Description
図3は、図1のPLC管理装置20Aの構成を示すブロック図である。PLC管理装置20Aは、PLC回路21A、制御回路22A、及び通信回路23Aを備える。制御回路22Aは、PLC回路21Aを用いて検針装置10−1〜10−15と通信し、通信回路23Aを用いて電力会社設備30と通信する。
FIG. 3 is a block diagram showing a configuration of the
通知信号は、前述のように、ルーティングのために定期的にブロードキャストされるHelloパケット、又は、各ネットワーク内で定期的又は非定期的に送受信される他の任意のパケットであってもよい。図6は、通知信号がHelloパケットである場合を示す。検針装置10−Nの制御回路12は、PLC回路13を用いて、PLCネットワーク100Aに含まれる他の検針装置及びPLC管理装置20AによってPLCネットワーク100A内で定期的にブロードキャストされる、Helloパケットを受信する。各Helloパケットは、PLCネットワーク100Aの空き容量の情報を含む。これにより、制御回路12は、PLC回路13を用いて、PLCネットワーク100Aに含まれる少なくとも1つの他の検針装置又はPLC管理装置20Aから、PLCネットワーク100Aの空き容量の情報を取得する。制御回路12は、無線通信回路14を用いて、無線ネットワーク100Bに含まれる他の検針装置及び無線管理装置20Bによって無線ネットワーク100B内で定期的にブロードキャストされる、Helloパケットを受信する。各Helloパケットは、無線ネットワーク100Bの空き容量の情報を含む。これにより、制御回路12は、無線通信回路14を用いて、無線ネットワーク100Bに含まれる少なくとも1つの他の検針装置又は無線管理装置20Bから、無線ネットワーク100Bの空き容量の情報を取得する。
As described above, the notification signal may be a Hello packet that is periodically broadcast for routing, or any other packet that is transmitted or received periodically or irregularly in each network. FIG. 6 shows a case where the notification signal is a Hello packet. The control circuit 12 of the meter-reading apparatus 10-N receives the Hello packet regularly broadcast in the PLC network 100A by the other meter-reading apparatus and
