PROBLEM TO BE SOLVED: To provide means composing a network between plural communication apparatuses disposed in a train without manual operation.SOLUTION: A network ID created by a master station 11 arranged to a train 9 is transmitted by radio communication to slave stations 12A(1), 12B(1), 12A(2), ..., 12B(n) using a relay system. The slave station 12 determines whether or not the master station 11 being a transmission source of an electric wave or the slave station 12 is disposed on a train 91 on the same orbit on the basis of the phase difference between electric waves received by two antennas arranged side by side in a longitudinal direction of the train 91. The network ID indicated by the electric wave transmitted from the master station 11 or slave station 12 disposed on the train 91 on the same orbit is stored as the network ID discriminating the network to which a local station belongs. The master and slave stations 11 and 12 send and receive actual data using a common network ID.SELECTED DRAWING: Figure 1

    【課題】人手によらず列車に配置された複数の通信装置の間でネットワークを構成する手段を提供する。【解決手段】列車9に配置された主局11により生成されたネットワークIDは、無線により、従局12A(1)、従局12B(1)、従局12A(2)、・・・、従局12B(n)へとリレー式に送信される。従局12は、車両91の左右方向に並んで配置された2つのアンテナにより受信した電波の位相差に基づき、電波の送信元の主局11または従局12が同じ軌道上の車両91に配置されているか否かを判定し、同じ軌道上の車両91に配置されている主局11または従局12から送信された電波が示すネットワークIDを、自局が属するネットワークを識別するネットワークIDとして記憶する。主局11および従局12は、共有するネットワークIDを用いて実データの送受信を行う。【選択図】図1
