In other words, the equipment management system 10 according to the present embodiment includes a control system 1 and a host system 2. The control system 1 is installed in, for example, a facility in which the electric power-related equipment 3 is installed, and the host system 2 is installed, for example, in a place away from this facility.

On the other hand, in a situation where the communication between the control system 1 and the host system 2 is cut off, the control system 1 controls the power-related equipment 3 based on the preliminary information corresponding to the prediction information. Therefore, even in a situation where the communication between the control system 1 and the host system 2 is cut off, the power-related equipment 3 can be efficiently installed. As a result, it is not easily affected by the communication status when controlling the power-related equipment 3.

That is, a plurality of control systems 1 can communicate with one host system 2. Each of the plurality of control systems 1 controls the power-related facility 3 as a control target.

　（２．２）各部の構成
　次に、本実施形態に係る制御システム１、上位システム２及び学習システム５の各々の構成について、図２及び図３を参照してより詳細に説明する。 (2.2) Configuration of Each Unit Next, each configuration of the control system 1, the host system 2, and the learning system 5 according to the present embodiment will be described in more detail with reference to FIGS. 2 and 3.
　制御システム１は、第１制御部１１と、第２制御部１２と、生成部１３と、復旧出力部１４と、下位通信部１５と、記憶部１６と、下位データベース１７と、を有している。このうち、第１制御部１１、第２制御部１２、生成部１３及び復旧出力部１４は、メモリ及びプロセッサを含むコンピュータシステムの一機能として実現される。 The control system 1 includes a first control unit 11, a second control unit 12, a generation unit 13, a restoration output unit 14, a lower communication unit 15, a storage unit 16, and a lower database 17. There is. Of these, the first control unit 11, the second control unit 12, the generation unit 13, and the recovery output unit 14 are realized as one function of a computer system including a memory and a processor.
　第１制御部１１は、上位システム２から通信により取得する予測情報に従って電力関連設備３を制御する。つまり、制御システム１と上位システム２との間の通信が成立し得る状態においては、上位システム２から制御システム１に送信される予測情報に従って、第１制御部１１が電力関連設備３を制御する。本開示でいう「予測情報」は、電力関連設備３の動作に関連する将来の予測を含む情報であって、例えば、電力関連設備３の動作に関する予測値の集合である。予測値の一例として、負荷での消費電力値（又は電力量）、電力関連設備３の出力電力値（又は電力量）、電力関連設備３の制御に用いる閾値、及び蓄電池３１の残容量等がある。また、予測情報は、これらの予測値の集合（組み合わせ）を、時間帯（例えば、１時間単位）ごとにリスト化した情報を含んでいる。さらに、予測情報は、電力関連設備３が導入されている施設の所有者等の需要家、電力会社又は電力アグリゲータが、ピークカット又はピークシフト等の要求を発する時間帯等も含んでいる。 The first control unit 11 controls the power-related equipment 3 according to the prediction information acquired from the host system 2 by communication. That is, in the state in which communication between the control system 1 and the host system 2 can be established, the first controller 11 controls the power-related equipment 3 according to the prediction information transmitted from the host system 2 to the control system 1. .. The "prediction information" referred to in the present disclosure is information including future predictions related to the operation of the electric power-related equipment 3, and is, for example, a set of predicted values related to the operation of the electric power-related equipment 3. As an example of the predicted value, the power consumption value (or the power amount) in the load, the output power value (or the power amount) of the power-related facility 3, the threshold value used for the control of the power-related facility 3, the remaining capacity of the storage battery 31, and the like are given. is there. Further, the prediction information includes information in which a set (combination) of these prediction values is listed for each time zone (for example, one hour unit). Furthermore, the prediction information also includes a time zone in which a customer such as an owner of a facility in which the power-related facility 3 is installed, a power company, or a power aggregator issues a request such as peak cut or peak shift.
　本実施形態では一例として、予測情報は、電力関連設備３における電力の需要と供給との少なくとも一方に関する情報を含んでいる。より詳細には、予測情報は、電力関連設備３における電力の需要と供給との両方に関する情報を含んでいる。電力関連設備３における電力の需要に関する情報の一例として、負荷（ＥＶ充電器３３を含む）での消費電力値（又は電力量）に係る情報がある。電力関連設備３における電力の供給に関する情報の一例として、電力関連設備３の出力電力値（又は電力量）に係る情報がある。つまり、本実施形態では、予測情報は、電力関連設備３の出力と入力との両方を予測するのに必要な情報である。 In the present embodiment, as an example, the prediction information includes information about at least one of demand and supply of power in the power-related facility 3. More specifically, the prediction information includes information on both the demand and supply of electric power in the electric power related equipment 3. As an example of information on the demand for electric power in the electric power-related equipment 3, there is information on the power consumption value (or electric energy) in the load (including the EV charger 33). As an example of information on the supply of electric power in the electric power-related equipment 3, there is information on the output electric power value (or electric energy) of the electric power-related equipment 3. That is, in the present embodiment, the prediction information is information necessary for predicting both the output and the input of the power-related equipment 3.
　これらの予測情報は、学習システム５における学習済みの分類器を用いて、上位システム２で生成される情報である。つまり、制御システム１は、上位システム２で生成された予測情報を、ネットワーク４を介して定期的又は不定期に取得しており、この予測情報に従って、第１制御部１１にて配下の電力関連設備３を制御する。その結果、制御システム１では、例えば、現在の負荷での消費電力値だけでなく、将来の負荷での消費電力値等を加味したきめ細やかな制御を、電力関連設備３に対して実行することが可能である。言い換えれば、制御システム１は、将来の予測に基づいて電力関連設備３を制御する予測制御機能を有している。 These pieces of prediction information are information generated by the higher-level system 2 using the learned classifier in the learning system 5. That is, the control system 1 periodically or irregularly acquires the prediction information generated by the higher-level system 2 via the network 4, and according to the prediction information, the power control related to the subordinate power in the first control unit 11 is performed. Control equipment 3. As a result, in the control system 1, for example, the power-related equipment 3 is subjected to delicate control that takes into consideration not only the power consumption value of the current load but also the power consumption value of the future load. Is possible. In other words, the control system 1 has a predictive control function that controls the power-related equipment 3 based on future predictions.
　第２制御部１２は、上位システム２との間の通信が遮断された状態で電力関連設備３を制御する。つまり、制御システム１と上位システム２との間の通信が遮断された状態においては、上位システム２から制御システム１に予測情報が送信されないため、第１制御部１１に代えて第２制御部１２が電力関連設備３を制御する。本開示でいう通信の「遮断」とは、正常な通信が成立しない状態を意味し、例えば、システム障害等により通信路が物理的又は論理的に遮断された状態の他、通信帯域の不足、又は輻輳の発生により正常な通信が成立しない状態等も、「遮断」に含む。特に、制御システム１と上位システム２との間の通信路が、ベストエフォート型のネットワーク４を含む場合には、通信帯域の不足又は輻輳の発生による、通信の遮断が突発的に生じ得る。 The second control unit 12 controls the power-related equipment 3 in a state where communication with the host system 2 is cut off. That is, in a state where the communication between the control system 1 and the host system 2 is cut off, the prediction information is not transmitted from the host system 2 to the control system 1, so that the second control unit 12 is used instead of the first control unit 11. Controls the power-related equipment 3. The “blocking” of communication in the present disclosure means a state in which normal communication is not established, and for example, a state in which a communication path is physically or logically blocked due to a system failure or the like, a shortage of a communication band, Alternatively, "blocking" also includes a state in which normal communication is not established due to the occurrence of congestion. In particular, when the communication path between the control system 1 and the host system 2 includes the best-effort network 4, communication cutoff may occur suddenly due to insufficient communication band or congestion.
　ここにおいて、第２制御部１２は、予測情報に相当する予備情報に基づいて電力関連設備３の制御を実行する。つまり、第２制御部１２は、制御システム１と上位システム２との間の通信が遮断された状態で、スタンドアローンで電力関連設備３を制御するため、予測情報ではなく、予測情報に相当する予備情報に基づいて電力関連設備３を制御する。 Here, the second control unit 12 executes control of the power-related equipment 3 based on the preliminary information corresponding to the prediction information. That is, since the second control unit 12 controls the power-related equipment 3 in a stand-alone manner in a state where the communication between the control system 1 and the host system 2 is cut off, the second control unit 12 corresponds to prediction information, not prediction information. The power-related equipment 3 is controlled based on the preliminary information.
　本開示でいう「予備情報」は、予測情報に相当する情報であればよく、予測情報と同一の情報を含んでいてもよいし、予測情報と同一の情報を含んでいなくてもよい。前者の例として、予測情報をミラーリングした情報が予備情報、後者の例としては、予測情報を生成するための学習器と同一の構成を持つ学習器にて生成された情報等がある。本開示でいう「ミラーリング」は、同期していることを意味し、例えば、予測情報をミラーリングした予備情報は、予測情報と同期している。そのため、予測情報をミラーリングした予備情報は、基本的に、予測情報と同一の情報を含んでおり、かつ予測情報が更新されれば予測情報に同期して更新されることになる。したがって、予測情報をミラーリングした予備情報は、同期が継続している限り、予測情報と同一の情報を含むことになる。 The “preliminary information” referred to in the present disclosure only needs to be information corresponding to the prediction information, and may include the same information as the prediction information, or may not include the same information as the prediction information. As an example of the former, information obtained by mirroring the prediction information is preliminary information, and as an example of the latter, there is information generated by a learning device having the same configuration as the learning device for generating the prediction information. "Mirroring" as used in the present disclosure means that the prediction information is synchronized. For example, the preliminary information obtained by mirroring the prediction information is synchronized with the prediction information. Therefore, the preliminary information mirrored with the prediction information basically includes the same information as the prediction information, and if the prediction information is updated, it will be updated in synchronization with the prediction information. Therefore, the preliminary information mirrored with the forecast information will include the same information as the forecast information as long as the synchronization continues.
　本実施形態では一例として、予備情報は、予測情報と同一の情報を含んでいる。より詳細には、予備情報は、予測情報をミラーリングした情報である。つまり、本実施形態では、第２制御部１２は、予測情報をミラーリングした情報を、予備情報として用いて、この予備情報に基づいて電力関連設備３の制御を実行する。そのため、第２制御部１２によれば、制御システム１と上位システム２との間の通信が遮断された状態であっても、予備情報を用いることで、予測情報に基づく第１制御部１１の制御に近い制御を実現することができる。 In the present embodiment, as an example, the preliminary information includes the same information as the prediction information. More specifically, the preliminary information is information that mirrors the prediction information. That is, in the present embodiment, the second control unit 12 uses the information obtained by mirroring the prediction information as the preliminary information, and executes the control of the power-related equipment 3 based on the preliminary information. Therefore, according to the second control unit 12, even when the communication between the control system 1 and the host system 2 is cut off, by using the preliminary information, the first control unit 11 based on the prediction information can be used. It is possible to realize control close to control.
　生成部１３は、上位システム２から取得した情報に基づいて予備情報を生成する。本実施形態では、上述したように予備情報は予測情報をミラーリングした情報である。そのため、生成部１３は、制御システム１が上位システム２から取得した予測情報を複製することで予備情報を生成し、制御システム１が上位システム２から予測情報を取得する度に予備情報を更新する。生成部１３で生成された予備情報は、下位データベース１７に随時格納される。 The generation unit 13 generates preliminary information based on the information acquired from the host system 2. In the present embodiment, as described above, the preliminary information is information obtained by mirroring the prediction information. Therefore, the generation unit 13 generates the preliminary information by copying the prediction information acquired by the control system 1 from the higher system 2, and updates the preliminary information each time the control system 1 acquires the prediction information from the higher system 2. .. The preliminary information generated by the generation unit 13 is stored in the lower database 17 as needed.
　復旧出力部１４は、上位システム２との通信が復旧したときに上位システム２に復旧情報を出力する。つまり、制御システム１と上位システム２との間の通信が遮断された状態においては、上述したように、第１制御部１１に代えて第２制御部１２が電力関連設備３を制御する。そして、通信が遮断された状態が解消され、つまり制御システム１と上位システム２との間の通信が復旧すると、今度は、復旧出力部１４が上位システム２に復旧情報を出力する。本開示でいう通信の「復旧」とは、通信が遮断された状態から、正常な通信が成立する状態に移行することを意味し、例えば、通信が遮断されていた要因となる事象が解消したときに、通信が「復旧」する。 The recovery output unit 14 outputs recovery information to the host system 2 when communication with the host system 2 is recovered. That is, in the state where the communication between the control system 1 and the host system 2 is cut off, the second control unit 12 controls the power-related equipment 3 instead of the first control unit 11 as described above. Then, when the state in which the communication is cut off is eliminated, that is, when the communication between the control system 1 and the upper system 2 is restored, the restoration output unit 14 outputs the restoration information to the upper system 2 this time. The “restoration” of communication in the present disclosure means a transition from a state in which communication is cut off to a state in which normal communication is established. For example, an event that causes the communication to be cut off has been resolved. Sometimes communication is "recovered".
　また、本開示でいう「復旧情報」は、少なくとも制御システム１と上位システム２との通信が復旧したときに、復旧出力部１４が上位システム２に出力する情報であればよく、その内容としては種々の内容が含まれ得る。例えば、単に通信が復旧したことを示すだけの情報であってもよいし、通信が復旧した時刻（日時）を示す情報であってもよい。 Further, the “recovery information” referred to in the present disclosure may be information that the recovery output unit 14 outputs to the higher system 2 at least when communication between the control system 1 and the higher system 2 is restored, and the content thereof is Various contents may be included. For example, it may be information that merely indicates that communication has been restored, or information that indicates the time (date and time) when communication has been restored.
　本実施形態では一例として、復旧情報は、上位システム２との通信の遮断期間に制御システム１で得られた履歴情報を含んでいる。ここでいう遮断期間は、制御システム１と上位システム２との通信が遮断された時点から、制御システム１と上位システム２との通信が復旧した時点までの期間である。つまり、通信の復旧時には、復旧出力部１４により、制御システム１と上位システム２との通信が遮断されていた間（遮断期間）に得られたデータが、履歴情報として上位システム２に出力される。これにより、例えば、遮断期間における、負荷での消費電力値（又は電力量）、及び電力関連設備３の出力電力値（又は電力量）等の、上位システム２が取得し損なった情報を、履歴情報として、通信の復旧時に上位システム２が取得可能となる。 In this embodiment, as an example, the recovery information includes the history information obtained by the control system 1 during the interruption period of communication with the host system 2. The cutoff period here is a period from the time when the communication between the control system 1 and the upper system 2 is cut off to the time when the communication between the control system 1 and the upper system 2 is restored. That is, when the communication is restored, the restoration output unit 14 outputs the data obtained while the communication between the control system 1 and the host system 2 is blocked (blocking period) to the host system 2 as history information. .. Thus, for example, information that the higher-level system 2 failed to acquire, such as the power consumption value (or power amount) in the load and the output power value (or power amount) of the power-related equipment 3 during the cutoff period, is recorded. As information, the host system 2 can be acquired when the communication is restored.
　また、本実施形態では、復旧情報は、予測情報を生成する分類器の再学習用の情報を含んでいる。つまり、上述したように、本実施形態では、学習システム５の分類器にて予測情報が生成されている。そのため、分類器の推定精度が向上することにより、分類器にて生成される予測情報の精度の向上を図ることが可能である。制御システム１と上位システム２との間の通信が遮断された期間においては、このような分類器の学習（再学習）に必要な情報についても、上位システム２にて取得できない可能性がある。本実施形態では、通信の復旧時には、復旧出力部１４により、制御システム１と上位システム２との通信が遮断されていた間（遮断期間）に得られたデータ（再学習用の情報）が、上位システム２に出力されることにより、学習システム５の再学習が可能となる。その結果、分類器にて生成される予測情報の精度の向上を図ることが可能である。 Further, in the present embodiment, the restoration information includes the information for re-learning the classifier that generates the prediction information. That is, as described above, in the present embodiment, the classifier of the learning system 5 generates the prediction information. Therefore, by improving the estimation accuracy of the classifier, it is possible to improve the accuracy of the prediction information generated by the classifier. During the period in which the communication between the control system 1 and the host system 2 is cut off, the host system 2 may not be able to acquire information necessary for learning (re-learning) of such a classifier. In the present embodiment, at the time of restoration of communication, the data (information for re-learning) obtained during the interruption of the communication between the control system 1 and the host system 2 (interruption period) by the restoration output unit 14 is The learning system 5 can be relearned by being output to the host system 2. As a result, it is possible to improve the accuracy of the prediction information generated by the classifier.
　下位通信部１５は、ネットワーク４を介して間接的に、上位システム２と通信する。ここで、下位通信部１５は、上位システム２から送信される予測情報を少なくとも受信可能である。下位通信部１５は、予測情報を定期的、不定期、又は制御システム１からの要求への応答として、上位システム２から受信する。また、下位通信部１５は、復旧出力部１４が出力する復旧情報を上位システム２に送信する機能も有している。 The lower communication unit 15 indirectly communicates with the upper system 2 via the network 4. Here, the lower communication unit 15 can at least receive the prediction information transmitted from the upper system 2. The lower communication unit 15 receives the prediction information from the upper system 2 regularly, irregularly, or as a response to a request from the control system 1. Further, the lower communication unit 15 also has a function of transmitting the recovery information output by the recovery output unit 14 to the higher system 2.
　記憶部１６は、少なくとも復旧情報に含まれる情報を記憶する。そのため、本実施形態では、記憶部１６は、履歴情報、及び再学習用の情報を、少なくとも記憶する。 The storage unit 16 stores at least the information included in the recovery information. Therefore, in the present embodiment, the storage unit 16 stores at least the history information and the relearning information.
　下位データベース１７は、上述したように、生成部１３で生成された予備情報を格納する。つまり、生成部１３が予備情報を生成（又は更新）する度に、下位データベース１７内の予備情報が更新されることになる。 The lower database 17 stores the preliminary information generated by the generation unit 13 as described above. That is, each time the generating unit 13 generates (or updates) the preliminary information, the preliminary information in the lower database 17 is updated.
　上位システム２は、予測部２１と、上位制御部２２と、上位通信部２３と、上位データベース２４と、を有している。このうち、予測部２１及び上位制御部２２は、メモリ及びプロセッサを含むコンピュータシステムの一機能として実現される。 The upper system 2 has a prediction unit 21, a higher control unit 22, a higher communication unit 23, and a higher database 24. Of these, the prediction unit 21 and the upper control unit 22 are realized as one function of a computer system including a memory and a processor.
　予測部２１は、予測情報を生成する。ここでは、予測部２１は、学習システム５の分類器を利用して、予測情報の生成を実行する。つまり、予測部２１は、人工知能（ＡＩ：Artificial Intelligence）を用いて、予測情報を生成する。予測部２１で生成された予測情報は、上位データベース２４に随時格納される。 Prediction unit 21 generates prediction information. Here, the prediction unit 21 uses the classifier of the learning system 5 to generate prediction information. That is, the prediction unit 21 generates prediction information by using artificial intelligence (AI). The prediction information generated by the prediction unit 21 is stored in the upper database 24 as needed.
　上位制御部２２は、上位システム２の各部の動作を制御する。例えば、上位制御部２２は、予測部２１での予測情報の生成を指示し、また上位通信部２３による制御システム１（下位通信部１５）との通信を制御する。 The host controller 22 controls the operation of each part of the host system 2. For example, the upper control unit 22 instructs the prediction unit 21 to generate prediction information, and also controls communication with the control system 1 (lower communication unit 15) by the upper communication unit 23.
　上位通信部２３は、ネットワーク４を介して間接的に、制御システム１（下位通信部１５）と通信する。ここで、上位通信部２３は、制御システム１に少なくとも予測情報を送信可能である。上位通信部２３は、予測情報を定期的、不定期、又は制御システム１からの要求への応答として、制御システム１に送信する。また、上位通信部２３は、復旧出力部１４が出力する復旧情報を制御システム１から受信する機能も有している。 The upper communication unit 23 indirectly communicates with the control system 1 (lower communication unit 15) via the network 4. Here, the upper communication unit 23 can transmit at least the prediction information to the control system 1. The host communication unit 23 transmits the prediction information to the control system 1 periodically, irregularly, or as a response to a request from the control system 1. The higher-level communication unit 23 also has a function of receiving the recovery information output by the recovery output unit 14 from the control system 1.
　上位データベース２４は、上述したように、予測部２１で生成された予測情報を格納する。つまり、予測部２１が予測情報を生成（又は更新）する度に、上位データベース２４内の予測情報が更新されることになる。 The upper database 24 stores the prediction information generated by the prediction unit 21 as described above. That is, each time the prediction unit 21 generates (or updates) the prediction information, the prediction information in the upper database 24 is updated.
　ここで、本実施形態では、上述したように予備情報は予測情報をミラーリングした情報である。そのため、下位データベース１７に格納されている予備情報は、上位データベース２４に格納されている予測情報に同期する。つまり、基本的には、下位データベース１７に格納されている予備情報は、上位データベース２４に格納されている予測情報と同一の情報を含んでおり、かつ予測情報が更新されれば予測情報に同期して更新されることになる。 Here, in this embodiment, as described above, the preliminary information is information obtained by mirroring the prediction information. Therefore, the preliminary information stored in the lower database 17 is synchronized with the prediction information stored in the upper database 24. That is, basically, the preliminary information stored in the lower database 17 includes the same information as the prediction information stored in the upper database 24, and is synchronized with the prediction information if the prediction information is updated. Will be updated.
　図３は、学習システム５の構成を概念的に示す概念図である。学習システム５は、機械学習により学習する機能を有している。ここでは、学習システム５は、上位システム２から与えられるデータを用いた深層学習（Deep Learning）により、学習済みの分類器を生成することと仮定する。図３では、上段が学習フェーズに係る学習システム５の構成を概念的に示し、下段が推論フェーズに係る学習システム５の構成を概念的に示す。 FIG. 3 is a conceptual diagram conceptually showing the configuration of the learning system 5. The learning system 5 has a function of learning by machine learning. Here, it is assumed that the learning system 5 generates a trained classifier by deep learning using the data given from the upper system 2. In FIG. 3, the upper part conceptually shows the configuration of the learning system 5 related to the learning phase, and the lower part conceptually shows the configuration of the learning system 5 related to the inference phase.
　学習システム５は、訓練データ（再学習用の情報を含む）を格納したデータベース５１を有している。学習システム５は、データベース５１内の訓練データに対して前処理を施すことにより、学習用データセット５２を生成する。学習システム５は、学習用データセット５２を学習器５３に入力する。学習器５３は、少なくとも電力関連設備３に関する予測情報を生成するための学習器であって、その実態は、例えば、ニューラルネットワークのネットワークモデル、及びハイパーパラメータ等を含む学習用のソフトウェアである。このような学習器５３に学習用データセット５２が入力される処理を繰り返すことで、学習器５３は、学習済モデル５４を生成する。 The learning system 5 has a database 51 that stores training data (including information for re-learning). The learning system 5 generates the learning data set 52 by preprocessing the training data in the database 51. The learning system 5 inputs the learning data set 52 to the learning device 53. The learning device 53 is a learning device for generating at least prediction information regarding the power-related equipment 3, and its actual state is, for example, a learning model including a network model of a neural network and hyperparameters. By repeating the process of inputting the learning data set 52 to the learning device 53, the learning device 53 generates the trained model 54.
　学習フェーズにおいて学習器５３が生成した学習済モデル５４が、学習器に実装されることにより、学習済みの分類器５５が生成される。そして、学習システム５は、学習済みの分類器５５に入力データが入力されることにより、分類器５５より出力データを出力する。ここで、分類器５５に、上位システム２から、例えば、電力関連設備３に関する実績情報が入力されることで、分類器５５は、この電力関連設備３に係る予測情報を上位システム２に出力する。ここでいう実績情報は、例えば、負荷での消費電力値（又は電力量）、電力関連設備３の出力電力値（又は電力量）、電力関連設備３の制御に用いる閾値、及び蓄電池３１の残容量等の実績値を含む。実績情報は、電力関連設備３におけるパワーコンディショナ３２の入力及び／又は出力電力値（又は電力量）の実績値、及び時刻情報等を含んでもよい。さらに、実績情報は、一例として、温度情報、ステータス情報及びエラー情報等の、電力関連設備３の各部（蓄電池３１、パワーコンディショナ３２又はＥＶ充電器３３等）の状態又は動作に関連する情報を含んでもよい。 The trained model 54 generated by the learner 53 in the learning phase is mounted on the learner to generate the trained classifier 55. Then, the learning system 5 outputs the output data from the classifier 55 when the input data is input to the learned classifier 55. Here, for example, when the actual information about the power-related equipment 3 is input from the higher-level system 2 to the classifier 55, the classifier 55 outputs the prediction information related to the power-related equipment 3 to the higher-level system 2. .. The performance information referred to here is, for example, the power consumption value (or power amount) in the load, the output power value (or power amount) of the power-related equipment 3, the threshold value used for controlling the power-related equipment 3, and the remaining capacity of the storage battery 31. Including actual values such as capacity. The actual information may include the actual value of the input and / or output power value (or electric energy) of the power conditioner 32 in the power-related equipment 3, time information, and the like. Furthermore, the record information includes, as an example, information related to the state or operation of each part (the storage battery 31, the power conditioner 32, the EV charger 33, or the like) of the power-related equipment 3 such as temperature information, status information, and error information. It may be included.
　（３）動作
　次に、本実施形態に係る制御システム１、及びそれを備える設備管理システム１０の動作について、図４及び図５を参照して詳細に説明する。 (3) Operation Next, the operation of the control system 1 according to the present embodiment and the equipment management system 10 including the same will be described in detail with reference to FIGS. 4 and 5.
　（３．１）基本動作
　図４は、本実施形態に係る制御システム１、及びそれを備える設備管理システム１０の動作の一例を示すシーケンス図である。図４では、制御システム１と上位システム２との間の通信が正常に成立する状態から、一時的に通信が遮断され、その後に通信が復旧する場合を想定する。さらに、制御システム１と上位システム２との間の通信が正常に成立する状態において、制御システム１は、定期的又は不定期に、予測情報のミラーリングにより予備情報を生成していることと仮定する。 (3.1) Basic Operation FIG. 4 is a sequence diagram showing an example of the operation of the control system 1 according to the present embodiment and the equipment management system 10 including the control system 1. In FIG. 4, it is assumed that the communication between the control system 1 and the host system 2 is normally established, the communication is temporarily interrupted, and then the communication is restored. Further, it is assumed that the control system 1 regularly or irregularly generates the preliminary information by mirroring the prediction information in a state where the communication between the control system 1 and the host system 2 is normally established. ..
　まず、制御システム１と上位システム２との間の通信が正常に成立する状態にあっては、制御システム１は、定期的、不定期、又は上位システム２からの要求への応答として、上位システム２に監視情報を送信する（Ｓ１）。ここでいう監視情報は、監視情報の送信元である制御システム１の配下の電力関連設備３に関する情報であって、上述した実績情報等を含む。つまり、監視情報は、例えば、負荷での消費電力値（又は電力量）、電力関連設備３の出力電力値（又は電力量）、電力関連設備３の制御に用いる閾値、及び蓄電池３１の残容量等の実績値を含む。さらに、監視情報は、電力関連設備３の異常（エラー）及び故障等に関する情報を含んでいてもよい。また、監視情報は、生成部１３で生成された予備情報に関連する情報、又は予備情報を含んでもよい。監視情報が予備情報（又は予備情報に関連する情報）を含むことで、例えば、監視情報を受信した上位システム２では、制御システム１で予備情報が生成されたことを確認することが可能となる。 First, when the communication between the control system 1 and the host system 2 is normally established, the control system 1 periodically, irregularly, or responds to a request from the host system 2 by the host system 2. The monitoring information is transmitted to 2 (S1). The monitoring information referred to here is information about the power-related equipment 3 under the control system 1 that is the transmission source of the monitoring information, and includes the above-mentioned actual information and the like. That is, the monitoring information is, for example, the power consumption value (or power amount) in the load, the output power value (or power amount) of the power-related equipment 3, the threshold value used for controlling the power-related equipment 3, and the remaining capacity of the storage battery 31. Including actual values such as. Furthermore, the monitoring information may include information regarding an abnormality (error) and a failure of the power-related equipment 3. Further, the monitoring information may include information related to the preliminary information generated by the generation unit 13 or preliminary information. By including the preliminary information (or information related to the preliminary information) in the monitoring information, for example, in the host system 2 that receives the monitoring information, it is possible to confirm that the control system 1 has generated the preliminary information. ..
　また、制御システム１と上位システム２との間の通信が正常に成立する状態にあっては、上位システム２は、定期的、不定期、又は制御システム１からの要求への応答として、制御システム１に予測情報を送信する（Ｓ２）。予測情報を受信した制御システム１は、予測情報のミラーリングにより、生成部１３にて予備情報を生成する（Ｓ３）。つまり、制御システム１は、上位システム２から受信した予測情報と同一の情報を含む予備情報を生成する。 Further, in a state where the communication between the control system 1 and the host system 2 is normally established, the host system 2 periodically, irregularly, or responds to a request from the control system 1 as a control system. The prediction information is transmitted to 1 (S2). The control system 1 that has received the prediction information generates preliminary information in the generation unit 13 by mirroring the prediction information (S3). That is, the control system 1 generates preliminary information including the same information as the prediction information received from the host system 2.
　そして、制御システム１は、上位システム２から受信した予測情報に従って、第１制御部１１にて、電力関連設備３を制御する（Ｓ４）。つまり、第１制御部１１が、上位システム２から通信により取得する予測情報に従って電力関連設備３を制御する、第１制御処理を実行する。このとき、制御システム１は、電力関連設備３に対して制御情報を送信することで、電力関連設備３を制御する（Ｓ５）。制御情報は、例えば、蓄電池３１の充電／放電の指示、パワーコンディショナ３２の出力の調整、及びＥＶ充電器３３の出力の調整等の制御のための情報を含んでいる。これにより、制御システム１では、例えば、現在の負荷での消費電力値だけでなく、将来の負荷での消費電力値等を加味したきめ細やかな制御を、電力関連設備３に対して実行することが可能である。言い換えれば、制御システム１は、予測制御機能により、将来の予測に基づいて電力関連設備３を制御する。 Then, the control system 1 controls the power-related equipment 3 by the first control unit 11 according to the prediction information received from the host system 2 (S4). That is, the first control unit 11 executes the first control process of controlling the power-related equipment 3 according to the prediction information acquired from the host system 2 by communication. At this time, the control system 1 controls the power-related equipment 3 by transmitting control information to the power-related equipment 3 (S5). The control information includes, for example, information for controlling charging/discharging the storage battery 31, adjusting the output of the power conditioner 32, adjusting the output of the EV charger 33, and the like. As a result, the control system 1 executes, for example, fine control on the power-related equipment 3 in consideration of not only the power consumption value of the present load but also the power consumption value of the future load. Is possible. In other words, the control system 1 controls the power-related equipment 3 based on the future prediction by the predictive control function.
　一方、制御システム１と上位システム２との間の通信が遮断されると（Ｓ６）、制御システム１は、上位システム２から予測情報を受信できなくなる。そこで、この状態においては、制御システム１は、予備情報に従って、第２制御部１２にて、電力関連設備３を制御する（Ｓ７）。つまり、第２制御部１２が、予測情報に相当する予備情報に基づいて電力関連設備３の制御を実行する、第２制御処理を実行する。このとき、制御システム１は、電力関連設備３に対して制御情報を送信することで、電力関連設備３を制御する（Ｓ８）。その結果、制御システム１と上位システム２との間の通信が遮断された状態であっても、制御システム１は、例えば、現在の負荷での消費電力値だけでなく、将来の負荷での消費電力値等を加味したきめ細やかな制御を、電力関連設備３に対して実行できる。 On the other hand, when the communication between the control system 1 and the host system 2 is cut off (S6), the control system 1 cannot receive the prediction information from the host system 2. Therefore, in this state, the control system 1 controls the power-related equipment 3 by the second control unit 12 according to the preliminary information (S7). That is, the second control unit 12 executes the second control process that executes the control of the power-related equipment 3 based on the preliminary information corresponding to the prediction information. At this time, the control system 1 controls the electric power-related equipment 3 by transmitting control information to the electric power-related equipment 3 (S8). As a result, even if the communication between the control system 1 and the host system 2 is cut off, the control system 1 may not only consume the power consumption value at the current load but also the power consumption at the future load, for example. Fine control that takes into account the power value and the like can be executed for the power-related equipment 3.
　したがって、制御システム１は、上位システム２との通信が正常に成立する状態にあっては勿論のこと、上位システム２との通信が遮断された状態においても、予測制御機能により、将来の予測に基づいて電力関連設備３を制御することが可能である。 Therefore, the control system 1 can predict the future by the predictive control function not only when the communication with the host system 2 is normally established but also when the communication with the host system 2 is cut off. It is possible to control the power-related equipment 3 based on this.
　また、制御システム１と上位システム２との間の通信が復旧すると（Ｓ９）、制御システム１は、復旧出力部１４にて、上位システム２に復旧情報を送信する（Ｓ１０）。このとき送信される復旧情報は、上位システム２との通信の遮断期間に制御システム１で得られた履歴情報、及び予測情報を生成する分類器の再学習用の情報を含んでいる。そのため、復旧情報を受けた上位システム２は、復旧情報を学習システム５に入力することにより、学習システム５の分類器の再学習を行い、より適切な分類器に更新することが可能である。このようにして更新された分類器は、再学習が行われない場合に比べて、予測情報の推定精度が向上する。 Further, when the communication between the control system 1 and the host system 2 is restored (S9), the control system 1 causes the restoration output unit 14 to transmit the restoration information to the host system 2 (S10). The restoration information transmitted at this time includes the history information obtained by the control system 1 during the period in which the communication with the host system 2 is cut off, and the re-learning information of the classifier that generates the prediction information. Therefore, the higher-level system 2 that has received the restoration information can re-learn the classifier of the learning system 5 by inputting the restoration information to the learning system 5 and update it to a more appropriate classifier. The classifier updated in this way improves the estimation accuracy of prediction information as compared with the case where relearning is not performed.
　その後は、上記Ｓ１及びＳ２と同様に、制御システム１は、上位システム２に監視情報を送信し（Ｓ１１）、上位システム２は、制御システム１に予測情報を送信する（Ｓ１２）。そして、上記Ｓ３以降の処理が、繰り返し行われる。 After that, similarly to S1 and S2 described above, the control system 1 transmits the monitoring information to the upper system 2 (S11), and the upper system 2 transmits the prediction information to the control system 1 (S12). Then, the processing from S3 onward is repeatedly performed.
　ところで、本実施形態に係る制御システム１は、上述したように、上位システム２との通信が遮断されたとしても、予備情報に基づいて電力関連設備３の制御を継続できる。そのため、制御システム１と上位システム２との間の通信が遮断されたことに、ユーザ（オペレータ及びエンジニアを含む）が気付くタイミングが遅れる可能性がある。そこで、制御システム１又は上位システム２は、制御システム１が第２制御処理を実行していることを報知する報知手段を有することが好ましい。報知手段は、制御システム１及び／又は上位システム２に設けられていてもよいし、電力関連設備３に設けられていてもよい。あるいは、オペレータが所持する情報端末６、又はエンジニアが所持する情報端末７に、報知手段が設けられてもよい。 By the way, the control system 1 according to the present embodiment can continue the control of the power-related equipment 3 based on the preliminary information even if the communication with the host system 2 is cut off, as described above. Therefore, there is a possibility that the timing at which the user (including the operator and the engineer) notices that the communication between the control system 1 and the host system 2 is cut off may be delayed. Therefore, it is preferable that the control system 1 or the host system 2 has a notifying unit that notifies that the control system 1 is executing the second control process. The notification means may be provided in the control system 1 and / or the higher-level system 2, or may be provided in the power-related equipment 3. Alternatively, the information terminal 6 possessed by the operator or the information terminal 7 possessed by the engineer may be provided with the notification means.
　このように、制御システム１が第２制御処理を実行していることを報知することで、制御システム１と上位システム２との間の通信が遮断されたことをユーザに知らせることができる。結果的に、制御システム１と上位システム２との間の通信の早期の復旧を促すことにもつながる。 In this way, by notifying that the control system 1 is executing the second control process, it is possible to notify the user that the communication between the control system 1 and the host system 2 has been cut off. As a result, it also promotes early restoration of communication between the control system 1 and the host system 2.
　（３．２）フローチャート
　図５は、本実施形態に係る制御システム１の動作の一例を示すフローチャートである。 (3.2) Flowchart FIG. 5 is a flowchart showing an example of the operation of the control system 1 according to the present embodiment.
　制御システム１は、図５に示すように、制御システム１と上位システム２との間の通信の遮断が発生したか否かを判断する（Ｓ２１）。ここで、制御システム１と上位システム２との間の通信が遮断されていなければ、つまり通信が正常に成立する状態にあれば（Ｓ２１：Ｎｏ）、制御システム１は、第１制御処理を実行する（Ｓ２２）。第１制御処理では、制御システム１は、上位システム２から受信した予測情報に従って、第１制御部１１にて、上位システム２から通信により取得する予測情報に従って電力関連設備３を制御する。その後、制御システム１は、処理Ｓ２１に移行する。 As shown in FIG. 5, the control system 1 determines whether or not the communication between the control system 1 and the host system 2 is interrupted (S21). Here, if the communication between the control system 1 and the host system 2 is not interrupted, that is, if the communication is normally established (S21: No), the control system 1 executes the first control process. (S22). In the first control process, the control system 1 controls the power-related equipment 3 in accordance with the prediction information received from the host system 2 by the first control unit 11 according to the prediction information received from the host system 2. After that, the control system 1 shifts to the process S21.
　一方、制御システム１と上位システム２との間の通信が遮断されると（Ｓ２１：Ｙｅｓ）、制御システム１は、第２制御処理を実行する（Ｓ２３）。第２制御処理では、制御システム１は、第２制御部１２にて、予測情報に相当する予備情報に基づいて電力関連設備３を制御する。その後、制御システム１は、通信が復旧したか否かを判断する（Ｓ２４）。ここで、制御システム１と上位システム２との間の通信が復旧すれば、つまり通信が正常に成立する状態になれば（Ｓ２４：Ｙｅｓ）、制御システム１は、復旧出力部１４にて復旧情報を出力する（Ｓ２５）。このとき、制御システム１は、復旧出力部１４にて、上位システム２に復旧情報を送信する。その後、制御システム１は、処理Ｓ２１に移行する。 On the other hand, when the communication between the control system 1 and the host system 2 is cut off (S21: Yes), the control system 1 executes the second control process (S23). In the second control process, the control system 1 controls the power-related equipment 3 by the second control unit 12 based on the preliminary information corresponding to the prediction information. After that, the control system 1 determines whether the communication is restored (S24). Here, if the communication between the control system 1 and the host system 2 is restored, that is, if the communication is normally established (S24: Yes), the control system 1 causes the restoration output unit 14 to restore the restoration information. Is output (S25). At this time, the control system 1 transmits the recovery information to the host system 2 at the recovery output unit 14. Then, the control system 1 moves to process S21.
　一方、制御システム１と上位システム２との間の通信が復旧しなければ、つまり通信が遮断された状態が継続していれば（Ｓ２４：Ｎｏ）、制御システム１は、第２制御処理Ｓ２３を繰り返し実行する。 On the other hand, if the communication between the control system 1 and the host system 2 is not restored, that is, if the state in which the communication is interrupted continues (S24: No), the control system 1 executes the second control process S23. Execute repeatedly.
