制御部１０４は、受変電設備１００の各部の動作を制御する。制御部１０４は、例えばＣＰＵ（Central Processing Unit）等のプロセッサ及びＲＡＭ（Random Access Memory）を備えた装置により実行される。制御部１０４は、無線通信プログラムを実行することによって、状態取得部１４１、通信制御部１４２及び受信強度判定部１４３として機能する。 The control unit 104 controls the operation of each unit of the power receiving / transforming facility 100. The control unit 104 is executed by a device including a processor such as a CPU (Central Processing Unit) and a RAM (Random Access Memory), for example. The control unit 104 functions as a state acquisition unit 141, a communication control unit 142, and a reception strength determination unit 143 by executing a wireless communication program.

状態取得部１４１は、受変電設備１００の動作状態に関する状態情報を取得する。具体的には、状態取得部１４１は、受変電設備１００に設けられた電気機器から接点信号又は伝送信号等の信号を取得する。電気機器からの信号は、状態情報を含む。電気機器からの信号は、状態信号、故障信号又は計測信号等である。状態情報は、状態信号、故障信号又は計測信号等の信号に含まれる情報やデータである。状態信号は、電気機器の状態（例えば、電源オン、電源オフ又は故障）を示す信号である。故障信号は、電気機器に故障が発生した状態であること示す信号である。計測信号は、電流、電圧、電力、温度及び湿度等の電気機器に関する計測データを示す信号である。状態取得部１４１は、所定のタイミングで信号を取得する。例えば、状態取得部１４１は、電気機器の状態に変化が生じた場合に状態信号を取得してもよい。状態取得部１４１は、電気機器に故障が生じた場合に故障信号を取得してもよい。状態取得部１４１は、所定の時間間隔で計測信号を取得してもよい。状態取得部１４１は、受変電設備１００に設けられた電気機器毎に信号を取得する。この場合、信号は、電気機器に対応付けられた所定の情報を含む。所定の情報は、文字や数字等を組み合わせた情報であってもよい。所定の情報は電気機器を識別できる情報であればどのような情報であってもよい。すなわち、状態取得部１４１は、電気機器の台数に応じた複数の状態情報を取得する。状態取得部１４１は、取得した接点信号又は伝送信号を通信制御部１４２に出力する。 The state acquisition unit 141 acquires state information regarding the operating state of the power receiving / transforming facility 100. Specifically, the state acquisition unit 141 acquires a signal such as a contact signal or a transmission signal from an electric device provided in the power receiving / transforming facility 100. Signals from electrical equipment include state information. The signal from the electric device is a state signal, a failure signal, a measurement signal, or the like. The state information is information or data included in a signal such as a state signal, a failure signal, or a measurement signal. The status signal is a signal indicating the status of the electric device (for example, power on, power off, or failure). The failure signal is a signal indicating that a failure has occurred in an electric device. The measurement signal is a signal indicating measurement data related to electrical equipment such as current, voltage, electric power, temperature, and humidity. The state acquisition unit 141 acquires a signal at a predetermined timing. For example, the state acquisition unit 141 may acquire a state signal when a change occurs in the state of the electric device. The state acquisition unit 141 may acquire a failure signal when a failure occurs in an electric device. The state acquisition unit 141 may acquire measurement signals at predetermined time intervals. The state acquisition unit 141 acquires a signal for each electric device provided in the power receiving / transforming facility 100. In this case, the signal includes predetermined information associated with the electrical device. The predetermined information may be information that is a combination of letters, numbers, and the like. The predetermined information may be any information as long as it can identify the electric device. That is, the state acquisition unit 141 acquires a plurality of state information according to the number of electric devices. The state acquisition unit 141 outputs the acquired contact signal or transmission signal to the communication control unit 142.

通信制御部１４２は、所定の通信プログラムを実行することによって、他の装置と無線通信を行う。他の装置とは、例えば他の受変電設備１００又は無線通信装置２００等の電気室１０に設けられた装置である。第１の実施形態では、通信制御部１４２は、状態取得部１４１によって取得された信号を無線通信部１０１を介して無線通信装置２００に送信する。また、通信制御部１４２は、無線通信装置２００によって送信された信号を無線通信部１０１を介して受信する。 The communication control unit 142 performs wireless communication with another device by executing a predetermined communication program. The other device is, for example, a device provided in an electric room 10 such as another power receiving / transforming facility 100 or a wireless communication device 200. In the first embodiment, the communication control unit 142 transmits the signal acquired by the state acquisition unit 141 to the wireless communication device 200 via the wireless communication unit 101. Further, the communication control unit 142 receives the signal transmitted by the wireless communication device 200 via the wireless communication unit 101.

まず、通信制御部１４２が無線通信装置２００に信号を送信する場合について説明する。具体的には、通信制御部１４２は、状態取得部１４１から信号を受け付ける。通信制御部１４２は、設定記憶部１０３に記憶された情報に基づいて、受け付けた信号に対して監視制御装置３００に送信される信号であるか否かを判定する。受け付けた信号が監視制御装置３００に送信されない信号である場合、通信制御部１４２は、受け付けた信号を破棄する。受け付けた信号が監視制御装置３００に送信される信号である場合、通信制御部１４２は、受け付けた信号と受変電設備１００の識別情報と対応付ける。通信制御部１４２は、受け付けた信号と受変電設備１００の識別情報とを暗号化する。通信制御部１４２は、設定記憶部１０３に記憶された暗号化方式に基づいて暗号化してもよい。通信制御部１４２は、受信強度判定部１４３によって決定された受信強度が所定の閾値以上である場合に、暗号化された情報を送信する。通信制御部１４２は、無線通信部１０１を介して無線通信装置２００に暗号化された情報を送信する。また、通信制御部１４２は、複数の信号を受け付けた場合、複数の信号をまとめて無線通信装置２００に送信してもよい。 First, a case where the communication control unit 142 transmits a signal to the wireless communication device 200 will be described. Specifically, the communication control unit 142 receives a signal from the state acquisition unit 141. The communication control unit 142 determines whether or not the received signal is a signal transmitted to the monitoring control device 300 based on the information stored in the setting storage unit 103. When the received signal is a signal that is not transmitted to the monitoring control device 300, the communication control unit 142 discards the received signal. When the received signal is a signal transmitted to the monitoring control device 300, the communication control unit 142 associates the received signal with the identification information of the power receiving / transforming equipment 100. The communication control unit 142 encrypts the received signal and the identification information of the power receiving / transforming equipment 100. The communication control unit 142 may be encrypted based on the encryption method stored in the setting storage unit 103. The communication control unit 142 transmits the encrypted information when the reception strength determined by the reception strength determination unit 143 is equal to or higher than a predetermined threshold value.

The monitoring control device 300 receives the transmitted signal. The monitoring control device 300 outputs the state of the power receiving / transforming equipment based on the received signal. In this way, the power receiving / transforming equipment 100 can transmit a signal to the monitoring control device 300 by using wireless communication. Therefore, even when the monitoring control device 300 is provided at a distance, the power receiving / transforming equipment 100 can transmit a signal without laying a monitoring control cable. Further, even when the items of monitoring control are increased, it is not necessary to lay the monitoring control cable in the power receiving / transforming equipment 100. Further, even when the number of the power receiving / transforming equipment 100 increases, it is sufficient to change the setting of the power receiving / transforming equipment 100 (for example, set the signal output destination to the state acquisition unit 141). Therefore, the user does not need to lay the monitoring control cable. In this way, users such as observers can more easily perform monitoring and control.

Hereinafter, when it is not distinguished which power receiving / transforming equipment it is, it will be described simply as the power receiving / transforming equipment 100.

第２の実施形態における受変電設備１００は、無線通信装置２００との通信することが出来ない場合に、他の受変電設備１００を介して信号を無線通信装置２００に送信する。以下、具体的に説明する。受信強度判定部１４３は、無線通信装置２００から受信した電波の受信強度が低い場合、他の受変電設備１００（例えば、受変電設備１００ａ）から受信した電波の受信強度を取得する。受信強度判定部１４３は、取得された受信強度が所定の閾値以上であるか否かを判定する。受信強度が所定の閾値以上である場合、受信強度判定部１４３は、電波の送信元となる装置（例えば、受変電設備１００ａ）と無線通信可能であると判定する。受信強度が所定の閾値より小さい場合、受信強度判定部１４３は、電波の送信元となる装置と無線通信可能ではないと判定する。受信強度判定部１４３は、判定結果を通信制御部１４２に出力する。 When the power receiving / transforming equipment 100 in the second embodiment cannot communicate with the wireless communication device 200, the power receiving / transforming equipment 100 transmits a signal to the wireless communication device 200 via the other power receiving / transforming equipment 100. Hereinafter, a specific description will be given. When the reception strength of the radio wave received from the wireless communication device 200 is low, the reception strength determination unit 143 acquires the reception strength of the radio wave received from another power receiving / transforming equipment 100 (for example, the power receiving / transforming equipment 100a). The reception intensity determination unit 143 determines whether or not the acquired reception intensity is equal to or greater than a predetermined threshold value. When the reception strength is equal to or higher than a predetermined threshold value, the reception strength determination unit 143 determines that wireless communication is possible with a device (for example, power receiving / transforming equipment 100a) that is a source of radio waves. When the reception strength is smaller than a predetermined threshold value, the reception strength determination unit 143 determines that wireless communication with the device that is the source of the radio wave is not possible. The reception strength determination unit 143 outputs the determination result to the communication control unit 142.

通信制御部１４２は、受信強度が所定の閾値以上である場合、電波の送信元となる装置に信号を送信する。受信強度が所定の閾値より小さい場合、受信強度判定部１４３は、他の装置から受信強度を取得する。例えば、受信強度判定部１４３は、再度無線通信装置２００から受信した電波の受信強度を取得してもよい。受信強度判定部１４３は、別の受変電設備１００から受信した電波の受信強度を取得してもよい。 When the reception intensity is equal to or higher than a predetermined threshold value, the communication control unit 142 transmits a signal to a device that is a source of radio waves. When the reception strength is smaller than a predetermined threshold value, the reception strength determination unit 143 acquires the reception strength from another device. For example, the reception strength determination unit 143 may acquire the reception strength of the radio wave received from the wireless communication device 200 again. The reception strength determination unit 143 may acquire the reception strength of the radio wave received from another power receiving / transforming facility 100.

図７は、第２の実施形態の無線通信の流れの一具体例を示すシーケンス図である。例えば、受変電設備１００が無線通信装置２００に対して信号を送信する場合に、無線通信が行われる。また、無線通信装置２００が受変電設備１００に対して信号を送信する場合に、無線通信が行われる。図７では、受変電設備１００が無線通信装置２００に対して信号を送信する場合を例として説明する。ステップＳ２１３及びＳ２１４の処理は、図５におけるステップＳ１０５及びＳ１０６の処理と同様であるため、説明を省略する。 FIG. 7 is a sequence diagram showing a specific example of the flow of wireless communication according to the second embodiment. For example, when the power receiving / transforming equipment 100 transmits a signal to the wireless communication device 200, wireless communication is performed. Further, when the wireless communication device 200 transmits a signal to the power receiving / transforming facility 100, wireless communication is performed. In FIG. 7, a case where the power receiving / transforming equipment 100 transmits a signal to the wireless communication device 200 will be described as an example. Since the processing of steps S213 and S214 is the same as the processing of steps S105 and S106 in FIG. 5, the description thereof will be omitted.

受変電設備１００の状態取得部１４１は、受変電設備１００に設けられた電気機器から接点信号又は伝送信号等の信号を取得する（ステップＳ２０１）。受信強度判定部１４３は、無線通信部１０１が受信した電波の受信強度を取得する（ステップＳ２０２）。受信強度は、公知の手法を用いて取得される。受信強度判定部１４３は、取得された受信強度が所定の閾値以上であるか否かを判定する（ステップＳ２０３）。受信強度が所定の閾値以上である場合（ステップＳ２０３：ＹＥＳ）、通信制御部１４２は、取得された信号を無線通信装置２００に送信する（ステップＳ２０４）。 The state acquisition unit 141 of the power receiving / transforming facility 100 acquires a signal such as a contact signal or a transmission signal from the electric device provided in the power receiving / transforming facility 100 (step S201). The reception strength determination unit 143 acquires the reception strength of the radio wave received by the wireless communication unit 101 (step S202). The reception intensity is obtained using a known method. The reception intensity determination unit 143 determines whether or not the acquired reception intensity is equal to or greater than a predetermined threshold value (step S203). When the reception strength is equal to or higher than a predetermined threshold value (step S203: YES), the communication control unit 142 transmits the acquired signal to the wireless communication device 200 (step S204).

受信強度が所定の閾値より小さい場合（ステップＳ２０３：ＮＯ）、受信強度判定部１４３は、受変電設備１００ａから受信した電波の受信強度を取得する（ステップＳ２０５）。受信強度判定部１４３は、取得された受信強度が所定の閾値以上であるか否かを判定する（ステップＳ２０６）。受信強度が所定の閾値より小さい場合（ステップＳ２０６：ＮＯ）、処理は、ステップＳ２０２に遷移する（ステップＳ２０７）。受信強度が所定の閾値以上である場合（ステップＳ２０３：ＹＥＳ）、通信制御部１４２は、取得された信号を受変電設備１００ａに送信する（ステップＳ２０８）。 When the reception intensity is smaller than a predetermined threshold value (step S203: NO), the reception intensity determination unit 143 acquires the reception intensity of the radio wave received from the power receiving / transforming facility 100a (step S205). The reception intensity determination unit 143 determines whether or not the acquired reception intensity is equal to or greater than a predetermined threshold value (step S206). When the reception intensity is smaller than a predetermined threshold value (step S206: NO), the process transitions to step S202 (step S207). When the reception strength is equal to or higher than a predetermined threshold value (step S203: YES), the communication control unit 142 transmits the acquired signal to the power receiving / transforming facility 100a (step S208).

受変電設備１００ａの受信強度判定部１４３ａは、無線通信装置２００から受信した電波の受信強度を取得する（ステップＳ２０９）。受信強度判定部１４３ａは、取得された受信強度が所定の閾値以上であるか否かを判定する（ステップＳ２１０）。受信強度が所定の閾値より小さい場合（ステップＳ２１０：ＮＯ）、処理は、ステップＳ２０９に遷移する（ステップＳ２１１）。受信強度が所定の閾値以上である場合（ステップＳ２１０：ＹＥＳ）、通信制御部１４２は、取得された信号を無線通信装置２００に送信する（ステップＳ２１２）。 The reception strength determination unit 143a of the power receiving / transforming equipment 100a acquires the reception strength of the radio wave received from the wireless communication device 200 (step S209). The reception intensity determination unit 143a determines whether or not the acquired reception intensity is equal to or greater than a predetermined threshold value (step S210). When the reception intensity is smaller than a predetermined threshold value (step S210: NO), the process transitions to step S209 (step S211). When the reception strength is equal to or higher than a predetermined threshold value (step S210: YES), the communication control unit 142 transmits the acquired signal to the wireless communication device 200 (step S212).

このように構成された受変電システム１ａでは、受変電設備１００は無線通信装置２００からの受信強度が所定の閾値以下である場合、他の受変電設備１００ａを経由して監視制御装置３００に信号を送信する。このため、無線通信装置２００と受変電設備１００との通信が不安定になった場合であっても、監視制御装置３００に信号を送信することが可能になる。 In the power receiving / transforming system 1a configured in this way, when the receiving strength from the wireless communication device 200 is equal to or less than a predetermined threshold value, the power receiving / transforming equipment 100 signals the monitoring control device 300 via the other power receiving / transforming equipment 100a. To send. Therefore, even if the communication between the wireless communication device 200 and the power receiving / transforming equipment 100 becomes unstable, it is possible to transmit a signal to the monitoring control device 300.

（第３の実施形態）
次に、第３の実施形態における受変電システム１ｂについて説明する。図８は、第３の実施形態の受変電システム１ｂのシステム構成図である。第３の実施形態における受変電システム１ｂは、複数の受変電設備１００が並べて配置されている点と無線通信部１０１の代わりに無線通信部１０１ｂを備える点とで第１の実施形態とは異なるが、それ以外の構成は同じである。以下、第１の実施形態と異なる点について説明する。 (Third Embodiment)
Next, the power receiving / transforming system 1b according to the third embodiment will be described. FIG. 8 is a system configuration diagram of the power receiving / transforming system 1b of the third embodiment. The power receiving / transforming system 1b in the third embodiment is different from the first embodiment in that a plurality of power receiving / transforming facilities 100 are arranged side by side and a wireless communication unit 101b is provided instead of the wireless communication unit 101. However, the other configurations are the same. Hereinafter, the points different from the first embodiment will be described.

並べて配置された受変電設備１００の下部には、共通の接地母線が配設されている。接地母線は、接地極に接続される。受変電設備１００は、ほぼ直線上に並べて複数配置される。受変電設備１００は、無線通信部１０１ｂと信号用ケーブルで接続されている。 A common ground bus is arranged below the power receiving / transforming equipment 100 arranged side by side. The ground bus is connected to the ground electrode. A plurality of power receiving / transforming equipment 100s are arranged side by side on a substantially straight line. The power receiving / transforming equipment 100 is connected to the wireless communication unit 101b with a signal cable.

無線通信部１０１ｂは、アンテナ等の無線ネットワークインタフェースである。無線通信部１０１ｂは無線通信プロトコルに基づいて、他の装置（例えば、無線通信装置２００）と通信する。無線通信部１０１ｂは、例えば無線ＬＡＮであってもよいし、Ｂｌｕｅｔｏｏｔｈ等の通信方式で通信してもよい。無線通信部１０１ｂは、電気室１０内で送受信される電波を受信する。無線通信部１０１ｂは、信号用ケーブルを介して、各受変電設備１００に接続される。無線通信部１０１ｂは、受変電設備１００から受信した信号を、無線通信装置２００に送信する。 The wireless communication unit 101b is a wireless network interface such as an antenna. The wireless communication unit 101b communicates with another device (for example, the wireless communication device 200) based on the wireless communication protocol. The wireless communication unit 101b may be, for example, a wireless LAN, or may communicate by a communication method such as Bluetooth. The wireless communication unit 101b receives radio waves transmitted and received in the electric room 10. The wireless communication unit 101b is connected to each power receiving / transforming facility 100 via a signal cable. The wireless communication unit 101b transmits the signal received from the power receiving / transforming facility 100 to the wireless communication device 200.

このように構成された受変電システム１ｂでは、１台の無線通信部１０１ｂが複数の受変電設備１００の信号を監視制御装置３００に送信する。このため、無線通信部を備えない監視制御装置３００が電気室１０に設けられている場合であっても監視制御用ケーブルを電気室１０内に敷設する必要がなくなる。このため、ユーザは、より簡単に監視制御を行うことが可能になる。 In the power receiving / transforming system 1b configured in this way, one wireless communication unit 101b transmits signals of a plurality of power receiving / transforming equipment 100 to the monitoring control device 300. Therefore, even when the monitoring control device 300 without the wireless communication unit is provided in the electric room 10, it is not necessary to lay the monitoring control cable in the electric room 10. Therefore, the user can perform monitoring control more easily.

上述の実施形態では、無線通信装置２００が１台である場合について説明した。しかし、無線通信装置２００は、電気室１０内に複数設けられてもよい。このように構成されることで、１台の無線通信装置２００が故障した場合であっても、受変電設備１００は、監視制御装置３００に信号を送信することができる。 In the above-described embodiment, the case where the number of wireless communication devices 200 is one has been described. However, a plurality of wireless communication devices 200 may be provided in the electric room 10. With this configuration, even if one wireless communication device 200 fails, the power receiving / transforming equipment 100 can transmit a signal to the monitoring / controlling device 300.

上記各実施形態では、状態取得部１４１、通信制御部１４２、２４１、３５１、受信強度判定部１４３及び出力制御部３５２はソフトウェア機能部であるものとしたが、ＬＳＩ等のハードウェア機能部であってもよい。 In each of the above embodiments, the state acquisition unit 141, the communication control unit 142, 241, 351 and the reception strength determination unit 143 and the output control unit 352 are software function units, but they are hardware function units such as LSI. You may.

以上説明した少なくともひとつの実施形態によれば、無線通信部１０１を持つことにより、より簡単に受変電設備１００の監視制御をすることができる。 According to at least one embodiment described above, by having the wireless communication unit 101, it is possible to more easily monitor and control the power receiving / transforming equipment 100.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれると同様に、特許請求の範囲に記載された発明とその均等の範囲に含まれるものである。 Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, as well as in the scope of the invention described in the claims and the equivalent scope thereof.
