The controller (12) comprises a comparison unit (125), a communication unit (126) and a setting unit (127). The comparison unit (125) determines whether the difference between a number of occurrences of operating states on a previous day and a number of occurrences of operating states on the day before the previous day is equal to or greater than a predetermined number of occurrences. The communication unit (126) transmits, to a communication apparatus (16), notification information based on the comparison result if the difference in the number of occurrences of operating states is equal to or greater than the predetermined number of occurrences. Thereafter, the setting unit (127) changes the threshold value on the basis of a threshold value setting request received by the communication unit (126) from the communication apparatus (16).

　従来、宅内の電気機器の電力消費量と閾値とを比較して、電力消費量が閾値以上である場合に電気機器のオン、オフを検出するシステムがある。このシステムでは、電力消費量が閾値以上である場合、電力消費量の立ち上がり幅が所定値以上になれば、電気機器のオンと判定する。また、電力消費量の立ち下がり幅が所定値以上になれば、電気機器のオフと判定する。そして、電気機器のオン時、オフ時には生活者が在宅していると判定される。このシステムでは、電力消費量と比較される閾値は、電気機器の電力消費量の推移を基に設定されている（例えば、文献１「日本国特許公開２０１２－６８７７４号公報」参照）。 Conventionally, there is a system that detects the on / off state of an electrical device when the power consumption is equal to or greater than the threshold value by comparing the power consumption amount of the electrical device in the home. In this system, when the power consumption is equal to or greater than the threshold value, it is determined that the electrical device is on if the rising width of the power consumption is equal to or greater than a predetermined value. Moreover, if the falling width of the power consumption is equal to or greater than a predetermined value, it is determined that the electrical device is off. It is determined that the consumer is at home when the electrical device is on and off. In this system, the threshold value to be compared with the power consumption amount is set based on the transition of the power consumption amount of the electric equipment (for example, see Document 1 “Japanese Patent Publication No. 2012-68774”).
　電気機器の動作モードが変更された場合、あるいは電気機器が交換された場合、あるいは電気機器が劣化した場合等に、電気機器の電力消費量が変化する可能性がある。例えば、電気機器がテレビであった場合、映像モードの設定、音量モードの設定などによって電力消費量が変化する。また、テレビを交換した場合にも、電力消費量が変化する。そこで、電気機器の動作モードが変更された場合、あるいは電気機器が交換された場合、あるいは電気機器が劣化した場合等には、上述の比較処理に用いられる閾値を変更する必要がある。 ・ Electric device power consumption may change when the operation mode of the electric device is changed, when the electric device is replaced, or when the electric device deteriorates. For example, when the electrical device is a television, the power consumption changes depending on the video mode setting, the volume mode setting, and the like. Also, the power consumption changes when the television is replaced. Therefore, when the operation mode of the electric device is changed, when the electric device is replaced, or when the electric device is deteriorated, it is necessary to change the threshold value used in the above comparison process.
　しかしながら、上述の文献１では、電気機器の電力消費量の推移を基に閾値が設定されるため、新たな電力消費量の推移データを蓄積する処理、蓄積したデータを分析する処理等が必要であり、閾値が変更されるまでに多くの処理を要するという問題がある。 However, in the above-mentioned document 1, since a threshold is set based on the transition of the power consumption of the electric device, a process for accumulating new transition data of the power consumption, a process for analyzing the accumulated data, and the like are necessary. There is a problem that many processes are required until the threshold value is changed.
　本発明は、上記事由に鑑みてなされており、その目的は、電気機器の動作モード変更、交換、劣化等があった場合に、電気機器の状態判定に用いる閾値を変更するために必要な処理を削減できるコントローラ、およびそれを用いた機器状態判定システムを提供することにある。 The present invention has been made in view of the above reasons, and its purpose is to perform processing necessary for changing a threshold value used for determining the state of an electric device when there is a change, replacement, deterioration, or the like of the operation mode of the electric device. It is an object of the present invention to provide a controller capable of reducing the amount of noise and a device state determination system using the controller.
　本発明の一態様に係るコントローラは、所定エリアで使用されている電気機器の電力消費量のデータを取得する電力情報取得部と、前記電力消費量と閾値とを比較して、前記電力消費量が前記閾値以上となる場合に前記電気機器が動作している稼働状態であると判定する判定部と、第１の日の所定時間帯における前記稼働状態の発生パターンである第１の発生パターン、および少なくとも前記第１の日前の１または複数の第２の日における前記判定部の判定結果に基づいた前記所定時間帯における前記稼働状態の発生パターンである第２の発生パターンを記憶する記憶部と、前記第１の発生パターンと前記第２の発生パターンとを比較して、前記第１の発生パターンと前記第２の発生パターンとの間に差異があるか否かを判定する比較部と、前記第１の発生パターンと前記第２の発生パターンとの間に差異がある場合に前記比較部の比較結果に基づく通知情報を通信装置へ送信する通信部と、前記閾値を設定する閾値設定部とを備え、前記通信部が前記通知情報を前記通信装置へ送信した後、前記閾値設定部は、前記通信部が前記通信装置から受信した前記閾値に関する情報に基づいて前記閾値を変更することを特徴とする。 The controller according to one aspect of the present invention compares the power consumption and a threshold with a power information acquisition unit that acquires power consumption data of an electrical device used in a predetermined area, and the power consumption A determination unit that determines that the electrical device is in an operating state in which the electrical device is operating when the threshold is equal to or greater than the threshold, and a first generation pattern that is the generation pattern of the operating state in a predetermined time zone on the first day, And a storage unit that stores a second generation pattern that is a generation pattern of the operating state in the predetermined time period based on a determination result of the determination unit on one or more second days before the first day.

　本発明の一態様に係る機器状態判定システムは、上述したコントローラと、前記電力消費量のデータを送信する前記通信装置とを備えることを特徴とする。 A device state determination system according to an aspect of the present invention includes the above-described controller and the communication device that transmits the power consumption data.
　上述したコントローラ、機器状態判定システムは、電気機器の動作モード変更、交換、劣化等があった場合に、新たな電力消費量の推移データを蓄積する処理、蓄積したデータを分析する処理等の従来は必要であった処理が不要となる。したがって、上述したコントローラ、機器状態判定システムは、電気機器の動作モード変更、交換、劣化等があった場合に、電気機器の状態判定に用いる閾値を変更するために必要な処理を削減できるという効果がある。 The above-described controller and device status determination system is a conventional method for accumulating new power consumption transition data, analyzing accumulated data, etc. when there is a change, replacement, or deterioration of the operation mode of an electrical device. The processing that was necessary becomes unnecessary. Therefore, the controller and the device state determination system described above can reduce the processing required for changing the threshold value used for the state determination of the electrical device when the operation mode of the electrical device is changed, replaced, deteriorated, or the like. There is.

　以下、本発明に係る実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　（実施形態）
　図１は、本実施形態のコントローラ１２を用いた機器状態判定システムの構成を示す。この機器状態判定システムは、分電盤１１、コントローラ１２、通信装置１６を主構成として備える。 (Embodiment)
FIG. 1 shows a configuration of a device state determination system using the controller 12 of the present embodiment. This device state determination system includes a distribution board 11, a controller 12, and a communication device 16 as main components.
　分電盤１１は、集合住宅の各住戸、戸建住宅、工場、事務所等の需要家（ｆａｃｉｌｉｔｙ）内（所定エリア内）に引き込まれたＡＣ１００／２００Ｖの幹線電路２１が接続され、幹線電路２１を介して、電力会社の電力系統から商用電力が供給される。分電盤１１は、分岐部１１１、計測部１１２を備える。分岐部１１１は、複数の分岐ブレーカから構成されており、幹線電路２１は、分岐部１１１を介して、需要家内に敷設した複数の分岐電路２２に分岐する。計測部１１２は、分岐電路２２のそれぞれで消費される電力（分岐電力）を計測する機能と、コントローラ１２との間で通信（有線または無線）を行う機能とを有する。この計測部１１２は、分岐電路２２のそれぞれの電流を測定するロゴスキーコイルまたは変流器を用いて構成される。また、計測部１１２は、分電盤１１の外部に設けられてもよい。そして、分岐電路２２のそれぞれは、空調装置、照明装置、テレビ等の電気機器１３が１つ以上接続され、分岐電路２２はこれらの電気機器１３へ動作電力を供給する。なお、需要家とは、電力を使用する人が居住または勤務または在室する建屋であり、集合住宅の各住戸、戸建住宅、工場、事務所等である。また、幹線電路２１には、太陽光発電装置、燃料電池、風力発電装置等の分散電源から発電電力が供給されてもよい。 The distribution board 11 is connected to an AC 100 / 200V main line 21 drawn into a facility (in a predetermined area) of each apartment, detached house, factory, office, etc. The commercial power is supplied from the power system of the power company through the power supply 21. The distribution board 11 includes a branching unit 111 and a measuring unit 112. The branch part 111 is composed of a plurality of branch breakers, and the main line 21 branches to a plurality of branch lines 22 laid in the customer via the branch part 111. The measuring unit 112 has a function of measuring the power (branch power) consumed in each branch electric circuit 22 and a function of performing communication (wired or wireless) with the controller 12. The measuring unit 112 is configured using a Rogowski coil or a current transformer that measures each current of the branch electric circuit 22. Further, the measuring unit 112 may be provided outside the distribution board 11. Each branch circuit 22 is connected to one or more electrical devices 13 such as an air conditioner, a lighting device, and a television, and the branch circuit 22 supplies operating power to these electrical devices 13. A consumer is a building where a person who uses electric power lives, works, or occupies a room, such as a dwelling unit, a detached house, a factory, an office, or the like of an apartment house. Further, the main line 21 may be supplied with generated power from a distributed power source such as a solar power generation device, a fuel cell, or a wind power generation device.
　コントローラ１２は、取得部１２１（電力情報取得部）と、第１の記憶部１２２と、判定部１２３と、第２の記憶部１２４と、比較部１２５と、通信部１２６と、設定部１２７（閾値設定部）とを備える。 The controller 12 includes an acquisition unit 121 (power information acquisition unit), a first storage unit 122, a determination unit 123, a second storage unit 124, a comparison unit 125, a communication unit 126, and a setting unit 127 ( Threshold setting unit).
　取得部１２１は、計測部１１２との間で通信を行い、複数の分岐電路２２のそれぞれの分岐電力のデータを、計測部１１２から定期的に取得する。取得部１２１が取得した複数の分岐電路２２のそれぞれの分岐電力のデータは、第１の記憶部１２２に格納される。第１の記憶部１２２は、少なくとも今日、前日、前々日の分岐電力のデータを格納しており、古いデータから順次削除される。この分岐電力のデータは、分岐電路２２毎の電気機器１３の電力消費量のデータである。 The acquisition unit 121 communicates with the measurement unit 112 and periodically acquires data of branch power of each of the plurality of branch electric circuits 22 from the measurement unit 112. The branch power data of each of the plurality of branch electric circuits 22 acquired by the acquisition unit 121 is stored in the first storage unit 122. The first storage unit 122 stores the branch power data of at least today, the previous day, and the day before, and is sequentially deleted from the old data. The branch power data is power consumption data of the electrical device 13 for each branch circuit 22.
　判定部１２３は、第１の記憶部１２２に格納した分岐電力のデータを用いて、監視対象となる電気機器１３の所定時間帯における状態を判定する。監視対象となる電気機器１３は、需要家内の人の活動と電力消費量との相関が高い機器である。 The determination unit 123 determines the state of the electrical device 13 to be monitored in a predetermined time zone using the branch power data stored in the first storage unit 122. The electrical device 13 to be monitored is a device having a high correlation between the activity of the person in the consumer and the power consumption.
　以降、監視対象の電気機器１３を対象機器１３ａと称す。対象機器１３ａが接続している分岐電路２２を監視電路２２ａと称し、いずれの分岐電路２２が監視電路２２ａであるかは判定部１２３に設定されている。また、監視電路２２ａの分岐電力を監視電力と称す。また、対象機器１３ａが監視される所定時間帯は、対象機器１３ａの使用時間帯に対応するように判定部１２３に設定されており、以降では監視時間帯Ｔ１と称す。そして、判定部１２３は、監視電路２２ａの情報、監視時間帯Ｔ１の情報を書き換え可能に保持している。 Hereinafter, the electrical device 13 to be monitored is referred to as a target device 13a. The branch electric circuit 22 to which the target device 13a is connected is referred to as a monitoring electric circuit 22a, and which branch electric circuit 22 is the monitoring electric circuit 22a is set in the determination unit 123. Further, the branch power of the monitoring circuit 22a is referred to as monitoring power. Further, the predetermined time zone in which the target device 13a is monitored is set in the determination unit 123 so as to correspond to the usage time zone of the target device 13a, and is hereinafter referred to as a monitoring time zone T1. And the determination part 123 hold | maintains the information of the monitoring electric circuit 22a and the information of the monitoring time slot | zone T1 so that rewriting is possible.
　具体的に判定部１２３は、図２に示すように、監視時間帯Ｔ１（図２では、８時～２２時）における監視電力Ｘ１と閾値Ｋ１とを比較する。そして、判定部１２３は、監視電力Ｘ１が閾値Ｋ１以上となる場合に、対象機器１３ａが動作している状態（稼働状態）であると判定し、監視電力Ｘ１が閾値Ｋ１未満となる場合に、対象機器１３ａが停止している状態（停止状態）であると判定する。閾値Ｋ１は、監視電路２２ａの待機電力に基づいて設定され、例えば待機電力に一定値を加算した値に設定される。なお、対象機器１３ａの停止状態には、対象機器１３ａの電力消費量がゼロである状態だけでなく、対象機器１３ａがスリープ状態になって電力消費量が微少である状態も含まれる。 Specifically, as shown in FIG. 2, the determination unit 123 compares the monitoring power X1 and the threshold value K1 in the monitoring time period T1 (from 8:00 to 22:00 in FIG. 2). Then, the determination unit 123 determines that the target device 13a is operating (operating state) when the monitored power X1 is equal to or greater than the threshold value K1, and when the monitored power X1 is less than the threshold value K1, It is determined that the target device 13a is in a stopped state (stopped state). The threshold value K1 is set based on the standby power of the monitoring electric circuit 22a, and is set to a value obtained by adding a certain value to the standby power, for example. The stopped state of the target device 13a includes not only a state where the power consumption of the target device 13a is zero but also a state where the target device 13a is in the sleep state and the power consumption is very small.
　判定部１２３は、監視時間帯Ｔ１における対象機器１３ａの状態（稼働状態、停止状態）を毎日判定する。判定部１２３は、日毎の判定結果に基づいて、対象機器１３ａが停止状態から稼働状態に切り替わった回数（稼働回数）を日毎に検出する。この監視時間帯Ｔ１における対象機器１３ａの稼働回数のデータは、第２の記憶部１２４に格納される。すなわち、第２の記憶部１２４には、毎日の稼働回数のデータ（稼働回数の履歴データ）が監視電路２２ａに対応付けて格納されている。また、判定部１２３は、対象機器１３ａが稼働状態から停止状態に切り替わった回数を日毎に検出してもよい。 The determination unit 123 determines the state (operating state, stopped state) of the target device 13a in the monitoring time period T1 every day. The determination unit 123 detects, for each day, the number of times (the number of operations) that the target device 13a has been switched from the stopped state to the operating state based on the determination result for each day. Data on the number of operations of the target device 13a in the monitoring time period T1 is stored in the second storage unit 124. That is, in the second storage unit 124, data on the number of daily operations (operation history data) is stored in association with the monitoring electric circuit 22a. Moreover, the determination part 123 may detect the frequency | count that the object apparatus 13a switched from the operation state to the stop state for every day.
　ここでは、最新の稼働回数が、前日（第１の日）の監視時間帯Ｔ１における稼働状態の発生パターン（第１の発生パターン）である。また、２番目に新しい稼働回数が、前々日（第２の日）の監視時間帯Ｔ１における稼働状態の発生パターン（第２の発生パターン）である。すなわち、稼働状態の発生パターンは、稼働状態の発生回数であることが好ましい。 Here, the latest operation count is an operation state generation pattern (first generation pattern) in the monitoring time period T1 of the previous day (first day). In addition, the second most recent operation count is an operation state generation pattern (second generation pattern) in the monitoring time period T1 of the previous day (second day). That is, the operation state occurrence pattern is preferably the number of occurrences of the operation state.
　比較部１２５は、前日の稼働回数と前々日の稼働回数とを比較して、この稼働回数の差が所定回数以上であるか否かを判定する。すなわち、比較部１２５は、稼働回数の差が所定回数以上である場合に、前日の稼働回数と前々日の稼働回数との間に差異があると判定する。比較部１２５は、稼働回数の差が所定回数未満である場合に、前日の稼働回数と前々日の稼働回数との間に差異がないと判定する。比較部１２５は、稼働回数の差が所定回数以上である場合、対象機器１３ａの動作モード変更、交換、劣化等によって、稼働状態の誤検出、検出漏れが発生しているとして、閾値Ｋ１を変更する必要があると認識する。 The comparison unit 125 compares the number of operations on the previous day with the number of operations on the previous day, and determines whether the difference in the number of operations is equal to or greater than a predetermined number. In other words, the comparison unit 125 determines that there is a difference between the number of operations on the previous day and the number of operations on the previous day when the difference in the number of operations is a predetermined number or more. When the difference in the number of operations is less than the predetermined number, the comparison unit 125 determines that there is no difference between the number of operations on the previous day and the number of operations on the previous day. When the difference in the number of operations is equal to or greater than the predetermined number, the comparison unit 125 changes the threshold value K1 on the assumption that an erroneous detection of the operation state or a detection failure has occurred due to an operation mode change, replacement, deterioration, or the like of the target device 13a. Recognize that it is necessary.
　通信部１２６は、ルータ１４を通してインターネット等の広域ネットワーク１５に接続している。そして、通信装置１６も広域ネットワーク１５に接続しており、通信部１２６は、通信装置１６との間で通信が可能になる。通信装置１６は、機器状態判定システムを利用するユーザが携行する携帯電話、情報端末や、需要家内に設置されたパーソナルコンピュータ、専用端末等である。 The communication unit 126 is connected to the wide area network 15 such as the Internet through the router 14. The communication device 16 is also connected to the wide area network 15, and the communication unit 126 can communicate with the communication device 16. The communication device 16 is a mobile phone carried by a user who uses the device state determination system, an information terminal, a personal computer installed in a consumer, a dedicated terminal, or the like.
　設定部１２７は、判定部１２３の判定処理に用いられる閾値Ｋ１を設定、変更する機能を有する。 The setting unit 127 has a function of setting and changing the threshold value K1 used for the determination process of the determination unit 123.
　以下、コントローラ１２における閾値Ｋ１の変更処理について、図３のフローチャートを用いて説明する。 Hereinafter, the process of changing the threshold value K1 in the controller 12 will be described with reference to the flowchart of FIG.
　閾値Ｋ１の変更処理が開始されると、判定部１２３は、監視電路２２ａの設定を確認し（Ｓ１）、監視時間帯Ｔ１の設定を確認する（Ｓ２）。次に判定部１２３は、前回の判定処理以降、監視電路２２ａの設定および監視時間帯Ｔ１の設定の少なくとも一方が変更されたか否かを判断する（Ｓ３）。そして、判定部１２３は、監視電路２２ａの設定および監視時間帯Ｔ１の設定の少なくとも一方に変更があった場合、閾値Ｋ１を予め決められた初期値に設定し直す（Ｓ４）。また、判定部１２３は、監視電路２２ａの設定および監視時間帯Ｔ１の設定に変更がない場合、前回の判定処理に用いた閾値Ｋ１を今回の判定処理にも用いる。 When the threshold K1 changing process is started, the determination unit 123 confirms the setting of the monitoring electric circuit 22a (S1) and confirms the setting of the monitoring time zone T1 (S2). Next, the determination unit 123 determines whether or not at least one of the setting of the monitoring electric circuit 22a and the setting of the monitoring time zone T1 has been changed since the previous determination processing (S3). Then, when there is a change in at least one of the setting of the monitoring electric circuit 22a and the setting of the monitoring time zone T1, the determination unit 123 resets the threshold value K1 to a predetermined initial value (S4). Further, when there is no change in the setting of the monitoring electric path 22a and the setting of the monitoring time zone T1, the determination unit 123 uses the threshold value K1 used in the previous determination process for the current determination process.
　次に、判定部１２３は、前日（最新）の監視時間帯Ｔ１における監視電力Ｘ１と閾値Ｋ１とを比較し、最新の監視時間帯Ｔ１における稼働回数Ｎ１を検出する（Ｓ５）。判定部１２３は、検出した稼働回数Ｎ１のデータを第２の記憶部１２４に格納する（Ｓ６）。この第２の記憶部１２４には、稼働回数の履歴データが格納されている。 Next, the determination unit 123 compares the monitoring power X1 in the monitoring time period T1 of the previous day (latest) with the threshold value K1, and detects the number of operations N1 in the latest monitoring time period T1 (S5). The determination unit 123 stores the data of the detected operation number N1 in the second storage unit 124 (S6). The second storage unit 124 stores history data of the number of operations.
　次に、比較部１２５は、第２の記憶部１２４を参照し、前日の稼働回数Ｎ１（稼働回数Ｎ１１とする）と前々日の稼働回数Ｎ１（稼働回数Ｎ１２とする）とを比較する。そして、比較部１２５は、稼働回数の差［Ｎ１１－Ｎ１２］が、－Ｙ１回＜［Ｎ１１－Ｎ１２］＜＋Ｙ１回であるか否かを判定する（Ｓ７）。比較部１２５は、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下または＋Ｙ１回以上である場合、対象機器１３ａの動作モード変更、交換、劣化等によって、稼働状態の誤検出、検出漏れが発生しているとして、閾値Ｋ１を変更する必要があると認識する。比較部１２５は、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回より多く、＋Ｙ１回より少ない場合、閾値Ｋ１の変更処理を終了する。上述のＹ１は、任意の整数であり、例えばＹ１＝１０回に設定される。なお、Ｙ１は１０回以外でもよく、その具体的な回数は限定されない。なお、比較部１２５は、前々日以前の複数の日の稼働回数の平均を導出して、この稼働回数の平均値を稼働回数Ｎ１２としてもよい。さらに、比較部１２５は、前日以前の複数の日の稼働回数の平均を導出して、この稼働回数の平均値を稼働回数Ｎ１２としてもよい。 Next, the comparison unit 125 refers to the second storage unit 124, and compares the operation count N1 of the previous day (referred to as the operation count N11) with the operation count N1 of the previous day (referred to as the operation count N12). Then, the comparison unit 125 determines whether or not the difference in the number of operations [N11−N12] is −Y1 times <[N11−N12] <+ Y1 times (S7). When the difference [N11−N12] in the number of operations is −Y1 times or less or + Y1 times or more, the comparison unit 125 may cause erroneous detection or omission of the operation state due to operation mode change, replacement, deterioration, or the like of the target device 13a. It is recognized that it is necessary to change the threshold value K1. When the difference [N11−N12] in the number of operations is larger than −Y1 times and smaller than + Y1 times, the comparing unit 125 ends the threshold value K1 changing process. Y1 described above is an arbitrary integer, and is set to Y1 = 10 times, for example. Y1 may be other than 10 times, and the specific number is not limited. Note that the comparison unit 125 may derive the average of the number of operations on a plurality of days before the previous day and use the average value of the numbers of operations as the number of operations N12. Furthermore, the comparison unit 125 may derive the average of the number of operations on a plurality of days before the previous day and set the average value of the numbers of operations as the number of operations N12.
　次に、通信部１２６は、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下または＋Ｙ１回以上である場合、閾値Ｋ１の変更の必要性を伝える通知情報を、通信装置１６へ送信する（Ｓ８）。通知情報は、例えば「稼働回数の差がＺ回となりましたので、閾値Ｋ１を変更する必要があります。」というメッセージ等を含む。 Next, when the difference [N11−N12] in the number of operations is −Y1 times or less or + Y1 times or more, the communication unit 126 transmits notification information indicating the necessity of changing the threshold value K1 to the communication device 16 ( S8). The notification information includes, for example, a message “The threshold K1 needs to be changed because the difference in the number of operations is Z times”.
　通信装置１６は、液晶画面等の表示画面を備えており、通知情報を受信した通信装置１６は、表示画面に通知情報を表示する。通信装置１６は、変更後の閾値Ｋ１の値を指示する手動設定要求、または閾値Ｋ１の自動設定を要求する自動設定要求を、ユーザの操作によってコントローラ１２へ送信する。なお、通信装置１６は、通知情報を受信した時点でこの通知情報を表示画面に自動表示する構成、受信した通知情報をユーザの操作によって表示画面に表示する構成のいずれでもよい。 The communication device 16 includes a display screen such as a liquid crystal screen, and the communication device 16 that has received the notification information displays the notification information on the display screen. The communication device 16 transmits a manual setting request for instructing the value of the changed threshold value K1 or an automatic setting request for requesting automatic setting of the threshold value K1 to the controller 12 by a user operation. The communication device 16 may be configured to automatically display the notification information on the display screen when the notification information is received, or to display the received notification information on the display screen by a user operation.
　そして、通信部１２６は、通知情報に対する通信装置１６からの返信（手動設定要求または自動設定要求）を受信し、設定部１２７は、通信装置１６からの返信が手動設定要求と自動設定要求とのいずれであるかを判定する（Ｓ９）。通信部１２６が手動設定要求を受信した場合、設定部１２７は、この手動設定要求を参照して、ユーザによって指示された値（ユーザ指示値）に閾値Ｋ１を変更する（Ｓ１０）。 The communication unit 126 receives a reply (manual setting request or automatic setting request) from the communication device 16 to the notification information, and the setting unit 127 determines that the reply from the communication device 16 is a manual setting request and an automatic setting request. It is determined which one (S9). When the communication unit 126 receives the manual setting request, the setting unit 127 refers to the manual setting request and changes the threshold value K1 to a value (user instruction value) instructed by the user (S10).
　例えば、対象機器１３ａの動作モードが変更された場合、あるいは対象機器１３ａが交換された場合、あるいは対象機器１３ａが劣化した場合等に、対象機器１３ａの稼働時の電力消費量が変化する可能性がある。例えば、対象機器１３ａがテレビであった場合、映像モードの設定、音量モードの設定などによって稼働時の電力消費量が変化する。また、テレビを交換した場合にも、稼働時の電力消費量が変化する。 For example, when the operation mode of the target device 13a is changed, when the target device 13a is replaced, or when the target device 13a is deteriorated, the power consumption during operation of the target device 13a may change. There is. For example, when the target device 13a is a television, the power consumption during operation varies depending on the video mode setting, the volume mode setting, and the like. Also, when the TV is replaced, the power consumption during operation changes.
　そこで、コントローラ１２は、対象機器１３ａの稼働状態の検出回数が大幅に変化した場合、ユーザに対して閾値Ｋ１の変更を促す。そして、対象機器１３ａの状況（動作モード変更、交換の有無、劣化の進行度合い）を把握しているユーザが、対象機器１３ａの稼働回数の検出精度を向上させることができる閾値Ｋ１を設定する。すなわち、コントローラ１２は、対象機器１３ａの動作モード変更、交換、劣化等があった場合に、新たな電力消費量の推移データを蓄積する処理、蓄積したデータを分析する処理等の従来は必要であった処理が不要となる。したがって、コントローラ１２は、対象機器１３ａの動作モード変更、交換、劣化等があった場合に、対象機器１３ａの状態判定に用いる閾値Ｋ１を変更するために必要な処理を削減できる。 Therefore, the controller 12 prompts the user to change the threshold value K1 when the number of detections of the operating state of the target device 13a has changed significantly. Then, a user who knows the status of the target device 13a (operation mode change, presence / absence of replacement, progress degree of deterioration) sets a threshold value K1 that can improve the detection accuracy of the number of operations of the target device 13a. That is, the controller 12 is conventionally required to store new power consumption transition data and analyze the accumulated data when the operation mode of the target device 13a is changed, exchanged, or deteriorated. The processing that was required becomes unnecessary. Therefore, the controller 12 can reduce processing necessary for changing the threshold value K1 used for determining the state of the target device 13a when the operation mode of the target device 13a is changed, replaced, deteriorated, or the like.
　また、判定部１２３が検出する稼働状態の発生パターンとしては、監視時間帯Ｔ１における稼働回数以外に、監視時間帯Ｔ１における稼働状態の発生時刻、稼働状態の累積時間長さ等であってもよい。この場合、比較部１２５は、監視時間帯Ｔ１における稼働状態の発生時刻、累積時間長さ等の類似度を算出することによって、前日の稼働状態の発生パターンと前々日の稼働状態の発生パターンとの差を導出する。 In addition to the number of operations in the monitoring time period T1, the operation state occurrence pattern detected by the determination unit 123 may include the operation time occurrence time in the monitoring time period T1, the accumulated time length of the operating state, and the like. . In this case, the comparison unit 125 calculates the similarity of the operation state occurrence time, the accumulated time length, and the like in the monitoring time period T1, so that the operation state generation pattern of the previous day and the operation state generation pattern of the previous day are calculated. The difference is derived.
　すなわち、上述のコントローラ１２は、取得部１２１（電力情報取得部）と、判定部１２３と、第２の記憶部１２４（記憶部）と、比較部１２５と、通信部１２６と、設定部１２７（閾値設定部）とを備える。取得部１２１は、需要家（所定エリア）で使用されている対象機器１３ａ（電気機器）の監視電力Ｘ１（電力消費量）のデータを取得する。判定部１２３は、監視電力Ｘ１と閾値Ｋ１とを比較して、監視電力Ｘ１が閾値Ｋ１以上となる場合に対象機器１３ａが動作している稼働状態であると判定する。第２の記憶部１２４は、稼働状態の発生パターンとして、第１の発生パターンおよび第２の発生パターンを記憶する。第１の発生パターンは、第１の日の所定時間帯における稼働状態の発生パターンである。第２の発生パターンは、少なくとも第１の日前の１または複数の第２の日における判定部１２３の判定結果に基づいた所定時間帯における稼働状態の発生パターンである。比較部１２５は、第１の発生パターンと第２の発生パターンとを比較して、第１の発生パターンと第２の発生パターンとの間に差異があるか否かを判定する。通信部１２６は、第１の発生パターンと第２の発生パターンとの間に差異がある場合に比較部１２５の比較結果に基づく通知情報を通信装置１６へ送信する。設定部１２７は、閾値Ｋ１を設定する。そして、通信部１２６が通知情報を通信装置１６へ送信した後、設定部１２７は、通信部１２６が通信装置１６から受信した閾値Ｋ１に関する情報に基づいて閾値Ｋ１を変更する。 That is, the controller 12 includes the acquisition unit 121 (power information acquisition unit), the determination unit 123, the second storage unit 124 (storage unit), the comparison unit 125, the communication unit 126, and the setting unit 127 ( Threshold setting unit). The acquisition unit 121 acquires monitoring power X1 (power consumption) data of the target device 13a (electrical device) used in a consumer (predetermined area). The determination unit 123 compares the monitoring power X1 with the threshold value K1, and determines that the target device 13a is operating when the monitoring power X1 is equal to or greater than the threshold value K1. The second storage unit 124 stores the first generation pattern and the second generation pattern as the operation state generation patterns. The first occurrence pattern is an operation state occurrence pattern in a predetermined time zone on the first day. The second occurrence pattern is an operation state occurrence pattern in a predetermined time period based on the determination result of the determination unit 123 on at least one or a plurality of second days before the first day. The comparison unit 125 compares the first generation pattern and the second generation pattern to determine whether there is a difference between the first generation pattern and the second generation pattern. The communication unit 126 transmits notification information based on the comparison result of the comparison unit 125 to the communication device 16 when there is a difference between the first generation pattern and the second generation pattern. The setting unit 127 sets a threshold value K1. Then, after the communication unit 126 transmits the notification information to the communication device 16, the setting unit 127 changes the threshold value K <b> 1 based on the information regarding the threshold value K <b> 1 received from the communication device 16 by the communication unit 126.
　また、上述の機器状態判定システムは、コントローラ１２と、電力消費量のデータを送信する通信装置１６とを備える。 Further, the above-described device state determination system includes a controller 12 and a communication device 16 that transmits power consumption data.
　また、通信部１２６が自動設定要求を受信した場合、設定部１２７は、稼働回数の差［Ｎ１１－Ｎ１２］に基づく自動設定値に閾値Ｋ１を変更する（Ｓ１１）。例えば、稼働回数の差［Ｎ１１－Ｎ１２］が＋Ｙ１回以上である場合、稼働状態の誤検出が多くなっているので、設定部１２７は、変更後の閾値Ｋ１を変更前の閾値Ｋ１×係数１．３とする。また、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下である場合、稼働状態の検出漏れが多くなっているので、設定部１２７は、変更後の閾値Ｋ１を変更前の閾値Ｋ１×係数０．７とする。さらに、設定部１２７は、閾値Ｋ１の変更頻度が少なくなるように学習しながら、変更前の閾値Ｋ１に乗じる係数を適宜変更することが好ましい。 When the communication unit 126 receives an automatic setting request, the setting unit 127 changes the threshold value K1 to an automatic setting value based on the difference in the number of operations [N11−N12] (S11). For example, when the difference in the number of operations [N11−N12] is equal to or greater than + Y1, the setting unit 127 sets the threshold value K1 after the change to the threshold value K1 before the change × the coefficient 1 .3. Further, when the difference in the number of operations [N11−N12] is equal to or less than −Y1, the setting unit 127 sets the threshold K1 after the change to the threshold K1 before the change × the coefficient. 0.7. Furthermore, it is preferable that the setting unit 127 appropriately changes a coefficient by which the threshold value K1 before the change is multiplied while learning so that the change frequency of the threshold value K1 decreases.
　また、稼働回数の差［Ｎ１１－Ｎ１２］が＋Ｙ１回以上である場合、［Ｎ１１－Ｎ１２］の絶対値が大きいほど、設定部１２７は、変更後の閾値Ｋ１の値を大きくすることが好ましい。また、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下である場合、［Ｎ１１－Ｎ１２］の絶対値が大きいほど、設定部１２７は、変更後の閾値Ｋ１の値を小さくすることが好ましい。 Also, when the difference [N11−N12] in the number of operations is equal to or greater than + Y1, it is preferable that the setting unit 127 increases the value of the changed threshold value K1 as the absolute value of [N11−N12] increases. In addition, when the difference [N11−N12] in the number of operations is −Y1 times or less, it is preferable that the setting unit 127 decreases the value of the changed threshold value K1 as the absolute value of [N11−N12] increases. .
　したがって、対象機器１３ａの状況を把握していないユーザは、対象機器１３ａの稼働回数の検出精度を向上させることができる閾値Ｋ１をコントローラ１２に自動設定させることができる。すなわち、通信部１２６が通知情報を通信装置１６へ送信した後に、通信部１２６が通信装置１６から受信した情報が閾値Ｋ１の自動変更を指示する情報である場合、設定部１２７は、第１の発生パターンと第２の発生パターンとの間に差異に応じて閾値Ｋ１を変更することが好ましい。 Therefore, a user who does not grasp the status of the target device 13a can automatically set the threshold value K1 that can improve the detection accuracy of the number of operations of the target device 13a in the controller 12. That is, after the communication unit 126 transmits notification information to the communication device 16, when the information received from the communication device 16 by the communication unit 126 is information that instructs automatic change of the threshold value K <b> 1, the setting unit 127 It is preferable to change the threshold value K1 according to the difference between the generation pattern and the second generation pattern.
　また、対象機器１３ａだけでなく、他の電気機器１３も同一の監視電路２２ａに接続される場合がある。この場合、監視電力Ｘ１は、対象機器１３ａの電力消費量と他の電気機器１３の電力消費量との和となるが、コントローラ１２は、閾値Ｋ１を適切に設定することによって、対象機器１３ａの稼働状態を検出することが可能となる。 Further, not only the target device 13a but also other electrical devices 13 may be connected to the same monitoring circuit 22a. In this case, the monitoring power X1 is the sum of the power consumption of the target device 13a and the power consumption of the other electrical devices 13, but the controller 12 sets the threshold value K1 appropriately so that the target device 13a It becomes possible to detect the operating state.
　また、コントローラ１２は、判定部１２３の判定結果に基づいて需要家内の人の活動に関する情報（活動情報）を生成する生成部１２８（情報生成部）を備えることが好ましい。例えば、判定部１２３がテレビ、照明装置、空調装置等の対象機器１３ａの稼働状態を検出する場合、生成部１２８は、対象機器１３ａの稼働状態の検出結果に基づいて需要家における人の活動の有無を推定する。そして、生成部１２８は、この推定結果を活動情報として通信装置１６へ送信する。通信装置１６は、受信した活動情報を表示画面に表示して、需要家における人の活動状況をユーザへ通知する。 Moreover, it is preferable that the controller 12 includes a generation unit 128 (information generation unit) that generates information (activity information) related to the activity of the person in the consumer based on the determination result of the determination unit 123. For example, when the determination unit 123 detects the operation state of the target device 13a such as a television, a lighting device, or an air conditioner, the generation unit 128 detects the activity of the person in the consumer based on the detection result of the operation state of the target device 13a. Presence or absence is estimated. And the production | generation part 128 transmits this estimation result to the communication apparatus 16 as activity information. The communication device 16 displays the received activity information on the display screen and notifies the user of the activity status of the person in the consumer.
　したがって、需要家内の高齢者や子供などの見守り支援、帰宅通知等を行う活動判定システムが構築可能となる。さらに、コントローラ１２は、上述のように閾値Ｋ１を変更するために必要な処理を削減できるので、見守り支援、帰宅通知等を行う活動判定システムとしての能力を向上させることができる。 Therefore, it is possible to build an activity determination system that provides support for watching elderly people and children in the consumer, notification of returning home, and the like. Furthermore, since the controller 12 can reduce the processing necessary for changing the threshold value K1 as described above, it is possible to improve the ability as an activity determination system that performs watching support, notification of returning home, and the like.
　また、対象機器１３ａとしては、需要家における人の活動を推定し易い電気機器１３が設定される。また、監視時間帯Ｔ１は、対象機器１３ａの使用時間帯に対応する時間帯に設定される。そこで、通信部１２６は、通知情報を通信装置１６へ送信する場合、監視電路２２ａの再設定、監視時間帯Ｔ１の再設定の少なくとも１つをユーザに促す情報を通信装置１６へ送信することが好ましい。この場合、通信装置１６は、手動設定要求または自動設定要求の送信時に、監視電路２２ａの再設定、監視時間帯Ｔ１の再設定の各指示も併せて送信する。コントローラ１２は、受信した各指示に応じて、監視電路２２ａの再設定、監視時間帯Ｔ１の再設定を行う。したがって、コントローラ１２は、より適切な監視電路２２ａ、監視時間帯Ｔ１を設定できるので、対象機器１３ａの稼働状態の検出精度を向上させることができる。なお、監視電路２２ａの再設定は、電力消費量の監視対象となる対象機器１３ａを再設定することに相当する。 In addition, as the target device 13a, an electric device 13 that easily estimates human activities in the consumer is set. The monitoring time zone T1 is set to a time zone corresponding to the usage time zone of the target device 13a. Therefore, when transmitting the notification information to the communication device 16, the communication unit 126 may transmit information prompting the user to at least one of resetting the monitoring electric path 22 a and resetting the monitoring time zone T <b> 1 to the communication device 16. preferable. In this case, when transmitting the manual setting request or the automatic setting request, the communication device 16 also transmits instructions for resetting the monitoring electric circuit 22a and resetting the monitoring time zone T1. The controller 12 resets the monitoring electric circuit 22a and resets the monitoring time zone T1 according to each received instruction. Therefore, since the controller 12 can set a more appropriate monitoring electric circuit 22a and monitoring time zone T1, it is possible to improve the detection accuracy of the operating state of the target device 13a. Note that the resetting of the monitoring electrical path 22a corresponds to resetting the target device 13a to be monitored for power consumption.
　また、本実施形態の変形例として、複数系統の分岐電路２２のそれぞれが監視電路２２ａとして設定される場合がある。この場合、コントローラ１２は、図４，図５のフローチャートにしたがって動作する。 Also, as a modification of the present embodiment, each of a plurality of branch electric circuits 22 may be set as a monitoring electric circuit 22a. In this case, the controller 12 operates according to the flowcharts of FIGS.
　まず、閾値Ｋ１の変更処理が開始されると、判定部１２３は、監視電路２２ａの設定を確認し（Ｓ１）、監視電路２２ａが単一系統、複数系統のいずれであるかを確認する（Ｓ２１）。監視電路２２ａが単一系統であるとは、１つの分岐電路２２が監視電路２２ａとして設定されている場合であり、監視電路２２ａが複数系統であるとは、複数の分岐電路２２のそれぞれが監視電路２２ａとして設定されている場合である。監視電路２２ａが単一系統であれば、コントローラ１２は上述のステップＳ２～Ｓ１１の各処理を実行する。 First, when the threshold value K1 changing process is started, the determination unit 123 confirms the setting of the monitoring electric circuit 22a (S1), and confirms whether the monitoring electric circuit 22a is a single system or a plurality of systems (S21). ). The monitoring electric circuit 22a is a single system when one branch electric circuit 22 is set as the monitoring electric circuit 22a, and the monitoring electric circuit 22a is a plurality of systems when each of the plural branch electric circuits 22 is monitored. This is a case where the electric path 22a is set. If the monitoring electric circuit 22a is a single system, the controller 12 executes the processes in steps S2 to S11 described above.
　また、監視電路２２ａが複数系統であれば、コントローラ１２はステップＳ２２～Ｓ３１の各処理を実行する（図５参照）。この場合、判定部１２３は、複数系統の監視電路２２ａのそれぞれの監視時間帯Ｔ１の設定を確認する（Ｓ２２）。次に判定部１２３は、前回の判定処理以降、監視電路２２ａの設定および監視時間帯Ｔ１の設定の少なくとも一方が変更されたか否かを判断する（Ｓ２３）。そして、判定部１２３は、監視電路２２ａの設定および監視時間帯Ｔ１の設定の少なくとも一方に変更があった場合、該当する監視電路２２ａの閾値Ｋ１を予め決められた初期値に設定し直す（Ｓ２４）。また、判定部１２３は、監視電路２２ａの設定および監視時間帯Ｔ１の設定に変更がない場合、前回の判定処理に用いた閾値Ｋ１を今回の判定処理にも用いる。 Further, if the monitoring electric circuit 22a is a plurality of systems, the controller 12 executes each process of steps S22 to S31 (see FIG. 5). In this case, the determination unit 123 confirms the setting of the monitoring time zone T1 of each of the plurality of monitoring electric circuits 22a (S22). Next, the determination unit 123 determines whether or not at least one of the setting of the monitoring electric circuit 22a and the setting of the monitoring time zone T1 has been changed since the previous determination processing (S23). When at least one of the setting of the monitoring electric circuit 22a and the setting of the monitoring time zone T1 is changed, the determination unit 123 resets the threshold value K1 of the corresponding monitoring electric circuit 22a to a predetermined initial value (S24). ). Further, when there is no change in the setting of the monitoring electric path 22a and the setting of the monitoring time zone T1, the determination unit 123 uses the threshold value K1 used in the previous determination process for the current determination process.
　次に、判定部１２３は、複数系統の監視電路２２ａのそれぞれにおいて、前日（最新）の監視時間帯Ｔ１における監視電力Ｘ１と閾値Ｋ１とを比較し、最新の監視時間帯Ｔ１における稼働回数Ｎ１を検出する（Ｓ２５）。判定部１２３は、監視電路２２ａ毎に検出した稼働回数Ｎ１のデータを、監視電路２２ａ毎に第２の記憶部１２４に格納する（Ｓ２６）。この第２の記憶部１２４には、稼働回数の履歴データが監視電路２２ａ毎に格納されている。 Next, the determination unit 123 compares the monitoring power X1 and the threshold value K1 in the monitoring time zone T1 of the previous day (latest) in each of the monitoring power lines 22a of the plurality of systems, and determines the operation frequency N1 in the latest monitoring time zone T1. Detect (S25). The determination unit 123 stores the data of the operation frequency N1 detected for each monitoring electric circuit 22a in the second storage unit 124 for each monitoring electric circuit 22a (S26). The second storage unit 124 stores history data of the number of operations for each monitoring electric circuit 22a.
　次に、比較部１２５は、複数系統の監視電路２２ａのそれぞれにおいて、第２の記憶部１２４を参照し、前日の稼働回数Ｎ１１と前々日の稼働回数Ｎ１２とを比較する。そして、比較部１２５は、稼働回数の差［Ｎ１１－Ｎ１２］が、－Ｙ１回＜［Ｎ１１－Ｎ１２］＜＋Ｙ１回であるか否かを、監視電路２２ａ毎に判定する（Ｓ２７）。比較部１２５は、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下または＋Ｙ１回以上である場合、該当する監視電路２２ａの閾値Ｋ１を変更する必要があると認識する。比較部１２５は、全ての監視電路２２ａにおいて、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回より多く、＋Ｙ１回より少ない場合、閾値Ｋ１の変更処理を終了する。 Next, the comparison unit 125 refers to the second storage unit 124 in each of the monitoring electric circuits 22a of the plurality of systems, and compares the operation number N11 of the previous day with the operation number N12 of the previous day. Then, the comparison unit 125 determines, for each monitoring electric circuit 22a, whether or not the difference [N11−N12] in the number of operations is −Y1 times <[N11−N12] <+ Y1 times (S27). When the difference [N11−N12] in the number of operations is −Y1 times or less or + Y1 times or more, the comparison unit 125 recognizes that the threshold K1 of the corresponding monitoring circuit 22a needs to be changed. When the difference [N11−N12] in the number of operations is greater than −Y1 times and less than + Y1 times in all the monitoring electric circuits 22a, the comparison unit 125 ends the threshold value K1 changing process.
　次に、通信部１２６は、稼働回数の差［Ｎ１１－Ｎ１２］が－Ｙ１回以下または＋Ｙ１回以上である場合、該当する監視電路２２ａの閾値Ｋ１の変更の必要性を伝える通知情報を、通信装置１６へ送信する（Ｓ２８）。通知情報は、例えば「稼働回数の差がＺ回となりましたので、ｍ番目の監視電路の閾値Ｋ１を変更する必要があります。」というメッセージ等を含む。 Next, when the difference [N11−N12] in the number of operations is −Y1 times or less or + Y1 times or more, the communication unit 126 transmits notification information that informs the necessity of changing the threshold value K1 of the corresponding monitoring circuit 22a to the communication unit 126. It transmits to the apparatus 16 (S28). The notification information includes, for example, a message such as “the difference in the number of operations is Z times, and the threshold value K1 of the m-th monitoring electric circuit needs to be changed”.
　通知情報を受信した通信装置１６は、表示画面に通知情報を表示する。通信装置１６は、変更後の閾値Ｋ１の値を指示する手動設定要求、または閾値Ｋ１の自動設定を要求する自動設定要求を、ユーザの操作によってコントローラ１２へ送信する。そして、通信部１２６は、通知情報に対する通信装置１６からの返信（手動設定要求または自動設定要求）を受信し、設定部１２７は、通信装置１６からの返信が手動設定要求と自動設定要求とのいずれであるかを判定する（Ｓ２９）。 The communication device 16 that has received the notification information displays the notification information on the display screen. The communication device 16 transmits a manual setting request for instructing the value of the changed threshold value K1 or an automatic setting request for requesting automatic setting of the threshold value K1 to the controller 12 by a user operation. The communication unit 126 receives a reply (manual setting request or automatic setting request) from the communication device 16 to the notification information, and the setting unit 127 determines that the reply from the communication device 16 is a manual setting request and an automatic setting request. It is determined which one (S29).
　通信部１２６が手動設定要求を受信した場合、設定部１２７は、この手動設定要求を参照して、該当する監視電路２２ａの閾値Ｋ１を、ユーザによって指示された値（ユーザ指示値）に変更する（Ｓ３０）。 When the communication unit 126 receives a manual setting request, the setting unit 127 refers to the manual setting request and changes the threshold value K1 of the corresponding monitoring circuit 22a to a value (user instruction value) specified by the user. (S30).
　また、通信部１２６が自動設定要求を受信した場合、設定部１２７は、稼働回数の差［Ｎ１１－Ｎ１２］に基づく自動設定値に、該当する監視電路２２ａの閾値Ｋ１を変更する（Ｓ３１）。 Further, when the communication unit 126 receives the automatic setting request, the setting unit 127 changes the threshold value K1 of the corresponding monitoring circuit 22a to the automatic setting value based on the difference [N11−N12] in the number of operations (S31).
　すなわち、複数系統の監視電路２２ａが設定されている場合でも、コントローラ１２は、監視電路２２ａ毎に閾値Ｋ１の変更の必要性を判断し、監視電路２２ａ毎に閾値Ｋ１を変更する。したがって、複数系統の監視電路２２ａが設定されている場合でも、監視電路２２ａ毎に適した閾値Ｋ１を設定できる。 That is, even when a plurality of monitoring electric circuits 22a are set, the controller 12 determines the necessity of changing the threshold value K1 for each monitoring electric circuit 22a, and changes the threshold value K1 for each monitoring electric circuit 22a. Therefore, even when a plurality of monitoring electric circuits 22a are set, it is possible to set a threshold value K1 suitable for each monitoring electric circuit 22a.
　また、コントローラ１２は、第１の記憶部１２２に格納された複数系統の分岐電路２２のそれぞれの分岐電力のデータを用いて、ＨＥＭＳ（Home Energy Management System）を構築することが好ましい。ＨＥＭＳにおいて、コントローラ１２は、第１の記憶部１２２に格納されている分岐電力のデータを適宜の提示装置に提示することによって、電力消費量を見える化する機能を有する。またＨＥＮＳにおいて、コントローラ１２は、第１の記憶部１２２に格納されている分岐電力のデータに基づいて、省電力化を目的とした電気機器１３の制御を行う機能を有する。 Further, it is preferable that the controller 12 constructs a HEMS (Home Energy Management System) using data of the branch power of each of the plurality of branch circuits 22 stored in the first storage unit 122. In HEMS, the controller 12 has a function of visualizing power consumption by presenting branch power data stored in the first storage unit 122 to an appropriate presentation device. In HENS, the controller 12 has a function of controlling the electrical device 13 for the purpose of power saving based on the branch power data stored in the first storage unit 122.
