　最初に電力管理システムの立ち上げ動作について説明する。まず、コントローラ３および各電気機器７に電源が投入されると、各電気機器７はコントローラ３に対して機器情報を通知する。コントローラ３は、各電気機器７から機器情報を取得した後、管理サーバ２に機器構成情報を送信する。その後、管理サーバ２は、コントローラ３から取得した機器構成情報を参照し、同一の住居ＩＤの機器構成情報が未登録の場合、上記機器構成情報を新規に登録する。一方、同一の住居ＩＤの機器構成情報が既に登録されている場合、管理サーバ２は、受信した内容に機器構成情報を更新する。 First, the startup operation of the power management system will be described. First, when the controller 3 and each electrical device 7 are powered on, each electrical device 7 notifies the controller 3 of device information. The controller 3 acquires the device information from each electrical device 7 and then transmits the device configuration information to the management server 2. Thereafter, the management server 2 refers to the device configuration information acquired from the controller 3, and newly registers the device configuration information when the device configuration information of the same residence ID is not registered. On the other hand, when the device configuration information of the same residence ID has already been registered, the management server 2 updates the device configuration information with the received content.
　続いて、住居８間の電力使用量情報の提供について説明する。まず、分電盤５は、コントローラ３に総電力使用量の情報を通知する。その後、コントローラ３は、電力使用量情報を管理サーバ２に送信する。管理サーバ２は、上記電力使用量情報を電力使用量情報記憶部２４２に書き込む。その後、管理サーバ２は、上記電力使用量情報の住居ＩＤに対応する機器構成情報を機器構成情報記憶部２４１から読み出し、同一の機器構成を持つ住居ＩＤを機器構成情報記憶部２４１から検索する。管理サーバ２は、該当した住居ＩＤについて、上記電力使用量情報と同じ年月の電力使用量情報を参照する。その後、管理サーバ２は、該当した住居ＩＤの住居８を比較対象住居に選定し、自住居の電力使用量情報（総電力使用量情報、年月情報）および比較対象住居の電力使用量情報をＷｅｂコンテンツへ反映する。 Next, the provision of power usage information between the houses 8 will be described. First, the distribution board 5 notifies the controller 3 of information on the total power consumption. Thereafter, the controller 3 transmits power usage information to the management server 2. The management server 2 writes the power usage information in the power usage information storage unit 242. Thereafter, the management server 2 reads out the device configuration information corresponding to the residence ID of the power usage information from the device configuration information storage unit 241 and searches the device configuration information storage unit 241 for a residence ID having the same device configuration. The management server 2 refers to the power usage information of the same year as the power usage information for the corresponding residence ID. Thereafter, the management server 2 selects the residence 8 having the corresponding residence ID as a comparison target residence, and uses the power usage information (total power usage information, year / month information) of the own residence and the power usage information of the comparison target residence. Reflect to Web content.
　例えば、基準構成選択部２２１１に住居ＩＤ「０ｘ０００１」が与えられると、基準構成選択部２２１１は、機器構成情報記憶部２４１を参照して、受け取った住居ＩＤ「０ｘ０００１」を含む機器構成情報に含まれる機器構成を基準構成として選択する。すなわち、基準構成選択部２２１１は、住居ＩＤ「０ｘ０００１」に対応する第１の住居８１の機器構成を基準構成として取得する。 For example, when the residence ID “0x0001” is given to the reference configuration selection unit 2211, the reference configuration selection unit 2211 refers to the device configuration information storage unit 241, and is included in the device configuration information including the received residence ID “0x0001”.

The power management system according to the second embodiment is different from the power management system according to the first embodiment in that another residence 8 having the same combination of electrical devices 7 having a large rated power is selected as a comparison target residence. Hereinafter, the power management system of the present embodiment will be described with reference to FIG. 1 and FIGS. In addition, about the component similar to the power management system of Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態の管理サーバ２において、第１の記憶装置２４は、図９に示すように、機器種別ごとに基準定格電力を予め記憶する基準定格電力情報記憶部２４３を備えている。 In the management server 2 of the present embodiment, the first storage device 24 includes a reference rated power information storage unit 243 that stores a reference rated power in advance for each device type, as shown in FIG.
　基準定格電力は、図１０に示すように、機器種別（エアコン、洗濯機、冷蔵庫など）ごとに規定されている。例えば同じエアコンであっても、メーカや機種（品番）によって定格電力が異なるが、代表的な値によって基準定格電力が決定されている。基準定格電力の決定方法については特に限定されず、例えば、各住居８から得られる機器構成情報に含まれている定格電力の平均値を基準定格電力とする方法、今年度に各メーカから発売された機種の平均値を基準定格電力とする方法または前年度に最もよく売れた機種のトップ５の平均値を基準定格電力とする方法などがある。 The standard rated power is specified for each device type (air conditioner, washing machine, refrigerator, etc.) as shown in FIG. For example, even if the air conditioners are the same, the rated power varies depending on the manufacturer and model (part number), but the standard rated power is determined by a representative value. The method for determining the reference rated power is not particularly limited. For example, a method in which the average value of the rated power included in the device configuration information obtained from each residence 8 is used as the reference rated power. There are a method of using the average value of the models that have been used as the standard rated power, and a method of using the average value of the top five models that sold best in the previous year as the standard rated power.
　本実施形態の選定部２２１は、各住居側管理装置１（図１参照）の機器構成情報を用いて、基準定格電力が規定値以上である電気機器７（図１参照）の組み合わせが同一である他の住居８を比較対象住居として選定する。規定値は、予め設定された値である。 The selection unit 221 of the present embodiment uses the device configuration information of each residential management device 1 (see FIG. 1), and the combination of the electric devices 7 (see FIG. 1) whose reference rated power is equal to or higher than a specified value is the same. A certain other residence 8 is selected as a comparison subject residence. The specified value is a preset value.
　すなわち、本実施形態では、第１の記憶装置（情報記憶装置）２４は、機器種別ごとに基準定格電力を記憶する基準定格電力情報記憶部２４３を備える。本実施形態では、所定の機器種別は、基準定格電力が規定値以上の機器種別である。よって、所定の一致基準は、基準定格電力が規定値以上の機器種別に対応する電気機器７の数である。 That is, in the present embodiment, the first storage device (information storage device) 24 includes a reference rated power information storage unit 243 that stores the reference rated power for each device type. In the present embodiment, the predetermined device type is a device type whose reference rated power is a specified value or more. Therefore, the predetermined coincidence criterion is the number of electrical devices 7 corresponding to the device type whose reference rated power is a specified value or more.
　次に、本実施形態に係る電力管理システムにおいて、住居８間の電力使用量情報の提供について説明する。まず、実施形態１と同様に、コントローラ３（図１参照）が電力使用量情報を管理サーバ２に送信し、管理サーバ２が電力使用量情報を電力使用量情報記憶部２４２に書き込む。また、管理サーバ２は、各機器種別の基準定格電力情報を読み出し、基準定格電力が規定値以上である機器種別を全て記憶する。その後、管理サーバ２は、上記電力使用量情報の住居ＩＤに対応する機器構成情報を読み出し、基準定格電力が規定値以上である機器種別の電気機器７について同一の組み合わせを持つ住居ＩＤを機器構成情報記憶部２４１から検索する。管理サーバ２は、該当した住居ＩＤについて、上記電力使用量情報と同じ年月の電力使用量情報を参照する。その後、管理サーバ２は、該当した住居ＩＤの住居８を比較対象住居に選定し、自住居の電力使用量情報（総電力使用量情報、年月情報）と比較対象住居の電力使用量情報とをＷｅｂコンテンツへ反映する。 Next, in the power management system according to this embodiment, provision of power usage information between the houses 8 will be described. First, as in the first embodiment, the controller 3 (see FIG. 1) transmits power usage information to the management server 2, and the management server 2 writes the power usage information in the power usage information storage unit 242. In addition, the management server 2 reads the reference rated power information for each device type, and stores all device types for which the reference rated power is greater than or equal to a specified value. Thereafter, the management server 2 reads the device configuration information corresponding to the residence ID of the power usage information, and sets the residence ID having the same combination for the electrical device 7 of the device type whose reference rated power is equal to or greater than the specified value. Search from the information storage unit 241. The management server 2 refers to the power usage information of the same year as the power usage information for the corresponding residence ID. Thereafter, the management server 2 selects the residence 8 having the corresponding residence ID as the comparison target residence, and uses the power usage information (total power usage information, year / month information) of the own residence and the power usage information of the comparison target residence. Is reflected in the Web content.
　次に、本実施形態に係る電力管理システムの使用例について図１１，１２を用いて説明する。図１１は、ある住居８（自住居８１）に対して４戸の他の住居８（他住居８２～８５）が存在する場合である。自住居８１には、機器種別「Ａ」である第１の電気機器７１が２台、機器種別「Ｂ」である第２の電気機器７２が１台、機器種別「Ｃ」である第３の電気機器７３が２台、機器種別「Ｄ」である第４の電気機器７４が２台の計７台の電気機器７が設置されている。なお、自住居８１には、機器種別「Ｅ」である第５の電気機器７５および機器種別「Ｆ」である第６の電気機器７６は設置されていない。 Next, usage examples of the power management system according to the present embodiment will be described with reference to FIGS. FIG. 11 shows a case where four other houses 8 (other houses 82 to 85) exist for a certain house 8 (own house 81). In the own residence 81, there are two first electric devices 71 having the device type “A”, one second electric device 72 having the device type “B”, and a third electric device 71 having the device type “C”. A total of seven electric devices 7 are installed, including two electric devices 73 and two fourth electric devices 74 of the device type “D”. In addition, in the own residence 81, the fifth electrical device 75 having the device type “E” and the sixth electrical device 76 having the device type “F” are not installed.
　例えば、基準構成選択部２２１１に住居ＩＤ「０ｘ０００１」が与えられると、基準構成選択部２２１１は、機器構成情報記憶部２４１を参照して、受け取った住居ＩＤ「０ｘ０００１」を含む機器構成情報に含まれる機器構成を基準構成として選択する。すなわち、基準構成選択部２２１１は、住居ＩＤ「０ｘ０００１」に対応する第１の住居８１の機器構成を基準構成として取得する。 For example, when the residence ID “0x0001” is given to the reference configuration selection unit 2211, the reference configuration selection unit 2211 refers to the device configuration information storage unit 241, and is included in the device configuration information including the received residence ID “0x0001”. Select the device configuration to be used as the reference configuration. That is, the reference configuration selection unit 2211 acquires the device configuration of the first residence 81 corresponding to the residence ID “0x0001” as the reference configuration.
　検索部２２１２は、基準構成選択部２２１１で選択された基準構成に基づいて検索処理を行う。検索処理では、検索部２２１２は、基準定格電力が規定値以上である機器種別に対応する電気機器７の数において、基準構成と同一である機器構成を示す機器構成情報を機器構成情報記憶部２４１から探す。 The search unit 2212 performs a search process based on the reference configuration selected by the reference configuration selection unit 2211. In the search process, the search unit 2212 displays device configuration information indicating the device configuration that is the same as the reference configuration in the number of electrical devices 7 corresponding to the device type whose reference rated power is equal to or greater than the specified value, and the device configuration information storage unit 241. Search from.
　例えば、規定値が５００Ｗである場合、基準定格電力が規定値を超えているのは、機器種別「Ａ」，「Ｂ」，「Ｃ」の３つである。 For example, when the specified value is 500 W, the reference rated power exceeds the specified value for three device types “A”, “B”, and “C”.
　よって、検索処理で比較される第１～第５の住居８１－８５の機器構成は、例えば、下表２のようになる。 Therefore, the device configurations of the first to fifth residences 81-85 compared in the search process are as shown in Table 2 below, for example.
Figure JPOXMLDOC01-appb-T000002
Figure JPOXMLDOC01-appb-T000002
　図１１および表２から明らかなように、第１の住居８１の機器構成（基準構成）は、機器種別Ａ－Ｃに対応する電気機器７の数において、第４の住居８４の機器構成と同一である。よって、検索部２２１２は、第４の住居８４に対応する機器構成情報を機器構成情報記憶部２４１から発見して、取得する。 As is clear from FIG. 11 and Table 2, the device configuration (reference configuration) of the first residence 81 is the same as the device configuration of the fourth residence 84 in the number of electrical devices 7 corresponding to the device types AC. It is. Therefore, the search unit 2212 finds and acquires the device configuration information corresponding to the fourth residence 84 from the device configuration information storage unit 241.
　住居識別子取得部２２１３は、検索処理において発見された機器構成情報に含まれる住居ＩＤ「０ｘ０００４」を取得する。そして、住居識別子取得部２２１３は、基準構成選択部２２１１に与えられた住居ＩＤ「０ｘ０００１」に、取得した住居ＩＤ「０ｘ０００４」を比較対象住居として関連付ける。 The residence identifier acquisition unit 2213 acquires the residence ID “0x0004” included in the device configuration information discovered in the search process. Then, the residence identifier acquisition unit 2213 associates the acquired residence ID “0x0004” with the residence ID “0x0001” given to the reference configuration selection unit 2211 as a comparison target residence.
　このように、規定値が５００Ｗである場合、図１２に示すように、第１～３の電気機器７１～７３が比較対象となる。管理サーバ２は、他住居８２～８５の機器構成情報から、第１の電気機器７１が２台、第２の電気機器７２が１台、第３の電気機器７３が２台である他の住居８を検索する。その結果、管理サーバ２は、他住居８４を比較対象住居に選定する。他住居８２，８３，８５は、第１～３の電気機器７１～７３の各台数が自住居８１と同一ではないため、比較対象住居には選定されない。 Thus, when the specified value is 500 W, the first to third electric devices 71 to 73 are to be compared as shown in FIG. Based on the device configuration information of the other residences 82 to 85, the management server 2 has two first electric devices 71, one second electric device 72, and two third electric devices 73. 8 is searched. As a result, the management server 2 selects the other residence 84 as a comparison target residence. The other residences 82, 83, and 85 are not selected as the comparison target residences because the number of the first to third electric devices 71 to 73 is not the same as that of the own residence 81.
　以上述べたように、本実施形態の電力管理システムでは、第１の記憶装置（情報記憶装置）２４は、機器種別ごとに基準定格電力を記憶する基準定格電力情報記憶部２４３を備える。検索部２２１２における所定の機器種別は、基準定格電力が規定値以上の機器種別である。すなわち、本実施形態では、検索部２２１２は、基準定格電力が規定値以上の機器種別に対応する電気機器７の数に基づいて、基準構成と機器構成とが一致しているか否かを判定する。 As described above, in the power management system of the present embodiment, the first storage device (information storage device) 24 includes the reference rated power information storage unit 243 that stores the reference rated power for each device type. The predetermined device type in the search unit 2212 is a device type whose reference rated power is a specified value or more. In other words, in the present embodiment, the search unit 2212 determines whether or not the reference configuration matches the device configuration based on the number of electrical devices 7 corresponding to the device type whose reference rated power is a specified value or more. .
　以上、本実施形態の電力管理システムによれば、基準定格電力が大きい電気機器７の組み合わせによって比較対象住居を選定することによって、電力使用量への影響度を考慮しながら、比較対象住居の選択肢を増やすことができる。 As described above, according to the power management system of the present embodiment, by selecting the comparison target residence by the combination of the electric devices 7 having a large reference rated power, it is possible to select the comparison target residence while considering the influence on the power consumption. Can be increased.
　なお、本実施形態の変形例として、管理サーバ２の選定部２２１は、基準定格電力を用いて比較対象住居を選定するのではなく、各電気機器７ごとに実測された電力（電力量）を定格電力とし、この定格電力が規定値以上である電気機器７の組み合わせが同一である他の住居８を比較対象住居として選定してもよい。また、選定部２２１は、各電気機器７の定格電力をそのまま用いて、比較対象住居を選定してもよい。以下の実施形態３，４においても同様である。 As a modification of the present embodiment, the selection unit 221 of the management server 2 does not select the comparison target residence using the reference rated power, but uses the electric power (power amount) measured for each electric device 7. Other houses 8 having the same combination of the electric devices 7 having the rated power equal to or higher than a specified value may be selected as the comparison target house. Moreover, the selection part 221 may select a comparison object residence, using the rated power of each electric equipment 7 as it is. The same applies to the following third and fourth embodiments.
　また、本実施形態の変形例として、選定部２２１は、定格電力が規定値以上である電気機器７の組み合わせではなく、定格電力が規定範囲内（下限値以上かつ上限値以下）である電気機器７の組み合わせが同一である他の住居８を比較対象住居として選定してもよい。 Further, as a modification of the present embodiment, the selection unit 221 is not a combination of the electric devices 7 whose rated power is equal to or higher than a specified value, but is an electric device whose rated power is within a specified range (lower limit value or higher and lower limit value or lower). You may select the other residence 8 in which the combination of 7 is the same as a comparison object residence.
　すなわち、本実施形態の電力管理システムでは、第１の記憶装置（情報記憶装置）２４は、機器種別ごとに基準定格電力を記憶する基準定格電力情報記憶部２４３を備え、さらに、検索部２２１２における所定の機器種別は、基準定格電力が規定範囲内の機器種別であってもよい。すなわち、検索部２２１２は、基準定格電力が規定範囲内の機器種別に対応する電気機器７の数に基づいて、基準構成と機器構成とが一致しているか否かを判定してもよい。 That is, in the power management system of the present embodiment, the first storage device (information storage device) 24 includes a reference rated power information storage unit 243 that stores the reference rated power for each device type, and further in the search unit 2212. The predetermined device type may be a device type whose reference rated power is within a specified range. That is, the search unit 2212 may determine whether or not the reference configuration matches the device configuration based on the number of electrical devices 7 whose reference rated power corresponds to the device type within the specified range.
　例えば、規定範囲が４００Ｗ以上９００Ｗ以下である場合、基準定格電力が規定範囲内であるのは機器種別「Ｂ」，「Ｃ」，「Ｄ」の３つである。 For example, when the specified range is 400 W or more and 900 W or less, there are three device types “B”, “C”, and “D” whose reference rated power is within the specified range.
　よって、検索処理で比較される第１～第５の住居８１－８５の機器構成は、例えば、下表３のようになる。 Therefore, the device configurations of the first to fifth residences 81-85 compared in the search process are as shown in Table 3 below, for example.
Figure JPOXMLDOC01-appb-T000003
Figure JPOXMLDOC01-appb-T000003
　図１１および表３から明らかなように、第１の住居８１の機器構成（基準構成）は、機器種別「Ｂ」，「Ｃ」，「Ｄ」にそれぞれ対応する電気機器７の数において、第３の住居８３の機器構成と同一である。よって、検索部２２１２は、第３の住居８３に対応する機器構成情報を機器構成情報記憶部２４１から発見して、取得する。 As is clear from FIG. 11 and Table 3, the device configuration (reference configuration) of the first residence 81 is the number of electrical devices 7 corresponding to the device types “B”, “C”, and “D”, respectively. 3 is the same as that of the housing 83. Therefore, the search unit 2212 finds and acquires the device configuration information corresponding to the third residence 83 from the device configuration information storage unit 241.
　住居識別子取得部２２１３は、検索処理において発見された機器構成情報に含まれる住居ＩＤ「０ｘ０００３」を取得する。そして、住居識別子取得部２２１３は、基準構成選択部２２１１に与えられた住居ＩＤ「０ｘ０００１」に、取得した住居ＩＤ「０ｘ０００３」を比較対象住居として関連付ける。 The residence identifier acquisition unit 2213 acquires the residence ID “0x0003” included in the device configuration information discovered in the search process. Then, the residence identifier acquisition unit 2213 associates the acquired residence ID “0x0003” with the residence ID “0x0001” given to the reference configuration selection unit 2211 as a comparison target residence.
　この点は以下の実施形態３，４においても同様である。例えば自住居にエアコンが設置されている場合、選定部２２１は、自住居と他の住居８との間でエアコンの台数が同じであり、他の住居８に設置されているエアコンの定格電力が自住居のエアコンとほぼ同じ大きさであるときは、上記の住居８を比較対象住居として選定する。一方、自住居と他の住居８との間でエアコンの台数が同じであっても、他の住居８に設置されているエアコンの定格電力が自住居のエアコンと大きく異なるときは、選定部２２１は、上記の住居８を比較対象住居として選定しない。また、選定部２２１は、他の住居８において、自住居の電気機器７と同じ型番の電気機器７が存在しなければ、比較対象住居として選定しないようにしてもよい。 This point is the same in the following third and fourth embodiments. For example, when an air conditioner is installed in the own residence, the selection unit 221 has the same number of air conditioners between the own residence and the other residence 8, and the rated power of the air conditioner installed in the other residence 8 is When the size of the air conditioner is approximately the same as that of the own residence, the above residence 8 is selected as a comparison residence. On the other hand, even if the number of air conditioners is the same between the own residence and the other residence 8, when the rated power of the air conditioner installed in the other residence 8 is significantly different from that of the own residence, the selection unit 221 Does not select the above-mentioned dwelling 8 as a dwelling for comparison. In addition, the selection unit 221 may not select the comparison residence as long as there is no electrical device 7 having the same model number as the electrical device 7 of the own residence in the other residence 8.
　（実施形態３）
　実施形態３に係る電力管理システムは、比較対象住居を選定することができなかった場合に規定値を大きくして、再度、比較対象住居を選定する点で、実施形態２に係る電力管理システムと相違する。以下、本実施形態の電力管理システムについて図１，９および図１３を用いて説明する。なお、実施形態２の電力管理システムと同様の構成要素については、同一の符号を付して説明を省略する。 (Embodiment 3)
The power management system according to the third embodiment is the same as the power management system according to the second embodiment in that the specified value is increased when the comparison target residence cannot be selected, and the comparison target residence is selected again. Is different. Hereinafter, the power management system of this embodiment will be described with reference to FIGS. In addition, about the component similar to the power management system of Embodiment 2, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態において、検索部２２１２は、所定の一致基準として、基準定格電力が規定値以上である機器種別に対応する電気機器７の数を採用する。また、検索部２２１２は、検索処理において基準構成と同一の機器構成を含む機器構成情報を機器構成情報記憶部２４１から発見できなければ、規定値を所定値だけ増加させて、再度、検索処理を行うように構成される。なお、所定値は、定数であってもよい。また、所定値は、検索処理の実行回数に依存する変数であってもよい。この場合、例えば、１回目の検索処理の規定値が３００Ｗである場合に、２回目の検索処理の規定値を５００Ｗ、３回目の検索処理の規定値を９００Ｗとすることができる。 In the present embodiment, the search unit 2212 employs the number of electrical devices 7 corresponding to the device type whose reference rated power is a specified value or more as a predetermined matching criterion. In addition, if the device configuration information including the same device configuration as the reference configuration cannot be found from the device configuration information storage unit 241 in the search processing, the search unit 2212 increases the specified value by a predetermined value and performs the search processing again. Configured to do. The predetermined value may be a constant. The predetermined value may be a variable that depends on the number of executions of the search process. In this case, for example, when the specified value of the first search process is 300 W, the specified value of the second search process can be set to 500 W, and the specified value of the third search process can be set to 900 W.
　すなわち、本実施形態の選定部２２１（図９参照）は、比較対象住居を選定することができなかった場合に、規定値をこれまでよりも大きくする。その後、選定部２２１は、基準定格電力が規定値以上である電気機器７（図１参照）の数を減らして比較対象住居を選定する。 That is, the selection unit 221 (see FIG. 9) of the present embodiment increases the specified value more than before when the comparison target residence cannot be selected. Thereafter, the selection unit 221 selects a comparison target residence by reducing the number of electrical devices 7 (see FIG. 1) whose standard rated power is greater than or equal to a specified value.
　次に、本実施形態に係る電力管理システムにおいて、住居８間の電力使用量情報の提供について説明する。まず、実施形態２と同様に、コントローラ３（図１参照）が電力使用量情報を管理サーバ２（図９参照）に送信し、管理サーバ２が電力使用量情報を電力使用量情報記憶部２４２（図９参照）に書き込む。また、管理サーバ２は、各機器種別の基準定格電力情報を読み出し、基準定格電力が規定値以上である機器種別を全て記憶する。その後、管理サーバ２は、上記電力使用量情報の住居ＩＤに対応する機器構成情報を読み出し、基準定格電力が規定値以上である機器種別の電気機器７について同一の組み合わせを持つ住居ＩＤを機器構成情報記憶部２４１（図９参照）から検索する。 Next, in the power management system according to this embodiment, provision of power usage information between the houses 8 will be described. First, as in the second embodiment, the controller 3 (see FIG. 1) transmits power usage information to the management server 2 (see FIG. 9), and the management server 2 sends the power usage information to the power usage information storage unit 242. Write to (see FIG. 9). In addition, the management server 2 reads the reference rated power information for each device type, and stores all device types for which the reference rated power is greater than or equal to a specified value. Thereafter, the management server 2 reads the device configuration information corresponding to the residence ID of the power usage information, and sets the residence ID having the same combination for the electrical device 7 of the device type whose reference rated power is equal to or greater than the specified value. A search is performed from the information storage unit 241 (see FIG. 9).
　検索により該当する住居ＩＤが見つからなかった場合、管理サーバ２は、規定値を大きくする。該当する住居ＩＤが見つかるまで繰り返す。 If the corresponding residence ID is not found by the search, the management server 2 increases the specified value. Repeat until the appropriate residence ID is found.
　その後、管理サーバ２は、該当した住居ＩＤについて、上記電力使用量情報と同じ年月の電力使用量情報を参照する。その後、管理サーバ２は、該当した住居ＩＤの住居８を比較対象住居に選定し、自住居の電力使用量情報（総電力使用量情報、年月情報）と比較対象住居の電力使用量情報とをＷｅｂコンテンツへ反映する。 Thereafter, the management server 2 refers to the power usage information of the same year as the power usage information for the corresponding residence ID. Thereafter, the management server 2 selects the residence 8 having the corresponding residence ID as the comparison target residence, and uses the power usage information (total power usage information, year / month information) of the own residence and the power usage information of the comparison target residence. Is reflected in the Web content.
　次に、本実施形態に係る電力管理システムの使用例について図１３を用いて説明する。図１３に示すように、実施形態２と同様、自住居８１に対して４戸の他住居８２～８５が存在する場合について説明する。ただし、自住居８１および他住居８２，８３，８５の機器構成は実施形態２の場合と同じであるが、他住居８４の機器構成は実施形態２の場合とは異なる。他住居８４には、機器種別「Ａ」である第１の電気機器７１が２台、機器種別「Ｂ」である第２の電気機器７２が１台、機器種別「Ｃ」である第３の電気機器７３が３台、機器種別「Ｄ」である第４の電気機器７４が１台、機器種別「Ｅ」である第５の電気機器７５が１台の計８台の電気機器７が設置されている。なお、本実施形態における第１～６の電気機器７１～７６の基準定格電力は、実施形態２の場合と同じである（図１２参照）。 Next, a usage example of the power management system according to the present embodiment will be described with reference to FIG. As shown in FIG. 13, a case where there are four other residences 82 to 85 for the own residence 81 as in the second embodiment will be described. However, the device configuration of the own residence 81 and the other residences 82, 83, and 85 is the same as that in the second embodiment, but the device configuration of the other residence 84 is different from that in the second embodiment. In the other residence 84, there are two first electric devices 71 having the device type “A”, one second electric device 72 having the device type “B”, and a third electric device 71 having the device type “C”. A total of eight electric devices 7 are installed, including three electric devices 73, one fourth electric device 74 having a device type “D”, and one fifth electric device 75 having a device type “E”. Has been. Note that the reference rated power of the first to sixth electric devices 71 to 76 in the present embodiment is the same as that in the second embodiment (see FIG. 12).
　本実施形態において、各住居８１－８５の機器構成は下表４のようになる。 In this embodiment, the equipment configuration of each of the residences 81-85 is as shown in Table 4 below.
Figure JPOXMLDOC01-appb-T000004
Figure JPOXMLDOC01-appb-T000004
　例えば、規定値の初期値が３００Ｗである場合、最初の検索処理において基準定格電力が規定範囲内であるのは機器種別「Ａ」，「Ｂ」，「Ｃ」，「Ｄ」の４つである。 For example, when the initial value of the specified value is 300 W, the device type “A”, “B”, “C”, “D” has the reference rated power within the specified range in the first search process. is there.
　表４から明らかなように、第１の住居８１の機器構成（基準構成）は、機器種別「Ａ」，「Ｂ」，「Ｃ」，「Ｄ」にそれぞれ対応する電気機器７の数において、いずれの住居８の機器構成とも一致しない。 As is apparent from Table 4, the device configuration (reference configuration) of the first residence 81 is the number of electrical devices 7 corresponding to the device types “A”, “B”, “C”, and “D”, respectively. It does not correspond to the equipment configuration of any residence 8.
　そのため、検索部２２１２は、規定値を所定値だけ増加させて、再度、検索処理（２回目の検索処理）を行う。本実施形態では、所定値は、２００Ｗである。よって、２回目の検索処理において、規定値は５００Ｗになる。２回目の検索処理において基準定格電力が規定値（５００Ｗ）以上であるのは機器種別「Ａ」，「Ｂ」，「Ｃ」の３つである。 Therefore, the search unit 2212 increases the specified value by a predetermined value and performs the search process (second search process) again. In the present embodiment, the predetermined value is 200W. Therefore, in the second search process, the specified value is 500W. In the second search process, there are three device types “A”, “B”, and “C” whose reference rated power is greater than or equal to the specified value (500 W).
　表４から明らかなように、第１の住居８１の機器構成（基準構成）は、機器種別「Ａ」，「Ｂ」，「Ｃ」にそれぞれ対応する電気機器７の数において、いずれの住居８の機器構成とも一致しない。 As apparent from Table 4, the device configuration (reference configuration) of the first residence 81 is any residence 8 in the number of electrical devices 7 corresponding to the device types “A”, “B”, and “C”, respectively. It does not match the equipment configuration.
　そのため、検索部２２１２は、規定値を所定値だけ増加させて、再度、検索処理（３回目の検索処理）を行う。よって、３回目の検索処理において、規定値は７００Ｗになる。３回目の検索処理において基準定格電力が規定値（７００Ｗ）以上であるのは機器種別「Ａ」，「Ｂ」，「Ｃ」の３つである。よって、結果は変わらない。 Therefore, the search unit 2212 increases the specified value by a predetermined value and performs the search process (third search process) again. Therefore, in the third search process, the specified value is 700 W. In the third search process, there are three device types “A”, “B”, and “C” whose reference rated power is greater than or equal to the specified value (700 W). Therefore, the result does not change.
　そのため、検索部２２１２は、規定値をさらに所定値だけ増加させて、再度、検索処理（４回目の検索処理）を行う。よって、４回目の検索処理において、規定値は９００Ｗになる。４回目の検索処理において基準定格電力が規定値（９００Ｗ）以上であるのは機器種別「Ａ」，「Ｂ」の２つである。 Therefore, the search unit 2212 further increases the specified value by a predetermined value, and performs the search process (fourth search process) again. Therefore, the specified value is 900 W in the fourth search process. In the fourth search process, there are two device types “A” and “B” whose reference rated power is the specified value (900 W) or more.
　表４から明らかなように、第１の住居８１の機器構成（基準構成）は、機器種別「Ａ」，「Ｂ」にそれぞれ対応する電気機器７の数において、第４および第５の住居８４，８５の機器構成と一致する。よって、検索部２２１２は、第４の住居８４に対応する機器構成情報および第５の住居８５に対応する機器構成情報を機器構成情報記憶部２４１から発見して、取得する。 As is apparent from Table 4, the device configuration (reference configuration) of the first residence 81 is the fourth and fifth residences 84 in the number of electrical devices 7 corresponding to the device types “A” and “B”, respectively. , 85. Therefore, the search unit 2212 finds and acquires the device configuration information corresponding to the fourth residence 84 and the device configuration information corresponding to the fifth residence 85 from the device configuration information storage unit 241.
　住居識別子取得部２２１３は、検索処理において発見された機器構成情報に含まれる住居ＩＤ「０ｘ０００４」，「０ｘ０００５」を取得する。そして、住居識別子取得部２２１３は、基準構成選択部２２１１に与えられた住居ＩＤ「０ｘ０００１」に、取得した住居ＩＤ「０ｘ０００４」，「０ｘ０００５」を比較対象住居として関連付ける。 The residence identifier acquisition unit 2213 acquires the residence IDs “0x0004” and “0x0005” included in the device configuration information discovered in the search process. Then, the residence identifier acquisition unit 2213 associates the acquired residence IDs “0x0004” and “0x0005” with the residence ID “0x0001” given to the reference configuration selection unit 2211 as a comparison target residence.
　このように、規定値の初期値が３００Ｗである場合、第１～４の電気機器７１～７４が比較対象となる（図１２参照）。この場合、他住居８２～８５に機器構成が同じ住居は存在しないため、管理サーバ２は規定値を５００Ｗに変更する。この場合、第１～３の電気機器７１～７３が比較対象となる。しかしながら、この場合も他住居８２～８５に機器構成が同じ住居は存在しない。規定値を７００Ｗに変更した場合は規定値が５００Ｗである場合と条件が変わらないため、管理サーバ２は、規定値を９００Ｗに変更する。この場合、第１，２の電気機器７１，７２が比較対象となる。他住居８４，８５が自住居８１と同一の機器構成であるため、管理サーバ２は、他住居８４，８５を比較対象住居に選定する。 As described above, when the initial value of the specified value is 300 W, the first to fourth electric devices 71 to 74 are to be compared (see FIG. 12). In this case, since there is no residence having the same device configuration in the other residences 82 to 85, the management server 2 changes the specified value to 500W. In this case, the first to third electric devices 71 to 73 are to be compared. However, even in this case, there is no residence having the same device configuration in the other residences 82 to 85. When the specified value is changed to 700 W, the condition does not change from the case where the specified value is 500 W. Therefore, the management server 2 changes the specified value to 900 W. In this case, the first and second electric devices 71 and 72 are to be compared. Since the other residences 84 and 85 have the same device configuration as that of the own residence 81, the management server 2 selects the other residences 84 and 85 as comparison target residences.
　以上述べたように、本実施形態の電力管理システムでは、検索部２２１２は、検索処理において基準構成と同一の機器構成を含む機器構成情報を機器構成情報記憶部２４１から発見できなければ、規定値を所定値だけ増加させて、再度、検索処理を行うように構成される。 As described above, in the power management system of the present embodiment, the search unit 2212 does not find the device configuration information including the same device configuration as the reference configuration in the search process from the device configuration information storage unit 241. Is increased by a predetermined value, and the search process is performed again.
　以上、本実施形態の電力管理システムによれば、比較対象住居を選定することができなかった場合に、規定値をこれまでよりも大きくし、基準定格電力が規定値以上である電気機器７の数を減らしてから、再度、比較対象住居を選定している。これにより、他の住居８との機器構成の類似具合と総電力使用量に占める各電気機器７の電力使用量の割合とを考慮しながら、最適な比較対象住居を選定することができる。 As described above, according to the power management system of the present embodiment, when the comparison target residence cannot be selected, the specified value is made larger than before, and the electric power 7 whose reference rated power is equal to or higher than the specified value. After reducing the number, the house for comparison is selected again. Accordingly, it is possible to select an optimal comparison target residence while taking into account the degree of similarity of the device configuration with the other residences 8 and the ratio of the power usage of each electrical device 7 to the total power usage.
　（実施形態４）
　実施形態４に係る電力管理システムは、自住居および比較対象住居の機器種別ごとの電力使用量情報を表示する点で、実施形態３に係る電力管理システムと相違する。すなわち、本実施形態において、電力使用量情報は、電気機器７の機器種別ごとの電力使用量の情報である。以下、本実施形態の電力管理システムについて図１，９および図１４－１７を用いて説明する。なお、実施形態３の電力管理システムと同様の構成要素については、同一の符号を付して説明を省略する。 (Embodiment 4)
The power management system according to the fourth embodiment is different from the power management system according to the third embodiment in that the power usage information for each device type of the own residence and the comparison target residence is displayed. That is, in the present embodiment, the power usage information is information on the power usage for each device type of the electrical device 7. Hereinafter, the power management system of this embodiment will be described with reference to FIGS. 1 and 9 and FIGS. 14-17. In addition, about the component similar to the power management system of Embodiment 3, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態では、図１４に示すように、各電気機器７（図１参照）が機器種別単位で分電盤５（図１参照）の各ブレーカ系統に接続されている。ブレーカ系統と機器種別との対応関係は、コントローラ３（図１参照）および管理サーバ２（図９参照）で共有されている。すなわち、コントローラ３および管理サーバ２は、ブレーカ系統と機器種別との対応関係を記憶する。 In this embodiment, as shown in FIG. 14, each electric device 7 (see FIG. 1) is connected to each breaker system of the distribution board 5 (see FIG. 1) in units of device type. The correspondence between the breaker system and the device type is shared by the controller 3 (see FIG. 1) and the management server 2 (see FIG. 9). That is, the controller 3 and the management server 2 store the correspondence relationship between the breaker system and the device type.
　本実施形態の電力情報取得部３２（図１参照）は、ブレーカ系統別に１ヶ月分の電力使用量の情報を分電盤５から収集する。分電盤５から収集した情報は、図１５に示すように、ブレーカ系統情報と、系統別電力使用量情報とで構成されている。上記より、本実施形態の電力情報取得部３２は、機器種別ごとの１ヶ月分の電力使用量の情報を取得することができる。電力情報取得部３２は、分電盤５から収集した情報を用いて電力使用量情報を作成する。本実施形態の電力使用量情報は、図１６に示すように、住居ＩＤと、年月情報と、総電力使用量情報と、ブレーカ系統情報と、系統別電力使用量情報とで構成されている。電力使用量情報は、図１７に示すように、電力使用量情報記憶部２４２に記憶される。 The power information acquisition unit 32 (see FIG. 1) of the present embodiment collects information on the power consumption for one month from the distribution board 5 for each breaker system. As shown in FIG. 15, the information collected from the distribution board 5 includes breaker system information and system power usage information. From the above, the power information acquisition unit 32 of the present embodiment can acquire information on the amount of power used for one month for each device type. The power information acquisition unit 32 creates power usage information using information collected from the distribution board 5. As shown in FIG. 16, the power usage information of the present embodiment includes a residence ID, year / month information, total power usage information, breaker system information, and system-specific power usage information. . The power usage information is stored in the power usage information storage unit 242 as shown in FIG.
　次に、本実施形態に係る電力管理システムの動作について説明する。まず、分電盤５は、コントローラ３に各ブレーカ系統の電力使用量の情報を通知する。その後、コントローラ３は、電力使用量情報を管理サーバ２に送信する。管理サーバ２は、上記電力使用量情報を電力使用量情報記憶部２４２に書き込む。その後、実施形態３と同様の手順によって、管理サーバ２は比較対象住居を選定する。その後、管理サーバ２は、自住居および比較対象住居の電力使用量情報のうち、基準定格電力が規定値以上である電気機器７に該当するブレーカ系統の電力使用量の情報を読み出す。管理サーバ２は、自住居および比較対象住居における上記ブレーカ系統の電力使用量の情報をＷｅｂコンテンツへ反映する。 Next, the operation of the power management system according to this embodiment will be described. First, the distribution board 5 notifies the controller 3 of the power usage information of each breaker system. Thereafter, the controller 3 transmits power usage information to the management server 2. The management server 2 writes the power usage information in the power usage information storage unit 242. Thereafter, the management server 2 selects a comparison target residence by the same procedure as in the third embodiment.
