Description

本発明は、各分電盤の分岐回路で計測された計測データを、負荷名称とともにサーバに記録する計測システムに関するものである。 The present invention relates to a measurement system that records measurement data measured by a branch circuit of each distribution board in a server together with a load name.

住宅用分電盤に電流計測手段を組み込み、検出された負荷ごとの消費電力を監視するＨＥＭＳ（ホーム・エネルギマネジメントシステム）は、特許文献１に示されるように、従来から知られている。また近年ではＨＥＭＳのみならず、ＢＥＭＳ（ビルディング・エネルギマネジメントシステム）などによりビル全体の電力を監視するシステムも普及している。 As shown in Patent Document 1, a HEMS (Home Energy Management System) that incorporates a current measuring means into a residential distribution board and monitors the power consumption of each detected load has been conventionally known. In recent years, not only HEMS but also a system for monitoring the electric power of the entire building by BEMS (Building Energy Management System) or the like has become widespread.

これらのエネルギマネジメントシステムでは、ユーザは自己の分電盤のどの分岐ブレーカがどの負荷に接続されているかということ予め入力する必要がある。また、複数の分電盤の消費電力を監視する場合にも、各分電盤の分岐回路に対応した負荷ごとに消費電力を監視する必要があり、分岐回路に対応した負荷名称をアプリケーション等で入力する必要がある。 In these energy management systems, the user needs to input in advance which branch breaker of his / her distribution board is connected to which load. Also, when monitoring the power consumption of multiple distribution boards, it is necessary to monitor the power consumption for each load corresponding to the branch circuit of each distribution board, and the load name corresponding to the branch circuit can be used in applications, etc. Must be entered.

しかし、一般のユーザにとっては自己の分電盤のどの分岐回路がどの負荷に接続されているかを確認することは容易ではない。また分岐ごとの負荷名称が明らかになったとしても、アプリケーションへの入力は面倒であり、多くの時間と手数を要するという問題があった。さらに不慣れな入力時に、ミスが発生する可能性もあった。 However, it is not easy for a general user to confirm which branch circuit of his / her own distribution board is connected to which load. Moreover, even if the load name for each branch is clarified, there is a problem that inputting to the application is troublesome and requires a lot of time and effort. In addition, mistakes could occur during unfamiliar input.

従って本発明の目的は上記した従来の問題点を解決し、各分電盤の分岐回路で計測された計測データを、負荷名称とともにサーバに記録する計測システムであって、負荷名称の入力を簡便かつ正確に行うことができる計測システムを提供することである。 Therefore, an object of the present invention is a measurement system that solves the above-mentioned conventional problems and records the measurement data measured by the branch circuit of each distribution board on the server together with the load name, and it is easy to input the load name. And to provide a measurement system that can be performed accurately.

上記の課題を解決するためになされた本発明の計測システムは、分電盤の分岐回路ごとの計測データを蓄積手段に記録する計測システムであって、分電盤は、分岐回路ごとに計測データを測定する測定手段と、蓄積手段と、測定した計測データとともに、分岐回路ごとに設定される分岐番号を蓄積手段へ送信する送信手段とを備え、蓄積手段は、負荷名称ラベル作成手段で入力された負荷名称を取り込み、分岐回路ごとに入力される負荷名称と対応する分岐回路の該計測データとを結びつけて記録するものであり、前記負荷名称ラベル作成手段は、分電盤の設計段階あるいは施工段階において、分岐回路の負荷名称を分電盤の設計者あるいは施工業者が対応する位置に入力し、入力した内容を負荷名称ラベルとしてプリントアウトするものであって、入力した負荷名称とともに、対応する分岐番号を蓄積手段に送信する負荷名称送信手段を備えたものであることを特徴とするものである。 The measurement system of the present invention made to solve the above problems is a measurement system that records the measurement data for each branch circuit of the distribution board in the storage means, and the distribution board is the measurement data for each branch circuit. measuring means for measuring, a storage unit, together with the measured measurement data, and transmission means for transmitting the branch number is set for each branch circuit to the storage means, the storage means, input load name label producing means The load name is taken in, and the load name input for each branch circuit and the measurement data of the corresponding branch circuit are linked and recorded. The load name label creation means is at the design stage of the distribution board or At the construction stage, the load name of the branch circuit is input by the designer or contractor of the distribution board at the corresponding position, and the input content is printed out as a load name label. It is characterized in that it is provided with a load name transmitting means for transmitting the branch number to be performed to the storage means .

また本発明の計測システムは、通信手段を介して複数の分電盤と接続され、送信手段は、測定した計測データとともに、分電盤ごとに定められる分電盤固有情報を蓄積手段に送信し、負荷名称ラベル作成手段は、入力した負荷名称とともに、分電盤ごとに定められる分電盤固有情報を蓄積手段に送信し、蓄積手段は、対応する分電盤の計測データと負荷名称とを分岐番号及び分電盤固有情報で結びつけて記録する統合手段を備えることが好ましい。 Further, the measurement system of the present invention is connected to a plurality of distribution boards via a communication means, and the transmission means transmits the measured measurement data and the distribution board-specific information determined for each distribution board to the storage means. , The load name label creation means transmits the input load name and the distribution board specific information determined for each distribution board to the storage means, and the storage means transfers the measurement data and the load name of the corresponding distribution board. It is preferable to provide an integrated means for connecting and recording the branch number and the distribution board unique information.

本発明によれば、分電盤の設計段階あるいは施工段階において、分電盤の負荷名称ラベルを作成する負荷名称作成手段に入力されたデータを用いて 分電盤の分岐ブレーカごとの消費電力と負荷名称とを自動的に結びつけて記録することができるので、分電盤のユーザによる負荷名称の入力は不要となり、時間や手数を省くことができるのみならず、手入力のように入力ミスが生じることもない。 According to the present invention, at the design stage or the construction stage of the distribution board, the power consumption of each branch breaker of the distribution board is determined by using the data input to the load name creating means for creating the load name label of the distribution board.

以下に本発明の実施形態を説明する。
図１は分電盤１の模式図であり、２は主幹ブレーカ、３は主幹ブレーカ２の二次側母線に接続された分岐ブレーカである。図１では説明を簡略化するために分岐ブレーカ３の数は５個としてあるが、実際にはさらに多数の分岐ブレーカ３が接続されており、家庭用の分電盤の場合には、冷蔵庫、照明器具、洗濯機、空調設備、パソコン等の様々な負荷に、分岐ブレーカ３を通じて電力を供給している。 An embodiment of the present invention will be described below.
FIG. 1 is a schematic view of the distribution board 1, reference numeral 2 denotes a main breaker, and 3 is a branch breaker connected to the secondary bus of the main breaker 2. In FIG. 1, the number of branch breakers 3 is set to 5 for the sake of brevity, but in reality, a larger number of branch breakers 3 are connected, and in the case of a household distribution board, a refrigerator is used. Electric power is supplied to various loads such as lighting equipment, washing machines, air conditioners, and personal computers through the branch breaker 3.

各分岐ブレーカ３に流れる電流値、すなわち各分岐回路の負荷の消費電流は、ＣＴその他の電流計測手段４によって分岐回路ごとに測定され、その計測データは測定手段５に集められる。測定手段５は電流計測手段４によって測定した消費電流と母線バー等で取得した電圧情報とを演算して消費電力データ（計測データ）として分岐番号とともに送信手段６に送信する。図２に示すように、分電盤１に組み込まれた送信手段６は、その分電盤１の分岐ごとの消費電流または消費電力をＥＭＳ（図示せず）を介してインターネットなどの通信回線７を経由して蓄積手段であるサーバ８に送信する。 The current value flowing through each branch breaker 3, that is, the current consumption of the load of each branch circuit is measured for each branch circuit by CT or other current measuring means 4, and the measurement data is collected by the measuring means 5. The measuring means 5 calculates the current consumption measured by the current measuring means 4 and the voltage information acquired by the bus bar or the like, and transmits the power consumption data (measurement data) together with the branch number to the transmitting means 6. As shown in FIG. 2, the transmission means 6 incorporated in the distribution board 1 determines the current consumption or power consumption of each branch of the distribution board 1 via an EMS (not shown) in a communication line 7 such as the Internet. It is transmitted to the server 8 which is a storage means via.

分電盤１には分電盤を識別するための分電盤固有情報（シリアル番号等）が付与されており、送信手段６は図１の右下に示すようにこの固有情報とともに、分岐ごとの負荷の消費電流をサーバ８に送信する。分電盤固有情報を送信手段６に入力する方法は特に限定されないが、例えば、分電盤個体の筐体内部に表示されている分電盤固有情報を、居住者等が送信手段６に入力するものであってもよいし、予め送信手段６に記憶されていてもよい。 Distribution board unique information (serial number, etc.) for identifying the distribution board is assigned to the distribution board 1, and the transmission means 6 is provided with this unique information together with each branch as shown in the lower right of FIG. The current consumption of the load is transmitted to the server 8. The method of inputting the distribution board-specific information to the transmission means 6 is not particularly limited. For example, a resident or the like inputs the distribution board-specific information displayed inside the housing of the individual distribution board to the transmission means 6. It may be stored in the transmission means 6 in advance.

さらに各分電盤１には分岐回路ごとに分岐番号が付与されている。分岐番号は、予め測定手段５のＣＴを接続するポートに割り当てられていて、ＣＴは分岐番号に対応した分岐回路に取り付けられる。分電盤の分岐番号は、後述する負荷名称作成ソフトの負荷名称に対応する分岐番号と一致させる必要があり、例えば、ＣＴは主幹ブレーカ２に近い側に配置された分岐ブレーカ３から順に割り振られる。 Further, a branch number is assigned to each distribution board 1 for each branch circuit. The branch number is assigned to the port connecting the CT of the measuring means 5 in advance, and the CT is attached to the branch circuit corresponding to the branch number. The branch number of the distribution board needs to match the branch number corresponding to the load name of the load name creation software described later. For example, CT is assigned in order from the branch breaker 3 arranged on the side closer to the main breaker 2. ..

なお、分電盤識別用の固有情報及び分岐番号としては、英数字で構成される文字列が代表的なものであるが、識別可能であればどのような構成であっても差し支えない。このようにして、分電盤１の消費電流（計測データ）は、送信手段６によって分電盤固有情報と分岐番号とともに蓄積手段であるサーバ８に蓄積される。 As the unique information and the branch number for identifying the distribution board, a character string composed of alphanumeric characters is typical, but any configuration may be used as long as it can be identified. In this way, the current consumption (measurement data) of the distribution board 1 is stored by the transmission means 6 in the server 8 which is the storage means together with the distribution board unique information and the branch number.

一方、分電盤１にはどの分岐にどのような負荷が接続されているかを示す図３に示すような負荷名称ラベル９が設けられている。この負荷名称ラベル９は古い分電盤では人手によって作成されていたが、最近の分電盤では負荷名称作成ソフト（負荷名称ラベル作成手段）を用いて作成されプリントアウトされ分電盤に添付されることが増えている。 On the other hand, the distribution board 1 is provided with a load name label 9 as shown in FIG. 3, which indicates what kind of load is connected to which branch. This load name label 9 was manually created on an old distribution board, but on a recent distribution board, it is created using load name creation software (load name label creation means), printed out, and attached to the distribution board. Is increasing.

このような負荷名称作成ソフトの一例は、本出願人の特開２０１５−２０１１１７号に示されている。この公報記載の負荷名称作成ソフトは、ユーザが分電盤１の内部機器を指定しながら分電盤を設計する作業と同時に、どの分岐番号の分岐ブレーカ３がどの負荷に接続されるかを特定し、分岐回路ごとの負荷名称ラベルの作成までを行えるようになっている。なお、負荷名称ラベルには分岐番号が印字されていることが好ましい。 An example of such load name creation software is shown in Japanese Patent Application Laid-Open No. 2015-201117 of the present applicant. The load name creation software described in this publication specifies which branch number branch breaker 3 is connected to which load at the same time as the user designs the distribution board while designating the internal equipment of the distribution board 1. However, it is possible to create a load name label for each branch circuit. It is preferable that the branch number is printed on the load name label.

図４に負荷名称作成ソフトの画面（負荷名称入力手段）を例示する。この図４の例では、分岐番号１の分岐には負荷Ａが接続され、分岐番号２の分岐には負荷Ｂが接続され、以下同様に各分岐番号と負荷名称との関係が入力されている。なお本発明においては、負荷名称作成ソフトの具体的内容については特に限定されるものではなく、分電盤１の分岐番号と負荷名称との対応関係がデータとして入力されていればよい。 FIG. 4 illustrates a screen (load name input means) of the load name creation software. In the example of FIG. 4, the load A is connected to the branch of the branch number 1, the load B is connected to the branch of the branch number 2, and the relationship between each branch number and the load name is input in the same manner. .. In the present invention, the specific content of the load name creation software is not particularly limited, and the correspondence between the branch number of the distribution board 1 and the load name may be input as data.

従来、負荷名称作成ソフトは分電盤の施工業者によって負荷名称ラベルの作成だけに使用されており、それ以外の目的で使用されたことはない。しかし本発明では、負荷名称作成ソフトに入力済みのデータを計測システムで利用するため、計測システムの蓄積手段であるサーバ８に送信する。すなわち、負荷名称作成ソフトは負荷名称送信手段を備えていて、分電盤識別用の分電盤固有情報（シリアル番号等）および分岐番号を負荷名称と併せてサーバ８に送信する。この分電盤固有情報は負荷名称作成ソフトに予め入力されているが、入力されていない場合には送信時に付け加えればよい。例えば、分電盤個体や仕様図面に表示されている分電盤固有情報を、分電盤の施工業者等が入力してもよい。 Conventionally, load name creation software has been used only for creating load name labels by distribution board contractors, and has never been used for any other purpose. However, in the present invention, in order to use the data already input to the load name creation software in the measurement system, the data is transmitted to the server 8 which is the storage means of the measurement system. That is, the load name creation software is provided with a load name transmission means, and transmits distribution board specific information (serial number or the like) and a branch number for distribution board identification to the server 8 together with the load name. This distribution board-specific information is input in advance in the load name creation software, but if it is not input, it may be added at the time of transmission. For example, the distribution board contractor or the like may input the distribution board specific information displayed on the individual distribution board or the specification drawing.

図２に示したように、本発明の計測システムのサーバ８には、非常に多数の分電盤１が接続されている。上記したように負荷名称作成ソフトに入力済みのデータをサーバ８に送信すると、サーバ８の統合手段は、図５に示すように、計測システムと負荷名称作成ソフトとに入力された分電盤識別用の分電盤固有情報を用いて各分電盤の計測データと負荷名称との結びつけを行うために、負荷名称作成ソフトから送信された分岐番号と負荷名称のデータを取り込む。このようにして、サーバ８は分電盤を特定し、特定された分岐番号と負荷名称との対応関係が計測システムにデータ入力され蓄積されたこととなる。 As shown in FIG. 2, a large number of distribution boards 1 are connected to the server 8 of the measurement system of the present invention. When the data already input to the load name creation software is transmitted to the server 8 as described above, the integration means of the server 8 identifies the distribution board input to the measurement system and the load name creation software as shown in FIG. In order to link the measurement data of each distribution board with the load name using the distribution board specific information for, the branch number and load name data transmitted from the load name creation software are taken in. In this way, the server 8 identifies the distribution board, and the correspondence between the specified branch number and the load name is input to the measurement system and accumulated.

計測システムのサーバ８には、分電盤１の送信手段６によって分電盤固有情報と分岐番号とともに各分岐ブレーカ３に流れる電流値または分岐回路の消費電力データが送信される。サーバ８の統合手段で各分電盤の計測データと負荷名称との紐付けを結びつけをして記録することにより、どの分電盤１のどの分岐に接続されたどの負荷にどれほどの電流が流れているかをリアルタイムで把握し、消費電力の表示や、電力需要ピーク時の消費電力の抑制など、様々な制御を行うことができる。また日付データや気象条件等を合わせて時系列的に記憶することで、ビッグデータを負荷の種類ごとに区別し、分析活用することも可能である。 The transmission means 6 of the distribution board 1 transmits the distribution board specific information and the branch number as well as the current value flowing through each branch breaker 3 or the power consumption data of the branch circuit to the server 8 of the measurement system. By linking and recording the measurement data of each distribution board and the load name by the integrated means of the server 8, how much current flows to which load connected to which branch of which distribution board 1. It is possible to grasp in real time whether or not the power is being used, and perform various controls such as displaying power consumption and suppressing power consumption during peak power demand. It is also possible to distinguish big data for each type of load and analyze and utilize it by storing date data, weather conditions, etc. in chronological order.

なお、負荷名称作成ソフトから送信されてきたデータを受信するための専用のサーバを設置してもよいが、そのデータは最終的には計測システムのサーバ８において統合されるため、実質的にはサーバ８に直接送信した場合と同様となる。 A dedicated server for receiving the data transmitted from the load name creation software may be installed, but since the data is finally integrated in the server 8 of the measurement system, it is practically This is the same as when the data is sent directly to the server 8.

上記した実施形態では、分電盤１の分岐ごとの消費電力を計測しサーバ８に蓄積したが、その他の計測データ（例えば電圧、電流、力率、周波数、高調波など）を分岐ごとに計測し、同様に分岐番号と負荷名称とともに蓄積手段に送信することもできる。蓄積手段は、分電盤１の分岐回路ごとの計測データと負荷名称とを分岐番号を基に結びつけて蓄積する統合手段を備え、計測データの蓄積を行う。 In the above embodiment, the power consumption of each branch of the distribution board 1 is measured and stored in the server 8, but other measurement data (for example, voltage, current, power factor, frequency, harmonics, etc.) is measured for each branch. However, it can also be sent to the storage means together with the branch number and the load name. The storage means includes an integrated means for connecting the measurement data for each branch circuit of the distribution board 1 and the load name based on the branch number and storing the measurement data.

上記したように、本発明においては負荷名称ラベルの作成のために負荷名称作成ソフトに入力したデータを利用して計測システムへの負荷名称の入力を行うので、分電盤のユーザによる負荷名称の入力は不要となり、時間や手数を省くことができる利点がある。 As described above, in the present invention, the load name is input to the measurement system by using the data input to the load name creation software for creating the load name label, so that the load name by the user of the distribution board is input. There is an advantage that input is not required and time and labor can be saved.
