３０「Ａ」～「Ｉ」からなる空調機群５０の最新の電力情報と、各空調機３０「Ａ」～「Ｉ」の最新の運転情報及び周囲の環境情報と、を示す図である。 FIG. 8 shows the latest power information of the air conditioner group 50 composed of the air conditioners 30 “A” to “I” acquired in step S101 and the latest operation information of the air conditioners 30 “A” to “I”. It is a figure which shows surrounding environment information.
　ここで、この９台の空調機３０「Ａ」～「Ｉ」からなる空調機群５０を、事例収集処理のステップＳ１０２で選択した場合を考える。この場合、図８に示す最新の電力情報が示す消費電力は、図７に示す前回の電力情報が示す消費電力から削減されているため、ステップＳ１０３では「Ｙｅｓ」と判別される。 Here, consider a case where the air conditioner group 50 including the nine air conditioners 30 “A” to “I” is selected in step S102 of the case collection process. In this case, since the power consumption indicated by the latest power information shown in FIG. 8 is reduced from the power consumption indicated by the previous power information shown in FIG. 7, “Yes” is determined in step S103.
　また、図７と図８とで運転状態を比較すると、６台の空調機「Ｄ」～「Ｉ」は運転状態が前回から変更されているので、ステップＳ１０４で操作空調機３０であると特定される。 Further, comparing the operating state between FIG. 7 and FIG. 8, since the operating state of the six air conditioners “D” to “I” has been changed from the previous time, the operating air conditioner 30 is identified in step S104. Is done.
　そして、操作空調機３０「Ｄ」～「Ｉ」とそれ以外の空調機３０「Ａ」～「Ｂ」とでは、図８に示す環境情報に違いが有るため（ステップＳ１０５；Ｙｅｓ）、事例情報が収集される（ステップＳ１０６）。具体的には、設定温度を１℃下げる操作がなされた空調機３０「Ｄ」～「Ｆ」、「Ｈ」と、操作空調機３０でない空調機３０「Ａ」～「Ｃ」とを比較すると、空調機３０「Ｄ」～「Ｆ」、「Ｈ」では窓フラグが「０」であるという違いがあるため、「窓に近くない空調機３０の暖房設定温度を１℃下げる」ことを示す事例情報が収集される。 Since the environmental information shown in FIG. 8 is different between the operation air conditioners 30 “D” to “I” and the other air conditioners 30 “A” to “B” (step S105; Yes), the case information Are collected (step S106). Specifically, when the air conditioners 30 “D” to “F” and “H” that have been operated to lower the set temperature by 1 ° C. are compared with the air conditioners 30 “A” to “C” that are not the operation air conditioners 30, , Because there is a difference that the window flag is “0” in the air conditioners 30 “D” to “F” and “H”, it indicates that “the heating set temperature of the air conditioner 30 not close to the window is lowered by 1 ° C.” Case information is collected.
　また、運転停止の操作がなされた空調機３０「Ｇ」と、操作空調機３０でない空調機３０「Ａ」～「Ｃ」とを比較すると、空調機３０「Ｇ」では周囲の人数が「１」であるという違いがあるため、「周囲の人数が１人の空調機３０の運転を停止する」ことを示す事例情報が収集される。 Further, when the air conditioner 30 “G” in which the operation is stopped is compared with the air conditioners 30 “A” to “C” that are not the operation air conditioner 30, the number of people around the air conditioner 30 “G” is “1”. Therefore, case information indicating that “the number of people in the surroundings stops the operation of one air conditioner 30” is collected.
　また、設定温度を２℃下げる操作がなされた空調機３０「Ｉ」と、操作空調機３０でない空調機３０「Ａ」～「Ｃ」とを比較すると、空調機３０「Ｉ」では出入口フラグ「１」であるという違いがあるため、「出入口に近い空調機３０の設定温度を１℃下げる」ことを示す事例情報が収集される。 Further, when the air conditioner 30 “I” operated to lower the set temperature by 2 ° C. and the air conditioners 30 “A” to “C” that are not the operation air conditioner 30 are compared, the air conditioner 30 “I” has an entrance / exit flag “ Since there is a difference of “1”, case information indicating that “the set temperature of the air conditioner 30 close to the entrance / exit is lowered by 1 ° C.” is collected.
　このように、事例収集処理により、異なる空調対象空間に設置されている空調機群５０それぞれについて、周囲の環境に応じてなされた、消費電力の削減に寄与する省エネ操作の事例が収集される。 As described above, the case collection process collects the examples of the energy saving operations that are made in accordance with the surrounding environment and contribute to the reduction of power consumption for each of the air conditioner groups 50 installed in different air-conditioning target spaces.
　続いて、事例収集処理で収集した事例情報から、省エネを促進する空調機３０の運転規則を生成する規則生成処理について説明する。予め定めた時間毎（例えば、日付が変わるタイミング）に、規則生成装置４０の制御部４３（規則生成部４０６）は、図９のフローチャートに示す規則生成処理を実行する。 Subsequently, a rule generation process for generating an operation rule of the air conditioner 30 that promotes energy saving from the case information collected in the case collection process will be described. At every predetermined time (for example, when the date changes), the control unit 43 (rule generation unit 406) of the rule generation device 40 executes the rule generation processing shown in the flowchart of FIG.
　まず、制御部４３は、規則格納部４０７に格納されている規則情報を消去する（ステップＳ２０１）。 First, the control unit 43 deletes the rule information stored in the rule storage unit 407 (step S201).
　続いて、制御部４３は、事例格納部４０５から、最近（例えば、直近２週間以内）に収集された事例情報を抽出する（ステップＳ２０２）。 Subsequently, the control unit 43 extracts case information collected recently (for example, within the last two weeks) from the case storage unit 405 (step S202).
　続いて、制御部４３は、ステップＳ２０２で抽出した事例情報の中から、閾値以上（例えば１０以上）存在する同じ内容の事例情報を特定する（ステップＳ２０３）。なお、制御部４３は、抽出した事例情報の中から、予め定めた割合以上（例えば１０パーセント以上）存在する同じ内容の事例情報を特定してもよい。 Subsequently, the control unit 43 identifies the case information having the same content that exists above the threshold (for example, 10 or more) from the case information extracted at Step S202 (Step S203). In addition, the control part 43 may specify the case information of the same content which exists more than a predetermined ratio (for example, 10 percent or more) from the extracted case information.
　続いて、制御部４３は、特定した事例情報を、省エネを促進する空調機３０の運転規則として、規則格納部４０７に格納する（ステップＳ２０４）。以上で規則作成処理は終了する。 Subsequently, the control unit 43 stores the specified case information in the rule storage unit 407 as an operation rule of the air conditioner 30 that promotes energy saving (step S204). This completes the rule creation process.
　続いて、作成した運転規則を空調機３０の運転スケジュールに適用して送信する規則適用処理について説明する。上述した規則作成処理が完了に応答して、規則生成装置４０の制御部４３は、図１０のフローチャートに示す規則適用処理を実行する。 Subsequently, a rule application process for applying and transmitting the created operation rule to the operation schedule of the air conditioner 30 will be described. In response to the completion of the rule creation process described above, the control unit 43 of the rule generation device 40 executes the rule application process shown in the flowchart of FIG.
　まず、制御部４３（規則適用部４０９）は、空調機群５０を１つ選択する（ステップＳ３０１）。そして、制御部４３は、規則格納部４０７に格納されている運転規則に基づいて、選択した空調機群５０を構成する各空調機３０のスケジュールを変更する（ステップＳ３０２）。 First, the control unit 43 (rule application unit 409) selects one air conditioner group 50 (step S301). And the control part 43 changes the schedule of each air conditioner 30 which comprises the selected air conditioner group 50 based on the driving | running rule stored in the rule storage part 407 (step S302).
　そして、制御部４３は、変更した空調機群５０のスケジュール情報を、この空調機群５０を管理するコントローラ１０に送信する（ステップＳ３０３）。コントローラ１０の制御部１４は、受信したスケジュール情報をスケジュールＤＢ１３４に格納し、以後はこのスケジュール情報に基づいて、空調機群５０の運転を制御する。 And the control part 43 transmits the schedule information of the changed air conditioner group 50 to the controller 10 which manages this air conditioner group 50 (step S303). The controller 14 of the controller 10 stores the received schedule information in the schedule DB 134, and thereafter controls the operation of the air conditioner group 50 based on the schedule information.
　続いて、制御部４３は、ステップＳ３０１で全ての空調機群５０を選択したか否かを判別する（ステップＳ３０４）。選択していない場合（ステップＳ３０４；Ｎｏ）、処理はステップＳ３０１に移り、未選択の空調機群５０を選択して、運転規則を用いてスケジュール情報を変更してコントローラ１０に送信する処理を繰り返す。全ての空調機群５０を選択した場合、規則適用処理は終了する。 Subsequently, the control unit 43 determines whether or not all the air conditioner groups 50 have been selected in Step S301 (Step S304). If it has not been selected (step S304; No), the process proceeds to step S301, the unselected air conditioner group 50 is selected, the schedule information is changed using the operation rule, and the process of transmitting to the controller 10 is repeated. . When all the air conditioner groups 50 are selected, the rule application process ends.
　続いて、規則適用処理でスケジュールが変更される処理（ステップＳ３０２）の具体例について説明する。図１１は、４台の空調機３０「Ｊ」～「Ｍ」からなる空調機群５０の９時から１８時の運転スケジュールを示すスケジュール情報と、周囲の環境情報（窓フラグ、出入口フラグ）とを示す図である。 Subsequently, a specific example of the process (step S302) in which the schedule is changed by the rule application process will be described. FIG. 11 shows schedule information indicating an operation schedule from 9:00 to 18:00 of an air conditioner group 50 including four air conditioners 30 “J” to “M”, and surrounding environment information (window flag, entrance / exit flag) FIG.
　例えば、図１１に示すスケジュール情報に、「窓に近くない空調機３０の暖房設定温度を１℃下げる」運転規則を適用すると、図１２に示すように、窓フラグ「０」の空調機３０「Ｋ」の設定温度は、「２２℃」から「２１℃」に変更される。 For example, when the operation rule “decrease the heating set temperature of the air conditioner 30 that is not close to the window by 1 ° C.” is applied to the schedule information shown in FIG. 11, the air conditioner 30 “with the window flag“ 0 ”as shown in FIG. The set temperature of “K” is changed from “22 ° C.” to “21 ° C.”.
　また、例えば、図１１に示すスケジュール情報に、「出入口に近い空調機３０の暖房設定温度を１℃下げる」運転規則を適用すると、図１２に示すように、出入口フラグ「１」の空調機３０「Ｌ」の設定温度は、「２２℃」から「２１℃」に変更される。 Further, for example, when the operation rule “decrease the heating set temperature of the air conditioner 30 close to the entrance / exit by 1 ° C.” is applied to the schedule information shown in FIG. 11, the air conditioner 30 with the entrance / exit flag “1” as shown in FIG. The set temperature of “L” is changed from “22 ° C.” to “21 ° C.”.
　また、例えば、図１１に示すスケジュール情報に、「周囲の人数が１人の空調機３０の運転を停止する」運転規則を適用すると、図１２に示すように、人数「１」の空調機３０「Ｍ」の運転は停止される。 Further, for example, when the operation rule “stop operation of the air conditioner 30 by one person” is applied to the schedule information shown in FIG. 11, the air conditioner 30 of the number “1” as shown in FIG. 12. The operation of “M” is stopped.
　このように、本実施形態に係る規則生成装置４０では、コントローラ１０から取得した各空調機３０に関する情報から周囲の環境に応じてなされた省エネ操作が検出され、その環境とともに事例情報として収集される。そして、収集された事例情報から、省エネを促進するための運転規則が作成される。従って、複数の空調機３０から、広く事例情報を収集して運転規則を作成するため、従来よりも空調機３０を適切に省エネ制御することが可能となる。 As described above, in the rule generation device 40 according to the present embodiment, the energy-saving operation performed according to the surrounding environment is detected from the information regarding each air conditioner 30 acquired from the controller 10, and collected as case information together with the environment. . And the operation rule for promoting energy saving is created from the collected case information. Accordingly, since the case information is widely collected from the plurality of air conditioners 30 and the operation rules are created, it is possible to perform energy saving control of the air conditioner 30 more appropriately than before.
　また、本実施形態によれば、作成した運転規則を用いて、各空調機３０のスケジュール情報が更新されるため、更新されたスケジュール情報を用いて、各空調機３０を適切に省エネ制御することが可能となる。 Moreover, according to this embodiment, since the schedule information of each air conditioner 30 is updated using the created operation rule, the energy saving control of each air conditioner 30 is appropriately performed using the updated schedule information. Is possible.
　また、本実施形態によれば、直近に収集した事例情報から運転規則を作成するため、現在の時期に応じた適切な運転規則を作成することができる。 Further, according to the present embodiment, since the operation rule is created from the latest collected case information, it is possible to create an appropriate operation rule according to the current time.
　また、本実施形態によれば、省エネの事例情報をすぐには運転規則としては採用せずに、閾値以上の同内容の事例情報を収集されている場合に運転規則として採用するため、普遍的な運転規則を作成することが可能となる。 Also, according to this embodiment, energy saving case information is not immediately adopted as driving rules, but is adopted as driving rules when case information with the same content above a threshold is collected. It is possible to create a proper driving rule.
　また、本実施形態によれば、それぞれが異なる空調機群５０を管理する複数のコントローラ１０毎に、取得した情報に基づいて省エネ操作を検出して、事例情報を収集する。そのため、様々な使われ方をしている空調機３０から事例情報を広く収集することができ、より適切な運転規則を作成することが可能となる。 Further, according to the present embodiment, the energy saving operation is detected based on the acquired information and the case information is collected for each of the plurality of controllers 10 that manage different air conditioner groups 50. Therefore, case information can be widely collected from the air conditioners 30 that are used in various ways, and more appropriate operation rules can be created.

Various methods can be adopted. For example, the rule generation device 40 may transmit the created operation rule directly to the controller 10, and the controller 10 may update the operation schedule of each air conditioner 30 to be managed based on the received operation rule. In addition, when the operation rule “stop operation of the air conditioner 30 by one person in the surroundings” is received, the control unit 14 of the controller 10 sequentially monitors the number of persons around each air conditioner 30 and the number of persons is determined.
