本発明により、電源タップを使って電力線通信機器を接続する場合に、電力線通信のネットワーク構成を管理サーバが認識できるようになる。   According to the present invention, when a power line communication device is connected using a power strip, the management server can recognize the network configuration of the power line communication.

以下、図面を参照して、本発明の実施例を詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１は、本発明の第１実施例である電源タップの概略構成図を示す。   FIG. 1 shows a schematic configuration diagram of a power strip according to a first embodiment of the present invention.

電源タップ１０の一端に電源プラグ１２があり、他端に複数（本実施例では４つ）のコンセント１４（１４−１〜１４−４）がある。電源プラグ１２にはＲＦＩＤタグ１６が貼り付け又は埋め込まれている。電源プラグ１２とコンセント１４との間の電力線に電力線通信（ＰＬＣ）モデム１８が接続する。ＲＦＩＤタグ１６には、電源タップ１０を特定する情報、例えば、ＰＬＣモデム１８を特定する情報を直接又は間接に示す識別情報が格納されている。   There is a power plug 12 at one end of the power tap 10, and there are a plurality (four in this embodiment) of outlets 14 (14-1 to 14-4) at the other end. An RFID tag 16 is attached or embedded in the power plug 12. A power line communication (PLC) modem 18 is connected to the power line between the power plug 12 and the outlet 14. The RFID tag 16 stores information for specifying the power strip 10, for example, identification information that directly or indirectly indicates information for specifying the PLC modem 18.

本実施例では、コンセント１４に接続される電源プラグ３０−１，３０−２には、それぞれＲＦＩＤタグ３２−１，３２−２が貼り付け又は埋め込まれている。ＲＦＩＤタグ３２−１，３２−２には、電源プラグ３０−１，３０−２の先に接続されているＰＬＣモデム（図示せず）を特定する情報、又は、そのＰＬＣモデムを内蔵する電子機器を特定する情報を直接又は間接に示す識別情報が格納されている。   In the present embodiment, RFID tags 32-1 and 32-2 are attached or embedded in the power plugs 30-1 and 30-2 connected to the outlet 14, respectively. The RFID tags 32-1 and 32-2 include information for specifying a PLC modem (not shown) connected to the ends of the power plugs 30-1 and 30-2, or an electronic device incorporating the PLC modem. The identification information which directly or indirectly indicates the information specifying the ID is stored.

電源タップ１０は、更に、コンセント１４に接続される電源プラグ３０−１，３０−２に付加されたＲＦＩＤタグ３２−１，３２−２の識別情報を読み取るＲＦＩＤタグリーダ２０を具備する。ＲＦＩＤタグリーダ２０のＲＦＩＤ感知距離は、コンセント１４−１〜１４−４から数ｃｍ程度に設定されている。制御回路２２は、ＲＦＩＤタグリーダ２０で読み取られた識別情報をメモリ２４に記憶しつつ、電源タップ１０の識別情報（例えば、ＰＬＣモデム１８の識別情報）と共に、ＰＬＣモデム１８により後述する管理サーバ４６に通知する。   The power tap 10 further includes an RFID tag reader 20 that reads identification information of the RFID tags 32-1 and 32-2 attached to the power plugs 30-1 and 30-2 connected to the outlet 14. The RFID sensing distance of the RFID tag reader 20 is set to about several centimeters from the outlets 14-1 to 14-4. The control circuit 22 stores the identification information read by the RFID tag reader 20 in the memory 24 and, together with the identification information of the power strip 10 (for example, the identification information of the PLC modem 18), the control circuit 22 sends the identification information to the management server 46 described later. Notice.

電源タップ１０の電源プラグ１２は、家庭内又はオフィス内の電力線４０のコンセント４２に接続される。電力線４０の別のコンセント４４には、管理サーバ４６の電源プラグ４８が接続する。管理サーバ４６と電源プラグ４８の間にはＰＬＣモデム５０が接続する。ＰＬＣモデム５０は、電力線４０を介して電源タップ１０のＰＬＣモデム１８と通信することができる。管理サーバ４６は、ＰＬＣモデム５０により、電源タップ１０のＰＬＣモデム１８からの情報を受信できる。   The power plug 12 of the power strip 10 is connected to the outlet 42 of the power line 40 in the home or office. A power plug 48 of the management server 46 is connected to another outlet 44 of the power line 40. A PLC modem 50 is connected between the management server 46 and the power plug 48. The PLC modem 50 can communicate with the PLC modem 18 of the power strip 10 via the power line 40. The management server 46 can receive information from the PLC modem 18 of the power strip 10 by the PLC modem 50.

本実施例の使用方法を説明する。電源タップ１０の電源プラグ１２をコンセント４２に接続する。これにより、ＰＬＣモデム１８、ＲＦＩＤタグリーダ２０、制御回路２２及びメモリ２４は給電され、動作状態になる。制御回路２２は、電源タップ１０を特定する識別情報をＰＬＣモデム１８を介して管理サーバ４６に送信する。電源タップ１０を特定する情報は、例えば、ＰＬＣモデム１８を特定する情報であり、ＲＦＩＤタグ１６に識別情報として格納されている。これにより、管理サーバ４６は、特定の電源タップ１０が電力線４０に接続されたことを知る。 A method of using this embodiment will be described. The power plug 12 of the power strip 10 is connected to the outlet 42. As a result, the PLC modem 18, the RFID tag reader 20, the control circuit 22 and the memory 24 are supplied with power and are in an operating state. The control circuit 22 transmits identification information for specifying the power tap 10 to the management server 46 via the PLC modem 18. The information for specifying the power strip 10 is, for example, information for specifying the PLC modem 18 and is stored as identification information in the RFID tag 16 . Thereby, the management server 46 knows that the specific power strip 10 is connected to the power line 40.

電源タップ１０のコンセント１４−１に、ＲＦＩＤタグ３２−１が付加された電源プラグ３０−１が接続されたとする。ＲＦＩＤタグリーダ２０は、コンセント１４−１に接続された電源プラグ３０−１のＲＦＩＤタグ３２−１の識別情報を読み取り、読み取った識別情報を制御回路２２に出力する。制御回路２２は、ＲＦＩＤタグリーダ２０で読み取られた識別情報をメモリ２４に記憶する。そして、制御回路２２は、読み取った識別情報と自己の識別情報とを対にして、ＰＬＣモデム１８により管理サーバ４６に通知する。電源プラグ３０−１のＲＦＩＤタグ３２−１には、電源プラグ３０−１の先に接続されているＰＬＣモデムを特定する識別情報、又は、そのＰＬＣモデムを内蔵する電子機器を特定する識別情報が格納されているので、管理サーバ４６は、電源タップ１０からのこれらの情報から、電力線４０に電源タップ１０を介してどのＰＬＣモデム又は電子機器が接続されたかを把握できる。   It is assumed that the power plug 30-1 to which the RFID tag 32-1 is added is connected to the outlet 14-1 of the power tap 10. The RFID tag reader 20 reads the identification information of the RFID tag 32-1 of the power plug 30-1 connected to the outlet 14-1, and outputs the read identification information to the control circuit 22. The control circuit 22 stores the identification information read by the RFID tag reader 20 in the memory 24. Then, the control circuit 22 makes a pair of the read identification information and its own identification information and notifies the management server 46 by the PLC modem 18. The RFID tag 32-1 of the power plug 30-1 has identification information for specifying a PLC modem connected to the tip of the power plug 30-1, or identification information for specifying an electronic device incorporating the PLC modem. Since it is stored, the management server 46 can grasp which PLC modem or electronic device is connected to the power line 40 via the power tap 10 from these pieces of information from the power tap 10.

コンセント４２自体に、ＲＦＩＤタグ１６の識別情報を読み取るＲＦＩＤタグリーダと、読み取った識別情報を管理サーバ４６に送信するＰＬＣモデムを組み込んでおくことにより、管理サーバ４６は、既設のどのコンセントに電源タップ１０が接続されたかも把握できる。これにより、家庭内又はオフィス内での電力線ネットワークのヒエラルキーを、各ＰＬＣモデムが壁又は床に既設のコンセントに最終的に接続するかも含めて、完全に把握できる。   By incorporating an RFID tag reader that reads the identification information of the RFID tag 16 and a PLC modem that transmits the read identification information to the management server 46 in the outlet 42 itself, the management server 46 is connected to the power outlet 10 in any existing outlet. You can also see if is connected. As a result, the hierarchy of the power line network in the home or office can be completely grasped, including whether each PLC modem is finally connected to an existing outlet on the wall or floor.

管理サーバ４６は、このように得られた電源タップの位置情報を用いて、電源タップに接続された特定の端末間の通信のみを許可するネットワークを構成することができる。   The management server 46 can configure a network that allows only communication between specific terminals connected to the power strip using the position information of the power strip obtained in this way.

電源タップが１段の場合を説明したが、勿論、複数段に及ぶ場合にも、各電源タップが、上述のようにコンセントに接続する電源プラグの識別情報と自己の識別情報を管理サーバ４６に送信することで、管理サーバ４６は、ネットワーク構成を全体的に認識できる。   Although the case where the power strip has one stage has been described, of course, even when the power strip has a plurality of stages, each power strip transmits the identification information of the power plug connected to the outlet and its own identification information to the management server 46 as described above. By transmitting, the management server 46 can recognize the network configuration as a whole.

特定の説明用の実施例を参照して本発明を説明したが、特許請求の範囲に規定される本発明の技術的範囲を逸脱しないで、上述の実施例に種々の変更・修整を施しうることは、本発明の属する分野の技術者にとって自明であり、このような変更・修整も本発明の技術的範囲に含まれる。   Although the invention has been described with reference to specific illustrative embodiments, various modifications and alterations may be made to the above-described embodiments without departing from the scope of the invention as defined in the claims. This is obvious to an engineer in the field to which the present invention belongs, and such changes and modifications are also included in the technical scope of the present invention.
