Description

本発明は、電力線通信システムにおいて電力線通信モデムにネットワーク設定情報登録するシステムに関する。   The present invention relates to a system for registering network setting information in a power line communication modem in a power line communication system.

電力線通信ネットワークでは、通信する電力線通信モデムを特定するために、ネットワークを特定するネットワーク情報等を設定する必要がある。ネットワーク情報等は、従来、電力線通信モデムに予め登録されているか、またはユーザが電力線通信モデムに接続したコンピュータ（ＰＣ）等を用い、電力線通信ネットワークに接続して設定する。   In a power line communication network, in order to specify a power line communication modem for communication, it is necessary to set network information for specifying the network. Conventionally, the network information or the like is registered in advance in the power line communication modem, or is set by connecting to the power line communication network using a computer (PC) connected to the power line communication modem by the user.

電力線通信システムでは、同じネットワークを構成する電力線通信モデムを識別するために、各モデムにネットワークを設定する必要がある。ネットワークの設定には、通常、ネットワークＩＤと認証キー（パスワード又は暗号キー等）が使用される。   In a power line communication system, it is necessary to set a network for each modem in order to identify power line communication modems constituting the same network. For network setting, a network ID and an authentication key (password or encryption key) are usually used.

また、各モデムに用意したＤＩＰ（Ｄｕａｌ Ｉｎｌｉｎｅ Ｐａｃｋａｇｅ）スイッチでＩＤを設定する方法が知られている。サーバ又は専用装置が同じネットワーク内のモデムにネットワーク設定情報を設定する方法が、特許文献１，２に記載されている。   There is also known a method of setting an ID with a DIP (Dual Inline Package) switch prepared for each modem. Patent Documents 1 and 2 describe a method in which a server or a dedicated device sets network setting information in a modem in the same network.

特許文献２には、電源断によってネットワーク設定情報を消失する電力消費端末と、電力消費端末に関するカスタマイズデータを記憶し、電源断によっても記憶を保持し、電源供給の復帰時にカスタマイズデータをブロードキャストする情報配信装置からなる電力線ネットワークシステムが、記載されている。
特開２０００−２９５２５８号公報 特開２００１−１１７６７８号公報 Patent Document 2 stores information about a power consuming terminal that loses network setting information when power is turned off, and customization data related to the power consuming terminal, holds the memory even when power is turned off, and broadcasts customized data when power supply is restored A power line network system consisting of distribution devices is described.
JP 2000-295258 A JP 2001-117678 A

サーバ又は情報配信装置により個々の電力線通信モデムにネットワーク設定情報を設定する方法は、ネットワークを限定する手段を設けないと、本来、同じネットワークに属すべきでない電力線通信モデムを同一ネットワーク内のものであると誤認してネットワークに参加させてしまう。   A method for setting network setting information to individual power line communication modems by a server or an information distribution apparatus is such that power line communication modems that should not belong to the same network are originally in the same network unless means for limiting the network is provided. It will be mistaken and let you join the network.

電力線通信モデムに予め特定のネットワーク名等が登録されていれば、このネットワーク名を確認することで、適切に認証キーを設定できる。しかし、この方法では、ユーザは、接続先のネットワークを自由に選択できなくなる。   If a specific network name or the like is registered in advance in the power line communication modem, an authentication key can be appropriately set by confirming this network name. However, with this method, the user cannot freely select a connection destination network.

また、ユーザが電力線通信モデムをＰＣ等に接続して設定する方式では、ネットワーク及びＰＣ等の知識が無い一般のユーザには、設定が困難である。   Further, in the method in which the user connects and sets the power line communication modem to a PC or the like, setting is difficult for a general user who does not have knowledge of the network and the PC.

さらに、管理者が許可した特定の電力線通信モデムのみをネットワーク接続可能とすることは、従来の方法では困難であった。   Furthermore, it has been difficult with the conventional method to connect only a specific power line communication modem permitted by the administrator to the network.

本発明は、このような不都合を解消し、簡易な操作で適切にネットワーク設定情報を登録できるネットワーク設定情報登録システムを提示することを目的とする。   An object of the present invention is to provide a network setting information registration system capable of solving such inconvenience and appropriately registering network setting information with a simple operation.

本発明に係るネットワーク設定情報登録システムは、第１の電力線通信モデム装置から第２の電力線通信モデム装置にネットワーク設定情報を転送して、当該ネットワーク設定情報を当該第２の電力線通信モデム装置に登録するシステムであって、当該第１の電力線通信モデム装置が、当該ネットワーク設定情報を記憶する第１のメモリと、送信開始指示手段と、当該送信開始指示手段の送信開始指示に従い、当該ネットワーク設定情報を無線信号に載せて出力する無線信号送信装置とを具備し、当該第２の電力線通信モデム装置が、受信開始指示手段と、当該受信開始指示手段の受信開始指示から所定期間、受信を待機し、その待機中に当該無線信号送信装置から出力される当該無線信号を受信する無線信号受信装置と、当該無線信号で搬送される当該ネットワーク設定情報を記憶する第２のメモリと、当該ネットワーク設定情報を登録する制御回路とを具備することを特徴とする。 The network setting information registration system according to the present invention transfers network setting information from a first power line communication modem device to a second power line communication modem device, and registers the network setting information in the second power line communication modem device. The first power line communication modem device is configured to perform the network setting information according to a first memory for storing the network setting information, a transmission start instruction unit, and a transmission start instruction from the transmission start instruction unit. The second power line communication modem device waits for reception for a predetermined period from the reception start instruction of the reception start instruction means and the reception start instruction of the reception start instruction means. a radio signal receiver to receive the radio signals output from the radio signal transmitting apparatus during the standby, transportable in the wireless signal A second memory for storing the network setting information, characterized by comprising a control circuit registers the network configuration information.

本発明によれば、電力線通信ネットワークに新たに参加する電力線通信モデムに非常に簡単にネットワーク設定情報を登録できる。自由なネットワークＩＤを利用可能にするとして、せいぜい、最初の１台目にマニュアルでネットワーク設定情報を登録するだけで済み、ユーザの登録負担が大幅に軽減される。   According to the present invention, network setting information can be registered very easily in a power line communication modem newly participating in the power line communication network. Assuming that a free network ID can be used, at most, it is only necessary to manually register the network setting information on the first unit, and the registration burden on the user is greatly reduced.

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実施例の概略構成ブロック図を示す。本実施例では、親機又はマスターとなるＰＬＣモデム装置２０には、ネットワークＩＤと認証キーを予め登録されており、新たにＰＬＣモデム装置４０をＰＬＣネットワークに参加させる。   FIG. 1 shows a schematic block diagram of a first embodiment of the present invention. In the present embodiment, the network modem and the authentication key are registered in advance in the PLC modem device 20 serving as the master unit or the master, and the PLC modem device 40 is newly added to the PLC network.

建物内の電力線１０にコンセント１２，１４が接続する。ＰＬＣモデム装置２０は、ＰＬＣモデム回路２２、制御回路２４、メモリ２６及び広出射角の発光素子２８を具備する。電源プラグ３０は、電力線３２を介してＰＬＣモデム回路２２に接続する。ＰＬＣモデム回路２２はまた、電力線３４及び信号線３６を介して、通信端末となる電気機器３８と接続する。   Outlets 12 and 14 are connected to the power line 10 in the building. The PLC modem device 20 includes a PLC modem circuit 22, a control circuit 24, a memory 26, and a light emitting element 28 having a wide emission angle. The power plug 30 is connected to the PLC modem circuit 22 through the power line 32. The PLC modem circuit 22 is also connected to an electric device 38 serving as a communication terminal via a power line 34 and a signal line 36.

電源プラグ３０はコンセント１２に接続される。電力線１０上の電力は、コンセント１２、電源プラグ３０、電力線３２を介してモデム装置２０に供給され、更に、ＰＬＣモデム回路２２及び電力線３４を介して電気機器３８に供給される。ＰＬＣモデム装置２０は電気機器３８に内蔵されることもある。メモリ２６には予め、ＰＬＣネットワークの構築者又はユーザにより、ＰＣ等を使って、ネットワークＩＤと認証キーを予め登録されている。認証キーは、パスワードと呼ばれたり、暗号キーと呼ばれることもあり、更には、これらが別々に用意されることもある。   The power plug 30 is connected to the outlet 12. The power on the power line 10 is supplied to the modem device 20 through the outlet 12, the power plug 30, and the power line 32, and is further supplied to the electrical device 38 through the PLC modem circuit 22 and the power line 34. The PLC modem device 20 may be built in the electric device 38. In the memory 26, a network ID and an authentication key are registered in advance by a PLC network builder or user using a PC or the like. The authentication key may be called a password or an encryption key, and these may be prepared separately.

同様に、新たにＰＬＣネットワークに参加するＰＬＣモデム装置４０は、ＰＬＣモデム回路４２、制御回路４４、メモリ４６及び受光素子４８を具備する。電源プラグ５０は、電力線５２を介してＰＬＣモデム回路４２に接続する。ＰＬＣモデム回路４２はまた、電力線５４及び信号線５６を介して、通信端末となる電気機器５８と接続する。電源プラグ５０はコンセント１４に接続される。電力線１０上の電力は、コンセント１４、電源プラグ５０及び電力線５２を介してＰＬＣモデム装置４０に供給され、更に、ＰＬＣモデム回路４２及び電力線５４を介して電気機器５８に供給される。ＰＬＣモデム装置４０は電気気５８に内蔵されることもある。   Similarly, the PLC modem device 40 newly participating in the PLC network includes a PLC modem circuit 42, a control circuit 44, a memory 46, and a light receiving element 48. The power plug 50 is connected to the PLC modem circuit 42 via the power line 52. The PLC modem circuit 42 is also connected to an electrical device 58 serving as a communication terminal via a power line 54 and a signal line 56. The power plug 50 is connected to the outlet 14. The power on the power line 10 is supplied to the PLC modem device 40 through the outlet 14, the power plug 50, and the power line 52, and further supplied to the electrical equipment 58 through the PLC modem circuit 42 and the power line 54. The PLC modem device 40 may be built in the electric air 58.

本実施例では、ＰＬＣモデム装置２０のメモリ２６には、先に説明したように、電力線１０を使うＰＬＣネットワークを特定するネットワーク設定情報（ネットワークＩＤと認証キー）が登録されている。   In the present embodiment, as described above, the network setting information (network ID and authentication key) for specifying the PLC network that uses the power line 10 is registered in the memory 26 of the PLC modem device 20.

ユーザは、このＰＬＣネットワークに新たに参加させるＰＬＣモデム装置４０を調達したとき、ＰＬＣモデム装置４０を電源オン状態にして、受光素子４８を発光素子２８に対面させる。この状態で、ＰＬＣモデム装置２０，４０の図示しないスイッチ等をオンにすることで、ＰＬＣモデム装置２０には、ネットワーク設定情報の発光素子２８からの出力を指示し、ＰＬＣモデム装置４０には、受光素子４８によるネットワーク設定情報の受信を指示する。実質的に同時にＰＬＣモデム装置２０，４０を電源オン状態にすることを、ネットワーク設定情報の送信と受信の指示としてもよい。   When the user procures a PLC modem device 40 to newly join the PLC network, the user turns on the PLC modem device 40 and causes the light receiving element 48 to face the light emitting element 28. In this state, by turning on a switch or the like (not shown) of the PLC modem devices 20 and 40, the PLC modem device 20 is instructed to output the network setting information from the light emitting element 28. The reception of network setting information by the light receiving element 48 is instructed. It is also possible to use the network setting information transmission and reception instructions to turn on the PLC modem devices 20 and 40 substantially simultaneously.

この指示に従い、ＰＬＣモデム装置２０の制御回路２４は、メモリ２６からネットワーク設定情報を読み出して、発光素子２８に印加する。これにより、ネットワーク設定情報が、光信号としてＰＬＣモデム装置４０の受光素子４８に向けて出力される。   In accordance with this instruction, the control circuit 24 of the PLC modem device 20 reads the network setting information from the memory 26 and applies it to the light emitting element 28. Thereby, network setting information is output toward the light receiving element 48 of the PLC modem device 40 as an optical signal.

他方、ＰＬＣモデム装置４０は、上記指示に従い所定期間、ネットワーク設定情報の受信を待機する。受光素子４８は、ＰＬＣモデム装置２０からの光信号を電気信号に変換して、制御回路４４に入力する。制御回路４４は、その電気信号からネットワーク設定情報を復調し、メモリ４６に格納すると共に、ＰＬＣモデム装置４０に設定する。これにより、ＰＬＣモデム装置４０は、ＰＬＣモデム装置２０のＰＬＣネットワークに参加でき、以後、ＰＬＣモデム装置２０，４０は、登録されたネットワーク設定情報を使い、電力線１０を介して通信する。   On the other hand, the PLC modem device 40 waits for reception of network setting information for a predetermined period in accordance with the above instruction. The light receiving element 48 converts the optical signal from the PLC modem device 20 into an electric signal and inputs it to the control circuit 44. The control circuit 44 demodulates the network setting information from the electric signal, stores it in the memory 46, and sets it in the PLC modem device 40. Thereby, the PLC modem device 40 can participate in the PLC network of the PLC modem device 20, and thereafter, the PLC modem devices 20 and 40 communicate via the power line 10 using the registered network setting information.

ＰＬＣモデム装置２０，４０間の通信に光空間伝送を使用したが、電波信号又は音響信号でもよいことは勿論である。勿論、そのような電波信号又は音響信号の強度は、至近距離内に到達できる程度の微弱なものとする。   Although optical space transmission is used for communication between the PLC modem devices 20 and 40, it is needless to say that radio wave signals or acoustic signals may be used. Of course, the intensity of such a radio wave signal or acoustic signal is weak enough to reach a close range.

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.
