Description
図3は、図1の検針装置1の構成を示すブロック図である。検針装置1は、電力測定器31、制御回路32、PLC回路33、及び無線通信回路34を備える。電力測定器31は、宅内機器(図示せず)の消費電力量を測定する。PLC回路33は、制御回路32の制御下で、他の検針装置2〜4及び管理装置10と通信する。無線通信回路34は、制御回路32の制御下で、他の検針装置2〜4及び管理装置10と通信する。制御回路32は、測定された消費電力量を、PLC回路33又は無線通信回路34を用いて管理装置10に通知する。他の検針装置2〜4もまた、検針装置1と同様に構成される。
FIG. 3 is a block diagram showing a configuration of the meter-reading apparatus 1 of FIG. The meter-reading device 1 includes a power measuring device 31, a control circuit 32, a PLC circuit 33, and a wireless communication circuit 34. The power meter 31 measures the amount of power consumption of a home device (not shown). The PLC circuit 33 communicates with the other meter-reading apparatuses 2 to 4 and the management apparatus 10 under the control of the control circuit 32. The wireless communication circuit 34 communicates with the other meter-reading apparatuses 2 to 4 and the management apparatus 10 under the control of the control circuit 32. The control circuit 32 notifies the management device 10 of the measured power consumption using the PLC circuit 33 or the wireless communication circuit 34. The other meter-reading apparatuses 2-4 are also comprised similarly to the meter-reading apparatus 1. FIG.
図2及び図3は、PLC回路(12,33)及び無線通信回路(13,34)を2つの別個のモジュールとして示すが、PLC回路及び無線通信回路は単一のモジュール又はチップとして提供されてもよい。また、図3は、電力測定器31と通信回路(PLC回路33及び無線通信回路34)とが一体型の構成を示すが、電力測定器31と通信回路とは、別個のモジュールとして提供されてもよい。
2 and 3 show the PLC circuit (12, 33) and the wireless communication circuit (13, 34) as two separate modules, the PLC circuit and the wireless communication circuit are provided as a single module or chip. Also good. 3 shows a configuration in which the power meter 31 and the communication circuit (the PLC circuit 33 and the wireless communication circuit 34) are integrated, the power meter 31 and the communication circuit are provided as separate modules. Also good.
図1の通信システムにおいて、ある通信方式(通信媒体)を用いた通信に失敗したとき、同じ通信方式のリンクを含む別のルートを用いて通信しても、通信路の状況(ノイズ状況)に実質的に変化がなく、再び通信に失敗する可能性がある。しかしながら、図4〜図6のルーティングに示すように、メインルートを用いた通信の失敗を検出したとき、代替ルートを用いて検針装置4との通信を開始することにより、通信を確立する可能性を向上することができる。図4〜図6のルーティングによれば、各通信方式(メディア)を用いたときの通信状況に応じて、通信信頼性の高い代替ルートを選択することができ、通信システム全体の通信信頼性が向上する。
In the communication system of FIG. 1, when communication using a certain communication method (communication medium) fails, even if communication is performed using another route including a link of the same communication method, the communication path condition (noise condition) is changed. There is virtually no change and communication may fail again. However, as shown in the routing of FIGS. 4 to 6, when communication failure using the main route is detected, communication may be established by starting communication with the meter-reading device 4 using the alternative route. Can be improved . According to the routing of FIGS. 4 to 6, an alternative route with high communication reliability can be selected according to the communication status when each communication method (media) is used, and the communication reliability of the entire communication system is improved. improves.
